Automatic shift control system used for positively independent mechanical dual-flow transmission system

Abstract

The invention provides an automatic shift control system used for a positively independent mechanical dual-flow transmission system, which lays a foundation for realizing automatic shift manipulation of the transmission system. A driving system consists of four parts which adopt hydraulic driving modes and comprise an integrated gear selection shift driving system, a main clutch driving system, asteering clutch / brake control system and an engine throttle auxiliary control system respectively, thus replacing a gear selection shift handle, a main clutch pedal and a accelerator pedal of a manual shift control system respectively, wherein the integrated gear selection shift driving system, the main clutch driving system and the engine throttle auxiliary control system are parts in a common AMT; and the steering clutch / brake control system is not contained in the common AMT. The automatic shift control system achieves the aim of improving the shift quality according to the characteristicsof the positively independent mechanical dual-flow transmission system.

Description

technical field [0001] The invention relates to the field of automatic control of a crawler vehicle transmission system, in particular to an automatic shift control system for a positive independent mechanical double-flow transmission system. Background technique [0002] In the prior art, the positive independent mechanical double-flow transmission system adopts a manual mode for shifting operation, and the life of the main clutch is too short, the shifting is difficult, and the shifting quality is poor. And the existing manual gear shifting operation method requires high technical level of the driver, and the operation performance is not good. Contents of the invention [0003] Aiming at the existing technical defects, the present invention proposes an automatic shifting operation driving system, which replaces the manual shifting operation system. The tracked vehicle equipped with the mechanical dual-flow transmission system realizes the automatic shift operation, prot...
