Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
An aerodynamic body for mounting beneath the undercarriage of a vehicle and in front of the transverse axle which depends from the undercarriage, the axle adapted to carry road running wheels, said body having an effective angle of attack in relation to the direction of travel of the undercarrige and comprising a wind deflection membrane with an aerodynamic striking surface generally concavely curved downward and rearwardly from an upper front portion to a lower rearward portion, the rearward portion being located at an elevation near the centre line of the transverse axle, the upper portion carried by the undercarrige in advance of both the transverse axle and rearward lower portion such that wind striking the striking surface is deflected primarily downward toward the road and hence around the transverse axle as the vehicle moves into the wind.
Claim 2
Dependent Claim
137 words
An aerodynamic body for mounting beneath the undercarriage of a vehicle and in front of the transverse axle which depends from the undercarriage, the axle adapted to carry road running wheels, said body having an effective angle of attack in relation to the direction of travel of the undercarrige and comprising a wind deflection membrane with an aerodynamic striking surface generally concavely curved downward and rearwardly from an upper front portion to a lower rearward portion, the rearward portion being located at an elevation near the centre line of the transverse axle, the upper portion carried by the undercarrige in advance of both the transverse axle and rearward lower portion such that wind striking the striking surface is deflected primarily downward toward the road and hence around the transverse axle as the vehicle moves into the wind.
Claim 3
Dependent Claim
18 words
The aerodynamic deflection as claimed in claim 1 wherein the wind deflection membrane is a rigid sheet surface.
Claim 4
Dependent Claim
26 words
The aerodynamic deflector as claimed in claim 1 where in the lower trailing edge is at an elevation at the centre line of the transverse axle.
Claim 5
Dependent Claim
34 words
The aerodynamic deflector as claimed in claim 1 wherein the deflector is located with the lower trailing edge in advance of the transverse axle by at least the diameter of the road running wheels.
Claim 6
Dependent Claim
29 words
The aerodynamic deflector as claimed in claim 1, 2 or 3 wherein the length of the lower trailing edge is not greater than that of the upper leading edge.
Claim 7
Dependent Claim
39 words
The aerodynamic deflector as claimed in claim 1, 2 or 3 wherein the length of the lower trailing edge is not greater than that of the upper leading edge and there is defined straight lateral margins between both edges.
Claim 8
Dependent Claim
25 words
The aerodynamic deflector as claimed in claim 1, 2 or 3 wherein the lower trailing edge is greater in length than the upper leading edge.
Claim 9
Dependent Claim
57 words
The aerodynamic deflector as claimed in claim 1, 2 or 3 wherein the lower trailing edge is a greater in length than the upper leading edge and lateral side margins of the aerodynamic deflector are continous concave sheets extending from the leading edge to the trailing edge, in a manner that continuously merge with the striking surface.
