Abstract: A fastening system having differentiable components includes a first bushing with a first mating feature to be inserted within a first receiver. A first fuse pin with a second mating figure and being configured to shear upon the application of a first predetermined load is configured to be inserted into the first receiver and mate with the first mating feature of the first bushing. The first and second mating features correspond and permit the insertion of the first fuse pin into the first bushing within the first receiver to selectively connect components. The first bushing may prevent the complete insertion of a second fuse pin having a third mating feature into the first receiver. A second bushing having a fourth mating feature may permit the complete insertion of the second fuse pin into the second bushing positioned within a second receiver.

Abstract: A system for remote object handling including a public safety vehicle having a front portion. An articulated arm has a first end and a second end distinct from the first end, the arm being coupled to the front portion at the first end, and has at least one pivot disposed between the first end and the second end. A gripping element is removably coupled to the second end, wherein the gripping element is one of a pincer device, a hand device having at least three fingers or a shovel. A video camera is also coupled to the second end. An arm control is disposed within the vehicle and is operable to control the operation of the arm, the manipulator and the video camera, and a video interface is coupled to the video camera which is operable to display output from the video camera.

Abstract: A drive unit is provided. The drive unit forms a power transmitting path that includes a driving shaft between a wheel/tire assembly and a driving power source provided separately for each wheel/tire assembly, and transmits power via the driving shaft. The drive unit has a weak portion, which is less durable than any other portion in the power transmitting path with respect to external force applied to the wheel/tire assembly, formed on the driving shaft.

Abstract: A method and to a system for controlling a sliding device for a fifth wheel coupling arranged on a towing vehicle, wherein the sliding device includes a substructure having at least one guide rail oriented in the driving direction, a movable slide, which supports the fifth wheel coupling and engages on the guide rail, and a control unit, to which a motorized drive unit for moving the slide and an actuator for fixing the slide relative to the guide rail are connected. The aim was to provide a method and a control system with which a sufficiently large gap width (W) can be set between the towing vehicle and the trailer in a timely manner. This is achieved, among other things, by a method in which a distance measurement is performed to detect an obstruction in front of the towing vehicle, the signal of the measurement is processed into a control signal in the control unit, and a start-up of the motorized drive unit and/or the actuator is initiated therewith.

Abstract: A crash attenuator includes a crash cushion having a front end, a rear end, and a trailer hitch component disposed adjacent the front end. The trailer hitch component is capable of being secured to a mating hitch component located on the towing vehicle, such that hitch components are capable of being rotated relative to each other about a substantially vertical axis. The crash attenuator further includes at least one wheel supporting the crash cushion. The wheel is rotatable about a substantially horizontal axis and is spaced rearwardly from the substantially vertical axis. The crash attenuator further includes at least one restraint element operable between at least a disengaged condition, wherein the crash cushion is capable of rotating about the substantially vertical axis, and an engaged condition, wherein the at least one restraint element constrains rotation of the crash cushion about the substantially vertical axis.

Abstract: An energy-absorbing trailer hitch assembly is provided that includes a receiver tube and an insertion tube. The receiver tube is typically fixedly attached to a motor vehicle and has a set of apertures that affords for a pin to pass therethrough. The tube also has a set of slots adjacent to the apertures, with protrusions between each aperture and its adjacent slot. The insertion tube serves as a trailer hitch and has a set of apertures that align with the set of apertures in the receiver tube. Placement of the insertion tube within the receiver tube affords for a pin to pass through and be held within said apertures. In this manner a trailer may be attached to the trailer hitch and pulled by the motor vehicle. When the trailer is impacted, for example by a rear-end collision, deformation of the pin and/or the protrusions of the receiver tube allow the pin to travel in a forward direction, thereby absorbing energy from the collision.

Abstract: The present invention provides a rollover limiting vehicle coupling apparatus for coupling two vehicles, wherein apparatus is configured to provide stability in certain directions in one mode of operation, and is further configured to prevent transmission of rollover between vehicles in another mode of operation.

Abstract: A safety device (30) is actuatable to uncouple a first vehicle (10) from a second vehicle (12) to which the first vehicle (10) is coupled by a pivotable joint. An actuating apparatus (70, 72) senses and responds to a specified vehicle crash condition by actuating the safety device (30). Preferably, an additional safety device (32) is actuatable to roll the vehicles (10, 12) relative to one another. The actuating apparatus (70, 72) further responds to the specified vehicle crash condition by actuating the additional safety device (32).

Abstract: A combination articulated vehicle damping system for absorbing the kinetic energy of the trail vehicle during a collision. Affixed to the trail vehicle is a damping material retainers that holds a damping material. The back of the damping material retainer engages the rear end of the damping material. A slider frame is slidably mounted in the damping material retainer and engages the forward end of the damping material. A shearable fastener prevents the slider frame from moving relative to the damping material retainer until subjected to a predetermined force. Secured to the slider frame is the connector for coupling the lead vehicle to the trail vehicle. Once the combination articulated vehicle is subjected to a predetermined force, the shearable fastener breaks allowing the slider frame to move and thereby deform the damping material. The deformation of the damping material absorbs the kinetic energy of the trail vehicle.

Abstract: A towing head assembly, designed to be mounted on a tow bar of a towing vehicle, which is structured to innerconnect the towing vehicle to a tow pin of the type normally found on aircraft landing gear. A connecting structure includes a rotatable cam selectively positionable into a clamping or locking position defined by camming engagement of a cam structure with the tow pin of the aircraft forcing it to be clamped between a remainder of the mounting structure such as one or more hook members. The cam structure includes an adjusting feature which adjustably forces a portion thereof into camming engagement with the tow pin so as to overcome wear of the tow pin and ensure a firm, clamping engagement therewith.

Abstract: A tractor-trailer combination has a safety stop arrangement mounted on the trailer coupler base member for limiting relative pivotal movement of the trailer and tractor by engaging in a slot provided in the fifth wheel of the tractor and stopping undesirable movement. If sufficient force is created by the relative movement of the tractor and trailer, the tractor-trailer pin coupling will part before the break point of the safety stop arrangement is reached and the trailer will be separated from the tractor in order to prevent a serious jackknifing situation.

Abstract: A construction vehicle has a pull hook arrangement mounted on a rearward end of a frame thereof for towing purposes. Such arrangement comprises a pull hook and energy absorbing means normally secured between the frame and the pull hook and adapted to break-away from the frame when the load on the pull hook exceeds a predetermined magnitude. The energy absorbing means preferably comprises a tubular member which is tapered-down rearwardly to thereafter permit it to be drawn through an aperture formed in the frame to absorb energy thereby.
