Abstract

The invention provides a gear shifting device and a vehicle, belonging to the technical field of automobiles. The device includes a ring gear, a planet carrier, a planet gear, a first shifting component, a second shifting component and a first elastic element. A first disk is provided on one side of the ring gear, a second disk is provided on the first end of the second fixed part of the planet carrier, a third disk is provided on the first end of the first shift component, and the second shift member is provided with a third disk on one side of the ring gear. The first end of the gear member is movably connected to the second end of the first gear shift member, the second end of the second gear shift member is provided with a hydraulic element, and the first elastic element is located on the shoulder of the first gear shift member and the second gear shift member. between the end faces of the first end of the blocking member. The entire shifting process does not require the use of independently operating components such as oil pumps and air compressors, so that the entire device occupies less space. The entire shifting process does not require multi-stage conversion to achieve the shifting operation, and the device has good responsiveness. .

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a shifting device and a vehicle. Background technique [0002] The powertrain of a new energy vehicle mainly includes a motor and a reducer. The reducer mainly adopts a gearless form, a single-speed form and a two-speed form. Among them, since the two-speed reducer needs to meet the driving conditions of different working conditions, it is necessary to Add a shifter after the reducer. [0003] At present, shifting devices mainly include electronically controlled electrohydraulic, electropneumatic and electronically controlled electric. Among them, the electronically controlled electro-hydraulic shifting device and the electropneumatic shifting device are controlled by the electronic control unit to complete the shifting work of the reducer. [0004] However, the solenoid valve included in the electro-hydraulic shifting device must be used in conjunction with the oil pump an...
