Gear speed change mechanism with efficient lubricating effect

Abstract

The invention provides a gear speed change mechanism with the efficient lubricating effect, and relates to the field of cars. The gear speed change mechanism with the efficient lubricating effect comprises a gearbox body, two first bearings are fixedly connected to the inner wall of the gearbox body, the inner rings of the two first bearings are fixedly sleeved with input shafts, the input shaftsare hollow, the ends, away from the right side of the inner wall of the gearbox body, of the input shafts penetrate through the gearbox body and extend to the outer portion of the gearbox body, a driving gear is fixedly inserted to the position, located on the outer surfaces of the input shafts, in the gearbox body, and a first transmission gear is engaged to the tooth grain position of the driving gear. According to the gear speed change mechanism with the efficient lubricating effect, through a lubricating oil pump, lubricating oil in the gearbox body can be conveyed into the input shafts and a rotating shaft through lubricating oil pipes and branch pipes, through lubricating holes and lubricating grooves, lubricating oil flows to positions between gears, and the gears can be lubricated.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a gear transmission mechanism with high-efficiency lubricating effect. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; It is composed of torque converter, planetary gear, hydraulic pitch change system and hydraulic control system. Variable speed and torque are achieved through hydraulic transmission and gear combination. [0003] At present, the automotive gearboxes on the market, especially the dry gearboxes, are prone to wear during long-term operation, and due to the poor lubrication effect of the transmission gears during long-term load operation, the transmission gears will generate high temperatures, which will speed up the wear and tear of the trans...
