Pneumatic gear-shifting control device of automatic transmission

Abstract

The invention discloses a pneumatic gear-shifting control device of an automatic transmission. The pneumatic gear-shifting control device of the automatic transmission is characterized by at least comprising a gear shifting cylinder and a position selecting cylinder. The gear shifting cylinder and the position selecting cylinder are installed on a first support and a second support in an orthogonal mode in the space, and the first support and the second support are arranged on one side of a gearbox. One end of the gear shifting cylinder is fixedly connected with the first support, and a gear selecting head which is used for selecting the position is arranged at the other end of the gear shifting cylinder. One end of the position selecting cylinder is fixedly connected with the second support, and a switching head which is used for shifting gears is arranged at the other end of the position selecting cylinder. The gear shifting cylinder and the position selecting cylinder communicate with a pneumatic control system. The pneumatic gear-shifting control device of the automatic transmission mainly has the beneficial effects that the structure is simple, the design is exquisite, the control over gear selection and gear shifting can be achieved in the mode that the gear shifting cylinder, the position selecting cylinder and the pneumatic control system are added under the condition that a transmission body is unchanged, and operation is easy, convenient and fast. Meanwhile, an operator only needs to correspondingly adjust the gear shifting cylinder, the position selecting cylinder and the pneumatic control system so that the control over different gears can be achieved, and the pneumatic gear-shifting control device of the automatic transmission has the high applicability.

Description

technical field [0001] The invention relates to the technical field of transmission devices, in particular to a pneumatic shift control device for an automatic transmission. Background technique [0002] With the development of automobile technology, automatic transmissions have been widely used in various types of automobiles. Mechanical automatic transmissions are widely used due to their simple structure, high transmission efficiency, and good reliability. [0003] In vehicles with rear-mounted gearboxes, vehicles with manual shifting mostly use a connecting rod or cable mechanism to complete the shifting. Due to the long transmission distance, a large operating force is required, and accurate coordination of hands and feet is required to complete the shifting operation. Mistakes will cause damage to the gearbox and serious traffic accidents. With the rapid development of electronic technology and the in-depth study of shifting theory, the way of car shifting has gradual...
