摘要： A traction saddle disposed on a tractor for connection with a traction pin of a trailer, is provided. The traction saddle includes a base, a gear set, and a damper. A gear carrier of the gear set fixes axial centers of the planetary gears of the gear set, the planetary gears are meshed with an inner ring gear of the gear set, and the inner ring gear is fixed to the base. The gear carrier is used for fixing the traction pin to rotate with the traction pin. The planetary gears are meshed with one end of a sun gear of the gear set to drive the sun gear to rotate, and the damper is connected to the other end of the sun gear to apply resistance to rotation of the sun gear. In addition, a traction pin, a tractor, a trailer, and a truck are also provided.

摘要： A system for estimating a hitch angle includes a control module with memory for storing programmatic control logic, a processor for executing the control logic, and one or more input/output (I/O) ports. Wheel speed sensors on a trailer communicate with the processor via the I/O ports. A trailering application defines a portion of the control logic and has at least first, and second control logics. The first control logic estimates the hitch angle from a first term, a second term and physical parameters of the vehicle and trailer. The second control logic provides the estimated hitch angle to one or more of a driver and to on-board control systems of the vehicle and trailer.

摘要： An oscillation brake system and method is disclosed for a vehicle having front and rear vehicle sections coupled with an oscillation joint that allows rotation about an oscillation axis. The system includes front and rear brake sections rigidly coupled to the front and rear vehicle sections, respectively. The rear vehicle section has multiple degrees of freedom of movement relative to front vehicle section. When the oscillation brake is activated the front brake section engages the rear brake section to increase resistance against or prevent rotation about the oscillation axis. The system can also include sensors, and a controller that activates the system based on the sensor readings. The sensors can include accelerometers, pressure, position, speed or other sensors. The oscillation brake can include a hub splined to separator plates and a housing splined to friction plates, where the oscillation brake is activated to force the separator and friction plates together.

摘要： The present disclosure provides a hitch suspension system that reduces a transfer of energy (e.g., provides a smoother ride) between two bodies hitched together, such as between a towing vehicle and a towed vehicle/trailer. In an embodiment, the suspension system includes a hydraulic cylinder with an extendable rod in fluid communication with a fluid pump. A control valve is fluidly coupled between the hydraulic cylinder and the fluid pump and is configured to adjust an extension length of the rod. Additionally, a variable orifice that adjusts resistance to extension and retraction of the rod is fluidly coupled between the hydraulic cylinder and the control valve. A first fixed restrictive element is fluidly coupled in series with the variable orifice to dissipate energy ad the rod extends and a second fixed restrictive element is fluidly coupled in series with the variable orifice to dissipate energy as the rod retracts.

摘要： An accessory for trailer hitch systems having components for equalizing loads and reducing trailer sway. The accessory includes a jacket for attaching to a bracket that supports a load equalizing spring bar. The bracket may include a lateral extending portion for supporting the spring bar. The jacket may include a socket for receiving the lateral extending portion of the bracket, such that the jacket may be removably installed on the bracket. The jacket may include a contact surface for contacting the spring bar. The contact surface may include a different coefficient of friction or a different shape, as compared to the lateral extending portion of the bracket, such that movement of the spring bar with respect to the bracket may be altered as compared to conditions in which the spring bar is supported on the bracket without the jacket.

摘要： The invention relates to an improved hitch coupling assembly which dampens the hunting movements of a road trailer being towed by a motor vehicle and which is intended for a vehicle combination comprising a motor vehicle and a trailer. More specifically, the inventive hitch coupling assembly (4) comprises: (i) a first pivot coupling (12) for the hunting movements, consisting of a pivoting device which dampens the hunting movements (40) of the trailer and which is housed in a closed space such that it is sheltered from the ingress of pollutant materials; and (ii) a second coupling (21) for the rolling and pitching movements, which is used for the play-free transmission of the hunting movements to the first coupling, the axis of the hunting movements being thus decoupled from the rolling and pitching movements. The damping device preferably comprises a stack of friction disks (41) which are alternately solidly connected to the vehicle or the trailer and which pivot in relation to one another under the effect of the hunting movements.
