Abstract

PURPOSE:To abate disturbance in controlling an anti-lock brake system by providing bilaterally asymmetrical circular-arc formed guides for dividing a part of a space part into small areas in the inner and outer peripheral directions extendedly at the side face of a blade. CONSTITUTION:Guides 50a, 50b are provided at high pressure generating parts at the time of normal rotation so as to divide space parts 44 into plural small areas A1, B1 in the radial direction. Accordingly, the flow (a) of a highly viscous fluid at the time of normal rotation flows within the small area A1, so that vortex is not easily generated, generating pressure is doubled, and the pressing force of an operating piston is heightened. At the reverse rotating time of a blade 42, the pressure of large areas A, B becomes high, but the flow (b) of the highly viscous fluid in the large areas A, B flows largely, so that vortex is easily generated, and pressure generation thereby becomes lower in reverse rotation than in normal rotation. Pressure generating characteristic of becoming high or low according to the normal or reverse differential rotation can be thus obtained.

As shown in FIG. 2, the blade 42 extends in the diametrical direction from a rotor 49 that engages the rotating shaft 33 in the rotational direction, and is in sliding contact with the inner circumferential surface of the cylinder housing 32. An arc-shaped guide 50a is provided on the side surface of the blade 42 in the normal rotation direction (or reverse rotation direction), which is asymmetrical to the left and right and partitions a part of the space 44 into a plurality of small areas ^1 and B1 in the inner and outer circumferential directions.

With the above configuration, when the cylinder housing 32 and the rotating shaft 33 rotate differentially, the high viscosity fluid sealed in the space 44 or the blade 42 forces the two close surfaces at a flow rate corresponding to the rotational speed difference. As the cylinder housing 32 moves, internal pressure is generated due to viscous friction with the end face of the cylinder housing 32. That is, for example, in FIG. 2, the cylinder housing 3
In contrast, when the blade 42 rotates counterclockwise in the normal rotation direction, a high pressure is generated on the surface of the blade 42 where the guards 50a and 50b are extended, and an internal pressure with a low pressure distribution is generated on the opposite surface. This internal pressure causes the actuating piston 36 to move into the multi-disc clutch 4.

By the way, in the present invention, the guides 50a and 50b are provided at the high pressure generation site during normal rotation, so that the space 44
is subdivided into a plurality of small areas ^1 and B1 in the radial direction, so the flow a of the high viscosity fluid 27 during normal rotation flows into the small areas 1 as shown in Fig. 2, and a vortex is created. As the pressure is generated, the pressure generated is doubled, and the pressing force of the actuating piston 36 is increased compared to that shown in FIG.

Also, when the blade 42 is reversed, the large areas A and B surfaces of the blade 42 are under high pressure;
The flow b of the high viscosity fluid 27 flows greatly and tends to generate vortices, so that the pressure generated during reverse rotation is lower than during normal rotation.

<Effects of the Invention> As described above, the present invention has a configuration in which an arcuate guide is provided on the side surface of the blade, which is asymmetrical to the left and right and partitions a part of the space into a plurality of small areas in the inner and outer circumferential directions. Therefore, different characteristics of high and low generated pressure can be obtained depending on the forward and reverse directions of differential rotation, and as a result, sufficient torque transmission can be obtained during forward torque transmission, and conversely, when reverse torque transmission is performed, the transmitted torque is limited. This reduces disturbances when controlling the anti-lock brake system.
