Abstract:
A transmission with a hydraulic control system for a controlled pressurization of actuating members that are arranged on at least one rotary shaft, said hydraulic control system comprising a hydraulic control device with at least two control device plates, an intermediate layer between the control device plates, and at least one hydraulic connection between the hydraulic control device and the rotary shaft, said hydraulic connection comprising:an inner tubular element, an outer tubular element, and a tubular passage channel between the tubular elements, said tubular elements and passage channel being coaxial and each of the tubular elements having a first axial end portion and a second axial end portion, receiving portions of the shaft, and a stepped bore hole in one of the control device plates, wherein the first axial end portions are seated in the receiving portions of the shaft, the second axial end portions are received in the stepped bore hole, and the intermediate layer serves as axial constraint of one of the tubular elements, and wherein one of the control device plates comprises a fluid channel radially off-centered from the stepped bore hole, a connecting bore hole that is not parallel to the stepped bore hole, and an intermediate space of the stepped bore hole between the tubular elements, wherein the tubular passage channel receives a flow of fluid from the radially off-centered channel through the connecting bore hole and the intermediate space.
