Abstract

The invention discloses a hybrid vehicle and a power transmission system thereof. The power transmission system comprises a coupling mechanism clutch and an executing device, wherein the coupling mechanism clutch is used for connecting or cutting off power transmission between a driving motor and an engine, and the executing device is used for driving the coupling mechanism clutch to be turned on or off and is a linear motor, wherein the linear motor presses or loosens a diaphragm ring of the coupling mechanism clutch to control the coupling mechanism clutch to be turned on or off. In this way, the power transmission system of the hybrid vehicle can shorten the length of a transmission chain, avoids the energy loss of an intermediate transmission mechanism, increases response speed, and improves the reliability of the executing device.

Description

technical field [0001] The present invention relates to the technical field of vehicles, more specifically, to a hybrid vehicle and its power transmission system. Background technique [0002] With the depletion of oil resources and the deterioration of the environment, the development of new energy vehicles has made significant progress. Gasoline-electric hybrid vehicles have the advantages of strong power, energy saving, and environmental protection, and have broad market prospects. [0003] The clutch actuating device of the gasoline-electric hybrid vehicle in the prior art includes an actuating motor and a ball screw mechanism, and the actuating motor drives the ball screw to move, thereby pushing the clutch to close or disengage. [0004] However, the actuator of the clutch in the prior art uses the thrust of the ball screw mechanism to control the opening and closing of the clutch, the transmission chain is long, the response speed is slow, and the performance and rel...
