The invention relates to a subassembly for a vehicle, the subassembly comprising a chassis (50) assembly and a front body module (10). The front body module (10) is attachable to a forward portion of the chassis (50) assembly. The front body module includes a side portion (20) which extends outwardly beyond the chassis in a transverse direction. A stay (40) is provided which extends transversely outwardly from the chassis assembly (50) to support the side portion. One of the front body module (10) or the stay (40) is provided with a connecting member (30) which extends in a substantially longitudinal direction. The other of the stay (40) or front body module is provided with a corresponding longitudinally aligned aperture (42) for receiving the connecting member in use to support the side portion (20) of the front body module (10). A method of assembly is also disclosed.

A structure of an underrun protection bound to a plurality of brackets disposed at the front or rear portion of a frame of a vehicle is disclosed. A hollow having a closed section is defined by a distal face of a longitudinal direction of the vehicle, a proximal face of the longitudinal direction, an upper face, and a lower face. Lightening holes are formed on at least one of the upper face and the lower face of the underrun protection.

A clamp assembly is provided for securing a panel or fairing to an I-beam, and comprises a pair of side blocks and a clamping block having a central body and a flat surface at at least one end of the central body. The side blocks and the clamping block are secured together using a single bolt. The flat surface at the end of the central body is positioned at an angle to the central body, so as to provide an angled surface for mounting of a fairing.

A reinforcement structure (10) comprising an inner member (14) at least partially secured within a shell (12), wherein the inner member is secured within the shell so that one or more abutment portions (18) of the shell are positioned in receiving portions (20) of the inner member, to create at least a partial press-fit condition between the inner member and the shell.

A side underride guard for attachment to the underside of a trailer comprising two guard rails longitudinally positioned below the outer sides of the trailer, with each guard rail attached to the trailer by a plurality of vertical support members and with the two guard rails attached to each other and the trailer by a plurality of diagonal support members. The side underride guard further supports and incorporates an aero skirt for reducing trailer drag.

A semi-trailer is provided, including a wheeled chassis having at least one wheeled axle at a rearward end and a retractable support at a forward end, a body comprising a cargo deck and an underride guard assembly that is movable in response to an upward force applied thereto.

A safety mechanism for use on a vehicle is provided. The safety mechanism comprises a buffer and a sensor that is configured to send an electrical signal to processing circuitry in the vehicle when the sensor is activated. Sufficient movement of the buffer activates the sensor. A drive line may also be provided with the buffer connected to the drive line. Movement of the buffer may cause rotation of the drive line, and sufficient rotation of the drive line may activate the sensor.
