Description
Technical Field
The utility model belongs to car axle field, concretely relates to novel transaxle wheel hub nut locking structure.
Background
In the internal automobile drive axle, the locking nut of locking plate structure is adopted to the wheel end more, and the locking plate that adopts at present is cyclic annular more to the equipartition has a plurality of round holes on its periphery, a plurality of round holes align with a plurality of screwed holes on the nut to through a plurality of bolt fastening, cooperate each other with a plurality of recesses of spindle nose tip through a plurality of dogteeth on the locking plate and be connected, and then promote the reliability. However, the locking nut has the defects of high manufacturing cost of the locking plate, heavy weight of the shaft head, complex process and the like.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned technical problem, provide a novel transaxle wheel hub nut locking structure, effectively reduce spindle nose weight and processing cost.
The utility model discloses an adopt following technical scheme to realize:
the utility model provides a transaxle wheel hub nut locking structure, nut locking structure include lock nut and locking plate, the locking plate be circular-arcly, set up respectively at the both ends of circular arc and set up a round hole two round holes between be provided with a dogtooth along radially extending in, the lock nut terminal surface on two screw holes, two round holes and two screw holes correspond each other, two round holes that the locking plate was passed respectively to two bolts to screw in two screw holes on the lock nut terminal surface, lock nut's internal thread and the external screw thread cooperation of the last spindle nose of rear axle assembly be connected, the tip of spindle nose has a plurality of groove structure along the circumferencial direction equipartition, the dogtooth of locking plate with a cooperation in a plurality of recesses is connected.
Further, the shaft head is rotatably supported by a tapered roller bearing.
Furthermore, the locking plate is formed by stamping a steel plate.
Compared with the prior art, the beneficial effects of the utility model are that: transaxle wheel hub nut locking structure, for the common cyclic annular locking plate that has a plurality of dogtooths, reduced the manufacturing cost of locking plate, reduced the weight of spindle nose.
