Double-input end transmission and driving device using same

Abstract

The invention discloses a double-input end transmission. A first input shaft (110) and an output shaft (1A0) are coaxially arranged; the first input shaft (110) and a second input shaft (150) are arranged in parallel on the two sides of an intermediate shaft (130); a first input end (111) and a second input end (151) are arranged on two opposite side surfaces of a transmission shell (1C0); the double-input end transmission further comprises a first gear (120), a second gear (160), a third gear (140), a fourth gear (180), a fifth gear (190), a first gear shifter (1B0) and a second gear shifter (170). The double-input end transmission solves the problems that the existing electric motor coach driving device is complicated in structure and high in cost, and is mainly applied to the field of motor coach driving devices.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a double-input transmission and also to a driving device using the same. Background technique [0002] At present, automobile emission has become one of the main factors of environmental pollution. In order to protect the environment and reduce automobile emission, the development of hybrid electric vehicles and pure electric vehicles has become one of the important means to solve environmental problems. [0003] The main functional requirements of hybrid electric vehicles are: 1. The internal combustion engine and the motor can work independently; 2. The internal combustion engine and the motor can work together; 3. When driving, the internal combustion engine can drive the motor to generate electricity; 4. When parking, the internal combustion engine can drive the motor to generate electricity; 5. 1. When braking, the motor can generate electricity and recover energy; 6. When parki...

Problems solved by technology

[0004] For example, Chinese Patent No. "ZL201220648667.9" discloses a hybrid transmission. When the hybrid transmission is applied, the motor is arranged behind the transmission. In order to meet the ability of the motor to work alone, the motor needs to reserve a large power, and the internal combustion engine Unable to drive the motor to generate electricity

[0005] For example, Chinese Patent No. "ZL200920140428.0" discloses a drive system for hybrid electric vehicles. The main feature of this system is that the motor is installed between the transmission and the clutch. The motor is limited by this space, and the motor has poor versatility and high development costs. , and the system increases the axial length compared with the traditional structure, which makes the layout of the whole vehicle difficult

[0006] For example, Chinese Patent No. "ZL20061003547.9" discloses a hybrid electric vehicle with automatic transmission. Two motors are added to the hybrid electric vehicle, one of which replaces the speed changer. The acceleration capability is limited, and two high-power motors are required. The total power of the system is about twice that of a traditional car, which increases the cost of the vehicle. The high-power motor means high-power discharge, which affects the life of the battery and increases the axial length, making vehicle layout difficult

[0007] At present, pure electric vehicles are mainly directly driven by motors. Taking a full-loaded 18-ton 12-meter bus as an example, the rated power of commonly used motors is about 100KW, and the maximum torque is about 2700Nm. The gradeability that can be satisfied is only 15%. Poor; and the cost of high-power motors is high and the size is large, making it difficult to arrange the vehicle; in order to reduce the cost of the vehicle, more asynchronous motors are used. When directly driving the climb, the power factor of the asynchronous motor is lower than 0.5. The capacity of the inverter is large, the loss is also large, and it is difficult to start
