り、これが本考案の目的である。 In construction vehicles and cargo handling vehicles, the rotation of the main engine is used, such as a normal wet multi-disc clutch that frequently slips the clutch for slow-speed operation or work on site, or a clutch that drives a generator by the main engine of a ship. In order to provide a constant rotational speed to the generator even if the speed varies due to external conditions such as when entering and departing a port, during navigation, and during operation, it is also necessary to use a constant rotational speed such as the drive clutch of a water pump or boiler blower. There is a variable speed clutch device that continuously slips the clutch in order to provide an output rotation speed that matches the required flow rate from the prime mover.If the clutch plate is frequently or constantly in the slip state as described above, friction loss will be converted into heat. Therefore, if there is a part where the supply of cooling lubricating oil is insufficient, the temperature of the clutch plate in that part will rise and there is a risk of seizure. Therefore, it is possible to prevent seizure by supplying a large amount of lubricating oil, but as the amount of circulating oil increases, the power cost increases and the clutch plate sways, making it difficult to control the low output rotation speed. The disadvantage is that it becomes unstable. In order to achieve the best cooling effect with the minimum amount of lubricant required, it is important to distribute the lubricant as evenly as possible between each clutch plate, and this is the object of the present invention.

のクラツチ板の焼付きが防止された。 In the clutch plate of such a clutch device, normally the lining material 9 of the output clutch plate 8 is provided with an oil groove 27 as shown in FIG.
Only the lining materials 9 1 and 9 2 of the output side clutch plate 8 1 and 8 2 in contact with the bucking plate 1 and backing plate 12 have their oil grooves removed to provide smooth surfaces. By eliminating this oil groove, the amount of lubricating oil circulated between each clutch plate row is now averaged, whereas in the slip condition the amount of lubricating oil circulated was concentrated at both ends of the clutch plate row and decreased in the middle. This prevents the clutch plates, especially the middle clutch plate, from seizing up.

る。 The carrier 6 shows the state of circulation of lubricating oil between the clutch plates 8 1 and 8 2 when oil grooves are provided in the lining materials 9 1 and 9 2 as in the past, and when they are removed as in the present invention. Figures 4 and 5 show the results obtained by detecting the temperature of the oil flowing out from the outer periphery using temperature sensors arranged in the axial direction on the outer periphery. The horizontal axis of the figure shows the positions where the temperature sensors are arranged in the axial direction from the clutch piston 11 side to the bucking plate 12 side along the oil hole 28 on the outer periphery of the carrier 6, and the vertical axis shows the position of the temperature sensors detected by the sensors. It shows the difference between the temperature of the spilled oil and the temperature of the supplied oil. First of all, Figure 4 shows a comparison when changing the amount of oil while keeping the slip rate of the clutch constant. Curve a shows the conventional case, and curve b shows the oil grooves in the outer lining of the clutch plates at both ends. Regarding the case of the present invention, the subscript 1 of a and b indicates when the amount of oil supplied to the clutch plate is small, and the subscript 2 indicates when the amount of oil supplied to the clutch plate is large.

つている。 Looking at Figure 4, when the oil level is low, the conventional clutch plate shows a large temperature difference in the middle part.
a 1. There was a risk of seizure in the clutch plate in the middle, but by eliminating the oil groove on the surface of the friction plate that contacts the clutch piston and bucking plate as in the present invention, the peak in the middle can be almost eliminated. Suddenly b 1
The effect is clearly visible. Next, when the amount of oil increases, both curves a 2 and b 2 decrease and approach each other, but b 2 is smaller overall than a 2 .

い。 Figure 5 shows the effect of changing the slip rate while keeping the amount of oil supplied constant. The intermediate peak becomes larger in the order of c 1 , c 2 , and c 3 . That is, if the amount of heat generated increases due to a change in slip, there is a risk that the clutch plate may seize. On the other hand, in the case of the present invention, as shown by curves d 1 , d 2 , and d 3 , even if the slip ratio changes, the overall curve is low and smooth, and the clutch plate does not seem to seize locally. Nothing happens.

率の小さいときに効果的である。 As mentioned above, the present invention has the effect of preventing the clutch plate from seizing during slippage by simply eliminating the oil groove in the lining material of the clutch plate on the surface that contacts the clutch piston and bucking plate. . This is particularly effective when lubricating oil is low and the slip ratio is low.
