Turnable Axle (e.g., Fifth-wheel Or Swinging Axle) Patents (Class 280/137.5)
  • Patent number: 8857551
    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.

  • Patent number: 8801012
    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.

  • Patent number: 8172014
    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.

  • Publication number: 20080001380
    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.

  • Patent number: 6604753
    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.
