Hydraulic variable-diameter racing car steering wheel based on linear speed matching driving

Abstract

The invention discloses a hydraulic variable-diameter racing car steering wheel based on linear speed matching driving, and relates to the technical field of car steering components. A first orientation hydraulic cavity and a second orientation hydraulic cavity which are symmetrically distributed relative to a steering main shaft are formed in an internal hydraulic pipe; main adjusting shaft rodsare independently arranged on the peripheries of the first orientation hydraulic cavity and the second orientation hydraulic cavity of the inner hydraulic pipe; side hydraulic pipes are fixedly connected to the two sides of the inner hydraulic pipe; second auxiliary hydraulic shaft rods which are independently driven are arranged on the two sides of each side hydraulic pipe. According to the hydraulic variable-diameter racing car steering wheel based on linear speed matching driving of the invention, hydraulic drive regulation matching with the vehicle speed is carried out, and the handheld radiuses of peripheral handle bodies are finely adjusted, so that a control mechanism for reverse proportional adjustment with the vehicle speed can be formed, so that large deviation of a vehicle caused by the micro-motion of the steering wheel is reduced; and the phenomenon that handles on the inner side and the outer side of the steering wheel are greatly asymmetric in a high-speed steering process is reduced, and the steering smoothness and safety of a racing driver rapidly rotating the steering wheel are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile steering components, in particular to a hydraulic variable-diameter racing steering wheel based on linear speed matching drive. Background technique [0002] During the driving process of the car, it is necessary to change its driving direction frequently according to the will of the driver, which is the so-called car steering. As far as wheeled vehicles are concerned, the method to realize the steering of the vehicle is that the driver deflects the wheels on the steering bridge of the vehicle at a certain angle relative to the longitudinal axis of the vehicle through a set of special mechanisms. When the car is running in a straight line, the steering wheel is often affected by the lateral disturbance force of the road surface, and automatically deflects to change the driving direction. At this time, the driver can also use this mechanism to deflect the steering wheel in the opposite directio...

Problems solved by technology

[0003] In the process of high-speed driving of the vehicle, such as driving on the highway, or in the high-speed driving regulations of the racing car in the racing competition, the speed of the vehicle is fast, and a slight deflection of the steering wheel may cause the driving of the entire vehicle to deviate.

However, in the existing technologies for preventing excessive deviation of the vehicle under high-speed driving, the hydraulic steering force in the vehicle steering system is adjusted to a relatively high pressure, so that although the steering system does not have a large deviation when the vehicle is running at high speed, However, the steering force of the steering wheel will be too large, which is only suitable for the micro-steering adjustment of the high-speed section of the family car; while the racing car needs fast steering wheel steering adjustment in the racing field, the existing vehicle stability steering system is obviously not suitable for the steering operation of the racing car
