Problems solved by technology

The friction plate clutch has a large volume, so it will have an adverse effect on the miniaturization of the transmission. At the same time, the friction plate clutch relies on the friction force of the friction plate to transmit torque, and the transmission torque is limited by the limit value of the friction force of the friction plate. limit, thereby limiting the transmission torque of the clutch

Abstract

An optional clutch, comprising: an inner ring coupling sleeve, an outer ring coupling sleeve, a spline hub, an inner ring ring gear and an outer ring ring gear, and is characterized in that the spline hub is provided with two integrated coaxial sleeves The spline hub of the inner ring and the spline hub of the outer ring, on the spline hub of the outer ring, there are interlocking gears for the coupling sleeve of the inner ring and the coupling sleeve of the outer ring, and the coupling sleeve of the inner ring and the coupling sleeve of the outer ring respectively The outer ring coupling sleeve is axially provided with an inner ring coupling sleeve transmission rack and an outer ring coupling sleeve transmission rack that can mesh with the inner and outer ring coupling sleeve linkage gears, so that the outer ring coupling sleeve is subjected to an external force along the axial direction of the optional clutch. When pushing, the coupling sleeve of the inner ring is linked with the reverse movement of the external force, so that the coupling sleeve of the inner ring and the ring gear of the inner ring, and the coupling sleeve of the outer ring and the gear ring of the outer ring can be selectively fitted or separated. The invention has the beneficial effects of small volume, large bearing torque, strong impact resistance, high transmission efficiency and simple structure.

Description

[0001] Technical field [0002] The invention relates to a selectable clutch, which belongs to the technical field of mechanical transmission, in particular to a clutch structure of an automobile transmission. Background technique [0003] The parts that switch forward and reverse gears in automatic transmissions usually use two friction plate clutches (such as CVT continuously variable transmissions), which are used to select and switch between two rotating parts in opposite directions . The friction plate clutch has a large volume, so it will have an adverse effect on the miniaturization of the transmission. At the same time, the friction plate clutch relies on the friction force of the friction plate to transmit torque, and the transmission torque is limited by the limit value of the friction force of the friction plate. limit, thereby limiting the transmission torque of the clutch. Contents of the invention [0004] In order to overcome the above-mentioned disadvantage...
