Resin plate-shaped mudguards 11 are disposed on vehicle width direction outer sides of left and right side members 7 below a cab. A cab rear member 12 is fixed to a vehicle body frame 5 and extends upward from the vehicle body frame 5 to support a rear end side of the cab from below. Mudguard brackets 17 for supporting the left and right mudguards 11 are fixed to an upper end portion of a support member 15L of the cab rear member 12. The mudguard 11 is disposed forward of the mudguard bracket 17 and supported by the mudguard bracket 17. A BSM radar 10 detects information of an object around a vehicle, is disposed on a vehicle width direction outer end portion behind the mudguard 11, and is fixed to a second bracket 19 of the mudguard bracket 17 via a radar bracket 20.

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 road debris system and apparatus for use with a car or vehicle transport trailer. Embodiments include a transport trailer coupled to a truck. A plurality of resistive mounting brackets are attached to the truck. Embodiments also include a plurality of cantilever rods, a first end of each of the cantilever rods attached to one of the plurality of mounting brackets. The second end of each of the plurality of cantilever rods extend away from the respective mounting bracket. A debris guard is coupled to the plurality of cantilever rods such that an edge of the debris guard distal from the mounting bracket may articulate up and down, and such that an end of the debris guard adjacent a front of the transport trailer may articulate up and down. The debris guard is dimensioned to fill a gap between a back end of the truck and the front of the transport trailer.

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.
