Abstract
A vehicle steering system includes a gear rack supported in a fixed position, a pinion gear in meshing engagement with the gear rack, a steering subsystem supporting the pinion gear and moveable in a translational manner relative to the gear rack and at least one steering arm coupled to steering subsystem and configured to steer a motive member in response to movement of the steering subsystem. The vehicle steering system is configured to remain substantially within a framework of the vehicle while steering one or more motive members of the vehicle.
Claims19
A vehicle steering system comprising:
- a gear rack configured to remain in a fixed position relative to a vehicle chassis;
- a pinion gear in meshing engagement with the gear rack;
- a steering subsystem supporting the pinion gear and moveable in a translational manner relative to the gear rack;
- and
- at least one steering arm coupled to the steering subsystem and configured to steer a motive member in response to movement of the steering subsystem.
A vehicle steering system comprising:
- a gear rack supported in a fixed position;
- a pinion gear in meshing engagement with the gear rack;
- a steering subsystem supporting the pinion gear and moveable in a translational manner relative to the gear rack, the steering subsystem including a housing and a steering arm base;
- and
- at least one steering arm coupled to the steering subsystem and configured to steer a motive member in response to movement of the steering subsystem,
- wherein the housing includes a first aperture configured to receive the pinion gear.
A vehicle comprising:
- a chassis including at least one motive member and a hull, the hull including a first side wall and a second side wall;
- a vehicle steering system, for steering the motive member, comprising:
- a steering subsystem including a housing;
- a member received by the housing, the member supporting a gear rack having a plurality of teeth, the member and the gear rack being secured in a fixed position relative to the chassis between the first and second side walls;
- and
- a pinion supported by the housing and having a gear portion in meshing engagement with the plurality of teeth of the gear rack;
- wherein the steering subsystem moves in a translatable manner relative to the member upon rotation of the pinion.
