Abstract

The invention discloses an automatic transmission with a brushless wire-driven centrifugal ball arm jointing device for an electric automobile. The transmission comprises a brushless wire-driven ball arm jointing device. Shift control of the transmission is achieved by controlling power on and power off of an electromagnet of the brushless wire-driven centrifugal ball arm jointing device. The transmission disclosed by the invention has the advantages of being simple and compact in structure, capable of achieving wire-driven dynamic shifting, smooth to shift and the like.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle transmission, and relates to an electric vehicle automatic transmission, more precisely, an electric vehicle automatic transmission with a brushless wire-controlled centrifugal ball arm joint device. Background technique [0002] Automatic transmissions are widely used in various vehicles such as automobiles, electric vehicles, and construction machinery. The existing automatic transmissions mainly include hydromechanical automatic transmission (AT), metal belt continuously variable automatic transmission (CVT), mechanical automatic transmission (AMT) and dual clutch automatic transmission (DCT). The shifting process of the above four types of automatic transmissions is controlled by an electronically controlled hydraulic servo device. The hydraulic servo device is composed of a hydraulic pump, multiple hydraulic valves, multiple hydraulic clutches, multiple brakes, etc., with complex str...
