Description

[0001] Technical field

[0002] This utility model relates to devices for centering vehicle wheels on a balancing machine, particularly for wheels with a large center bore. The device can be used for balancing truck and minibus wheels using universal balancing cones with a wide cone range on specialized balancing machines.

[0003] Technology Level

[0004] The closest analogue to the claimed utility model is the Haweka spacer washer, presented as a kit with a balancing cone in the source https: / / www.haweka.ru / catalog / cones / 150_400_091 / (archived in the Internet Archive library on December 9, 2017). The spacer washer consists of a single, one-piece housing with a central hole for mounting on the balancing machine shaft. One surface of the housing acts as a stop for the vehicle wheel.

[0005] The main disadvantage of this spacer washer is its increased material consumption and, consequently, increased machining time. This is due to the fact that the spacer washer is machined from a single, large-diameter blank that runs the entire length of the part, and most of the material is lost as chips.

[0006] Thus, the technical problem that the claimed utility model is aimed at solving is the reduction of material intensity in the production of the product.

[0007] Disclosure of the essence of the utility model

[0008] The technical result of the utility model is a reduction in the material consumption (material intensity) in the manufacture of the device by making it prefabricated from a flange (1) and at least three stops (2), which allows the use of blanks that are close in shape to the parts of the finished product, for example, the flange (1) is cut by laser from a sheet, the stops (2) from a rod, without removing a large volume of material into chips.

[0009] This technical result is achieved by manufacturing the balancing spacer not from a single, massive blank with a large diameter along its entire length, but from a flange (1), which can be cut, for example, on a laser machine, and at least three stops (2) made from small-diameter rod. This eliminates time-consuming rough turning, and requires only finishing the device parts to the desired shape and connecting the flange to the stops, for example, by threaded connection. The choice of connection type does not affect the technical result, as long as the stops on the flange remain motionless during operation of the device under load.

[0010] Thus, the presence of all the essential features of a utility model reduces the material consumption of the finished device.

[0011] Brief description of drawings

[0012] The utility model is illustrated by figures, where:

[0013] Fig. 1 shows a top-angle view of the device;

[0014] Fig. 2 shows a view of the device from below at an angle;

[0015] Fig. 3 shows a top view of the device;

[0016] Fig. 4 shows a side view of the device.

[0017] The structural elements are indicated on the figures by the following positions:

[0018] 1 - flange;

[0019] 2 - stop;

[0020] 3 - hole.

[0021] Implementation of a utility model

[0022] The claimed device includes a flange (1) and at least three stops (2), interconnected in a manner that ensures their relative fixation during operation. Each stop (2) has a fixed connection to the flange (1) under a load created by the quick-release nut of the balancing machine. The flange (1) has a hole (3) for mounting on the shaft of the balancing machine with the ability to move axially.

[0023] In the embodiment corresponding to clause 2 of the formula, the device has three stops (2) - the minimum permissible number of stop points that can create stable contact of the balancing spacer with the vehicle wheel. There may be more stops (2), but not less than three. In the embodiment corresponding to clause 3 of the formula, the stops (2) have a cylindrical shape. In the embodiment corresponding to clause 4 of the formula, the stops (2) are made of polyamide. The choice of the shape and material of the stops does not affect the achievement of the technical result - a reduction in material consumption due to the prefabricated structure. The connection of the flange (1) and the stops (2) in the embodiment corresponding to clause 5 of the formula is ensured by means of a threaded connection, which ensures their fixation during operation. Other known methods can be used to connect the flange (1) and the stops (2), ensuring their fixation relative to each other during operation.The choice of a specific fixation method does not affect the achievement of the technical result - a reduction in material consumption due to the prefabricated structure.

[0024] The device is used as follows.

[0025] The balancing spacer is placed on the machine shaft through the hole (3) in the flange (1) until the flange (1) rests against the bearing cup of the balancing machine. The hole (3) has a diameter corresponding to the diameter of the machine shaft, ensuring unimpeded axial movement along the shaft and a minimum gap between them. The vehicle wheel to be balanced is placed on the machine shaft until it rests against the balancing spacer, while the stops (2) of the declared device should rest against the vehicle wheel rim. The balancing cone is placed on the machine shaft, and its conical surface comes into contact with the central hole of the wheel rim. The quick-release nut is screwed onto the shaft until it stops against the balancing cone.When tightened, the conical surface of the balancing cone is pressed against the wheel, the wheel is pressed against the stops (2) of the balancing spacer, and the spacer is pressed against the balancing machine's thrust cup, thus ensuring the car's wheel is centered relative to the balancing machine shaft. The balancing spacer device acts as an expander for the inner bore of the standard balancing machine's spacer cup, which accommodates the universal balancing cone with its wide conical diameter. The device also moves the wheel away from the balancing machine's housing and attachments, ensuring its unimpeded rotation.
