The invention relates to a hydraulic-vibration inclinable low temperature testing table for an electric power closed-loop single gear box. An inclinable testing table body for the power closed-loop single gear box, a transverse vibration device, a low temperature testing system, a first gantry framework integral stand column and a second gantry framework integral stand column are fixed on vibration-isolation T-shaped groove iron casting platform; a first gantry vertical hanging vibration system and a second gantry vertical hanging vibration system are fixed on the first gantry framework integral stand column and the second gantry framework integral stand column respectively; the low temperature testing system comprises a low temperature cooling system, a heat-insulation cooling circulating flexible pipeline and axial-flow machine assembling body and a low temperature test wooden cold-air circulating box; the low temperature cooling system provides cold air for the low temperature test wooden cold-air circulating box in a circulating mode through the heat-insulation cooling circulating flexible pipeline and axial-flow machine assembling body. The problems that in the prior art, when a tested gear box is disassembled and installed on different testing tables for tests, the tests are cumbersome, and testing results are inaccurate are solved.
Description
technical field [0001] The invention relates to a test platform for detecting parameters of a transmission system of a rail vehicle, in particular to an electric power power closed-loop single gear box hydraulically excited tiltable low-temperature test platform. Background technique [0002] At present, the development of my country's high-speed train technology is advancing by leaps and bounds. The maximum operating speed of the new generation of EMUs has reached 380km / h, and the maximum test speed of the newly developed EMUs is close to 600km / h. The increase of train speed and vehicle axle load has aggravated the impact vibration between the wheel set and the track, and the ride comfort, safety and stability of rail vehicles have become increasingly prominent. As an important part of the rail vehicle bogie, the gearbox is responsible for transmitting the power of the train to the wheelset, and its performance directly affects the performance of the bogie and even the enti...
