  • Patent number: 9243549
    Abstract: An actuating device includes an exhaust flap of a supercharging pressure control of turbocharged internal combustion engines. The exhaust flap is arranged pivotably in an exhaust pipe, in particular in the housing of a turbine of an exhaust-gas turbocharger, and controls in dependence on the compressor-side supercharging pressure the opening cross section of a bypass line which circumvents the turbine. The exhaust flap is arranged on an actuator arm which is fastened on a shaft mounted rotatably in the exhaust pipe and adjustable from outside the exhaust pipe via an adjustment lever and a control rod which is articulated thereto and via a linear control motor. In order to avoid vibration-induced buzzing noise in the actuating device, a friction damper is connected into the force flow between the shaft and the control rod, in particular for system damping in the region of the exhaust flap.

  • Patent number: 6351373
    Abstract: A hinge engages a cam such that the hinge first rotates relative to the cam, then linearly engages the cam. Preferably, the hinge includes a guiding post that rides along a raised arched surface on the cam during the rotary motion of the hinge. Linear motion between the hinge and the cam preferably begins when the guiding post rides off the end of the arched surface. The rotary motion of the hinge is constrained by one or more engagement assemblies. In a preferred embodiment, one or more cams are mounted on a receiving structure and one or more hinges are mounted in corresponding locations on a detaching structure, where said detaching structure is physically separable from the receiving structure. Engagement between the one or more cams and the one or more corresponding hinges allows the detaching structure to first rotate relative to, then linearly engage, the receiving structure, providing for reliable blind mating between connectors on the detaching structure and connectors on the receiving structure.

  • Patent number: 5197704
    Abstract: An angle adjusting device for a display device has a pair of fixed axes abutted on the both ends of a rotatable axis and a pair of coil spring wound over the abutted portions. The angle of inclination of the display device is arbitrarily controlled by a total frictional torque obtained between the inner walls of the coil springs and the rotatable and fixed axes.

  • Patent number: 5165762
    Abstract: A quick-release apparatus having improved features is used with a hub and axle assembly for attaching a bicycle wheel to the frame of the bicycle. The assembly includes a hollow hub for mounting a bicycle wheel and a hollow axle extending through the hub and rotatably mounting the hub. The axle has a pair of opposite ends which extend from opposite ends of the hub and are interfitted with lower tips of a pair of fork tines of the bicycle frame. A first improved feature is a protuberance on the body of a cam lever assembly serving as a locator which positively aligns the cam lever to pivotally move the cam lever to the proper engaged position and prevents the cam lever from being used as a wrench to rotate the drawbar shaft. The second improved feature is an adjustable nut assembly which can be easily preset to have the correct number of compression washers to impose the desired level of tensioning force on the drawbar shaft when the cam lever arm is moved to its engaged position.

  • Patent number: 5082387
    Abstract: A pivot joint for a rotary lever has a spacer extending axially from a foundation such as an engine motor component. The spacer includes a cylindrical ferrule. A rotary lever and a belleville spring, both having a bore of a size to fit over the outside of the ferrule in a sliding fit, are slid over the ferrule. The belleville spring has an uncompressed cone height to thickness ratio of 1.4 to 1.8 and is compressed by at least 50% of the uncompressed cone height. The joint also includes a means for fastening the spacer to the foundation and a means for securing the lever and belleville spring onto the ferrule. The securing means bears against the free end of the ferrule to compress the spring to provide a substantially uniform operating torque from one assembly to another.

  • Patent number: 5040915
    Abstract: A breakaway mount connects a tool such as a welding torch with a robot or other automated machine. The mount can fully separate and detach from a baseplate in the event of a collision between the tool and the workpiece. The pneumatically operated mount is reassembled with the baseplate in a two-step procedure which allows the operator to move his fingers and hands away from the apparatus to avoid injury when the components are fully assembled. The breakaway mount can include a wrist joint which swivels back and forth in response to a collision between the tool and the workpiece. The apparatus can also be affixed with sensors to detect partial or complete detachment between the mount and the baseplate. The sensors shut down the robot or other automatic machinery in the event of partial or complete detachment. A second series of sensors can also be added to detect the movement in the wrist joint to likewise shut down the machinery.

  • Patent number: 4934860
    Abstract: A support arrangement which allows pivoting of a non-rotatable shaft has a flexure structure and a pair of axially-displaced inner and outer hubs respectively connected to, and disposed inwardly and outwardly of, the flexure structure. The flexure structure is composed of a disk-shaped flexural elements disposed in stacked, axially spaced relation to one another and connected peripherally one to the next. The flexural elements together define a frictionless, laterally stiff, fulcrum or pivot point about which the shaft can pivot through a predefined range of angular motion. The inner hub is attached to an inner end one of the flexural elements at an interior peripheral edge thereof, whereas the outer hub is attached to an outer end one of the flexural elements at an exterior peripheral edge thereof. The shaft extends axially through the bores in the hubs and an opening in the flexure structure along a common axis, and is rigidly attached to the inner hub.

  • Patent number: 4917343
    Abstract: An adjustable support has two adjustable support members 6, 11. A spring 17 mounted on pin 8 biases members 6, 11 together so that the peripheral and bevel teeth 7, 405 and 16, 406 engage to lock the members 6, 11 together at a required position. When member 11 is to be moved relative to member 6, lateral movement of member 11 against the bias of spring 17 enables the teeth 7, 405, 16, 406 to be disengaged and member 11 to be rotated to the required position for the article support arm 3.

  • Patent number: 4898491
    Abstract: A pivot assembly including a rotating member, a mounting member for supporting the rotating member, and a pivotal interconnection for the members. The interconnection enables rotation about a pivot axis and inhibits translation of the rotating member relative to the mounting member along the pivot axis. There are also structure enabling tilting of the rotating member about a tilt axis transverse to the pivot axis, and gripping elements for inhibiting relative rotation about the pivot axis. The gripping elements increase grip between the adjacent sections when the rotating member is tilted about the tilt axis in a first direction, and decrease grip when the rotating member is tilted about the tilt axis in a second and opposite direction to enable rotation of the rotating member.
