Technical Field

The invention belongs to the technical field of automobile steering parts, and particularly relates to a hydraulic variable-diameter racing car steering wheel based on linear speed matching driving.

Background

During the driving process of the automobile, the driving direction of the automobile needs to be changed frequently according to the intention of a driver, namely the automobile steering. In the case of wheeled vehicles, steering is achieved by a driver by means of a set of special mechanisms which deflect the wheels of the steering axle of the vehicle at a certain angle relative to the longitudinal axis of the vehicle. When the automobile runs in a straight line, the steering wheel is always subjected to the action of lateral interference force on the road surface and automatically deflects to change the running direction. In this case, the driver can also turn the steered wheels in the opposite direction by using the mechanism, so that the vehicle can return to the original driving direction. The special mechanism for changing or restoring the driving direction of the automobile is called an automobile steering system.

During high speed driving of the vehicle, such as driving on a highway or during high speed driving regulations in a racing car race, the vehicle speed is high, and the steering wheel is slightly deflected, so that the driving of the whole vehicle is possibly deviated. In the existing technology for preventing the vehicle from generating excessive deflection during high-speed running, the hydraulic steering force in a steering system of the vehicle is regulated to be larger pressure, so that the steering system cannot generate larger deflection during high-speed running of the vehicle, but the steering force of a steering wheel is too large, and the steering wheel is only suitable for micro-steering regulation of a high-speed road section of a family car; while racing cars require rapid steering wheel steering adjustments in the race car field, existing vehicle stability steering systems are clearly unsuitable for racing car steering operations.
