    The invention relates to a vehicle chassis frame for a counterweight truck, wherein the chassis frame at one vehicle side has a side chassis opening for horizontal removal and insertion of a drive device module in an assembly room.
    Counterbalance trucks are known with either a battery electric type driveline (so-called battery truck) or with an internal combustion engine type driveline (so-called combustion engine truck). In the case of a battery-electric drive line, a drive battery or single-hybrid drive unit with a current receiving device and a battery as an electric energy source device are provided, the drive battery or battery providing a drive device formed of at least one electric drive motor and an electric motor driving a hydraulic pump for working hydraulics and / or electric control hydraulics. . In recent times, such electric counterbalanced trucks have an increasingly so-called lateral battery change in the horizontal direction, in which the drive battery or the hybrid drive unit can be inserted or removed through an opening in the side of the vehicle chassis frame in an assembly room. A vehicle chassis frame for an electric counterbalance truck type of battery is known, for example, from DE 102 48 657. Such vehicle chassis frames have an asymmetrical construction, when at one vehicle side a chassis opening in the side for replacing the drive battery is arranged.
    In the case of counterbalanced trucks with an internal combustion engine type driveline, an internal combustion engine is provided as an energy source for driving the vehicle and for driving the hydraulic pump for working hydraulics and / or steering hydraulics. In such counterbalance trucks which are driven by an internal combustion engine, embodiments of the driveline are known as electric drive (internal combustion engine-electric motor type drive system) or as hydrostatic drive (internal combustion engine-hydrostate type drive system). In an internal combustion engine-electric type drive system with an electric drive device, the driveline comprises a power emitting energy supply unit, which is formed by an internal combustion engine drive generator, which generates the electrical energy for at least one drive motor. The drive motor is generally designed as an alternating current motor, for example an asynchronous motor, to which a converter is connected. The converter here presents a power electronics which transmits alternator alternating voltage to a direct voltage system, from which the voltage system of the alternating current motor is provided. Such internal combustion engine-electric drive systems exhibit good controllability with high efficiencies. In an internal combustion engine-hydrostatic engine type drive system with a hydrostatic driveline, the drive comprises a hydraulic pump driven by the internal combustion engine for operation, which is connected to one or more hydraulic drive motors, usually in a closed circuit. The hydraulic pump arranged for supplying the working hydraulics and / or the steering hydraulics is driven on counterbalanced trucks by an internal combustion engine type driveline as well as on an internal combustion engine-electric type drive system also by an internal combustion hydrostatic engine type drive system directly by the internal combustion engine. The vehicle chassis frame of an internal combustion engine type counterbalanced truck usually comprises two lateral disc-shaped side beams. Such a vehicle chassis for an internal combustion engine type counterbalanced truck with a symmetrical construction is known from EP 1 386 897 B1.
    Therefore, in the manufacture of industrial trucks, different chassis frame concepts and different vehicle chassis frames are required for counterbalance trucks with a combustion engine type driveline engine and counterbalanced trucks with a driveline of battery-electric type, which increases the manufacturing cost.
    The object of the invention is to provide a vehicle chassis frame according to the preamble, with which both counterweight trucks which are battery-electrically powered and also counterweight trucks which are powered by an internal combustion engine can be manufactured in a cost-effective manner.
    This object is achieved according to the invention in that the vehicle chassis frame at the side opposite the side lying in the vehicle side with chassis opening within the area of the unit space is designed as a longitudinally arranged, closed hollow body, which is designed as a container for surface liquid, especially as a container for working fluid. In the vehicle chassis frame according to the invention, the longitudinal side of the wide vehicle, which is opposite the longitudinal side of the vehicle provided with the chassis opening, is formed in the area of the unit space by a closed hollow body extending in the longitudinal direction of the vehicle over the unit space. the employee hydraulics supplying the hydraulic system. Due to the chassis frame structure provided with a closed hollow body and thus provided with a closed cavity on the vehicle side opposite the opening in the vehicle side, the torsional rigidity and bending stiffness of the asymmetrical vehicle chassis frame are increased. This makes it possible to dimension the chassis opening lying in the side in such a way that both a drive battery and an engine unit with an internal combustion engine and auxiliary unit can be removed from and inserted into the unit space through the opening in the side in the horizontal direction. The use of closed hole bodies of the vehicle chassis frame as a liquid container for the working hydraulics of the counterbalanced truck leads to further advantages, as the hollow body can be used for the same purpose both in a counterweight truck driven by an internal combustion engine and in a counterbalanced truck.
    Preferably, the hollow body has a rectangular cross-section. With such a cross section, an effective increase in the torsional rigidity and bending stiffness of the vehicle chassis frame can be achieved through the cavity in the vehicle chassis frame formed by the closed hollow body.
    According to a preferred embodiment of the invention, the vehicle chassis frame is formed of two-length frame side beams, each of which in a rear area is provided with a fixed removable attachment at a rear counterweight of the counterweight truck and forms a crossbar in which the front area is detachably connected to the frame. Such a vehicle chassis frame, which consists of two frame side beams, in which the rear area of each is detachably attached to a counterweight, for example by corresponding screw joints and each front area is reinforced with a crossbar, which is detachably connected to the inner side beams, for example by corresponding screw joints. with welded vehicle chassis frames low manufacturing cost for the chassis frame components.
    Preferably, the crossbar is formed by a subframe arranged in the floor area and a transverse support arranged in the vertical direction above the subframe. Such a design of the crossbar has proved to be advantageous since with the subframe the wheel forces of the drive wheels and with the above-mentioned crossbar, preferably a pressure support, the pressure forces, which derive from the vehicle weight and the transported load, can be easily absorbed between the two frame side beams.
