Abstract

The invention discloses a double-clutch hydraulic control device. The switch between double clutches is finished through hydraulically controlling the open / close of double clutches. By means of the scheme, the double-clutch hydraulic control device is simple in structure, excellent in performance, capable of realizing high-speed and high-precision gear shifting through matching with double electric clutches, short in gear shifting time, comfortable in riding, safe and environmental friendly.

Description

technical field [0001] The invention relates to a clutch technology, in particular to a clutch control technology. Background technique [0002] As a whole, the technology of automobile transmission system is developing from manual shifting to automatic shifting, especially the rapid development of computer technology is applied to the shifting transmission system at this stage, which makes the automatic transmission technology of automobiles develop rapidly. [0003] In recent years, there are three main types of automotive automatic transmissions: electromechanical automatic transmission (AMT), continuously variable automatic transmission (CVT) and hydraulic mechanical automatic transmission (AT). In the field of electronically controlled mechanical automatic transmissions, a new transmission mode has emerged in recent years, that is, dual clutch automatic transmission (Dual Clutch Transmission). Compactness, light weight, high transmission efficiency, low manufacturing c...
