Example Embodiment

[0017] In the following, the concept, specific structure and technical effects of the present invention will be further described in conjunction with the accompanying drawings to fully understand the purpose, features and effects of the present invention.

[0018] See figure 1 , 2 Shown is a schematic diagram of the structure of a preferred embodiment of the present invention. The present invention relates to a high-performance new energy electric multi-speed transmission, which includes a motor 1 that outputs power to a driving shaft 4, and the driving shaft 4 is equipped with a gear Driving gear 41, second-speed driving gear 42 and third-speed driving gear 43. The first-speed driving gear 41, the second-speed driving gear 42, and the third-speed driving gear 43 are coaxially spaced apart, the first-speed driving gear 41 meshes with the first-speed counter gear 51, the second-speed driving gear 42 meshes with the second-speed counter gear 52, and the third-speed The driving gear...

Abstract

The invention relates to the technical field of vehicle transmission devices, in particular to a high-performance new energy electric multi-gear transmission. The high-performance new energy electric multi-gear transmission comprises a motor. The motor outputs power to a driving shaft. The driving shaft is provided with a first-gear driving gear, a second-gear driving gear and a third-gear driving gear. The first-gear driving gear is engaged with a first-gear driven gear of a driven shaft. The second-gear driving gear is engaged with a second-gear driven gear of the driven shaft. The third-gear driving gear is engaged with a third-gear driven gear of the driven shaft. The driven shaft is further provided with a driven output gear and gear shifters. The driven output gear is engaged with a differential transmission gear on a differential assembly, and the differential assembly outputs power to a wheel. The gear shifters are driven by a spiral gear shifting mechanism. The spiral gear shifting mechanism drives the gear shifters to shift gears based on spiral trajectories. According to the high-performance new energy electric multi-gear transmission, gear shifting is made more smooth and accurate, abrasion to a gear-shifting structure is reduced, the impact to the motor is reduced, working loads of the motor are also reduced, the service life is prolonged and power saving is realized; and the high-performance new energy electric multi-gear transmission can be used for being connected to an electric vehicle rear axle, and control is easy, convenient and safe.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission devices, in particular to the technical field of gear shifting for electric vehicles. Background technique [0002] With the development of science and technology, electric vehicles have the advantages of low-carbon environmental protection and economical savings. During the driving of the electric vehicle, the user generally changes gears as needed to obtain different speeds. However, in the shifting structure of the electric vehicle in the prior art, the manual shift fork is mainly used to directly drive the gear shifting combination teeth to realize the shifting. This structure has a large impact on the motor during use, and the motor is prone to burnout, and The shifting structure wears quickly and the service life is short. [0003] For this reason, the applicant upholds the spirit of research, innovation and excellence, and uses professional vision and professional knowledge t...
