Abstract

The invention provides an automatic transmission execution system of an automobile. The automatic transmission execution system comprises a transmission box. An automatic transmission box gear selecting and shifting execution mechanism is arranged at the top of the transmission box, a clutch is arranged on the front portion of the transmission box, a clutch execution mechanism and a TCU are arranged on the lateral face of the transmission box, and a manual-automatic integrated gear shifting controller is arranged in a cab. The clutch execution mechanism is a pneumatic assistance electric clutch execution mechanism, the manual-automatic integrated gear shifting controller comprises a shell, a gear shifting rod performs electronic control over triggering of a Hall element control switch, the TCU comprises a master control MCU, and a Freescale 32 high performance processor MPC5633M serves as the master control MCU. According to the automatic transmission execution system, the clutch execution mechanism, the TCU and the manual-automatic integrated gear shifting controller are organically combined, and technical supports are provided for achieving manual-automatic integration of middle-sized trucks, passenger cars, special cars and the like.

Description

technical field [0001] The invention relates to an automatic transmission system of a medium-sized truck, in particular to an automatic transmission execution system of an automobile. Background technique [0002] In order to solve the problem of complex structure and large space layout of the ATM automatic transmission gear selection and shift actuator, the 201120192775.5 ATM automatic transmission gear selection and shift actuator has been proposed. It mainly adopts the method of cross-shaped translation to realize gear selection and avoids the application of connecting rod structure, so that the structure of the whole actuator is simple, easy to arrange, small in size, easy to arrange, and realizes a new (cross-shaped translation method) ) to select the shift mode. The function of the elastic positioning pin device is to ensure that the neutral position does not drift and the positioning is reliable when the ATM automatic transmission gear selection and shifting actuator...
