    description
    TECHNICAL AREA
    The technical solution relates to the field of devices for preventing slipping, in particular of devices for preventing slippage for vehicle wheels.
    STATE OF THE ART
    Efforts have long been made to improve the traction of vehicle wheels under harsh winter or off-road conditions using various chains, Ra-kes, pedals, etc. For example, U.S. Patent 768,495 to 1904 shows the use of hand-operable chains for this purpose. Fast switchable chains are known from United States Patent 1150148 of 1913, which in principle is still produced today under the name OnSpot. They are mainly used for trucks, emergency vehicles and maintenance vehicles.
    Slip prevention devices are also known, which are attachable to a vehicle tire and which, if necessary, are switched, i. E. be brought into the working position. These are pneumatic systems which are described, for example, in WO 0172533, EP 0930980, WO 2004012949 or mechanical systems which are set out, for example, in WO 2011050218 or DE 102 010 011 339. These anti-skid devices have different characteristics and their complexity, actual utility, reliability and cost are different. TECHNICAL SOLUTION PROBLEM: The object of the technical solution is to produce a device for preventing slippage on a cartwheel, which enables remote balanced control with respect to operating parameters in terms of simplicity, reliability, practicality and controllability.
    This object is achieved by a device for preventing slipping for vehicle wheels, which is attachable according to the technical solution to a wheel disc, characterized in that it comprises a support member which is attachable to the wheel disc, what several radially arranged arms through Joints are adapted, whose axes of rotation are parallel to the plane of the disc and perpendicular to the radial direction, each arm is provided with a traction surface which is adjacent in the working position on the tire peripheral portion and pressed in the rest position towards the tire center.
    According to the first embodiment, each arm is attached to two joints at two joints by two cranks, with which the arm is pivotally connected at two points to a support element, wherein the pivot axes, which are preferably in the same plane perpendicular to the wheel axis, are radially offset from each other, and the arm and the cranks generate a parallelogram.
    According to the second embodiment, each arm is attached to a support member at a hinge.
    The anti-skid device may be provided with at least one wireless remote controlled electric motor with batteries for arm position control.
    It is also possible to provide the device for preventing slipping with a loading and diagnostic system which is connected by a control module.
    The electric motor may be arranged in the wheel axle.
    An annular locking with peripheral lugs is attached to the output shaft of the electric motor, wherein the number of lugs corresponds to the number of arms. In the rest position, the arms extend behind the lugs, and when the lock rotates, the arms are pushed by a spring force into the working position.
    The springs are advantageously of the torsion type and arranged around the pivot axes of one of the cranks.
    A spiral screw, which engages in a toothed segment formed on a crank, can be arranged on the output shaft of the electric motor.
    It is also possible to assign each arm an electric motor with an output shaft coaxial with the axis of one of the Armanbringungsgelenke on a support element.
    In order to prevent buckling of the parallelogram at the dead center, a crank should be assigned a biased against the arm elastic element.
    In order to ensure correct operation, the inner cranks with certain geometrical proportions may have a different length than the outer cranks.
    DESCRIPTION OF THE DRAWING
    Examples of embodiments of anti-slip devices for vehicle wheels according to the technical solution are shown in the attached drawing, in which Figure 1 is a wheel-mounted anti-skid device, Figure 2 is the same device in the working position, Figure 3 is the second embodiment of slide-mounted anti-skid devices, Figure 4 is the device of Figure 3 in the working position, Figure 5 is the third embodiment of slip-mounted anti-skid devices, Figure 6 is the device 5 is in the working position and FIGS. 7A-7D show schematically several phases of the arm ejection according to the first embodiment to the working position.
