Splash lubrication experimental method for hybrid power transmission

Abstract

The invention discloses a splash lubrication experiment method for a hybrid power transmission, which comprises the following steps that: S1, the structure and the size of a transmission shell are imitated, a transmission shell is manufactured by utilizing a transparent material, and assembly parts such as a gear shaft, a clutch and the like are installed in the transparent transmission shell; s2, bearing holes of a transmission generator input shaft, an engine input shaft, a driving motor input shaft and the like are sealed, and only a transmission differential mechanism output shaft is reserved; s3, a motor is connected to the transmission differential mechanism output shaft; s4, the transmission and the motor are installed on a test bed together; s5, a certain amount of lubricating oil is injected into the transmission through the oil injection hole; s6, the motor is started, and a related shaft system is driven according to a set rate; and S7, a lubrication experiment is realized under pure electric and hybrid working conditions through the opening and closing of a clutch. The occupied space is reduced, the complexity of an experiment device and control is reduced, meanwhile, the manufacturing cost is reduced, and vibration and noise are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of hybrid power systems of new energy vehicles, and in particular relates to a splash lubrication experiment method of a hybrid transmission. Background technique [0002] As an important part of the vehicle transmission system, the transmission directly affects the performance of the vehicle in many aspects such as power, economy, maneuverability, transmission stability and transmission efficiency. The primary function of the automobile transmission is to change the torque and speed of the wheels by changing the transmission ratio of the automobile to meet the different requirements of the traction force and speed of the driving wheels under different working conditions such as starting, accelerating, driving, and uphill and downhill. Work under favorable conditions. [0003] At present, most of the transmissions still adopt the gear type. The gear type transmission mainly depends on the different transmis...

AI Technical Summary

Problems solved by technology

[0009] 1. After the engine and drive motor are installed, they occupy a large space, which hinders the observation of the internal lubrication of the transmission;

[0010] 2. Both the driving motor and the engine need cooling pipelines to achieve cooling, which increases the complexity of the experimental device and control;

[0012] 4. The engine and the drive motor will produce a large vibration, especially the engine, the vibration noise is relatively large, resulting in a poor experimental environment, and the vibration will bring some problems to the transparent shell and the internal gear shaft
