Abstract
The utility model discloses a hub reduction axle housing used for Dongfeng automobiles, which aims at solving the problems that the existing hub reduction axle housing of Dongfeng automobiles has high cost of the axle housing assembly; and stress is easily concentrated at the welded part of the axle housing, thus leading the welded part thereof to be broken. In the hub reduction axle housing, an axle housing tube (1) is in hot matching with the shell (3) of a rear axle housing, and then riveted with the rear axle housing; an end flange (2) is provided with 12 to 18 flange holes; a straight mouth for mounting a reducer is round; the diameter of an inner straight mouth is 305 to 311 millimeters; the diameter of an outer straight mouth (4) is 307 too 313 millimeters; and the center height of the reduction axle housing is 80 to 82 millimeters. The hub reduction axle housing used for Dongfeng automobiles has the advantages of low cost of axle housing assembly, high safety and the like.
Description
Affiliated technical field the utility model relates to the hub reduction axle housing that is used for Dongfeng Automobile.
Background technology is present, what the hub reduction axle housing correspondence of Dongfeng Automobile was used is benz bridge speed reducer assembly, this type of speed reducer assembly manufacturing cost is higher, technical requirements to axle housing is also higher, thereby increased the manufacturing cost of axle housing, therefore, make the hub reduction axle housing of this Dongfeng Automobile exist total cost higher, the not ideal enough deficiency that waits of durability, form by deceleration axle housing housing and axle tube owing to this hub reduction axle housing again, two axle tubes are connected to the two ends of deceleration axle housing housing, and its connection mode is welding, therefore, there is the phenomenon that easily stress concentration takes place in using and rupture, influences vehicle driving safety.
The summary of the invention the purpose of this utility model provides a kind ofly can reduce the axle case assy manufacturing cost, improve durability, simultaneously, can guarantee a kind of vehicle rear-axle housing of vehicle driving safety again.
For achieving the above object, the utility model is used for the hub reduction axle housing of Dongfeng Automobile, comprise rear-axle casing housing and axle tube, described axle tube is connected to the two ends of deceleration axle housing housing, also be provided with and drg bonded assembly termination flange at the two ends of described deceleration axle housing housing, at the middle part of described deceleration axle housing housing is the straight mouth that retarder is installed, described straight mouth is made up of interior Zhi Kou and outer straight mouth, a straight mouthful periphery is equipped with the Chinese lute hole outside described, after joining, described axle tube and rear-axle casing housing heat is riveted together, on the flange of described termination, be provided with 12-18 flange hole, straight mouthful that is installed in retarder for circular, straight mouthful diameter is 305-311mm in described, and described outer straight mouthful diameter is 307-313mm, and described deceleration axle housing center height is 80-82mm.
Described termination flange is provided with 12 flange holes.
Straight mouthful diameter is 308mm in described, and described outer straight mouthful diameter is 310mm, and described deceleration axle housing center height is 81mm.
Chinese lute hole number on described outer straight mouthful is 12.
After adopting this structure, owing to be riveted together after axle tube and rear-axle casing housing heat joined, eliminate the stress concentration that causes because of welding and easily produced the phenomenon of fracture, again because the oval outer straight mouth that retarder is installed at deceleration axle housing housing middle part changes circular straight mouthful that is suitable for installing the Steyr speed reducer assembly into, simultaneously, saved the auxiliary hole in straight mouthful, reduced the cost of axle case assy, show through actual measurement, under the situation of output same torque, its wear life is also longer, thereby has greatly improved the service life and the work efficiency of product.
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 a kind of vehicle rear-axle housing of the utility model.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Among the figure: 1. axle tube 2. termination flanges 3. rear-axle casing housings 4. are straight outward mouthful.
Specific embodiment the utility model shown in Figure 1 is used for the hub reduction axle housing of Dongfeng Automobile, comprise rear-axle casing housing 3 and axle tube 1, described axle tube 1 is connected to the two ends of deceleration axle housing housing 3, also be provided with and drg bonded assembly termination flange 2 at the two ends of described deceleration axle housing housing 3, at the middle part of described deceleration axle housing housing 3 is the straight mouth that retarder is installed, described straight mouth is made up of interior Zhi Kou and outer straight mouth 4, straight mouthful 4 peripheries are equipped with the Chinese lute hole outside described, described axle tube 1 is riveted together after joining with rear-axle casing housing 3 heat, on described termination flange 2, be provided with 12-18 flange hole, straight mouthful that retarder is installed is circular, straight mouthful diameter is 305-311mm in described, described outer straight mouthful 4 diameter is 307-313mm, and described deceleration axle housing center height is 80-82mm; Described termination shown in Figure 2 flange 2 is provided with 12 flange holes; Described interior straight mouthful diameter shown in Figure 1 is 308mm, and the diameter of described outer straight mouth 4 is 310mm, and described deceleration axle housing center height is 81mm; Chinese lute hole number on described outer straight mouthful 4 is 12.
