An electrical harness system for communicatively coupling a first bus node to a bus controller includes a data bus including a first cable segment and a first data line and a second data line, the first and second data lines extending in parallel along a length of the first cable segment and being electrically coupled together at a first end of the data bus, the first bus node being connected to the first data line and not to the second data line, and first and second termination impedances electrically coupled to the first and second data lines at a second end of the data bus.

A remotely-engaging handle for a fifth wheel hitch system is provided. The remotely-engaging handle may comprise a body and a latching assembly that may be securely attached to the body and capable of engaging with a fifth wheel hitch. The latching assembly may comprise a locking member and an actuating member. The actuation of the actuating member may position a portion of the locking member from an unlocked position to a locked position. The locking member may comprise a latching arm rotating about a pivot point and a biasing member operatively attached the body. The biasing member may bias the locking member into a transitory position. In one embodiment, the actuating member may further comprise an electrically-operated button or a software-based interface. In particular embodiment, the locking member may further actuated by a solenoid and the connecting member may further comprise a wireless device.

The invention is related to the class of small-scale tracked transportation vehicles, which can be used for towing a person and cargo using a sledge, for example. The motorized towing vehicle comprises a frame supporting a caterpillar drive, a platform supporting an engine with a transmission, a luggage space, an assembly for connecting to the object being towed object, a control device, and an object being towed. The caterpillar drive includes a caterpillar track, a metal subframe, a driven shaft and a driving shaft with pinions, and torsion-type wheel bogie. The control device consists of a steering wheel with handles and controls. The object being towed comprises a driver's workplace. The frame consists of a platform and a rigid framework enclosing the platform along the entire perimeter, including the luggage compartment with an additional luggage space above. The design of the frame and platform is asymmetrical relative to the track because of an extension of the platform in one direction. The subframe is in the form of metal side plates connected to the frame with brackets bent into an S-shape. The subframe plates accommodate a track tightening mechanism in the form of an eccentric and self-aligning bearings. An all-weather hood is used for protecting the engine and luggage space. The road performance of the motor towing vehicle has been improved.

The invention relates to a detector arrangement and method for determining a mutual position or a mutual state of motion of at least two structural parts of a mobile work machine. The arrangement comprises detectors configurable to determine at least in one direction of measurement at least two different measured variables in order to determine at least structural-part-specific position or state of motion information for each direction of measurement. The arrangement further comprises a data processing means for receiving measurement signals describing measured variables as well as for determining a mutual position or state of motion of the structural parts on the basis of the structural-part-specific position or state of motion information.

An articulated vehicle assembly comprising a master vehicle having a master steering system and an onboard sensor arrangement configured to monitor at least said master steering system; a slave vehicle having a slave steering system and an onboard actuator arrangement configured to manipulate at least said slave steering system; an articulation system for articulating in a queue the master and the slave vehicles along a common longitudinal axis; and a processing unit configured to receive input signals from the onboard sensor arrangement and produce corresponding output signals to the onboard actuator arrangement to manipulate said slave steering system so as to maintain the master vehicle and the slave vehicle aligned along the common longitudinal axis, at least when the master vehicle performs a turn on a horizontal plane.

An improved cargo dolly for transporting cargo is described having a mobile dolly frame, a main shaft on the frame, a lever proximate to a first part of the frame (where the lever is movable relative to the frame and in responsive communication with the main shaft), a first set of transfer sprockets mounted to the main shaft, a secondary shaft rotatably disposed at a second part of the frame (where the first part is remote from the second part), a second set of transfer sprockets mounted to the secondary shaft, a chain disposed about the first set of transfer sprockets and the second set of transfer sprockets, and a locking pin having a first end fixed to the secondary shaft and a second end configured as an angled latch. Rotation of the lever responsively causes the locking pin to remotely rotate at the second part of the frame.

A tractor-trailer is disclosed, with associated apparatuses. A tractor may include a tractor air duct disposed underneath a cab. The tractor air duct may extend between a front opening at a front of the tractor and a rear opening at a rear of the tractor. A trailer may include a duct system that receives airflow from the rear opening of the tractor air duct and directs the airflow to a location behind a cargo compartment. An air distributor may be disposed behind the cargo compartment. An air distributor may include a fairing with openings, so that airflow from the duct system enters a space between the cargo compartment and the fairing, and exits the openings behind the trailer.

A system and method for braking a tractor-trailer assembly is provided. The method includes generating a tractor brake pressure for application to a tractor brake for braking a tractor wheel, determining a tractor brake rate based on one or more of the generated tractor brake pressure, one or more parameters of the tractor brake, one or more parameters of the tractor wheel, one or more parameters of a final drive, and a mass of the tractor, and determining a trailer brake pressure applied to a trailer brake of a trailer wheel of a trailer, based on the determined tractor brake rate.
