Abstract

The invention provides a vehicle steering mechanism testing table which is characterized in that it comprises a foundation, steering simulation devices, a rack fixing supporting block combination and a height-adjustable inclined table; between the two steering simulation devices is equipped with steering rack bars; on the steering simulation device is equipped with a linear offset sensor and an angle rotation sensor that are connected with the hydraulic cylinder; the torsion sensor and the hydraulic motor are installed on the test inclined table; the gas-pressure system and the hydraulic system are connected with the hydraulic motor. The invention employs five-axle testing system to simulate the running behavior of the steering device; each axle can simulate the running resistance and road situation in different conditions; the sensors measure and analyze the test data needed by each axle.

Description

technical field [0001] The invention relates to automobile test equipment, in particular to a measuring device for testing the full rotation angle of an input shaft, transmission ratio characteristics, transmission clearance characteristics, transmission efficiency characteristics, rotational torque and rigidity of a steering system of a steering system of an automobile. Background technique [0002] The automobile steering system is an important part to ensure that the automobile can be steered or kept stable according to the driver's will, and its performance directly affects the safety and maneuverability of the automobile. Therefore, the performance test of the automobile steering system is an important inspection process before the steering gear leaves the factory, and it is a key step to ensure the quality of the steering gear product. The existing steering gear assembly test bench is a three-axis performance test, which cannot completely simulate the actual road condi...
