Abstract

The invention relates to a multistage gear-shifting execution cylinder which comprises a piston rod, a front end cover, a cylinder body, a front balancing piston, a limit spacer bush, a main piston, a rear balancing piston and a rear end cover. The front end cover, the front balancing piston and the limit spacer bush are arranged in a left cavity of the cylinder body and sleeved on the piston rod 1, and the piston rod is integrally connected with the main piston through a nut mechanism. The rear balancing piston and the rear end cover are arranged in a right cavity of the cylinder body. Air inlets are formed above the left cavity and the right cavity of the cylinder body. The multistage gear-shifting execution cylinder adopts a multi-cavity dynamic balancing principle, and utilizes sectional area difference of the cavities to achieve internal balance of the piston and control output stroke of the piston rod.

Description

technical field [0001] The invention relates to the field of hydropneumatics, in particular to an execution unit of an air-controlled shift assembly, which completes the shift action instructed by the control valve according to the driver's manipulation intention. Background technique [0002] At present, the shifting of domestic construction machinery, especially loaders, mainly includes two states, one is the mechanical shifting operation using a flexible shaft for transmission; the other is an electronically controlled full-power gearbox represented by ZF, two states The function of the gearbox on the loader is to change the direction and speed of the loader. It's just that there is a difference in the way of manipulation, but the price gap is huge. [0003] Mechanical flexible shaft control has become the mainstream configuration of domestic gearboxes because of its low price and easy maintenance. However, flexible shaft manipulation has a large manipulation empty stro...
