Problems solved by technology
For example, when the active part is reversed, the power of the active part cannot be transmitted to the driven part, that is, when using a one-way overrunning clutch, the active part cannot reversely transmit power to the driven part, so it cannot be applied in both forward and reverse directions. power occasion

The invention provides a combined tri-state overrunning clutch which comprises a unidirectional overrunning clutch and a tri-state overrunning clutch which are combined together. The two clutches share the same outer ring and the same inner ring; the wedging directions of the wedges in the two clutches are opposite. The unidirectional overrunning clutch is provided with the unidirectional overrunning state and the joint state; the tri-state overrunning clutch is provided with the unidirectional overrunning state, the joint state and the bidirectional separation state. Accordingly, the combined tri-state overrunning not only has the operating states of a common unidirectional overrunning clutch, but also has the bidirectional separation state and the bidirectional joint state; thereby, thetri-state overrunning clutch is in the overrunning or joint state.
Description
Technical field The invention relates to a combined three-state overrunning clutch. Background technique Ordinary overrunning clutch is also called one-way overrunning clutch or one-way bearing, which is a device that can only transmit torque in one direction of rotation. The existing overrunning clutches mainly include roller type overrunning clutches and wedge type overrunning clutches. As an example of a wedge type overrunning clutch, CN 2476675Y (or CN 1430000A) discloses a one-way overrunning clutch with a double cage. The one-way overrunning clutch includes an inner ring and an outer ring. A plurality of wedges are arranged in between, and these wedges are held by holding holes opened in the double cage (including the inner cage and the outer cage) between the inner ring and the outer ring. In this one-way overrunning clutch, by using a double cage structure, the load-bearing capacity of the one-way overrunning clutch can be improved and its service life can be prolonge...
