Description
Technical field
It the utility model is related to self cooled brake fluid pressure tongs technology field, and in particular to a kind of self cooled brake fluid pressure
Pincers.
Background technology
Self cooled brake fluid pressing tongs is the brake apparatus of automobile, the brake used in automobile be nearly all it is frictional,
Two major class of drum-type and disc type can be divided into.Rotate element in drum type brake friction pair is brake drum, its working surface is cylinder
Face；The rotate element of disk brake is then rotating brake disc, using end face as working surface.
Self cooled brake fluid pressing tongs refers to produce the power for hindering vehicle movement or movement tendency（Brake force）Component, its
In also include auxiliary braking system in retarding device.
Drum brake is all different according to its structure, and is divided into：Two-way self energizing effort shoe brake, double-collar and shoe type braking
Device, leading trailing shoe brake, two trailing shoe brake.Its brake efficiency reduces successively, and minimum is disk brake；But braking effect
Stabilizability is to increase successively, disk brake highest.Also exactly because this reason, disk brake are commonly used.
But since dynamic boosting system must be added in order to improve its brake efficiency, make its cost higher, therefore low side car generally still makes
With drum-type after shroud.
For the equipment for allowing tire and ground to increase friction coefficient, drum-type and dish-style are broadly divided into, and use for parking
, fast indicating brake action of drum-type is big, but brake force declines soon after fever；Dish-style braking technology is big, and fast brake force is inadequate
Drum-type it is big, but after generating heat or better braking effect can be kept, and advanced disc brake has 6 brakes
Pump, can carry out braking well compared with fruit, so modern trolley is all to use disc brake.
In the prior art, disk brake generally includes：Caliper, brake disc and brake strip；Brake disc is fixed on
On the wheel of automobile, and can be with vehicle wheel rotation；Brake strip is arranged on the both sides of brake disc, and has between brake disc
Certain gap；After driver steps on brake, the hydraulic oil in caliper provides hydraulic coupling and promotes brake strip to step up
Brake disc so that brake strip rubs with brake disc, to reduce vehicle wheel rotational speed, and then allows car deceleration or stopping.
When hydraulic oil drives piston and friction plate with brake disc friction catch, hydraulic oil continuous high-pressure produces high caliper
Heat, existing brake fluid pressure oil can only be after end of braking, and partial reflux is cooled down to hydraulic pump, and cooling effect is poor, in heat
When measuring superelevation, braking effect is not only influenced, and deep fat has higher requirement with piston material in itself to caliper, especially
Continuous braking cannot in time be cooled down and easily broken down.
