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

Embodiment Construction

[0020] Embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0021] Such as Figure 1-8 As shown, a selectable clutch includes: an inner ring coupling sleeve 6, an outer ring coupling sleeve 7, a spline hub 14, an inner ring ring gear 2 and an outer ring ring gear 3, and the feature is: the spline hub 14 is provided with Two integrated coaxial inner ring spline hubs 15 and outer ring spline hubs 16, the outer ring coupling sleeve 7 is provided with an outer ring coupling sleeve that matches the spline teeth 35 of the outer ring spline hub. The spline teeth 33 are sleeved on the spline hub 16 of the outer ring, and the inner ring coupling sleeve 6 is provided with the inner spline teeth 32 of the inner ring coupling sleeve matching with the spline teeth 34 of the spline hub of the inner ring, and is installed on the inner ring The inner ring coupling sleeve installation groove 23 between the spline hub 15 and the ou...

Abstract

The invention discloses a selectable clutch. The selectable clutch is provided with an inner ring combining sleeve, an outer ring combining sleeve, a splined hub, an inner ring gear rim and an outer ring gear rim, and is characterized in that the splined hub is provided with an inner ring splined hub and an outer ring splined hub which are integrally and coaxially sleeved and embedded, and a linkage gear for the inner ring combining sleeve and the outer ring combining sleeve is arranged on the outer ring splined hub and between the inner ring combining sleeve and the outer ring combining sleeve, and an inner ring combining sleeve transmission rack and an outer ring combining sleeve transmission rack meshing with the linkage gear for the inner ring combining sleeve and the outer ring combining sleeve are axially arranged on the inner ring combining sleeve and the outer ring combining sleeve, so that the outer ring combining sleeve moves towards a direction opposite to the direction pushed by the external force by linking with the inner ring combining sleeve when being pushed by the axial external force of the selectable clutch, the inner ring combining sleeve can be selectively sleeved with or separated from the inner ring gear rim, and the outer ring combining sleeve can be selectively sleeved with or separated from the outer ring gear rim. The selectable clutch disclosed by the invention has the advantages of small size, 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...
