Driving shaft intermediate support and supporting and locating structure

Abstract

The invention provides a driving shaft intermediate support and a supporting and locating structure. The driving shaft intermediate support comprises a fixing part and a supporting part, wherein the fixing part is connected to an engine cylinder body; the supporting part is used for supporting a driving shaft; the supporting part consists of two parts; the part A is integrally molded with the fixing part; a big semicircular hole is formed in the part A; a driving shaft long-handle ball cage and a bearing of the driving shaft are accommodated in the big semicircular hole; the part B is separated from the part A; a small semicircular hole is formed in the part B; the part B is closed with the part A and connected with the part A through a bolt; and therefore, the driving shaft long-handle ball cage and the bearing can be clamped in a formed matching hole. According to the driving shaft intermediate support and the supporting and locating structure, before a whole vehicle is assembled, one part of the support is first separately assembled together with the engine cylinder body; by using a certain technological method, the assembling accuracy of the support is guaranteed; after the driving shaft and a transmission are assembled, the other part of the support is assembled by using the bolt so that the support and the bearing generate interference fit with each other; and meanwhile,the positioning of the support and the bearing is guaranteed. The driving shaft intermediate support has the advantages of simple structure, reliable connection, high positioning accuracy and the like.

Description

technical field [0001] The invention belongs to automobile parts, in particular to a positioning structure between a drive shaft support, a drive shaft bearing and an engine cylinder block. Background technique [0002] At present, the right drive shaft of the car is mostly a long handle with a bracket structure, and the bracket is fixed to the engine block by bolts to support and fix the long handle of the drive shaft. The structure that generally adopts now is that support and bearing, drive shaft long handle are assembled as a whole and cooperate with speed changer, engine. see figure 1 with figure 2 , the existing structure is that the drive shaft support 1, the bearing 2, and the drive shaft long-handle ball cage 3 are assembled into a whole by press-fitting. The upper part of the matching hole of the cylinder body and the lower part are supporting parts, and the bearing 2 is press-fitted through the matching hole. This structure has few assembly parts and simple a...
