Steering system and independent suspension wheel type overload vehicle

Abstract

The invention relates to a steering system and an independent suspension wheel type overload vehicle. The steering system comprises a steering mechanism and a steering hydraulic power assisted system, wherein the steering mechanism is used for providing steering force for wheels; the steering hydraulic power assisted system is used for providing the wheels with steering assisted power for overcoming the steering resisting moment from the ground. As the steering mechanism is used for providing the steering force for the wheels and the steering hydraulic power assisted system is used for providing the wheels with the steering assisted power for overcoming the steering resisting moment from the ground, compared with a steering system only depending on torque output by a steering gear or only depending on torque output by the steering gear and a steering power assisted follower, the steering system can effectively overcome the steering resisting moment from the ground, and the vehicle can have the steering capacity at various sites.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a steering system and an independent suspension wheeled heavy-duty vehicle using the steering system. Background technique [0002] At present, most wheeled heavy-duty vehicles use leaf springs and oil-pneumatic suspensions as non-independent suspensions of elastic elements. The left and right wheels of the non-independent suspension and their tires are fastened on the same axle, and the The body is connected. In this way, the impact load transmitted from the ground to the vehicle body cannot be effectively attenuated by the suspension, and the up and down jump of the two wheels can make the vehicle body tilt. [0003] The independent suspension vehicle has a small unsprung weight, and the impact load received by the suspension and transmitted to the body is relatively small, which is conducive to improving the ride comfort of the vehicle and the grounding performance of the...

AI Technical Summary

Problems solved by technology

[0005] Some of the existing disconnected steering trapezoidal mechanisms only rely on the torque output by one or two steering gears to drive the steering of the left / right wheels of the vehicle, and some rely on the torque provided by a steering gear and a steering assist follower. For the steering of the left / right wheels of the vehicle, the above-mentioned disconnected steering trapezoidal mechanism that only relies on the torque output by the steering gear or the torque output by the steering gear and the steering assist follower to overcome the steering resistance distance from the ground can only It is suitable for mobile off-road vehicles with light overall weight, and there is no relatively complete steering system for wheeled heavy-duty vehicles that require high off-road performance.
