Description
Technical field
The utility model is related to the technical fields of automobile brake, and in particular, to a kind of heat radiating type brake hubs and its
Brake executes assembly.
Background technology
Brake gear is by generating friction between brake block and wheel hub or disc, and by running car during friction
When kinetic energy be transformed into thermal energy consumption and fall, common brake gear has " drum brakes " and " disk type brake " two kinds of patterns, drum-type
Brake is two semi-circular brake blocks of installing inside wheel hub, utilizes " lever principle " that brake block is pushed to make brake block and wheel
It rouses inner faces contact and rubs, and disk type brake is then the brake for going to clamp with brake callipers control two panels brake block on wheel
Disc will produce friction when brake block clamps disc between the two.
For drum brakes：
When stepping on brake pedal, the force of foot can be such that the piston in master cylinder pushes brake fluid forward and in oil circuit
Middle generation pressure.Pressure is transmitted to the wheel cylinder piston of each wheel via brake fluid, and the piston of wheel cylinder pushes brake again
Vehicle piece is outside, and the inner face of brake block and brake rim is made to rub, and generates enough frictional force and go to reduce the rotating speed of wheel, with
Achieve the purpose that brake.
It has the disadvantages that：
(1) brake rim of drum brakes diameter after heated will increase, and the stroke for stepping on brake pedal is caused to increase, and hold
Brake easily occurs and reacts situation not as expected.Therefore it when driving the vehicle using drum brakes, to avoid continuously stopping as possible
Vehicle causes brake block to generate heat fading phenomenon because of high temperature；
(2) brake system reaction is slower, and the power of trampling of brake is less susceptible to control, and it is dynamic to be unfavorable for doing high-frequency brake
Make；
(3) construction complex parts are more, and braking gap must adjust so that repair is not easy.
For disk type brake：
When the brake pedal is applied, the piston in master cylinder can be pushed, and pressure is established in brake fluid line.Pressure
The piston of the wheel cylinder on brake callipers is transmitted to via brake fluid, the piston of wheel cylinder, can be outside after being under pressure
It moves and brake block is pushed to go to clamp brake disc so that brake block rubs with brake disc, to reduce vehicle wheel rotational speed, allows vapour well
Vehicle slows down or stops.
It has the disadvantages that：
(1) because the automatic brake of not no drum brakes tightly acts on, the brake weight of disk type brake is made compared with drum brakes to be low；
(2) friction area between the brake block and brake disc of disk type brake is small compared with drum brakes, makes the strength of brake
Also smaller；
(3) to improve above-mentioned disk type brake the shortcomings that, therefore need larger stampede power or oil pressure；It must thus use
The brake disc being relatively large in diameter, or the oil pressure of brake system is improved, to improve the strength of brake；
(4) lever brake is not easy to install, some trailing wheels are added one group of drum-type and stopped thus using the vehicle of disk type brake
The hand brake mechanism of vehicle；
(5) abrasion of brake block is larger, causes its replacement frequency higher.
In conclusion being all had at present in two kinds of brake forms of the drum brakes and disk type brake that use in automobile more
The shortcomings that, the braking quality for improving automobile is badly in need of a kind of brake that can take into account drum brakes and disk type brake advantage simultaneously
Assembly is executed, is of great significance to the braking quality reform of automobile.
