Transmission and vehicle

Abstract

The invention provides a transmission and a vehicle. The transmission comprises a shell, a bearing, a mounting opening and a retainer. A counter bore is formed in the shell, and a locating groove is formed in the hole wall of the counter bore. The bearing is arranged in the counter bore, a locking groove is formed in the peripheral side face of the outer ring of the bearing, and the locking grooveis opposite to the locating groove. The mounting opening is arranged on the sell and communicates with the locating groove. The retainer is arranged in the locking groove and the locating groove. Inthe mounting process, the retainer is arranged in the locating groove, and the retainer can be adjusted through the mounting opening so as to mount the retainer in the locking groove. The locating groove used for locating the retainer is arranged in the counter bore, a conventional bearing locating structure arranged on the outer side of the counter bore is omitted, and therefore the thickness ofthe shell in the bearing axis direction is greatly reduced, and the grinding length of the counter bore and the shell processing cost are reduced so as to achieve the technical effects of optimizing the bearing locating structure of the transmission, reducing the space requirement of the transmission and reducing the production cost of the transmission.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular, to a transmission and a vehicle. Background technique [0002] In general vehicles, such as figure 1 As shown, when designing the positioning structure of the bearing 6' of the automobile transmission, the stopper 8' arranged on the end face of the bearing 6' is generally used to locate the outer ring of the bearing 6'. In this structure, the transmission housing 2' is provided with an inner cavity 4', and the depth of the inner cavity 4' is greater than the thickness of the bearing 6', a positioning groove is also provided on the hole wall of the inner cavity 4', and the blocking piece 8' is installed on the positioning groove, and one end surface of the blocking piece 8' is connected with the The end faces of the outer ring of the bearing 6' abut against each other, so as to realize the axial positioning of the bearing 6' through the inner cavity 4'. However, this stru...

AI Technical Summary

Problems solved by technology

However, this structure requires that the housing 2' has enough thickness to be provided with the inner cavity 4' for installing the bearing 6' and the snap ring. The technical problem of interference, and this positioning method increases the axial length of the transmission, so that the vehicle must provide a larger space for installing the transmission, which destroys the overall layout of the vehicle interior
