Abstract:
A brake disk assembly for a motorcycle wheel has a radially extending carrier integral with the hub and supporting a brake actuating member. The brake actuating member presses the friction lining of a brake disk against a brake ring on the wheel. In one embodiment of the invention only one brake actuating member is used and the two brake rings on opposite sides of the wheel are connected by a rod-like member. When the brake disk on one side of the wheel is actuated by pressing one brake disk against its brake ring, the latter brake ring presses the opposite brake ring through the connecting rod against the second brake disk. The actuating members may be either mechanical or hydraulic.
Abstract:
To increase the life of brake linings especially for heavy-duty vehicles and to increase reliability, an operating brake which is directly actuated by compressed air and a blocking brake which is spring actuated and has a compressed air spring relief, both in full lining configuration, are provided in a housing having radial ribs and in heat conduction with the two brake units to convectively dissipate the heat to ambient air. The blocking brake is actuated for emergency downhill or like braking situations to contribute to the dynamic braking torque.
Abstract:
An autoignition two-stroke internal combustion engine utilizes rectangular working chambers and pistons with bar-type seals and rotary sleeve valves which connect the working chambers to exhaust gas turbines for secondary expansion and a supercharger. The supercharger is thermally decoupled from the expansion turbines but the expansion turbines are connected to the supercharger and the crankshaft by a planetary gear transmission which can be cut in or out by a disk-type brake or clutch.
Abstract:
A fully lined disk brake has a brake housing rotatably mounted on a wheel and segmented arcuate shaped brake shoes supported in the brake housing by a fixed mounting on the wheel assembly which extends over the radially outward open end of the housing to support the brake shoes and is movable from over the open end of the housing to permit access thereto for replacing the brake shoes without dismantling the brake actuating mechanism. The invention provides brake shoes having a device for association with the mounting to support the brake shoes and brake shoe actuating mechanism which automatically adjusts the brakes for optimum operation.
Abstract:
A fully coated disk brake with a brake housing carrier fastened to the wheel or its hub and revolving therewith. A brake housing is seated on the carrier and opens radially towards the outside. The housing accommodates brake rings, carrying a friction coat, fixedly in the peripheral direction, but axially displaceable, and capable of being pressed together by a tightening device for the purpose of braking. The brake housing carrier has distributed over its periphery carrier arms which extend in the axial direction. These carrier arms mount the brake rings and at their ends have abutments which restrict the axial movement of the brake rings. Between the brake rings are radially outward running air passage channels for the flow of cooling air between the carrier arms into the brake housing. The wheel hub may be constructed to serve as brake housing carrier. The brake housing rings may be axially displaceable on the carrier arms of the brake housing carrier and are secured against rotation by projections forming part of the carrier arms; the brake disks, seated between the brake housing rings, are secured by projections forming part of the brake carrier arms.
Abstract:
A combustion chamber assembly for a two-stroke internal combustion engine has, in the upper dead point position of the piston, a space defined between the piston bottom and the cylinder head which is of the shape of a frustum of a right-circular cone or the shape of a right-circular cylinder. Surfaces of the piston bottom and the cylinder head extend tangentially to the wall of the space at 180.degree. offset from one another and are juxtaposed with surfaces of the cylinder head and piston bottom, respectively, defining narrow gaps squeezing fluid flow into this space tangentially form opposite directions to induce a vortex in the space in a single sense. The fuel injector opens axially into this space for autogenous ignition or self-firing or a spark plug extends axially into this space for external ignition.
Abstract:
A hydraulically actuated fully lined disc brake assembly for braking a wheel of a motor vehicle has a brake housing which is provided with a gap which is open on its radially exterior side. Brake discs which fully line the brake housing are disposed in the gap and are supported on a removable bracket which is fixed against rotation. The brake discs are fixed against rotation with the wheel but are free to move axially. A hydraulic actuating mechanism is disposed in the gap between the brake discs and is designed to apply pressure against the discs at their radial center point to actuate the brake discs at their most efficient radii. The brake housing is supported on the wheel and can be removed for replacement of the brake discs after the wheel has been removed without disassembly of the brake actuating mechanism.
Abstract:
A brake assembly having a brake housing which has an annular member enclosing an annular gap of channel-like cross-section open at its radially exterior side is provided with at least one pair of segmental brake shoes. Annular actuating and thrust rings are disposed in the gap between the brake shoes and hydraulically actuated members are associated with the rings to move them against the brake shoes and press the brake shoes against the braking surface. The hydraulic actuating members may be a pair of hydraulic cylinders having pistons which move actuating rings associated with the brake shoes or a single piston acting against a projection from one actuating ring.
Abstract:
In a vehicle having driven and non-driven wheels and driven and non-driven shafts a brake system including wheel brakes and auxiliary drive line brakes. The auxiliary drive line brakes are designed with a heat absorbing capacity to absorb at least twice the maximum heat energy as the wheel brakes. The auxiliary drive line brakes are watercooled friction disc brakes operating without self-intensification and comprising dry friction elements. The brake system further comprises actuating means including a singular application means and separate brake circuit means for the drive line brakes and the wheel brakes. The actuating means forces the system to operate the auxiliary drive line brakes alone in a first mode of operation during which the wheel brakes remain unbraked and to then operate the system in a subsequent second mode of operation in which the wheel brakes are operated in addition to the drive line brakes such that the total applied braking moment is distributed to each wheel approximately in proportion to the dynamic load on that wheel.
