Description
Technical field
The utility model belongs to technical field of automobile parts, is specifically related to a kind of automobile brake drum with inner stiffener ring.
Background technique
Braking system is one of important composition system of automobile, and its secure context at automobile plays very important effect.At present, in truck field, widely used is to adopt traditional cast inblock drum brake.In prior art, comparatively typical break is friction brake, and the frictional heat producing while utilizing braking device work consumes the kinetic energy that vehicle has gradually, to reach the object that reduces car speed or parking.
At present, on truck extensive use be by grey cast iron cast-in-block drum brake.Grey cast iron is a kind of widely used friction material, but its intensity is low, fragility is large, causes the sidewall of brake drum must have larger thickness.When automobile heavy-load, while running at high speed, especially in the time of lower long slope or abrupt slope, because braking force is large, and continuous several times braking, brake drum inner wall temperature is sharply raise, internal-external temperature difference strengthens, and the mechanical behavior under high temperature of brake drum material also sharply declines.Brake drum wall thickness is thicker, and internal-external temperature difference is larger.Temperature difference stress adds that the mechanical behavior under high temperature of material worsens, often cause brake drum inwall to develop into be full of cracks by longitudinal fine fisssure, so that last brake drum cracking, for example automobile running, under severe road conditions or under heavily loaded vehicle condition, may lose efficacy because margin of safety deficiency causes cracking.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of automobile brake drum with inner stiffener ring, can play the object that improves automobile brake drum structural strength, and the utility model also has advantages of that volume is little, saves material simultaneously.
The main technical schemes that the utility model adopts is: a kind of automobile brake drum with inner stiffener ring, comprise brake drum drum body and friction layer, it is characterized in that: at least one stiffening ring vertical with described brake drum drum body axis is installed on the inner circumference of described brake drum drum body, described friction layer is arranged in brake drum drum body and stiffening ring is wrapped, the cross section of described stiffening ring is rectangle or trapezoidal, described stiffening ring has fracture, and fracture is filled by welding block and fixed.
The utility model also adopts following attached technological scheme:
Preferably, on the inwall of described brake drum drum body, there is wavy projection and sunk structure.
Preferably, described friction layer adopts antiwear cast iron alloy material, and described friction layer waters and casts from described brake drum drum body and stiffening ring is all wrapped.
The beneficial effect that adopts the utility model to bring is: improve automobile brake drum structural strength, also have advantages of that volume is little simultaneously, save material.
Brief description of the drawings
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the cross-sectional view of a kind of automobile brake drum with inner stiffener ring of the utility model;
Fig. 2 is the burst effect figure of a kind of automobile brake drum with inner stiffener ring of the utility model;
Fig. 3 is the structural representation of a kind of automobile brake drum with inner stiffener ring of the utility model;
Fig. 4 is the structural representation that the utility model is not installed brake drum drum body;
Fig. 5 is that the utility model stiffening ring is the cross-sectional view of trapezoidal automobile brake drum;
Fig. 6 is that the utility model stiffening ring is the burst effect figure of trapezoidal automobile brake drum.
The label that wherein component names is corresponding is as follows:
Brake drum drum body 1, friction layer 2, stiffening ring 3, fracture 4, welding block 5.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Embodiment 1:
As Figure 1-4, a kind of automobile brake drum with inner stiffener ring, comprise brake drum drum body 1 and friction layer 2, the stiffening ring 3 vertical with described brake drum drum body 1 axis is installed on the inner circumference of described brake drum drum body 1, the quantity of stiffening ring 3 can be 1, also can be 2, 3 or multiple, the tonnage of Main Basis truck and different quantity is set, for strengthening the structural strength of brake drum drum body 1, thereby realize the structural strength that improves automobile brake drum, described friction layer 2 is arranged in brake drum drum body 1 and stiffening ring 3 is wrapped, stiffening ring 3 is arranged on to the inside of brake drum drum body 1 herein, instead of outside, mainly contain so several advantages: first, can suitably reduce the outside dimension of friction layer 2, save accordingly the material of friction layer 2, reduce cost, the second, can suitably reduce the cylindrical of brake drum drum body 1, smaller volume.
In above-mentioned automobile brake drum, on the inwall of described brake drum drum body 1, there is wavy projection and sunk structure, improve the bonded area between inwall and the friction layer 2 of brake drum drum body 1, except improving the combination force between brake drum drum body 1 and friction layer 2, outside guarantee quality of product, also accelerate the heat radiation of brake drum drum body 1, not easy to crack, can effectively extend working life of brake drum drum body 1.
In above-mentioned automobile brake drum, described friction layer 2 adopts antiwear cast iron alloy material, described friction layer 2 waters and casts from described brake drum drum body 1 and stiffening ring 3 is all wrapped, the cross section of described stiffening ring 3 is rectangle, described stiffening ring 3 has fracture 4, and fracture 4 is filled and fixed by welding block 5.Herein, we first compress the fracture of stiffening ring 34, stiffening ring 3 is suitably dwindled, then pack in pre-processed brake drum drum body 1 and unclamp, stiffening ring 3 struts fracture 4 by the tension force of self to the inwall of brake drum drum body 1, then adopt welding at fracture 4 places, making fracture 4 places form a welding block 5 fixes stiffening ring 3, in this structure, pass through again casting, casting liquid flows in the space between stiffening ring 3 and brake drum drum body 1, stiffening ring 3 is fixed between friction layer 2 and brake drum drum body 1 firmly the most at last, improve the structural strength of automobile brake drum, also there is volume little simultaneously, save the advantage of material.
Embodiment 2:
As shown in Fig. 5-6, in above-mentioned automobile brake drum, described friction layer 2 adopts antiwear cast iron alloy material, described friction layer 2 waters and casts from described brake drum drum body 1 and stiffening ring 3 is all wrapped, the cross section of described stiffening ring 3 is trapezoidal, described stiffening ring 3 has fracture 4, and fracture 4 is filled and fixed by welding block 5.Herein, the outer ring of stiffening ring 3 is trapezoidal long limit, inner ring is trapezoidal minor face, the benefit of design is like this: we are in the time installing stiffening ring 3, after the fracture 4 of stiffening ring 3 compresses and dwindles, trapezoidal minor face is easily installed in the recess in brake drum drum body 1, and adopt at trapezoidal fracture 4 places while welding, more welding material flows in the space of brake drum drum body 1 and stiffening ring 3, more firm, the liquid of casting in addition flows in the space between stiffening ring 3 and brake drum drum body 1, owing to being trapezium structure, there is larger area of contact than rectangular shape, combination force after casting also will be larger, stiffening ring 3 is fixed between friction layer 2 and brake drum drum body 1 firmly, improve the structural strength of automobile brake drum, also there is volume little simultaneously, save the advantage of material.
The described specific embodiment of the utility model is only to the explanation for example of the utility model spirit.Every other various amendments that drawn according to the technical solution of the utility model by those skilled in the art or supplement or adopt similar mode of execution, within dropping on equally protection domain of the present utility model.
