Description
Technical field
The present invention is a kind of brake equipment, particularly a kind of mechanical energy in the motion process is changed into elastic energy by the mutual action between the parts, thereby realizes the mechanical damping formula resistance braking device of braking effect.
Background technology
The brake equipment that present facilities for transport and communication (as automobile) generally use is hub type brake or plate disc brake, and the principle of this type of drg all is that the mechanical kinetic energy in the motion is changed into heat energy by friction, thereby realizes the effect of braking.There is following shortcoming in existing drg: efficient is low when the chance emergency case needs emergency braking, and stopping distance is relatively large, has increased the incidence of accident; Frequent braking can make brake wheel and brake strip overheated, thereby causes brake efficiency to descend, and brings potential safety hazard; The overload of service braking system can make the life-span of brake wheel and brake strip shorten greatly, and use cost and maintenance load strengthen.
Summary of the invention
The objective of the invention is thereby invention is a kind of mechanical energy in the motion to be changed into the mechanical damping formula resistance braking device that elastic energy is realized braking effect by the mutual action between the parts in order to overcome the defective that existing brake equipment efficient is low, stopping distance is big, accident rate is high, service life is short.
The objective of the invention is to realize as follows: described mechanical damping formula resistance braking device, comprise internal axle sleeve, bottom bracket axle, outer shaft, press rods and U-shaped locating rack, the outside of internal axle sleeve along the radial radiation shape be provided with a plurality of flexure strips, inboard at bottom bracket axle, have a plurality of and the corresponding groove of flexure strip, the top card of flexure strip is embedded in the groove, is provided with a plurality of balls by bearing frame between bottom bracket axle and the outer shaft; The U-shaped locating rack be connected across outer shaft above, the inboard of U-shaped locating rack recess is provided with a locating dowel pin, accordingly have a positioning groove in the outside of outer shaft, locating dowel pin is plugged in the positioning groove, make outer shaft and U-shaped locating rack keep relative static, the outside of U-shaped locating rack recess is provided with press rods, and two ends of U-shaped locating rack are provided with the collar, and two collars lay respectively at the both sides of internal axle sleeve.
Good effect of the present invention is as follows: but the present invention's at high speed consumes inertia energy, improves brake efficiency, shortens stopping distance, effectively avoids safety misadventure or mitigation; Parts produce friction hardly when work, no dust emission, and the heat of generation is minimum; Structure is simple relatively, consumes for a short time, is easy to maintenance; When using, can make the steady deceleration of driving vehicle and not consume brake system as retarder.The present invention is applicable to transportation devices such as all kinds of automobiles, railway vehicle and aircrafts.

The specific embodiment
Shown in Figure 2 as Fig. 1, described mechanical damping formula resistance braking device, comprise internal axle sleeve 1, bottom bracket axle 2, outer shaft 3, press rods 4 and U-shaped locating rack 5, the outside of internal axle sleeve 1 along the radial radiation shape be provided with a plurality of flexure strips 6, inboard at bottom bracket axle 2, have a plurality of and flexure strip 6 corresponding grooves 7, the top card of flexure strip 6 is embedded in the groove 7, is provided with a plurality of balls 9 by bearing frame 8 between bottom bracket axle 2 and the outer shaft 3; U-shaped locating rack 5 be connected across outer shaft 3 above, the inboard of U-shaped locating rack 5 recesses is provided with a locating dowel pin 10, the corresponding positioning groove 11 that has in the outside of outer shaft 3, locating dowel pin 10 is plugged in the positioning groove 11, make outer shaft 3 keep relative static with U-shaped locating rack 5, the outside of U-shaped locating rack 5 recesses is provided with press rods 4, and two ends of U-shaped locating rack 5 are provided with the both sides that 12, two collars 12 of the collar lay respectively at internal axle sleeve 1.
During use, internal axle sleeve is fixed on the moving axis by pin, and the collar then is enclosed within on the moving axis, and the upper end of press rods is connected with pressure source, as hydraulic pressure, air pressure, electronic, manual.
Principle of work of the present invention is as follows: need braking or when slow, pressure source is exerted pressure to press rods, press rods is transmitted to pressure on the ball bearing of main shaft by outer shaft, ball and internal axle sleeve institute structure, makes ball bearing of main shaft and moving axis formation radial disbalance; Flexure strip on the internal axle sleeve is subjected to the downward pressure of ball bearing of main shaft when rotating, flexure strip is compressed by force, thereby moving axis is produced lock torque, by flexure strip compression and release repeatedly, makes kinetic energy change into elastic energy, realizes braking and slow effect; During brake off, press rods is lifted, and press rods institute applied pressure is released, and flexure strip is set back, and braking force disappears.
