Tractor chassis self-weight load type running-in purification test stand and running-in purification process thereof

Abstract

The invention discloses a tractor chassis self-weight load type running-in purification test stand and process. The tractor chassis self-weight load type running-in purification test stand comprises an input mechanism, a lifting mechanism, a rear axle installation locating mechanism, a front end installation locating mechanism, an input machine base, a rear axle machine base, a base, a hydraulic system, a hydraulic purification system and an automatic control system. The running-in purification process of the test stand is further disclosed. According to the tractor chassis self-weight load type running-in purification test stand and the running-in purification process, running-in purification can be conducted by utilizing the self-weight load of a tractor chassis transmission system under the condition that an external loading mechanism is not added, potential safety hazards inside the transmission system are removed, energy and time are saved, and production efficiency and quality of the whole vehicle are improved.

Description

technical field [0001] The patent of the present invention relates to the electromechanical field, in particular to a tractor chassis self-weight load-type running-in purification test bench and a running-in purification process thereof. Background technique [0002] Also do not utilize tractor chassis self-loading running-in process in present technology. [0003] In the current technology, the running-in test of the tractor chassis adopts the no-load running-in process of the chassis support. Specifically, the chassis shell of the tractor is supported on a platform, and a belt traction mechanism is used to drive the transmission system of the test piece for running-in. This method takes a long time to run-in, and the running-in effect is poor. During the test, problems in the assembly quality and manufacturing quality of the test piece cannot be found. And efficiency is low, can't automatic control. [0004] Because the chassis will generate a lot of processing waste dur...

AI Technical Summary

Problems solved by technology

[0005] 1. The running-in efficiency of the tractor chassis bracket type no-load test is low and the running-in effect is poor;

[0006] 2. The tractor chassis bracket type no-load test bench cannot find quality problems inside the tractor chassis, and often finds problems after sales, and the cost of returning to the factory for repair is high;

[0007] 3. There is no automatic test record for the test;

[0008] 4. It is impossible to purify the interior of the chassis, and the remaining internal processing metal waste and assembly waste will seriously damage the bearings and parts, and the hidden dangers of accidents will reduce the quality and service life of the tractor;

[0009] 5. The chassis transmission system of the tractor is run-in without running, and the running-in effect is poor, and the quality problems of the chassis transmission system cannot be found;

[0010] 6. The tractor chassis transmission system runs in dry, and there is no automatic centering and positioning adjustment during installation. The test piece is installed for a long time and the running-in time is long, and the production efficiency is low; the traction power loss is large, and the test piece is easily damaged if it is not installed in the center;

[0011] 7. The running-in test of the tractor chassis transmission system has not been carried out according to the actual operation. After the tractor leaves the factory, it has to be run-in repeatedly according to the product samples. If problems are found, the cost of returning to the factory for repair and after-sales service is high, and quality problems affect the sales market;

[0012] 8. Tractor chassis transmission system is run-in without hydraulic purification to process metal waste and assembly waste. All kinds of waste left in the chassis transmission system will seriously damage the bearings of the parts, block the lubricating oil circuit, and seriously affect the product quality.
