Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
All features disclosed in this specification, or the step in disclosed all methods or process, except the speciality mutually repelled and/or step, all can combine by any way, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object, namely, unless specifically stated otherwise, an embodiment in a series of equivalence of each feature or similar characteristics.
As shown in Figure 1, the present invention is used for the electro-magnetic braking device of small rail car, it comprises the friction head 1 directly producing friction catch, the push rod 2 of transmitting thrust, suction is produced and the electromagnet 5 driving push rod 2 to move after energising, for electromagnet 5 provides the power-supply controller of electric 8 of electric energy and the spring assembly 6 for generation of pressure, described power-supply controller of electric 8 is connected with electromagnet 5 circuit, power-supply controller of electric 8 provides electric energy for electromagnet 5, electromagnet 5 is located at the periphery of push rod 2, electromagnetic induction is produced after electromagnet 5 is energized, push rod 2 is driven to move, friction head 1 is located at one end of push rod 2, described friction head 1 is fixed with push rod 2 bolt, other one end of push rod 2 is located at by spring assembly 6.
Spring assembly 6 inside is provided with spring along direction, push rod 2 medial axis, will produce elastic strain when spring is compressed, and then promotion push rod moves forward; In order to most suitable braking friction can be ensured, the end of spring assembly 6 be also provided with regulate friction head 1 and by rubbing surface between the controlling mechanism 7 of stopping distance, one end and spring assembly 6 screw thread of described controlling mechanism 7 are fixed, the other end is screw thread rotation promote-side, can avoid the firmly excessive loss to being brought by rubbing surface 9 by regulating in advance of controlling mechanism; Described controlling mechanism 7, spring assembly 6 and friction head 1 are positioned on same medial axis.
In order to whole device is fixedly mounted, outside electromagnet 5, being provided with the housing 4 for installing, installing on a mounting board by housing; In order to ensure the moving direction of push rod 2, avoid the existence of deviation and error, be also provided with the guide sleeve 3 led for push rod 2 in the outside of described push rod 2, one end and the housing 4 of described guide sleeve 3 connect and fix.
Wherein, power-supply controller of electric, described power-supply controller of electric 8 is the magnetic vibrator that its interior loop is powered after silicon controlled rectifier by single phase alternating current power supply, is the product that market is common, RS-232 and RS-485 code can be sent, with computer and middle control, electromagnet is controlled.The coil of magnetic vibrator is powered after silicon controlled rectifier by single phase alternating current power supply, when controllable silicon is triggered conducting at the positive half cycle of Ac, coil passes through pulsating current, electromagnet just produces pulse-electromagnetic force, by means of the elasticity of spring assembly contained spring, thus push rod can be travelled forward, power supply controllable silicon when negative half period bears backward voltage and turns off, the heavy no current of coil passes through, electromagnetic force disappears, push rod is return, and like this after circulation, push rod just can move reciprocatingly with the frequency of alternating voltage.
Workflow of the present invention:
When small rail car needs to brake, controlling mechanism 7 realizes the gap regulating friction head and rubbing surface, for ensureing most suitable braking friction; Be in off-position by the electrical system control power-supply controller of electric 8 in power-supply controller of electric 8, exerted pressure by spring assembly 6 pairs of push rods 2, friction head 1 to be released through push rod 2 and is fitted with by rubbing surface by pressure, and the positive pressure of generation forms friction brake force; When small rail car needs to walk, "on" position is in by the electrical system control power-supply controller of electric 8 in power-supply controller of electric 8, electromagnet 5 will produce electromagnetic induction and form the suction-combining force after being energized, friction head 1 sucks back through push rod 2 by the suction-combining force produced by electromagnet 5, friction head 1 is made to leave by rubbing surface, release braking function.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
