Wheel steering mechanism and vehicle

Abstract

The invention discloses a wheel steering mechanism and a vehicle; the wheel steering mechanism comprises an axle (3), a first wheel (1) and a second wheel (2); the first and second wheels are respectively provided with a first knckle pivot and a second knckle pivot; the first knckle pivot is provided with a first front connecting point (4) located in the front side of the axle; the second knckle pivot is provided with a second rear connecting point (5) located in the rear side of the axle; the wheel steering mechanism also comprises a first steering unit (6); the first steering unit (6) is arranged between the first front connecting point (4) and the second rear connecting point (5) so as to adjust distance of the two. The vehicle comprises the wheel steering mechanism; the first front connecting point (4) and the second rear connecting point (5) are arranged in the front side and rear side of the axle of the wheel steering mechanism; the first steering unit (6) can adjust the distance between the first front connecting point (4) and the second rear connecting point (5), so the first and second wheels can realize homodromous deflection; the wheel steering mechanism is simple in structure and easy in operation.

Description

technical field [0001] The invention relates to the field of vehicle steering systems, in particular to a wheel steering mechanism and a vehicle with the wheel steering mechanism. Background technique [0002] At present, the steering of the vehicle is realized by the steering gear. The mechanical steering system, the electric power steering system, the hydraulic power steering system, etc. all use the steering gear to realize the steering. The input shaft will transmit the steering intention from the steering wheel, and the signal will be transmitted through the sensor. To the booster motor, the booster motor and the reduction mechanism finally convert the torque into the lateral displacement thrust of the rack, and the rack drives the wheels to turn. The steering gear in the above steering mechanism is usually assembled from gear input shafts, racks, outer tie rods, steering tie rods, steering gear housings and other parts. The parts of the rack and pinion mechanism are ma...

AI Technical Summary

Problems solved by technology

The steering gear in the above steering mechanism is usually assembled from gear input shafts, racks, outer tie rods, steering tie rods, steering gear housings and other parts. The parts of the rack and pinion mechanism are manufactured with high precision and assembly precision, and the manufacturing cost is high. In order to assemble the rack and pinion structure, it is necessary to design the installation shell. The shell is large in size and heavy in weight, which makes it difficult to arrange on the vehicle chassis. The heavy mass increases the weight of the vehicle and has a negative impact on reducing the fuel consumption of the vehicle.
