摘要： A track system for traction of a vehicle (e.g., a snowmobile, an all-terrain vehicle (ATV) etc.). The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track system may have features to enhance its traction, floatation, and/or other aspects of its performance, including the track that may comprise reinforcing material (e.g., reinforcing polymeric material) that is stronger (e.g., stiffer, harder, and/or more resistant to wear) than elastomeric material of the track, such as to improve rigidity characteristics of the track, reduce noise generated by the track system, improve a resistance to wear of the track, enhance heat management (e.g., improve heat dissipation or reduce heat build-up) within the track, and/or reduce a weight of the track. The reinforcing material may be provided as one or more thin layers constituting at least part (e.g., of a periphery) of one or more components of the track (e.g., a carcass, traction projections, and/or drive/guide lugs).

摘要： A heat exchanger assembly has a front portion, a middle portion rearward of the front portion, a rear portion rearward of the middle portion, a top part and a bottom part disposed below the top part. At least one of the front and rear portions is curved from the middle portion. The at least one of the front and rear portions extends below the middle portion. The bottom part is joined to the top part. At least one of the top and bottom parts defines a recess. The top and bottom parts define therebetween a passage formed in part by the recess.

摘要： A track system for traction of a vehicle, such as an all-terrain vehicle (ATV), an agricultural vehicle, etc. The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track system may be configured to facilitate adjustment of certain aspects of its operation, including, for example, how it is positioned and/or can move relative to a frame of the vehicle, based on one or more factors, such as, for instance, a user's preferences (e.g., riding style, desire to “feel” the ground, etc.), an environment of the track system (e.g., a profile of the ground, such as a slope or steepness or a levelness of the ground; a compliance of the ground, such as a softness or hardness of the ground, etc.), a state of the track system (e.g., a speed and/or a direction of motion of the track, etc.), a state of the vehicle (e.g., a speed and/or direction of the vehicle, etc.), and/or any other suitable factor. For instance, the track system may comprise a control mechanism configured to adjust an anti-rotation device that is configured to restrict movement of the track system relative to the frame of the vehicle. The control mechanism may be configured to adjust the anti-rotation device in response to a command, which may be input via a user interface or automatically generated by a controller.
