Abstract
The invention discloses a novel hub bearing unit for a driving wheel. The novel hub bearing unit for the driving wheel comprises a flange plate, an inner ring and a driving half axle, wherein an internal spline is arranged in the flange plate; the driving half axle is arranged in the flange plate; an external spline is arranged on the driving half axle; the inner ring is arranged on the external side of the right end of the flange plate; the internal spline and the external spline have same lengths and widths; and the longitudinal section of the internal spline is gradually enlarged from the left end to the right end. According to the invention, the novel hub bearing unit for the driving wheel is advantaged in that the distance between the internal spline and the external spline at one end is reduced through adjusting single side inclination angle according to the length of the internal spline so that the internal spline and the external spline can preferably fit each other and cannot generate abnormal impact sound due to large clearance; as buffering grooves are formed in the longitudinal section of the internal spline, one group of buffering grooves is formed in each side of the internal spline and each group includes at least two buffering grooves, the compression strength of the internal spline is enhanced; and as a wear-resisting layer is arranged outside the internal spline, the wear of the internal spline in the operation process is reduced and the service life of the internal spline is prolonged.
Description
Technical field
The invention belongs to automobile mechanical field, be specifically related to a kind of novel drive wheel hub-bearing unit.
Background technology
Within drive wheel hub-bearing unit and jack shaft, male splines is connected, power is passed to tire assembly, car is moved, existing drive wheel hub-bearing unit flange female splines is in spline fitted region, space width is consistent, easily gap is there is in the flange female splines that existing space width is consistent after coordinating with jack shaft male splines, major cause is female splines and male splines all needs certain production tolerance adding man-hour, gap can be there is when the limit coordinates, exist gap can make automobile advance and fall back gear switch time produce abnormal sound, abnormal sound source is male splines shock female splines, cause being unsatisfied with of vehicle operator, easily cause the problem that cannot assemble compared with the male splines of steep-taper according to band.
Summary of the invention
For solving the problem, the invention discloses a kind of novel drive wheel hub-bearing unit, with by the problem solving inside and outside spline gaps and cause greatly abnormal sound or cannot assemble.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of novel drive wheel hub-bearing unit, comprise flange, inner ring, jack shaft, in described flange, female splines is set, described jack shaft is arranged in flange, jack shaft arranges male splines, described inner ring is arranged at outside flange right-hand member, and described female splines is all identical with width with male splines length, and female splines vertical section is increased to right-hand member gradually by left end.
As a modification of the present invention, described female splines single sided taper angle is 1 ' 46 "-3 ' 20 ".
As a modification of the present invention, the spacing between described female splines and male splines is reduced to right-hand member gradually by left end.
As a modification of the present invention, outside described female splines, wearing layer is set.
As a modification of the present invention, described female splines vertical section arranges dashpot, one group, every limit, one group at least two.
A novel drive wheel hub-bearing unit processing technology, it is characterized in that, described technique comprises:
(1) broaching tool is utilized to process female splines in flange;
(2) inner ring is pressed in flange, and the magnitude of interference controlling inner ring and flange is 0.039 ~ 0.067mm.
The invention has the beneficial effects as follows:
A kind of novel drive wheel hub-bearing unit of the present invention, the angle of inclination monolateral according to the length adjustment of female splines, distance between the female splines of one end and male splines is reduced, thus can coordinate preferably, the abnormal sound clashed into can not be produced because gap is comparatively large, vertical section arranges dashpot to female splines, one group, every limit, one group at least two, improve the pressure resistance of female splines, wearing layer is set outside female splines, reduces the wearing and tearing of female splines in operation, extend the service life of female splines.
