Description

TURNING MACHINE FOR BRAKE DISK OF CAR AND MOUNTING ADAPTER}

The present invention relates to a brake disc turning machine for a vehicle and a mounting adapter, and particularly, when the turning machine body is installed on the wheel of the left side or the right side of the vehicle, the body of the turning machine is properly installed and coupled to the disc brake without regard to the position of the disc brake. The present invention relates to a brake disc turning machine and a mounting adapter for a vehicle, which can be used easily and can precisely turn a disk to improve maintenance reliability.

In general, disc brakes used in various automobiles combine a hydraulic cylinder and a pad with a caliper to a disc rotating with a wheel, and the brake pad attached to the lining brakes the disc by pressing the disc strongly by the force of the hydraulic cylinder. It is a simple system.

These disc brakes are simple in structure and light in weight, have good heat dissipation by being exposed to the atmosphere, stabilized braking performance by preventing fading, and prevent moisture from degrading due to moisture being scattered by centrifugal force. In addition, it is widely adopted in passenger cars because it is easy to check and adjust, and there is little change in braking force even after repeated use.

The disk brakes generally used in this manner are unevenly worn and worn out over a long period of time, and uneven portions are formed on the surface of the disk.

In this case, the noise of the vehicle is increased, the braking force is decreased, the braking distance is increased, and the driving phenomenon occurs during braking, the brake shaking and the vehicle body shaking occur during braking, and the vehicle is pushed in one direction by the braking. In addition to the occurrence of this, there is a problem that the performance is further reduced due to the change of material due to the thermal curing of the disk and the pad.

Therefore, when the disc is replaced in advance at an appropriate time in consideration of the mileage, etc., it is possible to prevent various problems due to the damage of the brake surface of the disc, so that the disc is damaged to maintain various performances related to the braking force of the vehicle. In this case, it must be replaced and must be replaced with a genuine product that is allowed by the manufacturer.

However, when replacing a disc with a genuine product, it is expensive for the customer, and since the profit is low for the vendor, the disc may be replaced with a non-standard product instead of a genuine product, and some customers do not have expertise. Even if you want to replace a standard product, you may be replaced with a non-standard product, unlike your intention, and there is a concern about ensuring the safety of the vehicle, and customers who do not like it avoid the replacement by deciding that the disk originally attached to the vehicle is safer. There was a case.

Therefore, a brake disc turning machine for turning and removing uneven wear and unevenness of the original disc attached to the vehicle has become widespread, and the use amount is increasing.

This conventional brake disc turning machine will be described with reference to the drawings.

6A and 6B are plan views illustrating a conventional turning machine coupled to left and right disc brakes, and FIG. 7 is an exploded perspective view showing a connecting member for coupling a conventional turning machine, in which 1 is a brake disc and 2 is a caliper. The support plate, 10 is a turning machine, and 20 is an adapter.

As shown in the drawing, the conventional turning machine 10 is coupled to the upper surface of the base plate 11 so that the slider 12 can be linearly moved back and forth.

The screw shaft 14 is coupled to the gear box 13 provided at the rear end of the base plate 11, and the distal end of the screw shaft 14 is rotatably connected to the slider 12, and the base plate ( A drive motor 30 is coupled to the lower portion of 11, and a plurality of reduction gears (not shown) are coupled to the gearbox 13, so that the driving force of the drive motor 30 is a plurality of gear trains. While passing through the train to the screw shaft 14, the screw shaft 14 is rotated by the power of the drive motor (30).

In addition, the handle 15 is fixed to the rear end of the screw shaft 14 so that the screw shaft 14 moves forward or backward by the rotational direction of the handle 15.

In this manner, cylindrical guide tubes 16 are provided at both front portions of the linearly moving slider 12, and both guide tubes 16 rotate the adjusting knob 18 coupled to the rear end of the bite holder 17. By moving, it is coupled so that it can move back and forth, and the bite 19 is being fixed to the front-end | tip part of the bite holder 17. As shown in FIG.

Adapter 10 for connecting and installing the turning machine 10 is made of a horseshoe-type fixed rod 21 and the connecting rod 22 connected between the fixed rod 21 and the caliper support plate (2) The support section 23 for supporting the base plate 11 of the turning machine 10 is integrally formed in the fixing section 21.

When turning the disc 1 of the brake using the conventional turning machine as described above, first, as shown in FIGS. 6A and 7, the adapter groove 20 is formed in the guide groove 11a formed on the bottom surface of the base plate 11. Insert the support protrusions 23 of the provided fixing section 21, and fasten by inserting a bolt into the long hole (23a) formed in the supporting protrusions 23, between the caliper support plate 2 and both ends of the fixing section 21 After installing the turning machine 10 by fastening with the bolt 24 via the connecting rod 22, the slider 12 is moved by rotating the handle 15, and the adjusting knob 18 is rotated. By moving the bite holder 17, the bite 19 is positioned at the point where the turning of the brake disc 1 is to be started, and power is supplied to the drive motor 30 to automatically turn.

When the drive motor 30 is driven, the screw shaft 14 is rotated by the rotational force of the drive motor 30, and the slider 12 is moved rearward by the rotation of the screw shaft 14, so that the disc ( When the bite 19 in close contact with the surface of 1) moves while turning the surface of the disk 1 from the inside to the outside, such turning is performed two to three times depending on the surface shape of the disk 1. The surface of the disk 1 is cleanly turned.

In this way, after turning the disk 1 of one wheel, if the disk 1 of the other wheel is to be turned, the fixed section 21 and the connecting section 22 of the adapter 20 are separated, 6b is installed on the opposite side of the caliper support plate 2 on the opposite side and the connecting rod 22 is installed to install the turning machine 10, and then the opposite disk 1 is turned in the same manner as above. .

Since the conventional turning machine as described above installs the turning machine 10 by using the horseshoe-shaped fixing rod 21 and the connecting rod 22, as shown in FIG. 6A, when turning one disk 1, the turning machine Although 10 is correctly installed, as shown in Fig. 6B, when turning the disk 1 on the opposite side, a problem arises in that the turning machine 10 is installed outward.

As shown in FIG. 6A, when the turning machine 10 is properly installed, the turning machine 10 can be coupled to the correct position, can be safely supported, and the bite 19 can be stably moved in accordance with the movement of the slider 12. Since the surface of the disk 1 can be precisely scraped off, but when installed upside down, as shown in FIG. 6B, it is difficult to engage the turning machine 10 in the correct position, and it is difficult to securely support the slider 12. There was a defect that the linear motion of the and bite 19 became unstable and the disk 1 could not be precisely shaved off.

In the conventional turning machine, since the cylindrical guide tube 16 to which the bite holder 17 is coupled is formed to be inclined at both ends of the slider 12, the cylindrical guide tube 16 is formed in a narrow area where the disc brake device is configured. It is difficult to insert the, and it is difficult to adjust the contact angle of the bite 19 in contact with the surface of the disk 1 in a narrow space, so that the turning operation of the disk cannot be performed depending on the vehicle type.

Therefore, the present invention was devised to solve the above-mentioned conventional defects and problems, and when the turning body is installed on the wheel of the left side or the right side of the vehicle, the turning body can be corrected without regard to the position of the disc brake. It is an object of the present invention to provide a brake disc turning machine for a vehicle and an adapter for mounting a vehicle, which can be used in a simple manner and can be easily used and improve the reliability of maintenance by turning the disc precisely.
