Abstract

The invention belongs to the technical field of transmissions, and particularly relates to an integrated planetary mechanism two-gear transmission which comprises a transmission shell, an input shaftand an output shaft. The input shaft is provided with a sun gear and a high-gear cone hub, the output shaft is provided with a planet carrier, and the planet carrier is rotationally connected with a planet gear. A low-gear cone hub is arranged in the transmission shell; the planet gear is sleeved with a gear ring, and the gear ring is located between the high-gear cone hub and the low-gear cone hub; a first synchronous lock ring is arranged between the high-gear cone hub and the planet gear, and a second synchronous lock ring is arranged between the low-gear cone hub and the planet gear; and the first synchronous lock ring and the second synchronous lock ring are located on the two sides of the gear ring and can be meshed with the gear ring through spline teeth, the first synchronous lockring and the second synchronous lock ring are each provided with a positioning part, and the two sides of the gear ring are provided with driving mechanisms. According to the scheme, a planetary mechanism and a synchronizer assembly are combined into a whole, the installation length is shortened, the number of parts is reduced, the rotational inertia of the two ends of a synchronizer is equivalentand small, and the service life of the synchronizer is prolonged.

Description

technical field [0001] The invention belongs to the technical field of transmissions, and in particular relates to an integrated planetary mechanism two-speed transmission. Background technique [0002] Electric vehicles are new, energy-saving and environmentally friendly vehicles, especially in today's environment with severe air pollution, they have great development potential and broad application prospects. An electric vehicle uses an electric motor to replace the engine of a traditional car. The electric motor can be started with load and can meet the requirements of the car through reasonable configuration, which is a big difference from the engine. It is no longer suitable to use multi-speed transmissions on electric vehicles, but in order to take into account the requirements of climbing and high-speed driving, two-speed transmissions are generally used on electric vehicles. [0003] The existing two-speed transmission for electric vehicles is a planetary two-speed ...
