Anti-skid device for wheeled vehicle

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, to devices intended for increasing traction and perfecting coupling of wheeled running gear used in agriculture and forestry. Post is arranged in guide bush locked by pin and trapezoidal jaw to support hook by its lower end and, by pin top end, to support rod that enters wave-shaped groove. Said groove is made on segment disk to allow changing the proposed device by retainer from transport position into operating position, and vice versa. Said disk groove length depends upon height grouser penetration into soil hc and maximum turn angle a depends upon the number of grousers.

The invention relates to vehicles and in particular to devices to improve traction properties wheeled propulsion, and can be used in agriculture and forestry

The known device containing the axis of the housing, the associated elastic elements that are installed with the possibility of radial movement of the hooks /1/.

The closest solution to the technical essence is the device containing the axis of the rack, cheek, hook, allowing rapid transfer device from the transport position into the working position and Vice versa. One end of the axis of the fixed cheek, is attached to the drive wheel, and the other through the groove and pins locks the rack device having asymmetrically located a hook directed towards the wheel /2/.

The disadvantage of these devices is that you hook to translate in the working or transport position.

The aim of the invention is to reduce the time of the transfer device from working to transport position and Vice versa.

This objective is achieved in that the guide sleeve fixed axle and trapezoidal cheek, is hour, at the lower end of which is attached a hook, and the top of the finger, which is wave-shaped groove segment of the disk transferring device due to the release from the transport position into the working and Vice versa.

Figure 1 shows a top view of the anti-skid device in the working position, figure 2 is in the transport position, figure 3 is a side view of the operating position, figure 4 - segment disk transfer device from the transport position into the working position and Vice versa.

The device consists of axis 1, is fixed in the disk of the wheel rim nuts 2 and fixing the position of the trapezoidal cheek 3, the guide sleeve 4. On the lower end of the bar 5 fixed hook 6, and the top of the finger 7. Segment disk transfer device 8 has a wave-shaped grooves, whereby the latch 9 reaches a certain position of the disk 8 during movement of the tractor. The length of the groove segment of the disk depends on the height of the implement in the soil of a hook hCa maximum angle α of rotation from the number of hooks.

The principle of the device is as follows. When the mover on soils with low bearing capacity of the anti-skid device is in transport position (figure 2). While the traction ability of the wheel is formed due to the interaction of the tyre with the ground. Depending on the magnitude of slippage, propulsion, turning segment of the disc 8 relative to the axis of the wheel and fixing it in position by the device 9 by the transfer of a hook into the operating position. By moving the finger 7 on undulating groove of the disk , increases the height of the lifting hook 6. This gives you the opportunity to participate zacapu device in the formation of the traction ability of the wheel.

The advantage of the device lies in the fact that a slight turn of the segment of the disk is achieved by simultaneous operation of the hooks in the formation of the traction ability of the wheel, which reduces the time of the transfer device from working to transport position and Vice versa, increases efficiency and extends the range of application of the anti-skid device.
