Abstract

PURPOSE:To control power transmission through simple structure by providing a flow passage for making working oil in a volume chamber formed by vanes or the like communicate with another volume chamber to make the working oil transmit the rotation of a casing to a rotor shaft, and providing the above flow passage with a valve to stop or control the flow rate of the working oil. CONSTITUTION:In the case of the straight advancing and starting of a car having no rotary speed difference between a side of engine rotation and a tire side, a spool valve 14 is throttled to make the rotation on both the above sides more identical in speed, and when a handle steering angle exists, the spool valve 14 opens each of volume chambers 12 and makes them communicate with each other. Thus an allowable range is given to the rotary speed difference to eliminate power loss due to the tight cornering phenomenon of a car and the slipping of a tire. The above mentioned control of the valve 14 can be automatacally executed in connection with a sensor to detect the rotation of the engine and an angle of steering wheel.

従来の粘性クラッチとしDETAILED DESCRIPTION OF THE INVENTION As an embodiment of the present invention, a device is provided that efficiently distributes and transmits torque to the drive wheels while absorbing the rotational difference between the engine output and the drive wheels when the vehicle is running. There is a clutch (joint) that uses viscous silicone oil that combines many plates, but due to its nature, it has a locking property, and the torque at the beginning of slipping is large and the torque transmission rate after friction occurs is poor. In addition, the torque transmission rate changed depending on the difference in outside temperature, so the function as a drive distribution device for automobiles was insufficient. The transmission structure is shown in Figure 1, which is a front and plane cross-sectional view.
2) Sequence (2) when transmitting torque from the rotor (3) with the internal vane (1) to the rotor shaft (4)
) Each vane has an eccentric volume chamber created by a cam ring on the inner surface (if it is limited by one vane and cannot respond to the volume change of the fluid, that is, if there is no flow path opening amount, there will be no difference in rotation between each other and torque transmission Figure 3
．． 4 is a sectional view showing the speed change mechanism when a rotation difference occurs between the sequence shaft (5) and the rotor shaft (4) due to the opening of the flow path. The fluid in the volume chamber defined by the vane (1) is
(3) The rotor shaft (4), which also serves as a spool valve, is guided by a flow path, and the spool valve is opened and closed by operating the rotor shaft (4) as shown in the arrow (7). At that time, each volume chamber pressure Since it can respond to changes, it is possible to control the rotational difference and torque transmission, so it performs the function of a continuously variable transmission, and has the characteristic of maintaining the driving shaft against overload and unloading of the wave shaft.
As a conventional viscous clutch
