Abstract

Disclosed is a motor economizer indirect differential retaining mechanism. The utility model is characterized in that a star wheel 2 and a pusher dog disc 3 are sleeved on a shaft sleeve 1 and then arranged in the hole of an external ring 4; the pusher dog disc 3 is made to cling to the star wheel through the shaft shoulder of the shaft sleeve 1; clearance is left between the pusher dog disc 3 and an adjacent friction disc 6; the friction disc 6 is connected into a step hole of the external ring 4; an escape-prevention drive pin 5 is fixed on the external ring 4; the inner plane of the friction disc 6 is connected with the external ring 4 by a spring 7 and the outer plane is contacted with a point pressure bearing 13 of a controller 12. The thickness of the utility model is reduced, the space for installation is saved, the sealability is improved while the abrasion becomes smaller and the braking becomes more reliable.

Description

Energy-saving apparatus for motorcycle indirection type differential braking mechanism

One, technical field:

The utility model relates to a kind of arrestment mechanism, especially energy-saving apparatus for motorcycle indirection type differential braking mechanism.

Two, background technique:

Disclosed Chinese patent ZL01247886.5 " energy-saving apparatus for motorcycle differential motion ", because outer shroud is different with star wheel rotate speed when sliding, directly act on claw plate by steering controller, utilize differential principle to produce frictional force and make the claw plate counter-rotating, make on the claw plate pusher dog initiatively roller dial in raceway sipes place on the star-wheel, promoted by spring and will brake that roller pushes the narrow slit place and the star-wheel wedging is an one, realization is braked.Though it has overcome the shortcoming of general arrestment mechanism, because the claw plate of this device can axial float, in braking process, the claw plate operating conditions is undesirable, quick abrasion, the braking reliability is relatively poor, simultaneously, this device must seal with dust-proof cover, because of steering controller directly contacts claw plate,, so just make the economizer thickening so steering controller must be installed in the dust-proof cover, be unfavorable for the installation of economizer, and sealing is relatively poor.

Three, summary of the invention:

The purpose of this utility model provides a kind of energy-saving apparatus for motorcycle indirection type differential braking mechanism, by changing the structure of former economizer differential attachment, solves the installation inconvenience that the economizer differential attachment exists, the thickness broad, and wearing and tearing are big, problems such as braking poor reliability.

Concrete scheme of the present utility model is: comprise that axle sleeve, star-wheel, claw plate, outer shroud, spring, braking roller, active roller, spring distribution, pusher dog, steering controller, some last item hold, it is characterized in that: star-wheel, claw plate are sleeved on the axle sleeve, place in the outer annular distance; Claw plate is abutted in by the shaft shoulder of axle sleeve by the star-wheel, and is gapped between claw plate and the adjacent friction disk; Friction disk is connected in the outer shroud step hole by the anticreep driving pin, and the anticreep driving pin is fixed on the outer shroud; The inner plane of friction disk is connected with outer shroud through spring, and the some last item of outerplanar and steering controller is accepted and touched.

Adopt such scheme, not only dwindled thickness, saved installing space, sealing improves, and it is less to wear and tear, and brakes more reliable.

Four, description of drawings:

Fig. 1 is a plan view of the present utility model;

Fig. 2 is the left view of Fig. 1.

Five, embodiment:

Please see Figure 1, Fig. 2, the utility model mainly by axle sleeve 1, star-wheel 2, claw plate 3, outer shroud 4, anticreep driving pin 5, friction disk 6, spring 7, braking roller 8, initiatively roller 9, spring promote 10, pusher dog 11, steering controller 12, some last item hold 13 etc. and form.Structure characteristic of the present utility model is: star-wheel 2, claw plate 3 are sleeved on the axle sleeve 1, place in outer shroud 4 holes; It is other that claw plate 3 abuts in star-wheel 2 by the shaft shoulder of axle sleeve 1, gapped between claw plate 3 and the adjacent friction disk 6; Friction disk 6 is connected in outer shroud 4 step holes by anticreep driving pin 5, and anticreep driving pin 5 is fixed on the outer shroud 4; The inner plane of friction disk 6 is connected with outer shroud 4 through spring 7, and outerplanar holds 13 with the some last item of steering controller 12 and contacts.

Please see Figure 2, in the raceway groove that pusher dog 11 on the claw plate 3 inserts between outer shroud 4 and the star-wheel 2, and with active roller 9 with the braking roller 8 contact, initiatively roller 9 and braking roller 8 are headed on by spring distribution 10 again, spring is promoted 10 and is installed on the star-wheel 2, raceway groove on the star-wheel 2 is two head breadths, middle narrow wedge groove.

Working principle of the present utility model is: motorcycle is in driving process, because the effect of anticreep driving pin 5, outer shroud 4 and friction disk 6 are all unitary rotation; Because claw plate 3 inserts in the star-wheel 2 wedge grooves, star-wheel 2 also is all unitary rotation with claw plate 3 again.Surmount when sliding when motorcycle is in, the rotating speed of star-wheel 2 and claw plate 3 is much larger than the rotating speed of outer shroud 4 with friction disk 6.When motorcycle need not slide, can press friction disk 6 right sides by 13 on the bearing of steering controller 12, friction disk 6 is pressure spring 7 immediately, contact with the right side of claw plate 3, because of differential principle moment generation frictional force, claw plate 3 is reversed immediately, pusher dog 11 on the claw plate 3 is dialled in wedge groove width place with the active roller 9 on the star-wheel 2, and braking roller 8 is promoted 10 effect at spring, be pushed to wedge groove narrow slit place, is one with outer shroud 4 with star-wheel 2 wedgings, makes the anti-motor that drags of trailing wheel of quick rotation, and this moment, motor played braking action.
