Abstract

The invention provides a shared actuator of a clutch and a parking mechanism. The shared actuator comprises a driving motor and a tooth arc, a driving gear is arranged on the driving motor, driving teeth matched with the driving gear are arranged on the tooth arc, the driving gear is meshed with the driving teeth so that the driving motor drives the tooth arc to rotate, a first pin hole and a second pin hole are formed in the tooth arc, the first pin hole is rotatably connected with a parking actuating rod, the second pin hole is rotatably connected with a clutch driving rod, the parking actuating rod is used for driving the parking mechanism, and the clutch driving rod is used for driving the clutch. According to the actuator, separate driving of the clutch and the parking mechanism can be achieved through one driving motor, the need for a set of driving equipment is eliminated, the lightweight design of the vehicle is facilitated, after the parking mechanism is locked and the clutchis engaged, the driving motor is not needed to run continuously, the costs and energy consumption are saved, and the time spent on parking action and clutch engagement can be further reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an actuator shared by a clutch and a parking mechanism. Background technique [0002] The transmission of a hybrid vehicle usually uses a clutch to integrate the engine into the drive system, so that the engine can be directly driven by the engine when the vehicle is running at high speed, so as to improve the fuel economy of the vehicle. This kind of clutch is generally controlled by hydraulic cylinder actuators, and hydraulic actuators need to be equipped with hydraulic pumps, proportional pressure solenoid valves, valve plates and other components to provide hydraulic power, thus resulting in hydraulic actuators. The cost of clutch components is high and the power consumption is large, so it is more suitable for occasions where multiple clutches can share the oil pump. For scenarios with only one or two clutches or brakes, hydraulic actuators are not suitable because the ...
