The transverse strut (3) consists of an extruded aluminum profile with an extrusion structure extending in the longitudinal direction of the transverse strut.Type: GrantFiled: November 21, 1995Date of Patent: September 1, 1998Assignee: VAW Aluminium AGInventors: Franz Steimmel, Walther Hasenpatt, Kai-Uwe Jentsch, Jorg Ebert, Dieter Bungarten, Olaf Elsner, Herbert Linden, Michael Hellenkamp, Gerhardt Sollner, Karl-Heinz von Zengen, Peter Harbig, Joachim Lowen

Patent number: 5566969Abstract: A motor vehicle rear axle suspension has an inherently stiff axle guide member. The axle guide member is articulated by a universal joint on the vehicle body in the central longitudinal plane of the vehicle. Lateral guidance is effected by a lateral guide linkage. In order to reduce the tendency of the rear axle to oversteer under the action of a lateral force, an axle tube has a configuration curved in the forward direction of travel and is articulated directly on the body by a universal joint.Type: GrantFiled: June 1, 1995Date of Patent: October 22, 1996Assignee: Mercedes-Benz AGInventor: Peter Tattermusch

Patent number: 5492353Abstract: A camera dolly has a steering compensator including offset shaft sections and drive members rotationally displaceable from each other. The steering compensator provides steering angle correction in conventional steering wherein the front wheels of the dolly remain fixed straight ahead and the rear wheels steer. A crab-conventional camera dolly steering shift mechanism uses shift plates and sprockets on a vertical axle to shift between crab and conventional steering modes. An electronic shifter, provided as an accessory, automatically shifts between crab and conventional steering modes. A rocker suspension for the wheels of the camera dolly reduces undesired movement of the dolly, and of a camera mounted on the dolly, when the dolly wheels encounter a bump or obstruction. A bogey wheel system improves the performance of the rocker suspension by offsetting the wheels of the dolly dual wheel sets.Type: GrantFiled: July 23, 1993Date of Patent: February 20, 1996Assignee: Leonard Studio Equipment, Inc.Inventor: Leonard T. Chapman

Patent number: 5429423Abstract: A non-driven tubular vehicle axle assembly in which the axle body is formed from the mating of opposing axle sections constructed of sheet material formed into channel members. The utilization of channel members of differing lengths combined in the construction of the axle body along with separately formed spring pads and knuckle/king pin mountings provides for ease of assembly of axles of various length and specification.Type: GrantFiled: January 7, 1994Date of Patent: July 4, 1995Assignee: Dana CorporationInventors: Paul Pollock, Dick Ryan, Dennis Mahoney

Patent number: 5411287Abstract: A torsion axle for a vehicle includes an elongated axle tube enclosing first stage torsion shafts and second stage torsion shafts all having a common axis, and a metal tube or a non-circular portion of the axle tube and a plurality of resilient rubber rods confine each of the shafts for torsionally resisting rotation of the shaft. Each first stage metal tube is secured to the surrounding axle tube, and each second stage metal tube is connected to the corresponding first stage shaft. A stud projects outwardly from each second stage metal tube through a slot within the surrounding axle tube to limit rotation of the second stage tube with the first stage shaft, and a crank arm and eccentric spindle are secured to the outer end portion of each second stage shaft for receiving a wheel. In modifications, the first stage shafts for both the left and right wheels are connected as one shaft, and a hydraulic winch cable and spool provide for pre-rotating the one shaft or the axle tube to lower and raise the vehicle.Type: GrantFiled: January 10, 1994Date of Patent: May 2, 1995Inventor: Curtiss W. Henschen

Patent number: 5411286Abstract: In this improved trailer chassis, the accessories which typically added weight without adding to the structural capacity of the trailer have been replaced with accessories which are incorporated into the structural members. The frame of the trailer chassis is comprised of a front and rear beam connecting two longitudinal side beams that incorporate a recess to capture the trailer floor decking. The axle beam mounts between the two side beams to serve as lateral support to the side beams and as a flooring beam and incorporates a open section into its section through which an axle can be mounted. The fenders for the trailer are mounted so that they contribute to the structural integrity of the frame while serving as a side enclosure in addition to a wheel well.Type: GrantFiled: March 16, 1993Date of Patent: May 2, 1995Inventor: Jerry W. Pittman

Patent number: 5326128Abstract: A suspension assembly for attaching wheel assemblies to a frame includes a pair of torsion spring subassemblies adjustably interconnected by a center axle tube to form a unitary axle-like assembly whose torsion spring subassemblies can be adjustably fixed in various desired spaced positions for connection to a selected frame having a particular width. Each torsion spring subassembly includes a torque limiter and further includes an outer tube with a bracket-like mounting member thereon for connecting the outer tube to the side beams on the frame, the bracket member being generally planar in shape and adapted to communicate forces from wheels directly through the torsion spring subassemblies to the frame in a manner that minimizes deformation when the torque limiter engages.Type: GrantFiled: November 10, 1992Date of Patent: July 5, 1994Assignee: CSN Manufacturing, Inc.Inventor: John D. Cromley, Jr.

Patent number: 5088662Abstract: A braking device for a vehicle utilizing a plurality of wheels for motion relative to a surface. The present invention includes a bent axle for supporting at least one of the wheels. The bent axle has a first axle portion being disposed parallel to a y-axis which is perpendicular to an x-axis, the x-axis defining the longitudinal axis of a main structure of the vehicle, the x-axis also defining the direction of vehicle motion. The bent axle includes at least one terminal axle portion angularly disposed from the first axle portion. The first axle portion of the bent axle rotatably engages with the main structure of the vehicle, along an axis parallel to the y-axis. The terminal axle portion of the bent axle rotatably engages with the wheel. Therefore, the wheel rotates in a plane that is not parallel to the direction of vehicle motion.Type: GrantFiled: December 11, 1989Date of Patent: February 18, 1992Assignee: Rockwell International CorporationInventor: Walter T. Appleberry

Patent number: 4956319Abstract: This invention relates to a new ceramic-metal composite body and a method for producing the same. Particularly, a compliant layer composition is utilized for preventing the rupture of a ceramic article and/or the yielding or failure of a metal during the pouring, solidification and cooling of a molten metal which has been cast around the ceramic. A slurry composition for the compliant layer includes plaster of paris, a liquid vehicle and a filler material. The slurry composition is coated on the ceramic article and thereafter is heat-treated to form a compliant layer. Ceramic-metal composite bodies comprising low strength hollow articles and high expansion coefficient metals may be manufactured according to the method of this invention.Type: GrantFiled: January 18, 1989Date of Patent: September 11, 1990Assignee: Lanxide Technology Company, LPInventors: Ratnesh K.
