Abstract

The invention discloses a mechanical double overrunning clutch self-adaptive automatic transmission output by a planetary system, which adopts a planetary gear system to output power, and the transmission system includes a low-speed transmission mechanism, a reverse transmission mechanism and an adaptive transmission assembly; the reverse transmission mechanism has The transmission ratio I for transmitting the power of the reverse gear from the subshaft to the main shaft, and the low gear transmission mechanism has a transmission ratio II for transmitting the power of the low gear from the subshaft to the main shaft, and the transmission ratio I is greater than or equal to the transmission ratio II; the present invention utilizes two overriding The reasonable cooperation of the clutch makes the overall structure simple and compact, and the reverse gear transmission shares the transmission line with the low gear and fast gear transmission without interference, which ensures the overall performance, strong adaptability, and smooth and natural cooperation with the adaptive automatic transmission mechanism. The planetary deceleration output is used to increase the output torque, and a high-speed motor can be used as the power source to improve the overall efficiency. It is not only suitable for the field of electric vehicles, but also suitable for other variable torque mechanical transmission fields.

Description

Planetary output mechanical double overrunning clutch adaptive automatic transmission technical field The present invention relates to a kind of motor vehicle transmission, particularly a kind of mechanical double overrunning clutch auto output of a planetary system [0001] Adapt to automatic transmission. Background technique Mechanical transmission system generally uses complex working conditions, needs to distribute torque to realize the transmission of different loads and rotational speeds, to Taking electric vehicles as an example, the driving environment is complex and changeable. And the electric drive method commonly used in the existing electric vehicles is the motor drive fixed The speed ratio, high efficiency and reasonable range are narrow and limited, resulting in a vicious circle, resulting in the following problems: [0003] 1. It can only work within the torque range of a certain working condition. [0004] 2. In order to meet the road conditions under ...
