Abstract
The invention provides a vehicle pivot steering device. The vehicle pivot steering device comprises an oil cylinder assembly, a thrust bearing and a touch floor, wherein the oil cylinder assembly comprises at least one oil cylinder; the oil cylinder is fixed at the bottom of a vehicle; a piston rod of the oil cylinder stretches towards the lower side of the vehicle; the lower end face of the piston rod of the oil cylinder and the touch floor are connected through the thrust bearing. The oil cylinder of the oil cylinder assembly can drive the whole body of the vehicle to be separated from the ground, the vehicle can steer randomly along the rotating axis of the thrust bearing, the vehicle can complete steering or turning on a road surface or in an area with a narrower width by utilizing the vehicle pivot steering device, so that the vehicle is suitable for more road conditions.
Description
Technical field
The present invention relates to a kind of vehicle steering device, particularly a kind of device that can make vehicle pivot stud.
Background technology
At present, Vehicular turn is generally first make wheel steering, and vehicle follows turning to of wheel in travelling, but this kind of steering mode is not suitable in the width comparatively break-in of narrow lane face or tune, causes puzzlement to the daily traveling of vehicle.
Summary of the invention
Technical matters to be solved by this invention is to provide simple, the easy to operate vehicle steering device of a kind of structure.
For solving the problems of the technologies described above, the invention provides a kind of vehicle Steerring in situ device, comprise cylinder component, thrust bearing and the plate that contacts to earth, cylinder component comprises at least one oil cylinder, described oil cylinder is fixed on vehicle bottom, the piston rod of oil cylinder stretches to vehicle lower side, and the piston rod of described oil cylinder is connected by thrust bearing with contacting to earth between plate.
After adopting such structure, the oil cylinder of cylinder component can drive entire vehicle to depart from ground, vehicle can along thrust bearing pivot center optional turning, vehicle utilizes this vehicle Steerring in situ device can complete in width comparatively narrow lane face or region to turn to or reverse end for end operation, makes vehicle be suitable for more multiple road conditions.
Technology contents for a better understanding of the present invention, below by this vehicle Steerring in situ device referred to as this device.
This device cylinder component comprises several oil cylinders, all oil cylinders all synchronous workings; After adopting such structure, the stability of this device can be improved, and vehicle not easily run-off the straight.
This device contacts to earth on plate lower surface and is fixedly connected with anti-skid rubber cushion.

Detailed description of the invention
Embodiment one
As shown in Figures 1 to 4
This device comprises oil cylinder 2 assembly, thrust bearing 1 and the plate 3 that contacts to earth.
Thrust bearing 1 comprises thrust washer 11, rolling body 13 and lower thrust washer 12.
Oil cylinder 2 assembly is fixed on the center on vehicle 5 chassis, oil cylinder 2 assembly comprises four oil cylinders 2, the cylinder body 21 of four oil cylinders 2 is fixed on bottom vehicle 5, four oil cylinder 2 distributions in uniform circular, and the level height of four oil cylinder 2 placements is identical, the piston rod 22 of each oil cylinder 2 stretches on the downside of vehicle 5, piston rod 22 lower end of each oil cylinder 2 is fixed with the upper thrust washer 11 of thrust bearing 1, the lower thrust washer 12 of thrust bearing 1 and contact to earth fixing between plate 3, plate 3 lower surface of contacting to earth is fitted with anti-skid rubber cushion 4.
Oil cylinder 2 assembly can by outside fuel-feed system fuel feeding, or can by the oil piping system of vehicle 5 self to oil cylinder 2 assembly fuel feeding, four oil cylinders 2 of oil cylinder 2 assembly must accomplish synchronization telescope, when the piston rod 22 of four oil cylinders 2 is contracted to minimum stroke, the plate 3 that contacts to earth is apart from ground certain altitude; When the piston rod 22 of four oil cylinders 2 extends to range, contact to earth plate 3 and earth surface, and under the effect of oil cylinder 2, vehicle 5 by oil cylinder 2 assembly band overhead.
When vehicle 5 normally travels, the piston rod 22 of four oil cylinders 2 is contracted to minimum extended position, and the plate 3 that contacts to earth is near vehicle 5 chassis, and there is certain interval on distance ground; When vehicle 5 needs pivot turn, first vehicle 5 is stopped completely, restart four oil cylinders 2 of oil cylinder 2 assembly, the piston rod 22 of four oil cylinders 2 stretches out downwards simultaneously, drive anti-skid rubber cushion 4 and the earth surface of laminating on the plate 3 that contacts to earth, and under the effect of oil cylinder 2, vehicle 5 leaves ground gradually, chaufeur can promote vehicle 5, and vehicle 5 rotates, until vehicle 5 turns to desired location along the pivot center of thrust bearing 1, act on four oil cylinders 2, the piston rod 22 of four oil cylinders 2 is shunk, and the wheel of vehicle 5 lands again, completes vehicle 5 tune and turns to operation.
Embodiment two
As shown in Figure 5
The difference of the present embodiment and embodiment one is only: the cylinder component of the present embodiment is an oil cylinder 2a, equally also can reach the technique effect that the present invention will reach.
Above-described is only two kinds of embodiments of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
Claims (3)
