Abstract

PURPOSE:To improve the cooling effect of a friction plate by flowing a lot of lubricating oil while declutched or half-clutched so as to increase the flow of lubricating oil by the volume of a vacant space. CONSTITUTION:While separator plates 10 and 10' are prevented from being brought in contact together, a lot of lubricating oil flows in between the two separator plates 10 and 10' as shown with an arrow mark from a lubrication oil hole 22 of a driven gear 16 while the clutch is released or half-released in power transmission. Particularly, the flow of lubricating oil is increased by the amount of flowing through oil sump formed between the two separator plates 10 and 10'. Therefore, the generation of heat is restricted low during continuous running with the half-released clutch and the cooling effect is improved.

As shown in FIG. 6, this separator plate is formed of a ring-shaped annular plate 5 and a plurality of engaging parts 6 that protrude radially on the outer periphery of the annular plate 5, and is located between the retaining parts 6 of the annular plate 5. In the wet type clutch shown in Fig. 7 using this separator plate 8, the waves 7 are formed as shown in Fig. 8 when the power is cut off. As shown in the figure, the friction plate 3 is not deformed at all, and the top of the wave 7 is in slight contact with the top of the wave 7. During power transmission, the friction plate 3 is pressurized in the axial direction by the piston 9, and the wave of the separator plate 8 is 7 is pinched between adjacent friction plates 3 and its height is gradually reduced,
Finally, the entire annular plate 5 is located in the same plane, and the separator plate 8 and the friction plate 3
are in close contact with each other, and power is transmitted by the frictional force between the two. Friction plate 3 by piston 9
When the pressure in the axial direction is released, the elasticity of the waves 7 reliably separates the friction plate 3 from the separator plate 8, regardless of the adhesive force of the lubricating oil, cutting off the power transmission. Therefore, the clutch can be easily disengaged, and the generation of drag frictional heat is eliminated.

, IO', a large amount of lubricating oil flows between them. As a result, the flow rate increases by the amount that passes through the oil pool formed between the two separator plates 10, 10'. Therefore, heat generation during continuous operation in a half-clutch state is suppressed to a low level, and the thermal load due to clutch fading is significantly reduced. Also, the natural energy that one separator plate should absorb can be reduced to half.

(Effects of the Invention) As can be seen from the above explanation, the wet multi-disc clutch of the present invention has
It has a plurality of engaging parts projecting radially on the outer periphery of the annular plate,
Two separator plates that form waves protruding in the plate thickness direction between the engaging parts are moved between the friction plates by shifting the positions of the engaging parts on the outer periphery so that the crests and troughs of the waves face each other. Since it is assembled to the drive side drum, when power is transmitted, the two separator plates come into close contact with each other, and at the same time, the two separator plates 1 and 2 securely come into contact with the adjacent friction plates, and the high Ig friction force causes the power to be transmitted. When the power is cut off, the elasticity of the waves reliably separates the friction plate from the separator plate and cuts off the power, regardless of the adhesive strength of the lubricating oil, and at the same time prevents the separator plates from adhering to each other. Drag torque can be reduced. Therefore, the clutch engages and engages very well, and there is no generation of drag frictional heat.

In addition, the Type 18 multi-disc clutch of the present invention opens the lubricating oil hole of the wave-side gear towards the center between the two separator plates, so when power transmission is interrupted or the clutch is half-way,
A large amount of J lubricating oil flows in, and the flow rate increases as it passes through the oil pool formed between the two separator plates. Therefore, the heat generated between the separator plate and the friction plate during continuous operation in the t-clutch state is suppressed to a low level, the heat load of clutch fading is significantly reduced, and the thermal energy that should be absorbed by one separator plate is halved. Therefore, the cooling effect of the separator plate and thus the friction plate is improved, and the yI slip is performed well, thereby improving the durability of the friction plate and the durability of the clutch as a whole.
