Description
Technical field
The utility model belongs to technical field of vehicle, relates to a kind of wheel hub oil seal structure of vehicle.
Background technology
In prior art, wheel hub is arranged on spindle nose, is provided with bearing between the inwall at described wheel hub rear portion and spindle nose, the aft end face of described wheel hub is provided with an end cap be enclosed within spindle nose; The installing space of described end cap, bearing, a sealing arrangement of encircling a city between spindle nose and wheel hub, is provided with the seal ring of annular in described installing space.But because the size of the spindle nose of full size vehicle is comparatively large, seal ring size is comparatively large, poor sealing performance.And the sealing property of existing wheel hub aft end face is also bad, easily enters dust, affects wheel and rotates normally.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of good seal performance, the simple wheel hub oil seal structure of structure.
Wheel hub oil seal structure of the present utility model, comprises the wheel hub be arranged on spindle nose, is provided with bearing between the inwall at described wheel hub rear portion and spindle nose, the aft end face of described wheel hub is provided with an end cap be enclosed within spindle nose; The installing space of described end cap, bearing, a sealing arrangement of encircling a city between spindle nose and wheel hub;
Described sealing arrangement comprises oil seal seat and seal strip, and described oil seal seat is enclosed within spindle nose, and the inwall of oil seal seat contacts with sealing between spindle nose; The front end face of described oil seal seat is provided with installation step toward the front, the inwall of wheel hub is provided with corresponding, to the rear relative to the installation step position on oil seal seat, towards rearward installation step; Two corresponding installation steps are provided with an annular seal strip, the outward flange of described seal strip and inward flange are stuck on the installation step of wheel hub and the installation step of oil seal seat; Be provided with an annular dust board between described end cap and oil seal seat, the outward flange of described dust board is close on the inwall of wheel hub, and carries out spacing to the outward flange of seal strip.Such hermetically-sealed construction is relative to traditional seal ring, and sealing reliability is high, good sealing effect.Wherein dust board not only has and carries out spacing effect to seal strip, also has the effect stoping external dust to enter installing space.
Further, in order to strengthen sealing effectiveness and sealing reliability.The front end face of described oil seal seat is provided with two-stage installation step toward the front, the inwall being positioned at the wheel hub of installing space is provided with corresponding, to the rear relative to the installation step position on oil seal seat, towards rearward two-stage installation step; Two pairs of installation steps are separately installed with an annular seal strip.
Described seal strip is made by nylon material.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the partial enlarged drawing of Fig. 1.
