    Abstract: A track assembly for a vehicle includes: a frame; a plurality of track-contacting wheels; an endless track disposed around the track-contacting wheels; a rotation limiting device for limiting rotation of the track assembly relative to a vehicle frame; a connection bracket for connecting the rotation limiting device to the frame; and a bushing assembly slidably connecting a device connecting end of the connection bracket to an elongate support of the rotation limiting device. The bushing assembly includes an inner bushing slidably mounted to the elongate support, an outer bushing affixed to the device connecting end, and a resilient element connected between the bushings. The resilient element is resiliently deformable such that: the inner bushing is rotatable relative to the outer bushing such that an inner bushing axis can be angled relative to an outer bushing axis; and the inner bushing is axially movable relative to the outer bushing.

    Abstract: A support structure having at least one connecting member, a shaft, at least one axle transversally connected to the shaft and at least one resilient member for connecting the at least one support wheel assembly to a frame of a track system is disclosed. The at least one resilient body defines an aperture, in which one of first and second portions of the shaft is received, and has an inner portion that is fixedly connected to the one of first and second portions and an outer portion that is fixedly connected to the at least one connecting member. Upon resilient deformation of the at least one resilient member, the shaft is rotatable, and the at least one axle is pivotable, about the longitudinal axis. The at least one resilient body biases the shaft toward an initial position upon rotation thereof. A track system having the support structure is also disclosed.

    CPC classification number: B62D55/108 ,  B62D55/10

    Abstract: The present disclosure relates to a tandem walking beam suspension system which comprises a main walking beam pivotably mounted to the vehicle sub-frame, a first pair of spaced apart and parallel secondary walking beams pivotably mounted about the main walking beam first end, a second pair of spaced apart and parallel secondary walking beams pivotably mounted about the main walking beam second end, a first pair of rollers rotatably mounted in-between and to the first pair of secondary walking beams, and a second pair of rollers rotatably mounted in-between and to the second pair of secondary walking beams, the first and second pairs of rollers being configured to roll along the track when the track-mounted vehicle is in displacement. The system may further comprise a compression device connecting the sub-frame and the main walking beam such as to provide vertical displacement of the main walking beam relatively to the sub-frame.

    Abstract: A multi-member frame assembly for a track system includes a pivot pin defining a pivot axis, a leading frame member pivotally connected to the pivot pin for pivoting about the pivot axis, and a trailing frame member pivotally connected to the pivot pin for pivoting about the pivot axis, the trailing frame member pivoting independently from the leading frame member. A resilient member is pivotally connected to the leading frame member and to the trailing frame member. The resilient member extends generally vertically between the leading frame member and the trailing frame member. A track system having a multi-member frame assembly is also described.

    Abstract: The invention relates to a tracked vehicle (V1, V2) comprising a vehicle body (20; 120), at least one track assembly (10) and a suspension device (S). Said track assembly (10) is arranged to be supported by said vehicle body (20; 120) by means of said suspension device (S). Said track assembly comprises a track support beam (12) for supporting a plurality of road wheels (16), an endless track (14) being disposed around said road wheels. Said suspension device (S) comprises a leaf spring arrangement (30; 130, 142, 144) having portions transversally arranged relative to the longitudinal extension of the vehicle. Said leaf spring arrangement comprises L-shaped leaf spring members (30; 130), each leaf spring member (30; 130) having a first portion (32; 132) attached to said vehicle body (20; 120), a second portion (34; 134) attached to said track support beam (12) and a transition portion (36; 136) there between, so that compressive and tensile stresses are located to said transition portion (36; 136) for generating a compressive action in said transition portion.

    Abstract: The present invention relates to a suspension arrangement for a tracked vehicle. The suspension arrangement includes a road wheel arm having a wheel axle portion for supporting a wheel of the vehicle and a pivot axle portion. The road wheel arm is pivotably journalled at the pivot axle portion to a housing that is fixable to the vehicle body. A torsion bar is connected to the pivot axle portion and a torsion tube is arranged to be connected to the vehicle body, with the torsion bar running through the torsion tube and arranged to be connected to the torsion tube. The modulus of elasticity of the torsion tube material is lower than the modulus of elasticity of the torsion bar material such that the maximum suspension travel is increased.
