Abstract
A roller is disclosed which is intended to have frictional engagement with a vehicle wheel during a testing operation and which is constructed by welding together: a central supporting shaft, a plurality of outwardly-extending axially-spaced supporting discs, and a plurality of axially-extending members supported in slots on the peripheries of the discs and arranged to provide wheel-engaging ribs extending at right angles to the direction of motion of the wheel periphery.

A roller adapted to engage and drive a wheel for testing purposes, comprising:
- a shaft extending along the axis of rotation of the roller at least part of the roller's axial length,
- a plurality of generally disc-shaped supporting members secured to the shaft at axially spaced points and extending generally radially outward from the shaft,
- said disc-shaped supporting members each having a plurality of circumferentially-spaced slots formed in its periphery and axially aligned with corresponding slots in the other supporting member or members, and
- a plurality of axially extending wheel-engageable members secured to the disc-shaped members and supported in the slots formed therein, each said wheel engageable member having a substantially V-shaped cross-section, each side of which provides a wheel-engageable rib.
A roller adapted to engage and drive a wheel for testing purposes, comprising:
- a shaft extending along the axis of rotation of the roller at least part of the roller's axial length,
- a plurality of generally disc-shaped supporting members secured to the shaft at axially spaced points and extending generally radially outward from the shaft,
- said disc-shaped supporting members each having a plurality of circumferentially-shaped slots formed in its periphery and axially aligned with corresponding slots in the other supporting member or members, and
- a plurality of axially extending wheel-engageable members secured to the disc-shaped members and supported in the slots formed therein, each said wheel engageable member having a cross-sectional form which provides two parallel circumferentially-spaced wheel-engageable ribs.
A roller, adapted to engage and drive a wheel for brake testing purposes, comprising:
- a shaft extending along the axis of rotation of the roller at least part of the roller's axial length,
- a plurality of generally disc-shaped supporting members secured to the shaft at axially-spaced points and extending generally radially outward from the shaft, and
- a plurality of axially-extending wheel-engageable members each wheel engageable member secured to and supported by the disc-shaped members, and having a cross-section which provides two circumferentially-spaced wheel-engageable ribs.
In a brake tester, a roller for engaging and driving a wheel comprising:
- a plurality of physically distinct, unitary rib-bearing members, each rib bearing member providing two wheel engaging surfaces;
- and
- a plurality of support member means spaced apart from one another on a common axis each having slot means therein for mounting each of said rib-bearing members spaced apart from one another on the circumference of a cylinder such that the wheel engaging surfaces of each rib-bearing member are oriented in a wheel engaging position and such that each said rib-bearing member is individually replaceable.
