Using more break at present is drum brake and disk type braker.The form of drum brake has two kinds of internal tensional type and external beam formulas, the working principle of internal tensional type drum brake is: when being positioned at brake drum and having brake shoe at one end to be subjected to motivator, can outwards rotate around the fulcrum of its other end, be pressed against circle in the brake drum and on, produce friction torque, realize braking.The major defect of drum brake is that braking force and input power are disproportionate, is difficult to control, is easy to occur locking phenomenon.Disk type braker mainly is that the brake disc of working surface is formed by brake calipers, two friction plates with the end face, and brake disc is between two friction plates, and two friction plates are with respect to the brake disc symmetric arrangement.The working principle of disk type braker is: by brake calipers friction plate is contacted with brake disc, increase and the positive pressure that discharges friction plate and brake disc realizes braking and discharges braking.All there are the limited narrow limitation of braking moment in drum brake and disk type braker, and must apply external force by the outer energy and just can make its braking, and the speed that is braked is big more, and the external force that need offer break is big more, and promptly power also increases thereupon.
Above-mentioned two kinds of breaks are friction brake, the invention provides a kind of novel friction brake, need not initiative brake.
(3) summary of the invention
The object of the present invention is to provide a kind of type Wedge brake simple in structure, as to need not initiative brake, the saving energy that has.
The object of the present invention is achieved like this:
Type Wedge brake of the present invention comprises the support body that is arranged at outside the braking hub, described support body is positive 2n limit shape, n=2-4 wherein, a cover respectively is set by type wedge and the brake component formed of the damping energy storage apparatus of correspondence with it on a pair of adjacent edge in support body and their relative edges separately.The position corresponding with the type wedge is provided with T type groove on support body, is provided with solenoid valve between adjacent two type wedges outside support body, is connected with push rod at the solenoid valve output terminal, slided in T type groove by push rod repulsive-type maglev wedge.Push rod and support body adopt hole-axle to be slidingly connected its action of electromagnetic valve.
The present invention can also comprise:
1, described n=3, promptly described support body is a regular hexagon.
2, described damping energy storage apparatus is a groove type variable cross section hydraulic damping accumulating mechanism.
3, described damping energy storage apparatus is a spring damping accumulating mechanism.
4, the sectional shape of described type wedge is a right-angled trapezium, and the face at its right angle side place is a mating face, and the face at hypotenuse place is a braking surface.
5, the sectional shape of described push rod head is an isosceles trapezoid, the face repulsive-type maglev wedge at its waist place, and push rod can slide along the groove on the support body.
During braking, the solenoid valve outage, make the push rod that is connected with the solenoid valve output terminal slide along its axis, the repulsive-type maglev wedge contacts with the braking hub, the rotation of braking hub is done equidirectional slip by frictional force drive type wedge at the support body inwall, makes that type wedge and support body and braking hub are more and more tighter, simultaneous type wedge compression damping energy storage apparatus, when the accumulation of energy sum of frictional work and damping energy storage apparatus equates with the kinetic energy that is braked axle system, realize braking.After realizing braking, the damping energy storage apparatus discharges accumulation of energy makes the type wedge return original position.The speed of damping energy storage apparatus remission form wedge avoids break the phenomenon (being locking phenomenon) of moment braking to occur, in addition, need the very big power of lifting after the type wedge is clamped, the damping accumulating mechanism is born the most of or whole of the power of lifting, thereby the type wedge of making is return original position.The damping accumulating mechanism has two kinds of schemes: a kind of is groove type variable cross section hydraulic damping accumulating mechanism, and another kind is a spring damping accumulating mechanism.Can realize length control by regulating the parameter size and the Changing Pattern of damping energy storage apparatus to period of braking.The type wedge is arranged to symmetric form in pairs, and the damping energy storage apparatus is arranged symmetrically in type wedge both sides, and the braking that can realize braking the hub both direction also can be designed as unidirectional braking.Two point-symmetric type wedges are braked simultaneously, make the brake hub axle not bear moment of flexure.
Its working principle is: this type Wedge brake is to utilize the type wedge to contact with the braking hub to produce frictional force, braking hub drive type wedge motion under the effect of frictional force, make between type wedge and support body and the braking hub more and more tighter, absorb the kinetic energy that is braked hub by friction working, reach the purpose of braking with the principle of kinetic energy counter.
Its meaning is: obtain bigger braking force under the small construction situation, braking force (moment) increases and increases along with the kinetic energy that is braked.Period of braking prolongs along with the increase of damping.Owing to removed brake structure initiatively,, saved the energy so this type Wedge brake is simple in structure.Can be used for the braking of the high-power transmission of boats and ships etc., also can be used for the braking of small-power transmissions such as automobile.
