Ultra narrow enclosed motor vehicles

Claim 2

A road vehicle, comprising a chassis structure, suspension means including road running wheels mounted to the chassis structure, means for enabling steerable displacement of at least one of the road wheels with respect to the other wheels and the chassis structure, means for mounting a prime mover and associated transmission on the chassis structure for transmitting drive to at least one of the road wheels, a body for encompassing at least one person mounted upon the chassis structure and symmetrically positioned with respect to a perpendicular medial plane of the chassis structure, the body being tiltable relative to the medial plan and to at least a part of the chassis structure, and user actuatable means for selectively tilting the body structure comprising: (a) means for producing relative tilt between the body structure and a portion of the chassis structure; (b) a right foot operable pedal mounted to the body structure; (c) a left foot operable pedal mounted to the body structure; (d) a control connection between the right pedal and the tilt producing means such that operation of the right pedal produces a tilt of the body structure towards the right side of the medial plane; and (e) a control connection between the left pedal and the tilt producing means such that operation of the left pedal produces a tilt of the body structure towards the left side of the medial plane.

Claim 3

A road vehicle as claimed in claim 1 wherein the two control connections include means for servo-assisting the operation of the associated pedal operation in producing a desired tilt of the body structure.

Claim 4

A road vehicle as claim in claim 1 wherein the means for producing relative tilt includes a hydraulic piston and cylinder arrangement connected between the body structure and the chassis structure each of said control connections includes a hydraulic ram hydraulically coupled with the piston and cylinder arrangement by way of fluid conduits, each hydraulic ram being additionally connected so as to be operated on depression of the associated pedal to thereby cause corresponding operation of the piston and cylinder arrangement and produce the desired tilt of the body structure.

Claim 5

A road vehicle comprising (a) a chassis structure including a first section, a second section and a pivoted connection between the two sections defining an axis extending in the longitudinal direction of the chassis structure and lying in a medial plane thereof; (b) suspension means including a road running wheel arrangement mounted to each said sections of the chassis structure; (c) a steering means for enabling steerable displacement of at least one of the road running wheel arrangements with respect to the chassis structure; (d) means for mounting a prime mover to the first section of the chassis structure; (e) means for transmitting drive from the prime mover to at least a selected one of the road running wheel arrangements; (f) a body structure for encompassing at least one person mounted upon the second section of the chassis structure so as to be symmetrically positioned with respect to the medial plane of the chassis structure and so as to be bodily tiltable with the second chassis section relative to the first chassis section; (g) user actuatable means for producing relative tilt between the body structure and the first chassis section, the user actuatable means including, (i) first and second user operable foot pedals mounted with respect to the body structure and second chassis section so as to be located one to the left side of the medial plane and one to the right side of the medial plane; (ii) means for producing relative tilt of the first chassis section relative to the second chassis section, (iii) an operational control connection between the first pedal and the means for producing tilt, and (iv) an operational control connection between the second pedal and the means for producing tilt, (v) each said control connection being such that operation of its associated foot pedal causes the second chassis section to tilt relative to the first chassis section in a direction towards the same side of the medial plane as the operated foot pedal.

Claim 6

A road vehicle comprising (a) a chassis structure including a first section, a second section and a pivoted connection between the two sections defining an axis extending in the longitudinal direction of the chassis structure and lying in a medial plane thereof; (b) suspension means including a road running wheel arrangement mounted to each said sections of the chassis structure; (c) a steering means for enabling steerable displacement of at least one of the road running wheel arrangements with respect to the chassis structure; (d) means for mounting a prime mover to the first section of the chassis structure; (e) means for transmitting drive from the prime mover to at least a selected one of the road running wheel arrangements; (f) a body structure for encompassing at least one person mounted upon the second section of the chassis structure so as to be symmetrically positioned with respect to the medial plane of the chassis structure and so as to be bodily tiltable with the second chassis section relative to the first chassis section; (g) user actuatable means for producing relative tilt between the body structure and the first chassis section, the user actuatable means including, (i) first and second user operable foot pedals mounted with respect to the body structure and second chassis section so as to be located one to the left side of the medial plane and one to the right side of the medial plane; (ii) means for producing relative tilt of the first chassis section relative to the second chassis section, (iii) an operational control connection between the first pedal and the means for producing tilt, and (iv) an operational control connection between the second pedal and the means for producing tilt, (v) each said control connection being such that operation of its associated foot pedal causes the second chassis section to tilt relative to the first chassis section in a direction towards the same side of the medial plane as the operated foot pedal.
