Labor crackle.Crackle once generate may Quick Extended, to cause the great serious accident such as brittle fractures of rail.Carry out rail ultrasound
Wave inspection is the important measures for guaranteeing the unimpeded operation of railway.
The drive axle that inspection car uses at present, semiaxis should usually transmit torque, bear moment of flexure again, due to small rail car
Entirety it is heavier, the ability to bear of semiaxis is weaker, is easy to happen fracture.
Utility model content
The technical problem to be solved by the utility model is to the drive axle of current rail detector car, semiaxis both transmitted
Torque bears moment of flexure again, is easily broken off.
The utility model is to solve above-mentioned technical problem by the following technical programs.
A kind of dedicated Quick Release drive axle of rail detector car, including axle housing and retarder, the bore at the both ends of the axle housing
Constriction, the retarder are bolted on the middle part of axle housing, and the two sides of the retarder set gradually semiaxis, braking respectively
Disk, wheel hub and bearing, one end of the semiaxis and one end of retarder connect, and the other end is fixed with wheel hub, and brake disc is fixed on
On wheel hub, bearing is mounted on wheel hub, and is mounted on one end of axle housing, and wheel hub is connected by the end rotation that axle housing is arranged in bearing
It connects.
Further, the bearing is double-row bearing.
It further, further include traveling wheel, the traveling wheel is fixedly connected with wheel hub.
It further, further include Quick-disassembling mechanism, the Quick-disassembling mechanism is fixed on axle housing.
Further, the both ends of the axle housing are respectively equipped with protrusion, and the protrusion is the small sleeve of axis and half overlapping of axles,
The small sleeve and axle housing are integrally formed.
Further, the semiaxis is connect by screw with wheel hub, and the brake disc is connected with wheel hub by boss bolt,
The wheel hub is connected with bearing by wheel hub fixture nut.
It further, further include motor, the motor is connect with the retarder.
The Quick Release drive axle is mounted on rail detector car drive axle installation place by a kind of rail detector car.
Utility model has the advantages that wheel hub is rotatablely connected by the end that axle housing is arranged in bearing, so that
Semiaxis need to only transmit torque now, without bearing moment of flexure, bear moment of flexure using axle housing now, the bearing strength of axle housing than
High more, the stable structure of holding vehicle while so as to install heavy weight body construction on drive axle of semiaxis.
