Techniques are directed to utilizing a suspension protector to deflect debris away from a set of suspension components of a tracked vehicle. The tracked vehicle includes a vehicle body, a suspension, and a set of suspension protectors. The suspension couples with the vehicle body and is constructed and arranged to control movement of the vehicle body using tracks. Each suspension protector couples with the vehicle body and is disposed a predefined distance from a respective wheel of the suspension to deflect debris thrown from the respective wheel and a respective track away from a respective set of suspension components of the suspension.

Embodiments of the present disclosure describe a snowmobile including an engine mounted on the chassis, a drive track in contact with the chassis, and a drive train, operatively interconnecting the engine with the drive track for delivering propulsive power to the drive track. The drive train includes a driveshaft, comprising a tubular driveshaft including two or more interior channels, the channels positioned in a substantially longitudinal orientation, two or more sprocket driving features on an exterior surface of the tubular driveshaft, and one or more fitting components, positioned at one or more distal ends of the driveshaft.

A snowmobile including a chassis including a tunnel; a motor; at least one ski; an endless drive track; a rear suspension assembly including: a front suspension arm; a rear suspension arm; a pair of slide rails; a first rear shock absorber connected between the front suspension arm and the slide rails; and a second rear shock absorber connected between the rear suspension arm and the front suspension arm or the slide rails; at least one sensor for sensing an angular position of the front suspension arm or the rear suspension arm relative to one of the tunnel and a component of the rear suspension assembly near at least one of the front suspension arm and the rear suspension arm; and a controller communicatively connected to the sensor to receive electronic signals therefrom representative of the angular position.

A track kit for a vehicle (2), having two track assemblies (1,1′), each track assembly having an endless track (5), a front idler wheel (8), an intermediate support member (6) with at least one track engaging element (7), a rear idler wheel (9), a drive wheel (10), at least one swing arm (11,12) and a shock absorber connecting assembly (13,14), wherein the endless track (5) has an external side featuring ground lugs (15) for ground engagement and an internal side featuring drive lugs (16) for engagement with the drive wheel (10), and the internal side is circumferentially trained around and in contact with the front idler wheel (8).

A wheel of a track system for traction of a vehicle (e.g., an agricultural vehicle) may be configured to protect a track of the track system by reducing stress induced in the track by the wheel. For example, a circumferential surface of the wheel may be uneven (e.g., curved) in a widthwise direction of the wheel (e.g., to have a crown) and/or a covering of the wheel may be asymmetrical about a midpoint of the covering in the widthwise direction of the wheel (e.g., include corners that are shaped differently).

The invention relates to a welding technical field and provides a crawling welding robot. The crawling welding robot includes a vehicle chassis and two crawler wheels connected to two opposite sides of the vehicle chassis, respectively, wheel carriers of two crawler wheels are movably connected with the vehicle chassis. In this way, when the crawling welding robot moves on a non-planar surface for welding, the two crawler wheels can freely adjust its posture relative to the vehicle chassis to adapt to the surface for welding and improve a degree of fit between the two crawler wheels and the surface for welding, making the moving direction of the crawling welding robot easier to be controlled and reducing a probability of the crawling welding robot slipping or falling from the surface for welding.

A kit and corresponding method can be used to convert wheels of a power machine to track assemblies, such as to convert a four-wheeled power machine to a quad track power machine. A stub shaft (346) can be secured to an axle (328) of a power machine (300) and can be configured to support a track frame (366) of a track assembly in place of a wheel (319). A bearing (368) can be secured to the stub shaft (346) and a bushing (376) can engage the axle (328) to rotatably support the track assembly relative to the axle (328). Pieces of a segmented sprocket (378, 380) can be separately secured to a hub (306) of a power machine (300) to help install and drive a track of a track assembly.

A track kit for a vehicle, the track kit having two track assemblies, each track assembly featuring an endless track and a pinch wheel in contact with the external side of the endless track, the pinch wheel having a pinch wheel axle being rigidly connectable to a chassis of the vehicle.