    EMBODIMENTS
    The slip prevention device comprises a support member 1 which is formed as a plate in this case. This support member 1 is in a known manner from the Au ßenseite mounted on a Fahrzeugradscheibe 12, as set out, for example, in the Czechoslovakian patent CZ 280 219. Several radially arranged arms 2 are mounted at the same angular distance on the support element 1. In this case, there are four arms, of which only one is shown in FIGS. 1 and 2 for reasons of clarity. Each arm 2 is pivoted by two cranks 3 and 4 at joints 13. The axes of the joints 13 are parallel to the plane of the disc 12, they are perpendicular to the radial direction, being offset from each other in the radial direction, and they are in this case in the same plane. Also, the points of the pivotal connection of the arm 2 with the cranks 3, 4 are spaced apart. The inner crank 3, whose axis of rotation is closer to the wheel axis, is the inner crank, and the second crank 4 is the outer crank. This arrangement makes each arm 2 and its cranks 3, 4 a parallelogram. The arms 2 are provided at the ends with traction surfaces 5, which in the working position (Figure 2) adjoin the circumference of a tire, and are retracted in the rest position towards the wheel center (Figure 1).
    A specific design of the cranks 3, 4 is determined by the requirement of reliable operation over the useful life of the device with respect to the operating conditions. Therefore, the outer crank 4 is provided in duplicate according to this embodiment. The inner crank 3 is then arranged between the double sections of the outer crank 4.
    The device for preventing slipping further has a wireless remote-controlled electric motor 7 with batteries, which are arranged on the support element 1. The electric motor 7 is located in the wheel axle.
    According to the first embodiment (Figures 1 and 2), an annular lock 8 is mounted with radial projections 9 on the circumference of the output shaft of the electric motor 7. The number of lugs 9 is equal to the number of arms 2, which are fixed in the rest position behind the approaches 9 9. After a control signal from the electric motor 7 has been sent, the electric motor rotates the lock 8. This releases the arms 2, which are then moved to the working position by the force of torsion springs 6 (FIG. 2). The springs 6 are arranged about the axis of the joint 13 of one of the cranks 3 or 4. As a result, the arms 2 with the traction surfaces 5 make a curved movement along a tire side, which is given by the parallelogram. In the final phase of this movement, the traction surfaces 5 adjoin the tire circumference, and the arms 2 abut laterally on the tire side. The arms 2 can then be adapted again to the working position while driving. According to this embodiment, the arms 2 are manually returned to the rest position. The arms 2 move against the force of the spring 6 until the latches 8 snap behind the lugs 9.
    The second embodiment (Figs. 3 and 4) differs in the control of the movement of the arms 2 from the aforementioned first embodiment. The movement of the arms 2, both from the rest position to the working position and from the working position to the rest position, is ensured entirely by an electric motor 7. The electric motor 7 is therefore stronger in this case, and it is appropriate to provide a rechargeable battery unit. A spiral screw 10, which engages in a formed as part of one of the cranks 3 or 4 toothed segment 11 is attached to the output shaft of the electric motor 7. The movement of the arms 2 is wirelessly controlled by electric signals output from the electric motor 7. According to this embodiment, it is appropriate to assign a spring (not shown) biased against the arm 2 to the inner crank 3 to prevent buckling of the parallelogram at the dead centers in which the cranks 3 and 4 are oriented in parallel.
    The length of the cranks 3 and 4 and the position of their axes of rotation are given by the geometric relationships of the wheel, the disc and the tire. The length of the inner cranks 3 may differ from the length of the outer cranks 4. As a result, an optimal fit of the traction surfaces 5 on the tire circumference and the arms 2 on the tire side is always achieved.
    Other control systems than those described above may be used to move the parallelogram, such as pneumatic control systems.
    FIGS. 7A-7D schematically show several parallelogram positions. In FIGS. 7B and 7C, the arms 2 with traction surfaces 5 bypass one side of a tire, not shown, and in FIG. 7D the traction surfaces 5 adjoin the tire circumference (working position).
    According to the third embodiment (Figures 5 and 6), each arm 2 is attached to a single joint 13. In this case, perform the arms 2 with traction surfaces 5 a rotational movement. This arrangement is suitable for wheels with tires with a low profile. According to this embodiment, it is also appropriate to provide each arm 2 with an electric motor 7. Electric motors 7 are then arranged coaxially with the axes of joints 13.
    It is appropriate to provide slip prevention devices with a diagnostic system connected to a control module. This is not shown in the illustration.
    For safety reasons, it is appropriate to provide the device with a cover, not shown. 3.11
