Gearbox oil circuit system and gearbox

Abstract

The present disclosure relates to the technical field of automatic transmissions, and in particular to a gearbox oil circuit system and a gearbox. The gearbox oil circuit system includes a first oil circuit on the input shaft, a second oil circuit on the transmission shaft, an output The third oil passage, support plate and support seat opened on the shaft, the support plate is fixedly installed on the inner wall of the gearbox housing, and the support plate is provided with a The sixth oil passage of the road, the support seat includes a first support seat and a second support seat, the first support seat is arranged on the support plate, and supports the transmission shaft, and the first support seat is provided with A fourth oil passage communicating with the sixth oil passage and the second oil passage. The system can set up the sixth oil passage and the first support seat on the support plate, so that the support plate can not only support the internal parts of the gearbox, but also act as one of the oil passages in the entire oil passage system. road.

Description

technical field [0001] The present disclosure relates to the technical field of automatic transmissions, in particular to a transmission oil circuit system and a transmission. Background technique [0002] Automobile gearbox is a set of transmission devices used to coordinate the engine speed and the actual driving speed of the wheels, and is used to exert the best performance of the engine. The gearbox can generate different gear ratios between the engine and the wheels during the running of the car to realize the transmission of different gear speeds. [0003] There are two types of gearboxes: 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; while the automatic gearbox AT is composed of a hydraulic torque converter, a planetary gear and a hydraulic control system. , through the way of hydraulic transmission and gear combination to achieve the purpose of var...

Problems solved by technology

[0005] As one of the most important systems of automatic transmission, the oil circuit system is not only related to the cooling and lubrication efficiency of the entire transmission, but also spreads throughout every corner of the entire transmission. However, the current automatic transmission is not only severely limited in volume At the same time, the internal structure is also becoming more complex following the needs of customers, which makes it difficult to obtain sufficient layout space for the intricate oil system. In addition, most of the currently used oil system is the oil pipe structure inside the shell, which leads to oil The hydraulic system is difficult to design, and there will be more conflicts between the oil circuit system and other structures inside the gearbox, which not only brings more difficult assembly work for the gearbox, but also makes the later maintenance of the gearbox more difficult.
