Pump arrangement

摘要

The driveshafts (6,5) of the two pumps (1,2) are driven by the common drive independently of one another. The pump (1) with the largest pump volume is arranged closest to the drive, and is driven by the hollow shaft. The hollow shaft has an intended breakpoint (4). The pump arrangement is installed in a road vehicle and the first pump (1) is a fan pump and the second is a steering aid pump (2). The second pump is furthest away from the drive, with its drive shaft (6) passing through the hollow shaft (5). The shaft of the second pump is connected via a gearwheel (3) with the drive. The intended breakpoint is formed by an all-round breakpoint.
