摘要:
A connection system for connecting a supporting arm to an axle body comprises a first and a second supporting element each having a reinforced region, wherein the first and second supporting elements cooperate to substantially enclose the axle body, and wherein contact regions created between the first and second supporting elements are substantially vertically aligned.

An axle assembly (10) for a wheeled vehicle includes a cylindrical housing (12a) defining a pair of spindle mounting flanges (30). A pair of spindles (16) is secured to the flanges. A plurality of tension rods (60) extend between the spindles at the bottom side of the cylindrical housing and apply clamping forces to the spindles urging the spindles into mounting contact with the spindle mounting flanges and also concurrently couple the flanges to each other. The coupling of the flanges to each other generates a tension force in each tension rod, whereby bending loads exerted by the spindles are shared between the housing and the tension rods.
摘要:
A fabricated vehicle axle is shown to include a main body having an inverted U-shaped configuration. The fabricated vehicle axle further includes a continuous bottom plate welded to the main body. The fabricated axle also includes a first king pin top plate having a reversed curved fork portion welded to the main body at one end thereof. Similarly, the fabricated vehicle axle includes a second king pin top plate having a reversed curved fork portion welded to the main body at an opposite end thereof. Still further, the fabricated vehicle axle includes a first gooseneck part welded to the first king pin top plate and the first end of the bottom plate. Similarly, the fabricated vehicle axle includes a second gooseneck part welded to the second king pin top plate and the second end of the bottom plate.REEXAMINATION RESULTSThe questions raised in reexamination request 90/007,703, filed Sep. 1, 2005 have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e), for ex parte reexaminations, or the reexamination certificate required by 35 U.S.C. 316 as provided in 37 CFR 1.99(e) for inter partes reexaminations.
摘要:
A wheel 100 rotatable about a main axis 106a, including: (a) a frame 111 including multiple supports 114; (b) a first series 150 of rollers 140 radially spaced from the main axis and aligned with a first plane 160a normal to the main axis, the first series of rollers spaced to form a first discontinuous rim; and (c) a second series 152 of rollers radially spaced from the main axis and aligned with a second plane 160c normal to the main axis. The second series of rollers are spaced to form a second discontinuous rim. The first and second planes are aligned parallel to and spaced from one another. Each roller 140 is: (i) rotatable about an axis normal 117 to the main axis; (ii) mounted between a pair of the supports 115; and (iii) has a lateral central cross-sectional diameter greater than the diameter of its end portions. When viewed in side elevation, the effective ground contacting surface of each of the rollers of the first series of rollers overlaps with the effective ground contacting surface of at least one diagonally adjacent roller of the second series of rollers so that the wheel is adapted to make effective ground contact through at least two of the rollers at any one time for effective travel in directions having a component parallel to the main axis. The frame is furthermore incapable of flexing sufficiently to permit the rollers from being removed or dislodged from the frame, but capable of flexing sufficiently under high loads to redistribute load stress throughout the frame.
摘要:
A wheel assembly having multiple small rotatable wheels mounted laterally thereon whereby lateral movement as well as forward and backward movement is provided. A pair of the wheel assemblies are utilized on a hand-propelled wheelchair that can be moved laterally as well as in the standard forward-reverse motion. The wheelchair comprises a frame, one or more axles, a pair of main wheels rotatable on the one or more axles, and a plurality of small rotatable outer wheels positioned laterally on the main wheels.

A powered motor vehicle rear axle 10 is provided that can be coupled with a motor vehicle drive train. The powered motor vehicle rear axle is configured as twist-beam rear axle with two wheel carrying resistant trailing arms that are elastically linked to the motor vehicle structure and a bending resistant, but torsion flexible cross member. Here each of the trailing arms swings around at least one swivel axle. Over its entire length the cross member has a one-piece pipe profile or an open profile. Here it is separate from the swivel axles as well as from the wheel centers when viewed lengthwise from of the motor vehicle. In the area of its both ends the cross member is welded to the trailing arms 12. The cross member is, in particular, generally bent upwards to make space for the installation of at least one module allocated for the drive train, for example for the installation of a drive shaft and a rear axle differential.
摘要:
A suspension mounting system and a method of assembly of the same are disclosed. The system has an axle housing having two hollow arms and an upper portion and a lower portion. At least one suspension bracket is located between the upper portion and the lower portion and through one of the hollow arms.

摘要:
The twist-beam axle (10) comprises a central cross-member (11) compliant to torsion and a pair of trailing arms (12) fixed to side end portions (11a) of the cross-member (11) for articulated connection of the axle to the vehicle body and for support of the rear wheels. Each trailing arm (12) is formed by a pair of first, transversely inner half-shells (18, 19), that is, a front half-shell and a rear half-shell, respectively, securely connected to each other and to the respective end (11a) of the cross-member (11), and by a second transversely outer half-shell (20), securely connected to the pair of first half-shells (18, 19) so as to form therewith a structure having a closed cross-section.
