Embodiments of the disclosure include a mud flap for a vehicle having a mounting section and a barrier section. The barrier section is configured to deflect matter discharged from a tire during vehicle operation. The width of the mounting section is greater than the width of the barrier section. The mounting section optionally includes a first set of mounting features, each of the mounting features forming a recess or aperture. One mounting feature of the first set of mounting features is arranged at and/or beyond a widthwise extent of the barrier section width. The one mounting feature is also arranged at least partially within a portion of the mounting section width extending outwardly from a widthwise extent of the barrier section width. Further embodiments include mounting a single wide mud flap on a vehicle configured to receive a dual wide mud flap

Embodiments include a mud flap having a barrier section configured to intercept and deflect matter discharged from the tire when rotating during vehicle operation. The barrier section including a plurality of horizontal louvers, each horizontal louver forming an elongate member having a length extending primarily in a direction of the mud flap width, where the plurality of horizontal louvers are spaced apart in the direction of the mud flap height in the form of an array, where the plurality of horizontal louvers are configured to intercept and deflect matter of a minimum size traveling along any linear trajectory path from the outer circumference of the tire/wheel assembly towards the front side of the mud flap while substantially maximizing the spacing between adjacent louvers to minimize aerodynamic drag. Other embodiments provide a method of using the mud flap.

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.

Embodiments provide an aerodynamic fairing system that may comprise a base configured to mount to a vehicle, an arm coupled to the base at a proximate end and extending laterally, and a fairing mounted to the arm having an inboard and an outboard surface. The fairing outboard surface may provide an aerodynamic outer surface to direct flow to an angle to the rear. The arm may a fixed or adjustable length arm. The arm may provide a mounting area for a mud flap such that aerodynamic system may act as a mud flap hanger. Embodiments also provide an adjustable mud flap hanger.

A mud flap lifting system specifically for a live bottom type trailer vehicle in which asphalt or similar is dispensed from the rear of the trailer load box for a paving operation using a paving machine in tandem with the trailer. Pneumatic lift cylinders on each side of the trailer load box are used to retract and extend cables running rearwardly from the cylinders to and through cable guides positioned vertically above the mud flaps. The cables are operable to pull or lift the lower portions of the mud flaps upwardly and outwardly into curved configurations located above a paving machine roller as it engages the rear wheels of the trailer, and at a height designed to engage the paving machine hopper as it engages the trailer.

A mud flap system is provided comprising a mounting device having a top and bottom including a walled recess extending into an inner volume of the mount and exiting out the bottom. The assembly also includes an elongated suspension bracket having a proximal end to the recess, a distal end defining a length and a thru slot running along the length, a stem extending from a bottom of the bracket at the proximal end, enabled to be inserted into the recess and out of the mounting device. A mud-flap is provided having a top having a thickness and a bottom of the mud flap is inserted through the slot and the thickness at the top suspends the mud flap until force applied to the mud flap causes the thickness at the top to deform and pass through the slot thereby releasing the mud flap from the suspension bracket.

A fender assembly having a non-metallic fender panel configured in a curved manner generally prevents material from accumulating on surfaces thereof, reduces weight of the vehicle, and provides a necessary level of protection from flying rocks and other debris that the wheels of a truck may generate. A non-metallic material is used to form the fender panel, which has a desired level of strength, durability, pliability and coefficient of friction. By carefully selecting this material, the fabrication and installation of the fender assembly is further simplified, thus providing additional efficiency. When applied to a cement mixer truck, the curved fender assembly is particularly beneficial as it provides the necessary level of protection, while also discouraging a build-up of concrete on any surface since the non-metallic material will not generally allow concrete to adhere to the surface.

A tire inflation system integrated with vehicle aerodynamic and wheel-end components, such as fairings, wheel covers and mud shields. Fluid conduits may route pressurized fluid from a fluid pressure source to a rotary union mounted at a wheel end. The fluid conduits may be routed along or through various aerodynamic and wheel-end components.

An apparatus (10) for a trailer (12) is provided that has a trailer skirt (14) configured for attachment to the trailer (12). A majority of the outer surface length of an outer surface (16) of the trailer skirt (14) is oriented at a 3-7 degree angle to the longitudinal direction, and the majority of the outer surface length extends inboard in the lateral direction upon extension forward of the trailer skirt (14) in the longitudinal direction. An overall length/overall height ratio of the trailer skirt (14) is 6 or less. The trailer length in the longitudinal direction is at least 10.668 meters (35 feet). A majority of the outer surface length is located rearward of a longitudinal midpoint of the trailer. A rib cover (74) is present and is located higher than a bottom edge of the trailer skirt (14) in the height direction.
