Abstract
The utility model relates to a rear hub dismounting device of a car passenger. The rear hub dismounting device comprises a gasket, a nut and a screw rod, wherein one end of the screw rod is provided with a rotating bar; the rotating bar is fixed to the screw rod through the nut and the gasket; the outer wall at the other end of the screw rod is provided with a cone-shaped block; and a tensioning block which is in taper fit with the cone-shaped block is sleeved on the radial outer side of the cone-shaped block. The rear hub dismounting device is simple in structure, convenient in use and high in dismounting efficiency.
Description
Technical field
The utility model relates to a kind of passenger vehicle rear-wheel hub attaching/detaching apparatus.
Background technology
Passenger vehicle is very common as a kind of vehicles commonly used.In order to ensure the traffic safety of passenger vehicle, every operation a period of time of passenger vehicle, just need to maintain passenger vehicle.Wherein, requisite working procedures to the bearing lubrication on the trailing wheel and braking maintenance and inspection thereof, because outer bearing and bearings mounted sleeve pipe in the rear-wheel hub are interference fit, the now artificial dismounting of general employing, efficient is low, and easily to the wheel rim injury.
Summary of the invention
A kind of passenger vehicle rear-wheel hub of the utility model attaching/detaching apparatus, purpose is in order to overcome problems of the prior art.
For realizing above purpose, the technical scheme that the utility model is taked is: a kind of passenger vehicle rear-wheel hub attaching/detaching apparatus, comprise pad, nut, screw mandrel, one end of described screw mandrel is provided with swingle, swingle is fixed by nut and pad and screw mandrel, on the other end outer wall of described screw mandrel circular cone is installed, the circular cone radial outside is set with the expanding block with the circular cone taper fit.
Described expanding block shape is trapezoidal.
Described circular cone both sides are equipped with pad and nut along the screw mandrel direction.
The utility model is simple in structure, easy to use, dismounting efficient high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, pad 1, nut 2, screw mandrel 3, swingle 4, circular cone 5, expanding block 6.
The specific embodiment
The utility model is described in further detail below in conjunction with Fig. 1.
A kind of passenger vehicle rear-wheel hub attaching/detaching apparatus, comprise pad 1, nut 2, screw mandrel 3, one end of described screw mandrel 3 is provided with swingle 4, swingle 4 is fixing with screw mandrel 3 by nut 2 and pad 1, on the other end outer wall of described screw mandrel 3 circular cone 5 is installed, circular cone 5 radial outsides are set with the expanding block 6 with circular cone 5 taper fit.
Described expanding block 6 shapes are trapezoidal.
Described circular cone 5 both sides are equipped with pad 1 and nut 2 along screw mandrel 3 directions.
During use, a side that screw mandrel 3 is equipped with circular cone 5 is inserted in the sleeve of passenger vehicle rear-wheel hub, rotate again swingle 4, because swingle 4 is fixed on the screw mandrel 3 by pad 1 and nut 2, this moment, screw mandrel 3 meetings were along with rotating together, under the effect of turning moment, circular cone 5 is expanded to screw mandrel 3 outsides, because expanding block 6 has the tapering that matches with circular cone 5, circular cone 5 can be propped up expanding block 6, thereby sleeve is strutted, and can pull down rear-wheel hub or install from bearing quickly and easily this moment, very convenient, and can injury to the wheel rim of rear-wheel hub.The utility model is simple in structure, easy to use, dismounting efficient high.
