  • Publication number: 20040217572
    Abstract: An axle assembly is provided that includes an axle. The axle assembly may be of an inverted portal axle configuration. The axle includes a boss having a threaded aperture. A suspension component, such as a suspension arm, may be secured to the axle by a fastener received by the threaded aperture. A bracket may be arranged in engagement with the boss between the suspension arm and the axle. The bracket may be used to connect a torsion bar to the axle. The bracket includes an aperture with the fastener disposed within the bracket aperture. The fastener, which is common for the suspension arm and bracket, creates a clamping load on the bracket. Moreover, the suspension arm and the torsion bar bracket share a common boss.

  • Patent number: 6810975
    Abstract: A suspension system for a tracked vehicle, preferably having rubber tracks. The track assembly is mounted on a pivot shaft such that it can oscillate about the axis of the pivot shaft. The suspension system allows the track assembly to move vertically relative to the vehicle chassis to compensate for uneven terrain. For instance the track assembly can compensate for depressions or bumps in the terrain and preclude the chassis of the vehicle from tilting with each minor change in the terrain. In addition, the track assembly movement in the vertical direction provides a much smoother ride than do traditional tracked vehicles. The suspension system of the present invention is provided for use with a pair of track assemblies.

  • Patent number: 6793227
    Abstract: A differential stabilizer arm is provided to reduce rear wheel hop on motor vehicles. A universal joint is securely fastened to the frame or cross member of the vehicle approximately three feet in front of the rear axle. Located atop the universal joint is a box-type saddle arrangement that is lined with polyethylene, also known as Hi-Fax®, to reduce the coefficient of friction. A square tube then slides in and out of this channel in a manner parallel to the centerline or drive shaft of the vehicle. At the opposite end of the square shaft is a V-shaped arm with isolated rubber brushings on the end of each of the two arms. One arm connects to the rear axle housing above the axle, and the other connects to the housing below the axle. In such a manner the invention will follow the axle as it moves through any of the three axes of movement.

  • Patent number: 6766872
    Abstract: A utility vehicle includes a middle axle that is mounted at the end of a bogey beam for flotational movement relative to the frame of the vehicle. The rear axle is carried by a suspension mechanism supported from the frame of the vehicle. The middle axle is formed by a pair of stub axles interconnected by a support beam that is pivotally connected to the rearward end of the bogey beam. The rear suspension mechanism includes a pair of transversely spaced suspension struts interconnecting the frame and a rear axle member having the rear drive wheels mounted thereon. Connecting support links interconnecting the middle and rear axles maintain proper positional spacing between the middle and rear axles.

  • Patent number: 6752235
    Abstract: A driveline assembly module includes a drivetrain assembly that is a rigid, substantially box-like member, that is the main support structure for all the driveline components. An independent suspension system having an associated wheel hub is also attached to the drivetrain assembly. By mounting the driveline components and independent suspension as an integral module, the components are replaced or serviced by replacement of the entire module. Thus, the individual mounting, replacement and servicing of the individual components, each having multiple independent attachment points, is avoided.

  • Patent number: 6491129
    Abstract: An agricultural tractor having a rear suspension with draft compensating geometry to control the compression or extension of the rear suspension in response to a draft load. The draft compensating suspension enables the tractor hitch to be mounted on the suspended frame or chassis of the tractor rather than mounting the hitch to a non-suspended beam axle or locking out the suspension during draft work. The draft load is applied to the chassis by a ground engaging implement. The tractive load and torque at the rear wheels are reacted through the side view instantaneous center of the rear suspension. The placement of the instantaneous center will determine the suspension reaction to the wheel load and torque. Locating the suspension instantaneous center on a line of 100% draft-compensation will eliminate the motion of the suspension due to the draft load. If the instantaneous center is located below the 100% draft-compensation line, the suspension will compress under a draft load.

  • Patent number: 6357769
    Abstract: A vehicle suspension system for mounting to a vehicle chassis includes a subframe which includes two tubular members. Each tubular member has a rear chassis mount and front chassis mount. The tubular member mounts are constructed and arranged to mount to a leaf spring mounting perch on the vehicle chassis. The tubular members are connected by a plurality of cross braces which in turn are connected to a plurality of intermediate tubes. A differential mount connects to a cross brace which is connected to a tubular member. An upper control arm mount and a lower control arm mount connect to intermediate tubes which are connected to a cross brace which in turn is connected to another cross brace. This all connects to at least one tubular member. A self-contained suspension assembly mounts to the subframe at various places. For example, a differential mounts to the subframe at the differential mount and a pair of half-axle shafts connect to the differential.

  • Patent number: 6328322
    Abstract: A drive axle suspension for maintaining a differential pinion gear at a substantially constant position in response to engine torque induced or vehicle roll induced twisting forces acting on the differential axle housing. The drive axle suspension comprises a trailing arm having one end pivotally mounted to the vehicle through a hanger bracket, depending from a frame rail of the vehicle, and another end connected to the vehicle frame rail through an air spring. The trailing arms have a blade-like configuration that permits the blades to twist longitudinally and bend laterally to relieve the axle twisting forces that would otherwise rotate the differential and undesirably rotate the pinion gear, changing its angular orientation.
