Mechanical gear shifting double-speed-change control mechanism

Abstract

The invention provides a mechanical gear shifting double-speed-change control mechanism, and relates to the technical field of automobile control equipment. The mechanical gear shifting double-speed-change control mechanism aims at solving the problems that when a conventional mechanical gear shifting double-speed-change control mechanism is in actual use, due to the fact that a gear shifting ballhead and a gear selecting ball sleeve are continuously rubbed, the surfaces of the gear shifting ball head and the gear selecting ball sleeve are prone to being abraded, the service life of components is shortened, the automatic reset effect of a gear selecting rod is not ideal enough, the gear shifting process is not smooth, and the use hand feeling is affected. The mechanical gear shifting double-speed-change control mechanism comprises a shell, wherein a bottom plate is arranged at the bottom end of the shell. According to the mechanical gear shifting double-speed-change control mechanism,due to the fact that the inner wall of the gear selecting ball sleeve is of an arc structure, a rolling shaft is arranged on the arc inner wall of the gear selecting ball sleeve, the gear selecting ball sleeve is rotationally connected with the gear shifting ball head through the rolling shaft, a sealing soft sleeve is arranged at the bottom end of the gear selecting ball sleeve, the sealing softsleeve is tightly attached to the gear selecting ball sleeve in a bonding manner, and when the gear selecting rod is shaken, friction between the gear shifting ball head and the gear selecting ball sleeve is reduced; and the sealing soft sleeve is arranged at the bottom end of the gear selecting ball sleeve, and lubricating oil can be prevented from leaking out from the bottom.

Description

technical field [0001] The invention belongs to the technical field of automobile control equipment, and more specifically relates to a mechanical shift double-speed control mechanism. Background technique [0002] The transmission control mechanism is used to change the collocation of transmission gears to achieve gear shifting. Under the driver's operation, the transmission control mechanism can quickly, accurately and reliably take off, engage in a certain gear or return to neutral. The manual shift control mechanism consists of a shift lever, a gear selector lever, a base and a zipper. The shift lever converts the force of the driver pushing the shift lever into the power of the zipper pulling the gearbox to shift gears through the well-known lever principle through the lever. [0003] For example, the invention of application number: CN201711173389.X is a mechanical single-lever gearbox gear selection and shifting control mechanism. The shifting flexible shaft is con...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a mechanical shifting dual-speed operating mechanism to solve the problem that when the conventional mechanical shifting dual-speed operating mechanism is actually used, the shifting operation is performed by shaking the gear selection lever. Due to the constant friction of the gear ball sleeve, the surface of the gear shift ball head and the gear selection ball sleeve is easy to wear, which reduces the service life of the components, and the bottom of the lubricating oil leaks out. It is not ideal enough, which leads to the problem that the shifting process is not smooth and affects the use feeling
