Problems solved by technology
Therefore, the impact load generated by engineering vehicles during shoveling and transportation operations on various slope environments and uneven road surfaces restricts the various performances of the drive train, and has great impact on the structural design, processing technology, assembly process and lubrication of the drive train. method posed great difficulties
At present, the conventional maximum static load test and fatigue test cannot examine the instantaneous impact performance of the drive train in this time domain

The invention discloses an impact property detecting and analyzing system of a transmission system of an engineering vehicle. Three working table adjusting mechanisms and a ball pair fixing seat are arranged at the bottoms of four corners of a tilting working table, and the three working table adjusting mechanisms enable the tilting working table to be in different tilting directions and angles; two loading spectrum generating mechanisms are arranged on the tilting working table, and two connected adjusting support frames are positioned between the two loading spectrum generating mechanisms and are used for supporting the transmission system of the engineering vehicle; and the output end of a torque transmitter is connected with the input end of a transmission shaft of the engineering vehicle, the output end of a servo motor is connected with the input end of the torque transmitter, the servo motor transmits torques to the transmission system of the engineering vehicle through the torque transmitter, and the two loading spectrum generating mechanisms are connected with the transmission system of the engineering vehicle to apply impact loads to the transmission system of the engineering vehicle. The system can test each property index of the impact-resistant load of the transmission system to provide data for the design of the transmission system of the engineering vehicle.
Description
technical field [0001] The invention relates to a test device, in particular to a system for detecting and analyzing the impact performance of the drive train of an engineering vehicle. Background technique [0002] The working environment of construction vehicles is harsh, the road surface of the work site is often a variety of ramps and uneven ground, and the work objects are complex and changeable. When engineering vehicles perform tasks such as digging, transporting, and loading complex and changeable objects on such ramps and uneven roads, or when they brake suddenly, impact loads will be frequently generated in the drive train, thereby The main drive train components such as hydraulic torque converter, gearbox and drive axle are subjected to large and complex forces, which deteriorate their technical condition, often leading to abnormal noise, oil leakage, overheating and early failure of mechanical parts, which seriously It affects the effective working performance a...
