Novel gear-shifting speed-changing executing device and vehicle gearbox

Abstract

The invention provides a novel gear-shifting speed-changing executing device and a vehicle gearbox, and belongs to the technical field of automobile production. The novel gear-shifting speed-changingexecuting device comprises an end cover, a plurality of gear shifting cylinders and a plurality of shifting forks, the plurality of shifting forks are arranged below the end cover in a sliding mode, the plurality of gear shifting cylinders are fixedly arranged on the lower end surface of the end cover, are parallel in an axial direction, and are connected with the plurality of shifting forks in aone-to-one correspondence manner, and the gear shifting cylinders are used for driving the shifting forks to drive a change wheel to slide and shift gears. The vehicle gearbox adopts the novel gear-shifting speed-changing executing device, according to the novel gear-shifting speed-changing executing device, the starting point positions and the ending point positions of the strokes of the gear shifting cylinders are used as switching points of gears, the accuracy of executing the gear shifting operation is guaranteed, the plurality of gear shifting cylinders are arranged on the same one end cover, and a gear shifting executing mechanism of an overall structure is formed, so that the gear shifting executing mechanism is convenient to install, compared with a traditional gear-shifting speed-changing executing mechanism, technology is more advanced, the vehicle gearbox is more compact in structure and convenient to install, and the gear switching is accurate.

Description

Technical field [0001] The invention belongs to the technical field of automobile manufacturing, and more specifically, relates to a new type of shifting and speed changing actuator and a vehicle gearbox equipped with the new type of shifting and speed changing actuator. Background technique [0002] Automobiles are widely used in the production and life of modern people. Shift actuators are the actuators that realize automobile speed changes. Especially for the characteristics of high load and high speed of trucks, the momentum is huge during high-speed driving. Therefore, it is important to realize gear shifting. The actuator puts forward higher requirements. In order to ensure the accuracy and reliability of the gear shift when the car is shifting, the shift actuator of the truck mainly relies on the cylinder to realize the gear selection and lock function. Shift actuators often use shift selection cylinders and shift lock cylinders arranged perpendicular to each other to coop...
