Hydraulic pump arrangement for use in transfer gearbox in motor vehicle, has bearing element has sub area provided in each bearing receiver for positioning drive unit opposite to pump unit

摘要

The arrangement has a bearing receiver (9) that is formed in a bearing section (6) of a drive unit (13), and another bearing receiver (17) that is formed in a bearing section (25) of a pump unit (14) e.g. rotary piston pump. The drive unit encloses a drive shaft (4) that is rotatably mounted over a bearing element (8) e.g. radial ball bearing (7). The pump unit has a rotor (19) effectively connected with the drive shaft. The bearing element has a sub area (10) provided in each bearing receiver for positioning the drive unit opposite to the pump unit. An independent claim is also included for a transfer gearbox comprising an input shaft.
