Abstract: A vibration-proof structure for axle beam of a motor vehicle has an axle beam composed of a long cylindrical body of a letter U-shaped section opening downwards, which is disposed in the width direction of the motor vehicle. Axles are provided at both ends of the long cylindrical body, a stabilizer bar is disposed in the center of an interior of the long cylindrical body so as to connect the both ends of the long cylindrical body, and at least one vibration-proof rubber body is interposed between an inner wall of the axle beam and the stabilizer bar from the underside thereof in elastic contact therewith. The vibration-proof rubber body has an engaging member for engaging the vibration-proof rubber body with the axle beam or the stabilizer bar. The vibration-proof rubber body can be easily installed within the axle beam after the assembling of the axle beam and the stabilizer bar.

Abstract: The invention relates to a U-shaped semi-rigid axle for a vehicle. The axle comprises a transverse portion pivotally connected to the body of the vehicle and two arms serving to mount stub axles on which the wheels are fixed. It is formed of a one-piece tubular structure, the central region forming the transverse portion (3) being so profiled as to present at least one double-wall flange portion, a bent region (12, 13) being provided at each end of the transverse portion, each bent portion being extended by an arm (14, 15) at the end of which is provided the fixing for the stub axle. The invention also relates to a process for producing the foregoing axle. The axle according to the invention can be used in particular as the back axle assembly of a motor vehicle.

Abstract: A roller skate undercarriage including a roller carrier having three or more pairs of rollers attached by screws to the upper structure of a roller skate or to the blade of an ice skate. The carrier has holes, one group of holes at the front, one group of holes at the rear and one hole between the front and rear groups to hold roller hubs. The center axes of the holes in the carrier and of the axle pins inserted through them are staggered with respect to the central axes of the roller hubs mounted on the axle pins so that the height of the rollers may be changed with respect to the roller carrier by turning the roller hubs. In this way the roller skate can be individually adapted to the user and the purpose of use.

Abstract: A unitary tubular axle (12) is formed to include an end (18) having a support section (22) of a completely solid cross section located between a generally vertical kingpin bore (24) and a tubular intermediate portion (16) of the axle. Both ends (18) of the tube are formed with such an end construction to provide a unitary front axle for both wheels. Forming proceeds by initially reducing the size of the outer tube diameter at an end thereof while maintaining roundness. Axial forging of the tube end preferably by a closed die having a semispherical closed end then provides an axle end having a solid cross section and a distal semispherical shape. Subsequent axial forging of the solid tube end by another closed die then provides upper and lower projections (26, 28) in which upwardly and downwardly facing holes are then forged to increase the width thereof while leaving a web between inner ends of the holes.

Abstract: A unitary axle of an elongated tubular construction preferably made from heat treated steel so as to be light weight with high strength. Two embodiments of the axle each have a first vehicle mounted end and a second wheel supporting end as well as an intermediate portion having an I-beam section whose combined height and width is less than the combined height and width of the intermediate axle portion adjacent the second axle end. Upper, lower, and spaced side walls of the intermediate axle portion have a uniform thickness and the side walls are deformed inwardly to form the I-beam section preferably so as to have inner sides thereof engaged with each other. First and second bends in the axle adjacent the first and second ends thereof allow it to be used in an overlapping relationship with another bent axle. A rectangular section of the intermediate axle portion is located between the I-beam section and the second axle end.

Abstract: An offset spindle and spindle support for a mobile home axle is disclosed, in which the wheel spindle is vertically offset with respect to a conventional axle tube. The offset support comprises a generally cup-shaped stamping and utilizes the backing plate of the brake to form a box-section, low-cost high strength offset support for a forged wheel spindle.

Abstract: A nondriven axle suitable for use on trailers, trucks and the like is strengthened by plastically deforming at least a portion of the axle beam to form residual stresses in the axle beam which will resist loads impressed on the axle by the vehicle.
