The front strake having a first edge adjacent the body portion and extending outwardly to a second edge of the front strake that terminates at or inboard of an outboard side of the tire, the front strake defining a lower edge and an upper edge, the lower edge and the upper edge both configured to be positioned forward of the axis of rotation, and tread of the tire positioned rearward of the upper edge is uncovered by the wheel casing.

A tire skirt support assembly for a compactor comprising a bracket and one or more skirt support members. The bracket can be oriented horizontally, and each skirt support member can have a body that is elongate with a first end and a second end opposite the first end. For each said skirt support member, the first end can be fixed to the bracket, and the second end can be below the bracket and is a free end configured to removably engage a skirt via an attachment opening in the skirt.

Mudflap in a wheel arrangement for a vehicle such as a truck or a utility vehicle or a trailer, the mudflap comprising a plate, arranged substantially in a vertical position, the plate being attached to a support in the vehicle, a front side being oriented toward the wheel, and a rear side oriented away from the wheel, the plate having a plurality of holes and closing member(s), wherein each closing member exhibits a rest position in which the closing member closes holes at the rear side thereof, and a deflected position in which a dynamic air pressure pushes the closing member away from its rest position, thereby allowing air to pass through the hole, and thereby reducing the aerodynamic drag of the mudflap.

A resin molded article capable of improving a bonding strength between a first member and a second member is provided. Resin molded article includes first member and second member that is made of a resin, in which the first member and the second member are integrally molded. Resin molded article includes extension section that is formed by second member and that is positioned outward with respect to at least a part of outer edge section of first member. Resin molded article includes gate section that is disposed on extension section and that is a section into which a molten resin raw material flows during molding. First member has area expansion section at outer edge section in contact with extension section and along a direction where the molten resin raw material flows from gate section.

A guard assembly is provided for use with a track assembly for a vehicle. The guard assembly includes a guard body having a rigid portion made of a first polymeric material and a flexible portion made of a second polymeric material different from the first polymeric material. The first polymeric material has a greater modulus of elasticity than the second polymeric material. A vehicle including a guard assembly, namely including a guard body is also contemplated.

A wheelchair barrier attachment device prevents contamination of particles picked up from the ground by the wheelchair, by allowing the barrier between the wheel of the wheelchair and the propulsion rim in which the user must touch to operate the wheelchair.

A tractor (1) has a mudguard device (5) including a cover element (50) suitable to surround at least along an arc of circumference the respective wheel assembly (100) and suitable to act as a separation element along a transverse axis (Y-Y) between the respective wheel assembly (100) and an operating area (200) containing components of the tractor (1). A support system (51) is suitable to attach the cover element (50) to the respective axle (10). The cover element (50) can be guided in movement from a covering position in which the cover element covers the respective wheel assembly (100) to an open position in which the operating area (200) is accessible, and vice versa.

A motor vehicle includes an air duct between a front wheel housing and a side wall of the motor vehicle, the air duct extends between an inwardly directed embossment of the side wall and a wheel housing cover which partially covers the embossment externally at a distance therefrom.

A mud flap for a wheeled vehicle includes an upper mounting portion and an extended protection portion. The extended protection portion includes at least two areas with slotted air flow openings. An upper slot area includes rows of elongated slots with the slots arranged in columns in each row. A lower slot area includes rows of elongated slots with the slots arranged in columns in each row. The slots in the upper slot area have heights that are greater than the heights of slots in the lower slot area. In some embodiments, a middle slot area is positioned between the upper slot area and the lower slot area. The slots in the middle slot area have different heights in different rows. In some embodiments, at least a portion of the slots in the upper slot area is replaced with diagonal mounting features.

A rear wheelhouse vent assembly and a vehicle include a wheelhouse liner. A first edge of the wheelhouse liner defines a cutout that is open along the first edge. The assembly includes a side panel and a duct. The side panel defines a recess, and the wheelhouse liner is disposed along the recess transverse to the side panel to define an open area. The duct is disposed in the cutout. The duct includes a first wall, a second wall and a third wall. The second wall is disposed between the first and third walls. The first and third walls each extend outwardly away from the second wall to respective distal ends to space the second wall from an inner surface of the side panel. The duct is secured to the inner surface and presents a tunnel that vents the open area.
