Lever-type automobile control arm testing tool

Abstract

The invention relates to a lever-type automobile control arm testing tool which comprises an angle adjustable working table, a first fixing base, a second fixing base and a third fixing base, whereinthe first fixing base, the second fixing base and the third fixing base are mounted on the angle adjustable working table; the first fixing base and the second fixing base are connected with a controlarm; a moving plate is mounted on the third fixing base in a vertical sliding manner; a mounting base is fixed on the moving plate; a lever swinging on a horizontal plane is hinged to the mounting base; a positioning pin connected with the control arm is mounted on the lever; and a Meters hydraulic fatigue servo testing system for exerting acting force is connected with an end part, far away fromthe mounting base, of the lever. The testing tool is simple in structure, low in manufacturing cost and good in applicability, and due to additional arrangement of a lever component, the testing range of the testing tool is widened, testing equipment does not need to be changed, the testing cost can be reduced, resources can be reasonably used, and testing on automobile control arms can be facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing equipment, in particular to a lever type automobile control arm test tool. Background technique [0002] Suspension system is an important part of a modern car, which has a great influence on the ride comfort and handling stability of the car. As the guiding and force-transmitting element of the automobile suspension system, the automobile control arm transmits various forces acting on the wheels to the body, and at the same time ensures that the wheels move according to a certain trajectory. The control arm of the car elastically connects the wheel and the body of the car through a ball joint or a bush respectively. Automobile control arms should have sufficient rigidity, strength and service life. [0003] Generally, during the test of the control arm of a car, the strength test is carried out after the force is applied by the test equipment. However, due to the different mode...

Problems solved by technology

[0003] Generally, during the test of the control arm of a car, the strength test is carried out after the force is applied by the test equipment. However, due to the different models and types of cars, the corresponding strength requirements of the control arms of different models are different. When the test strength of the control arm is far beyond the test When testing the range of equipment, it is necessary to replace a large range of test equipment. As we all know, the test equipment is precision-made and expensive, which will greatly increase the test cost and cause waste of the original equipment, which is not conducive to the test of the control arm of the car.
