Abstract
A friction clutch comprises a fly wheel, a pressure plate and clutch plates, wherein the fly wheel and the pressure plate belong to a driving part, while the clutch plates belong to a driven part; one or more annular grooves are formed in the friction surfaces of the clutch plates; and the friction surfaces of the pressure plate and the fly wheel are matched with the annular grooves. According to the utility model, as the grooves are formed in the friction surfaces of the clutch, friction area is enlarged; and great friction force can be generated without great treading force or oil pressure, and friction of the pressure plate with relatively large diameter, so that size and cost of the friction clutch can be reduced; as for that the annular trapezoid grooves are matched with annular trapezoid convex ribs, the average width value of the annular trapezoid convex ribs is slightly larger than that of the annular trapezoid grooves when the annular trapezoid grooves are completely clung to the annular trapezoid convex ribs (the included angles of the annular trapezoid grooves and the annular trapezoid convex ribs are the same), so that the grooves can generate great gripping force when the annular trapezoid convex ribs move forwards slightly, as a result, friction force can be transmitted effectively, and the size and cost of the friction clutch can be further reduced.
Description
Technical field
The utility model be in the car transmissions directly and the parts that interrelate of motor, specifically be exactly a kind of friction clutch.
Background technique
Clutch is cut-out and the combination that it is being responsible for power and transmission system, so gentle start can guarantee vehicle starting the time, smooth-going in the time of also guaranteeing to shift gears also prevented the transmission system overload.
Clutch is used for cutting off the power with engage engine.Clutch is a driving mechanism, it has active part and secondary part, two-part can temporarily separate also slowly combination, and in transmission process, also might produce relative rotation, so, can rely on contact friction to transmit moment of torsion between the driving link of clutch and the driven member, or utilize the needed impacting force torque delivery of friction.
Widely used on automobile at present is exactly the friction clutch that leans on spring compression.Automobile needs often to keep the transmission of power in the process of travelling, interrupting power is temporary transient needs, so active in the process of moving and secondary part are in bonding state for a long time, when driver's let slip the clutch, by the transmission of parts, allow secondary part separate with active part.
Along with the number of used rubbing surface, also there is a lot of differences the form of holddown spring and mounting point, and the operating mechanism difference of travelling.Number by driven disc is divided into single plate clutch and double plate clutch.Wherein single plate clutch mainly is used on car and the pick up truck, and the moment of torsion that double plate clutch transmits is bigger, in therefore being mainly used in, heavy goods vehicles.Structural type according to holddown spring is divided into coil clutch and diaphragm spring clutch again.
Each clutch all is made up of following part: (1) active part: flywheel, platen, clutch cover etc.; (2) secondary part: driven disc, driven shaft (being clutch spindle); (3) pressing section: holddown spring; (4) operating mechanism: separator levers, separator levers bearing post, rocking pin, release sleeve, release bearing, clutch pedal etc.
The working procedure of clutch can be divided into separation process and engaging process: in separation process, let slip the clutch is at first eliminated the free clearance of clutch in free travel, produce Separation, clutch separation then in working stroke.In engaging process, release the clutch pedal gradually, platen moves forward under the effect of holddown spring, at first eliminates Separation, and in platen, driven disc and the enough impacting forces of flywheel working surface effect; Release bearing is mobile backward under the effect of Returnning spring afterwards, produces free clearance, and clutch engages.
Platen is the driving part of clutch, all the time with the flywheel rotation, can pass through boss, key or pin transmission usually, and itself and flywheel are together rotated, and platen can move backward relative to flywheel again simultaneously, makes clutch separation.Driven disc mainly is made up of driven disc body, friction plate and clutch plate hub.
The modal compressing structure of friction clutch is exactly helical spring and diaphragm spring, and diaphragm spring clutch has pushing-type and pull-type two kinds of structural types.And coil clutch is divided into all cloth springs and central spring according to the mode that spring is pressed on the platen.
The rubbing surface of existing friction clutch all is the plane, wants to reach enough big frictional force, will increase friction area, so existing friction clutch diameter is all bigger, causes the volume ratio of friction clutch bigger, makes cost increase.
Summary of the invention
In order to reduce the volume of friction clutch, reduce the cost of friction clutch, the utility model provides a kind of friction clutch.
The utility model is achieved in that a kind of friction clutch, comprises flywheel, the platen of active part, the driven disc of secondary part, and the rubbing surface of driven disc arranges at least one annular ditch groove, the face of the rubbing surface of platen and flywheel for matching with annular ditch groove; Described annular ditch groove is the ring-type trapezoidal groove, the ring-type trapezoidal convex tendon face of the rubbing surface of platen and flywheel for matching with the ring-type trapezoidal groove.
Described friction clutch, the numerical value of the mean breadth of the trapezoidal convex tendon of described ring-type is greater than the numerical value of ring-type trapezoidal groove mean breadth.
Described friction clutch, described annular ditch groove quantity are one of 2,3,4,5,6.
Described annular ditch groove is arranged on the rubbing surface of brake block, and the trapezoidal convex tendon of described ring-type is arranged on the rubbing surface of brake drum.
The rubbing surface of clutch of the present utility model is established groove, has increased friction area, does not need big stampede power or oil pressure.Need not use the bigger platen friction of diameter yet, just can produce big frictional force, just can reduce the volume of friction clutch, reduce the cost of friction clutch.Cooperate the trapezoidal convex tendon of ring-type for the ring-type trapezoidal groove, when the trapezoidal convex tendon of ring-type trapezoidal groove and ring-type is adjacent to fully (the two angle is identical), because the numerical value of trapezoidal convex tendon mean breadth is less times greater than the numerical value of V-shape groove mean breadth, trapezoidal convex tendon moves forward a little again, groove just produces huge clamping force, can effectively transmit frictional force, further reduce the volume of friction clutch, reduce the cost of friction clutch.
