Description

The wheel hub motor braking device

Technical field

The utility model relates to the wheel hub motor braking device that Wheel-chair or tricycle for the disabled or old man's car are especially taken turns in a kind of electric motor car.

Background technique

Motor wheel hub brake in the market, the handle complicated operation will draw afterwards earlier and change, twice action just can be finished the operation of release brake, and the long strip projection of handle inboard matches with the groove on the shell, and surface friction drag is big during operation, it is also unreliable to locate, and has serious potential safety hazard.

Summary of the invention

It is a kind of when using manual release brake function that the purpose of this utility model is to provide, rapid operation, and simple and convenient, the location is reliable, wheel hub motor braking device safe in utilization.

In order to achieve the above object, the technical solution of the utility model is: a kind of wheel hub motor braking device, comprise handle, shell, armature, friction plate, coil, iron core, spring, coil is installed in the cavity that forms between shell and the iron core, armature is between iron core and friction plate, spring is housed in the shell, spring housing is contained on the spring pull bar, one end of spring pull bar can be resisted against on the armature, and shell also is provided with clutch plate outward, and clutch plate is fixedlyed connected with handle, between handle and clutch plate, banking stop is housed, banking stop is fixedlyed connected with the other end of spring pull bar, and projection or pit are arranged on the clutch plate, and corresponding pit or projection are arranged on the shell.

Adopt after the said structure, because shell also is provided with clutch plate outward, clutch plate is fixedlyed connected with handle, between handle and clutch plate banking stop is housed, and banking stop is fixedlyed connected with the other end of spring pull bar, projection or pit are arranged on the clutch plate, corresponding pit or projection are arranged on the shell, therefore rotate a left side (right side) handle, the projection on the clutch plate is separated with pit on the shell, the wheel Wheel-chair is in when removing the brake function state, and the wheel Wheel-chair can not have electric hand control operation; When handle resets, can realize brake function.Thereby rapid operation, simple and convenient, the location is reliable, and is safe in utilization.

Embodiment

The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.

As Fig. 1,2,3,4,6, shown in 7, a kind of wheel hub motor braking device, comprise handle 13, shell 1, armature 2, friction plate 3, coil 4, iron core 5, spring 6, coil 4 is installed in the cavity that forms between shell 1 and the iron core 5, armature 2 is between iron core 5 and friction plate 3, spring 6 is housed in the shell 1, spring 6 is sleeved on the spring pull bar 6-1, spring pull bar 6-1 front end can be resisted against on the armature 2, the shell 1 outer clutch plate 10 that also is provided with, clutch plate 10 is fixedlyed connected with handle 13, between handle 13 and clutch plate 10, banking stop 7 is housed, banking stop 7 is fixedlyed connected with the other end of spring pull bar 6-1, and protruding 10-1 or pit are arranged on the clutch plate 10, and corresponding pit 1-2 or projection are arranged on the shell 1.

Shown in Fig. 1,3,4, be evenly equipped with the spring eye 1-1 more than three or three on the shell 1, spring 6 and spring pull bar 6-1 thereof all are housed among each spring eye 1-1; Make like this between spring pull bar 6-1 and the banking stop 7 stressed evenly, effectively guaranteed its using effect and working life.The spring eye 1-1 that the utility model is taked is 4.

As shown in Figure 6, in order not allow handle 13 unconfined rotations, clutch plate 10 is quincunx, and when clutch plate 10 rotated by a certain direction, the projection 10-2 of clutch plate 10 can offset with locking nut 6-2 or the spring pull bar 6-1 shaft of spring pull bar 6-1.

Handle 13 in the utility model can comprise handle 13-1 and rotating disk 13-2.Also can include only rotating disk 13-2.

The utility model in use, as shown in Figure 1, when the utility model uses, during coil 4 energisings, electromagnetic force adhesive armature 2, armature 2 moves to left, and the backstop on the pressuring spring pull bar 6-1 makes spring 6 compressions, friction plate 3 separates with the wheel hub motor axle, and motor runs well, the electric motor car operation; When coil 4 outages, under the elastic force effect of spring 6, promote spring pull bar 6-1 right lateral, the backstop compressing armature 2 on the spring pull bar 6-1 makes armature 2 right laterals compressing friction plate 3, and friction plate 3 is coupling to touch with wheel hub motor and offsets, and checks wheel hub motor.Use when manually breaking away from brake function, rotate handle 13 several angles, the protruding 10-1 on the clutch plate 10 cooperates with pit 1-2 disengaging on the shell 1, handle 13 moves to left, and drives spring pull bar 6-1 and moves to left, and friction plate 3 disengages with the wheel hub motor axle, car is in relieved state, can the hand push operation.As go back to handle 13 several angles, protruding 10-1 on the clutch plate 10 snaps among the pit 1-2 on the shell 1, handle 13 moves to right under spring 6 elastic force fast, driving spring pull bar 6-1 moves to right fast, the backstop compressing armature 2 that moves to right, armature 2 is oppressed friction plate 3 again, and friction plate 3 moves to right to be coupling with wheel hub motor and touches, offsets, thereby check wheel hub motor, car is in braking state.
