Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a transmission device including a belt transmission for engine driving and power transmission of automobiles, agricultural machinery, construction machinery, ships 3 and others; In particular, it relates to a V-speed power transmission for an automobile.

するウェット （オイル）方式がとり入れられている。(Prior Art) Recently, various proposals have been made for so-called CTV systems (belt transmission systems) for automobiles, and among them, a metal block belt in which the upper and lower ends of a steel band are secured with metal blocks is used. However, in order to prevent wear and noise caused by contact between the metal block and the metal boob, and to ensure smooth drive, a wet (oil) system is used to lubricate between the belt and pulley.

れるに至った。However, in this method, the groove of the speed change pulley has a structure with a smooth surface, so when the belt is running, especially when running at high speed, it is easy to form an oil film between the contact surface between the belt side surface and the pulley groove, and the gap between the belt and the pulley. The friction coefficient of the belt decreases, making it easier for slips to occur against large torques.Therefore, in order to prevent this slip, the tension of the belt is increased.
It was necessary to increase the contact pressure between the belt and the pulley. Therefore, by increasing the tension generated in the belt,
In order to withstand this, it becomes necessary to greatly increase the strength of the belt, and the volume of the belt becomes thicker (at the same time, various problems arise, such as load on the pulley bearings and loss of heat generation due to belt friction). has come to be pointed out.

The purpose is to prevent the formation of an oil film between the belt and pulley and maintain a high coefficient of friction even under such conditions.

高水準に保持することができる。FIG. 7 is a schematic diagram showing one embodiment of the transmission device of the present invention (Dr.
) is a driving speed change pulley (Dn) configured such that a porous material having a large number of pores (H) is arranged along both sides of the groove.
Like (Dr), is a driven variable speed pulley with small holes (H) in the groove surface, and between these two pulleys is a ■-shaped block belt or rod with high lateral rigidity as shown in Figures 4 and 5 above. A V-bell l-(B) with a cog is wrapped around it. Therefore, the belt (B) is driven in the direction of the arrow, and as the belt runs, oil (mainly lubricating oil) is injected from the nozzle (N) mainly to the back of the belt and, if necessary, to the sides of the drive and driven pulleys. As a result, the heat generated in the belt and pulley during running is absorbed, and the oil that separates during rotation is scattered around, and some of it remains and adheres to the pores (H) on the contact surface of the belt and the pulley. This allows for smooth running, but since the porous material has many pores that communicate with each other, it prevents oil from accumulating at the bottom of the belt in the pulleys when more oil adheres than necessary. Since a channel is formed and oil flows out through the channel by centrifugal force, the amount of oil remaining in the pores of the contact surface between the belt and pulley is minimized, and by holding it in this way, the oil film is cut. , the friction coefficient between the belt and the pulley can be maintained at a high level by reducing slip.

Only one of (Dn) may be a porous surface pulley, or both may be used. Furthermore, a porous surface variable speed pulley and a normal ■ pulley (either a porous surface or a normal smooth surface pulley) may be used. A combination is also possible.

This is the place to do it.

うな結果を得た。A porous sintered alloy is provided in the groove part of the V-pulley of the present invention, and when a belt consisting of blocks made of FRP are connected by bolts to the upper and lower parts of the neutral belt is hung and stretched, and the belt is run, the y Qg part is different from that of the conventional one. The difference in the coefficient of friction between the steel with a smooth surface and the porous surface of the present invention was determined by the method shown in FIG. 9, and the results shown in FIG. 8 were obtained.

できる顕著な効果があることが判明した。That is, Fig. 9 shows the state in which oil is injected from the nozzle (N).
A test piece (b) made of the same material as the ■-shaped block belt (FRP reinforced by mixing epoxy resin with glass fiber) was loaded (F ), and by varying the pressure contact load, the surface pressure is determined from the relationship with the contact area of the test piece, and the sliding speed is 0. The torque generated on the rotating shaft at 15 m/see was determined and the dynamic friction coefficient (μ) was measured. As is clear from Fig. 8, the results of the present invention (1) in which a porous member is placed on the side surface of the pulley have a great effect of scattering and releasing the oil generated at the contact surface of the V-belt and the pulley, and reduce the oil film on the pressure contact area. It is possible to maintain a high coefficient of friction of about 0.09 to 0.14 μm, and achieve the required surface pressure and belt tension with smaller surface pressure and belt tension compared to conventional smooth surface pulleys (0.05 to 0.06 μm). It has been found that it has the remarkable effect of exerting transmission force, improving the durability of the belt and bearing part, and significantly reducing loss of transmission force.
