Disclosed are a common control apparatus for parking and a clutch, an operating method thereof, and a vehicle. The common control apparatus for parking and a clutch comprises a parking mechanism, a clutch mechanism, and a motor; the parking mechanism comprises a positioning plate, a rotating drum connected to the positioning plate, a cam groove formed on the rotating drum, an elastic positioner, and positioning grooves; the positioning plate rotates under the driving of the motor; the elastic positioner interacts with the positioning grooves; the rotating drum can rotate to positions corresponding to parking lock, parking disengagement, clutch engagement, and clutch disengagement; the clutch mechanism comprises a clutch shifting fork assembly and a shifting fork driving cam; the cam groove comprises a straight groove and an engagement rotation groove; and when the shifting fork driving cam is located in the engagement rotation groove, the engagement rotation groove is engaged with the shifting fork driving cam to drive the clutch shifting fork assembly to move axially. The present invention simultaneously controls the disengagement and engagement of the parking mechanism and the clutch by means of one motor, and the apparatus has the advantages of simple structure, easy manufacturing, low cost, and high efficiency.

Common control apparatus for parking and clutch, operating method thereof, and vehicle

The present invention provides a power system for a hybrid vehicle, relating to the field of hybrid vehicles. The power system for a hybrid vehicle adopts a first planetary gear mechanism with two sun gears, the first sun gear rotates with an input shaft, the second sun gear and the input shaft are independent of each other, and the second sun gear achieves different motion states through a second brake or/and a second clutch, and cooperates with a first brake to provide different transmission ratios of four to six gears when an engine and motors are in driving, so that the power system is simple in structure and low in cost, and the fuel economy and acceleration dynamic performance of the power system are improved.

Power system for hybrid vehicles

A power system for a hybrid vehicle includes a first planetary gear mechanism and a second planetary gear mechanism that cooperate with each other, wherein a first sun gear rotates with a first input shaft, a second sun gear and the first input shaft are independent from each other, the second sun gear achieve different movement states through a first brake, a second brake and a second clutch, to provide different transmission ratios, so that the power system is simple in structure, low in cost and more flexible in adaptability. Further, a second electric motor is connected with the first input shaft through a third planetary gear mechanism, can reduce the speed of the second electric motor through the planetary gear mechanism, and increase the torque, to effectively reduce the size of the second electric motor or improve the acceleration performance of the vehicle.

Power system for hybrid vehicle

A hybrid transmission and a vehicle having the hybrid transmission. An engine, a generator, and a motor are coaxially arranged; a first planetary gear set is separately connected to a crankshaft of the engine and a rotor of the generator; a clutch comprises a first driving end connected to a planet carrier of the first planetary gear set and a second driving end connected to a ring gear of a second planetary gear set, wherein the first driving end and the second driving end are involved in engagement and disengagement; a rotor of the motor is connected to a sun gear axle of the second planetary gear set. When the motor performs driving, the clutch is disengaged from the engine and the generator to avoid a drag resistance of the engine.

Hybrid transmission and hybrid electric vehicle

The present invention provides a power system for a hybrid vehicle, relating to the field of hybrid vehicles. The power system mainly includes an engine, a first motor, a second motor, a first planetary gear mechanism, a second planetary gear mechanism, a first input shaft, a first clutch, a brake, and a second clutch. Since the second motor is connected to the first input shaft through the second planetary gear mechanism, the planetary gear mechanism can reduce the speed of the second motor and increase the torque to effectively reduce the size of the second motor or improve the acceleration performance of the vehicle. Since the first clutch between the first input shaft and the engine is disengaged when driven by the second motor, the drag resistance of the engine is reduced, and the fuel economy of the vehicle is improved.
