Abstract
The utility model relates to the technical field of car brake pads, in particular to a car brake pad nodular cast iron steel back with oblique nails. The car brake pad nodular cast iron steel back comprises a plate body (1) with a steel back structure and is characterized in that two blind holes (3) are formed in the plate body (1), two hydraulic ejector pins of a car brake system are pressed into the two blind holes (3) during braking, and 20-80 oblique diamond-shaped nails adhered to a friction block are evenly distributed at the back of the plate body (1). Due to the fact that the oblique nails are evenly distributed on the back of the steel back, the combination and adhesion between the friction block and the steel back can be enhanced, the friction block is firmly integrated with the steel back, moments can be transmitted effectively, and flexible, safe and reliable braking is achieved. In addition, due to the fact that the steel back is made of nodular cast iron, the steel back is wear resistant and low in manufacturing cost, high temperature cannot be generated easily evenly under high-frequency friction, and the harmful gas cannot be easily generated by friction material.
Description
Technical field
The utility model relates to automobile disc brake pad technical field technical field, is specifically related to a kind of automobile brake sheet spheroidal graphite cast iron steel backing.
Background technique
In the brake system of automobile, brake block is the most key breaking piece, and the quality of all braking effects is all that brake block plays a decisive role.Brake block is generally made up of steel backing, bonding thermal-protective coating and brake pad, and steel backing has been mainly the effect of fixed support brake pad in automobile brake sheet, produces frictional force by the brake block fixing and with pressurization between the brake disc of vehicle wheel rotation, reaches the object of brake.Frictional force is that brake pad and brake disc friction produce, frictional force stops vehicle wheel rotation and brakes, and the reaction force of frictional force makes to produce between brake pad and steel backing moment of torsion, this moment of torsion was both delivered on vehicle frame by steel backing, also to destroy combination between brake pad and steel backing bonding simultaneously, cause between brake pad and steel backing and easily come off, so the combination bonding force how steel backing structurally improves between brake pad is the important topic that steel backing is manufactured.That right angle is cylindrical and be combined bonding nail in prior art on steel backing with brake pad, the disadvantage that the columniform nail in this right angle exists: in the time of brake, brake pad can be to the very large moment of steel backing transmission, because nail is cylindrical, so easily skid between brake pad and steel backing, because easily skid, the one, the efficiency of carry-over moment is poor, and the 2nd, between brake pad and steel backing, easily come off.Also have existing steel backing of vehicle brake block all to adopt slab or cast steel to make, adopt slab to make, the punch process that can adopt as thin in slab, but because the thin easily distortion under high-frequency Environmental Conditions of slab; The punch process that cannot adopt as thick in slab, several ten nails on plate body can only adopt the method for welding to make, so very time-consuming.And adopt cast steel to make, and the one, wear no resistance, the 2nd, cost is high, and Normal Steel Casting in this way under friction, can produce high temperature, and at high temperature, friction material easily produces harmful gas high-frequency not stopping.And the patent that in prior art, notification number is CN201851566U " a kind of brake block ", it by welding chain link fence on the bonding plane of Steel Backing Plate, again brake pad is bonded on chain link fence, but the intensity difference that bears shearing force between its steel backing and brake pad, easily cause brake pad in braking process to come off from steel backing, cause braking failure and cause accident to produce.
Summary of the invention
Easily come off from steel backing for the brake pad in brake block in prior art, the efficiency of carry-over moment is poor, and braking effect is undesirable, easily discharge the problems such as harmful gas, the efficiency of having invented a kind of carry-over moment is high, good braking effect, safe and reliable automobile brake sheet spheroidal graphite cast iron steel backing.
Above-mentioned goal of the invention is achieved through the following technical solutions:
An automobile brake sheet spheroidal graphite cast iron steel backing that is shaped with nail, comprises the plate body with steel back structure, and its main points are, 2 hydraulic top thick sticks that described plate body is provided with the brake system of automobile head into two blind holes wherein in the time of brake; The plate body back side is uniform be shaped with 20 ~ 80 with the inclination nail (2) of brake pad adhesive bond; Described inclination nail is rhombus inclination nail.
As preferably, described inclination nail and the angle at the plate body back side are 83 ° ~ 87 °.
As preferably, described inclination nail and the angle at the plate body back side are 85 °.
As preferably, be shaped with the automobile brake sheet spheroidal graphite cast iron steel backing that tilts to follow closely and made by spheroidal graphite cast iron.
The utility model compared with prior art tool has the following advantages:
Two blind holes that arrange on plate body of the present utility model, when brake, 2 of the brake system of automobile hydraulic top thick sticks head in two blind holes, safety and reliability when brake; The steel backing back side is uniform is shaped with 20 ~ 80 nails that tilt, tilt nail for rhombus and inclination, with the angle at the plate body back side be 83 ° ~ 87 °, because it tilts as barb, rhombus can increase the friction between brake pad, and it is bonding that therefore it can strengthen combination between brake pad and steel backing, make it become firm inseparable entirety, when break work, under the various twisting forces of various complex environments, effectively carry-over moment, brakes sensitiveer; In addition, it is made up of spheroidal graphite cast iron, thus not only wear-resisting, and also cost is low, even do not stop under friction high-frequency, be also difficult for producing high temperature, thereby friction material is also difficult for producing harmful gas.Therefore generally speaking, the utility model is simple in structure, reasonable in design, good braking effect, using process safety and reliability.
