Abstract: A hose line management system for a tractor-trailer includes a vertical tube rotatably mounted on the truck frame, between the cab and trailer, and a horizontal tube pivotally attached to the upper end of the vertical tube. The truck's electrical cables and air hoses are passed through the tubes and connected to the trailer. The tubes can move in both a vertical and horizontal plane according to vehicle movement to prevent the hoses from breaking or disconnecting. The tubes are biased to return to an original position when no longer stressed by vehicle movement or orientation.

Abstract: A jackknife-prevention system for a tractor-trailer rig wherein the present invention is operable to engage the front brakes of the tractor-trailer tractor so as to oppose and reverse a jackknife movement upon detection thereof. The present invention includes a lateral-acceleration sensor that is mounted in the cab of a tractor trailer and transmits power from a source to a left-side circuit or right-side circuit if the tractor is skidding leftward or rightward, respectively. A steering direction sensor is configured to transmit power from said left-side circuit to both of two stopcock assemblies when steering is leftward or from said right-side circuit to both of two stopcock assemblies when steering is rightward, the stopcock assemblies responding to power input by decompressing both front-wheel brake chambers. This action, allowing the front wheels to roll when steered in the direction of a sideward skid, helps align the tractor with its trajectory.

Abstract: Trailer electrical connector assemblies can facilitate the automatic coupling and decoupling of a trailer. A trailer electrical connector assembly can include a vehicle portion and a trailer portion.

The trailer portion can include a sleeve that is positioned around a coupling mechanism of the trailer and a sleeve ring that forms receivers within which contacts are positioned. When the hitch ball is inserted into the trailer's coupling mechanism, the receivers can be automatically coupled with the guides to thereby form an electrical connection between the vehicle and the trailer.

Abstract: Described herein are methods and systems for controlling differential wheel speeds of multi-independent-wheel vehicles, such as four-wheel-drive electric tractors (4WD-ETs). Specifically, a method comprises determining a target speed for each wheel of the vehicle based on at least the steering input. The linear travel speeds (corresponding to these target speeds) of any two wheels are different when the vehicle turns (steering input deviates from a no-steering baseline) or the same when the vehicle travels in a straight line (steering input is at the no-steering baseline). Each target wheel speed is then used to control the rotational speed of the corresponding electric motor, which independently drives one of the vehicle's wheels. This process of determining the target wheel speeds and independently controlling all electric motors is frequently repeated such that the vehicle can be propelled through the turn at the desired speed with minimal wheel slip.

Abstract: Disclosed are power systems, and power machines employing the power systems, having dual in-line pumps configured to supply hydraulic fluid to respective left and right side travel motors of the power machine. In some exemplary embodiments, pump pintle arm controls and a single centering mechanism for the pintle arm controls are provided. The single centering mechanism is configured to center the pintle arms for each of the two pumps. Also in some exemplary embodiments, a mechanical control linkage configuration allows the separate pump pintle arm controls to be positioned on a side of the pump substantially one behind the other. This allows hydraulic connections to the pumps to be placed on top of the pump assembly, improving the routing of hydraulic hoses in the power machine.

Abstract: A jackknife prevention apparatus configured to be mounted intermediate the trailer and cab of a tractor-trailer rig extending bilaterally wing-like from the tractor's frame rails to which it is hinged horizontally. The jackknife prevention apparatus can swing up or down on its hinge between lowest and highest positions by action of a motor which responds to tractor conditions so as to promote safety, maneuverability and convenience. Specifically, when the tractor is parked, the apparatus tilts down near the ground and constitutes a stairway from ground up to the frame-rail tops. When the tractor is unparked, the apparatus swings up to near horizontal, where it is inactive. If tractor speeds exceed perhaps 20 or 30 mph, the apparatus rises to its highest position where it blocks further nearing of a trailer's front corner to the tractor's cab at a tractor-trailer angle of perhaps 15 to 20 degrees, thereby preventing a jackknife accident.

Abstract: A bicycle includes a transmission having two switchable drives between a driver body on which rear sprockets are positioned and a wheel hub of a rear wheel. The bicycle has actuation elements for switching between drives and operating elements for operating the actuation elements. The bicycle includes only a single front sprocket. The actuation elements are embodied in an electrical version and the operating elements are electrically coupled to the actuation elements. By advantageously selecting the drives of the driver between the cassette housing and wheel hub, a front derailleur may be omitted. The driver allows operation with only little energy, since the chain need not be shifted. consequently, the actuation elements require little energy for changing the drive between the crank axle and the wheel hub of the bicycle, so that it is pre-eminently suitable for these actuation elements and their operation to be executed as an electrical version.
