Abstract: Rotor flight vehicle includes a first rotor, a power unit, a transmission from the power unit to the first rotor, wherein said transmission comprises at least one belt, a group of rotational axes, at least one power output axle connected to the power unit and at least one rotor axle connected to said first rotor, the belt is applied to the power output axle, the power output axle is concentric with a rotational axis, the belt transmits power to the rotor axle, the rotor axle is concentric with a rotational axis, wherein consecutive rotational axes of the group of rotational axes extend in a relation to each other such that the angle between them is in the range of 80-100 degrees, wherein the belt has a maximal torsion of 80-100 degrees, in the belt's transition between two respective consecutive rotational axes of the group of rotational axes.
Abstract: A rear suspension of a three-wheeled car with two front wheels and one rear wheel installed in the car body frame may include a pair of roll links that may be connected to the front wheels and twists as the car turns, and a roll connector that pivots around a shaft as the roll links twist, and a knuckle assembly, which may be joined to a rear wheel, installed in the rear end of the car body frame, and connected to a roll connector so that it turns left and right as the roll connector turns, wherein the knuckle assembly turns in the same direction the front wheels turn.
Abstract: A vehicle has a chassis (11) and at least one axle (12, 13) suspended from the chassis for vertical and roll movement relative to the chassis. The axle is mounted on the chassis via a first pivotal mounting means in the form of an upper pair of arms (12a, 13a) which is pivoted on the chassis for vertical pivoting movement relative thereto and which carry an axle support (15, 16) on which the axle (12, 13) is free to pivot in the roll mode. A first damping means (19) acts between the chassis (11) and the first pivotal mounting means (12a, 13a) to control vertical movement of the axle relative to the chassis, and a second damping means acts between the first pivotal mounting means (12a, 13a) and the axle (12, 13) to provide independent control of the roll movement of the axle relative to the chassis. A second lower pair of pivoting arms (12b, 13b) also connect the axle (12, 13) to the chassis to control fore and aft movement of the axle relative to the chassis.
Abstract: A rear suspension of a three-wheeled car with two front wheels and one rear wheel installed in the car body frame may include a pair of roll links that may be connected to the front wheels and twists as the car turns, and a roll connector that pivots around a shaft as the roll links twist, and a knuckle assembly, which may be joined to a rear wheel, installed in the rear end of the car body frame, and connected to a roll connector so that it turns left and right as the roll connector turns, wherein the knuckle assembly turns in the same direction the front wheels turn.
Abstract: A vehicle steering means with a first front ground-engaging steerable wheel located in the front center of the vehicle; second and third front ground-engaging wheels located either side of the first front ground-engaging wheel with means for adjusting the steer angle and the height depending on the steer angle of the first front ground-engaging wheel. When the first front ground-engaging wheel has a straight-ahead steer angle, the second and third wheels are also straight-ahead and all three front ground-engaging wheels are in contact with the ground; and when the steer angle of the first front ground-engaging wheel is turned, the steer angle of the front ground-engaging wheel on the outside of said curve is turned at least partly towards the steer angle of the first front ground-engaging wheel, the steer angle of the front ground-engaging wheel on the inside of said curve is not substantially turned towards the steer angle of the first front ground-engaging wheel.

Abstract: Process for fabricating an axle that includes a cross-member and arms which are assembled to extremities of the cross-member, wherein the process includes forming a cross-member, forming at least one arm, arranging the cross-member and the at least one arm in a fastening position, and fastening together in a rigid manner the cross-member and the at least one arm using a magneto-forming process. Wherein the fastening occurs while the cross-member and the at least one arm are in the fastening position and at least one of the cross-member and the at least one arm include at least one metallic material. This abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: An all-wheel drive vehicle with two steered vehicle axles. Each having a main steering cylinder with piston rods actively connected with the wheels. The main steering cylinders each have first and second chambers (30, 31) delimited by at least one piston element (34, 35) which moves longitudinally in the cylinder and is connected to the piston rod (28), such that adjusting pressure in the cylinder with an electric control unit, biases the piston elements and the piston rods to achieve specified wheel steering angles. Furthermore, a third chamber (32), which can be pressurized, is provided between a first and a second piston element (34, 35) of a main steering cylinder (26), which respectively delimit the first and second chamber (30, 31). The piston rods are sectioned, such that a first section is connected to the first piston element and a second section is connected to the second piston element.
Abstract: A method and apparatus for long vehicles to make sharp turns on city streets without running up on the curb. The back wheels of the vehicle are steered with the aid of a guide control wheel so that when the semi or truck is making a sharp turn, the rear wheels continue straight down the street to the intersection and then turn, even though the semi and the front of the trailer have already turned in a normal manner.
