Problems solved by technology

[0003] Among the existing two-way overrunning clutches, there are mainly roller-type two-way overrunning clutches and wedge-type two-way overrunning clutches, but the functions they realize are the rotation of the active part to realize two-way engagement; the rotation of the driven part to realize the two-way braking function , two kinds of two-way overrunning clutches can not realize the driven part drive, two-way overrunning function

Embodiment Construction

[0013] The slope type two-way overrunning clutch of the present invention includes components such as a driving element 1, an intermediate shaft 2, a friction assembly 3, a driven element 4, steel balls 5, a torque generator assembly 6, a spring 7 and a bearing 9. The active part 1 is connected with the intermediate shaft 2 through the steel ball 5, and the spring 7 presses the intermediate shaft 2 to make it close to the active part 1. The steel ball 5 is installed in the tapered hole on the end surface of the active part 1 and the intermediate shaft 2 . The other end of the intermediate shaft 2 is connected to the torque generator 6 through splines, and is associated with the driven member 4 through the friction assembly 3 in the middle area. The friction assembly 3 is composed of a dynamic friction plate and a static friction plate, the static friction plate is connected with the intermediate shaft 2 through a spline, and the dynamic friction plate is connected with the dri...

Abstract

The invention relates to a two-way overrunning clutch capable of realizing two-way driving of a driving piece, two-way joint of a driven piece, two-way driving of the driven piece and two-way overrunning of the driving piece, in particular to a spherical slope type two-way overrunning clutch. In a traditional two-way overrunning clutch, a rolling column type two-way overrunning clutch and a wedgedblock type two-way overrunning clutch are mainly provided, and both achieve the functions of realizing two-way joint through rotation of the driving piece and realizing two-way braking through rotation of the driven piece; and the two two-way overrunning clutches cannot achieve the function of two-way overrunning through driving by the driven piece. A driving piece and an intermediate shaft are coaxially mounted in a shell; multiple conical holes, distributed in the peripheral direction, are formed in opposite disc surfaces of the driving piece and the intermediate shaft; under the effect ofa spring, the intermediate shaft clamps a steel ball between the driving piece and the intermediate shaft; and the intermediate shaft and the driven piece are associated through a friction module. Thespherical slope type two-way overrunning clutch is novel in structure, prevents accidental joint under the vibration impact condition, and achieves the fault-tolerant capability.

Description

technical field [0001] The invention relates to a two-way overrunning clutch capable of realizing two-way driving of an active part and two-way engagement of a driven part; two-way driving of a driven part and two-way overrunning of an active part, in particular to a ball slope type two-way overrunning clutch. Background technique [0002] There are two working modes for opening the cargo door, one is electric opening and the other is manual opening. On the premise of confirming that the manual opening is driven by a flexible shaft, how to solve the problem of how to solve the problem of manually turning the flexible shaft without adding additional manual operations, so that the product can automatically realize the joint function and transmit torque to open the cargo door. At the same time, during the electric opening process, the product automatically surpasses, and the flexible shaft does not rotate. [0003] Among the existing two-way overrunning clutches, there are mai...
