Disclosed herein is a wheel shield apparatus that includes a pair of elongated parallel tube members in perpendicular engagement with a pair of short parallel tube members, at least one removable side of the wheel shield apparatus is operable to be temporarily opened or removed such that the wheel shield apparatus may be placed around a wheel of a neurosurgical microscope or some other type of heavy wheeled machinery and the removable side may be placed in a closed position such that the wheel shield surrounds the wheel. Each of the pair of elongated parallel tube members and/or each of the pair of short parallel tube members comprises a cavity configured to receive a ballast material to provide sufficient weight to ensure that the wheel shield apparatus contacts the floor such that cables along the floor are pushed out of the way by the wheel shield apparatus and prevented from being run over while the machinery is being transported.

Particular embodiments disclosed herein provide a retractable guard assembly coupled to a caster of a mobile equipment, comprising a housing and one or more guards at least partially disposed in the housing. The one or more guards are independently movably coupled to the housing. The retractable guard assembly further comprises corresponding one or more biasing elements coupled to the one or more guards and to the housing for biasing the one or more guards towards a fully deployed state. When the one or more guards are in the fully deployed state, contact between a fixed object and a portion of the one or more guards disposed outside the housing causes the one or more guards to transition into a retracted state, and when the contact is removed, the corresponding one or more biasing elements cause the one or more guards to transition into the fully deployed state.

Ground compaction machine, which can be a rubber-tired roller, operable to compact ground in a working direction is presented, along with a wheel cover for the same. The machine can have a machine frame and a chassis supporting the machine frame. The machine frame having a front chassis portion and a rear chassis portion. At least one of the front chassis portion or rear chassis portion has at least two chassis units, each chassis unit being rotatable about a distinct steering axis. Each chassis unit having at least one wheel, and a wheel cover, which is formed for thermal insulation of the chassis units from the external surroundings, the wheel cover comprising at least two wheel cover units, and a wheel cover unit being arranged on each chassis unit, which is configured to be rotatable about the respective distinct steering axis together with the respective chassis unit.

A variable air hole covering flap device is provided and selectively opens or closes an air hole formed in a wheel deflector or a wheel cover to allow air to be introduced toward a brake. The air hole is opened only when brake cooling of a vehicle is more necessary than aerodynamic performance of the vehicle to properly control the aerodynamic performance and the brake cooling performance of the vehicle as necessary.

According to a link mechanism type variable wheel deflector applied to a vehicle, a deflector coupled to a cover plate using a hinge boss as a rotation center can be operated using traveling resistant wind as a driving source, a piston receiving the linear movement of a link shaft by a moment arm rotated with the deflector can unfold the deflector while compressing an elastic member, and an elastic restoring force of the elastic member can be applied to the piston to return the link shaft and the moment arm to fold the deflector, thereby strengthening the repeated durability of the elastic member compared to the rotating motion of the spring, and in particular, the rotating motion and the linear motion can be implemented by the link motion mechanism apparatus connected to the deflector, thereby implementing the high durability performance with the low-cost mechanical structure.

In an embodiment a mobility vehicle platform includes a body part open toward an upper side and configured to receive a cabin at the upper side and a wheel part detachably connected to the body part, wherein the wheel part includes a steering member rotatable about an axis extending in an upward/downward direction, a wheel member connected to the steering member and configured to contact a ground surface, and a coupling member, into which the steering member is inserted, and detachably mounted to the body part, wherein the body part includes a body member configured to receive the cabin at an upper side thereof, and a protruding member coupled to the body member to protrude toward an outside of the body member, and to which the coupling member is coupled, and wherein the coupling member includes a first coupling part extending upwards and a second coupling part extending from an upper end of the first coupling part toward the body part.

A vehicle includes a vehicle body defining a front wheel well. The vehicle body includes a rear wall vehicle-rearward of the front wheel well. The vehicle includes one or more cables supported at the rear wall. The cables are movable from a slack position to a taut position. The vehicle includes a pyrotechnic actuator operatively coupled to the cables to move the cables from the slack position to the taut position upon actuation of the pyrotechnic actuator.

A track work vehicle includes a track system. The track system includes a drive wheel supported by an axle housing that drives a continuous ground-engaging track, a saddle assembly that guides the track about the drive wheel and an undercarriage frame that supports one or more idler wheels that guide the track along a ground surface. The track work vehicle includes a fender assembly that includes at least one fender coupled to the track system to overlap a portion of the track.
