Auxiliary vehicle steering device and vehicle

Abstract

The invention discloses an auxiliary vehicle steering device and a vehicle. The auxiliary vehicle steering device comprises a hoisting mechanism, a rotation and drive mechanism and a steering wheel. The rotation and drive mechanism is provided with a drive shaft extending in the length direction of the vehicle; the steering wheel is installed on the drive shaft to be driven to rotate by the drive shaft; the hoisting mechanism is connected between the rear of the vehicle and the rotation and drive mechanism, to control the rotation and drive mechanism to be lifted, so that the rear of the vehicle can be jacked up from the ground through the steering wheel. By applying the auxiliary vehicle steering device, when the vehicle is reversed or turns a corner, the front of the vehicle only performs a small amount of movement. Compared with the way of reversing or turning a corner in the prior art, the movement range of the whole vehicle is greatly reduced. Therefore the vehicle can be reversed or turn a corner in a relatively small space, and the vehicle is garaged and removed from the garage very conveniently.

Description

technical field [0001] The present invention relates to the field of vehicle steering systems, in particular to a vehicle auxiliary steering device, and also to a vehicle provided with the vehicle auxiliary steering system. Background technique [0002] With the improvement of living standards, people are more and more dependent on cars, the production and consumption of cars are also increasing day by day, and the roads are becoming more and more congested. The car must turn or turn around in the process of driving. [0003] Existing automobile steering gear is a kind of trapezoidal mechanism that links to each other with front axle head, and this trapezoidal mechanism links to each other with the direction operated by steering wheel through straight pull rod, makes front wheel change angle and changes the running direction of automobile by manipulating steering wheel. Because this steering device is limited by other devices, the steering angle cannot be too large. If the ...

AI Technical Summary

Problems solved by technology

Because this kind of steering device is limited by other devices, the steering angle cannot be too large. If the steering angle is too large, it will be difficult to control the car at high speed and affect safe driving; if you want to turn around, you must have a larger turning radius.

Therefore, under the condition of existing steering gear, generally can only adopt gear shifting, handle steering wheel when turning around, with the way of moving forward or reversing, the operation is quite complicated, laborious, and must have enough wide road surface or open space

In particular, large vehicles need a larger area when turning around and turning, and it is extremely inconvenient for vehicles to leave and enter the warehouse
