Abstract:
Brake tester roller comprising replaceable lining layer and consisting of a rotating support (1) and two or more removable semi-cylindrical shells (2, 3), the outer surface of which is non-slip, secured on said roller by screws or any other equivalent means. The device of the invention is suitable for use in industrial applications involving equipment for mechanical workshops. It is intended to be fitted to brake testing systems for light, utility and heavy-goods vehicles.
Abstract:
Braking and coupling device with at least two pairs of symmetrical frusto-conical friction surfaces (1, 5), of which one pair forms a trapezoidal annular channel, said friction surfaces being self-locking on contact. The devices are suitable for any mechanism or machine requiring braking or coupling devices, but are primarily designed for use in road vehicles such as motorcycles, cars, lorries or coaches, or in other vehicles such as rolling stock or aircraft.
Abstract:
The disc brake is associated with flat and truncated surfaces. The combination of a brake with a disc containing two standard pads (10) is applied onto the flat friction surfaces disposed on each side of the disc (1). One or two pistons (6) act in one or two lateral cylinders (5) on an axis parallel to the axis of the rotating elements and mounted in a fixed stirrup (4). This stirrup is equipped with a peripheral cylinder (7) containing a moving piston (8). The piston is arranged to apply onto an oscillating lever (11) pivoting on the stirrup and carrying wear pads (12). The pads act on the truncated friction surfaces (3) forming the internal sides of a trapezoidal sectioned throat provided on the periphery of the disc (1).
