Abstract

The invention provides a hybrid transmission for road vehicles and belongs to the technical field of power transmission systems. The hybrid transmission comprises an engine, a motor MG1, a motor MG2, a planetary gear train P1, a planetary gear train P2, a brake B1 and a brake B2; during running of the motors, the brake B2 is closed, the two motors can run simultaneously or independently for slow or reverser gear driving of the vehicles; during running of the engine, the brake B1 is closed, the motor MG1 is used for speed regulation in medium- and high-speed driving of the vehicles; the motors can recycle energy when the vehicles slow down. By the transmission, powered shifting can be realized, coaxial dynamic input and output can be achieved, the hybrid transmission is entirely simple in the form, compact in structure, high in transmission efficiency and capable of improving dynamic performance of the vehicles to a great extent, thereby improving fuel economy of the vehicles.

Description

technical field [0001] The invention relates to the technical field of power transmission systems, in particular to a hybrid transmission for road vehicles. Background technique [0002] At present, energy shortage has become an important problem facing the world, and hybrid technology can effectively improve low-speed power output and fuel consumption of vehicles, and has become the development direction of the automobile industry. Road vehicles (such as city buses) often work at low speeds and start-stop conditions. Under low-speed and start-up conditions, they can be driven by motors. Under deceleration conditions, the motors can recover braking energy. Charge the battery, which can greatly improve the fuel economy of the vehicle. [0003] In the literature on the design of hybrid transmissions, manufacturers such as Honda, Toyota, Geely and Corun have not realized the coaxial input and output mechanism of the transmission, and there will be a problem that the radial ins...
