Abstract
The guide system, for a guided road vehicle, having a front directional assembly formed of two pivoting guide arms (2) and (3) which are coupled as well as vertically constrained, each equipped with an inclined guide wheel (12, 13) engaging at least one guide rail on the ground (16). At the rear, a follower-limiter module (47) designed to limit lateral clearance by the axle to a maximum value, in the form of a device following the guide rail, is pivotably attached to the axle (8) and laterally displaceable to a limited extent. The front directional unit and the follower-limiter module (47) are laterally connected to either side of the axle through a lateral temporary immobilizing device (43, 44) which controls change of position.
Claims17
A guide system connected to an axle of a vehicle, comprising, a guide assembly with two inclined guidance wheels displaceable along at least one ground guide rail provided in the ground;
- wherein the guide assembly is a directional unit (1) formed of two separate adjacent arms (2 and 3) which are each separately pivotable about an axis (7) extending transverse of the vehicle;
- each of the two separate adjacent arms (2 and 3) supports an inclined guidance wheel (12, 13 or 14, 15) adjacent a free extremity thereof which is engageable for movement along said at least one ground guide rail;
- a coupling restraint acts on the two separate adjacent arms (2 and 3) and a contact shoe biases both of the two separate adjacent arms (2 and 3) toward engagement with the at least one ground guide rail to facilitate constant engagement therewith during use of the guide system.
A guide system connected to axle of vehicle, comprising;
- a guide assembly with two inclined guidance wheels displaceable along at least one ground guide rail provided in the ground;
- wherein the guide assembly is a directional unit (1) formed of two separate adjacent arms (2 and 3) which are each separately pivotable about an axis (7) extending transverse of the vehicle;
- each of the two separate adjacent arms (2 and 3) supports an inclined guidance wheel (12, 13 or 14, 15) adjacent a free extremity thereof which is engageable for movement along said at least one ground guide rail;
- a coupling restraint acts on the two separate adjacent arms (2 and 3) and a contact shoe biases both of the two separate adjacent arms (2 and 3) toward engagement with the at least one ground guide rail to facilitate constant engagement therewith during use of the guide system;
- and
- the guide system further includes a lateral clearance follower-limiter module (47) provided with a pair of inclined guidance wheels, the lateral clearance follower-limiter module (47) is provided behind and is pivotably attached to the axle (8) of the vehicle, and the lateral clearance follower-limiter module (47) is laterally displaceable, along an arc CD centered on a mid-point A of the two contact points of the pair of inclined guidance wheels of the guide assembly, to an extent permitted by deformable articulations (61).
A guide system connected to an axle of vehicle, comprising;
- a guide assembly with two inclined guidance wheels displacable along at least one ground guide rail provided in the ground;
- wherein the guide assembly is a directional unit (1) formed of two separate adjacent arms (2 and 3) which are each separately pivotable about an axis (7) extending transverse of the vehicle;
- each of the two separate adjacent arms (2 and 3) supports an inclined guidance wheel (12, 13 or 14, 15) adjacent a free extremity thereof which is engageable for movement along said at least one ground guide rail;
- a coupling restraint acts on the two separate adjacent arms (2 and 3) and a contact shoe biases both of the two separate adjacent arms (2 and 3) toward engagement with the at least one ground guide rail to facilitate constant engagement therewith during use of the guide system;
- and
- the guide system further includes an identical guidance assembly which is laterally movable by lateral displacement along the pivot axle, the identical guidance assembly is provided behind the axle and is provided with a pair of inclined guidance wheels, an immobilization device is coupled to the identical guidance assembly, and when the immobilization device is inactive, the identical guidance assembly serves as a lateral clearance follower-limiter module.
