Lubrication structure of dual clutch hybrid transmission

Abstract

The invention relates to the field of vehicle transmissions, and aims to provide a double-clutch hybrid power transmission lubrication structure. The double-clutch hybrid power transmission lubrication structure comprises a transmission shell, a clutch shell provided with a lubrication oil way on the side wall, and an oil pump connected with the clutch shell; an outlet of the oil pump is communicated with an inlet of the lubrication oil way; a vertical intermediate shaft is provided with a transmission gear at the upper end, and is pivoted with the transmission shell; a motor is mounted at the upper part of the inner side of the transmission shell; a motor gear is connected with an output shaft of the motor; a transition gear is respectively engaged with the motor gear and the transmission gear; a lubrication branch way is connected with the lubrication oil way by one end; a middle hole is formed in the vertical intermediate shaft; and the other end of the lubrication branch way penetrates through the middle hole to extend out of the upper end of the vertical intermediate shaft. In the double-clutch hybrid power transmission lubrication structure, transmission oil can reach the motor gear, the transition gear and related rolling needle bearing needing to be lubricated for lubrication, so that the lubrication effect is better.

Description

technical field [0001] The invention relates to the field of automobile transmissions, in particular to a double-clutch hybrid transmission lubrication structure. Background technique [0002] Automobile transmissions change speed by changing the transmission ratio of gears; automobile manual transmissions are lubricated by splashing transmission oil through gear agitation; the invention of Chinese patent application number CN200910044887.3 discloses a transmission lubricating device, the lubricating device It is a transmission oil guide plate, which is arranged in the transmission and connected with the transmission front case and the transmission rear case. The oil guide plate includes an oil guide groove and an oil delivery groove, and the oil delivery groove is drawn from the oil guide groove to each For the channel of the parts to be lubricated, an oil outlet hole is provided at the end of the oil delivery groove. The transmission lubricating oil is agitated by the hig...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the current dual-clutch hybrid transmission through the conventional gear agitation transmission oil splash lubrication method, there is a transmission oil that cannot reach the motor gears, transition gears and related needle bearings that need to be lubricated for lubrication, and the lubrication effect is poor. Insufficient to provide a transmission oil that can reach the motor gears that need to be lubricated, transition gears and related needle bearings for lubrication, and a dual-clutch hybrid transmission lubrication structure with better lubrication effect
