An undercarriage for farm wagons and similar vehicles in which the frame of the vehicle is mounted on one or more axles by units at each end of the axles, each unit consisting of plates connected to the axle, a plate connected to the frame and a member of elastomeric material bonded to the facing surfaces of the axle and frame plates to form the primary support at each end of the axle for the frame. The elastomeric material may be rubber and is preferably of a parallelogram shape in vertical cross sectional direction with the low vertical side being connected to the axle plate and the high vertical side being connected to the frame plate. Second axle and frame plates may be employed to which the first axle and frame plates are rigidly secured by bolts or other securing means. The units supporting the frame on the axle are preferably used in pairs in conjunction with tandem axles and, if brakes are used on one or both of the axles, a torsional bar means, including a resilient member, interconnects the two axles.

An undercarriage for farm vehicles having a frame: comprising an axle extending transversely beneath the frame, wheels on each end of said axle, a support assembly near each end of said axle forming the principal support for the frame of the vehicle and connected to said axle and to a frame member of the vehicle, each assembly including forward and rearward vertical plates disposed at right angles with respect to the axle and secured to the forward and rearward sides of said axle, a vertical plate secured to the frame member and spaced inwardly and upwardly from said forward plate, a vertical plate secured to the frame member and spaced inwardly and upwardly from said rearward plate on said axle, said plates all being on planes substantially parallel to one another, and an elastomeric member disposed between said forward axle plate and respective frame plate and an elastomeric member disposed between said rearward axle plate and respective frame plate, and said elastomeric members being firmly bonded to said plates for reaction to shear forces between the respective vertical axle and frame plates.
