Description

The motorcycle double-clutch engine gear arm

Technical field

The utility model relates to a kind of motorcycle gear box operating mechanism, relates in particular to a kind of gear arm that is used for automatic double-clutch engine of motorcycle.

Background technique

At present, the clutch mode of nearly all motorcycle CG motor all is the manual clutch mode on the market, and when motorcycle carried out variable block under steam, necessary driver was behind the manual control cut-off clutch, and motor just can be shifted gears.When the driver shifts gears at controlling motorcycle, trick cooperates, in manual operating clutch handle, tramp with one's feet and step on change pedal and shift gears, very complicated loaded down with trivial details, and requiring the driver to have sound experience could carry out smoothly, and the neophyty operation difficulty is big, often makes motor impaired because of manual operation is improper.Therefore, be necessary to change the clutch control mode of this motor into automatic clutch, eliminate the step of independent manual operating clutch, make driving simpler, light, and at present the gear arm of manual clutch motor mainly by gearshift axle 1 and go up the positioning spring 2 of suit, first group of plate 3, limiting board 6, reset spring 4 and snap ring are formed (as shown in Figure 1), it only has the gearshift function, can not realize clutch by controlled clutch.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of motorcycle CG automatic double-clutch engine that is used for, and has the gear arm of cut-off clutch, gearshift dual functions.

The technical solution of the utility model is as follows: a kind of motorcycle double-clutch engine gear arm, be set with positioning spring, first group of plate, limiting board, reset spring, packing ring and snap ring on the gearshift axle, described first group of plate and gearshift axle kink, limiting board is fixing with the welding of gearshift axle, it is characterized in that: described first group of plate middle part is provided with the slotted eye of following marginal zone folding arm, first group of set folding arm of plate stretches between reset spring two card bases, and this reset spring is by snap ring locking; Be welded with second group of plate of band " L " shape folding arm on the described positioning spring outer end gearshift axle, the folding arm of second group of plate passes slotted eye and stretches between reset spring two card bases, described positioning spring is fitted between the second group of plate and the first group of plate, and the gearshift axle upper spline second group of plate outer end is set with control arm.

Described slotted eye is arranged on first group of plate central axis, and the folding arm of described second group of plate is positioned at slotted eye central axis place.

The angle α of the left and right sidewall in described slotted eye lower end and its central axis is 15 °-20 °.

Described gearshift axle passes left and right crankcase mounting hole, and the gearshift shaft head inserts the right crankcase cover positioning hole.

Adopt above technological scheme, the five-pointed star that the first group of plate links to each other with speed-changing drum under the pressure of positioning spring is all the time dialled plate and fastens, and owing to cooperates with gearshift between centers crack, with the rotation of gearshift axle.When gear changing by foot, control arm that is connected with gearshift axle spline and the together rotation of gearshift axle, it drives the cam disk rotation, and cam disk to the motion of main clutch direction, promotes the bearing on the main clutch under the tappet roller positioning action, thereby main clutch is separated; Meanwhile, weld second group of fixing plate also with the together rotation of gearshift axle with the gearshift axle, when second group of plate rotates to several angle, be after the main clutch separation is finished, second group of plate extend into first group of folding arm and slotted eye sidewall in the board slot hole and conflicts, stir the first group of plate and rotate, the five-pointed star that the first group of plate stirred on the motor is dialled the plate motion, realizes gearshift.Reset spring sets back after making second group of plate (gearshift axle), the first group of plate finish clutch separation, speed changer variable block.

The beneficial effects of the utility model are: can automatic clutch during engine gear changing, do not need the individual operation clutch, simple to operate, easily, and simple in structure, working stability is reliable, low cost of manufacture.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 2, the utility model mainly is made up of gearshift axle 1, control arm 7, the second group of plate 5, positioning spring 2, first group of plate 3, limiting board 6, reset spring 4, packing ring and snap ring, described first group of plate 3 and gearshift axle 1 kink, its middle part is provided with the slotted eye 3a of following marginal zone folding arm 3b, first group of plate 3 set folding arm 3b stretches between 4 liang of card bases of reset spring, and this reset spring 4 is by snap ring locking; It is fixing with 1 welding of gearshift axle that described second group of plate 5 has " L " shape folding arm 5a, the folding arm 5a of second group of plate 5 passes the slotted eye 3a of first group of plate 3 and stretches between 4 liang of card bases of reset spring, positioning spring 2 is fitted between the second group of plate 5 and the first group of plate 3, by spline housing control arm 7 is housed on the gearshift axle 1 of second group of plate 5 outer end, limiting board 6 is weldingly fixed between first group of plate 3 and the reset spring 4.

Referring to Fig. 3, first group of plate 3 top be with motor on five-pointed star dial the work nest that plate 9 engages, slotted eye 3a is arranged on the central axis at first group of plate 3 middle part, its central axis and first group of plate 3 central axis coincide, the angle α of the left and right sidewall in described slotted eye 3a lower end and its central axis is 18 °, described second group of plate 5 is symmetrical part, and its folding arm 5a is positioned at slotted eye 3a central axis place.

Referring to Fig. 4, Fig. 5, the utility model is packed into behind the crankcase, control arm 7 the other ends that are installed in gearshift axle head head snap among the V-arrangement shift fork 10a of cam disk 10, these cam disk 10 kinks are on the tappet 11 that has three roller 11a, cam disk 10 1 ends are that multidiameter shaft inserts in main clutch bearing 12 center holes, the end face at step place contacts with main clutch bearing 12 end faces, this cam disk 10 with the surface of contact of tappet roller 11a on be evenly equipped with three grooves, three roller 11a on the tappet 11 fall into three grooves of cam disk 10, tappet 11 is provided with locating column 11b and inserts right crankcase cover 8 positioning holes, the central shaft 11c of this tappet 11 passes right crankcase cover 8 and fixes by nut, and tappet 11 leans by roller 11a and cam disk 10.

The utility model is work like this: during gearshift, tramp with one's feet and step on change pedal, change pedal drives gearshift axle 1 by spline and rotates, gearshift axle 1 drives control arm 7 and together rotates, gearshift axle 7 makes cam disk 10 rotations by the V-arrangement shift fork 10a that stirs cam disk 10, because tappet 11 has been fixed, its roller 11a and cam disk 10 grooves misplace, from groove, deviate from, roller 11a forces cam disk 10 to be moved to the left (referring to Fig. 4), cam disk 10 promotes to be installed in the bearing 12 in the main clutch, thereby realize that main clutch separates, this trip is a clutch release travel, gearshift axle 1 angle of swing is 18 °, promptly second group of plate 5 rotates 18 °, then the folding arm 5a of second group of plate 5 stirs 3 rotations of first group of plate, stir five-pointed star by first group of plate 3 and dial plate 9, thereby drive speed-changing drum, realize variable block, variable block rotating distance angle is 14 °, and whole separation gearshift stroke is 32 °, after gearshift finishes, the gearshift axle, the first group of plate is at the effect of reset spring 4 home position next time, and main clutch is combination again under the effect of spring.Because control arm 7 snaps among the V-arrangement shift fork 10a of cam disk 10, control arm 7 positive and negative direction rotations all can drive cam disk 10 rotations, and therefore the gearshift axle can positive and negative direction rotate, and realizes adding, subtracting retaining.
