Gearbox fatigue test device

Abstract

The invention discloses a gearbox fatigue test device, comprising a test box, wherein a drive motor is fixedly mounted on a motor base; a connection rod is fixedly mounted on the drive motor through utilization of a shaft coupler; cam disks are fixedly mounted at two ends of a belt wheel connection rod; one end of an eccentric wheel connection rod away from an eccentric shaft is movably mounted ona gearbox fixing base; shaking springs are fixedly mounted at the bottom of the test box; the connection rod is also fixedly connected with a rotation sleeve through utilization of the shaft coupler;the gearbox fixing base is movably mounted in a translation track set in the test box; a collision base is movably mounted in the translation track; and a collision plate is fixedly mounted at one end of extrusion springs way from the collision base. According to the device, bumping feeling generated when a car passes through an uneven road surface can be simulated, a test result is effectively guaranteed to be relatively close to a practical driving state, moreover, stability of a gearbox can be tested under the condition that the gearbox is continuously collided, and the test result is relatively close to practical working condition.

Description

technical field [0001] The invention relates to the technical field of gearbox experiment devices, in particular to a gearbox fatigue test device. Background technique [0002] In the prior art, the application number is "CN201821716579.1", a test bench that can quickly clamp the gearbox, including a test platform, a motor, a torque sensor and a clutch. The clutch output shaft of the clutch is connected to the transmission through the third coupling. The power input shaft of the box is connected, the gearbox is fixed with the connecting seat, the connecting seat is formed with a rectangular hole, and a rectangular groove is formed on the upper side wall and the lower side wall of the rectangular hole, and the rectangular hole is inserted into the rectangular boss of the fixing seat In addition, the fixed seat also includes a bottom plate fixed on the clutch, and two "T"-shaped lock pins are sleeved in the "ten"-shaped groove of the rectangular boss, and the convex part of th...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned test bench that can quickly clamp the gearbox still has obvious defects during use: 1. The above-mentioned device can only perform static tests, and it is difficult to simulate road conditions for dynamic tests, and the test accuracy is low; 2. The above device cannot be crash tested and cannot simulate the stability of the gearbox under different conditions
