Abstract
The utility model discloses an electromagnetic brake device. The utility model is characterized in that an electromagnetic coil is arranged in a casing; a brake pressure plate, a rotating block and a fixing plate are arranged on the outer side of the casing; an output shaft of a motor passes through the brake pressure plate, the rotating block and the fixing plate; a spring is installed in the casing. The utility model overcomes the defects that at present, the manufacturing process of a rim brake structure is more complicated and the braking force of a brake handle is larger; therefore, electromagnetic brake does not need the force of a handle and the electromagnetic brake has portable operation, labor saving and sensitive control. The electromagnetic brake device releases, when power is switched on; the electromagnetic brake device brakes, when the power is switched off. The electromagnetic brake device is suitable for electric environmental protection vehicles and electric vehicles for disabled persons.
Description
Technical field:
The utility model relates to the technical field of electric environmental protection car, specifically a kind of electromagnetic brake device of electric environmental protection car.
Prior art:
The wheel rim brake was not all adopted and carry out skidding on drive motor before and after at present electric vehicle mostly adopted, and its shortcoming is, the rim structure manufacturing process is complicated, and brake haft braking force is bigger.
Summary of the invention:
The purpose of this utility model is to provide a kind of electromagnetic brake device, and it can make brake operation light, laborsaving.
To achieve these goals, the technical solution of the utility model is: a kind of electromagnetic brake device device, it mainly comprises housing, brake runner Coupling Shaft and motor, the output shaft that the part of brake runner Coupling Shaft is passed housing and motor is connected, it is characterized in that: electromagnetic coil is housed in housing, brake pressing plate, rotating block and fixed plate are housed outside housing, and the output shaft of motor passes brake pressing plate, rotating block and fixed plate, and spring also is housed in housing.
The utility model has solved the complicated and bigger shortcoming of brake haft braking force of present wheel rim brake structure manufacturing process, make electromagnetic brake not need handle firmly, operate light, laborsaving, control is sensitive, this electromagnetic brake energising promptly discharges, outage i.e. brake, and the most suitable electric environmental protection car of this electromagnetic brake device and electronic handicapped people's car use.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
The utility model mainly comprises housing 5, brake runner Coupling Shaft 1 and motor 14, the output shaft 11 that the part of brake runner Coupling Shaft 1 is passed housing 5 and motor is connected, it is different from prior art and is: electromagnetic coil 4 is housed in housing 5, iron core 3 is housed in electromagnetic coil 4 in the enforcement, brake pressing plate 7 is housed outside housing 5, rotating block 9 and fixed plate 12, the output shaft 11 of motor passes brake pressing plate 7, rotating block 9 and fixed plate 12, spring 6 also is housed in housing 5, present embodiment is equipped with iron core 3 in electromagnetic coil 4, the electromagnetic coil 4 that iron core 3 will be housed during installation is contained in the housing 5, in housing 5, put into spring 6 in equally distributed 6 circle hole grooves, the opening portion of housing 5 covers the pressing plate 7 that is used to brake, by equally distributed three mounting screws 8, to brake rotating block 9 and fixed plate 12 is installed in earlier on the housing 5, when brake runner Coupling Shaft 1 is installed on the motor output shaft and after a fastening screw trip bolt 10 is connected firmly, by equally distributed three mounting screws 8 fixed plate 12 and whole electromagnetic brake device are installed on the output shaft of drive motor 14 again, between the opening portion of pressing plate 7 and housing 5, leave the gap of 0.2～0.4mm, active force by spring 6 makes the two be held static equilibrium, and electromagnetic coil 4 outwards is connected with lighting outlet 2.
Dynamic process of the present utility model is: when imposing voltage by 2 pairs of electromagnetic brake devices of lighting outlet, electromagnetic coil 4 is switched on and is made iron core 3 produce electromagnetic forces, brake pressing plate 7 is inhaled by electromagnetic force and is applied, make between the opening portion of brake pressing plate 7 and electromagnetic brake housing 5 and lose the gap, produce the gap and make between brake pressing plate 7 and the brake rotating block 9, drive motor its motor output shaft 11 under the electric power effect carries out coaxial running with brake runner Coupling Shaft 1; When the voltage drop that imposes by 2 pairs of electromagnetic brake devices of lighting outlet is low to moderate zero, electromagnetic coil 4 cuts off the power supply and makes iron-core coil 3 lose electromagnetic force, between brake pressing plate 7 under the effect of spring 6 and brake rotating block 9, lose the gap and make brake brake pressing plate 7 push down brake rotating block 9, thereby rotating block 9 is braked, because of the mounting hole of brake rotating block 9 installation shaft with brake runner Coupling Shaft 1 is connected and fixed, the mounting hole of brake runner Coupling Shaft 1 one ends is installed on the motor output shaft 11, so rotor is braked simultaneously and shuts down, thus the electromagnetic brake of realization motor.
The utility model can be widely used in the braking maneuver of electric bicycle (electric four-wheel vehicle) drive motor, when the rotation (operation of similar autobicycle gasoline throttle) backward of manipulating handgrip cover, electromagnetic brake is switched on and is inhaled and apply brake pressing plate 7, and the rotating block 9 that motor coaxle is linked to each other can rotate with the running of drive motor; When manipulating handgrip overlaps forward rotary reset to minimum, electromagnetic brake outage and lose electromagnetic force, and discharge brake pressing plate 7 makes rotating block 9 be pushed down by brake pressing plates 7 and electric machine main shaft is braked shut down, thereby reaches the effect of electromagnetic brake.
