Abstract
The utility model discloses a passenger car non-driving wheel hub unit assembly which comprises a flange outer ring, an inner ring, a core shaft with flange plane, two steel balls and two retainers; the inner side of the flange outer ring is provided with two lines of inner channels; the outer side of the inner ring and the outer side of the core shaft are respectively provided with outer channels; the two steel balls are respectively arranged in the retainers and between the flange outer ring and the inner ring, and between the flange outer ring and the core shaft; double four-lip sealing assembly components are arranged between the flange outer ring and the core shaft; an oil seal assembly component is arranged between the flange outer ring and the inner ring. The passenger car non-driving wheel hub unit assembly adopts the oil seal assembly component, to effectively reduce the friction moment and working temperature increase of the unit assembly and improve the sealing performance. Adoption of the double four-lip sealing assembly components realizes multiple and multi-channel sealing, so as to fully ensure lubrication and cleaning of the unit assembly, so that the passenger car non-driving wheel hub unit assembly has higher sealing performance and reliability.
Description
[technical field]
The utility model relates to auto parts and components, relates in particular to passenger car non-driving wheel hub unit assembly.
[technical background]
At present, the pivoting support of small-sized riding wheel has mostly adopted the hub assembly structure, and this structure not only can be simplified installation procedure, dwindles installing space, has improved the intensity and the rigidity of wheel hub simultaneously; Particularly along with the development of electronic information technology, on hub, also disposed wheel speed sensors, the velocity information of wheel running reflects running state of the vehicle, makes control system can initiatively prevent automobile wheel lock up phenomenon when emergency braking, guarantees that automobilism is safer.
But there is two large problems technically in present passenger car non-driving wheel hub unit assembly:
1, because sealing configuration is unreasonable and/or the Sealing assembly technology is unreasonable, tend to cause the friction torque of unit assembly to increase and the very high phenomenon of temperature rise, especially poor sealing causes lubricated bad, the wearing and tearing increase of unit assembly, finally causes reliability decrease.
2, the reliability of sensor is not high, and jitter causes interference to control system, even does the control that makes mistake.
[summary of the invention]
The purpose of this utility model is exactly in order to solve problems of the prior art, proposes a kind of passenger car non-driving wheel hub unit assembly, can improve sealability, strengthens reliability.
For achieving the above object, the utility model patent has proposed a kind of passenger car non-driving wheel hub unit assembly, comprise the flange outer ring, inner ring, the mandrel on flanged plane, two row steel balls, two retainers, inboard, described flange outer ring is provided with raceway groove in the biserial, the inner ring outside and the mandrel outside are respectively equipped with outer raceway groove, two steel balls are installed in the retainer respectively, and be separately positioned between flange outer ring and inner ring and flange outer ring and the mandrel, be provided with dual four lip seal assemblies between described flange outer ring and the mandrel, be provided with the oil seal type black box between flange outer ring and the inner ring.
As preferably, described dual four lip seal assemblies comprise seal ring Steel Skeleton and four lip seal circles, described seal ring Steel Skeleton and flange outer ring interference fit, four sealing lips of four lip seal circles are distributed in respectively on the Flange Plane of mandrel neck, mandrel foundation circular arc middle part, mandrel foundation circular arc bottom and mandrel.According to the form structure of outer ring and mandrel, adopt four sealing lips multiple multiple-sealed, fully ensured the lubricated and cleaning of unit assembly.
As preferably, also comprise magnetic circle and sensor, described magnetic circle is equably attached on the steel ring, and the steel ring interference is fitted on the rib of inner ring, and the lower end is turned up a right angle again, and sensor is installed in the end of flange outer ring by sensor stand.The magnetic circle is fixed by steel ring, improved reliability, the right angle that turn up the steel ring lower end is as oil baffle, the direct crush seal assembly of the oiling agent of blocking unit inside II, magnetic circle integral intensity and stability had so both been increased, strengthen sealing effect again, also reduced the cost of production of magnetic circle.
As preferably, described sensor stand is the hood-shaped of sealing, covers the end of whole flange outer ring.Be assemblied on the flange outer ring, form together dustproof barrier.
As preferably, the thick 1.75mm of described magnetic circle, high 10.6mm.Adopt magnetic circle performance the best of this size.
The beneficial effect of the utility model patent: the utility model adopts the oil seal type black box, has reduced the friction torque and the work temperature rise of unit assembly effectively, has strengthened sealability.It is multiple multiple-sealed to adopt dual four lip seal assemblies to realize, has fully ensured the lubricated and cleaning of unit assembly.Make passenger car non-driving wheel hub unit assembly have higher sealability, strengthened its reliability.
