Automobile sideslip detection platform with correcting function

Abstract

The invention discloses an automobile sideslip detection platform with a correcting function. The automobile sideslip detection platform comprises a rack which is sequentially provided with an automobile correcting assembly, a sensing assembly, and a sideslip detection assembly from front to back. When an automobile is driven onto the rack, the automobile is straightened through the automobile correcting assembly; when the front steering wheels of the automobile pass through the sensing assembly, the sideslip detection assembly receives a signal of the induction assembly and moves to an initial state, and at the moment, the front steering wheels of the automobile are driven onto the sideslip detection assembly and the sideslip detection of the front steering wheels of the automobiles is completed; then the automobile is allowed to continuously and linearly advance, and when rear steering wheels of the automobile pass through the sensing assembly, the front steering wheels of the automobile are out of the sideslip detection assembly, and the sideslip detection assembly receives signals of the induction assembly and starts to move to the initial state; and when the sideslip detectionassembly returns to the initial state, the rear steering wheels of the automobile are driven onto the sideslip detection assembly, and detection of the rear steering wheels is achieved, so influenceon sideslip detection of the rear steering wheels is avoided, and sideslip detection of the automobile is more accurate.

Description

technical field [0001] The invention relates to the field of vehicle side-slip detection, in particular to a vehicle side-slip detection platform with a straightening function. Background technique [0002] The detection of the side slip of the steering wheel of the automobile is one of the important contents to ensure the safe operation of the automobile. The sideslip mentioned in this manual refers to the sideslip of the steering wheel of the car, not the overall side slip of the car when braking. Front wheel side slip refers to the mismatch between the toe and camber of the front wheels (the lateral force generated by the camber and the lateral force generated by the toe are unbalanced), causing the car to deviate left or right when driving in a straight line Phenomenon. It reflects the stability of the car in a straight line. At this time, while the steering wheel rolls forward, it will also produce a phenomenon of lateral slip, which is called sideslip. Practice has...

Problems solved by technology

The structure and working principle of the side slip table used for the inspection of double steering axles is basically the same as that of the conventional side slip table. During the inspection, the sideslip data of the front and rear steering wheels should be measured and judged separately. The front steering wheel should pass through first The side slip table detects the amount of side slip. After the front steering wheel leaves the slide plate, the slide plate spring reset on the side slip inspection table cannot immediately reset the slide plate. The slide plate will oscillate left and right in a short time, which affects the detection of the rear steering bridge and causes sideslip. Inaccurate detection

At the same time, the car enters from different directions, and the car body is tilted at different angles. In the existing technology, the vehicle is manually driven to align, and then driven into the sideslip detection platform for detection. Manual alignment requires multiple adjustments At the same time, the space in the detection area is limited, which leads to the inability of the vehicle to be completely aligned, which in turn affects the detection of the side slip of the steering wheel of the vehicle, resulting in a large error in the detected data
