Device for Z-shaped guide arm bench test and test method thereof

Abstract

The invention relates to a device for a Z-shaped guide arm bench test, which comprises a support bracket, a Z-shaped guide arm, a transition plate, a clamping mechanism and a servo hydraulic cylinder;the support bracket is longitudinally arranged front and back, the front end of the support bracket is connected with a Z-shaped guide arm rubber bushing, and the rear end of the support bracket is connected with the transition plate; a spherical hinge support assembly is arranged on the transition plate and connected with the rear end of the Z-shaped guide arm. A clamping mechanism is arranged in the middle of the Z-shaped guide arm to fix the middle position of the Z-shaped guide arm; a vertical guide support is arranged at one end of the clamping mechanism, the other end of the clamping mechanism is connected with the servo hydraulic cylinder, and a vertical load provided by the servo hydraulic cylinder acts on the Z-shaped guide arm. The vertical load is output by controlling the servo hydraulic cylinder and the clamping mechanism, the load borne by the Z-shaped guide arm in the vertical direction in different running processes of a vehicle is simulated, and reliable test data areprovided for structural optimization of the Z-shaped guide arm in time.

Description

technical field [0001] The invention relates to a device and a test method for a bench test of a Z-type guide arm, in particular to a bench test for a vertical load of a Z-type guide arm and a test method thereof. Background technique [0002] Air suspension is a suspension system widely used in passenger cars, trucks or trucks. It uses airbags instead of traditional leaf springs for cushioning and vibration reduction. Since the part of the airbag shock absorption system for cushioning and vibration reduction is the airbag, it is compared with The traditional vibration damping system has many advantages such as gentle cushioning, good vibration damping effect, high driving comfort, compact structure, and small footprint. [0003] The guide arm is an important functional element of the composite air suspension. On the one hand, it plays the role of connecting and guiding, and also bears part of the vertical load. The Z-shaped guide arm is arranged above the axle housing, so ...
