Abstract: A work vehicle includes: a wheel support member configured to support a pair of left and right traveling wheels; a link mechanism configured to support the wheel support member such that the wheel support member can be raised and lowered, the link mechanism being provided spanning between a vehicle body and the wheel support member; a suspension mechanism configured to elastically support the wheel support member, the suspension mechanism being provided spanning between a suspension support portion, which is formed on the vehicle body, and the wheel support member; and a lateral link configured to restrict leftward and rightward movement of the wheel support member, the lateral link being joined to a vehicle body-side support portion, which is formed on the vehicle body, and to a wheel-side support portion, which is formed on the wheel support member, wherein the link mechanism has: an upper link with an front end portion supported so as to be able to pivot up and down around an upper pivot axis by a link sup

Abstract: Vehicle suspension comprising a pair of leaf springs (1) located or locatable on respective opposed side of a vehicle chassis (3) and extending longitudinally thereof, and an anti-roll device (12) which is arranged to extend transversely of the vehicle chassis (3), and means (41, 42, 46) mounting opposed ends (22, 23) of the anti roll device (12) rigidly to respective ones of the pair of opposed leaf springs (1).

Abstract: A suspension deflection system is provided that includes first and second spaced apart supports, an elastomeric body positioned at least partially in the region between the first and second supports, and a suspension engaging projection extending from the second support in a direction away from the first support. The elastomeric body includes first and second opposed body end surfaces coupled respectively to the first and second supports, and first and second body side surfaces extending between the body end surfaces. The body side surfaces are closer to one another at a location intermediate to the body end surfaces than at the first and second supports. The system conveniently and securely couples a suspension member of a vehicle engaged by the projection to a frame of the vehicle.

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 front suspension assembly is mountable to a longitudinally extending frame of a truck and includes a pair leaf springs mounted on opposite sides of the frame of the truck at the front, such leaf springs extending backwardly from the front of the truck, a pair of vertically disposed guides extending downwardly from the frame and providing an aperture though which a leaf spring runs, a pair of shock absorbers extending downwardly from the frame of the truck to below the leaf springs and supporting the leaf springs, and a pair of air cushion assemblies each having a bottom attached to the top of the back of one of the leaf springs and a top attached to the frame of the truck.

Abstract: In order to limit rolling movements of the vehicle, spring arms are formed on those ends of the leaf spring, arranged transversely to the vehicle, on which the wheel carriers are articulated, said spring arms being connected in a force-transmitting manner to the transverse leaf spring. The spring arms point toward the longitudinal mid-plane of the vehicle and run at an acute angle to the transverse leaf spring. Since the spring designed in this way is a universally available structural part (the spring arms running at an angle may also be produced separately and then be connected non-positively to the transverse leaf spring), the two wheels are connected to one another directly and the triangular shape formed by the spring arms running at an angle gives rise to a function similar to that of a transverse link.
