Abstract
The utility model discloses a magnesium aluminum alloy brake bottom plate, which is applied in the field of automotive brake plates. The magnesium aluminum alloy brake bottom plate comprises an annular disc body. Brake shoe mounting holes are symmetrically formed on the annular disc body which is die-cast by a magnesium aluminum alloy. A brake shoe fixing base is locked at the brake shoe mounting holes. A through hole is formed in the brake shoe fixing base, and is concentric with one brake shoe mounting hole. A ferroalloy inner ring is arranged on a center hole of the annular disc body. The magnesium aluminum alloy brake bottom plate has the advantages of high performance of abrasive resistance, high temperature resistance and the like, good radiation effects and high braking performance, and the service life of a brake plate is prolonged.
Description
Technical field
The utility model relates to a kind of automobile brake plate technique field, especially a kind of magnalium braking bottom board.
Background technique
Brake system of car divides by type, mainly is divided into two kinds of drum brake and disc type brakes.Drum brake is utilized brake shoe extruding brake drum to produce braking force and is stopped, and causes reasons such as moment brake failure, heat radiation be bad behind bad owing to its braking force smoothness, the wet water easily, and it is technological to belong to backwardnesss.
Present main flow braking system is a shoe brake, mainly is made up of a pair of brake shoe, and wherein brake shoe and wheel connect; Brake shoe is braked with air pressure; When driver's pin was stepped on brake petal, pedal promoted braking overall pump and promotes gas entering wheel cylinder, the gas pressure that transported by tracheae of wheel cylinder; The promotion brake shoe is pressed to brake shoe and is rubbed, and produces braking force and stops to force wheel.In said system, braking bottom board is a vitals, and at present great majority all are fabricated from iron, and in practical application, have following problem, 1, complex process, wear no resistance, and wear intensity is higher; 2, radiating effect is bad, steps on repeatedly will cause brake shoe to be heated after the braking and its temperature is risen to more than 350 degree, causes friction factor to reduce, and stopping distance prolongs, braking failure, and accident takes place frequently; 3, quality is big, has increased the fuel consumption of car load, and Cast Iron Surface very easily gets rusty, in a word cast iron braking bottom board short, poor stop in working life.
The model utility content
The utility model provides a kind of magnalium braking bottom board for problems such as solving existing cast iron braking bottom board complex process, wear no resistance, radiating effect is bad, quality is big.
In order to reach above-mentioned purpose of design, the technological scheme that the utility model adopts is following:
A kind of magnalium braking bottom board; Comprise the circular disk body; Be arranged with the brake shoe mounting hole on the circular disk body that forms by magnalium die casting; The locking of brake shoe fixed base is at brake shoe mounting hole place, and said brake shoe fixed base is provided with through hole, a through hole and a brake shoe mounting hole concentric; The center hole of said circular disk body is provided with the ferro-alloy inner ring.
Said ferro-alloy inner ring is fixed on the center hole outer of circular disk body.
Be provided with iron alloy liner bushing in the said through hole.
The beneficial effect of the described magnalium braking bottom board of the utility model is: adopt integral die-cast technology to process; Improved the performance such as wear-resisting, high temperature resistant of keep plate greatly; Radiating effect is good, more than four times, has prolonged the working life of keep plate than cast iron keep plate rapid heat dissipation; Braking ability is higher than traditional cast iron keep plate far away, and the friction life-span is more than five times of traditional cast iron keep plate.
Quality is 40% of an existing cast iron keep plate, has reduced the fuel consumption of car load.
The described keep plate of the utility model can be widely used in all kinds heavy-duty car.
The circular disk body that adopts magnalium to process, weight alleviates greatly, thereby has reduced the fuel consumption of car load; And on center hole, set up the ferro-alloy inner ring, and improved the technology of braking bottom board, performance such as wear-resisting, high temperature resistant, prolonged the working life of braking bottom board, strengthened the braking safety of car load.

Embodiment
Below in conjunction with accompanying drawing the optimum implementation of the utility model is done further detailed description.
Shown in Fig. 1-2; The described magnalium braking bottom board of the utility model embodiment; Comprise circular disk body 1, be arranged with brake shoe mounting hole 3 on the circular disk body 1,2 lockings of brake shoe fixed base are at brake shoe mounting hole 3 places; Said brake shoe fixed base 2 is provided with through hole 4, through hole 4 and a brake shoe mounting hole 3 concentrics; Described circular disk body 1 is to be formed by magnalium die casting on the whole, and the center hole of circular disk body 1 is provided with ferro-alloy inner ring 5.
Said ferro-alloy inner ring 5 is fixed on the center hole outer of circular disk body 1.
Be provided with iron alloy liner bushing 6 in the said through hole 4.
The preferred embodiment of this embodiment the utility model can not limit the utility model, and concrete each item rights protection scope is defined by the claims.
