Description
Technical field
The present invention relates to braking automobile field, particularly relate to automotive drum type braking field, specifically, be a kind of band heat radiation
The double-piston drum type hydraulic brake in hole.
Background technology
Automotive brake (being commonly called as brake) is a kind of device for car deceleration, when driving to driving in automobile
The safety taking advantage of personnel and pedestrian plays vital effect.Along with the most progressive of science and technology and development, constantly pushing away of automobile
Wide and universal, the brake of existing automobile has had renewal several times and the replacement, according to the work of existing automotive brake
Principle substantially can be classified as two classes: the first is disk brake, is i.e. commonly called as disc brake；The second is drum brake, and
It is commonly called as drum brakes or drum is stopped.The braking effect of disk brake is high, perfect heat-dissipating, but its cost is high, and cost puts into big；
Drum brake with low cost, good braking effect, reliability is high, but the heat fade of drum brakes is obvious, in braking continuously
After producing high temperature, owing to heat can not be distributed by brake rim in time in time that close, cause brake rim and brake block continuous high temperature,
Frictional force drastically declines, thus, drum brake easily produces the situation of brake failure in long braking procedure；With
Time, existing drum brake part utilizes machinery cable wire to transmit brake force, owing to cable wire is under long pulling force
Effect can deform, and causes braking to be formed long, and braking ability weakens.
Summary of the invention
It is an object of the invention to provide the double-piston drum type hydraulic brake of a kind of band louvre, be used for solving existing
Drum brakes, in long brake process, cannot distribute in time owing to producing high temperature, and two cause brake heat fade strong, brake
Power weakens, the problem even resulting in brake failure.
The present invention is achieved through the following technical solutions:
A kind of double-piston drum type hydraulic brake of band louvre, including brake rim, be provided with in described brake rim brake block and
Rocker bearing, described brake block is connected with rocker bearing and is positioned at the side of brake rim, it is characterised in that described rocker bearing
Quantity is two pieces, and the two ends of described two pieces of rocker bearings are connected by two ram pots, and described brake rim is provided with multiple dissipating
Hot hole.
Preferably, described rocker bearing is provided with standing screw, described standing screw is provided with back-moving spring, described
Back-moving spring two ends are separately mounted on the standing screw on two pieces of rocker bearings.
Further preferably, the quantity of described back-moving spring is 2.
Further preferred, described ram pot includes cylinder and piston, and described cylinder is provided with hydraulic tube, described piston
A diameter of 15-18 millimeter.
Further preferred, described louvre is obliquely installed along brake rim direction of rotation, and the angle of inclination is 20-30 degree.
What deserves to be explained is, the angle of described inclination refers to brake rim outer surface place circumference and any one louvre central axis
Intersection point is as brake rim outer surface point of contact, through the tangent line of brake rim outer surface circumference and this louvre central shaft at described point of contact
The angle of line.
Further preferred, a diameter of 2-4 millimeter of described louvre.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention is provided with louvre on brake rim, it is possible to the high temperature produced in brake process is dispersed into sky timely
In gas, it is achieved the effect of brake rim cooling, thus slow down the heat fade of brake weight, improve the heat resistanceheat resistant Decay Rate of brake with reliable
Property.
(2) louvre that the present invention is arranged on brake rim has tilted certain angle, and inclines to the direction that brake rim rotates
Tiltedly, thus, brake rim is along with in wheel rotary course, it is possible to thrown away by the high-temperature gas in brake rim, and sucks new cold
Air is lowered the temperature.
(3) further, the present invention is in brake process, it is possible to the brake powder that will be produced by the louvre arranged
Get rid of, it is to avoid occur because brake powder too much causes brake weight to weaken the most malfunctioning situation, add safety.
(4) present invention employs the ram pot of double-piston as the transmission of brake weight and actuator, with machined steel hitch
Structure is compared, and has power transmission clear and definite, and active force is big, the advantage of failure rate is low.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1:
In the present embodiment, the hydraulic oil in the ram pot 5 of employing is provided by the hydraulic tube being connected with described ram pot 5, due to liquid
Pressure actuator is all to carry out action by hydraulic tube delivery hydraulic pressure oil, therefore, to those skilled in the art, and this
It is belonging to prior art, common knowledge, so not just being described in detail.
Shown in accompanying drawing 1-2, the double-piston drum type hydraulic brake of a kind of band louvre, including brake rim 1, described in stop
Being provided with brake block 2 and rocker bearing 3 in car drum 1, described brake block 2 is connected with rocker bearing 3 and is positioned at the one of brake rim 1
Side, it is characterised in that the quantity of described rocker bearing 3 is two pieces, two ram pots are passed through at the two ends of described two pieces of rocker bearings 3
5 connect, and described brake rim 1 is provided with multiple louvre 11.
Operation principle:
When driver tramples brake pedal, the hydraulic oil in brake system enters in ram pot 5, hydraulic pressure by effect
Under, the distance at ram pot 5 two ends is elongated, thus promotes the two ends inner surface movement to brake rim 1 of rocker bearing 3, until tightly
The inner surface of patch brake rim 1, produces brake weight, reaches the purpose of brake.In the rotary course of brake rim 1, along with brake weight
With the increase of time, the temperature of brake rim 1 sharply increases the most therewith, and brake rim 1 is by being obliquely installed multiple dissipating along direction of rotation
Heat is distributed by hot hole 11, thus realizes the effect lowering the temperature brake rim 1 and brake rubber block 2, thus promotes brake
Performance, reaches to strengthen brake weight, prevents the purpose of brake failure.
Embodiment 2:
For mechanism and the principle of the further description present invention, shown in accompanying drawing 1-2, on the basis of embodiment 1, institute
State and on rocker bearing 3, be provided with standing screw 7, described standing screw 7 is provided with back-moving spring 6, described back-moving spring 6 two ends
It is separately mounted on the standing screw 7 on two pieces of rocker bearings 3.
Further preferably, the quantity of described back-moving spring 6 is 2.
Further preferred, described ram pot 5 includes cylinder 51 and piston 52, and described cylinder 51 is provided with hydraulic tube,
A diameter of 16 millimeters of described piston 52.
Further preferred, described louvre 11 is obliquely installed along brake rim 1 direction of rotation, and the angle of inclination is 25 degree.
Operation principle:
When after driver's releasing of brake pedal, under the effect of spring 6, two pieces of rocker bearings 3 are mutually drawn close, and brake rubber block 2 departs from
The inner surface of brake rim 1, loses and the friction of brake rim 1 inner surface, and brake weight disappears.
The operation principle of remainder is identical with operation principle described in embodiment 1, repeats the most one by one at this.
The above, be only presently preferred embodiments of the present invention, and the present invention not does any pro forma restriction, every depends on
Any simple modification of being made above example according to the technical spirit of the present invention, equivalent variations, each fall within the protection of the present invention
Within the scope of.
