Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a clutch employed in, for example, an internal combustion engine such as a gasoline engine or a diesel engine.

[Technical background of the invention and its problems]

Conventionally, in clutches used for automobiles,
A known structure is shown in FIGS. 1(a) and 1(b). In other words, in this clutch, one clutch disc 1 is sandwiched between a flywheel 2 and a pressure plate 3, and this is pressed by several springs 4. It transmits power from the input shaft (input shaft) 5 to the clutch shaft (output shaft) 6. The clutch shaft 6 and the clutch disc 1 are fitted together by a spline 7, which allows the reflatch disc 1 to move forward and backward ( axial direction)
It is designed to be able to slide. As shown in FIG. 1(a), when the clutch pedal 8 is depressed as shown in FIG. 1(b) from a state in which the clutch is in operation, the release lever 9 is moved to the release bearing 1.
0, the release lever 11 is pushed down, thereby pulling down the pusher plate 3 against the force of the springs 4. As a result, no frictional force acts on the clutch disc 1, and the power is cut off.

By the way, in racing cars and the like, the magnitude of the power (horsepower, etc.) is changed as appropriate depending on the race. However, with the above-mentioned conventional clutch, when changing the magnitude of the power of the automobile, the entire clutch must be replaced, resulting in poor compatibility, a large number of parts, and difficulty in stocking. In addition, race cars have engines that rotate at over 11,000 revolutions per minute, compared to 5,000 to 7,000 revolutions per minute for ordinary cars, so they produce a lot of noise due to vibrations. However, with the above-mentioned clutch, the weight balance etc. must be adjusted in advance before it is installed in an automobile, and there is a problem that countermeasures against the vibration are troublesome.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and its purpose is to be able to change performance appropriately according to the magnitude of transmitted power, to have good compatibility, and to reduce the number of parts. It requires less and is easy to stock,
Furthermore, it is an object of the present invention to provide a clutch which can be adjusted after being installed in an automobile or the like, and which can easily take measures against vibration.

[Summary of the invention]

In order to achieve the above object, the present invention includes an input shaft and an output shaft arranged on the same axis, a flywheel connected to the input shaft, and an adapter ring detachably attached to the flywheel. a pressure plate that is detachably attached to the adapter ring so as to rotate together with the adapter ring, to be movable in the axial direction, and to be detachable;
By pressing the press plate and a clutch disc that is detachably attached to the output shaft so as to rotate together with the output shaft, to be movable in the axial direction, and to be detachable,
A pressing means that presses the pressing plate, the clutch disc, and the flywheel to transmit power from the input shaft to the output shaft by the frictional force; and a pressure release means for cutting off the transmission of power from the input shaft to the output shaft, and the number of the pressing plates and the clutch discs is changed depending on the magnitude of the power transmitted from the input shaft to the output shaft. By adopting a configuration that allows for power transmission [t11
The feature is that the area can be increased or decreased.

The adapter ring 23 and the cover 24 are removably attached by screws 25 in a superposed state in this order. The adapter ring 23 is made of a magnetic screw comb, aluminum, etc., and is provided with balance holes 26 as shown in FIG. A spline 27 is formed. Further, inside the adapter ring 23, an intermediate plate (pressing plate) 28 and a pusher plate (pressing plate) 29, which are formed in an annular shape from steel, are arranged in this order from the flywheel 22 side. These intermediate plates 28
The butcher plate 29 is fitted into the adapter ring 23 freely in a state in which the splines 30.31 formed on the outer periphery and the splines 27 of the adapter ring 23 are engaged with each other, and are integrated with the adapter ring 23. It is possible to rotate and move in the axial direction.

Further, a clutch shaft (output shaft) 32 connected to a transmission is disposed on the same axis as the crankshaft 21. The tip of the clutch shaft 32 is inserted into the axes of the adapter ring 23, the intermediate plays 1 to 28, and the two pusher plates through a hole 33 formed in the cover 24, and are two clutch discs made of steel34.35
is installed. These clutch discs 34°3
5 is attached to the shaft center by splines 38.39 formed on the inner periphery of the hole 36.37 and the clutch shaft 3.
The clutch shirt 11 is removably fitted onto the clutch shirt 32 in a state in which the spline 40 formed on the outer periphery of the clutch shirt meshes with the spline 40 formed on the outer periphery of the clutch shaft 32, and it rotates together with the clutch shaft 32 and is movable in the axial direction. . Further, the vicinity of the outer periphery of one clutch disc 34 is sandwiched between the flywheel 22 and the intermediate plate 28, and the vicinity of the outer periphery of the other clutch disc 35 is sandwiched between the intermediate plate 2 and the butcher plate 1-29. sandwiched between.

Clutch facings 41 are attached to both surfaces of the clutch disks 34, 35 near their outer peripheries in order to increase the frictional force.

Furthermore, an annular leaf spring 42 is attached to the inside of the cover 24 with bolts 45 and nuts 46, with the radial midway portion being held between annular support rings 43 and 44. , the pressed portion 47 of the pusher plate 29 is attached to the flywheel 2 at its outer circumference.
It is designed to press towards 2. Then, the butcher plate 29, the clutch disc 35, the intermediate plays 1 to 28, the clutch disc 34, and the flywheel 22 are brought into pressure contact, and the frictional force is used to transmit power from the crankshaft 21 to the clutch shaft 32. It has become. In addition, the leaf spring 42 includes:
As shown in FIG. 5, a large number of notches 48 are formed radially from the inner peripheral end to a midway point in the radial direction.
9 can come into contact with it. When the clutch pedal 50 is depressed, the release fork 49 pushes the inner circumferential portion of the leaf spring 42 , thereby causing the outer circumferential portion of the leaf spring 42 to press against the support ring 43 . Flywheel 2 with '44 as the fulcrum
2, and as a result, no frictional force is applied to the clutch discs 34, 35, and the power is cut off.

Furthermore, the number of the clutch discs 34, 35 and the intermediate plates 1 to 28 can be increased or decreased, that is, as shown in FIG. 6, one of the clutch discs 34 and the intermediate plate 28 can be removed, or as shown in FIG. In addition, the clutch disc 51 and the intermediate plate 52
It is possible to add . In addition, clutch disc 34, 35, 51 and intermediate plate 2
The @ theory of 8°52 can be done by removing the screws 25... and replacing the adapter ring 23 with one of a different thickness.

According to the above configuration, when changing the magnitude of the power of the automobile, the clutch disc 3 is adjusted appropriately according to the magnitude of the power.
4. If the number of plates 35, 51 and intermediate plates 1 to 28, 52 is increased or decreased, that is, if the magnitude of the power is small, remove the clutch disc 34 and intermediate plate 28 as shown in FIG. If the number of discs is reduced and the magnitude of the power is large, the power transmission friction area can be increased or decreased by adding or adding a clutch disc 51 and intermediate plays 1-52 to increase the number of discs, as shown in Figure 7. can. Therefore, there is no need to replace the entire clutch, and therefore, compatibility is good, the number of parts is small, and inventory is easy. In addition, after it is assembled into a car, the balance hole 26...
Since the weight balance and the like can be adjusted by providing the above, it is easy to take countermeasures against the vibration.

In the above embodiment, when increasing or decreasing the number of clutch discs and intermediate plates, the adapter ring is replaced with one of a different thickness, but the present invention is not limited to this. For example, the adapter ring is replaced with one of a different thickness. It is also possible to change the thickness and the pressing position by the plate spring, or to use a spring with a large pressing force.
