Abstract
The utility model relates to double brake cylinder brake shoes of an electromobile. The double brake cylinder brake shoes of the electromobile comprise a brake disk, spring pins, a first connecting block, a second connecting block, a brake cylinder, the first brake shoe and the second brake shoe, wherein the spring pins are installed on the brake disk, the fist connecting block is movably connected with the first brake shoe, the second connecting block is movably connected with the second brake shoe, the first connecting block and the second connecting block are respectively provided with a spring, the springs are connected with the spring pins, the brake cylinder is installed between the first brake shoe and the second brake shoe, and a piston rod stretches out of the brake cylinder. The double brake cylinder brake shoes of the electromobile are simple in structure, convenient to use and install, easy to operate, low in cost, convenient to maintain, safe and reliable and are used for enhancing the braking performance of the brake shoes in the running of the electromobile so as to achieve normal running and avoid accidents.
Description
Technical field
The utility model relates to electric motor car manufacturing technology field, is specifically related to the two brake cylinder brake shoes of a kind of electric motor car.
Background technique
Brake shoe is the some of electric motor car drum-type brake system, and when cardinal principle is brake, the intratympanic two pairs of half-moon-shaped brake shoes of break open, and make it be adjacent to break tympanum inwall, thereby produces the rotation that friction stops wheel.At present, what the mode that the brake shoe brake structure opens adopted is mechanical type, and the rotating shaft working surface of this structure easily weares and teares, and makes the brake shoe amount of opening reduce, and has directly affected the skidding effect of electric motor car, to the user, brings loss.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of braking of travelling in electric motor car for strengthening brake shoe, the two brake cylinder brake shoes of the purpose electric motor car that travels, avoids accident to occur to reach normally.
For addressing the above problem, the utility model adopts following technological scheme:
The two brake cylinder brake shoes of a kind of electric motor car of the utility model, comprise brake disc, spring pin, the first contiguous block, the second contiguous block, brake cylinder, first brake hoof and the second brake shoe, described spring pin is arranged on brake disc, described the first contiguous block and first brake hoof are actively coupled, described the second contiguous block and the second brake shoe are actively coupled, be equipped with spring on described the first contiguous block and the second contiguous block, described spring is connected with spring pin, described brake cylinder is arranged between first brake hoof and the second brake shoe, be extended with piston rod on described brake cylinder.
As preferred technological scheme, be equipped with groove on described first brake hoof and the second brake shoe, described piston rod and groove offset.
As preferred technological scheme, described spring pin adopts the mode of welding to be fixedly connected with brake disc.
The beneficial effect of the two brake cylinder brake shoes of a kind of electric motor car of the utility model is: simple in structure, use, easy for installation, simple to operate, cost is low, easy to maintenance, for strengthening the braking that brake shoe travels in electric motor car, the purpose of travelling, avoid accident to occur to reach normally, safe and reliable.
The accompanying drawing explanation
The structural representation that Fig. 1 is the two brake cylinder brake shoes of a kind of electric motor car of the utility model.
Embodiment
Consult the two brake cylinder brake shoes of a kind of electric motor car shown in Fig. 1, comprise brake disc 1, spring pin 2, the first contiguous block 3, the second contiguous block 4, brake cylinder 5, first brake hoof 6 and the second brake shoe 7, described spring pin 2 is arranged on brake disc 1, described the first contiguous block 3 is actively coupled with first brake hoof 6, described the second contiguous block 4 and the second brake shoe 7 are actively coupled, be equipped with spring 8 on described the first contiguous block 3 and the second contiguous block 4, described spring 8 is connected with spring pin 2, described brake cylinder 5 is arranged between first brake hoof 6 and the second brake shoe 7, be extended with piston rod 9 on described brake cylinder 5.
Be equipped with groove 10 on described first brake hoof 6 and the second brake shoe 7, described piston rod 9 offsets with groove 10.
Described spring pin 2 adopts the mode of welding to be fixedly connected with brake disc 1.
Further, the brake shoe braking is controlled by symmetrically arranged two groups of brake cylinders, when vehicle brake is braked, brake cylinder left and right piston rod outwards advances, first brake hoof and the second brake shoe that drive offsets outwards open, and the sturdy break tympanum inwall of separately establishing reaches the skidding of vehicle.While cancelling braking, brake cylinder left and right piston rod back resetting, the first brake hoof offseted on piston rod and the second brake shoe, under acting force of the spring, are got back to original position, the control system connection of brake cylinder and electric motor car for together with, be convenient to the control of driver.
The beneficial effect of the two brake cylinder brake shoes of a kind of electric motor car of the utility model is: the utility model is simple in structure, use, easy for installation, simple to operate, cost is low, easy to maintenance, for strengthening the braking that brake shoe travels in electric motor car, the purpose of travelling, avoid accident to occur to reach normally, safe and reliable.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
