Abstract: The first suspension member is pivotally connectable to a frame assembly of the track system and defines a receptacle. The second suspension member is pivotally connectable to the frame assembly, extends at least partially within the receptacle, and is moveable relative to the first suspension member. The resilient member has a first surface that is generally fixedly connected to the second suspension member and a second surface that is generally fixedly connected to the first suspension member. The first and second suspension members have a first position, and in response to the first and second suspension members moving relative to one another, the resilient member biases the first 10 and second member toward the first position. A track system is also disclosed.

Abstract: A track system for a vehicle having at least three axles is disclosed. The track system includes a frame to which sprocket, idler and support wheel assemblies are connectable, an endless track and a pivoting assembly. The pivoting assembly has a casing connectable to a second axle and at least one pivotable member that has first and second portions respectively pivotally connected to the casing and to the frame. The at least one pivotable member is pivotable between first and second positions about a longitudinally extending pivot, in response to which the first portion is displaced laterally relative to the second portion, and pivotable between third and fourth positions about a lateral pivot axis in response to which the first portion is displaced longitudinally relative to the second portion. A pivoting assembly, a pivoting assembly including a resilient assembly, and a vehicle having the track system are also disclosed.

Abstract: The invention relates to a tracked vehicle comprising a vehicle body and a track assembly pair. Said track assembly pair is arranged to suspendedly support said vehicle body allowing relative movement between said vehicle body and each track assembly (21) of said track assembly pair. Each track assembly (21) comprises a track support beam (22) configured to support a plurality of road wheels (23, 23a), a drive wheel (24), and a motor (110) for operating said drive wheel (24), an endless track (25) being disposed around said road wheels (23, 23a) and drive wheel (24). Said motor (110) is fixedly arranged to said track support beam (22). Said motor (110) is arranged in connection to the drive wheel (24) such that a motor axle essentially coaxially coincides with a centre axis (Z) of the drive wheel (24).

Abstract: The invention relates to a deflector arrangement (100) for a tracked vehicle (V). Said tracked vehicle (V) comprises at least one track assembly (T1, T2) comprising two end wheels (1, 2) in the form of a front wheel (1) and a rear wheel (2), and further a plurality of road wheels (3) there between. At least one of the front wheel (1) and rear wheel (2) is a drive wheel (1) and at least one of the front wheel (1) and rear wheel (2) is a tension wheel (2). The track assembly (T1, T2) further comprises an endless track (4) disposed around said end wheels (1, 2) and plurality of road wheels (3). Said deflector arrangement (100) is configured to reduce ingestion of undesired material from the ground (G) into said track assembly (T1, T2) and remove such undesired material from said track assembly (T1, T2). Said deflector arrangement (100) is associated with an end wheel (1, 2) and is resiliently suspended and biasedly arranged so as to strive towards the inner surface (4a) of the endless track (4).

Abstract: A track assembly is to be mounted on a drive axle of a vehicle. The track assembly has a frame, at least one leading idler wheel mounted to the front of the frame for rotation about a transverse leading idler wheel axis, at least one trailing idler wheel mounted to the rear of the frame for rotation about a traverse trailing idler wheel axis parallel to the leading idler wheel axis, a single drive wheel assembly, and at least two slide rails. The slide rails have corresponding forward-facing portions, central portions, and rearward-facing portions. The forward-facing portions project from the front ends of the central portions by a projection that is greater than a length of the central portions. A vehicle having the track assembly is also encompassed. A kit of track assemblies is also encompassed.
