  • Patent number: 9085209
    Abstract: A suspension system for a vehicle includes a frame mounting bracket for mounting to the vehicle. First and second levers are pivotally mounted to the frame mounting bracket. First and second rubber torsion axle assemblies are rigidly mounted to the first and second levers, respectively. A control arm pivotally connects to the first lever and the second lever. The control arm, and the first and second levers are configured to rotate the first rubber torsion axle assembly and the second rubber torsion axle assembly simultaneously when a static or dynamic force is encountered by the suspension assembly. First and second spindle swing arms can be attached to the first and second torsion axle assemblies respectively with the first spindle swing arm extending forward of the first lever with respect to a direction the vehicle normal travels and the second swing arm can trail the second lever in a “push-pull” configuration.

  • Patent number: 9039034
    Abstract: A suspension system for a vehicle includes a frame mounting bracket for mounting to the vehicle. The suspension includes front and rear rubber torsion axle assemblies. Front and rear lever assemblies are respectively pivotally attached to the vehicle at front and rear lever pivot points. Outer housings of the rubber torsion axle assemblies are each respectively rigidly mounted to the front and rear lever assemblies. A rigid control arm is pivotally connected at one end to the front lever assembly at a front control arm pivot point and its other end is pivotally connected to the rear lever assembly at a rear control arm pivot point. When the suspension assembly encounters a force causing the front lever assembly to rotate in one direction about the front lever pivot point the rigid control arm causes the rear lever assembly to rotate about the rear lever pivot in an opposite direction.

  • Patent number: 8833795
    Abstract: A device for damping vibrations acting on a tracked vehicle is provided, which has a front and rear track roller. Torsion springs are mounted along a vehicle pan. Alternatively, the torsion springs can be subdivided into smaller torsion springs. For the immediate track rollers, a further device is provided in which the long torsion springs which hitherto absorbed the torsion are divided into a plurality of smaller torsion springs and mounted not transversely with respect to the vehicle pan, but in a direction of travel with respect thereto. The torsion springs are functionally connected to one another via drive and/or transmission elements, and are accommodated outside an interior space. In this way, no further installation space is required transversely with respect to and below the vehicle pan, at most in the side region or within a small recess in the pan, a so-called pan niche.

  • Patent number: 8757650
    Abstract: A preferred embodiment of the present invention includes a triple torsion axle system and kit with various features to help reduce or prevent damage that otherwise may occur with large loads. For example, each axle assembly includes larger diameter caps on the ends of each torsion bar to prevent the bar from pulling out of its outer tube during high side loads. In another example, the outer end of the torsion bar has a rounded surface that is fixed to a swing arm so as to better equalize the stress around the weld joint. Additionally, the triple torsion axle is configured such that when the vehicle is unloaded, the middle axle assembly supports more weight than the two adjacent axle assemblies. However, when the vehicle is loaded, all three axle assemblies provide similar support to the vehicle.

  • Publication number: 20040090048
    Abstract: An equalizer bar itself serving as a suspension device of a track-type vehicle has spring effects imparted through torsional deformation relative to vertical oscillatory movements of track frames. Arm portions are fixed in directions opposite to each other in two ends of an equalizer bar main body. Free end portions of the arm portions are individually supported in the track frames to be rotatable in directions opposite to each other. The track frames are therefore regulated in the magnitudes of oscillatory movements according to the spring effects of the equalizer bar main body, whereby travel-time oscillations, oscillatory movements, and/or the like of the vehicle body are sufficiently restrained.

    Abstract: A stabilizer bar apparatus for use in a suspension of a motor vehicle includes a hollow tubular member (22) having first and second arms (24,26) disposed at opposite ends of a center section (28). The center section is adapted to be rotatably attached to a chassis and the first and second arms are adapted to attach to first and second wheel suspensions, respectively. A first radial protrusion (38) is circumferentially formed on an outer surface of the hollow tubular member and extends radially outward from the outer surface to a first predetermined height sufficient to retain the stabilizer bar under lateral loading. Additionally, a stress dispersing formation is (46) formed on an inner surface of the hollow tubular member opposite the first radial protrusion so as to disperse stress that would otherwise concentrate in the hollow tubular member adjacent to the first radial protrusion.

  • Patent number: 4883289
    Abstract: An axle assembly for a vehicle includes a chassis (1) and at least two wheels (2, 3) suitable for coming into contact with ground (4). A unit beam (5) associates the two wheels with the chassis and holds them in two substantially parallel planes (6, 7). A point (10) situated substantially between the two ends (11, 12) of the beam is prevented from rotating relative to the chassis. Two arms (13, 14) are fixed substantially at one of their ends to the end of respective beams. The two wheels are rotatably mounted to the opposite ends of the arms.

    Abstract: An improved road wheel mounting structure. The mounting device comprises a orsion bar fastened a one end to a vehicle hull. The outboard end of the torsion bar is rotatably supported within a sleeve and is connected to a hub.
