The 13a of seat portion that fixing half belt wheel 9 and mobile half pulley 11 limit with 13, the axial position of mobile half pulley 11 limits variable ratio automatically centrifugal control gear 14, and pipe sleeve 7 angular velocity are not how.
There is longitudinal hole 15 in live axle 2, and 5 limits conical seats 16 in the end of live axle, and conical seat 16 is coaxial with axis A and hold the corresponding joint part of flange 17, and its flange 17 is connected to internal-combustion engine and locks onto on the live axle 2 through through hole 15 interior screws 18.
Be close to the end 5 of live axle towards centrifugal clutch 8; Live axle 2 is used for the supporting surface 19 of freewheel support 4; Be connected to cylinder blanket 20 and two roller cages 22 in shell 20 on the axle sleeve 7, roller cage 22 has end 21 to connect the end 5 of live axles.
Freewheel support 4 also is disposed axially in the hypervelocity joint 23 between the roller cage 22 in shell 20, hypervelocity joint 23 monodirectional locking devices are as allowing rotation relatively when live axle 2 is faster than axle sleeve 7 rotations; Pin rotation relatively when surpassing live axle 2 when axle sleeve 7 speed, the sense of rotation C that goes out as shown in Figure 2 is consistent with the motor direction, and indicates vehicle running state forward.
The opposition side of flange 17, ball bearing 3 tighten on the end 6 of live axle 2, and lock the shoulder 24 that leans on live axle 2 in the axial direction with screw 18.
Ball bearing 3 in the removable section 25 of axle sleeve 7, and with the radial support of freewheel support 4 at live axle 2 Upper shaft sleeves 7, the end 26 of removable section 25 connects the shoulder 24 of live axles 2.
Axle sleeve 7 is connected on the live axle 2 by means of centrifugal clutch 8 rotatable separation, wherein centrifugal clutch 8 comprise plate support 27, along peripheral a plurality of pawls 28 on the plate support 27, a plurality of drum 29 that is used to interconnect the spring 50 of two adjacent pawls 28 and is locked in plate support 27 on the axle sleeve 7 in nut 25 of being hinged to.
Plate support 27 limits the hole of a plurality of circle distribution and equidistance, the corresponding pin 32 that the hole is parallel with axis A, and limit corresponding hinge axis B, pawl 28 cooperates with drum 29 around hinge axle B rotation.
Each pawl 28 has the rubbing surface 33 of suitable bending radius, is used under the centrifugal acceleration effect and is limited drum 29 and cooperate with the coaxial inner cylindrical surface 34 of axis A.
Each pawl 28 has center of gravity G, and by the inertia motivation sense of rotation that centrifugal acceleration produces, then center of gravity G is positioned at the front of pin 32.If bent axle deviate from pulley arrangement towards, motor counterclockwise rotates and bent axle is connected on the live axle 2 of pulley arrangement, then direction C is counterclockwise, and consistent with the crankshaft rotating direction.
In addition, the position of the bending of rubbing surface 33 and axle B makes the frictional force action line between pawl 28 and the drum 29, relatively between axle B and the inner cylindrical surface 34.
Drum 29 causes when rotating by pawl 28, and centrifugal control gear 14 is connected to a plurality of mobile rollers 36 in induction element 35 and the compartment 37 on the drum 29, and its intermediate compartment 37, is limited at opposite side mobile half pulley 11 in a side by induction element 35.
Mobile rollers 36 between induction element 35 and mobile half pulley 11 radially in, axle sleeve 7 and mobile half pulley 11 are become one in a circumferential direction.
A kind of pulley arrangement of automobile clutch also comprises spring 38 and removable support 39; Its medi-spring 38 axially cooperates with induction element 35; Removable support 39 is connected to mobile half pulley 11 and cooperates with spring 38, is used for separating half belt wheel 11 and fixing half belt wheel 9.
Removable support 39 comprises cylindrical wall 40; Cylindrical wall 40 is connected to the axial end portion of the circumferential part 41 of mobile half pulley 11; Removable support 39 is extended towards the centrifugal clutch 8 of induction element 35; And radial edges 42 is being set with mobile half pulley 11 opposite ends, being defined for the backstop towards axis A of spring 38, spring 38 is in cylindrical wall 40 and in radial edges 42 with towards between the annular seating 43 of the centrifugal clutch 8 of induction element 35.
During static or idling, the pulley arrangement of a kind of automobile clutch of the utility model is shown in an open position when car combustion engine, and its medi-spring 38 keeps fixing half belt wheel 9 to separate with mobile half pulley 11, the maximum speed change/reduction speed ratio of qualification automobile.
After motor car engine was quickened, live axle 2 still was driven in rotation and rotates in static axle sleeve 7.
Live axle 2 continues to quicken, and surpasses the engagement threshold value, and pawl 28 overcomes spring 50 pushings and opens, and contacts with the inner cylindrical surface 34 near the drum 29 of force urges that is produced by centrifugal acceleration.
Therefore axle sleeve 7 passes through frictional force drives with fixing half belt wheel 9, mobile half pulley 11; During operation; Velocity ratio changes by means of mobile rollers 36; And mobile rollers 36 is passed through CENTRIFUGAL ACCELERATING and radial motion on induction element 35, and the pushing force that overcomes spring 38 promotes mobile half pulley 11 towards fixing half belt wheel 9.
