[0043] Such as Figure 9 As shown, it is the third embodiment of the present invention. The difference from the second embodiment is that the first winding post 33a and the second winding post 33b are composed of a mandrel 34, a bearing 35 and a pulley 36, wherein the bearing 35 sets Placed on the mandrel 34 , the pulley 36 is sleeved on the bearing 35 , and the flexible member 33 c is wound on the pulley 36 . Intermediate pieces 0 are provided at both ends of the mandrel 34 of the first winding post 33 a and the second winding post 33 b , that is, four intermediate pieces 0 are used in each phase winding. When the first transmission member applies a positive torque to the second transmission member, the positive force-applying surface 63 and the positive force-receiving surface 83 press the intermediate piece 0 on the first winding post 33a and the second winding post 33b respectively. , when the first transmission member applies a reverse torque to the second transmission m...

Abstract

A two-way torque transmission device is used for forward and backward torque transmission between two driving components. The two-way torque transmission device comprises a first driving component, a second driving component and at least two windings; wherein the first driving component is provided with a forward force application face and a backward force application face; the second driving component is provided with a forward stress receiving face and a backward stress receiving face; each winding comprises a first wrapping post, a second wrapping post and a flexible element which sequentially winds and wraps the first wrapping post and the second wrapping post; wherein, for each winding, the forward force application face, the backward force application face, the forward stress receiving face and the backward stress receiving face are inserted between the first wrapping post and the second wrapping post; furthermore, the arrangement mode of the winding as well as the forward force application face, the backward force application face, the forward stress receiving face and the backward stress receiving face can realize stress balance.

Description

technical field [0001] The present invention relates to a bi-directional torque transmission device. Background technique [0002] The application number 200720075251.1 utility model patent application submitted by Shanghai Chifeng Electrical Technology Co., Ltd. to the China Patent Office discloses a coupling device. Although the device can realize bidirectional torque transmission, it needs to use two sets of windings, which increases the complexity and cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bidirectional torque transmission device that can transmit bidirectional torque between two transmission parts by only using one set of windings. [0004] In order to solve the above technical problems, the bidirectional torque transmission device of the present invention includes: a first transmission member with a positive force application surface and a reverse force application surface; a second transm...
