Abstract
The invention relates to a wheel edge device of a semi-floating rear drive axle assembly. The wheel edge device comprises a half shaft (1), wherein a brake drum (11) is connected to the outer side of the half shaft in a matched mode, and a brake (10) is connected to the brake drum in a matched mode. The wheel edge device is characterized in that the half shaft is sleeved with a transition receiving disk (2) in a matched mode, and a bearing (5) connected with the half shaft (1) in a matched mode is arranged in the transition receiving disk; the transition receiving disk is further matched with the brake in a braking mode, a bearing baffle (8) is arranged on one side of the transition receiving disk, and a bearing locating sleeve (12) is arranged on the other side of the transition receiving disk; the bearing baffle and the bearing locating sleeve are both matched with the bearing in a limited mode and are both connected to the half shaft in a sleeving mode. The wheel edge device has the advantages that a bearing seat, an axle housing oil seal and a half shaft oil seal of an existing wheel edge device are omitted, the number of parts of the wheel edge device is reduced, the raw material cost is lowered, and the structure is compacter, so that the total weight of the rear drive axle assembly is lowered by 4%; the assembly process is simplified, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of rear driving axle assembly of automobile, particularly a kind of wheel limit device of semi-floating rear driving axle assembly.
Background technology
Along with the fierceness day by day of market competition, more and more higher to the requirement of cost of product, therefore new requirement is constantly proposed to the innovative design of automobile axle, current rear axle structure adopts decades, the optimal design of inner body has arrived ultimate attainment, structure design innovation is very urgent, and the wheel limit structure design removing bearing seat thus arises at the historic moment.
As shown in Figure 3, the existing wheel limit device with bearing seat, bearing seat 14 is provided with in brake wheel, described bearing seat 14 one end connects by transition the transition that valve snail bolt 6 is fastened on axle housing and connects on dish 2, dust boot 13 is also connected with at the other end of bearing seat 14, be connected on semiaxis 1 by bearing 5 in bearing seat 14, be respectively equipped with axle housing oil sealing 7 and axle-shaft oil seal 15 in the both sides of bearing 5.There is following shortcoming in said structure: a, bearing seat need independent forging, and it is complex-shaped, and forging quality requires high, is potential quality risk point; B, for ensure with axle housing accurate fit, independent axes bearing and axle housing all will ensure higher working accuracy, and therefore its difficulty of processing is large, cost is high; The number of parts of c, half axle assembly is more, causes wheel limit structure more complicated.In order to solve above-mentioned technical matters, through extensively retrieving, not yet find ideal technical scheme.
Summary of the invention
The wheel limit device that the object of the invention is to solve present stage semi-floating rear driving axle assembly exists, need to add independently bearing seat and cause its structure more complicated, assembling and processing request precision high, work difficulty is large, cost is high, and there is the shortcomings such as potential quality risk point, and the wheel limit device of a kind of semi-floating rear driving axle assembly proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of wheel limit device of semi-floating rear driving axle assembly, comprise semiaxis, be connected in the outside of semiaxis brake wheel, brake wheel is connected a drg, it is characterized in that: on described semiaxis, be socketed cooperation transition connect dish, connect in dish in transition and be provided with a bearing be connected with semiaxis, transition connects dish and also coordinates with brake, the side connecing dish in transition is provided with bearing baffle, opposite side is provided with bearing abutment sleeve, described bearing baffle and bearing abutment sleeve are all spacing with bearing to be coordinated, described bearing baffle and bearing abutment sleeve are all socketed on semiaxis.
On the basis of technique scheme, following further technical scheme can be had:
Between described bearing baffle and bearing, be provided with the axle-shaft oil seal that is connected, and axle-shaft oil seal is equipped with and connects in dish in described transition.
This device eliminates original bearing seat of taking turns limit device, the transition loaded by bearing on axle housing connects in dish, the axle-shaft oil seal that is connected is provided with between bearing baffle and bearing, the oil tight skeleton thickness of axle-shaft oil seal is increased to 4mm by original 2mm, not only make it can bear axial load but also have stable leak tightness, and this axle-shaft oil seal and design bearing are identical outside dimension jointly to be loaded transition and connects in dish, ensure axle-shaft oil seal and the higher right alignment quality of half between centers, this axle-shaft oil seal replaces original axle housing oil sealing and axle-shaft oil seal; Make gear ring direct contact lubricated oil in rear-axle casing simultaneously, no longer need into surface treatment, the manufacturing procedure of saving and cost; Bearing baffle and bearing abutment sleeve carry out axial limiting to bearing, ensure that bearing and oil sealing running reliably.
The invention has the advantages that: this device eliminates existing bearing seat, axle housing oil sealing and axle-shaft oil seal of taking turns limit device, decreases the number of parts of wheel limit device, reduces the cost of raw material, more compact structure, makes back axle assembly weight decline 4%; Simplify the assembly process of wheel limit device, improve the production efficiency of back axle; The oil tight skeleton thickness of the axle-shaft oil seal of this device is increased to 4mm by 2mm, radial direction and end face fine-grinding, can ensure that bear axially loaded ensures assembling and positioning precision simultaneously, decreases the quality risk point of wheel limit structure, reduce the use cost of client, improve Vehicle Economy.
