Description
Technical field
The present invention relates to automobile brake technical field, particularly relate to a kind of heat-dissipation type wear-resistant 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 frictional behaviour of brake block and heat dispersion are the key elements 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 wear-resistant brake pad, this brake block wear-resisting property is excellent, can carry out radiating and cooling equably, dust and rainwater can be discharged easily, and under multi-operating mode braking, there is good radiating effect.
A kind of heat-dissipation type wear-resistant brake pad that the present invention proposes, comprise tinsel and brake pad, fit between described tinsel and described brake pad in aggregates, the both sides of described brake pad are provided with buffering inclined-plane, and described brake pad is provided with miniature pit on the rubbing surface of brake disc; Described brake pad is provided with the first arc-shaped groove group and the second arc-shaped groove group on the rubbing surface of brake disc, in described first arc-shaped groove group, the arc protrusion direction of arc-shaped groove is identical with brake disc sense of rotation, the arc protrusion direction of arc-shaped groove and brake disc direction of rotation in described second arc-shaped groove group; In described first arc-shaped groove group, the groove depth of arc-shaped groove is greater than the groove depth of arc-shaped groove in described second arc-shaped groove group, and in described first arc-shaped groove group and described second arc-shaped groove group, the two ends of arc-shaped groove extend to the edge of described brake pad.
Preferably, described miniature pit is evenly distributed on described brake pad towards unslotted region on the rubbing surface of brake disc.
Preferably, the arc-shaped groove in described first arc-shaped groove group reduces all gradually from center to two side direction flute length, groove depth, groove width.
Preferably, the arc-shaped groove in described second arc-shaped groove group reduces all gradually from center to two side direction flute length, groove depth, groove width.
In the present invention, this heat-dissipation type wear-resistant brake pad is provided with buffering inclined-plane in the both sides of brake pad, therefore when automobile produces vibrations, sufficient buffer space is reserved with between the buffering inclined-plane of both sides and brake disc, thus effectively can avoid the collision between brake pad and brake disc, the working life of brake block can be extended, brake pad is provided with miniature pit towards the rubbing surface of brake disc, thus promotes the surface roughness of friction plate, promotes skin friction, simultaneously, under multi-operating mode braking, there is good radiating effect: 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, in first arc-shaped groove group, the groove depth of arc-shaped groove is greater than the design of the groove depth of arc-shaped groove in the second arc-shaped groove group, take into full account that in vehicle traveling, the normal brake request travelled is higher than the brake request of state of rolling backward, thus carry out specific aim layout, improve the combination property of brake block, in first arc-shaped groove group and the second arc-shaped groove group, the two ends of arc-shaped groove extend to the edge of brake pad, make the heat radiation of brake block and the dust velocity of discharge faster.
