Embodiment 1

[0030] see figure 1 As shown, Embodiment 1 of the present invention provides a kind of hybrid power transmission comprising engine 1, motor 5, planetary gear mechanism 9 and output shaft 18; The first clutch 6 is arranged between the crankshaft 2 of engine and the rotor 51 of motor, uses It is used to connect or disconnect the crankshaft of the engine and the rotor of the motor, that is to say, the engagement or disconnection of the first clutch enables the connection or separation between the crankshaft of the engine and the rotor of the motor; the rotor of the motor and the planetary gear mechanism There is a second clutch 7 between them, which is used to engage or disconnect the rotor of the motor and the planetary gear mechanism, that is, to connect or separate the rotor of the motor and the planetary gear mechanism 9; the planetary gear mechanism 9 is used to connect The power input by the engine and / or motor is transmitted to the output shaft, that is, the engine transmi...

Embodiment 2

[0047] The hybrid transmission in the second embodiment is an improvement on the basis of the first embodiment. The technical content disclosed in the first embodiment will not be described repeatedly, and the content disclosed in the first embodiment also belongs to the content disclosed in the second embodiment.

[0048] see figure 2 As shown, in this embodiment, the hybrid transmission also includes a fourth clutch 13 and a reverse gear input shaft 14, the reverse gear input shaft is connected to the crankshaft of the engine, and the first transmission end of the fourth clutch is connected to the reverse gear of the planetary gear mechanism. The sun gear is connected, and the second transmission end of the fourth clutch is fixedly connected with the reverse gear input shaft, wherein the first transmission end of the fourth clutch can be engaged or disconnected from the second transmission end of the fourth clutch. Engagement of the fourth clutch enables the reverse gear in...

Embodiment 3

[0052] The hybrid transmission in the third embodiment is an improvement on the basis of the second embodiment. The technical content disclosed in the second embodiment will not be described repeatedly, and the content disclosed in the second embodiment also belongs to the content disclosed in the third embodiment.

[0053] see image 3 As shown, in this embodiment, the planetary gear ring gear further includes a large gear 933; the internal gear, the large gear and the pinion are fixed together and rotate coaxially. The diameter of the large gear is larger than the diameter of the small gear.

Abstract

The invention relates to the technical field of automobiles, in particular to a Hybrid transmission and vehicle using the same . The hybrid transmission comprises an engine, an electric motor and an output shaft of a planetary gear mechanism; A first clutch is arranged between the crankshaft of the engine and the rotor of the electric machine for engaging or disengaging the crankshaft of the engine and the rotor of the electric machine; A second clutch and a third clutch are provided between the rotor of the motor and the planetary gear mechanism for engaging or disengaging the rotor of the motor and the planetary gear mechanism to achieve four to six shifts. The hybrid vehicle of the invention comprises the hybrid transmission, which can reduce the drag resistance of the engine to the electric motor when the electric motor is driven, and improve the fuel economy; At that same time, the engine and the electric motor can be simultaneously use for driving, so that the acceleration pow performance of the vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hybrid transmission and an automobile using the transmission. Background technique [0002] A HEV is generally a vehicle powered by a prime mover using two different energy sources: a conventional internal combustion engine (ICE) using liquid fuel and an electric motor (EM) powered by battery power. There are many different ways to incorporate power from an electric motor into a vehicle's powertrain. The current popular hybrid electric vehicle adopts a dual-motor power distribution transmission scheme (such as patent CN107298016A), which requires simultaneous control of two motors to adjust the speed, which not only has high manufacturing costs, but poor acceleration performance (depending on the small torque in the motor and engine), And because the motor has to work at many inefficient speeds (such as low speed or high speed), and when working electrically, the engine ha...
