  • Patent number: 7389998
    Abstract: A vehicle steering system is configured to avoid contact between wheels and wheel housings when the wheels are steered and to enlarge the maximum steering angle. The vehicle steering system has a steering knuckle that supports a wheel for rotation about a wheel axis and a pivotal movement about a steering axis. The steering knuckle is coupled to a first end part of an extension link. A second end part of the extension link is connected to an arm through a control rod. The extension link is pivotally sustained around a steering axis. The arm is connected to a front end of a knuckle arm through a tie rod. When the arm turns, the second end part of the extension link is pulled inside through the control rod, and the steering knuckle situated on rear end of the control rod is pushed outwardly. At the same time, the arm steers the steering knuckle through the tie rod.

  • Publication number: 20080073867
    Abstract: In conventional vehicle cranes it is usually necessary in consideration of current safety regulations to provide at least two separate steering circuits for all steered axles so that, in the event of a failure of one circuit, the vehicle crane can continue to be steered by way of the other. In order to avoid that in accordance with the invention at least one steered rear axle of a vehicle crane (1) is provided with a caster (a) so that at least one axle (11-16), in the event of a steering failure, remains steerable passively by utilising the caster friction. That principle is applied in a similar manner to a module axle (2) which can be mounted to the vehicle crane (1) and which can be required for transporting additional equipment or an additional counterweight which is possibly required.

    Abstract: A control arm includes a connection tube and two mounting eyes respectively attached to opposite ends of the tube. Each mounting eye has a sleeve and a rubber-metal element vulcanized into the sleeve. In a method of making such a control arm, an elongate tubular member is sized to a sleeve blank of a length commensurate with the tube. Parallel thereto, an extruded profile is made with a cross sectional configuration of the sleeve and subsequently sized to the axial height of the sleeve. Rubber-metal elements are vulcanized into the sleeve blanks which together with the tube are then clamped, axially shiftable, in a friction welding machine for subsequently fabricating protruding collars on the sleeves through material removal and joining the end surfaces of the protruding collars with the end surfaces of the tube. While still clamped, the tube and the mounting eyes are calibrated through cold upsetting and the joints are smoothed.

  • Publication number: 20050116434
    Abstract: An integrated steering gear and frame structure is designed to modularize a sub-frame as a suspension system and a steering gear as a steering system. Thus, a separate assembly process for the sub-frame and the steering gear is not required, so that a production process can be simplified and an assembly capability can be improved.

  • Patent number: 6869088
    Abstract: A steering apparatus for a vehicle has: a steering shaft rotatable with a steering force applied from a steering wheel; a cable unit for transmitting a rotational force with an output member and a pair of cable wires; and a speed reducing gear disposed between the steering shaft and the cable unit. The output member makes a rotation in such a manner that the pair of the cable wires are pulled relative to each other. The rotational force is transmitted from the steering shaft to a side having a tire-and-wheel.

  • Patent number: 6796567
    Abstract: A cable-type steering device in which a driving pulley coupled to a first pulley shaft connected to a steering wheel and a follower pulley coupled to a second pulley shaft connected to a steering gear box are connected to each other by operating cables, whereby a steering torque input to the steering wheel is transmitted through the operating cables to the steering gear box. At least one of transmission of a steering torque between the driving pulley and the first pulley shaft and transmission of a steering torque between the follower pulley and the second pulley shaft is carried out through a tapered coupling portion including a tapered surface formed on an outer periphery of at least one of the first and second pulley shafts and a tapered surface formed on an inner periphery of at least one of the driving pulley and the follower pulley.

  • Publication number: 20040155422
    Abstract: A steering triangle (1) is provided for the axle suspension of motor vehicles for the articulated connection of a vehicle axle with a vehicle chassis with two control arms (2, 3). The control arms are connected to each other in a joint housing (6) formed by the control arms (2, 3) together for a rubber-metal bearing (11) for fixing the steering triangle (1) on the vehicle axle. The rubber-metal bearing (11) has a pivot axis (12) provided with a spherical surface and an elastomer body (14), which extends around the pivot axis (12) at least in the area of the spherical surface and which is accommodated in a recess (16) located within the joint housing (6), in which steering triangle two pressing rings (17, 18) are arranged within the recess (16) of the joint housing (6) on the axial outer sides of the elastomer body (14). The pressing rings can be moved toward each other by a tensioning device via the intermediary of stop faces (22) of the joint housing (6).

  • Patent number: 6719311
    Abstract: A steering assembly is provided for steering a pair of vehicle wheels. The assembly includes a tie rod assembly having first and second tie rods. Each of the tie rods has an inboard end and an outboard end. The inboard ends may be coupled to the output member of a steering gear or they may be supported on a movable support member. The outboard ends are coupled to the vehicle wheels and, in particular, to tie rod arms extending from steering knuckles. The inboard ends of the tie rods are positioned forward of the outboard ends of the tie rods relative to the forward direction of vehicle travel when the vehicle wheels are facing forward. As a result, the effective length of the tie rod assembly increases as the turn angle of the vehicle wheels increases thereby reducing toe out of the vehicle wheels and tire wear and allowing sufficient clearance with wheel and brake components including brake drums found in conventional drum brake systems.
