A vehicle comprises a chassis, a seat, a motor, an endless drive track, and a rear suspension assembly supporting the endless drive track. The rear suspension assembly includes a left slide and right slide rail, at least one rear suspension arm being operatively pivotally connected to one of the slide rails and the chassis, with at least one coupling block being connected thereto. A rear stopper is connected to one of the slide rails, the rear stopper being disposed within a range of motion of the at least one coupling block in a first position and being disposed out of the range of motion of the at least one coupling block in a second position. The vehicle includes a control cable and an actuator, the rear stopper moving between the first and second positions when moving the actuator between first and second actuator positions.

A tapered short tunnel for use on a tracked vehicle, such as a snowmobile. The tapered short tunnel has a tapered distal end having a width less than a width of an endless track used on the snowmobile. This tapered portion reduces the snowmobile from catching or grabbing snow in a snow trench, thereby enabling the snowmobile to traverse deeper snow.

A track system for a vehicle (e.g., an all-terrain vehicle (ATV)) in which the track system is configured to enhance traction, floatation, and/or other aspects of its performance, such as, for example, to maintain proper contact with the ground (e.g., even if it is cambered) and/or to better absorb shocks when it encounters obstacles on the ground.

A work machine includes an undercarriage assembly. The undercarriage assembly includes a chassis and a ground-engaging mechanism for rotating around the chassis to move the work machine. A pair of rails is coupled to the chassis. A pair of sliders is coupled to a front-assembly. The sliders are aligned with the rails and movable relative to the rails to facilitate movement of the front-end assembly relative to the chassis.

A remote controlled luggage handler apparatus for loading and unloading luggage from tour buses includes a carrier body having a pair of drive tracks. A multi-axis arm has a base pivot unit coupled to a body top side, a proximal segment coupled to the base pivot unit, a distal segment, and a head pivot unit. A jaw comprises a jaw support coupled to the head pivot unit, a fixed mandible coupled to the jaw support, and a sliding mandible slidably coupled to the jaw support to secure a suitcase between the fixed mandible and the sliding mandible. A CPU, a first transceiver, and a battery are coupled within the carrier body. A remote control is in operational communication with the first transceiver to control the drive tracks and the arm. A charging port is configured to be installed within a storage bay of a tour bus to charge the battery.

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, and a single drive wheel assembly. The drive wheel assembly includes a sub-frame removably securable to the frame in any one of a plurality of longitudinal securement positions on the frame, and a drive wheel rotationally mounted on the sub-frame for rotation about a drive wheel axis. The drive wheel is operatively connectable to the drive axle of the vehicle. A pair of track assemblies is also described. A vehicle having the pair of track assemblies is also described.
