Abstract

The invention provides a hybrid drive system with a hydraulic torque converter, which comprises a motor, the hydraulic torque converter, a planetary row, a planetary carrier clutch, a planetary carrier brake and a drive motor, wherein the motor comprises a crank; the crank is connected with a pump wheel of the pump wheel clutch, a worm wheel of the hydraulic torque converter is connected with the pump wheel through a lockup clutch of the hydraulic torque converter; a sun wheel of the planetary row is connected with the worm wheel; a planetary carrier of the planetary row is connected with a gear ring of the planetary row through the planetary carrier clutch; the planetary carrier brake is arranged to be used for braking the planetary carrier; and a rotor shaft of the drive motor is connected with the gear ring. The hybrid drive system provides a larger output torque when a vehicle is started for accelerating or climbing, reduces the requirement on a drive motor system and an electrical storage device, and meets the requirement on high dynamic property of a heavy vehicle.

Description

technical field [0001] The present invention relates to the technical field of drive systems, in particular to the technical field of vehicle hybrid drive systems, and specifically refers to a hybrid drive system with a hydraulic torque converter, which is especially suitable for heavy vehicles. Background technique [0002] In recent years, heavy vehicles such as city buses with hybrid drive systems have been increasingly used. A hybrid drive system used on a heavy-duty vehicle that is primarily used as a production tool must have high dynamics to increase the vehicle's production efficiency and be able to use it on a variety of terrains, for example, It is used in mountainous cities with long and steep slopes. Specifically, high standoff acceleration and gradeability (including maximum gradeability and sustained gradeability) are basic requirements for hybrid drive systems of heavy vehicles. [0003] For example, Chinese patent 200720006546.3 discloses a hybrid electric ...
