Portable digital display automotive suspension clearance test stand calibrating apparatus

Abstract

The invention discloses a detecting device for portable digital display vehicle suspension clearance test table so as to provide a detecting device for portable digital display suspension clearance test table to fulfill blank of device of this aspect. The detecting device is composed of a digital meter (1), an outer layer gripper part (2) and an inner layer gripper part (3). The inner layer gripper part (3) is mounted in the outer layer gripper part (2), connected actively to the outer layer gripper part (2). The outer layer gripper part (2) is fixed on groundwork. Lower surface of the inner layer rectangular frame (13) in the inner layer gripper part (3) is placed on upper surface of the vehicle suspension clearance test table. The digital meter (1) is mounted outside of the outer layer gripper part (2). An interface of the digital meter (1) is connected to an interface line of a force sensor (9) and a displacement sensor (10) mounted on the inner layer gripper part (3). The invention is applied to synchronous detection of force and displacement of the vehicle suspension clearance test table.

Description

technical field [0001] The invention relates to a test device for testing equipment used in the automotive field, more specifically, to a test device for a portable digital display vehicle suspension gap test bench. Background technique [0002] The so-called suspension gap refers to the gap between the matching parts of the automobile suspension system and the steering system, such as the hub bearing pair, the kingpin fitting pair, the ball joint fitting pair, the independent suspension swing arm hinge, the vertical and horizontal tie rod, the steel plate Fitting clearances at lugs, saddle bolts, etc. [0003] Suspension clearance must be kept within a certain range to ensure the normal driving of the car. Whether the suspension clearance is too large or the lubrication is poor, it will lead to the decline of the driving performance of the car, the deterioration of the handling stability, the driving swing, the accelerated wear of the tires and suspension parts, the steeri...

AI Technical Summary

Problems solved by technology

However, due to the actual application of the equipment, the force and displacement are transmitted to the wheels on the platform of the suspension clearance test bench through a series of complex mechanical devices, and the force and displacement sensors of the suspension clearance test bench measure only mechanical The signal at the beginning of the actuator of the device ignores the influence of the transmission process of the intermediate mechanical device on the accuracy. Therefore, only by simulating the resistance exerted by the automobile suspension on the terminal of the actuator at the end of the actuator of the mechanical device can a comprehensive suspension clearance test bench be realized. roll correctly

[0005] At present, there is no device for comprehensive verification of the automobile suspension clearance test bench
