Abstract

The invention discloses a gear cylinder for selecting gear of automobiles. The gear cylinder includes a cylinder body (6) and a piston rod (4) with one end inside the cylinder body (6) and conducting axial movement, and a gear piece matched with the piston rod (4) to realize gear selection. The gear piece includes a first gear slider (2), which is arranged at the end part of the piston rod (4) inside the cylinder body (6), and the piston rod (4) penetrates through the first gear slider (2) and it is connected with the first gear slider (2) in a sliding way; the precision of gear location of the gear cylinder is relatively high, so that the gear cylinder can be applied to the field of automobiles having a high gear selection precision requirement, reduces the volume of a gear device of an existing automobile, and meets the design requirements of the whole automobile; and the gear cylinder can also reduce the impact on the gearbox, thus improving the automobile's dynamic property and economical efficiency. In addition, the invention further discloses a pneumatic gear actuator.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a gear selection cylinder. In addition, the present invention also relates to a pneumatic gear selection actuator comprising the above gear selection cylinder. Background technique [0002] The research and development of the actuator is one of the key contents in the Automated Mechanical Transmission (AMT) system. The performance of the gear selection actuator directly affects the performance of the entire AMT system, and its response speed must be guaranteed Fast, accurate positioning, stable and reliable work. [0003] Pneumatic actuators have the characteristics of economical use and environmental protection, and commercial vehicles generally have ready-made air storage tanks, and the pneumatic energy can be directly provided by the air storage tanks without additional energy devices such as motors and oil pumps, so they are widely used In the AMT system. [0004] The pne...
