Abstract

A coupling assembly is coupling a steering mechanism to a steering axle of a vehicle. The coupling assembly comprises subassemblies, one mounted to the chassis and the other to the bogie; and racks extending side by side, that couple the subassemblies. One rack is coupled to steering mechanism and the one subassemblies is coupled to the steering axle. The coupling assembly operates such that when the steering member moves relative to the first subassembly, it exerts the racks to move relative to each other, resulting in the second subassembly steering the steering axle. However, when the bogie moves, the second subassembly moves without the elongated members moving relative to each other.

IPC Classes  ?

• B62D 13/02 - Steering specially adapted for trailers for centrally-pivoted axles
• B60G 15/12 - Resilient suspensions characterised by arrangement, location, or type of combined spring and vibration- damper, e.g. telescopic type having fluid spring and fluid damper
• B62D 13/04 - Steering specially adapted for trailers for individually-pivoted wheels

Abstract

A steering wheel system for a semi-trailer is described. The system uses a retractable encoded system releasably connected to a kingpin, a mechanical steer driving system translating the rotation of the kingpin to a hydraulic system, and a non-circular cogged system driven by the hydraulic system adapted to steer the wheels. A hydraulic generator system powered by the rotation of the wheels is used to decrease the electric energy required by the hydraulic system. Other improvements are also present to increase security, decrease weight and improve time expectancy of the components.

IPC Classes  ?

• B62D 13/02 - Steering specially adapted for trailers for centrally-pivoted axles
• B62D 9/00 - Steering deflectable wheels not otherwise provided for
• B62D 53/08 - Fifth-wheel traction couplings

Abstract

A steering assembly for steering a vehicle. The steering assembly comprises a first steering knuckle having a first wheel rotatably mounted thereto, a first swing mechanism for enabling displacement of the first steering knuckle along a first arced path and a first guiding mechanism for pivoting the first steering knuckle when the first steering knuckle is displaced along the first arced path in order to maintain the first wheel oriented tangentially relative to the first arced path. The first arced path is concave relative to a central longitudinal axis of the vehicle and spaced from the first frame member, away from a central longitudinal axis of the vehicle, by a distance sufficient to prevent the first wheel from contacting the first frame member when the first steering knuckle is pivoted. There is further provided a method of operating the steering assembly.
