摘要： An elongated trailer has a frame with longitudinally extending frame members connected by front and rear cross frame members, and a pair of wheels are pivotally connected to opposite ends of each of the front and rear cross frame members. A steering system includes a front steering crank member connected to a tow bar and supported by the front cross frame member for pivotal movement on a vertical axis, and a rear steering crank member is supported by the rear cross frame member for pivotal movement on a vertical axis. A set of tie rods pivotally connect the front and rear crank members to the corresponding front and rear wheels. An elongated link member or rod connects the front and rear crank members and extends longitudinally of the frame substantially above the bottom surfaces of the frame members to protect the steering system from projecting objects on the ground.

摘要： A vehicle has first and second rear drive wheels that are driven independently of each other and a pair of front wheels that freely rotate about a vertical axis wherein the rear drive wheels and the front wheels are rotatably mounted to a frame. A locking mechanism is operatively connected to the pair of front wheels to restrain the rotation of the front wheels about the vertical axis and maintain the pair of front wheels in a forward position while the operator engages the locking mechanism. When the operator releases the locking mechanism, the locking mechanism is removed from the pair of front wheels and the pair of front wheels are free to rotate about the vertical axis.

摘要： A steering apparatus for a zero-turn radius vehicle using a steering mechanism coupled to a first set of wheel assemblies by a plurality of cables. User input to the steering mechanism causes the cables to turn the first set of wheel assemblies about a vertical axis. Specifically, the cables link the steering mechanism to cam mechanisms that are attached to each wheel assembly. The design of the cam mechanism, which preferably includes two cams of varying radii, enables the two wheel assemblies to rotate about their vertical axes at varied degrees of rotation and greater than ninety degrees from the forward facing position, thereby resulting in zero-turn radius capability.

摘要： A trailer having a frame extending along a longitudinal axis and having a front end and a rear end, a steering linkage coupled to the frame, a pair of front wheel assemblies coupled to the front end of the frame, and a pair of rear wheel assemblies coupled to the rear end of the frame. Each wheel assembly includes a wheel carrier having a pivot member pivotally coupled to the frame along a steering axis, the wheel carrier being coupled to the steering linkage so that actuation of the steering linkage pivots the wheel carrier about the steering axis, and a wheel rotatably coupled to the wheel carrier along a wheel axis. The wheel axis is oriented approximately perpendicular to the steering axis, and the wheel axis is offset from the steering axis.

摘要： A steering system for steering a plurality of conveyor vehicles connected together in the form of a train. The vehicle has a first pair of wheels which can be steered by an operator as the train moves. There are further pairs of steerable wheels connected to the second and subsequent vehicles in the train and supporting same. There are hydraulic cylinders for steering each of the pairs of steerable wheels on the second and subsequent vehicles and a control mechanism for controlling these cylinders in order to set the steering angle of each further pair. This control mechanism includes means for determining the current steering angle of the first pair of wheels and generating an electrical signal indicative thereof and means for storing a series of these electrical signals as the train is travelling. Further means determine the amount of time the wheels in the train have been travelling and there is a calculator for determining the location of each of the further pairs of wheels on the basis of the determined travel time. A second electrical signal is generated for each further pairs of wheels in order to control its respective hydraulic cylinder and thereby set the steering angle of each pair at the same steering angle that the first pair of wheels had when they were at that location.

摘要： An axle arrangement for a vehicular trailer is provided. This arrangement includes at least one rigid guide axle and therebehind a follower steering axle having wheel and tire assemblies that are connected to a rigid axle member via control levers and are interconnected via a tie bar. The axle members of the guide axle and of the follower steering axle are supported via connecting springs on brackets and pneumatic cushioning bellows that are secured to the chassis of the trailer. So that the follower steering axle can have the same connection dimension relative to the longitudinal members of the trailer as does the rigid guide axle, the connecting springs of the follower steering axle, between the forward brackets and the axle member, are bent inwardly toward the center of the axle member by an amount that is equal at most to half the difference between a center to center distance of the connecting springs of the rigid guide axle and the follower steering axle.

摘要： In mobile and steerable lifting and setting-down apparatus for large transportable receptacles, in order to ensure steerability of the apparatus not only in pulling operation, but also in backward pushing operation, steering arms are attached to be movable up and down to the wheel cradles carrying the running wheels, the steering arms being articulated by their free ends to a steering rod which is mounted to be movable rotationally about its axis. A central shaft is coupled to the steering rod to be relatively movable in the direction of the axis of the shaft. The central shaft is pivoted by its inner end by means of a pintle to a connecting piece which in turn is mounted on the large receptacle to be swingable about an axis parallel to the base of the receptacle. The articulation point for the central shaft on the connecting piece which is formed by the pintle is located laterally in alignment with the pivots of the two adjacent wheel cradles. The steering of the running wheels takes place through the central shaft by way of the steering rod and steering arms while in pulling or backward pushing operation the corresponding forces act on the large receptacle by way of the central shaft, the connecting piece and the connecting posts.
