    摘要: A steering system for steering a heavy haul trailer dolly comprising a turntable mounted on the dolly for connecting to another trailer unit. The dolly comprising a main frame, a wheel group mounted to the main frame, and a pivot frame mounted to the main frame between the turntable and the wheel group. A counter-steering linkage connects the pivot frame and the turntable. Hydraulic cylinders connect the pivot frame and the wheel group. To automatically steer the dolly, the hydraulic cylinders are locked in length. Rotation of the turntable in one direction causes the pivot frame and the wheel group to rotate in the opposite direction. To steer the dolly directly, the hydraulic cylinders are operated to extend and retract, pushing and pulling against the pivot frame and turntable to rotate the wheel group.

    摘要: The invention relates to a method for assisting a driver in maneuvering a motor-vehicle combination (1) comprising, as vehicles, at least one tractor motor vehicle (2) and at least two trailers (3a, 3b) coupled thereto, wherein a target articulation angle (γ2) at least between two of the vehicles (3a, 3b) is externally specified and is adjusted by means of at least one steering actuator (5a, 5b) of at least one of the vehicles (2). The method comprises at least the following steps: a) dividing the motor-vehicle combination (1) into at least two sub-combinations (1a, 1b) in such a way that adjacent vehicles (2, 3a, 3b) form a sub-combination (1a, 1b) in pairs, in which sub-combination a first vehicle is used as a trailer unit (3a, 3b) and a second vehicle is used as a tractor vehicle unit (2, 3a), at least virtually; b) repeatedly determining a target angle (α, γ1, γ2) for a number of consecutive sub-combinations (1a, 1b) from a specified target articulation angle (γ1, γ2) between the tractor vehicle unit (2, 3a) and the trailer unit (3a, 3b), beginning with the sub-combination (1a) whose target articulation angle (γ2) was specified externally, wherein: —the determined target angle is adjusted as a target steering angle (α) for the tractor vehicle unit (2) of the sub-combination (1b) by means of the at least one steering actuator (5a, 5b) of the associated vehicle (2) if the tractor vehicle unit (2) has the at least one steering actuator (5a, 5b), or —the determined target angle is specified as the target articulation angle (γ1) for the next sub-combination (1b).

    摘要: A vehicle, a single-wheelset/double-wheelset trackless train and a tracking and steering control method therefor are provided in the invention. The method includes the following steps. During traveling of the vehicle, steering information of the vehicle is continually collected by the controller. Information about a guiding front wheel turning angle, a controlled rear wheel turning angle, a vehicle body position angle, an included angle between vehicle bodies, and a vehicle travel time and speed is collected; an interval for data collection is determined according to a distance between a guiding front wheel and a controlled rear wheel; and when the controlled rear wheel travels to a certain point near a front wheel travel track, the controlled rear wheel is controlled to travel in a travel direction same as that when the front wheel travels to the point. According to the rear wheel tracking and steering control method, the objective that a controlled rear wheel operates in a manner of highly approaching a guiding front wheel track can be achieved; and the higher a data collection frequency is, the higher a track fitting degree of the front wheel and the rear wheel is.

    摘要: A motor-assisted joint system is provided to improve maneuverability and safety of an articulated bus. The motor-assisted joint system is enabled when the articulated bus is operated in an active damping mode. An articulated joint with a flat motor is used. According to the velocity of the articulated bus, a highly sensitive damping force is calculated and an opposing force is generated to balance the inertia of the articulated bus when an oversteering event or a tire slip event occurs. Consequently, the driving performance of the articulated bus in various aspects is enhanced.

    摘要: A dual lane, multi-axle transport vehicle for moving heavy loads includes a forward module mounted on a plurality of axles and a rearward module mounted on a plurality of axles. The forward module is mechanically connected to the rearward module for providing a dual lane transport body. The forward module and the rearward module of the transport body each have a single central spine wherein the axles of both the forward module and the rearward module are each attached to the corresponding single central spine. The axles of both the forward module and the rearward module have an axle spacing of at least six feet. A hydraulic suspension is provided for dynamically stabilizing the axles for reducing axle yaw. An axle steering system having a plurality of steering rods controls the position of the axles of both the forward module and the rearward module.

    摘要: A method of controlling the sideways motion of a trailer forming part of a combination vehicle, such as a road train, for road transport of heavy goods. The vehicle has a trailer including a semi-trailer body and a dolly mounted beneath the front of the semi-trailer body. The method includes steering at least some of the wheels on said axle sets relative to the dolly frame such that at high speeds, as the vehicle turns towards one side, steering the dolly wheels to induce the dolly to move towards that side and, at low speeds, as said vehicle turns towards that side, steering the dolly wheels to induce the dolly to move towards the opposite side.
