Abstract

PURPOSE:To form an engine to small size and light weight, by building a one- way clutch in a multiple disc friction clutch and suppressing transmission of torque to a side of the engine at deceleration. CONSTITUTION:At deceleration running operation, a one-way clutch 20 is placed in a disengaged condition, and torque in the side of a rear wheel is not transmitted to a clutch center 6. Accordingly, although the torque in the side of the rear wheel is transmitted to the side of a clutch outer 3 through a clutch center 5, two sheets of clutch plates 7 engaged to the clutch center 5 and three sheets of clutch discs 4 frictionally engaged to the clutch plates 7, a slip is generated because of a less number of sheets of the engaged clutch plates 7 and the clutch discs 4 contributing to the transmission of the torque. As a result, brake force of an engine is not so increased more than necessary.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a multi-plate friction device used in motorcycles, etc., in which the engine 11 is moved from the rear wheel under G during deceleration.
This is related to a multi-disc friction clutch that can reduce the amount of torque that can be transmitted.

This is because the I-, 'YuNi;ton engine has a high-speed rotation type output 1', +i property.

However, when the reduction ratio is increased, a large amount of engine braking force is applied during deceleration driving or when driving is stopped, but conversely, the torque due to the rotational inertia of the rear wheels is increased. However, the engine side becomes over-revved. Therefore, normally, in order to alleviate the engine's overspeed k 1iJj , +1c engine's engine overspeed k 1iJj ,+1c, in order to improve the engine's ilt f':l:
In addition to disposing an intermediate shaft between the rear wheel shaft and the clutch, a one-way clutch (1J) for slipping the intermediate shaft is installed to transfer the torque transmitted from the rear wheel side.

However, in order to limit the transmission torque, the intermediate Hilt
If 1 is installed, the engine becomes larger and the engine size increases accordingly.

The present invention relates to an improvement of the conventional technology that was devised in consideration of the above circumstances, and by incorporating a one-way clutch into the multi-disc friction clutch, transmission is transmitted from the rear 1ha+ side to the engine side during deceleration. The aim was to suppress the generated torque and at the same time reduce the size and weight of the engine.

1. Boss γ? A 1:3 bearing is fitted to the li 1.1a.

Next, the operation of multi-disc friction clutch I will be explained. The clutch l is connected and disconnected by lifter rods l' and 11. In other words, one of the old lifter rods! 7il (left at the 11th threshold (1ij end;

2-1 Off-shore force (moves outward in opposition to this, and the multiple clutch discs 11 and clutch plate 7, which were held under strong pressure between the pressure plate 11 and the clutch center 5, are depressurized, Clutch 9J becomes disconnected.

When the lifter JRADO is displaced in the opposite direction to the direction indicated in 11u, the pressure plate DOOR moves inward due to the elastic restoring force of the rough spring 12, and multiple plates are moved between it and the clutch center 5. Strong pressure is applied to the clutch disc 4 and clutch plate 7, and the clutch Jg is connected to the clutch position P.

When the engine is running, the rotation of the clutch outer shaft 2 is transmitted from the drive gear 31 to the driven gear 2 of the multi-disc friction clutch 1, and the clutch outer 3, which is integrally connected to the driven gear 2, rotates 11 ( If the multi-plate friction clutch 1 is in the connected state, 1 clutch clutch 3
Power is transmitted to the clutch plate 7 that frictionally engages with the clutch disc 4 that engages with the plurality of grooves, and the clutch center 5.6, pressure plate +4, and lifter plate 13 rotate externally. In this state, −

This oil is supplied into the main shaft 40 and is discharged to the gears on the main shaft through a plurality of openings/IOa, and is also supplied to the multi-disc friction clutch 1. The first oil supply path that appears in the multi-disc friction clutch 1 is as follows: -IJ

In this way, lubricating oil is guided through the gate ntt 1 through holes etc. carved in each component system of the multi-disc friction clutch 1. This effectively lubricates the inside of the clutch 1. In particular, the C- direction clutch 2 is effectively lubricated through the washers 10a and II.
0, one-way clutch 20 using spring set member 8 which holds clutch center 6 and holds pressure pre=1.1/1 via bellows spring 12, and washer 1 (la). Since the lubricating coil is supplied, it is possible to sufficiently lubricate the one-way clutch 20.

Next, the state of zero during traveling at speed σIN or until the vehicle stops will be explained. During deceleration driving, so-called engine braking is applied, and due to the rotational inertia of the rear wheels, the rotational speed on the main shaft 40 side is reduced by the clutch outer 3I.
Because it is larger than T11I, the clutch edge center 6 side rotates relative to the one-way clutch 20 in the direction opposite to the arrow in FIGS. 3 and 7, causing a roller-like state!
Next, J124 rotates a little so that the flat surface 2.1c meets the inner peripheral surface of the clutch center 6, and the one-way clutch 20 is disconnected. −
If so, no torque will be transmitted to the rear wheels. Therefore, the torque on the rear wheel side is generated by the clutch center 5, the one clutch plate 7 that engages the latch center 5, and the three clutch discs 4 that frictionally engage with the clutch plates 1 and 7. Pass the clutch outer 3 through the 1. However, since the number of engaged clutch plates 7 and clutch discs 4 that contribute to torque transmission is small, slip roughness occurs. In general, the torque from the rear wheel that exceeds the I and vibration forces obtained by the engagement of fj'J is released in the multi-disc friction clutch I.
be. As a result, the engine braking force is less than necessary. G does not become too large, and over-rotation is effectively prevented.

In this example, the Mi pressure play 1, 1, 1 is placed outside of the clutch setter 5.6 and inside of the lifter play 13 (=J force A-ru spring). 1
