Description
The present invention relates to a kind of braking method and device of moving object.
Existing braking method and device are by braking force source branch: can be divided into driving type braking (vapour braking, liquid braking, vacuum braking); The electromagnetic type braking; The braking of manpower formula.The driving type braking, drive air pump, oil pump, vacuum pump etc. with power source, drive cylinder, oil cylinder, vacuum reservoir etc. with certain pressed gas, liquid and vacuum (too air pressure) external force is provided, make to produce motion-impeding frictional force between break and the moving object (driving mechanism), moving object is braked.The electromagnetic type braking provides external force by electric power source; The braking of manpower formula provides external force by human body.Above-mentioned braking method and common characteristic of device are: for reaching the braking purpose, need one to overlap the device that external force is provided specially, as air pump, oil pump, vacuum pump; Devices such as cylinder, oil cylinder, vacuum reservoir.Electromagnetic type braking and the braking of manpower formula are subjected to certain restriction in the use, use existing driving type braking method and device, when object of which movement, for guaranteeing that braking device is in readiness for operation at any time, need consumes energy, as the automobile that adopts gas to brake, for guaranteeing driving safety, when descending, still to open motor, drive air pump, stock enough pressed gas, make the usefulness of braking to drive cylinder at any time, at this moment the fuel oil that motor consumed, its main purpose is not a towing motorcar, but for braking vehicle at any time.Though recently the stored energy brake new technology is arranged, the inertia energy that is braked object is stored, make the usefulness of regeneration traction, but still provide external force to brake by other power source.And the regenerative braking on the electric locomotive, resistive braking, they all change the motor on the electric locomotive into generator, with motion locomotive brake (deceleration), this kind method, though good braking effect during high speed, the low speed weak effect, then must with the supporting use of another set of power-absorption unit, could the regulation stopping distance in reach the braking purpose.Generally speaking, existing braking technology all needs the external force source that braking external force is provided, and just can reach the braking purpose.
The purpose of this invention is to provide braking method and device that a kind of inertial force with moving object itself is converted to the external force of this object of braking.

The inventive method is, referring to Fig. 1, establishes and its follower that can rotate simultaneously (2) at the revolving member (1) of moving object, establishes brake disc (3) in follower (2). During braking, under the power effect of operating physical force such as electromagnet (4), brake disc (6) in the one-level arrestment mechanism (5) compresses brake disc (3) with certain force (electromagnetic force), and by follower (2) revolving member (1) being produced corresponding resistance turns to moment of friction. In the present invention, moment of friction is turned in the resistance that the power such as one-level arrestment mechanism (5) dependence electromagnetism produce, its main purpose is not in order to realize braking, but for after compressing brake disc (3) when brake disc (6), in the situation that moving object is not braked, by the frictional force effect, brake disc produces certain rotation with follower, thereby drive one-level force-increasing mechanism (8) by the drive (7) in the one-level arrestment mechanism (5), so that the rotation inertia force of revolving member (1) is converted to the braking external force of two stage braking mechanism (9). Because the increase effect that force-increasing mechanism of the present invention has power, the brake force that is converted by inertia force increases through one-level force-increasing mechanism (8), then two stage braking mechanism (9) is to be several times as much as the braking external force of one-level arrestment mechanism, and by its corresponding follower revolving member (1) being produced certain resistance turns to moment of friction. Two stage braking mechanism (9) another main purpose except playing braking action is the braking external force that the inertia force that will not be overcome is converted to the next stage arrestment mechanism, drive secondary force-increasing mechanism (11) by its drive (13), the secondary force-increasing mechanism drives again three-stage brake mechanism (12), so that three-stage brake mechanism is again to be several times as much as the braking external force of two stage braking mechanism, by follower revolving member (1) being produced corresponding big resistance turns to moment of friction, reaches the purpose with the moving object braking. If through three-stage brake, still unrealized braking also can be set up reinforcement and arrestment mechanism, playing main braking action in arrestment mechanisms at different levels is afterbody, and the afterbody arrestment mechanism, no longer plays the conversion effect. When this invention was used for automobile or tractor braking, follower can be contained on the wheel shaft, then by brake axle, the wheel shaft rotation inertia force was converted to braking external force, passed to brake apparatus (device). To reach the prevention body movement. When being used for the flywheel braking, follower can be contained on the flywheel, then directly brakes flywheel.
In the method for the invention, to be provided with one-level boosting mechanism and dual unit actuation mechanism at least, mainly play the arrestment mechanism of conversion effect comprising one-level.
Comprise follower with the corresponding contrive equipment of the inventive method, arrestment mechanism, boosting mechanism, the braking when realizing the object back and forth movement, at arrestment mechanism, in establish unidirectional top (drawing) power apparatus.
Apparatus of the present invention are established dual unit actuation mechanism and one-level boosting mechanism at least, and first order arrestment mechanism is except that producing less braking force, and it mainly acts on is to make object inertial force can realize conversion.The later arrestment mechanism in the second level or the second level is when realizing the purpose of its braking, another main purpose is that the inertial force that will not be overcome is converted to subordinate's braking external force, and through the boosting mechanism reinforcement, what play main braking action in whole braking process is afterbody break (mechanism).
