TESTBENCH DEVICE, IN PARTICULAR TRIBOMETER, FOR PISTON RING / CYLINDER RUNWAY SYSTEMS

摘要

A testbench device for the analysis and/or optimisation of tribological properties in a piston ring/cylinder runway system, includes a cylinder segment-holding device for holding a cylinder runway segment as a testpiece, and a piston ring-holding device holding at least one piston ring element and capable of bringing the at least one piston ring element into bearing contact with the cylinder runway segment. An actuation device actuates the cylinder runway segment and/or the piston ring element such that relative displacement with respect to one another takes place in at least one defined direction of space, in particular in the form of an oscillating movement. The piston ring-holding device has a piston having a ring-shaped outer contour and with at least one circumferentially continuous piston ring groove, in which a piston ring is held as a piston ring element.

1. A testbench device for the analysis and/or optimisation of the tribological properties in a piston ring/cylinder runway system, comprising:
a cylinder segment-holding device configured to hold a cylinder runway segment as a testpiece; a piston ring-holding device having a piston with a ring-shaped outer contour and with at least one circumferentially continuous piston ring groove; a piston ring element held on the piston ring-holding device and capable of being brought into bearing contact with the cylinder runway segment, wherein the piston ring element is a piston ring arranged in the circumferentially continuous piston ring groove; and an actuation device configured to actuate at least one of the cylinder runway segment and the piston ring element such that the cylinder runway segment is displaced relative to the piston ring element in at least one defined direction of space.
