Controllable one-way clutch

Abstract

The invention discloses a controllable one-way clutch. The controllable one-way clutch comprises an inner ring, an outer ring, a roller control ring and a roller, and further comprises a control sleeve, wherein rectangular gaps are formed in the two ends of the outer ring to form a separation cavity; the roller control ring is provided with a right-angled trapezoidal limiting block and a roller hole; a separating block in an inverted right trapezoid shape is arranged at the inner circumferential wall of the control sleeve; one side of a bevel of the limiting block and one side of a bevel of the separation block are installed in a separation cavity in a paired manner; a spring is arranged at one side of the right-angled side of the limiting block and abuts against the side wall of the separation cavity; when the separating block axially moves deep into a space between the limiting block and the separation cavity, the limiting block moves to enable the roller not to make contact with theinner ring and / or the outer ring, and thus the one-way transmission function is stopped. The controllable one-way clutch disclosed by the invention can control start and stop of the one-way transmission function thereof and achieves good operation stability.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to a controllable one-way clutch. Background technique [0002] The one-way clutch has two modes of movement: 1. Torque transmission or engagement; 2. Idling or overrunning. Its function is that when the power source drives the passive element, it can only rotate in one direction. If the power source changes direction, such as clockwise If it turns counterclockwise, it will automatically disengage from the function that does not generate any power transmission; or when the power output part of the one-way clutch rotates faster than the power source, the clutch is in a disengaged state, and there is no linkage between the inner and outer rings. This is called a one-way clutch. One-way overrunning function of the clutch. [0003] At present, the commonly used one-way clutches can be divided into two types: roller one-way clutches and sprag clutches. Among them, the controllable one...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned controllable one-way clutch cannot control the opening and closing of the one-way rotation function, and usually can only be transmitted in a certain direction (such as clockwise or counterclockwise), and the direction of transmission cannot be artificially selected, or Realize two-way transmission

There are still some limitations in practical applications
