Abstract
The invention discloses a stepless speed change clutch. The stepless speed change clutch comprises a driving wheel assembly, a transmission belt and a driven wheel assembly, wherein the driving wheel assembly comprises a driving shaft, a drive disc, a shaft sleeve, a spring seat, a spring and a moving wheel, and also comprises a synchronous ring and a disc spring which are arranged between the shaft sleeve and the spring seat; the synchronous ring presses and leans against an outer ring of a rolling bearing; the disc spring presses and leans against the synchronous ring and the spring seat. The stepless speed change clutch disclosed by the invention has the advantages that since the transmission belt has certain rotating speed under an idle-speed state, the problems of slip and wearing of the transmission belt are avoided in the process of starting acceleration; in the changing process of a vehicle from the idle-speed state to the starting acceleration, the driving wheel assembly drives the driven wheel assembly to rotate by the transmission belt; since the driven wheel assembly has certain rotating speed under the idle-speed state, in the process of starting acceleration of the vehicle, the change of the rotating speed of the driven wheel assembly is stable, no problem of shaking in acceleration occurs, and further the starting stability of the vehicle is good.
Description
Technical field
The present invention relates to a kind of clutch, particularly a kind of stepless speed change clutch.
Background technique
Usually, stepless speed changes devices comprises driving wheel combination, follower combination and driving belt, and driving wheel combination is connected with engine crankshaft, and when engine crankshaft rotates, driving wheel drives follower to rotate by driving belt, outputs power.
There is the shortcoming of vehicle launch stationarity difference in stepless speed changes devices of the prior art, reason is: existing stepless speed change clutch, and when driving wheel rotating speed is in idling mode, driving belt has the initiative on the axle sleeve of axle, driving belt transfixion, and then follower is also in transfixion state; When vehicle transfers starting acceleration to by idling, driving belt just contact by transmission of power to follower with driving wheel, and follower is directly zero transfer to and accelerate starting state by initial speed, and follower velocity variations is large and unexpected, make to produce serious jitter phenomenon, cause vehicle start stationarity poor.And in starting overshoot, static belt contacts with the driving wheel of high speed rotating, and belt easily skids, occur serious wear problem.
Summary of the invention
In view of this, the object of this invention is to provide a kind of stepless speed change clutch, to solve the problem that existing motorcycle electrodeless variable-speed clutch exists starting stationarity difference.
Stepless speed change clutch of the present invention, comprise driving wheel combination, driving belt and follower combination, described driving wheel combination comprises driving shaft, drive plate, axle sleeve, spring seat, spring and movable pulley, described drive plate, spring seat is fixed on driving shaft, described axle sleeve is between drive plate and spring seat, and be fixed on driving shaft by rolling bearing, described movable pulley one end is enclosed within spring seat by sliding bearing, the other end of described movable pulley is enclosed within driving shaft by sliding bearing, one section, described spring withstands on spring seat, the other end withstands on movable pulley, the combination of described driving wheel also comprises and is arranged on synchronizing ring between axle sleeve and spring seat and disc spring, described synchronizing ring is pressed against on the outer ring of rolling bearing, described disc spring is pressed against on synchronizing ring and spring seat.
Further, the end face of described spring seat is provided with circular orientation circle, described synchronizing ring and disc spring are arranged on circular orientation circle.
Further, described drive plate is provided with radiating fin, the height of described radiating fin is 10 ~ 20mm.
Beneficial effect of the present invention:
Stepless speed change clutch of the present invention, synchronizing ring is pressed on the outer ring of rolling bearing by disc spring by it, make in the idling state, also with driving shaft synchronous axial system under the frictional force effect of axle sleeve between itself and synchronizing ring, driving belt simultaneously on axle sleeve also rotates with axle sleeve, and then driving belt drives again follower to combine rotation, therefore in idling process, follower combination is also in rotation status when accelerating starting state, driving shaft rotating speed improves, driving belt leaves axle sleeve and moves to and contact with movable pulley with drive plate, because driving belt has had certain rotating speed at idling mode, make in acceleration starting-up process, driving belt and drive plate contact with movable pulley and there will not be slippage problems, the driving belt that alleviates that can be very large weares and teares, and become acceleration starting-up process at vehicle from idling mode, driving wheel is combined through driving belt and drives follower combination to rotate, because follower is combined in idling mode, there is certain rotating speed, therefore in vehicle acceleration starting-up process, the change of follower combined rotational speed steadily, there will not be the problem accelerating shake, and then make vehicle start stationarity good.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of stepless speed change clutch of the present invention;
Fig. 2 is the zoomed-in view in A portion in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment stepless speed change clutch, comprise driving wheel combination, driving belt 1 and follower combination, described driving wheel combination comprises driving shaft 2, drive plate 3, axle sleeve 4, spring seat 5, spring 6 and movable pulley 7, described drive plate 3, spring seat 5 is fixed on driving shaft 2, described axle sleeve 4 is between drive plate 3 and spring seat 5, and be fixed on driving shaft 2 by rolling bearing 10, described movable pulley 7 one end is enclosed within spring seat 5 by sliding bearing, the other end of described movable pulley is enclosed within driving shaft 2 by sliding bearing, 6 one sections, described spring withstands on spring seat 5, the other end withstands on movable pulley 7, the combination of described driving wheel also comprises and is arranged on synchronizing ring 8 between axle sleeve 4 and spring seat 5 and disc spring 9, described synchronizing ring 8 is pressed against on the outer ring of rolling bearing 10, described disc spring 9 is pressed against on synchronizing ring 8 and spring seat 5.
Under idling shape body, the present embodiment stepless speed change clutch, because synchronizing ring 8 is pressed on the outer ring of rolling bearing 10 by disc spring 9 by it, make in the idling state, also with driving shaft 2 synchronous axial system under the frictional force effect of axle sleeve 4 between itself and synchronizing ring, driving belt 1 simultaneously on axle sleeve also rotates with axle sleeve 4, and then driving belt 1 drives again follower to combine rotation, and therefore in idling process, follower combination is also in rotation status.
When accelerating starting state, driving shaft rotating speed improves, the movable pulley vertically mobile driving belt that promotes leaves axle sleeve to contacting with movable pulley with drive plate, because driving belt has had certain rotating speed at idling mode, make in acceleration starting-up process, driving belt and drive plate contact with movable pulley and there will not be slippage problems, and the driving belt that alleviates that can be very large weares and teares; And become acceleration starting-up process at vehicle from idling mode, driving wheel is combined through driving belt and drives follower combination to rotate, because follower is combined in idling mode, there is certain rotating speed, therefore in vehicle acceleration starting-up process, the change of follower combined rotational speed steadily, there will not be the problem accelerating shake, and then make vehicle start stationarity good.
