Embodiment Construction

[0015] vehicle embodiment

[0016] This embodiment provides a vehicle, including a vehicle body and a pure electric drive system. The vehicle body belongs to conventional technology, so this embodiment will not be described in detail. The following focuses on a detailed description of the pure electric drive system.

[0017] The dual-motor drive system includes a first motor 1 , a second motor 2 , a planetary row, a first lock-up clutch 4 , a second lock-up clutch 5 and a system output shaft 6 . Wherein, the planet row includes three ends, which are respectively called the first end, the second end and the third end. Since the three ends of the planet row are respectively the sun gear 3A, the planet carrier 3B and the ring gear 3C, therefore, the first end, The second end and the third end respectively correspond to one of the sun gear 3A, the planet carrier 3B and the ring gear 3C.

[0018] Such as figure 1 As shown, the first motor 1 is connected to one end of the second l...

Abstract

The invention relates to a dual-motor driving system and a vehicle. The dual-motor driving system comprises a first motor, a second motor, a planet row and a system output shaft, the first motor is connected with a second end of the planet row through a second locking clutch, the second motor is connected with a first end of the planet row and connected with the second locking clutch through a first locking clutch, and the second end or a third end of the planet row is in output connection with a system output shaft. In a dual-motor driving mode, when the first locking clutch is locked and thesecond locking clutch is not locked, the system can output a torque value; when the first locking clutch is not locked and the second locking clutch is locked, the system can output another torque value, and the two torque values are different, so that in the dual-motor driving mode, the pure electric driving system can output two different torques, the output torque can be adjusted according toactual needs, and then the diversity and control flexibility of the working mode of the system are improved.

Description

technical field [0001] The invention relates to a dual motor drive system and a vehicle. Background technique [0002] At present, the pure electric vehicle drive system mainly used in the market is the direct drive form of the motor. This form has a simple structure and layout, but has the following disadvantages: ① The motor that matches the whole vehicle has a large backup torque, and the motor is mostly at low torque and low efficiency in actual use. In this area, the braking and energy recovery effects are poor, and the vehicle economy is not good; ②The cost and weight of the large motor are high, and the matching requirements of the associated cooling system are high, and the competitiveness is weak; ③When the motor fails, the vehicle will lie down directly and cannot Mobile, no emergency backup drive system. In order to solve the above corresponding technical defects, a Chinese utility model patent document with the authorized announcement number CN207790291U disclos...
