Abstract
The utility model relates to a disc brake device and belongs to the field of braking. A brake friction piece is fixedly connected with a brake block which is connected with a brake caliper body through a bolt. One side of a brake disc is of a V-shaped annular groove structure, and the brake friction piece on the corresponding side of the above side of the brake disc is of a V-shaped annular groove structure corresponding to the brake disc. According to the disc brake device, the contact area between the friction piece and the brake disc is enlarged, the ratio of the outer diameter to the inner diameter of the brake friction piece is reduced, the abrasion unevenness degree of the outer edge of the brake friction piece and the inner side circumference of the brake friction piece is reduced, the brake torque variation is small, service life is prolonged, and the radiating efficiency is improved. Under the condition that the pressure of a brake pipeline is not changed, the friction area and the brake force are increased by 41%-100%.
Description
Technical field
The utility model belongs to brake field, refers in particular to a kind of Disk brake apparatus.
Background technique
Existing disk type braker mostly is plane type brake disc and brake strip, and brake strip work area is little, quick abrasion, and working life is low.For guaranteeing braking effect, cannot reduce the outer radius of brake strip and the ratio of inside radius and the angle of circumference of brake strip simultaneously, when not increasing the angle of circumference of brake strip, can only increase the outer radius of movable friction plate and the ratio of inside radius, cause brake strip outer rim and inside circumference wearing and tearing inhomogeneous, cause the most at last braking moment to change greatly.
Summary of the invention
The utility model provides a kind of Disk brake apparatus, little to solve the brake strip work area existing at present, quick abrasion, the problem that working life is low.
The technical solution of the utility model is: brake strip is fixedly connected with brake slipper, brake slipper is connected with braking clamp body by bolt, brake disc one side adopts V-type ring channel structures, the brake strip of a corresponding side adopts the V-type ring channel structures corresponding with brake disc, and this V-type circular groove angle is 60 ° ~ 90 °.
The utility model advantage is novel structure, increased the area of contact of friction plate and brake disc, reduced the ratio of brake strip outer radius and inside radius, brake strip outer rim and inside circumference wearing and tearing nonuniformity have been reduced, braking moment is changed little, increase working life, improve radiating efficiency.In the situation that brake-pipe pressure is constant, friction area and braking force increase by 41% ~ 100%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the I portion enlarged view of Fig. 2.
Embodiment
Brake strip 2 is fixedly connected with brake slipper 3, brake slipper 3 is connected with braking clamp body 4 by bolt, brake disc 1 one sides adopt V-type ring channel structures, and the brake strip 2 of a corresponding side adopts the V-type ring channel structures corresponding with brake disc 1, and this V-type circular groove angle is 60 ° ~ 90 °.
In this angular range, friction area increases by 41% ~ 100%, and braking force increases by 41% ~ 100%.
Claims (2)
1. a Disk brake apparatus, brake strip is fixedly connected with brake slipper, brake slipper is connected with braking clamp body by bolt, it is characterized in that: brake disc one side adopts V-type ring channel structures, and the brake strip of a corresponding side adopts the V-type ring channel structures corresponding with brake disc.
2. a kind of Disk brake apparatus according to claim 1, is characterized in that: described V-type circular groove angle is 60 ° ~ 90 °.
