Embodiment Construction
[0038] The present invention is described in detail below in conjunction with accompanying drawing:
[0039] The invention has the function of inspecting the loose gaps of various types of automobile chassis whose axle load mass is not greater than 10T, and can meet the requirements of the national quality supervision department and the manufacturer on the field for rapid detection of the loose gaps of the automobile chassis, thereby ensuring the safety of driving and reliability.
[0040] refer to Figure 1 to Figure 4 , the vehicle chassis loose gap detection platform is composed of a power source (hydraulic pump station) and two No. 1 motion systems E and No. 2 motion systems F with the same structure. The No. 1 motion system E or the No. 2 motion system F both consist of a drive unit I and a driven unit II. The structure of the drive unit I and the driven unit II that make up the No. 1 motion system E is exactly the same as the structure of the drive unit I and the drive...

The invention discloses an automobile chassis loose gap detection platform, which aims to overcome the problems of existing equipment structure and complex motion control. It consists of a power source and two motion systems with the same structure, and the power source and the two motion systems are connected by pipelines. Each motion system consists of a drive unit and a driven unit. The drive unit is mainly composed of the No. 1 oil cylinder, the proximity switch fixing block, the proximity switch installation plate, the proximity switch, the proximity switch sensing plate, the sensing fixing plate and the nylon sleeve of the lifting ring rod. The driven unit is mainly composed of a lower plate and an upper plate. The lower plate is horizontally fixed on the foundation, the upper plate is stacked on the lower plate, and the lower left corner of the upper plate and the lower plate is connected by the upper plate hinge sleeve, hinge shaft cover, hinge nylon bushing, hinge nylon bushing and anchor bolts. , the lower working surface at the lower right corner of the upper plate is rotatably connected with the lifting lug at one end of No. 1 oil cylinder, the lower working surface at the upper right corner of the lower plate is rotatably connected with the lifting lug at the other end of No. 1 oil cylinder, the oil inlet and outlet of No. 1 oil cylinder and the power source pipe road connection.
Description
technical field [0001] The invention relates to a detection device applied to automobiles, more specifically, it relates to a detection platform for looseness and clearance of automobile chassis. Background technique [0002] 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. Whether any of the gaps are too large or poorly lubricated, it will lead to a decrease in the driving performance of the car, deterioration of handling stability, driving s...
