Description
Technical field: the utility model relates to a kind of power-transfer clutch.
Background technology: at present the ZJ220 cross-country car since when dispatching from the factory front axle be by the Spindle nose cover bonded assembly, its propons and back axle drive four-wheel simultaneously and rotate.No matter be on muddy, bumpy road surface, still on smooth road surface, this car is to be in the four wheel drive state all the time.Above structure makes that the oil consumption of vehicle is big, noise is big, speed is low, mechanism wear is serious.Though Toyota's 4500 automobiles are equipped with power-transfer clutch on spindle nose, there is following shortcoming in its power-transfer clutch: the one, and the amount of radially wobbling is big; The 2nd, because it is to drive the work of slip gear ring by dual spring, so its structure more complicated, manufacturing cost are higher, reliable operation is relatively poor; The 3rd,, need and will front-wheel could be taken off after the split of spindle nose power-transfer clutch during front-wheel in maintenance, install more loaded down with trivial detailsly, maintenance load is big.ZL95210545 has announced a kind of " drive axle head clutch ", and there is the shortcoming of functional reliability difference in its engaging and disengaging gear.
Summary of the invention: the utility model is a kind of automobile spindle nose power-transfer clutch of design, and it has solved existing four-wheel drive car because the problem that oil consumption is big, noise is big, speed is low, mechanism wear is serious that no spindle nose power-transfer clutch causes.Problems such as the amount of radially wobbling that it has also solved existing various automobile spindle nose power-transfer clutch existence is big, functional reliability is poor, maintenance load is big, cost is high, the life-span is low.The utility model comprises adjusting knob 1, shell 4, internal tooth casing 7, internal gland 8, spline overcoat 9, compression spring 10, sliding sleeve 12, the adjusting turn-knob 1 that is positioned at shell 4 left ends is captiveed joint with the sliding sleeve 12 of shell 4, the endoporus 8-1 that is arranged in the internal gland 8 of shell 4 right-hand members is equipped with internal tooth casing 7, be provided with female splines 7-1 in the endoporus of internal tooth casing 7 right-hand members, spline overcoat 9 is enclosed within the outside of sliding sleeve 12 and internal tooth casing 7, axial teeth groove 4-1 in the external tooth 9-1 of spline overcoat 9 and the shell 4 forms bearing fit, the external tooth 7-2 engagement of the internal tooth 9-2 of spline overcoat 9 and internal tooth casing 7 left ends, compression spring 10 withstands on the left side of spline overcoat 9, one end of pin 14 is captiveed joint with spline overcoat 9, and the other end of pin 14 is positioned at the left side of screw inclined plane 12-1 on the sliding sleeve 12.This spindle nose power-transfer clutch is installed on the automobile of four wheel drive, the spline fitted of the female splines 7-1 of internal tooth casing 7 and automobile half front axle spindle nose, shell 4 is captiveed joint with the propons of automobile.During to muddy bumpy road surface, internal tooth casing 7 drives shells 4 by spline overcoat 9 and rotates at running car, and power-transfer clutch is in engagement state, and the four-wheel of automobile drives simultaneously; When running car during in flat road surface, rotate and regulate turn-knob 1, regulate turn-knob 1 and drive sliding sleeve 12 with respect to shell 4 rotations, screw inclined plane 12-1 pushing pin 14 on the sliding sleeve 12 is to left movement, pin 14 drives spline overcoat 9 and breaks away to left movement and with internal tooth casing 7, this moment, power-transfer clutch was in released state, and vehicle front is a non-driven state.The automobile of installation shaft head clutch has the advantage that oil consumption is low, noise is little, speed is high, mechanical wear is low.Because the internal tooth casing 7 that this spindle nose power-transfer clutch is connected with spindle nose is supported by internal gland 8, so it has prevented radially wobbling of spindle nose; When the spindle nose power-transfer clutch is in engagement state, promoted by a compression spring 10, and promoted by sliding sleeve 12 when being in released state, this structure has that cost is low, simple in structure, the advantage of reliable operation; Because the parts of this power-transfer clutch are installed in the inside of shell 4, therefore when carrying out Motor Maintenance, spindle nose power-transfer clutch integral body can be taken off, it is in place maintain integral installation afterwards, has used very conveniently, has reduced maintenance load simultaneously.
