Abstract
A rear axle comprises an axle casing, a bearing, a half axle gear, a differential casing, a driven wheel, a planetary gear, a planetary gear axis, a half axle and a brake, and is characterized in that one end of the half axle of the rear axle, which is connected to the differential, is supported at an interior wall of the axle casing by the bearing, while the differential is not supported but floating.
Description
Affiliated technical field
The utility model relates to a kind of back axle with diff, and it is that a kind of diff floats, and the back axle that the semiaxis that is attached thereto does not float.
Background technology
At present, known band diff back axle is made up of axle housing, bearing, axle side gear, differential gear box, flower wheel, planetary wheel, compensating-gear shaft, semiaxis, drg.Semiaxis and diff connecting portion adopt floating structure, and on axle housing, the differential shell is bigger by bearings for differential gear box, so the volume of axle housing is also bigger, make the back bridge construction too fat to move and huge.
Summary of the invention
Have the bulky of axle housing now in order to overcome, the deficiency that back bridge construction is too fat to move, the utility model provides a kind of back axle, its semiaxis and diff bonded assembly one end by bearings on axle housing, and differential gear box adopts floating structure, and this back axle is simple in structure, the volume-diminished of axle housing.
The technical scheme that its technical matters that solves the utility model adopts is: on axle housing, and differential gear box adopts floating structure by bearings for the semiaxis of back axle and diff bonded assembly one end, and the volume-diminished of axle housing makes back axle simple in structure.
The splined section of rear axle shaft is connected with axle side gear, and in the two-semiaxle gear outside, semiaxis supports with two bearings respectively, and the outer ring of bearing is fixed on the inwall of axle housing, and the shell of diff just need not be supported on the axle housing like this, but floats.Because the axle housing that semiaxis than little with the diff shell, adopts semiaxis to support is also little than the axle housing that diff supports, the volume-diminished of axle housing makes back axle simple in structure.
The beneficial effects of the utility model are that the volume of axle housing is little, and the support of diff and semiaxis is placed on the semiaxis, and is simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is part sectional view of the present utility model.
1. axle housings among the figure, 2. bearing, 3. axle side gear, 4. differential gear box, 5. flower wheel, 6. planetary wheel, 7. compensating-gear shaft, 8. semiaxis.
The specific embodiment
In the drawings, planetary wheel (6) connects together by compensating-gear shaft (7) and differential gear box (4), the splined section of semiaxis (8) is connected with axle side gear (3), in two-semiaxle gear (3) outside, semiaxis (8) uses two bearings (2) to support respectively, the outer ring of bearing (2) is fixed on the inwall of axle housing (1), and differential gear box (4) just need not be supported on the axle housing (1) like this.
Claims (1)
1. a back axle is made up of axle housing, bearing, axle side gear, differential gear box, flower wheel, planetary wheel, compensating-gear shaft, semiaxis, drg, it is characterized in that: rear axle shaft and diff bonded assembly one end use bearings on the inwall of axle housing, diff need not support, but float.
