摘要： A draft control system for a tractor has a load sensing apparatus comprising a beam supported in fulcrum bearings responsive to loads between the tractor and an attached implement. The fulcrum point in the bearing is automatically changed as the load increases so as to reduce the response rate to changes in load. The fulcrum point is further adjustable by rotation of the bearings to vary the response or sensitivity of the system and the effective fulcrum point for compression loads can be located at a different point than the effective fulcrum point for tension loads.

摘要： One variation of a method includes, during a first time period: detecting a direction of motion of a trailer; detecting a first force applied to a kingpin; detecting an incline angle of the trailer; calculating a first target preload force opposite the direction of motion and inversely proportional to the incline angle; and in response to the first force falling below the first target preload force, triggering a motor to increase torque output opposite the direction of motion. The method further includes, during a second time period: detecting a second force applied to the kingpin; detecting a decline angle of the trailer; calculating a second target preload force opposite the direction of motion and inversely proportional to the decline angle; and in response to the second force falling below the second target preload force, triggering the motor to increase torque output opposite the direction of motion.

摘要： Measuring devices and methods for ascertaining an operating parameter at a shaft are disclosed. The shaft may be supported by at least one bearing. In one example, the measuring device includes at least one first sensor element configured to detect an absolute angle of the shaft and at least one second sensor element configured to detect a change in a distance of the shaft from the at least one second sensor element. A computing device may be configured to calculate one or more operating parameters at the shaft from the absolute angle of the shaft and the change in the distance.

摘要： A force sensor is suitable for an electrohydraulic hitch control system of an agricultural tractor. The force sensor has an outer cylindrical part with a bore and a measuring rod fixed on one side in the bore. A central section of the cylindrical part is provided as force introduction section. Two outer sections of the cylinder part are removed equally far axially from the center of the force introduction section and are provided as abutment sections. The measuring rod is clamped in an area of the force introduction section.

摘要： A trailer for a vehicle with a high voltage traction-battery. The trailer may be a self-propelled trailer to substantially match vehicle dynamics and minimize impact on the vehicle. Alternatively, the trailer may push the vehicle to simulate hill descent, or drag on the vehicle to simulate hill ascent. The trailer may provide power for the vehicle. The trailer may provide current to a vehicle electric machine. The trailer may also provide current to recharge a vehicle traction-battery. The trailer may also recharge its own traction-battery.

摘要： A ball mount for measuring tongue weight of a trailer is disclosed. The ball mount can include a ball portion having a hitch ball configured to couple with a tongue of a trailer. The ball mount can also include a hitch portion for interfacing with a hitch receiver associated with a vehicle. In addition, the ball mount can include a load measurement device associated with the ball portion to determine a magnitude of a downward force on the hitch ball. The load measurement device can include a reservoir having a fluid and a piston disposed therein, and a pressure sensor in fluid communication with the reservoir. The hitch ball can be configured to exert a force on the piston, thereby affecting a pressure of the fluid in response to the downward force on the hitch ball.
