Description
Technical field
The utility model relates to clutch field, particularly relates to the self-regualting type clutch of putting induction spring on a kind of.
Background technique
Clutch is arranged between motor and speed changer, is the total member being directly associated with motor in automotive transmission.Conventionally clutch is installed together with the flywheel group of engine crankshaft, is the parts of cut-out and transferring power between motor and automotive transmission.Automobile is from starting to the whole process of normally travelling, and driver is controlled clutch as required, motor is temporarily separated with power train or engage gradually, to cut off or to transmit the power of motor to power train output.Its effect is to make can engage gradually between motor and speed changer, thereby guarantees automobile balance starting; Contacting between temporarily disconnected motor and speed changer, so that impact when gear shift and minimizing gear shift; In the time of automobile emergency brake, can play centrifugation, prevent the transmission system overloads such as speed changer, thereby play certain protective action.
In the long-time application process of clutch, due to driver's repeatedly use, easily make the friction plate being connected with clutch produce wearing and tearing, be offset because the wearing and tearing of friction plate will cause platen, can cause the large end amount of deformation of diaphragm spring to reduce, work impacting force increases, now the required maximum separation power of cut-off clutch also can increase, the strength that makes driver trample clutch requires to increase, and affects the travelling comfort of driving, and has reduced the working life of clutch.
Summary of the invention
Technical problem to be solved in the utility model is to provide the self-regualting type clutch of putting induction spring on a kind of, simple in structure, by the gap that makes clutch energy auto-compensation answer the wearing and tearing of friction plate to produce that is used in conjunction with of induction spring and self-reacting device, guarantee the normal use of clutch.
The utility model solves the technological scheme that its technical problem adopts: the self-regualting type clutch of putting induction spring on a kind of is provided, comprise platen, clutch upper cover and diaphragm spring, described platen is fixedly mounted on the inner side, lower end of clutch upper cover, the inside of described clutch upper cover is furnished with a circle diaphragm spring around the center of circle, the outboard end of described diaphragm spring is connected with clutch upper cover by the trapezoidal supporting rivet of vertically arranging along even circumferential, the outside of described trapezoidal supporting rivet, between clutch upper cover and diaphragm spring, be furnished with annular self-reacting device, described self-reacting device separates and is built-in with elastic component up and down, withstand with clutch upper cover and diaphragm spring respectively all the time at its upper and lower two ends, on the trapezoidal supporting rivet of described clutch upper cover upper-end surface, retaining ring is installed, under the outside of this retaining ring, between edge and the upper-end surface of clutch upper cover, buckle has induction spring.
Described induction spring is annular dish spring, and under the outside of its inner side and retaining ring, along blocking, the projection step covering on outboard end and clutch blocks.
Between described trapezoidal supporting rivet and clutch upper cover for being slidably connected.
Described self-reacting device comprises regulator plate and lower regulator plate, on the relative face of described upper regulator plate up and down regulator plate, be furnished with several tapered wedges along even circumferential, on lower regulator plate, the location arrangements relative with tapered wedges has the inclined-plane matching, on lower regulator plate between adjacent two inclined-planes for adjusting groove, on described upper regulator plate, between two adjacent tapered wedges, block is installed between two parties, a side of described block is connected with a side inwall of adjusting groove by elastic component.
Described elastic component is returning spring.
The lower end of described trapezoidal supporting rivet is furnished with trapezoid block, and the outboard end of this trapezoid block is higher than medial extremity, and the outboard end of described diaphragm spring contacts with the outboard end of trapezoid block.
Induction spring is a belleville spring, it is approximately a zero stiffness spring, its induction elastic force is set to be slightly smaller than the not maximum separation power under abrasion condition of clutch, controlling the size of Separating force, when the friction plate of clutch has after certain wearing and tearing, the large end amount of deformation of diaphragm spring can reduce, its impacting force can increase to some extent, at this time driver needs larger power to carry out cut-off clutch, in the time that Separating force is greater than the power of induction spring setting, trapezoidal rivet will overcome the effect of belleville spring and move axially to platen direction, thereby the fulcrum of diaphragm spring can be moved, lower adjustment plate also moves axially thereupon, at this time two wedges of adjusting between plate can produce certain gap, the frictional force that makes to adjust between plate wedge due to the existence in gap disappears, returning spring now just can pull lower adjustment plate to rotate to overcome this gap, make diaphragm spring get back to again initial mounting point, complete automatic adjustment work.
beneficial effect
The utility model relates to a kind of self-regualting type clutch that induction spring is housed, simple in structure, make diaphragm spring be moved to compensate the gap of answering the wearing and tearing of friction plate to produce by induction spring and being used in conjunction with of self-reacting device, reliable in structure is durable, guarantee the normal use of clutch, extended the working life of clutch.
