Embodiment 1

[0034] Such as Figure 1-9 As shown, a multi-mode clutch includes a clutch body and an actuator;

[0035] The clutch body includes an outer ring 1 and an inner ring 2 arranged coaxially, and a control ring 3 is arranged between the outer ring 1 and the inner ring 2. The outer peripheral surface of the control ring 3 runs through a number of windows 3-1 along its circumferential direction. 3-1 is equipped with a roller 4, and the inner ring wall of the outer ring 1 has a number of cavities 1-1 corresponding to the rollers 4;

[0036] The distance from the middle part of the cavity bottom 1-11 in the cavity 1-1 to the outer wall of the inner ring 2 is greater than the diameter of the roller 4, and the left side 1-12 of the cavity 1-1 is from the cavity bottom 1-11 to the left The side surface 1-12 gradually inclines toward the inner ring 2, and the right side 1-13 of the cavity 1-1 gradually inclines toward the inner ring 2 from the cavity bottom 1-11 to the right side 1-13;

Abstract

The invention relates to the technical field of clutches, in particular to a multi-mode clutch. The multi-mode clutch comprises a clutch body and an execution mechanism, wherein the clutch body comprises an outer ring and an inner ring which are arranged coaxially; a control ring is arranged between the outer ring and the inner ring; a plurality of windows are arranged on the outer circumferentialsurface of the control ring in the circumferential direction in a penetrating manner; rollers are all arranged in windows; an inner circle wall of the outer ring is provided with a plurality of die cavities corresponding to the rollers one by one; a distance from a middle part of the cavity bottom of each die cavity to an outer circle wall of the inner ring is larger than the diameter of each roller; the left side surfaces of the die cavities are gradually inclined toward the inner ring from the cavity bottoms to the left side surface direction; and the right side surfaces of the die cavitiesare gradually inclined toward the inner ring from the cavity bottoms to the right side surface direction. According to the multi-mode clutch disclosed by the invention, along with rotation of the control ring, the rollers positioned on the control ring are respectively positioned in three different working positions in the die cavities so as to realize that the clutch has three working modes; andthrough the execution mechanism, the control ring is driven to rotate by a driving lever, so that free switch of the three working modes of the clutch can be realized.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to a multi-mode clutch. Background technique [0002] The transmission device is generally used to transmit the torque of the active unit to the load. At present, there is at least one clutch in the transmission device to transmit the torque. When the power is input from the input shaft, if the clutch is in the meshing state, the power can be transmitted from the clutch to the output. If the clutch is in a non-engaged state, power cannot be transmitted between the input shaft and the output shaft. Roller clutches The existing roller clutches are usually used as one-way or overrunning clutches to provide certain conditions for the transmission shaft and the output shaft. However, the working mode of this type of roller clutch is relatively single, and its adaptability is poor, so it cannot be applied to transmission devices with complex transmission relationships.
