Abstract: A tensioning device for attachment to a vehicle suspension system reduces play at ends of a pan hard bar (track bar) of the vehicle suspension system, remedying instabilities that can occur in vehicle suspensions. The device can include a bracket clamped to the pan hard bar at a point between the ends of the pan hard bar, or may be otherwise mounted to a bracket formed on the pan hard bar in OEM installations. The other end of the device is secured to the frame or the axle of the vehicle, generally near an end of the pan hard bar. The device is pre-tensioned to apply force at the ends of the pan hard bar, and includes a damping plunger to also damp forces that vibrate the ends of the pan hard bar, further loosening attachments. The tension is field-adjustable and may be tuned for various applications.
Abstract: In a four-wheel vehicle with vertically independently movable wheels (2?, 2?, 3?, 3?), diagonally opposite wheels (2?, 2? or 3?, 3?) are connected to one another by respective cables (9, 90) guided over deflection rollers (11 to 15). The traction cable mounting makes it possible to adapt the height of the wheels in the event of equal loading of the individual wheels independently of the terrain.
Abstract: A stabilizer serves for stabilizing a link of a three-point suspension system of an agricultural tractor. The stabilizer has at least one telescope consisting of a tube and a piston held displaceably therein. Said tube and piston are coupled elastically by at least one spring. The piston is designed such that it can be adjusted in length by means of at least one thread. In order to retain the telescope, the stabilizer has at least one pivotably held retaining clip. In a retaining position, said retaining clip engages over an abutment of the piston whereas, in a release position of the retaining clip, the piston can be freely moved. In order to obtain simple handleability of said stabilizer, the abutment is formed by at least one substantially rotationally symmetrical disc. The piston length can therefore be adjusted in or in the vicinity of the retaining position.
Abstract: A GaN-based heterostructure field effect transistor capable of accomplishing higher output, higher breakdown voltage, higher speed, higher frequency, and the like. A heterostructure field effect transistor including a channel layer (4) of GaN and a barrier layer (6) of AlGaN, wherein the surface of a transistor element has an insulating film (10).

Abstract: A stabilizing apparatus and method that replaces the existing shock absorber of a road vehicle that works to resist the initiation of body roll during cornering. It seeks to counter act the forces being generated by the vehicle suspension springs that exacerbate the rollover propensity of vehicles during certain steering maneuvers.
