摘要： 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 described.

摘要： Track assemblies for power machines include a track frame, including a primary portion and a second portion moveable with respect to the primary portion. A plurality of rollers are positioned along the primary portion of the track frame relative to each other and the center of gravity of the power machine to provide an improved capability to compensate for vibration generated as the power machine moves over a support surface. In some aspects, a portion of a tensioning idler is positioned within a cylinder defined by one of the plurality of rollers.

摘要： A controller for a vehicle having a continuous track for vehicle propulsion. The controller is programmed to: process (i) a speed value indicative of a speed at which the vehicle is being driven; and (ii) a time value indicative of a period of time for which the vehicle has been driven at that speed; determine an overheating parameter value based on the speed value and the time value; compare the overheating parameter value with a threshold value, wherein the threshold value is representative of undesirable operation for the continuous track; and generate an output signal for the vehicle in accordance with a result of the comparison of the overheating parameter value with the threshold value.

摘要： A track assembly for traction of an off-road vehicle, such as an all-terrain vehicle (ATV) or a snowmobile, is disclosed. The track assembly comprises a plurality of track-contacting wheels, which comprises: a drive wheel; and a plurality of idler wheels spaced apart in a longitudinal direction of the track assembly. The track assembly also comprises an endless track disposed around the track-contacting wheels. A frame of the track assembly may comprise a hollow frame structure. The hollow frame structure may be dimensioned to impede accumulation of snow, mud, rocks, debris, etc. in the track assembly. The track assembly may comprise interwheel guides between longitudinally adjacent ones of the idler wheels to contact a bottom run of the endless track, and/or fenders adjacent to given ones of the idler wheels. The frame's hollowness, the interwheel guides, and/or the fenders may be realized during molding of a portion of the frame using a blow molding or other fluid-based molding process.
