Description
Technical field
The utility model relates to a kind of retarder, is specifically related to a kind of vehicle bridge wheel reductor.
Background technique
Wheel reductor is mainly used on heavy-duty car, mine dumping car or large-bus, and the advantage of wheel reductor is to have larger final ratio, and the retarder of reduced size can ensure enough ground Clearances.Planetary gear reduction formula wheel reductor conventional in prior art is primarily of structure member compositions such as wheel hub, end cap and planet wheels, in order to prevent oil leak of reducer, usually at hub inner lumen assembling oil sealing, but this sealing means is difficult to stop the dust being entered wheel hub by brake disc inner chamber, not only increase the frequency of more oil change, and the working life of retarder can be reduced.
Summary of the invention
The utility model provides a kind of vehicle bridge wheel reductor, improves the sealing effect of retarder, prevents dust from entering, and increases the working life of retarder.
Technological scheme adopted to achieve these goals: a kind of vehicle bridge wheel reductor, comprise planetary wheel carrier, supporting axle, sun gear, several rows star-wheel and wheel hub, sun gear is sleeved on supporting axle, planetary wheel carrier has planet wheel shaft, planet wheel is sleeved on planet wheel shaft by needle bearing, and sun gear is meshed with planet wheel; Gear ring is connected with gear ring supporting base, and the sleeve pipe that gear ring supporting base is fixed on supporting axle can not rotate, and planet wheel is meshed with gear ring; Planetary wheel carrier is connected with wheel hub; The end face of wheel hub is connected with seal ring, and the internal diameter of described seal ring is enclosed within supporting axle, and the interior edge face of seal ring fits tightly the end face of wheel hub.
Power is passed to sun gear by supporting axle, because gear ring is motionless, therefore power is passed to wheel hub by one group of planet wheel, planetary wheel carrier by sun gear, thus driving vehicle wheel rotation, due to the seal ring that wheel hub end face is installed, even if therefore vehicle travels in dust granules rugged environment, also can effectively blocks dust be entered in wheel hub by brake disc inner chamber.
Preferably, described seal ring is U-shaped seal ring.Seal ring can adopt O type circle, Y-shaped ring.The U-shaped seal ring of preferred employing, because it has good corrosion-resistant and wear-resisting property, symmetrical dual lip configuration can form good lubricant film in seal clearance, has no effect to shock load.
Further, the part that supporting axle is connected in wheel hub has step surface, and the step surface of supporting axle connects a seal ring, and described seal ring comprises endless metal skeleton and rubber sleeve, the cross section of endless metal skeleton is L-type, and rubber sleeve is installed on endless metal skeleton; Metal frame is supported on the step surface place of supporting axle, the inner chamber interference fit of rubber sleeve and wheel hub.
Above-mentioned seal ring structure can effectively prevent dust from entering hub inner lumen, cooperatively interacts, improve sealing effect further with seal ring.
The center of wheel hub has through hole, and supporting axle is connected with wheel hub by bearing, and the side of bearing is set with oil baffle, back-up ring and oil sealing successively.
The oil sealing of oil baffle end assembling can seal effectively to inner chamber lubricant oil, exocoel dust.
The various sealing configurations of the utility model by installing additional at different parts, can effectively prevent dust from entering, and increase the working life of retarder.
