Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
A vehicle having a chassis and wheels and an individual wheel suspension for connecting each of said wheels to said chassis, said wheel suspension comprising a single transverse lever, articulated joints connecting one end of said transverse lever to said chassis and the other end to said wheel, said chassis and wheel joints of said transverse lever having parallel pivot axes extending substantially in the direction of travel of the vehicle, a wheel-gauge holding device, articulated joints connecting one end of said wheel-gauge holding device to said chassis and its other end at least indirectly to said transverse lever, a longitudinal lever, universal joints connecting the opposite ends of said longitudinal level to said wheel and to said chassis, the points of connection of said wheel with said transverse lever and with said longitudinal lever being disposed substantially diametrically opposite to each other above and below the axis of rotation of said wheel, a hydraulic cylinder unit for adjusting and maintaining the camber of said wheel, and means for connecting the opposite ends of said cylinder unit at points spaced from said wheel joint of said transverse lever to said wheel and to said transverse lever, respectively.
Claim 2
Dependent Claim
197 words
A vehicle having a chassis and wheels and an individual wheel suspension for connecting each of said wheels to said chassis, said wheel suspension comprising a single transverse lever, articulated joints connecting one end of said transverse lever to said chassis and the other end to said wheel, said chassis and wheel joints of said transverse lever having parallel pivot axes extending substantially in the direction of travel of the vehicle, a wheel-gauge holding device, articulated joints connecting one end of said wheel-gauge holding device to said chassis and its other end at least indirectly to said transverse lever, a longitudinal lever, universal joints connecting the opposite ends of said longitudinal level to said wheel and to said chassis, the points of connection of said wheel with said transverse lever and with said longitudinal lever being disposed substantially diametrically opposite to each other above and below the axis of rotation of said wheel, a hydraulic cylinder unit for adjusting and maintaining the camber of said wheel, and means for connecting the opposite ends of said cylinder unit at points spaced from said wheel joint of said transverse lever to said wheel and to said transverse lever, respectively.
Claim 3
Dependent Claim
52 words
A vehicle as defined in claim 1, further comprising a hydraulic control cylinder unit for controlling said hydraulic camber-adjusting cylinder unit, the opposite ends of said control cylinder unit being mounted at two points spaced from each other at a distance depending upon the position of said wheel relative to said chassis.
Claim 4
Dependent Claim
40 words
A vehicle as defined in claim 2, in which both of said hydraulic cylinder units are double-acting and each of them has two cylinder chambers, and conduit means for connecting the corresponding cylinder chambers of both units with each other.
Claim 5
Dependent Claim
31 words
A vehicle as defined in claim 2, further comprising means for pivoting connecting one end of said control cylinder unit to said chassis and its other end to said transverse lever.
Claim 6
Dependent Claim
165 words
A vehicle as defined in claim 1, in which said articulated joints connecting said wheel to said transverse lever and to said hydraulic camber-adjusting cylinder unit and the latter to said transverse lever are universal joints, the wheel-side joints of said transverse lever of said camber-adjusting unit and of said longitudinal lever being disposed within a straight line forming the steering axis of said wheel, a steering arm secured to said wheel, said wheel-side joints of said camber-adjusting unit and of said longitudinal lever being connected to said steering arm, a second longitudinal lever, and a universal joint connecting one end of said second longitudinal lever to said steering arm at a certain distance from said steering axis; whereby the other end of said second longitudinal lever may be connected by another universal joint to said chassis if said wheel is not to be steerable, or it may be connected to a steering lever of a steering gear if said wheel is to be steerable.
Claim 7
Dependent Claim
36 words
A vehicle as defined in claim 5, in which said two longitudinal levers have a substantially equal length and extend substantially parallel to each other and are both connected by universal joints to said steering arm.
