Problems solved by technology

The hydraulic vibration shock absorber test bench uses a hydraulic servo cylinder as the excitation force source. The disadvantages of this test bench are: high noise, high price, and relatively complicated control system, which is difficult to control
At present, the hydraulic servo system is mostly used in the shock absorber test bench to apply lateral force, the structure is complex, and oil leakage will occur

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] As shown in the figure, the test bench of the present invention includes a base, a crossbeam 2, a crossbar 8, a column, etc., a motor 1 is located above the crossbeam 2, a straight rod 4 passes through the crossbeam 2 vertically, and is connected with the motor 1 through a transmission system 3. Transmission system 3 comprises pinion, bull gear and drive belt.

[0013] During the test, the rear shock absorber 7 is installed on the test bench, and the weighing weight is loaded on the beam 9 as required. Then the straight rod 4 is driven by the motor 1, and slowly descends along the axis of the straight rod 4, and the piston rod is slowly pressed down (from the free stroke state to the minimum stroke state), and the minimum moving speed can reach 0.005m / s. The force change and displacement change in this process are transmitted ...

Abstract

The invention provides a performance test table for a rear shock absorber, which can exert lateral force to perform friction experiment researches. The test table adopts a motor (1) as a shock excitation power source, wherein the motor (1) is arranged above a test table beam (2) and connected with a straight rod (4) through a transmission system (3). The straight rod (4) vertically penetrates through the beam (2), a force sensor (5) is fixed on the straight rod (4), a displacement sensor is connected with the rear shock absorber (7), a horizontal rod (8) is vertically connected with the rear shock absorber (7), and a weight rod (9) is vertically connected with the horizontal rod (8) and downwards perpendicular to the ground. The test table adopts a mechanical excitation structure and mechanical uploading lateral force, is simple in structure and easy to control, and brings convenience to performance tests.

Description

technical field [0001] The invention relates to equipment for testing the performance of shock absorbers, in particular to a test bench for testing rear shock absorbers. Background technique [0002] The shock absorber test bench is a test equipment for testing the cushioning performance of the vehicle shock absorber during operation. The test results can directly check the performance of the shock absorber. It is an indispensable test and testing equipment for ensuring the safety and reliability of the vehicle. In the test, the standard simple harmonic motion excitation should be applied to one end of the shock absorber, and on this basis, the indicator performance and speed characteristics of the shock absorber should be detected. At present, the excitation methods of the shock absorber test bench include hydraulic excitation and mechanical excitation. The excitation is to force the shock absorber to be in a certain working state. The hydraulic-excited shock absorber test...
