Problems solved by technology
[0002] At present, most of the shift mechanisms of electromechanical automatic transmission (AMT) are hydraulic and pneumatic, and the gear selection and shifting actions are realized by controlling the solenoid valve. The disadvantages are complex structure, high cost, and power in the action process loss
Existing electronically controlled mechanical type AMT shifting mechanism, its structure sees figure 1 , which are several independent shifting mechanisms, and each motor controls the corresponding rack fork shaft respectively. The volume of the shifting mechanism is large, which causes the follow-up design to remain unchanged

The invention provides an AMT automatic gear selecting and shifting device. A gear selecting motor is used for adjusting the position of a gear selecting and shifting shaft to select gears firstly, and then a gear shifting motor is used for driving the gear selecting and shifting shaft so that rack-shifting-fork shafts can be driven to rapidly and accurate shift gears. The whole structure can control rapid gear shifting of the multiple rack-shifting-fork shafts by just arranging the two motors and is small in size, and subsequent product arrangement and design are facilitated. The AMT automatic gear selecting and shifting device comprises the gear selecting motor, the gear shifting motor and the gear selecting and shifting shaft. The gear selecting and shifting shaft comprises an annular gear part, a middle gear part and a gear shifting guide shaft part. The gear shifting guide shaft part is sleeved with a first bevel gear. The first bevel gear can move axially along a gear shifting guide shaft. A gear selecting worm is fixedly mounted at the output end of the gear selecting motor. The gear selecting worm is connected with a worm wheel part of a gear selecting gear shaft in an engaged mode. An output gear of the gear selecting gear shaft is connected with the annular gear part of the gear selecting and shifting shaft in an engaged mode. At least two rack-shifting-fork shafts are arranged relatively under the middle gear part in parallel.
Description
technical field [0001] The invention relates to the technical field of a vehicle transmission structure, in particular to an AMT automatic gear selection device. Background technique [0002] At present, most of the shift mechanisms of electromechanical automatic transmission (AMT) are hydraulic and pneumatic, and the gear selection and shifting actions are realized by controlling the solenoid valve. The disadvantages are complex structure, high cost, and power in the action process loss. Existing electronically controlled mechanical type AMT shifting mechanism, its structure sees figure 1 , which are several independent shifting mechanisms, and each motor controls the corresponding rack fork shaft respectively. The volume of the gear shifting mechanism is large, causing the follow-up design to remain unchanged. Contents of the invention [0003] In view of the above problems, the present invention provides an AMT automatic gear selection device, which first adjusts the...
