Description

Technology Field

[0001] The present invention relates to a clamp, and more specifically, to a clamp that supports an outer ring when forming the end into which an inner ring bearing is inserted, which is configured in a hub bearing. Background Technology

[0003] First, if we look at the prior art,

[0004] Automobile manufacturers are increasingly using packaged components during vehicle assembly.

[0006] Often, outsourcing suppliers provide these parts, allowing manufacturers to reduce costs and the burden of maintaining or repairing manufacturing facilities for these parts.

[0008] The automotive hub assembly is one of the representative components suitable for outsourced manufacturing.

[0010] Many automobiles and sports utility vehicles manufactured today are all equipped with independently suspended wheels.

[0012] Packaged hubs perform well in mounting the wheels of these vehicles onto the vehicles' independent suspension systems.

[0014] A typical hub assembly comprises a hub having a flange to which a wheel and a brake disc or drum are fixed, and a spindle protruding from the hub into a housing.

[0016] Here, the spindle rotates on a bearing inside the housing.

[0017] The above housing is again attached to a suspension component such as a steering knuckle. The bearing usually takes the form of a double row tapered roller bearing or a double row angular contact ball bearing.

[0019] Either one accommodates radial loads in both axial directions, and additionally thrust loads.

[0021] Furthermore, hub assembly manufacturers typically eliminate radial and axial clearances within the bearing by setting the bearing with a slight preload.

[0023] This allows the hub of the hub assembly to rotate about a fixed axis relative to the housing, but does not exclude runout within the hub flange.

[0024] And, runout within the flange is converted into runout within the brake disc in contact with the flange.

[0026] Runout within the brake disc causes uneven brake wear, and when such brakes are applied, it produces a pulsating sensation known as 'brake judder'.

[0028] Conventional brake disc measuring devices and methods are used by measuring the brake disc while it is seated and fixed to a rotating spindle; however, this method has a problem in that it cannot rotate concentrically due to tolerances arising during the assembly of the rotating spindle and the bearing, as well as tolerances of the bearing itself.

[0030] In addition, the condition of the seating surface of the brake disc and the seating surface of the rotating spindle has a significant impact on determining whether there is a defect, and there is a problem in that the pad flatness of the brake disc cannot be precisely measured when rotating with foreign matter inserted between the seating surface of the brake disc and the seating surface of the rotating spindle.

[0031] [

[0032] In addition, when the mounting cone of the rotating spindle into which the hole of the brake disc is inserted to seat the brake disc is smaller than the inner diameter of the brake disc, there is a problem in that the disc rotates unstably during rotation.

[0034] When such problems occur, there are issues that cannot be precisely measured, such as wobbling of the brake disc pad surface and thickness deviation.

[0036] Accordingly, although the 'hub bearing for an automobile knuckle spindle' disclosed in Publication No. 1998-031411, the 'bearing device for a vehicle wheel' disclosed in Registration No. 10-0923722, the 'wheel bearing assembly and method for assembling the same' disclosed in Registration No. 10-1327941, and the 'wheel bearing and method for manufacturing the same' disclosed in Registration No. 10-1779788 have been improved, the aforementioned problems remain unresolved. The problem to be solved

[0038] Accordingly, the present invention was devised to solve the problems of the aforementioned prior art, and has been completed as a technical objective with a focus on providing a clamp for supporting the outer ring of a hub bearing, wherein, by configuring a support member that contacts and supports the outer ring plate, the outer ring plate can rotate when the force (pressure) applied to the inner ring during the forming of the end into which the inner ring bearing is inserted exceeds a certain force (pressure) set by the user, thereby minimizing damage to the end into which the inner ring bearing is inserted during forming. means of solving the problem

[0040] Accordingly, the present invention provides a clamp for supporting an outer ring plate formed on the outer ring when the end of the inner ring is formed in the inner ring and outer ring of a hub bearing of an automobile, the clamp being configured to support the outer ring plate formed on the outer ring, wherein the clamp is configured on a main body, and is configured with an upper plate formed on the upper side of the main body, a column connected to the upper plate, a spring formed on the outer circumference of the column that moves up and down by pressure, a lower plate that supports the lower part of the spring and is connected to the column, and a pad formed on the inner side of the lower plate that presses the upper side of the outer ring plate. Effects of the invention

[0042] According to the clamp supporting the outer ring of the hub bearing of the present invention, the support rotates when the force exceeds a certain level during the forming of the inner ring, thereby preventing or minimizing damage during the forming of the inner ring, and preventing the occurrence of double teeth when there are teeth on the inner ring, and thus the invention has great effects.

Specific details for implementing the invention

[0045] Hereinafter, the preferred configuration and operation of the present invention for achieving the above objective in relation to the attached drawings will be described with reference to FIGS. 1 to 7 as follows.

