Embodiment Construction

[0031] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] For the three-countershaft overdrive transmission, the present invention provides a transmission lubricating and cooling system. The system adopts oil pump pressure lubrication, and realizes the lubrication of each upper lubrication point of the three-countershaft transmission through the combination of the casing oil channel and the oil pipe. At the same time, the oil A strong cooling interface is reserved at the beginning of the road, and an external forced cooling system can be connected to control the transmission oil temperature within a reasonable range, prolonging the service life of the oil product and the transmission.

[0033] Such as figure 1As shown, the three-countershaft overdrive transmission of the present invention is an 8-speed single-box three-countershaft overdrive transmission, comprising fou...

Abstract

The invention provides a transmission lubricating and cooling system, aiming at solving the problem of insufficient lubrication, reduced service life of the transmission, high risk of oil leakage, inconvenient installation, large loss of oil passage and high efficiency of the oil pump in the transmission lubrication of the existing single box three countershaft structure. lower question. The system adopts oil pump pressure lubrication, and realizes the lubrication of the upper lubrication points of the three-countershaft transmission through the combination of the casing oil passage and the oil pipe. At the same time, a strong cooling interface is reserved at the beginning of the oil passage, and a forced cooling system can be connected externally to control the transmission oil. Temperature within a reasonable range, prolong the service life of oil and transmission.

Description

technical field [0001] The invention belongs to the field of transmissions, and in particular relates to a transmission lubrication and cooling system. Background technique [0002] The 8-speed single-box three-countershaft overdrive transmission is a three-countershaft transmission with high torque (>2600N.m). Large torque transmission, wide application range. However, for three countershaft transmissions, its lubrication is a difficult point. Considering the layout of the whole vehicle's steering and shifting, transmission efficiency and temperature rise performance of the three-intermediate-shaft transmission, only one intermediate shaft is installed at the bottom, and one intermediate shaft is installed on the left and right sides above. This arrangement leads to the above It is difficult for gears and bearings to be fully lubricated through splash lubrication. At the same time, it is not possible to stir the oil to the upper gears by increasing the height of the oi...
