The utility model discloses such an improved middle and rear axle housing structure. In order to solve the problems existing in the existing middle and rear axle housings such as easy cracking along the 45° direction and relatively difficult processing, the utility model adopts the front pipa hole (3) and the rear pipa hole (5) are processed into an oval shape, and the end surface of the front pipa hole (3) is 85-89mm from the center of the axle housing, and the end surface of the front pipa hole (3) is provided with a reducer mounting screw. There are 18-22 holes, and two reducer positioning pin holes are symmetrically processed on the center line of the rear cover (4). Therefore, it has the advantages of high safety and low production cost.
Description
Affiliated technical field the utility model relates to rear-axle casing structure in the used improved type of automobile.
Background technology is present, rear-axle casing in the fertile Steyr of a kind of like this 09 section of person of outstanding talent is disclosed on the market, its constructional feature is: rear-axle casing housing in comprising, bonnet and telescoping termination flanged shaft, the two ends of rear-axle casing housing during described telescoping termination flanged shaft is connected to, the middle part of rear-axle casing housing is provided with the Chinese lute hole that retarder can be installed in described, described Chinese lute hole is made up of preceding Chinese lute hole and Chinese lute hole, back, the rear, back Chinese lute hole at rear-axle casing housing middle part during bonnet is arranged on, preceding Chinese lute hole end surface is provided with the fork hole, its preceding Chinese lute hole and Chinese lute hole, back are circular port, corresponding what use is the Steyr retarder to rear-axle casing in 09 section of fertile Steyr of person of outstanding talent, in use, large end face in 09 section of fertile Steyr of person of outstanding talent on the rear-axle casing is prone to along the cracking of 45 ° of directions, in addition, in the course of processing, because the right alignment in fork hole and preceding Chinese lute hole and Chinese lute hole, back requires height, its difficulty of processing is bigger.
The summary of the invention the purpose of this utility model provides rear-axle casing structure in the improved type that a kind of large end face is not easy to crack, difficulty of processing is lower.
For achieving the above object, rear-axle casing structure in the utility model improved type, rear-axle casing housing in comprising, bonnet and telescoping termination flanged shaft, the two ends of rear-axle casing housing during described telescoping termination flanged shaft is connected to, the middle part of rear-axle casing housing is provided with the Chinese lute hole that retarder can be installed in described, described Chinese lute hole is made up of preceding Chinese lute hole and Chinese lute hole, back, the rear, back Chinese lute hole at rear-axle casing housing middle part during bonnet is arranged on, Chinese lute hole and Chinese lute hole, back are processed into and are ellipticity before described, preceding Chinese lute hole end surface is 85-89mm apart from the axle housing center height, the Chinese lute hole end surface is provided with retarder and installs screw 18-22 before described, is processed with two retarder dowel holes on described bonnet line of centers symmetrically.
The Chinese lute hole end surface is 87mm apart from the axle housing center height before described.
Before described Chinese lute hole and Chinese lute hole, back for by one square two trapezoidal constitute be elliptoid hole.
The Chinese lute hole end surface is provided with retarder 20 of screws is installed before described.
After adopting this structure, since with the preceding Chinese lute hole on the rear-axle casing in 09 section of fertile Steyr of person of outstanding talent and Chinese lute hole, back be processed into by one square two trapezoidal constitute be elliptoid hole, make that rear-axle casing is complementary with the benz retarder in 09 section of fertile Steyr of person of outstanding talent, thereby eliminated the potential safety hazard that is prone to cracking phenomena on the large end face, again because, saved the fork hole, further improved production efficiency, simultaneously also reduce disqualification rate, saved productive costs.
The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.
Fig. 1 is the main cross-sectional schematic of rear-axle casing structure in the utility model improved type.
Fig. 2 is the schematic top plan view of Fig. 1.
Among the figure: 1. Chinese lute holes, 4. bonnets, 5. back, Chinese lute holes before the telescoping termination flanged shaft 2. rear-axle casing housings 3..
Specific embodiment Fig. 1, rear-axle casing structure in the utility model improved type shown in Figure 2, rear-axle casing housing 2 in comprising, bonnet 4 and telescoping termination flanged shaft 1, the two ends of rear-axle casing housing 2 during described telescoping termination flanged shaft 1 is connected to, the middle part of rear-axle casing housing 2 is provided with the Chinese lute hole that retarder can be installed in described, described Chinese lute hole is made up of preceding Chinese lute hole 3 and Chinese lute hole, back 5,5 rears, back Chinese lute hole at rear-axle casing housing 2 middle parts during bonnet 4 is arranged on, Chinese lute hole 3 and Chinese lute hole, back 5 are processed into and are ellipticity before described, preceding Chinese lute hole 3 tip to face distance axle housing center heights are 85-89mm, Chinese lute hole 3 end faces are provided with retarder and install screw 18-22 before described, are processed with two retarder dowel holes symmetrically on described bonnet 4 line of centerss; Chinese lute hole 3 tip to face distance axle housing center heights are 87mm before described; Before described Chinese lute hole 3 and Chinese lute hole, back 5 for by one square two trapezoidal constitute be elliptoid hole; Chinese lute hole 3 end faces are provided with retarder 20 of screws are installed before described.
