two speed clutch

Abstract

The invention discloses a double-speed clutch, including a box and an oil level regulator, wherein the box includes sealed side walls and end covers installed at two ends of the side walls, the oil level regulator communicates with the interior of the box, and an input shaft, an output shaft, a basic planetary gear set, a high-gear planetary gear set, a low-gear planetary gear set, a friction pair and a gear shifting actuator. The double-speed clutch can be applied to hybrid power and blade electric vehicles, and the variable speed gear shifting function can be achieved by adopting the gear shifting actuator to control the friction pair to perform brake control on the high-gear planetary gear set or the low-gear planetary gear set. The double-speed clutch has the advantages of being capable of achieving unpowered and continuous shifting, quick in switching response, simple in control system, small in structure volume, high in reliability, capable of achieving multiple speed ratio clutch shifting, small in shifting energy consumption, high in transmission efficiency, tiny in neutral gear loss and low in cost.

Description

technical field [0001] The invention relates to the field of vehicle clutch structures, in particular to a two-speed clutch. Background technique [0002] With the continuous development of society, the number of automobiles is increasing, which has caused great pressure on the environment and energy. Therefore, it is urgent to innovate in hybrid technology and pure electric technology to reduce environmental pressure. The innovation of hybrid technology and pure electric technology mainly focuses on two aspects, one is the introduction of energy storage devices, and the other is the introduction of electric drive devices. In order to configure the system more optimally, it is necessary to configure a two-speed automatic clutch to meet the needs of driving conditions. Hybrid or pure electric vehicles have high requirements on the reliability, energy saving and cost control of their clutch devices. For traditional hydraulic torque converters, due to the presence of a contin...
