The electric parking mechanism is studied for an electrically controlled two-speed auto transmission that is being developed for electric vehicles. Safety requirements include low-speed safe parking, reliable self-lock and the avoidance of abnormal parking. A dynamic model of the parking mechanism is established and analyzed using Adams software. Finally, failure of the parking mechanism due to wear...
Two-speed automatic transmission is one solution to increase the economic efficiency and dynamic performance of battery electric vehicles (BEV). Hydraulic control unit (HCU) is a key component in automatic transmissions, which determines the quality of shifting directly. Based on the structural scheme and shift logic of a two-speed dedicated electric vehicles transmission (2DET) with two wet clutches,...
