Auxiliary structure for gearbox capable of lowering gearbox oil stirring power loss

Abstract

Disclosed is an auxiliary structure for a gearbox capable of lowering the gearbox oil stirring power loss. An overhead lubricant storage and distribution special-shaped plate is provided with a transverse upward protruding structure, a transverse downward sunken structure, an axial upward protruding structure and an axial downward sunken structure, a lubricant release hole is formed in the lower end of the axial downward sunken structure of the overhead lubricant storage and distribution special-shaped plate, a lubricant collecting hole is formed in the upper end of the axial upward protrudingstructure of the overhead lubricant storage and distribution special-shaped plate, the top inside a gearbox body is provided with a first liquid accumulation protrusion and a second liquid accumulation protrusion, lubricant collecting seams are arranged between the two sides of the overhead lubricant storage and distribution special-shaped plate and the inner wall of the gearbox body, and the twoaxial ends of the overhead lubricant storage and distribution special-shaped plate are provided with a first end baffle and a second end baffle. An oil storage and positioning point lubricant addingmechanism is arranged at the upper portion of the gearbox, the lubricant liquid level during working of the gearbox is lowered, and the gear oil stirring power loss is lowered.

Description

technical field [0001] The invention relates to the field of auxiliary structures for transmissions, in particular to an auxiliary structure for transmissions that can reduce the oil churning power loss of the transmission. It is suitable for automobile transmissions and mechanical transmissions, especially for multi-shaft transmissions for automobiles. Background technique [0002] General automotive transmissions have more than 2 gears, and most cars have 5 forward gears. The power loss can be divided into meshing loss, bearing loss and churning loss according to the source of generation. The lubrication method is meshing lubrication and splash lubrication. The oil power loss is the main power loss of the transmission when the lubricating oil temperature is low and the input speed is high. The reason is that generally there is only a transmission gear on the lower gear shaft, and the upper gear shaft is equipped with gear shifting parts such as a synchronizer. The purpos...

AI Technical Summary

Problems solved by technology

When the transmission is working, because part of the oil is thrown to the inner surface of the box, it cannot flow back to the oil pan along the inner surface of the box in time, the oil level of the lubricating oil needs to be increased appropriately, and the amount of oil sticking to the inner surface of the box varies between There is a big change under these working conditions. When adding lubricating oil, it must be applied according to the maximum demand. Therefore, the amount of lubricating oil applied is relatively large, and the power loss of churning oil is relatively large.

The large oil churning power loss not only reduces the transmission efficiency, but also increases the temperature of the lubricating oil, which makes the thermal stability of the lubricating oil more demanding.
