Abstract
Abstract This invention relates to a motor vehicle with a rhomboidal or diamond configuration of road wheels, with a front steerable wheel, two driven side wheels and a free-wheeling rear wheel with a non-steering axis. For good stability the ratio of the distance from the centre of gravity of the vehicle of the rear and side wheels is between 1.5 and 3, and the ratio between the inter-axis distance of the front and side wheels and the distance between said centre of gravity and the front wheel is between 1.225 and 1.66.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
67 words
A motor vehicle of the type having four road wheels arranged in a rhomboidal disposition comprising a steerable front wheel, two driven side wheels having a common axis and a rear wheel, said front and side wheels only having braking means associated therewith and said rear wheel being freely rotatable with its axis of rotation disposed parallel to the axis of said driven wheels at all times.
Claim 2
Dependent Claim
67 words
A motor vehicle of the type having four road wheels arranged in a rhomboidal disposition comprising a steerable front wheel, two driven side wheels having a common axis and a rear wheel, said front and side wheels only having braking means associated therewith and said rear wheel being freely rotatable with its axis of rotation disposed parallel to the axis of said driven wheels at all times.
Claim 3
Dependent Claim
93 words
A motor vehicle as set forth in claim 1 wherein the ratio of the distance from the center of gravity of the vehicle to the axis of the rear wheel to the distance from the center of gravity of the vehicle to the common axis of said driven wheels is between 1.5 and 3 while the ratio of the distance from the front wheel axis to the common axis of the driven wheels to the distance between the axis of the front wheel and the center of gravity is between 1.225 and 1.66.
Claim 4
Dependent Claim
59 words
A motor vehicle as set forth in claim 2 wherein the distribution of the load upon the wheels is so chosen that, under standard conditions, about 10 percent of the load bears upon the rear wheel and about 25 percent of the load bears upon the front wheel and the remainder of the load bears upon the driven wheels.
Claim 5
Dependent Claim
44 words
A motor vehicle as set forth in claim 1 further including a motor propulsion system disposed between the axis of the driven wheels and the rear wheel, said system including an engine placed crossways in relation to the longitudinal axis of the motor vehicle.
