The present disclosure provides a collision energy absorbing apparatus capable of suppressing a peak load at the initial stage of a collision and a load drop immediately after it. The collision energy absorbing apparatus is an apparatus that absorbs collision energy, the apparatus being mounted on a vehicle and including a pressure member, an absorbing member, and a guide part that guides, a moving direction of the pressure member, in which a hole through which the pressure member guided and moved by the guide part enters is formed in the absorbing member, and in an event of a collision, the pressure member is guided by the guide part and a tip part of the pressure member enters the hole formed in the absorbing member while shearing an inner wall of the hole, to thereby absorb collision energy.

A quick-attach mechanism for attaching an implement to the forward end and/or rearward end of a vehicle, such as a tractor used in a tractor-trailer combination, and the like. The quick-attach mechanism includes two laterally positioned female quick-attach sockets on the forward and/or rearward end of said vehicle. The quick-attach mechanisms can be formed into the chassis of the vehicle.

A vehicle frame is provided. The vehicle frame includes a body frame, a subframe mounted to the body frame, and a bumper frame coupled to the body frame. The bumper frame includes a beam having a first end and a second end. The vehicle frame also includes at least one brace coupling the beam to the subframe adjacent to at least one of the beam ends.

A method for joining members according to an embodiment of the present invention includes: providing a bumper stay including two integrated pipe portions extending in an identical direction, the bumper stay including a recess provided between the pipe portions being adjacent to each other, the recess extending in a longitudinal direction of the pipe portions from end surfaces of the pipe portions, a part of the recess serving as a locking portion, and a bumper beam including a rear inclined wall formed with two hole portions into which the pipe portions of the bumper stay are insertable respectively; inserting the bumper stay into the hole portions of the bumper beam until the locking portion abuts on the rear inclined wall; and pipe-expanding an insertion portion of the bumper stay into the bumper beam to join the insertion portion to the bumper beam by press-fitting.

A vehicle crush can adapted to couple a bumper beam to a side rail, including: a hollow box structure including front and rear portions, the front portion including or adapted to be coupled to a bracket assembly adapted to be coupled to the bumper beam, the rear portion adapted to be disposed within the side rail and defining a plurality of lateral holes; and one or more internal sleeves disposed within the box structure and defining a plurality of lateral channels aligned with the plurality of lateral holes of the box structure; the plurality of lateral holes of the box structure and the plurality of lateral channels of the one or more internal sleeves adapted to be aligned with a plurality of holes defined by the side rail when the rear portion of the box structure is disposed within the side rail and collectively receive a plurality of bolts therethrough.
