Description
Technical field
The utility model relates to braking device technical field, particularly relates to a kind of disk type braker.The utility model also relates to a kind of automobile.
Background technique
Break is the one integral in vehicle, and it, for realizing the braking of vehicle, controls the travelling speed of vehicle with this, ensure the Security of vehicle with this.Along with the increase day by day with vehicle density that develops rapidly of highway industry, the requirement of people to the Security of break, reliability is more and more higher, and reliable break is smooth and easy to guarantee road traffic, ensure the person and vehicle safety, safeguard that civil order is stablized significant.
Break relatively more conventional in conventional art comprises disk type braker, drum brake etc., disk type braker realizes braking by brake disc, and the requirement of brake disc is that size is little, Braking efficiency is high, has higher high-temperature capability and higher thermal conductivity, and there are certain strength and stiffness, the noise making friction surface produce as far as possible with this does not occur to resonate and has the performance of attenuation vibration.
Brake disc thickness difference refers to that the thickness of brake disc along the circumferential direction changes.Brake disc thickness missionary society causes contact skewness and braking force equivalent redius to change.Simultaneously the varied in thickness of brake disc also can the piston of forced brake wheel cylinder move axially, and causes the fluctuation of retardation pressure.Test shows, under certain vehicle condition, the thickness of 15 μm is poor, careful driver just can feel brake judder, so the working surface of brake disc should be smooth, both side surface parallelism should be less than 8um, card total run-out is less than 0.03mm, if end face run-out amount is large, will pedal vibration be evoked, stroke is strengthened.
In braking process, brake disc temperature raises, and can cause brake disc buckling deformation, and the thickness increasing brake disc is poor.Even if the shape of brake disc does not have error, the relative velocity due to outer ring is greater than the relative velocity of inner ring, along with the continuity of braking, can produce a torrid zone in outer ring.Research shows, when speed exceedes certain critical velocity (such as 95km/h), the torrid zone can develop into focus one by one.The temperature of hot spot region reaches as high as 800 DEG C, reaches as high as 300 ~ 600 DEG C with the temperature difference in other places.It is poor that the temperature difference of 250 DEG C can produce the brake disc thickness of 10 μm.Consequent thickness difference can be recovered after the cooling period, and the shake caused thus is called heat shake or transient state shake.Meanwhile, overheated is the main cause causing brake heat fatigue ruption, cause misfunctioning of brake.
Brake disc in conventional art can produce a large amount of frictional heats in braking process, causes disk type braker to occur expanding, then occurs Under Thermal Fatigue Damage, cause the problem that disk type braker lost efficacy.In addition, it is undesirable that above-mentioned expansion also can cause that the surperficial parallelism of brake disc and card are beated etc., thus cause disk type braker to produce larger brake judder and noise.
Therefore, the brake disc in conventional art, due to External Force Acting after foozle, assembly error, use, use in high temperature and wearing and tearing after using a period of time, easily produce the phenomenons such as brake judder, brake noise and premature failure.
