Abstract
The utility model relates to a novel miniature axle wheel limit structure of adoption two -row ball bearing, by semi -axis 1, end ring 2, bearing frame 3, the rear wheel brake assembly 4, bearing frame connecting bolt and nut 5, two -row ball bearing 6, position sleeve 7, axle housing 8 is constituteed, two -row ball bearing 6 assembles in the axle journal department of semi -axis 1, the inner circle of two -row ball bearing 6 is fixed by end ring 2 and position sleeve 7, the outer lane of two -row ball bearing 6 is by bearing frame 3 and 8 location of axle housing, bearing frame 3, axle housing 8 and rear wheel brake assembly 4 is connected by bearing frame connecting bolt and nut 5, wherein, bearing frame 3 and axle housing 8 all has the oil blanket. This structure adopts the two -row ball bearing to fix a position it through bearing frame etc. Because equal specification two -row ball bearing bearing capacity is far above single -row ball bearing, consequently taking turns limit bearing capacity can promote by a wide margin, and arranges and basically do not increase semi -axis radial space size, has realized compact design.
Description
Technical field
This utility model belongs to automobile drive axle technical field of structures, is specifically related to a kind of novel Miniature axle wheel rim structure using two-row ball bearing.
Background technology
At present, domestic micro axle rim all uses semifloating axle shaft supporting structure, and semifloating axle shaft not only transmits moment of torsion but also bear moment of flexure, and its supporting typically uses single-row ball-bearing structure.Show according to substantial amounts of market feedback information, micro axle rim single-row ball-bearing inordinate wear, inefficacy incidence rate generally the highest, and affected by space layouts, single-row ball-bearing cannot improve bearing capacity by the further of specification.
Utility model content
For the problems referred to above, this utility model is by using two-row ball bearing, on the premise of not increasing wheel edge semiaxis radial space size, is simultaneously achieved the lifting of compact design and wheel limit bearing capacity, and each part life in wheel limit is greatly improved.
The technical solution of the utility model is achieved in that
A kind of novel Miniature axle wheel rim structure using two-row ball bearing, it is made up of semiaxis 1, end ring 2, bearing block 3, rear wheel brake assembly 4, bearing block connecting bolt and nut 5, two-row ball bearing 6, positioning sleeve 7, axle housing 8, two-row ball bearing 6 is assemblied at the axle journal of semiaxis 1, the inner ring of two-row ball bearing 6 is fixed by end ring 2 and positioning sleeve 7, the outer ring of two-row ball bearing 6 is positioned by bearing block 3 and axle housing 8, and bearing block 3, axle housing 8 and rear wheel brake assembly 4 are attached by bearing block connecting bolt and nut 5.
Further, bearing block 3 and axle housing 8 all have oil sealing.
This utility model uses the Miniature axle wheel rim structure of two-row ball bearing, and is positioned it by bearing block etc., two-row ball bearing supporting semiaxis and axle housing, realize semiaxis rotate axle housing fixing while, carry from semiaxis and axle housing axially and radial load.Owing to equivalent specifications two-row ball bearing bearing capacity is far above single-row ball-bearing, therefore wheel limit bearing capacity significantly improves, and does not the most increase semiaxis radial space size in layout, it is achieved that compact design.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of novel Miniature axle wheel rim structure using two-row ball bearing of the present utility model.
In figure: semiaxis 1, end ring 2, bearing block 3, rear wheel brake assembly 4, bearing block connecting bolt and nut 5, two-row ball bearing 6, positioning sleeve 7, axle housing 8.
Detailed description of the invention
A kind of novel Miniature axle wheel rim structure using two-row ball bearing, it is made up of semiaxis 1, end ring 2, bearing block 3, rear wheel brake assembly 4, bearing block connecting bolt and nut 5, two-row ball bearing 6, positioning sleeve 7, axle housing 8, two-row ball bearing 6 is assemblied at the axle journal of semiaxis 1, the inner ring of two-row ball bearing 6 is fixed by end ring 2 and positioning sleeve 7, the outer ring of two-row ball bearing 6 is positioned by bearing block 3 and axle housing 8, bearing block 3, axle housing 8 and rear wheel brake assembly 4 are attached by bearing block connecting bolt and nut 5, and bearing block 3 and axle housing 8 all have oil sealing.
During enforcement, first two-row ball bearing 6 is pressed into bearing block 3, forms bearing block sub-unit；Again rear wheel brake assembly 4 is installed on bearing block sub-unit by bearing block connecting bolt and nut 5, forms bearing block and rear wheel brake sub-unit.Then end ring 2 is pressed against on semiaxis 1 diameter of axle shoulder, be then pressed into bearing block and brake sub-unit, finally press-in positioning sleeve 7, form semiaxis sub-unit.Finally semiaxis sub-unit loaded axle housing 8 sub-unit and connected with bearing block connecting bolt and nut 5.At present, using the Miniature axle wheel rim structure of two-row ball bearing to pass through each level verification and embodied in car load real vehicle, in the field of business have the innovation advantage used first.
