Embodiment 1

[0025] Such as figure 1 A drive axle main reducer lubrication test equipment is shown, the drive axle main reducer lubrication test equipment has a bench 2 mounted on a truss 1, and the truss 1 is equipped with a front and rear inclination control mechanism, which is used to adjust The angle at which the platform 2 is inclined backwards and forwards relative to the horizontal surface, the front and rear inclination control mechanism has a first inclination adjuster 3 and a second inclination adjuster 6 located on opposite sides of the truss 1, the first inclination adjuster 3 and the second inclination adjuster 6 Both come with inclination sensors. A motor 5, a vibration sensor 9, a base 8 and a clamping plate 7 for fixing the driving axle 10 are arranged on the stand 2, and the base 8 has two supporting blocks 8-1 arranged at intervals. The motor 5 has its own speed sensor and torque sensor, and the inclination control mechanism, the motor 5, and the vibration sensor 9 are c...

Embodiment 2

[0038] The differences between this embodiment and Embodiment 1 are: A. Installing the drive axle: Open the oil guide hole A of Φ12 in the middle of the oil return channel of the main reducer bearing seat of the drive axle 10 . All the other technical features are the same as in Embodiment 1.

Abstract

The invention discloses a lubrication test method for a main speed reducer of a drive axle, and relates to the technical field of automobile manufacturing, the lubrication test method for the main speed reducer of the drive axle is characterized in that lubrication test equipment for the main speed reducer of the drive axle is used and is provided with a rack arranged on a truss, a front-back inclination angle control mechanism is arranged on the truss, and a motor and a vibration sensor are arranged on the rack; the front and back inclination angle control mechanism, the motor and the vibration sensor are in signal connection with the computer control system; the test method comprises the following steps: A, mounting the drive axle; b, debugging equipment; c, starting a test; and D, evaluating a test result. Compared with the prior art, the device can fully and accurately simulate the lubrication condition of the drive axle main speed reducer under the whole vehicle use condition, the measured data result basically represents the lubrication condition of the drive axle main speed reducer sample on the whole vehicle, the lubrication problem of the drive axle main speed reducer can be found in advance and solved in time, and the work efficiency is improved. The product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a lubrication test method for a drive axle main reducer. Background technique [0002] The drive axle is a mechanism located at the end of the drive train that can change the speed and torque from the transmission and transmit them to the drive wheels. It is generally composed of a final drive, a differential, a wheel drive, and a drive axle housing. The main reducer is used to change the transmission direction, reduce the speed, increase the torque, and ensure that the car has sufficient driving force and proper speed. Its working reliability and service life are directly related to a good lubrication state. At present, whether the main reducer of the drive axle is well lubricated is mainly judged by the following aspects: In the static state, you can see whether the lubricating oil is sufficient by opening the oil quantity detection hole of the drive axle hou...
