Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to a pad clip for a disc brake.

(Background of the Idea) Conventionally, in order to support the friction pads of disc brakes, pad clips are often interposed between the friction pads and a fixed support. This pad clip is usually provided for the main purpose of providing a low-friction surface made of rust-resistant and rust-resistant material to ensure smooth sliding of the friction pad, or to prevent rattling of the friction pad.

Figure 3 shows such a conventional padded clip 2.
0, from the mounting plane part 21 which is screwed to the surface of the fixed support (not shown) opposite to the rotor, in the rotor circumferential direction between the fixed support and the friction pad. A continuous curved surface 22 extending almost entirely over the concavo-convex mating surface is formed.

However, in a padded clip with this type of shape, the functions of each part are provided all at once by the continuous bending surface 22, so when vibration absorption is transmitted between them, abnormal noise may be generated or unnecessary noise may be generated. There is also a risk of damage due to impact.

(Purpose of the invention) This invention was made to solve the problems with the invention, and its purpose is to provide a padded clip as a set of padded clips in which different functional parts of each part do not affect each other. It's there to do.

(Summary of the invention) The features of the pad clip of the present invention, which has been made for this purpose, include a friction pad and a fixed support having pad sliding support surfaces that engage with both sides of the rotor in the circumferential direction. a pad clip that is attached to a fixed support and covers the sliding support surface of the pad, and the engagement of the friction pad with the fixed support is achieved by a concave portion formed on the rotor circumferential side of the friction pad. In a disc brake that is provided by fitting into a support, the pad clip connects the fixed support and the friction pad from a mounting plane fixed to the surface of the fixed support opposite to the rotor. a first member having first and second sliding surface portions each independently bent and inserted between a rotor circumferential engagement surface and a rotor radially outward engagement surface; An elastic member for preventing looseness is inserted between the rotor radially inward engagement surface of the fixed support and the friction pad, and overlaps the mounting plane and is inserted from the mounting plane that is fixed to the fixed support. It is configured by a combination of a second member having a surface portion.

(Example of idea) The present invention will be explained below based on the drawings.

FIG. 1 shows a part of a disc brake to which the present invention is applied, and in the figure, 1 is a caliper of a known structure arranged to straddle a rotor (not shown), and a fixed support spaced apart in the circumferential direction of the rotor. It is supported movably in the rotor axial direction by a pair of arm portions (only one of which is shown in the figure) 2 of the body via a sliding support device (not shown).

Reference numeral 3 denotes a friction pad, the side surface of which in the rotor circumferential direction is formed to have a generally concave portion 4, and the arm portion 2 is formed so that the concave portion 4 fits with the arm portion 2 of the fixed support. The rotor is slidably supported in the axial direction of the rotor.

In this example, the arm portion 2 of this fixed support body,
It has a structure in which the illustrated pad clip is attached to the concave and convex fitting portion of the concave portion 4 of the friction pad 3.
This pad clip of this example has a first flat part 5b inserted between the engaging surfaces in the circumferential direction of the rotor, and a second flat part 5b inserted between the engaging surfaces on the radially outer side of the rotor.
c is on the surface of the arm portion 2 opposite to the rotor,
A first member 5 bent and extending from a mounting plane part 5a fixed by screws 7, and a mounting plane part 6a fixed to the arm part 2 of the fixed support body by screws like this first member 5. It is made up of a second member 6 with a twist. The attachment of the second member 6 with screws is normally provided by a loose fit in the hole. Reference numeral 6b denotes a flat portion bent and extended from the attachment flat portion 6a of the second member 6 so as to be inserted between the arm portion on the radially inner side of the rotor and the concave portion.

The first and second flat parts of the first member 5 are for providing sliding surfaces for the friction pad, and
None of them have a spring action, and are independent bent extensions that are not connected to each other except for the connection with the mounting plane part 5a, and as a result, cracks may occur due to the mutual influence of deformation between the two parts. This will not cause any problems.

FIGS. 2A and 2B show these first member 5 and second member 6 individually.

According to such a configuration, the first member 5 whose main purpose is to provide a surface for receiving torque pressure with a low coefficient of friction, and the second member whose main purpose is to prevent rattling of the friction pad 3. 6 and 6, there is an advantage that materials can be selected and configured to suit the needs of having sufficient strength to withstand torque pressure and the function of eliminating looseness, etc., and each functional part does not affect each other. This has the advantage that they do not match each other, and its practical effects are great.

(Effects of the invention) According to the invention, the performance of the pad clip of the disc brake can be fully demonstrated in accordance with the desired design, and there will be no defects due to mutual influence of the functional parts, resulting in improved durability. However, favorable advantages can be obtained, and its practical effects are great.
