Abstract
Official abstract text for this publication.
The invention relates to a hydraulic device for a rail vehicle including a tank region for a hydraulic fluid, a motor having a pump for pumping the hydraulic fluid, a hydraulic connection panel for providing hydraulic fluid paths and for holding hydraulic components, a control region for controlling the hydraulic components, and a housing. The tank region and the control region are arranged on opposite sides of the hydraulic connection panel. The motor is arranged together with the pump on one side of the hydraulic connection panel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hydraulic device for a rail vehicle comprising: a tank region for a hydraulic fluid, a motor with a pump for pumping the hydraulic fluid, a hydraulic connection panel for providing hydraulic fluid paths and for holding hydraulic components, and a control region comprising a connector unit and an electrical interconnection, wherein the tank region and the control region comprising the connector unit and the electrical interconnection are arranged on opposite sides of the hydraulic connection panel, wherein the motor is arranged together with the pump on one side of the hydraulic connection panel, wherein the pump is arranged together with the motor in the tank region, the hydraulic device further comprising a holding structure that directly connects to each of the motor and the pump, the holding structure held in the tank region and coupled to the hydraulic connection panel, and wherein the motor and the pump are held independently of the hydraulic connection panel by the holding structure, wherein the tank region comprises a tank for storage of the hydraulic fluid and the pump is accommodated with the motor in the tank. 2. The hydraulic device of claim 1 , wherein the hydraulic components comprise at least one valve and/or at least one sensor, which are electrically controllable. 3. The hydraulic device of claim 1 , wherein the pump and the motor comprise a common shaft or two shafts coupled together, wherein the common rotation shaft or two shafts is/are separated from the hydraulic connection panel. 4. The hydraulic device of claim 1 , wherein the holding structure is coupled to the hydraulic connection panel. 5. The hydraulic device of claim 1 , wherein the tank region comprises a housing and the control region comprises a cover and the holding structure is fastened to the housing. 6. A hydraulic device for a rail vehicle, the hydraulic device comprising: a tank region for a hydraulic fluid, a hydraulic connection panel for providing hydraulic fluid paths and for holding hydraulic components, and a control region comprising a connector unit and an electrical interconnection, wherein the device comprises: a pump for pumping the hydraulic fluid, which is situated in the tank region, and is fastenable in the tank region to fasten a motor on the same side of the connection panel as the tank region for operating the pump on an outer surface of the tank region, the device further comprising a holding structure that directly connects to each of the motor and the pump, the holding structure held in the tank region and coupled to the hydraulic connection panel, and wherein the motor and the pump are held independently of the hydraulic connection panel by the holding structure, wherein the tank region comprises a tank for storage of the hydraulic fluid and the pump is accommodated with the motor in the tank. 7. A rail vehicle with a hydraulic device that includes a tank region for a hydraulic fluid, a motor with a pump for pumping the hydraulic fluid, a hydraulic connection panel for providing hydraulic fluid paths and for holding hydraulic components, and a control region comprising a connector unit and an electrical interconnection, wherein the tank region and the control region comprising the connector unit and the electrical interconnection are arranged on opposite sides of the hydraulic connection panel, and wherein the motor is arranged together with the pump on one side of the hydraulic connection panel opposite the control region, a holding structure that directly connects to each of the motor and the pump, the holding structure held in the tank region and coupled to the hydraulic connection panel, and wherein the motor and the pump are held independently of the hydraulic connection panel by the holding structure, wherein the tank region comprises a tank for storage of the hydraulic fluid and the pump is accommodated with the motor in the tank.