    According to a preferred embodiment, the frame side beam provided with a chassis opening in the side is formed by a frame side beam arranged in the longitudinal direction of the vehicle towards the floor side and a single-angle chassis reinforcement. Such a structure of the frame side beam, in which the chassis opening is limited downwards by the frame side beam and forwards as well as upwards by the angular chassis reinforcement, enables a stable chassis frame structure, which can be based on a stiffening floor plate in the area of the assembly frame. Preferably here, both at the frame side beam and also at the chassis reinforcement, a fastening means for releasably attaching the frame side beams to the counterweight is arranged, so that an upper and a lower attachment point for attaching the frame side beams to the counterweight can be provided.
    Special advantages are obtained when the side beam forms a support bearing for the drive module. At the vehicle side, the groove side beam can be provided with a chassis opening in the side in a simple manner, a support bearing for the drive module arranged in the unit wall, for example a drive battery or an engine unit with an internal combustion engine, so that the drive module's weights can be led to this vehicle side.
    The frame side beam designed as a closed hollow body in the unit space is according to a preferred embodiment formed by two vertical wall parts arranged in the longitudinal direction of the vehicle, which form an outside and an inside of the frame side beam, a front wall and a rear wall as well as a floor wall and a cover wall. When the wall parts are formed of sheet metal pieces which are connected to each other as a welding structure, the closed hollow body can be manufactured at the frame side beam and thus a closed cavity can be produced in the frame side beam in a simple manner.
    Particularly advantageously, at least one support bearing for the drive module is designed at the inner side within the area of the unit space as hollow body-shaped frame side beams. The weight forces of the drive module arranged in the unit space, for example a drive battery or a motor unit with an internal combustion engine, can be led with corresponding support bearings at the inside of the hollow body at this vehicle side in a simple manner into the mold chassis frame.
    According to a preferred embodiment of the invention, at the inside of the area of the inner assembly frame as a hollow body, the frame side beam designed as an inlet is also arranged in the liquid container. With the design of an suction end at the inside of the hollow body beam, the suction side can easily be formed at the liquid container formed by the cavity.
    It is particularly advantageous to arrange at least one step recess on the outside of the frame side beam designed as a hollow body within the area of the unit space. By correspondingly shaping the hollow body, by extending in width, the frame side beam designed as a hollow body can be easily designed with a step recess and one or two plane steps, in order to facilitate entry and exit for a driver to the driver's seat above the unit room.
    In this case, separate footsteps can be provided or the cover wall of the hollow body can be used directly as a footstep.
    According to a preferred embodiment of the invention, the frame side beam formed in the area of the unit space as a hollow body is provided with a fixed end for a filter system arranged in the hollow body. The hollow body designed as a liquid container, preferably for hydraulic system working hydraulics, thus further accommodates the filter system with corresponding filter elements. Since, according to a preferred embodiment, even the pre-filter system is designed at the cover wall of the frame body designed as a hollow body, a particularly good accessibility to the filter system is given from the outside for service and maintenance work.
    Similar advantages can be achieved when the frame frame side beam formed in the area of the assembly space as a hollow body is provided with a lockable maintenance opening for the liquid container formed by the hollow body. When the maintenance opening is formed in the lid wall of the hollow body, a maintenance opening accessible from the outside at the top of the liquid container can be provided in a simple manner.
    With the vehicle chassis frame according to the invention, a built-in engine unit with an internal combustion engine and auxiliary unit in the unit room through the chassis opening in the side can easily provide a counterbalance truck with an internal combustion engine drive with an internal combustion engine as a power source and an electric or hydrostatic supply.
    With the vehicle chassis frame according to the invention, it is alternatively possible to install a drive battery in the unit space over the opening in the side of the chassis frame so that the co-vehicle chassis frame according to the invention can be provided with a battery electric drive with a drive battery as a drive source and an electric drive device.
    According to a particularly preferred embodiment of the invention, the vehicle chassis frame is designed as unit frames, in which by incorporating a motor unit with a single-combustion engine in the unit space a counterweight truck with propulsion of internal combustion engine types by incorporating a drive battery in the unit space can provide a counterweight. The vehicle chassis frame according to the invention enables a manufacturer of industrial trucks a low completion and manufacturing cost, with one and the same vehicle chassis frame to manufacture counterweight trucks designed with a drive of battery-electric type and of counterweight trucks with a driveline combustion engine type. Due to identical vehicle chassis frame constructions, the production of both types of counterbalanced trucks can take place on an assembly line.

The chassis reinforcement 19 delimits the chassis opening 10 on the ice side through a vertical part forwards and through a horizontal part. In the lower area the chassis opening 10 in the side is limited by the side beam 18. In the rear area the chassis reinforcement 19 and the side beam 18 are mutually provided with a respective fastening plate 20,21, which form vertically spaced fasteners B1 or B2 for detachable mounting of the frame side beam 9. Instead of two fastening plates 20, 21, a continuous fastening plate can be arranged in a channel-like manner, which extends in the vertical direction from the side beam 18 to the chassis reinforcement 19, in order to provide the fastening members B1 or B2 in a corresponding manner. The side beam 18 can be formed by a closed profile tube 18a and reinforcing longitudinal plates 18b. In the shown embodiment, the chassis reinforcement 19 consists of two plates 19a, 19b arranged laterally at a distance from each other, which are connected to each other by means of their transverse supports.
    Seen in the direction of travel, the left frame side beam 2a - as can be seen in connection with Fig. 2 - consists essentially of a hollow body 25 arranged as a closed cavity in the longitudinal direction of the vehicle, which is designed as a liquid container.
