Abstract

The utility model discloses a rear-located reinforced-separation single-stage automatic clutch of motorcycle which comprises a outsides cover combination, a friction disk combination, a platen combination, and a centre sleeve combination, a forced separation mechanism which is provided between the centre sleeve and the platen combinations; the utility model is provided on the engine main-shaft, which solves the shortcomings of that the single-stage automatic clutch can shift only by the way of returning oil to slow down the engine speed and the vehicle is inconvenient to shift on slope, also the utility model solves the deficiencies of that the structure of the double-stage automatic clutch is complex, the noise is big and the cost is high, etc. But the utility model combines the rear-located automatic clutch and the reinforced-separation mechanism together, which makes the vehicle starts stably and shift freely at any speed during the operation of the vehicle; the device can reduce the operation tiredness and improve the service safety as well as the device simplifies the structure and decreases the cost.

Description

Tailing forced separation one-stage auto clutch of motorcycle

Technical field the utility model relates to a kind of engine clutch for motorcycle, particularly a kind of tailing forced separation one-stage auto clutch of motorcycle.

The existing clutch of motorcycle of background technique is divided into manual clutch and automatic clutch two classes.Manual clutch is normal convolution clutch, the clutch handle of when engine start, must holding with a firm grip, and the loosen the clutch handle could be realized the vehicle smooth starting, also wants the operated clutch handle could realize forcing gearshift during gear shift, complicated operation, use inconvenience.Automatic clutch is owing to be in normally open, needs engine speed to reach just combination behind the certain value, thus needn't the controlled clutch handle, just can realize smooth starting.Existing Motorcycle Automatic Clutch mainly is divided into two kinds again.A kind of is one-stage auto clutch, can be installed on the bent axle or main shaft of motor, when engine gear, all necessary oil return, make engine speed drop to clutch in conjunction with below the rotating speed, could realize gearshift smoothly behind the throw-out-of clutch, its shortcoming is gearshift inconvenience on the ramp.And be installed in that list on the bent axle is forced cut-off clutch automatically since during clutch work rotating speed very high, be subjected to very big influence the working life of clutch, even serious Accident due to quality such as clutch explosion takes place sometimes.Another kind is the twin-stage automatic clutch.It is made up of elementary (one-stage auto clutch) and secondary (Normally closed type clutch).By elementary realization smooth starting, the secondary pressure in gearshift separated, when realizing the motor operation, do not need oil return just can shift gears, therefore, the twin-stage automatic clutch is called two-stage forced gearshift automatic clutch again, the twin-stage automatic clutch has the incomparable advantage of one-stage auto clutch, and its deficiency is that structure is complicated, the bad control of running noise, noise is big, the cost height.

Summary of the invention purpose of the present invention is exactly at the deficiencies in the prior art, and providing a kind of can smooth starting not need oil return just can force to shift gears, do not need to use the tailing forced separation one-stage auto clutch of motorcycle of clutch handle under the arbitrary speed again in the running.

The technical solution of the utility model is as follows: a kind of tailing forced separation one-stage auto clutch of motorcycle, it comprises outer cover combination, friction plate combination, pressing plate combination, central sleeve combination, between central sleeve combination and pressing plate combination, also be provided with the pressure separating mechanism, the supporting base bottom of described pressure separating mechanism is connected in the mesopore of bearing, and bearing fixing is in the mesopore of central sleeve; The spring seat that the top of supporting base is provided with spring seat and push pedal bottom is slidingly matched, Returnning spring place spring seat, among, the cylindrical of supporting base is provided with at least 3 V-shaped seesaw grooves, V-shaped seesaw is slidingly fitted in the seesaw groove by limited ring, and the two ends of seesaw place the bottom of pressing plate and push pedal respectively; Be fastenedly connected with the push rod bearing in the push pedal, the cam disk in the push rod component is fastenedly connected in the mesopore of push rod bearing by the protruding axle of its bottom; The front portion of cam disk is a circular arc, be evenly equipped with at least 3 circular arc depressions on the circular arc from inside to outside, the afterbody of cam disk stretches out, on this extending part, be provided with the gear shift arm connecting groove that runs through, be used to connect the gear shift arm, the center of its upper circular is provided with circular depressed, and depression is slidingly matched with the protruding axle of the bottom of push rod, be evenly equipped with at least 3 corresponding rollers of the recessed position with cam disk or steel ball in the push rod circular outer ends, the middle part of push rod is provided with the adjusting bolt; The edge of the lower plate in the friction plate combination is provided with through hole, and the edge of steel disc is provided with and the corresponding steel disc groove of lead to the hole site, is fixed with spring stack in the hole of lower plate, and release spring is enclosed within on the spring stack, places the steel disc groove of steel disc; Be provided with at least 3 main springs between pressing plate and cover plate, cover plate is by on the jump ring stationary housings.

Steel ball during motorcycle initiating in the clutch outwards moves on inclined-plane, action of centrifugal force lower edge, and the friction plate combination is compressed, and clutch is in bonding state; If need gear shift, step the gear shift arm, the cam disk that links to each other with the gear shift arm rotates, roller or steel ball are descending away from the direction rolling push pedal of depression along the edge, inclined-plane of depression, the end that seesaw contacts with push pedal is descending, the other end that contacts with pressing plate is then up, make pressing plate compression main spring, make between steel disc in the friction plate combination and the friction plate and do not have pressure, between the steel disc of this moment and the friction plate owing to there is not pressure, so can not produce frictional force, thereby steel disc is separated with friction plate, reach clutch separation, cut off the effect of power output; When gear shift arm return, roller or steel ball are got back to the bottom of depression, at this moment, under the effect of the main spring and a spring that resets, the push pedal return, the main spring elongation, under the main spring effect, pressing plate is pressed in the friction plate combination, makes steel disc and friction plate that pressure arranged, thereby make clutch be in bonding state, recover the effect of transmission and output torque.

This tailing forced separation one-stage auto clutch of motorcycle is installed on the engine spindle, solved that one-stage auto clutch has only oil return that engine speed is slowed down could to shift gears and the ramp on shortcoming and the twin-stage automatic clutch complex structure of inconvenience gearshift, big and the high deficiency of cost of noise, it with rear-mounted automatic clutch with force separating mechanism to combine to have accomplished can smooth starting again in the running arbitrary speed force gearshift, simplify the structure, when having reduced cost, can reduce operation fatigue, improve safety in utilization.And this tailing forced separation one-stage auto clutch of motorcycle, owing to be installed on the main shaft, clutch rotational speed is lower during work, has increased the working life of clutch, and can realize forcing to separate, the list that is mounted on the bent axle forces cut-off clutch incomparable automatically.
