Description
Technical field
The present invention relates to automobile brake technical field, particularly relate to a kind of heat-dissipation type disc brake pad.
Background technique
Brake block is the power unit that automobile carries out braking in the process of moving, and brake block is by clamping the brake disc with tyre rotation, and brake block and brake disc rub, and the traveling kinetic energy of automobile is converted to heat energy, thus realizes the brake operating of automobile.In braking process, carry out friction between brake block and brake disc and gather a large amount of heat energy at short notice, when especially carrying out Emergency braking in running at high speed, the temperature of brake block can gather rising at short notice; After the temperature of brake block rises to certain value, the braking effect of brake block significantly can go down and even lose efficacy.
Therefore, the heat dispersion of brake block is the key element affecting brake block braking effect.
In prior art, in order to solve the problems of the technologies described above, generally, the straight trough perpendicular to its length direction is provided with in the middle part of the brake pad of brake block, in braking process, the heat that drag friction produces can be discharged by straight trough, thus dispels the heat to brake pad, further, drag friction produce dust and rainwater also can discharge along straight trough.But straight trough is arranged on the middle part of brake pad, Homogeneouslly-radiating cannot be carried out to whole brake pad, further, sense of rotation and the straight trough of brake disc are perpendicular, and the radiating effect of straight trough is also poor, in addition, dust also easily accumulates in straight trough, thus have impact on the stability of brake pad; When automobile is braked under normal traveling and state of rolling backward, straight trough cannot realize the great heat radiation effect of multi-operating mode braking.
Summary of the invention
In order to solve the technical problem existed in background technique, the present invention proposes a kind of heat-dissipation type disc brake pad, this brake block can carry out radiating and cooling equably, can discharge dust and rainwater easily, and has good radiating effect under multi-operating mode braking.
A kind of heat-dissipation type disc brake pad that the present invention proposes, comprise tinsel and brake pad, be provided with thermal-protective coating between described tinsel and described brake pad and three fits in aggregates, described brake pad is provided with the first arc-shaped groove group and the second arc-shaped groove group towards brake disc one side; Arc-shaped groove in described first arc-shaped groove group and described second arc-shaped groove group is Y type groove and bottom land is arc; In described first arc-shaped groove group, the fluting direction of arc-shaped groove is radially to external radiation centered by the brake disc center of circle, and arc protrusion direction is identical with brake disc sense of rotation; In described second arc-shaped groove group, the fluting direction of arc-shaped groove is radially to external radiation centered by the brake disc center of circle, and arc protrusion direction and brake disc direction of rotation.
Preferably, the arc-shaped groove in described first arc-shaped groove group reduces gradually from center to two side direction flute length.
Preferably, the arc-shaped groove in described first arc-shaped groove group reduces gradually from center to two side direction groove widths.
Preferably, the arc-shaped groove in described first arc-shaped groove group reduces gradually from center to two side direction groove depths.
Preferably, the arc-shaped groove in described second arc-shaped groove group reduces gradually from center to two side direction flute length.
Preferably, the arc-shaped groove in described second arc-shaped groove group reduces gradually from center to two side direction groove widths.
Preferably, the arc-shaped groove in described second arc-shaped groove group reduces gradually from center to two side direction groove depths.
Preferably, in described first arc-shaped groove group, the two ends of arc-shaped groove extend to the edge of described brake pad.
Preferably, in described second arc-shaped groove group, the two ends of arc-shaped groove extend to the edge of described brake pad.
In the present invention, this heat-dissipation type disc brake pad achieves has good radiating effect under multi-operating mode braking: when braking under normal travelling state, air enters the arc-shaped groove of the first arc-shaped groove group along direction of slotting in the first arc-shaped groove group, and discharge from arc-shaped groove in eddy current shape with brake disc motion, air fluxion strap car is because of the heat brought that brakes, its radiating effect and cooling-down effect are good all the time, because in the force direction between brake disc with brake pad and the first arc-shaped groove group, arc-shaped groove direction is consistent, the dust produced in rainwater and brake process is more easily arcuately slotted discharge, make brake block performance more stable, when state of rolling backward is braked, air enters the arc-shaped groove of the second arc-shaped groove group along direction of slotting in the second arc-shaped groove group, and discharge from arc-shaped groove in eddy current shape with brake disc motion, air fluxion strap car is because of the heat brought that brakes, its radiating effect and cooling-down effect are good all the time, because in the force direction between brake disc with brake pad and the second arc-shaped groove group, arc-shaped groove direction is consistent, the dust produced in rainwater and brake process is more easily arcuately slotted discharge, makes brake block performance more stable, like this, by arranging the first curve bath group and the second curve bath group, automobile normal travel and brake under state of rolling backward time radiating and cooling respond well, thus achieve, under multi-operating mode braking, there is good radiating effect, first arc-shaped groove combines arc-shaped groove in the second arc-shaped groove group and adopts Y type groove and bottom land is the design of arc, has gathered the advantage of U-type groove and V-type groove, is conducive to the discharge of the Homogeneouslly-radiating of brake block, cooling and dust.
