Load running-in test bench for tractor and auto chassis and running-in technology thereof

Abstract

The invention relates to the electrical and mechanical field and discloses a load running-in test bench for tractor and auto chassis and a running-in technology thereof, wherein, the running-in test bench comprises an input mechanism, a lifting mechanism, an output mechanism, a loading mechanism, a base, a hydraulic purification system and an automatic control system; the input mechanism is positioned at one end of the base, and the lifting mechanism is arranged between the input mechanism and the base; the output mechanism and the loading mechanism are positioned at the other end of the base,and the loading mechanism is positioned below the output mechanism and connected with the output mechanism through a coupling; and the automatic control system is electrically connected with the input mechanism and the loading mechanism. When a running-in test is carried out, the input mechanism, the output mechanism and the hydraulic purification system are respectively connected with a test piece of the tractor chassis or the auto chassis. The running-in technology mainly adopts the loading running-in purification technology. The running-in test bench has the beneficial effects of improvingthe quality of a whole vehicle, saving energy, time and occupied space, improving the production efficiency, reducing the ex-factory back repair rate of products and realizing the automatic control.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to a load running-in test bench for a tractor and an automobile chassis and a running-in process thereof. Background technique [0002] In the prior art, the running-in test of tractors and automobile chassis adopts the rolling-in process of random inspection of the whole vehicle. Specifically, very few prototypes are extracted from batch products, and the prototypes of the whole vehicle are rolled at full power on the roller test bench. A steel cable is fixedly pulled and loaded for running-in. This method occupies a large area, takes a long time to install, consumes a lot of fuel, and has no specific loading records. If problems are found in a small number of sampling tests, they have to be dismantled and repaired. The running-in of most tractors and automobiles is performed by the purchaser according to the manual. If you do not pay attention, the machine will be easily damaged, an...

AI Technical Summary

Problems solved by technology

[0005] 1. It occupies a large area and wastes effective production resources

[0006] 2. The test preparation time is long, the test time is long, the test disassembly and assembly are labor-intensive, and the production efficiency is low

[0007] 3. When tractors and cars are used for traction and loading, the fuel consumption is high, which wastes energy and increases costs

[0008] 4. Only sample run-in tests for tractors and cars cannot guarantee the factory quality of tractors and cars

[0009] 5. Tractors and automobiles leave the factory without running-in, the repair rate is high, which increases the cost of the enterprise and reduces the production efficiency

[0010] 6. Tractors and automobile chassis have not been loaded and run-in, hydraulically purified to process metal waste and assembly waste, and all kinds of waste left in the system will seriously damage the bearings and moving parts, affecting the service life of the equipment
