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.
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 ring-type curved surface groove is the ring-type arc groove, the ring-type circular arc convex tendon face of the rubbing surface of platen and flywheel for matching with the ring-type arc groove.
Described friction clutch, described annular ditch groove quantity are one of 2,3,4,5,6.
Described friction clutch, described annular ditch groove is arranged on the rubbing surface of brake block, and described ring-type circular arc convex tendon 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.
Description of drawings
Fig. 1 driven disc is the clutch sectional structure schematic representation of ring-type curved surface groove.
Fig. 2 driven disc cooperates the clutch sectional structure schematic representation of ring-type circular arc convex tendon for the ring-type arc groove.
Embodiment
As a kind of friction clutch of Fig. 1-2, comprise flywheel 1, the platen 2 of active part, the driven disc 3 of secondary part, the rubbing surface of driven disc 3 arranges at least one annular ditch groove, the face of the rubbing surface of platen and flywheel for matching with annular ditch groove.
Friction clutch as described in Figure 1, described annular ditch groove are ring-type curved surface groove 31, the ring-type curved surface convex tendon face of the rubbing surface of platen and flywheel for matching with the ring-type curved surface groove.
Friction clutch as described in Figure 2, described ring-type curved surface groove is ring-type arc groove 32, the ring-type circular arc convex tendon face 22 of the rubbing surface of platen for matching with the ring-type arc groove, the ring-type circular arc convex tendon face 12 of the rubbing surface of flywheel for matching with the ring-type arc groove.
Described friction clutch, described annular ditch groove quantity are one of 2,3,4,5,6.
Described friction clutch, described annular ditch groove is arranged on the rubbing surface of brake block, and described ring-type convex tendon is arranged on the rubbing surface of brake drum.
