Description

Built in controllable over run sliding clutch

Technical field

The utility model belongs to the vehicular clutch technical field, is specifically related to a kind of built in controllable over run sliding clutch.

Technical background

Motorcycle slider popular on the existing market mostly is external, and it is built-in that minority is also arranged.The external glider separates with motor, clutch, is installed in the trailing wheel place more, exists volume big, and is stressed big, dustproof poor, lubricate shortcomings such as bad; And built-in be that glider is installed in the motor because structural design unreasonable can only be realized unidirectional sliding, can not controlled " counter dragging ", implement auxiliary braking, have hidden danger, configuration needs SC.

Summary of the invention

The purpose of this utility model is the deficiency at the prior art existence, a kind of built in controllable over run sliding clutch is provided, Wet-type multi-disc friction clutch and free wheeling device are combined as a whole, be built in the motor, the function that possesses friction clutch and controllable over run sliding simultaneously, compact structure, simple, volume is little, lubricate, entrucking is easy.

In order to achieve the above object, the utility model is by the following technical solutions:

Built in controllable over run sliding clutch is to be constituted by Wet-type multi-disc friction clutch and free wheeling device.The clutch component of Wet-type multi-disc friction clutch is made up of conventional part, comprises friction disk, friction plate, platen, pressing spring, bolt and lift slab, and the conventional configuration of bearing and push rod is controlled by rotational arm of clutch.The change part of clutch is: change the central sleeve internal spline of clutch component into unthreaded hole, be placed on the lining that is fixed on the transmission main shaft.It is in the driven gear assembly of one that clutch component places by stack of rivets a string of flowers keyboard, gear ring, cushion collar and outer cover.The driven gear assembly is by flower keyboard and starting gear key cover.Simultaneously a free wheeling device is set between flower keyboard and clutch component, the raceway rings of free wheeling device is inlayed or is riveted on the platen of clutch component, and the multi-surface disk key of free wheeling device is placed on the transmission main shaft.

Described free wheeling device is two-way controllable slide structure, is made of multi-surface disk, retainer, roller, block plate, steel ball and raceway rings.Raceway rings is socketed on the multi-surface disk, and roller places in the arcuate region that raceway rings and multi-surface disk surround, and the retainer with inside and outside step ladder circular ring shape and a plurality of stepped slots slides on the setting circle of multi-surface disk, the spacing and control to roller.Multi-surface disk is covered with block plate outward near flower keyboard one end, is provided with resetting-mechanism between block plate and the retainer, makes retainer and flower keyboard be in separated state under routine.

The working principle of this device is: when engine output power passes to the driven gear assembly, this moment, the central sleeve of clutch component was in the separation operating mode with platen if the clutch rim brake is closed, and the driven gear assembly only dallies, can not give clutch component with transmission of power, motorcycle is in the Parking state.If the clutch rim brake loosens, central sleeve is in platen and combines operating mode, and platen is owing to combine with raceway rings, raceway rings is rotated thereupon, and this moment, the free wheeling device assembly was in " combination " position, and power is passed to main shaft by free wheeling device, this moment, on gear, motorcycle moved ahead as if motor.When in the motorcycle driving during oil return door, motor is in idling operation, driven gear assembly rotating speed reduces, because action of inertia, transmission main shaft drives multi-surface disk and keeps the rotation situation, surmounting pulley arrangement is in and surmounts coasting mode, motorcycle utilizes coast, so oiling-combination-acceleration, oil return-surmount-slide, go round and begin again, to reach the purpose of fuel-economizing.

In motorcycle driving, slow down or chance descending highway section as need, elder generation's oil return door, make motorcycle be in sliding state, hold clutch rim brake handle again, central sleeve is separated with platen, the raceway rings of inlaying on the platen or riveting overcomes the elastic force of resetting-mechanism, and its end face makes retainer contact with flower keyboard against the omoplate face of retainer, make retainer overcome the torsion of torsion spring and circumferential displacement by the frictional force between them, force the roller displacement, multi-surface disk combines with raceway rings is reverse, delays this moment to put clutch rim brake handle, central sleeve, platen and friction disk, the slow combination of friction plate, reply gear, driven gear assembly and crank driving tooth slowly recover transitive relation, impact thereby eliminate, realize not having counter the dragging of impact, slow down reposefully.

Obviously, model utility has two-way controllable overrunning simultaneously and slides and two kinds of functions of friction clutch, compact structure, and volume is little, and is easy and simple to handle, driving safety, with engine configurations, high lubricating effect can reduce maintenance, and entrucking is easy.
