Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment and join
According to attached drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hair
Bright range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid this is unnecessarily obscured
The concept of invention.
Specific embodiment: in conjunction with shown in Fig. 1-5, including brake 1；1 side of brake is provided with fixing seat
101；The 101 top border of fixing seat is evenly arranged with multiple groups location hole 102；Between described 101 one end of fixing seat and vehicle bridge
It is connected by screw bolts；4 other side of brake shoe is provided with brake drum 2；The 1 inside two sides of brake are symmetrically arranged with braking
Device 3；The relatively narrow one end of 2 upper diameter of brake drum is mounting surface 201；201 top of mounting surface is evenly arranged with more
Group mounting hole 202；The 2 top border of brake drum is evenly arranged with arc groove 203；The brake apparatus 3 includes brake shoe
4, air bag 301, fixed frame 302, reset lever 303, extension spring 304 and support shaft 305；3 two sides of brake apparatus are symmetrical
It is provided with the brake shoe 4, the air bag 301, the fixed frame 302, the extension spring 304 and the support shaft 305；Institute
It states and is connected by screw bolts between support shaft 305 and the fixing seat 101；Between described 4 one end of brake shoe and the support shaft 305
It is connected using shaft；The air bag 301 between the fixed frame 302 and fixing seat 101 by being connected by screw bolts；The reset
303 both ends of pull rod are used with the brake shoe 4 by the extension spring 304 be clamped respectively；The brake shoe 4 includes lining
401, brake liner plate 402 and arc bracket 403；The brake liner plate 402 setting with 403 outside of arc bracket and and its
Using clamping；The setting of lining 401 is connect in 402 outside of brake liner plate and with its screw；On the lining 401
Portion's circumferential direction is provided with two groups of arc-shaped slots 404.
In use, step 1, as shown in Figure 1, the biggish automobile of load-carrying can be selected when user selects mode of braking
Drum brakes is because drum brakes has the function of that automatic brake is tight, and used oil pressure is smaller, and processing and manufacturing at
This is also cheaper, but existing drum brakes is when carrying out emergency braking, or there is the hypodynamic reason of braking,
For this purpose, user can select a kind of double brake wheel cylinder brake shoe of this money, thus the presence to solve the above problems；
Step 2, as shown in Figure 2-5, when user drives, an emergency situation is encountered when being braked, and only needs this moment
It exerts oneself brake pedal, brake pedal will drive brake 1 by air pump, this is engraved in inside brake 1
Air bag 301 starts to inflate rapidly, and starts to push arc bracket 403, so that arc bracket 403 is further driven to
Brake liner plate 402 and lining 401 are in contact with brake drum 2, and moving out with arc bracket 403 this moment, can be into one
Step drive extension spring 304 stretched, this moment lining 401 will start with 2 phase friction of brake drum, thus generate braking effect
Fruit, lining 401 and 2 gap of brake drum are smaller when emergency braking in order to prevent, poor so as to cause heat dissipation effect, easily occur
The case where brake fade, is uniformly provided with arc-shaped slot 404 on the top of lining 401 thus, is made by arc-shaped slot 404 to enable
Piece 401 is radiated in time, and the outer wall of brake drum 2 is evenly arranged with arc groove 203, to improve brake drum 2
The heat dissipation effect of body, and the inside of brake 1 arranges two groups of brake apparatus 3, to improve the braking effect of brake 1 itself
Fruit, slows down the braking distance of automobile, to substantially increase the traffic safety of automobile itself；
Step 3, as shown in figure 4, loosen the brake this moment after user no longer brakes, and then air bag 301 starts to shrink,
And brake-shoe will realize reset under the action of extension spring 304 this moment, so that it is detached from the braking between brake drum 2, it is whole
Body structure is simple, convenient and practical.
It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention
Principle, but not to limit the present invention.Therefore, that is done without departing from the spirit and scope of the present invention is any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.In addition, appended claims purport of the present invention
Covering the whole variations fallen into attached claim scope and boundary or this range and the equivalent form on boundary and is repairing
Change example.
