Automobile control arm durability test bed capable of realizing loading at any angle

Abstract

The invention discloses an automobile control arm durability test bed capable of realizing loading at any angle. The automobile control arm durability test bed comprises a busing mounting table, an actuating cylinder, a ball head fixture, an actuating cylinder front fixed support, an actuating cylinder counterforce frame, an actuating cylinder auxiliary limit mechanism and a digital display anglegauge, wherein the bushing mounting table is used for simulating a relative position of a control arm during mounting of a real automobile; the actuating cylinder is used for applying an external force at a preset angle to the control arm along the horizontal plane; one end of the ball head fixture is connected with the output end of the actuating cylinder, and the other end of the ball head fixture clamps a ball bolt connected with the control arm; the actuating cylinder front fixed support is arranged at the bottom of the front end of the actuating cylinder in a supporting manner; the actuating cylinder counterforce frame is fixedly arranged at the rear end of the actuating cylinder; and the actuating cylinder auxiliary limit mechanism is fixedly connected with the top of the front end of the actuating cylinder. The automobile control arm durability test bed disclosed by the invention can accurately and efficiently realize a load test at any angle and in the horizontal plane on the control arm, a durability test is shortened, and efficiency of the durability test is improved; the relative position of the control arm during the actual automobile assembling can reappear accurately,and reliability of the test is improved; and the automobile control arm durability test bed is simple to mount, and a durability test and a strength performance test can be performed, thereby havinggood universality.

Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a control arm endurance test bench device for loading at any angle. Background technique [0002] As a part of the chassis that bears the main longitudinal force and lateral force, the control arm's durability and strength performance are important criteria for verifying whether the design is qualified. Because the force on the Z bearing of the control arm in the vehicle coordinate system is negligible compared to the X and Y axes, the current control arm durability tests are mostly loaded in the X or Y direction of the vehicle, or loaded in the X direction first and then in the Y direction. In order to shorten the endurance test time, there is also a multi-axis loading scheme, but the test requires two or more actuators, and the required bench is more complicated. In order to reduce test resources and improve test efficiency and reliability, automobile manufacturers ...
