Problems solved by technology

Therefore, the existing braking device has the problem of poor braking effect or easy wear of one component
For example, in a braking device that combines a non-steel pad made of a soft resin component and a harder cast iron rotor to generate friction through adhesive friction, there is a problem that the braking effect is poor.
In addition, in a brake device that combines a low-carbon steel pad made of hard steel fibers with a softer cast iron rotor to generate friction through abrasive friction, there is a problem that the rotor wears heavily.

Embodiment Construction

[0030] Next, a brake device according to an embodiment of the present invention will be described with reference to the drawings.

[0031] In the first embodiment of the present invention, the brake device of the present invention is applied to a disc brake of an automobile. Such as figure 1 As shown, a disc brake generates friction by pressing a pad 100a against a rotating brake disc 200a.

[0032] as from figure 1 side view viewed in the z direction of the figure 2 As shown, the friction surface 101 of the pad 100a abuts against the friction surface 201 of the brake disc 200a. as figure 2 A magnified view of part A of image 3 As shown, in this embodiment, a plurality of plate-shaped or rod-shaped hard particles 102 , 202 are elastically supported on the friction surfaces 101 , 201 . The hard particles 102 on the friction surface 101 of the pad 100a are supported such that their longitudinal direction is inclined in the direction opposite to the direction in which th...

Abstract

In a brake device comprising a pad (100a) having a friction surface (101) and a brake disc (200a) having a friction surface (201) sliding relative to the friction surface (101), the pad (100a) is The surface (101) includes a plurality of hard particles (102) inclined to the opposite direction of the sliding direction of the friction surface (201) relative to the friction surface (101), and the brake disc (200a) includes on the friction surface (201) A plurality of hard particles (202) inclined toward the sliding direction of the friction surface (201) relative to the friction surface (101). This increases the force with which the hard particles (102, 202) press each other. In addition, as a result of increasing the pressing force of the hard particles (102, 202) against each other, the distance between the friction surfaces (101, 201) decreases. Therefore, a large frictional force can be obtained.

Description

technical field [0001] The present invention relates to a brake device and a method for manufacturing a friction member, in particular to a brake device including a pair of friction members with friction surfaces and a method for manufacturing the friction member with friction surfaces. Background technique [0002] A conventional brake device for automobiles comprising a pad and a rotating body (disk) is a combination of a relatively hard member and a relatively soft member. Therefore, the existing braking device has the problem of poor braking effect or easy wear of one component. For example, there is a problem of poor braking effect in a braking device that combines a non-steel pad made of a soft resinous component and a harder cast iron rotor to generate frictional force through adhesive friction. In addition, in a brake device that combines a low-carbon steel pad made of hard steel fibers with a softer cast iron rotor to generate friction through abrasive friction, th...
