Abstract: An actuating device for a parking brake with a shell-shaped handbrake lever essentially comprises a locking device that includes a detent segment with a detent pawl. The device is operated by an actuating rod. The handbrake lever is composed of half-shells enclosed by a cover strip with bearing bushings for the locking device as well as for pivotable mounting in a pedestal bearing that is mounted on the body. The connected half-shells are each provided with molded tubular guide projections for the actuating rod. The latter is connected with a one-piece handle that slips over it, producing, together with the cover strip and the half-shells, a flat continuous outer surface for the handbrake lever.

Abstract: A handle has an inner hub member which engages a shaft and rotates about a longitudinal axis therewith, an outer hub member which is disposed around the inner hub member and is coaxial therewith, and resilient material disposed in a space between the inner and outer hub members. The resilient material effects the transfer of rotational movement between the inner and outer hub members, and under normal operating conditions, the outer hub member is generally coaxial with the inner hub member and rotates in a tangential direction to effect the rotation of the inner hub member and the shaft. Thus, upon the rotation or movement of the outer hub member in a direction other than the tangential direction which results in the outer hub member extending along an axis angled to the longitudinal axis of the inner hub member, the inner hub member maintains its direction along the longitudinal axis by virtue of the resilient material disposed between the inner and outer hub members.

Abstract: The damped flywheel comprises two coaxial masses (1, 2) which are mounted for rotation of one with respect to the other against a torsion damper device (3), with one of the masses comprising a central nose (4, 40) projecting axially and penetrating into a central aperture (5, 50, 51) of the other mass, With support member(s) (6) being interposed between the said nose and the said aperture. These member(s) (6) comprise at least one plain bearing (70, 62 to 66) in the form of a hard, semi-crystalline polyetheretherketone material such as ARLON, for the rotary mounting of the mass having the central aperture (5, 50, 51) on the mass having the central nose (4, 40).

Abstract: An improved end fitting for push-pull blade controls is formed of two tubes connected together by a swivel joint. One tube of the compound fitting is attachable to an end of the tubular sheath of the control and anchors the ends of ball races of the control. The other tube of the compound fitting houses a reciprocative end rod connectable to an end of the push-pull blade that extends fully through the tube attached to the sheath and through the swivel joint. A simple but effective swivel joint is formed by an outwardly flared end of one tube movably captured in an inwardly flared end of the other tube. Thus, while the tube attached to the sheath of the control is installed in a fixed position, the other tube with the end-rod is deflectable.

Abstract: A high-speed flywheel includes a composite rim supported for rotation about a central axis which is perpendicular to the plane of the rim. The rim includes at least a pair of rim portions or regions of differing elastic modulus in the circumferential direction of the material forming the rim. Moreover, a radially outer portion of the rim has a higher elastic modulus in the circumferential direction, while a radially inner portion of the rim has a lower elastic modulus in the circumferential direction. This variation of circumferential elastic modulus is achieved by a selected radial variation of the angle of the fiber reinforcement material relative to the circumferential direction of the rim. A result is that the radially inner portion of the rim transfers radial force to the outer portion, with a resulting lower radial stress in the radially inner portion of the flywheel rim. An improved speed of operation and greater energy storage for the flywheel is achieved.
