Output shaft one end connected row carrier of automatic transmission case, the other end is installed on gear box casing by support device, and output shaft is provided with the shaft shoulder and output gear from inside to outside successively.Support device comprises bearing, bearing comprises the roller bearing for mainly bearing radial force and the thrust bearing for mainly bearing axial force, roller bearing is installed on the shaft shoulder, be provided with pad between the outer ring of roller bearing and gear box casing, thrust bearing is in the end of output shaft and be provided with adjustment pad between thrust bearing and gear box casing.
At present, because gearbox is when overhauling, need need to change suitable adjustment pad according to size, because adjustment pad is positioned at inner side, for the ease of assembling and dismounting, the outer ring of roller bearing and gear box casing are Spielpassung.But, in running, easily cause gear box casing outer ring to wear and tear, after permanent use, the damage of other component of gearbox can be caused.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of automatic transmission case output shaft support device, the technical problem causing gear box casing outer ring to be worn and torn with the outer ring and gear box casing Spielpassung that solve existing roller bearing.
For solving the problems of the technologies described above, the technical solution of the utility model is: automatic transmission case output shaft support device, comprise the thrust bearing and radial bearing that set gradually from inside to outside, the blowout patche of described thrust bearing is set in the end of described output shaft, the seat ring of described thrust bearing is arranged on the housing of described gearbox, is provided with adjustment pad between the seat ring of described thrust bearing and the housing of described gearbox; The inner ring of described radial bearing is sleeved on the shaft shoulder of described output shaft, the outside of the inner ring of described radial bearing and the output gear of described output shaft lean, the inner side of the inner ring of described radial bearing and the blowout patche of described thrust bearing lean, the inner side of the outer ring of described radial bearing is provided with rib, pad is provided with between the housing of described rib and described gearbox, the outer ring of described radial bearing and the housing of described gearbox are fixedly installed togather, and the outside of the outer ring of described radial bearing is provided with uncovered.
Improve as one, described uncovered outside is provided with the guide portion be obliquely installed.
Improve as one, described radial bearing is roller bearing.
After have employed technique scheme, the beneficial effects of the utility model are: because automatic transmission case output shaft support device comprises the thrust bearing and radial bearing set gradually from inside to outside, the outer ring of described radial bearing and the housing of described gearbox are fixedly installed togather, thus when assembling, the outer ring of radial bearing and the housing of gearbox are assembled into one, in follow-up using process, effectively can avoid the wearing and tearing of the housing of gearbox and the outer ring of radial bearing; Meanwhile, the outside due to the outer ring of described radial bearing is provided with uncovered, and gearbox, when overhauling dismounting, makes the roller of radial bearing, inner ring and thrust bearing pull down, thus is convenient to change adjustment pad.The automatic transmission case output shaft support device that the utility model provides is by being designed to separate type by radial bearing, and not only structure is simple, and solves the wear problem of gear box casing, meanwhile, solves again the assembly problem of radial bearing.
Because described uncovered outside is provided with the guide portion be obliquely installed, by the leading role of guide portion, the retainer of radial bearing and roller are entered in the outer ring of radial bearing smoothly.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 and Fig. 2 jointly shown in, a kind of automatic transmission case output shaft support device, comprise the thrust bearing 1 and radial bearing 2 that set gradually from inside to outside, preferably, radial bearing 2 is roller bearing, the blowout patche 11 of thrust bearing 1 is set in the end of output shaft 3, and the seat ring 12 of thrust bearing 1 is arranged on the housing 4 of gearbox, is provided with and adjusts pad 5 between the seat ring 12 of thrust bearing 1 and the housing 4 of gearbox.
The inner ring 21 of radial bearing 2 is sleeved on the shaft shoulder 31 of output shaft 3, the outside of the inner ring 21 of radial bearing 2 and the output gear 32 of output shaft 3 lean, the inner side of the inner ring 21 of radial bearing 2 and the blowout patche 11 of thrust bearing 1 lean, the inner side of the outer ring 22 of radial bearing 2 is provided with rib 221, pad 6 is provided with between the housing 4 of rib 221 and gearbox, the roller 23 of radial bearing 2 is arranged in retainer 24, the outer ring 22 of radial bearing 2 is fixedly installed togather with the housing 4 of gearbox, preferably, interference fit is adopted between the outer ring 22 of radial bearing 2 and the housing 4 of gearbox, certainly, also the modes such as fastening piece can be adopted to be fixed together with the housing 4 of gearbox the outer ring 22 of radial bearing 2, be well known to those skilled in the art, do not repeat them here, the outside of the outer ring 22 of radial bearing 2 is provided with uncovered 25.
