Therefore, the accuracy of the repair can be guaranteed 100%, but still depends on the user
[0005] In addition, determining the jacking force that needs to be applied is very complicated, in this regard, consideration was given to using wheel balancing equipment of a known type and commercially available to verify the degree of deformation and thereby quantify the accuracy at a subsequent repair stage
However, in this case, performing the check whenever a single jacking force is applied to the rim represents a clear waste of time

Embodiment Construction
[0022] figure 1 An embodiment of the device according to the invention is shown, 1 designating the supporting frame of said device, in which a rod 2 is engaged to an actuation device 101 connected to a detection device 201 which in turn is connected to a central processing Unit 301 , the central processing unit provides acquired and processed data to the monitor 401 . The rod 2 has, at the end opposite to the end connected to said actuating means 101 , a threaded portion 102 which engages a rim fixing bush 112 provided with clamping means 122 . As can be seen more clearly in the following figures, the threaded portion terminates in a disc 202 which is keyed to the rod 2 . The means 3 for guiding the pushers 4 and 4' are arranged concentrically with the rod 2, while the pushers 4 and 4' are connected together by means of a clamp 104. Said guide means 3 are stably connected to a bracket 5 protruding from the frame 1 in the following manner.

Apparatus for restoring the centering of tire rims, comprising: a rod (2) which can be inserted into the centring hole (11) for engaging a rim (10) with the hub of a motor vehicle and provided with means (202, 212, 102, 112) for locking, coaxial with the said rod, the fixing plate (13) of the said rim (10) so as to position said rod (2) along the direction of the axis of said rim (10); thruster means (4, 4') able to act in any direction perpendicular to the said rod (2), movable in a direction parallel to the rod (2) itself and provided with adjusting and support means (3, 104) and means (164, 174) for fixing their position along the said rod (2), said rod (2) being mounted- rotatably relative to its axis, provided with actuating means (101) -and connected to means (201, 301,401) for detecting the balancing and geometrical deformation; as well as a method for use thereof.
Description
technical field [0001] The invention relates to a device for restoring or restoring the centering condition of the rim of a tire. Background technique [0002] The increasingly widespread use of alloy rims as standard fittings on motor vehicles and as components for special optional applications, and their often combination with tires commonly referred to as "low profile tires," has resulted in the occasional The deformation problem is more prominent when hitting obstacles such as sidewalks, stones, holes, etc. and the tire is not elastic enough to absorb all the external forces. Until recently, this damage was repaired with the aid of an essentially manual operation, knocking on the damaged rim section, resulting in dents and near centering. Some advanced operators in this field use lathes for this repair, but there are significant limitations in centering which in many cases result in damage to the rim structure and the failure to ensure proper and safe operation of the r...
