The invention discloses a car steering system test-bed mounting adjustment system. The system comprises a test-bed, a steering axis adjusting device, a redirector adjusting device, a vertical loading axis adjusting device arranged on the left and right sides below the redirector and a lateral loading axis adjusting device arranged on the left and right sides of the redirector. The invention can realize the spherical hinge pre-positioning of the connection of the steering axis and the steering system, then on the basis of the result, the steering axis adjusting device is adopted to adjust and set the angle of inclination of the steering axis, the vertical loading axis adjusting device is used to adjust the distance between the two vertical loading axes, the lateral loading axis adjusting device is used to adjust the positions of the BELL mechanism and the lateral loading axis on the two sides to realize the spherical hinge positioning five-axis linkage so that the fast installing and positioning of the BELL mechanism and the overall car steering system can be realized for one time, the parameters of mechanisms in the same steering system to be tested can be fast adjusted and the performances on different conditions can be analyzed and verified. When the system is used to test the redirectors of different cars, the installation mode of the redirector is ensure to be as similar as possible with the loading mode, and the system has the advantage of wide universality.
Description
technical field [0001] The invention relates to an automobile test bench, in particular to an installation and adjustment system for an automobile steering train test bench. Background technique [0002] Automobile steering system is an important part to ensure that the automobile turns or keeps stable according to the will of the driver, and its performance directly affects the safety and maneuverability of the automobile. Therefore, the performance test of the automobile steering system is of great significance to the determination of the design parameters of the steering gear and the reliability of the performance of the steering gear. Existing test bench products are for component testing of mechanical rack and pinion steering gear, hydraulic power steering gear and electric power steering gear respectively. There is no steering gear test bench common to all three, nor is there a test bench for steering system. The existing steering gear assembly test bench is for the t...
