Clutch capable of selecting modes

Abstract

The invention discloses a clutch capable of selecting modes. The clutch comprises an actuator and a clutch mechanism, the actuator and the clutch mechanism are fixedly connected together, and thus theactuator drives the clutch mechanism to move simultaneously when moving; the actuator comprises a sliding block and a shifting rod which are detachably fixed together, and thus the sliding block drives the shifting rod to move simultaneously when moving; the clutch mechanism comprises an inner seat ring, an outer seat ring, a control ring, a first locking block and a second locking block; the inner seat ring and the outer seat ring are arranged coaxially, and the first locking block and the second locking block are arranged between the inner seat ring and the outer seat ring; the shifting rodis inserted into a groove opening of the control ring of the clutch mechanism, and thus linear motion of the shifting rod is converted into rotation motion of the control ring; and the control ring can rotate around the outer seat ring under driving of the shifting rod, and thus the first locking block and the second locking block are controlled to rotate.

Description

technical field [0001] This invention relates to a clutch for an automatic transmission, and more particularly to a selectable mode clutch. Background technique [0002] Clutches are an important part of automatic transmissions. Traditional wet friction clutches have large volumes, large drag torque losses, large flow requirements for cooling and lubrication, and require high pressure for control. For automatic transmissions Tank pumps and hydraulic systems are demanding, increasing fuel consumption and costs. [0003] Compared with the wet clutch, the traditional one-way clutch can achieve the same lock-up torque with a smaller size of the one-way clutch and a smaller flow requirement for cooling and lubrication. However, the one-way clutch can only realize rotation in one direction and locking in the other direction, and cannot realize free rotation in two directions and locking in any one direction. At the same time, there is still a drag torque loss in the process of ro...

AI Technical Summary

Problems solved by technology

However, the one-way clutch can only achieve rotation in one direction and locking in the other direction, and cannot achieve free rotation in two directions and locking in any one direction. At the same time, there is still a loss of drag torque during the rotation process.

[0004] The electrification and electrification of the automobile industry is an unstoppable trend. At the same time, the hydraulic drive of the clutch needs to increase the high-pressure control. It is necessary to design the high-pressure oil circuit of the hydraulic valve plate, and increase the original components such as the pilot valve pressure regulating valve and the electromagnetic pressure regulating valve. The hybrid transmission also needs to be equipped with an electric oil pump, which increases additional costs
