Hydraulic wheel set press

摘要

The invention relates to a hydraulic wheel set press for the simultaneous pressing of two wheel (1, 2) or brake disks on a wheel axis (3) having a frame construction (4) mounted on a base (5), said frame construction being comprised of two identical vertical press stands (6, 7) connected to one another in a fixed manner at a mutual distance via horizontal traverses (8, 9). The press stands (6, 7) each have a housing (10, 11) serving to accommodate a centering cylinder (12) engaging the wheel axis (3) on one end (14 15). In addition, a press cylinder (13) is provided concentrically to the centering cylinder (12). said press cylinder engaging the wheel (1, 2) or brake disk to be pressed, as well as control devices (22) for loading each of the two cylinders (12, 13) with a pressure medium. Measurement devices (20, 21) are provided on the base (5) that detect the lift of each of the cylinders (12, 13) and are connected to a control device (22) provided for regulating the loading of the cylinders (12, 13) with pressure medium as a function of the lift thereof.

主权项

1. A hydraulic wheel set press for simultaneously pressing two wheel or brake disks onto a wheel axle, the press comprising:
a frame mounted on a foundation, the frame comprising two spaced apart vertical press stands rigidly connected to one another by a horizontal traverse; a housing connected to each press stand; a centering cylinder disposed within each housing, the centering cylinder engaging the wheel axle on an end of the wheel axle; a press cylinder disposed within each housing and arranged concentrically to each centering cylinder, each press cylinder engaging a wheel or brake disk to be pressed onto the axle; at least one control device for loading the centering cylinders and the press cylinders with a pressure medium; at least one measurement device for detecting the lift of the centering cylinders and the press cylinders, the at least one measurement device connected to the at least one control device; wherein the at least one control device regulates the loading of the centering cylinders and the press cylinders with a pressure medium as a function of the lift detected by the at least one measurement device.
