Fig. 1-5 is please referred to, the utility model provides a kind of technical solution:

A kind of clutch shifter assembly, as shown in Figure 1, existing including crankshaft 1, the flywheel 2 for being mounted on 1 one end of crankshaft, setting The clutch disc 3 of 2 side of flywheel, the platen 4 that 3 side of clutch disc is set, the diaphragm spring 5 that 4 side of platen is set, peace Mounted in 5 side of diaphragm spring clutch case 6, be arranged at 6 center of clutch case release bearing 7, be connected to release bearing 7 The shift fork 8 of one end and the transmission input shaft 9 for being plugged on 7 side of release bearing.

In the present embodiment, crankshaft 1 is in-engine output shaft, provides power, flywheel 2 is bolted on crankshaft 1 One end, flywheel 2, clutch disc 3 and platen equal 4 use gray cast iron, and hardness strength is high, and heat conductivity is good, high-wearing feature, increases Add service life.

In the present embodiment, clutch case 6 is bolted to connection with flywheel 2, and clutch case 6 passes through with diaphragm spring 5 Rivet is fixedly connected, and riveting will relax, and diaphragm spring 5 at riveting, as supporting point, by lever principle, to realize to platen 4 It drives, diaphragm spring 5 is bolted to connection with platen 4.

In the present embodiment, one end of release bearing 7 is equipped with block 70 and is engaged by clamping with idler wheel 81, the tail of release bearing 7 End is equipped with spring 71, and release bearing 7 and spring 71 are successively socketed on transmission input shaft 9, and the internal diameter of release bearing 71 is greater than The outer diameter of transmission input shaft 9 does not rotate with it to keep loosening.

In the present embodiment, one end of transmission input shaft 9 is equipped with spline and mating with spline 31.

In the present embodiment, clutch disc 3 is gray cast iron material, and hardness strength is high, and heat conductivity is good, high-wearing feature, is increased Add service life, clutch disc 3 and spline 31 are integrally cast, firmer.

As shown in Figure 2, Figure 3 and Figure 4, the surface of 2 side of flywheel is equidistantly equipped with several circular grooves 1, at 2 center of flywheel Equipped with counterbore 21, the side of clutch disc 3 is equipped with several balls 1, and the other side of clutch disc 3 is equidistantly equipped with several Circular groove 2 30 is equipped with spline 31 at 3 center of clutch disc, and the side of platen 4 is equipped with several balls 2 41.

In the present embodiment, circular groove 1 and circular groove 2 30 are engaged by clamping with ball 1 and ball 2 41 respectively, ball one 32 and ball 2 41 press merga pass screw sealed by fixinig plate 1 and fixinig plate 2 40 respectively.

In the present embodiment, fixinig plate 1 and fixinig plate 2 40 cannot be projected into outside surface while fixed ball, be kept away It is impaired to exempt from friction.

As shown in figure 5, shift fork 8 includes shift fork handle 80, one end of shift fork handle 80 is equipped with axis hole 800, the front end of shift fork handle 80 Equipped with notch 801, idler wheel 81 is installed in notch 801.

In the present embodiment, shift fork 8 is in Y-shaped, and shift fork 8 is gray cast iron, and intensity hardness is high, increases service life, shift fork Handle 80 and axis hole 800 are integrally cast, so that stabilized structure, axis hole 800 is fixed in speed changer box shell by axis, play branch The effect of support point, and then realize lever principle, idler wheel 81 is fixed by a pin in notch 801, and the aperture of idler wheel 81 need to be greater than The outer diameter of pin rolls idler wheel 81 freely.

At work, driver tramples clutch pedal to the clutch shifter assembly of the present embodiment, by that will come from clutch The power of pedal acts on shift fork 8, since axis hole 800 is fixed in speed changer box shell by axis, when 8 bottom end stress of shift fork to When outer mobile, the idler wheel 81 mounted in 8 top of shift fork will pass through the support of axis hole 800 and move inwards, since idler wheel 81 is fastened on In block 70, release bearing 7 can be pushed to squeeze diaphragm spring 5, so that release bearing 7 no longer squeezes diaphragm spring 5, thus 4 disconnecting clutch piece 3 of platen is driven, the transmission from 2 power of flywheel is interrupted and realizes that separation is put into gear；It is stepped on when driver unclamps clutch When plate, since the active force that shift fork 8 is subject to reduces, as the screen resilience of diaphragm spring 5 pushes 7 return of release bearing and limits In 71 front end of spring, while platen 4 squeezes fitting clutch disc 3 by diaphragm spring 5, and ball 2 41 rolls on 3 surface of clutch disc It moves until sliding into circular groove 2 30, the ball 1 of clutch disc 3 is rolled on 2 surface of flywheel until sliding into circle at the same time In slot 1, that is, realize engaging, clutch disc 3 is clamped by flywheel 2 and platen 4 and drives rotation, to make to be plugged on spline 31 In transmission input shaft 9 rotate, power transmission can be realized, compression engage with circular groove by ball, the drive rotation of clutch disc 3 Work of changing a job since ball coefficient of friction is small to slow down frictional heating phenomenon, decreases the ash that rubbed, so that clutch It is inside cleaner, the close normal cooperating of each part, by installing idler wheel 81 in the front end of shift fork 8, reduce shift fork 8 with separate The friction of 7 joint of bearing, extends the service life of shift fork 8, reduces 3 skidding probability of clutch disc.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Be only the utility model preference, be not intended to limit the utility model, do not departing from the spirit and scope of the utility model Under the premise of, the utility model also has various changes and improvements, these changes and improvements both fall within claimed it is practical In novel range.The protection scope of the present invention is defined by the appended claims and their equivalents.
