摘要:
In a hydraulic control arrangement for an automated shift transmission, in particular a dual clutch transmission in a motor vehicle including a hydraulic control arrangement, the hydraulic control arrangement has a main pump and a controllable additional pump which jointly ensure that oil is supplied to the hydraulic control arrangement. The additional pump can feed into a control channel of a lubricating pressure slide and build up an adjustable lubricating fluid control pressure. The lubricating fluid pressure in the lubricating cooling system is adjusted in a simple and inexpensive manner by lubricating pressure slide changes modifying the lubricating control pressure in the lubricating cooling system.
