Problems solved by technology

The shift dial moves the C-shaped block of the transmission to shift gears. As the number of shifts increases and the wear of mechanical parts causes the transmission gap to increase, the information on the shift position changes greatly, and even exceeds the pre-designed threshold of the system, resulting in Program misjudgment, selection and shift function invalid
Moreover, this gear selection and shifting mechanism needs to select a gear first and then shift gears every time it shifts gears, which is difficult to control, and if the gear selection transmission process fails, the gears cannot be shifted, and the entire mechanism is also ineffective.

Abstract

The invention provides an AMT automatic gear shifting device. The gear selecting process is omitted through the AMT automatic gear shifting device, and an original gear selecting and shifting mechanism is optimized into several independent gear shifting mechanisms. The AMT automatic gear shifting device comprises gear shifting motors and a shifting fork shaft, the output end of each gear shifting motor is connected with a worm structure, a worm gear structure is connected to one side of each worm structure in a meshed manner, and a main shaft of each worm gear structure is a gear shifting gear wheel shaft; each gear shifting gear wheel shaft comprises a gear shifting gear wheel, the shifting fork shaft is particularly a shifting fork shaft with a rack, the input end of the shifting fork shaft is provided with the rack parallel to the length direction of the shifting fork shaft, and the part of the rack is connected with the gear shifting gear wheels in a meshed manner; the output end of the shifting fork shaft is sleeved with a shifting fork structure, the shifting fork shaft moves in the gear shifting direction, and a sliding sleeve is externally connected to the shifting fork structure; the sliding sleeve comprises a sliding sleeve body with a synchronizer and a sliding sleeve body without a synchronizer; each gear shifting motor has N driving strokes, wherein the N is a natural number larger than or equal to 1, different strokes correspond to different feeding degrees of the shifting fork shaft, and one gear shifting motor correspondingly controls N gears.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission structure, in particular to an AMT automatic shifting device. Background technique [0002] At present, most of the shift mechanisms of electromechanical automatic transmissions (AMT) are hydraulic and pneumatic, and the gear selection and shifting actions are realized by controlling solenoid valves. Its disadvantages are complex structure, high cost, and power loss in the action process. The existing electro-mechanical AMT shifting mechanism includes two parts of gear selection and gear shifting, which are driven by respective motors, and the power of the motor is transmitted to the direction of gear selection and shifting through a deceleration and torque increasing mechanism. The shift dial moves the C-shaped block of the transmission to shift gears. As the number of shifts increases and the wear of mechanical parts causes the transmission gap to increase, the information on the s...
