Abstract
The utility model discloses a rear axle applicable for cars and mini cars, wherein, a wheel hub is supported to the journal of an axle shaft by a bearing unit combined with two rows of back-to-back single-row taper rollers; the baring combination unit is positioned on a step arranged on the journal corresponding to the middle of the wheel hub and matching with the bearing combination unit; the outmost end of the journal is provided with a lock nut. The utility model has the advantages of simple assembly, reasonable bearing stress, reduction of eccentric abrasion to the tires and more reliable oil seal, solves the deficiencies in the prior art that the service life of the bearing is short and the axial assembly of the wheel hub is large, reduces the non-suspension mass of the vehicle, and improves the smoothness and economy.
Description
Technical field
The claimed affiliated technical field of technical scheme of the utility model is a kind of back axle that is suitable for car or minicar use.
Background technology
The back axle total structure of general automobile is made up of driving axle housing, retarder, diff, semiaxis and wheel hub, and wheel hub is bearing on the axle tube by bearing, and the wheel hub outer end covers with the metal cap of punching press, and oil sealing is equipped with in the wheel hub inboard.Concrete mounting means is: earlier a tapered roller bearing is inserted on the axle journal of semiaxis outer end the end with support cage, subsequently wheel nave is packed into, the last other end that is inserted in a tapered roller bearing support cage on the axle journal of semiaxis outer end is adjusted the elasticity and the position of bearing by the adjustment nut of bearing outer end.The defective of this structure is: the installation of bearing is to eccentric and clean environment degree sensitivity, but the bearing endplay of this kind structure and installation site adjustment bother very much, are difficult to reach requirement, and oil sealing damages easily in addition; Therefore the point corrosion of bearing is serious, and often shorten dramatically service life, and this structure makes wheel hub and other fitted position axial distance of back axle thereof big, causes the non-suspended mass of automobile heavy, and ride comfort and economy are affected.
Technical scheme
Technical problem to be solved in the utility model is exactly that block bearing assembling is simple, long service life, structure more reasonably are applicable to the back axle that car and minicar are used.
The scheme of the utility model technical solution problem is such: by driving axle housing, retarder, diff, the automobile axle that semiaxis and wheel hub are formed, wheel hub is bearing on the axle journal of semiaxis by the single-row tapered roller bearing assembled unit of two row dos-s pairing, the position of bearing assembled unit is positioned at making up on the step that matches with bearing of offering on the corresponding axle journal of wheel hub middle part institute, on the outermost end of axle journal fastening screw nut is housed, when therefore installing, only need the bearing combination directly is sleeved on the corresponding axle journal step, also tightly get final product with nut again, need not adjust endplay, and the installation site is accurate.So-called dos-combination is meant that the bearing load line deviates from bearing axis and scatter, and this bearing combination has higher rigidity, can bear capsizing moment, also can bear the bi-directional axial load.
The bearing combination of said structure also can be designed as a double-row conical bearing and is replaced.And interior outer oil seal can be directly installed between the Internal and external cycle of bearing with further raising oil sealed effect and life-span and reduce the axial installation dimension of wheel hub.
The utility model has following good effect compared with the prior art: wheel hub and the supporting semiaxis between the assembling simple and easy, can once assemble success; Bearing makes up in back-to-back mode, and is stressed reasonable; The oil sealing effect is more reliable; So can reduce the tire eccentric wear, prolong bearing service life, and this structure makes wheel hub and other fitted position axial distance of back axle thereof greatly reduce, the non-suspended mass of automobile reduces, and ride comfort and economy all are improved.
Description of drawings
Fig. 1 is the structural representation of bearing combination.
Fig. 2 is the structural representation of an optimal way of the utility model.
The specific embodiment
Bearing combination shown in Figure 1 is the embodiment that realizes technical solutions of the utility model easily, the bearing assembled unit 1 of two single-row tapered roller bearing 2 dos-s pairings, spacer ring 3 is arranged between outer ring of the two and the inner ring, this bearing combination 1 can be directly installed on the corresponding axle journal step, again with nut and tight.
Fig. 2 is an optimal way of the present utility model, wheel hub 10 is installed on the axle journal 8 of semiaxis 9 by the supporting of double-row conical bearing 4, mill out a step 6 on the axle journal 8, the position of step 6 is positioned at the middle part of wheel hub 10, its position and dimensional accuracy are all identical with the requirement of double-row conical bearing 4, the load line of two row tapered rollers in the double-row conical bearing 4 deviates from bearing axis and scatter, and between double-row conical bearing 4 Internal and external cycles oil sealing 7 is housed.The outer end jam nut 5 of bearing 4 is in order to fixing double-row conical bearing 4.
Claims (3)
1, the back axle of car and minicar, form by driving axle housing, retarder, diff, semiaxis (9) and wheel hub (10), it is characterized in that: wheel hub (10) is bearing on the axle journal (8) of semiaxis (9) by the single-row tapered roller bearing assembled unit (1) of two row dos-s pairing, the position of bearing assembled unit (1) be positioned at wheel hub (10) middle part on the step (6) that matches with bearing assembled unit (1) offered on the corresponding axle journal (8), jam nut (5) is housed on the outermost end of axle journal (8).
2, the back axle of car according to claim 1 and minicar is characterized in that: bearing combination (1) also can be a double-row conical bearing (4).
3, the back axle of car according to claim 2 and minicar is characterized in that: oil sealing (7) is directly installed between the Internal and external cycle of bearing (4).
