专利摘要:
A lifting bogie for a vehicle, comprising on both sides of the vehicle a rocker arm (4) which is journalled on a shaft (5) and in one end of which an auxiliary shaft (6) is journalled for a bogie wheel (12). When the bogie is lifted by means of a hydraulic cylinder (8) by the action of the transmission lever (7), the rocker arm (4) is pivoted so that the bogie is caused to be lifted up. In order to make the use of the lifting bogie more versatile, the transmission lever (7) is according to the invention connected to the rocker arm (4) by means of a cotter pin (18) also at a point in which the transmission lever (7) is supported on the rocker arm (4) when the bogie is being lifted. The rocker arm (4) can thereby be pivoted by means of the double-acting hydraulic cylinder (8) so that it lifts the driving shaft off the ground by means of a pendant (3) and a bogie spring (2).

This invention relates to a carriage for a vehicle.
The purpose of the invention is to facilitate vehicle maintenance.
Fig. 1 shows a lift truck where the cart is in the lowered position; Figure 2 is the same, the cart is in the raised position; fig. 3 - the same, the drive shaft is in a raised position.
The lift truck consists of a drive shaft 1 suspended on the spring of the cart 2 and wheels 3 attached to the drive shaft and driven by the drive shaft 4. The spring of the cart 2 is attached at one end to the frame 5 of the vehicle by means of conventional fastening means 6. Earring 7 The conventional construction is suspended from the opposite end of the spring of the bogie 2, and the yoke 8 is attached to the other end of the earring 7. The yoke 8 is secured with a pin on the shaft 9 of the rocker arm 8, on which the rocker arms of both sides of the vehicle wa are fixed via pivots.
With the exception of the drive shaft 4, the drive shaft 1 and the shaft 9 of the rocker arm 8, only the structural parts of the lifting carriage located on the left

side of the vehicle are visible on the figures. The right side of the vehicle is completely symmetrical. The auxiliary shaft 10 for the carriage wheel 11 is fixed by means of a pin asymmetrically with respect to the shaft 9 of the rocker arm 8 at one end of the rocker arm 8. The transmission balance bar 12 has axial rotation on the rocker arm 8 through the axle pin 13 between the shaft 9 and the auxiliary shaft 10. The center axial rotation can it is also located substantially close to the shaft 5 of the rocker arm 8, which is common in the structures of lifting carriages, which use one hydraulic cylinder located in the center.
The center of axial rotation is located in front of the shaft 9 of the yoke 8 so that the lift cylinder can occupy a more forward position. The balancer 12 of the transmission has a triangular shape, and the hydraulic cylinder 14 is attached by a trunnion to the supporting eye 15 attached to the frame 5.
The rocker 8 also has two lugs 16 with openings 17. These lugs are located on the rocker arm 8 at the point where the transmission balance bar 12 is supported by the rocker arm 8 when the carriage is raised (Figure 2). Hole 18 is made in the balancer 12 of the transmission so that the balancer 12 of the transmission can be attached to the rocker arm 8 by placing a finger 19 (in FIG. 3) through the holes 17 in the eyes 16 of the rocker arm 8 and through the holes 18 of the balance bar 12 of the power transmission.
Figure 2 shows the operation of the lift truck when the cart is in the raised position. The hydraulic cylinder 14 is in an elongated position, so that it applies force to the rocker 8 at the point of the balancer 12 of the transmission with the hole 18 and this force turns the rocker arm 8 around the shaft 9 so that the auxiliary shaft 10 and the wheel 11 of the carriage that are attached to it climbed up.
Figures 1 and 2 show the usual methods for using a trolley when it is in the lowered position (Figure 1) and in the raised position (Figure 2). Fig. 3 shows a new method of application, which is carried out by means of a lifting carriage in which the drive shaft 1 and the wheel 3 attached to it are in a raised position. The position (Fig. 3) can be achieved when the hydraulic cylinder 14 is first deduced in the direction of lifting of the carriage so that the point of the balance bar 12 of the transmission with the orifice 18 can be placed between the eyes 16 of the rocker arm 8 so that the finger 19 can be inserted into the orifice 17 into the lugs 16 and into the hole 18 in the balance bar
12 transmissions for firmly connecting the balancer 12 of the transmission to the rocker 8 also at this point. When the hydraulic cylinder 14 is then in a position in which its piston is in
0 lower point, the transmission balance bar 12 applies a force to the rocker arm 8, which causes the rocker arm 8 to rotate around the shaft 9 so that the auxiliary shaft 10 and the wheel 11 attached to it, under
5, the force is lowered down and rests on the ground, while the other end of the rocker arm 8, i.e. the end, to which the shackle 7 is attached, lifts up the end of the spring 2 of the trolley by means of a re-quarrel 2 of the trolley and the drive shaft 1
Thus, the drive shaft 1 and the wheels 3 which are attached thereto are taken off the ground. In this case, the lifting force is not as great as the force that was 55 during the lifting of the cart, because the pressure on the piston of the hydraulic cylinder 14 acts on the side of the piston rod. In practice, it is necessary that the vehicle be without load or
0 had as little load as possible when the drive shaft should be raised. Since the bogie spring, which is a leaf spring, bends in the wrong
5 direction during lifting, the spring constant of spring 1 is smaller than during normal use and therefore it is not possible to lift the drive shaft as high as the shaft of the carriage when it is lifted.
The possibilities offered by this invention in raising the drive shaft can be used in many ways. For example, the drive shaft may be pushed up for changing tires. The vehicle can be moved even when the drive shaft is stuck or detached, which facilitates servicing the vehicle, for example, in a garage. Opportunity
0 lifting the drive shaft also improves the dignity of the vehicle when it is used on rough terrain, because when driving on soft soil, the driving wheels can get stuck in the ground,
5, it becomes possible to compact the soil beneath them, raise the drive shaft so that the wheels can again rise to the surface, and the movement continues.
The lift trolley according to the invention has been described above only.
using only one specific example of the use of the invention, therefore the invention can be widely modified. In particular, if the means necessary for the invention (i.e., the means by which the transmission balance arm 7 is connected to the beam 4) can be replaced by various conventional means, one of which is the described finger, which can also be modified, for example, in such a way that the lugs are made on the transmission balance bar and are located on both sides of the same protrusion on the rocker arm. In addition, this invention can, of course, be applied to a lifting carriage comprising one transmission balancer mounted on a rocker shaft and a hydraulic cylinder mounted in the center and acting on it. The proposed design, in which the two balancers of the transmission are connected by means of pins on the yokes, has advantages in that it is more compact and more compact.
