Abstract

The invention relates to the technical field of an automobile steering system and discloses an automobile steering system test device. The test device comprises a basic framework, a wheel lifting device, a steering input device and a front axle installation support, wherein the wheel lifting device, the steering input device and the front axle installation support are arranged on the basic framework. When a lifting machine lifts a lifting framework until load of a steering wheel reaches a preset position, a transmission shaft of a driving device drives a steering column to rotate, and a torqueangle sensor arranged on the transmission shaft obtains torque input to the steering column by the driving device; and meanwhile, by enabling the lower end surface of a torque sensor to be connectedto a second installation plate, static friction torque generated between the steering wheel and a lifting tray is obtained through the torque sensor, so that a relation curve between steering disc input torque and steering wheel aligning torque is obtained, and relation between the steering disc input torque and the steering wheel aligning torque is known so as to realize reasonable setting of parameters of the steering disc input torque and the steering wheel aligning torque and the like.

Description

technical field [0001] The invention relates to the technical field of an automobile steering system, in particular to a test device for an automobile steering system. Background technique [0002] At present, when a car is running, it usually needs to change its driving direction according to the driver's operation, so as to realize the steering of the car. For wheeled vehicles, the method for realizing the steering of the vehicle is generally that the driver deflects the steering wheel on the front axle of the vehicle by a certain angle relative to the longitudinal axis of the vehicle through the vehicle steering system. In addition, when the car is driving straight, the steering wheel will also be automatically deflected by the lateral disturbance force of the road surface, resulting in a change in the driving direction of the car. Therefore, the driver also needs to use the car steering system to turn the steering wheel in the opposite direction. Deflection to return th...
