Abstract

The invention discloses a mechanical automatic gearbox, comprising: a gearbox and a cooling device, the gearbox includes a gearbox casing and a gearbox assembly arranged in the gearbox casing, the cooling device is arranged in the outside the transmission housing and communicate with the inner cavity of the transmission housing for cooling the transmission assembly. The mechanical automatic transmission provided by the present invention aims to solve the problem in the prior art that under heavy load conditions, the performance of the transmission is often degraded due to the inability to withstand a large heat dissipation pressure, which endangers driving safety.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a mechanical automatic transmission and an automobile. Background technique [0002] The gearbox is one of the three major parts of the car, and it is a very important part of the car. It plays the role of changing the transmission ratio and expanding the torque and speed of the driving wheels. 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. There are many forms of automatic gearboxes, mainly including hydraulic automatic gearboxes (AT), Dual-clutch automatic transmission (DCT), continuously variable automatic transmission (CVT) and mechanical automatic transmission (AMT). Among them, AT, DCT and CVT have problems such as high cost and difficult maintenance, and are not suitable for commercial vehicles. Therefore, Usually com...
