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.
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 structure associated with the mounting to support the brake shoes and brake shoe actuating mechanism which automatically adjusts the brakes for optimum operation.
Abstract:
An improved planetary gear drive, employing multiple countershafts to reduce the loads carried by the individual components, is disclosed wherein at least one helical gear set having sets of oppositely inclined oblique teeth is mounted for axial movement on a common shaft to transmit power from a drive component to a power component. A compression spring, disposed contiguous with one face of the helical gear set, cooperates with the oppositely inclined teeth of the helical gear set to resiliently move the helical gear set axially along its shaft to equalize the axial force components on its oppositely skewed sets of teeth. The invention may be embodied at any one of several different points in the gear train.
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 rings are disposed in the gap between the brake shoes and hydraulically actuated members are associated with the actuating rings to move them against the brake shoes and press the brake shoes against the braking surface. The hydraulic actuating members may be L-shaped slidable members which enclose the sealed annular space into which hydraulic fluid is introduced into the groove, a pair of hydraulic cylinders having pistons which move actuating rings associated with the brake shoes or a ring cylinder and ring piston assembly.
