Shell of gearbox

Abstract

The invention discloses a shell of a gearbox. The shell of the gearbox comprises a main shell body, a torque converter shell and a middle separation board. The main shell body, the torque converter shell and the middle separation board are each provided with a high-pressure oil path capable of conveying oil in a clutch into the gearbox. According to the shell of the gearbox, the main shell body, the torque converter shell and the middle separation board are all provided with high-pressure oil paths; the high-pressure oil paths are utilized to serve as an oil transportation passage, so the oil inside the clutch can be directly transported into the gearbox, and an additional oil transportation pipe does not need to be arranged; accordingly, the structure and manufacturing process of the gearbox are simplified, the production efficiency of the gearbox is improved, and the possibility of breakdowns in the working process of the gearbox is reduced.

Description

technical field [0001] The present invention relates to the technical field of gearboxes, more specifically, to a casing of a gearbox. Background technique [0002] The gearbox housing part is a key part of the gearbox. It assembles the gears, shafts, bearings, clutch plates and other components in the gearbox into a whole, and keeps them in the correct position with each other, so that the components The transmission power is coordinated according to a certain transmission relationship. Specifically, the casing of the gearbox includes a main casing, a torque converter casing and an intermediate partition. [0003] During the working process of the gearbox, it needs to supply clutch oil to its internal clutch to realize its normal operation. In the prior art, the gearbox generally has two types of casings. One type of casing is that its main casing, torque converter casing and intermediate partition are not provided with oil passages. , it is necessary to add an appropria...

Problems solved by technology

[0004] For the above two kinds of housings, the gearbox without oil delivery channel, because the clutch oil is added in advance, in the subsequent work process, it is impossible to accurately control the amount of oil according to the actual working conditions, so as to ensure the normal operation of the gearbox. brought some adverse effects, and another gearbox with oil pipes in the housing can solve this problem

However, when the gearbox with the oil delivery pipe in the housing is manufactured, in addition to opening the through hole on the casing, the oil delivery pipe also needs to be laid, which not only makes the manufacturing process of the gearbox more loaded down with trivial details, but more importantly, also makes the transmission of the gearbox more complicated. The structure is more complex, which increases the chance of failure
