Description
Technical field
The utility model relates to engaging and disengaging gear, especially has the automatic clutch device of stepless shift function.
Background technique
At present, on Motor Vehicle, generally all to dispose clutch and gearbox, clutch function and speed changing function are normally separate, and clutch is connected between the bent axle and gearbox input of motor, and clutch is the operation access or the disconnection of realization power down of power externally.Gearbox generally also adopts the gearbox of fixed speed ratio, can't realize automatic stepless speed change.
The model utility content
The purpose of this utility model provides a kind of belt transmission stepless change automatic clutch device that is connected between engine crankshaft and the gearbox input shaft.
For this reason, belt transmission stepless change automatic clutch device described in the utility model comprises active clutch, by dynamic clutch and drivign belt, active clutch with linked by drivign belt by dynamic clutch.Active clutch is made of fastening flange, slip flange, spring, equilibrium block and outer cover, middle mind-set one side of fastening flange is extended with sleeve, slip flange kink is on this sleeve, form the V-arrangement circumferential groove between two opposing sides of fastening flange and slip flange, outer cover is installed in a side of slip flange, and is provided with equilibrium block and spring between outer cover and slip flange; Constituted by fastening flange, slip flange, cam hoof, cam and spring by dynamic clutch, middle mind-set one side of fastening flange is extended with sleeve, slip flange kink is on this sleeve, form the V-arrangement circumferential groove between two opposing sides of fastening flange and slip flange, cam is installed in slip flange one side, and between slip flange and cam, be provided with spring, cam hoof on the slip flange matches with the guiding groove on the cam, and drivign belt is socketed in the V-arrangement circumferential groove of active clutch and by between the V-arrangement circumferential groove of dynamic clutch.
The fastening flange of active clutch is connected on the bent axle of motor in the utility model by bolt, slip flange and outer cover are connected to one in the axial direction, linked to each other with the input shaft of gearbox by bolt by the fastening flange of dynamic clutch, cam is not removable in the axial direction yet.When the engine crankshaft rotating speed hour, the centrifugal force of equilibrium block is not enough to overcome the elastic force of spring, fastening flange and slip flange can not clamp drivign belt, drivign belt is in relaxed state and can not transferring power.After engine crankshaft reaches certain rotating speed, the centrifugal action that covers on equilibrium block outward drives down the slip flange and moves and clamp drivign belt to fastening flange, and according to the position between automatic adjustment of rotating speed and the fastening flange, promptly regulate the width of active clutch V-arrangement circumferential groove automatically, the position of drivign belt contact V-arrangement circumferential groove is changed, thereby change the working diameter of drivign belt on active clutch; Simultaneously, from dynamic clutch, the slip flange changes at the effect upper/lower positions of drivign belt lateral force, V-arrangement circumferential groove width between this slip flange and the corresponding fastening flange is changed, the position that drivign belt contacts this V-arrangement circumferential groove also changes, thereby change drivign belt in the working diameter from dynamic clutch, change velocity ratio between the driving and driven clutch, reach the purpose of stepless change and automatic clutch with this.
The beneficial effects of the utility model are: as the transmission device that is connected between engine crankshaft and the gearbox input shaft, both can realize automatic clutch, also have stepless shift function, and simple in structure, reliable operation.
