Embodiment Construction

[0021] exist Figures 1 to 3 In , a hydraulic control device 1 for a parallel transmission of a motor vehicle is shown in different sections and positions. The hydraulic control apparatus 1 includes a control board arrangement 10 having a first control board 11 and a second control board 12 . An intermediate board 13 is arranged between the two control boards 11 and 12 .

[0022] A hydraulic transmission device 14 is integrated into the control board device 10 , and the hydraulic transmission device 14 includes a first hydraulic pump 15 and a second hydraulic pump 16 . Both hydraulic pumps 15 , 16 are driven by a single electric motor 18 .

[0023] The motor 18 is mounted on the side of the first control board 11 facing away from the second control board 12 . On the side of the second control panel 12 facing away from the first control panel 11 , the receiving space for the hydraulic transmission device 14 is closed hydraulically tight in the two control panels 11 , 12 by m...

Abstract

The invention relates to a hydraulic control comprising a control plate assembly and a hydraulic transport device for transporting a hydraulic medium. The invention is characterised in that said hydraulic transport device is integrated into the control plate assembly.

Description

technical field [0001] The invention relates to a hydraulic control device with a control panel arrangement and a hydraulic transmission device for the transmission of a hydraulic medium. Background technique [0002] In automatic transmissions, such as stepped automatic transmissions, CVT transmissions or dual clutch transmissions, there are hydraulic control devices, namely actuator control devices, such as clutch actuator control devices or switch actuator control devices, and cooling oil supply / lubrication Oil supply requires oil supply equipment (mostly pumps with a pump start mechanism). The pump priming structure is mostly a mechanical pump priming structure coupled to an internal combustion engine. [0003] In modern transmissions, this mechanical pump starter structure can complement the electric pump assembly (ie, electric motor and pump). [0004] Oil supply arrangements are known, no mechanical power pumps are adequately maintained for the transmission and clut...
