Embodiment Construction

[0057] The present invention will be described in further detail below according to accompanying drawing and embodiment:

[0058] Such as figure 1 , figure 2 As shown, the sprag clutch 100 of the present invention includes a driving cam 6 , a driven element 1 , at least one centrifugal sprag 3 , at least one reset device 110 and an intermediate support 2 . The driving cam 6, the intermediate support 2 and the driven element 1 are arranged on the same axis, the intermediate support 2 is hinged to the driving cam 6, the intermediate support 2 and the driven element 1 are arranged radially apart from each other, and a plurality of centrifugal wedges 3 surround the intermediate support 2 The axis of the drive cam 6 and the driven element 1 are arranged in turn, and each centrifugal wedge 3 is respectively movable and installed on the middle bracket 2, and the driving cam 6 pushes the centrifugal wedge 3 to move radially, so that the centrifugal wedge 3 and The driven element 1 ...

Abstract

The invention discloses a wedge-type clutch. The clutch comprises a driving cam, a driven element, at least one centrifugal wedge, at least one reset device and a middle support, wherein the middle support is hinged with the driving cam; the middle support and the driven element are mutually spaced for a certain distance in the radial direction; a plurality of centrifugal wedges are sequentially arranged between the driving cam and the driven element around an axis of the middle support; each centrifugal wedge is respectively movably arranged on the middle support; the centrifugal wedges are driven by the driving cam to radially move to ensure that the centrifugal wedges are in contact with the driven element and torque is transmitted; and the reset devices are used for continuously applying an acting force on the centrifugal wedges to ensure that the centrifugal wedges and the driven element are kept in a non-contact state. The clutch disclosed by the invention is strong in load capability and good in impact resistance and can have excellent performances of both one-way / two-way clutches; and the cultch disclosed by the invention can be used for realizing the power transmission and separation functions between prime motors and working machines or between driving elements and driven elements in machines and can be used in the mechanical drive fields of automatic transmissions and the like.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to a sprag clutch. Background technique [0002] In the prior art, a clutch is a common component in mechanical transmission, which can separate or engage the transmission system at any time. Friction clutch is the most widely used type of clutch. It is basically composed of four parts: active part, driven part, pressing mechanism and operating mechanism; the main, driven part and pressing mechanism are to ensure that the clutch is in the engaged state and can The basic structure of power transmission has smooth engagement and good wear resistance, and the clutch operating mechanism can quickly and completely disengage the clutch at any time, but it is not suitable for applications on equipment that frequently disengages, and there is no overrunning function that will cause inertia loss of power. The one-way clutch is composed of an outer race, an inner race, a cage, a wedge, etc...
