Abstract

The invention provides an electromagnetic damping steering device and an electromagnetic damping steering method for a vehicle, and relates to the technical field of chassis of vehicles. The electromagnetic damping steering device comprises an acquisition unit used for acquiring the speed of the vehicle and the steering wheel angle information of the vehicle in real time, an execution unit which is connected with a to-be-assembled rotating part on the vehicle, and the execution unit comprises an electromagnetic valve, an axial load push plate and a damping bearing; and the electromagnetic damping steering device further comprises a control unit which is configured to judge whether damping force needs to be output to the to-be-assembled rotating part or not according to the vehicle speed and the steering wheel angle information, and if so, the electromagnetic valve is controlled to output electromagnetic force enabling the axial load push plate to extrude the damping bearing so as to prevent the to-be-assembled rotating part from rotating around the shaft. The invention provides the electromagnetic damping steering device capable of suppressing wheel shimmy.

Description

technical field [0001] The invention relates to the field of vehicle chassis, in particular to an electromagnetic damping steering device and an electromagnetic damping steering method for vehicles. Background technique [0002] With the intensification of competition in the logistics industry, the efficiency of logistics transportation has received increasing attention from the industry. The market has higher and higher requirements for the stability of commercial vehicles at high speeds. Some commercial vehicles turn to tire assemblies and steering wheels at high speeds. The center of mass at the end deviates from the geometric center, and the wheel shakes, which affects the driving stability of the vehicle. [0003] In the prior art, the damping coefficient of the steering system is usually increased to suppress the wheel shimmy amplitude and ensure the stability of the vehicle at high speed. Specifically, by matching the damping thrust bearing on the front axle, increas...
