Abstract

The invention relates to a transmission. The transmission is characterized in that hydraulic oil enters into a first oil transportation passage and a second oil transportation passage through a firstcircular groove and a second circular groove which are formed in an input shaft, and the hydraulic oil is transported to a first friction disk controller or a second friction disk controller through the first oil transportation passage or the second oil transportation passage, the first friction disk controller is matched with a first driving gear or the second friction controller is matched witha second driving gear, and the first driving gear or the second driving gear starts rotating. According to the transmission, the oil transportation passages of the hydraulic oil are arranged in the input shaft, the structure of the transmission is simplified to reduce the size of the transmission, the oil transportation passages of the hydraulic oil can be prevented from external interference, andthe hydraulic controlling manner of the friction plate controllers is adopted as a clutch controlling manner, so that gear shifting time is reduced and shifting speed is improved. The invention further relates to an electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicle transmission, in particular to a transmission and an electric vehicle. Background technique [0002] With the development of science and technology, environmental protection and energy conservation have become topics of increasing concern, and because of the characteristics of electric vehicles that can effectively solve environmental and energy problems, countries around the world have begun to focus on research on electric vehicles. [0003] The main performance indicators of electric vehicles are characterized by maximum speed, acceleration capability, climbing ability and cruising range, etc. The level of these indicators is directly related to its power transmission system. Most of the existing electric vehicle transmission systems are designed based on the mechanical automatic transmission of the internal combustion engine vehicle, and the clutch is retained. However, the structure ...
