Abstract

The invention relates to a transmission box reverse gear bearing hole lubricating oil duct structure which comprises a reverse gear bearing hole formed in a right box of a transmission and a reverse gear bearing matched with the reverse gear bearing hole and further comprises a lubricating oil pipe arranged in the right box and an oil pipe cap connected with the lower end of the lubricating oil pipe. The transmission box reverse gear bearing hole lubricating oil duct structure is characterized in that the lower end of the lubricating oil pipe is positioned near the reverse gear bearing hole; the right box is provided with a cast oil duct at a position corresponding to the lower end of the lubricating oil pipe, and the upper end of the cast oil duct is provided with an oil duct connector; the oil pipe cap is in interference fit with the oil duct connector; a sunken structure is arranged on the right box between the lower end of the lubricating oil pipe and the reverse gear bearing hole, and an engine oil filling channel is arranged in the sunken structure; and one end of the engine oil filling channel communicates with the lower end of the cast oil channel, and the other end of the engine oil filling channel communicates with the reverse gear bearing hole. The internal space of a gearbox is not occupied, the modal of a box body can be improved, the machining workload can be reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an automobile transmission, in particular to a lubricating oil passage structure in a reverse gear bearing hole of a transmission. Background technique [0002] Transmissions with light weight, small size, high power and long life have become the main development trend of the market, and the lubrication effect of the transmission directly affects the performance of the transmission. Therefore, the design of transmission lubricating oil passage becomes one of the important parts of transmission design. In order to meet the requirements of light weight, small size and long life, an 8-speed automatic transmission has a separate reverse gear shaft; the reverse gear bearing hole is arranged on the transmission case. In order to ensure the normal operation of the reverse gear bearing, the lubricating oil needs to be The reverse gear bearing is lubricated and cooled. According to the conclusion of CAE analysis, splash lubrication ca...
