Abstract
Abstract This invention relates to a device for balancing out-of-balance bodies, particularly motor vehicle wheels, wherein the unbalance is determined in two planes of correction a and b, which has sliding and clamping means by which the out-of-balance body can be so displaced and clamped on a main shaft that the correction plane a will coincide with one of the two main shaft bearings, said bearing being adapted as a radially fixed swing bearing and the other bearing being radially movable and connected to a transducer and measuring means and an indicating instrument so that the out-of-balance is determined and eliminated in a first measuring run in correction plane b whereupon the out-of-balance is ascertained in correction plane a.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
A device for balancing out-of-balance bodies, particularly motor vehicle wheels, with respect to two axially spaced, radially extending correction planes comprising: a main shaft; a radially fixed, swing main bearing supporting said shaft for rotation; a radially movable main bearing supporting said shaft at an axially spaced disposition from said radially fixed, swing main bearing; clamp means received upon main shaft, said clamp means being configured for selectively clamping an out-of-balance body on said shaft with the first of said two correction planes radially coinciding with the radially fixed, swing main bearing; measuring and translating means associated with the radially movable main bearing for ascertaining and providing an output proportional to the out-of-balance in the second of said two correction planes, so the same may be eliminated, in a first step; a rigid, force measuring element supporting said radially fixed, main swing bearing; and translating means associated with said rigid, force measuring element for providing an output proportional to the out-ofbalance in the first of said two correction planes, after the out-of-balance determined for the second correction plane has been eliminated.
Claim 2
Independent Claim
181 words
A device for balancing out-of-balance bodies, particularly motor vehicle wheels, with respect to two axially spaced, radially extending correction planes comprising: a main shaft; a radially fixed, swing main bearing supporting said shaft for rotation; a radially movable main bearing supporting said shaft at an axially spaced disposition from said radially fixed, swing main bearing; clamp means received upon main shaft, said clamp means being configured for selectively clamping an out-of-balance body on said shaft with the first of said two correction planes radially coinciding with the radially fixed, swing main bearing; measuring and translating means associated with the radially movable main bearing for ascertaining and providing an output proportional to the out-of-balance in the second of said two correction planes, so the same may be eliminated, in a first step; a rigid, force measuring element supporting said radially fixed, main swing bearing; and translating means associated with said rigid, force measuring element for providing an output proportional to the out-ofbalance in the first of said two correction planes, after the out-of-balance determined for the second correction plane has been eliminated.
Claim 3
Dependent Claim
61 words
The device of claim 1 further including an indicating instrument; switch means for alternately connecting the indicating instrument to receive said output proportional to the out-of-balance in the second of said two correction planes and said output proportional to the out-of-balance in the first of said two correction planes, after the out-of-balance determined for the second correction plane has been removed.
Claim 4
Dependent Claim
48 words
The device of claim 1 wherein the second mentioned translating means includes variable resistance means for accounting for variation in the radius of said first correction plane; and means for connecting a varied resistance from said variable resistance means to the output from the rigid, force measuring element.
Claim 5
Dependent Claim
82 words
The device of claim 3 further Including an indicating instrument; switch means for alternately connecting the indicating instrument to receive said output proportional to the out-of-balance in the second of said two correction planes and said output proportional to the out-of-balance in the first of said two correction planes, after the out-of-balance determined for the second correction plance has been removed, wherein said variable resistance means and said connecting means are interposed between the rigid, force measuring element and said switch means.
Claim 6
Dependent Claim
44 words
The device of claim 3 wherein the variable resistance means is constituted by a plurality of resistors connected in series and said connecting means comprises a wiper for connecting a varied amount of said resistors to the output of the rigid, force measuring element.
Claim 7
Dependent Claim
41 words
The device of claim 4 wherein the variable resistance means includes a potientometer calibrated in diameters which are typical of the out-of-balance body, the indication provided by the indicating instrument being provided in familiar mass units, such as grams of unbalance.
Claim 8
Dependent Claim
56 words
The device of claim 1 further including spring loaded joint means forcing said radially fixed swing main bearing against the rigid, force mesuring element for transmitting radial forces developed in the radially fixed, swing main bearing, substantially undiminished, to the rigid, force measuring element without substantially inhibiting the swingability of said radially fixed, swing main bearing.
