Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
155 words
Apparatus for balancing wheels having a hub disc with inner and outer peripheral edges and a pneumatic tyre mounted between said edges, the apparatus comprising, a frame, a shaft mounted in said frame for rotating the wheel, and sensing means spaced from one another along said shaft for obtaining dynamic and positional data on any imbalance of the wheel, computing means, a feeler arm mounted to said frame so as to be angularly movable about and along an axis parallel with the wheel axis, said feeler arm having contact means for contacting said edges of said hub disc, and means for detecting the axial and angular position of said arm, to obtain data on the diameter of said hub disc and the axial distance between said edges, said computing means receiving data from said sensing means and said detecting means and deriving therefrom information on the position and the amount of imbalance in the wheel.
Claim 2
Dependent Claim
155 words
Apparatus for balancing wheels having a hub disc with inner and outer peripheral edges and a pneumatic tyre mounted between said edges, the apparatus comprising, a frame, a shaft mounted in said frame for rotating the wheel, and sensing means spaced from one another along said shaft for obtaining dynamic and positional data on any imbalance of the wheel, computing means, a feeler arm mounted to said frame so as to be angularly movable about and along an axis parallel with the wheel axis, said feeler arm having contact means for contacting said edges of said hub disc, and means for detecting the axial and angular position of said arm, to obtain data on the diameter of said hub disc and the axial distance between said edges, said computing means receiving data from said sensing means and said detecting means and deriving therefrom information on the position and the amount of imbalance in the wheel.
Claim 3
Dependent Claim
51 words
Apparatus according to claim 1, further com- prising a sliclable and angularly movable rod by means of which said arm is mounted to said frame, said detecting means comprising two potentiometers associated with said rod for detecting the axial and angular position of said rod and therefore of said feeler arm.
Claim 4
Dependent Claim
45 words
Apparatus as claimed in claim 1, wherein said contact means comprises two opposite, transversely extending feelers intended to rest respectively and in succession on the two edges of the hub disc of the wheel, substantially at one and the same radial position of the wheel.
Claim 5
Dependent Claim
44 words
Apparatus as claimed in claim 2 or 3, further comprising a cable connected to said rod, a drum around which the cable is wound so that axial movement of the rod causes rotation of the drum, one said potentiometer being coupled to said drum.
Claim 6
Dependent Claim
31 words
Apparatus as claimed in anyone of claims 2to 4, further comprising push button means which on actuation sense the settings of said potentiometers and send this data to said computing means.
Claim 7
Dependent Claim
14 words
Apparatus as claimed in Claim 5, wherein said push button means are manually operable.
Claim 8
Dependent Claim
30 words
Apparatus as claimed in Claim 5, wherein said push button means are associated with said contact means and are automatically operated when said contact means contacts one of said edges.
Claim 9
Independent Claim
221 words
A device for measuring the radius and thickness of a wheel having a rim, for use in wheel balancing apparatus, the device comprising a frame, a shaft for mounting the wheel carried on said frame, 1; 4 1 3 GB 2 139 772 A 3 a rod slidably mounted to said frame parallel to said shaft and rotatable about its own axis, a feeler arm fixedly mounted to one end of said rod, said arm carrying a contact member for engaging the wheel at its rim on each side of the wheel, a first potentiometer having an angularly movable contact coupled to a fixed point on the rod, the resistance of said first potentiometer representing the angular position of said rod, and a second potentiometer having a contact movable in relation to the axial movement of the rod, the resistance of said second potentiometer representing the axial position of said rod, the radius of the wheel being measured by bringing said contact member into contact with said rim and measuring the resistance of said first potentiometer and deriving the radius therefrom, the thickness being measured by bringing said contact member into contact with said rim successively on each side of the wheel and measuring the resistance of said second potentiometer and deriving the thickness from the difference between the two resistances.
Claim 10
Independent Claim
221 words
A device for measuring the radius and thickness of a wheel having a rim, for use in wheel balancing apparatus, the device comprising a frame, a shaft for mounting the wheel carried on said frame, 1; 4 1 3 GB 2 139 772 A 3 a rod slidably mounted to said frame parallel to said shaft and rotatable about its own axis, a feeler arm fixedly mounted to one end of said rod, said arm carrying a contact member for engaging the wheel at its rim on each side of the wheel, a first potentiometer having an angularly movable contact coupled to a fixed point on the rod, the resistance of said first potentiometer representing the angular position of said rod, and a second potentiometer having a contact movable in relation to the axial movement of the rod, the resistance of said second potentiometer representing the axial position of said rod, the radius of the wheel being measured by bringing said contact member into contact with said rim and measuring the resistance of said first potentiometer and deriving the radius therefrom, the thickness being measured by bringing said contact member into contact with said rim successively on each side of the wheel and measuring the resistance of said second potentiometer and deriving the thickness from the difference between the two resistances.
