3-freedom-degree wheel clearance detection platform

Abstract

The invention relates to a 3-freedom-degree wheel clearance detection platform. The platform mainly comprises two symmetrical wheel clearance detection platforms respectively on the left and the right, a wheel clearance frame assembly (A) on each detection platform is fixed on the foundation, an upper platen framework assembly (B) are arranged on the wheel clearance frame assembly (A) to be in sliding fit with the assembly (A).One end of each piston rod fuel tank assembly is connected with the wheel clearance frame assembly (A), the other end thereof is connected with the upper platen framework assembly (B), an upper platen assembly (F) is in screw fastening with the upper platen framework assembly (B), the three fuel tanks of the three piston rod fuel tank assemblies stretch and move to drive the upper platen assembly (F) to move and rotate. The invention aims to detect the size of clearance of various parts of the wheel and take corresponding measures according to the size of the clearance to improve rideability of the automobiles. The device of the invention can detect wheel clearance at three freedom degrees, thus the detection is more accurate and intelligent and the structure of the device is simple.

Description

technical field [0001] The invention relates to a vehicle wheel gap detection device, in particular to a three-degree-of-freedom wheel gap detection device. Background technique [0002] In recent years, with the popularity of automobile safety performance testing, as an important item in the inspection station inspection items, the inspection of automobile chassis clearance is indispensable. The so-called loose clearance of the automobile chassis refers to the loose clearance between the matching parts of the automobile wheel assembly, suspension system and steering system, such as the hub bearing pair, the king pin matching pair, the ball joint fitting pair, the independent suspension pendulum Arm hinges, vertical and horizontal tie rods, steel plate lifting lugs, saddle bolts, etc., as well as the loose clearance of the drive train. The fit clearance of each part of the chassis driving system must be kept within a certain range to ensure the normal running of the car. W...

Problems solved by technology

[0007] Problems existing in the current chassis clearance testing platform: For the manual experience testing platform, since the inspection requires the inspector to stand under the oil pan of the automobile engine, the leaked oil, the dust and water falling from the chassis during vibration, and the ditch where the air does not flow The working environment is very bad

Therefore, the inspectors of various domestic inspection stations are reluctant to carry out this inspection.

Serious traffic accidents are often caused by missed inspections

The detection process cannot be automated, and the detection results lack reliability

For the microcomputer intelligent inspection platform, the platform can only move in the x and y directions, and the structure is complex

Existing vehicle chassis gap detection platform can not meet the requirements of the detection line at the same time, so it is necessary to develop a newer scientific detection system equipment