[0047] First, the clamp (10) supporting the outer ring of the hub bearing of the present invention is,

[0048] In a clamp (10) that supports an outer ring plate (31) formed on the outer ring (30) when forming the end (21) of the inner ring in the inner ring (20) and outer ring (30) formed in the hub bearing of a vehicle, the clamp is formed on the main body and is composed of an upper plate (100) formed on the upper side of the main body, a column (200) connected to the upper plate (100), a spring (300) formed on the outer circumference of the column (200) and moving up and down by pressure, a lower plate (400) that supports the lower part of the spring (300) and is connected to the column (200), and a pad (500) formed on the inner side of the lower plate (400) and pressing the upper side of the outer ring plate (31).

[0050] To explain the present invention described above in more detail,

[0052] First, the clamp (10) used in the present invention is a device for supporting the outer ring plate (31) when forming the end (21) of the inner ring (20) in the inner ring (20) and outer ring (30) configured in the hub bearing of an automobile.

[0054] Accordingly, the present invention comprises a main body, and each of the following components is connected to the main body.

[0056] The upper plate (100) is configured on the upper side of the main body and supports the connected column (200).

[0058] The column (200) is connected to the upper plate (100) and the lower plate (400) described below, respectively.

[0060] One or more locking grooves are formed in the above column (200), and a locking member (220) is configured to be fitted into the locking grooves to prevent the spring (300) from returning.

[0062] The spring (300) is configured on the outer circumference of the column (200) and moves up and down under pressure.

[0063] The above spring (300) is pressed with a force (pressure) set by the user, and due to the pressure of the above spring (300), the pad (500) presses the outer ring plate (31).

[0064] Afterwards, a forming mold is pressed against the end (21) of the inner ring (20) to form (form) the forming process.

[0065] When performing the forming operation with the above forming mold, the force applied by the spring (300) becomes maximum, and as a result, the force with which the pad (500) presses the outer ring plate (31) also becomes maximum.

[0067] The lower plate (400) is configured to support the lower part of the spring (300) and to be connected to the column (200).

[0069] The lower plate (400) above is configured with a bearing (410) for horizontal rotation of the pad (500).

[0070] With the configuration of the above bearing (410), when the outer ring plate (31) exceeds a certain rotational force (pressure), the outer ring plate (31) rotates.

[0071] This means that if the pressing force of the tool generated during the forming operation becomes greater than the force set by the user, the outer ring plate (31) is rotated to disperse the force applied to the forming (forming).

[0073] The pad (500) is configured on the inner side of the lower plate (400) and is configured to press the upper side of the outer ring plate (31).

[0075] The above pad (500) is configured with one or more protrusions (510) that increase friction with the outer ring plate.

[0076] In addition, on one side of the pad (500), a resin pad (520) made of a soft synthetic resin is configured in the part that contacts the outer ring plate (31).

[0078] A rotating pulley (600) that assists in the rotation of the pad (500) is configured at the bottom of the lower plate (400).

[0080] Accordingly, the operation using the clamp (10) of the present invention is explained as follows:

[0081] [Stage 1]

[0082] The inner ring (20) and the outer ring (30) are formed, and the end of the inner ring (21) to be formed is placed at the position to be formed, and the pad (500) of the clamp (10) is mounted on the outer ring plate (31).

[0084] [Stage 2]

[0085] The pad (500) is pressed against the outer ring plate (31) by applying pressure to the spring (300).

[0087] [Stage 3]

[0088] The forming frame is moved to position it at the end (21) of the inner ring.

[0090] [Stage 4]

[0091] The end (21) of the inner ring is formed by the operation of the forming mold.

[0093] [Step 5]

[0094] After molding is complete, return the forming mold to its original position to complete the operation.

[0096] [Step 6]

[0097] The clamp (10) is attached to and detached from the outer ring plate (31).

[0099] Accordingly, the present invention allows the force applied to the inner ring end (21) to be dispersed so that the inner ring end (21) can be prevented from wearing out or becoming defective before the inner ring end (21) is worn out or becomes defective due to the force applied to the inner ring end (21) during the fourth step of forming, by rotating the outer ring plate (31) with the configuration of the pad (500) and bearing (410) configured in the clamp (10).

[0101] According to the present invention as described above, processing of the weldment processing location of the end plate can be performed using a laser oscillator, including peeling, cleaning, and heat treatment. This results in a uniform area of ​​the peeled portion during the peeling process, removal of foreign substances during the cleaning process, and the ability to perform partial heat treatment. Additionally, electrical resistance is reduced, moisture ingress into the weldment is blocked, cracks in the weldment are prevented, and rust formation is suppressed. Furthermore, power consumption is reduced due to the reduction in resistance and voltage, resulting in increased power efficiency for the battery. Explanation of the symbols
