Description of drawings
Fig. 1 is the drive mechanism scheme drawing of the utility model.
The specific embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1; The utility model mainly is made up of casing, input clutch parts, drive clutch parts and output block; Described input clutch parts and drive clutch parts are respectively to be made up of the clutch components that same structure is set on input shaft and the transmission shaft, described clutch components by hold abrasive disc 7 with the oil cylinder of transmission gear 3 or 13, butterfly return spring combination 5, piston 4, thin type, driving gear 6 is formed; Described input shaft 1 is respectively arranged with operation pressure oil passage 9, clutch lubrication oil path 10 with the centre of transmission shaft 14; Output block is made up of with output shaft 12 and two supports bearing the driven gear 11 of mutual fit; The engagement of the transmission gear of the transmission gear of input clutch parts and drive clutch parts, the driving gear of the driving gear of input clutch parts and drive clutch parts are meshed with the driven gear of output block respectively.
Input shaft 1 shown in the figure is supported on the casing by self-aligning roller bearing 2 and cylindrical roller bearing 8 array modes respectively with transmission shaft 14, and the transmission gear 3 of input clutch parts and the transmission gear 13 of drive clutch parts adopt tapering interference connection mode to be placed on input shaft 1 and the transmission shaft 14 respectively.
Driving gear 6 difference radial support on described input clutch parts and the drive clutch parts are on input shaft 1 and transmission shaft 14; And they and input shaft separately 1 can relatively rotate with transmission shaft 14; The two ends of said driving gear are provided with the thin type that bears the gear axial force and hold abrasive disc 7, and in the middle of the axle of said input shaft 1 and transmission shaft 14, introduce clutch lubrication oil 10 and operation pressure oil 9.
The utility model is for adapting under high-speed state; Power-transfer clutch thoroughly take off row; Adopt belleville spring combination 5, as the return spring of the piston of power-transfer clutch, to strengthen the return force of clutch plunger; Overcome the centnifugal force of clutch plunger chamber fluid under the high-speed state, obtain the effect that clutch-lining thoroughly separates.
Described two transmission gears 3,13 of the utility model adopt the tapering interference to be connected with input shaft 1, transmission shaft 14 respectively, to make things convenient for the replacing of clutch-lining.In order to alleviate the weight of clutch components; Described two driving gears 6 radial support respectively (can relatively rotate with axle) on input shaft 1 or transmission shaft 14; Two ends are adopted thin type to hold abrasive disc 7 and are born the gear axial force, in the middle of axle, introduce clutch lubrication oil 10 and operation pressure oil 9 simultaneously.
For overcoming transmission shaft flexural deformation to the gear mesh Effect on Performance, clutch components adopts the mode of a self-aligning roller bearing 2 and cylindrical roller bearing 8 combinations to be supported on the casing.
