Background technology
Brake gear produces friction by between brake facing and wheel hub or disc, and become thermal energy consumption to fall the kinetic energy of running car in the process of friction.
Early stage automobile generally uses band brake or shoe type brake, and brake is all positioned on automobile back wheel, by being mechanically connected on joystick or pedal.1904, Lei Nufu obtained the patent of front wheel brake.This brake, and to be arranged on A Jier car in 1909 afterwards by Alan improves in 2 years.After Ford proposed various interchangeable separation type brake bush in 1900, the various brake bush that can match with steel brake wheel or cast iron brake wheel are there are soon.1902, the Reynolds utility model brake wheel of standard, it had two brake shoes cutting with scissors connection, with a cam, two brake shoes is separated.From 1919, the people such as moral Wang De achieved a series of patent in the brake of hydraulic pressure auxiliary servo.Nineteen twenty, safer when the people such as Ben Dike are in order to brake, more steadily, in brake device for car, employ two servobrake.1906 Da Lake type brake feature with the present age brake principle the same, all manufacture collar plate shape.
Common are drum brakes, disk type brake, air heave type brakes, and namely common ABS antiblock device is the example using disk type brake, and general disk type brake is all compress at axial direction the object that brake facing reaches brake.
Summary of the invention
The purpose of this utility model is: for the defect of prior art, provides a kind of brake gear, and scheme of the present utility model makes brake facing be close to axle in radial direction, reaches the object of brake, to overcome the deficiencies in the prior art.
The technical solution of the utility model
A kind of brake gear, comprise turning cylinder, be provided with into oil discharge passage annular chamber cover on the rotating shaft and the line of centers of annular chamber overlap with the line of centers of turning cylinder, the inner ring of annular chamber is provided with passage, gap is formed between this annular chamber and turning cylinder, at least 2 brake facings are distributed in gap and the distance between center line of this brake facing distance turning cylinder is consistent, in the non-operative end of brake facing, piston is set, piston inserts annular chamber passage and stretches in the cavity of annular chamber, block one is provided with at the middle part of piston, block two is provided with in the bottom of passage, spring housing is on piston and coordinate with block one and block two, hydraulic oil is full of in the cavity of annular chamber.
In aforesaid a kind of brake gear, described brake facing is evenly distributed between annular chamber and turning cylinder and is formed in gap.
In aforesaid a kind of brake gear, described brake facing driving surface is circular configuration, and its radius size is consistent with the radius size of its corresponding turning cylinder.
In aforesaid a kind of brake gear, be provided with rubber ring to prevent the leakage of hydraulic oil at passage and piston space.
Owing to have employed technique scheme, compared with prior art, the utility model can brake in emergency situations, and be compress brake facing in different directions simultaneously, the meeting of stressed aspect evenly, and use fluid pressure type brake, the process making brake more steadily, safer, and radial system flowing mode is more reasonable, stable.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model when not braking;
Accompanying drawing 2 is the utility model structural representations when braking state.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
Embodiment of the present utility model: a kind of brake method, the method adopts at least 2 brake facings to be evenly distributed on around turning cylinder, when braking, brake facing moves relative to turning cylinder radial direction until contact with turning cylinder and rub thus realize braking the radial direction of turning cylinder.
Wherein realizing the method that brake facing is evenly distributed on turning cylinder is arrange an annular chamber, this annular chamber overlaps on the rotating shaft and the line of centers of annular chamber overlaps with the line of centers of turning cylinder, the inner ring of annular chamber is provided with passage, gap is formed between this this annular chamber and turning cylinder, at least 2 brake facings are evenly distributed in gap and the distance between center line of this brake facing distance turning cylinder is consistent, in the non-operative end of brake facing, piston is set, piston inserts annular chamber passage and stretches in the cavity of annular chamber, block one is provided with at the middle part of piston, block two is provided with in the bottom of passage, spring housing is on piston and coordinate with block one and block two, be provided with into oil discharge passage in annular chamber one end, realize being full of hydraulic oil in the cavity of annular chamber, this brake facing driving surface is circular configuration, its radius size is consistent with the radius size of its corresponding turning cylinder.
The concrete mode of operation of brake facing is: when needs brake, from entering oil discharge passage press-in hydraulic oil, hydraulic oil clamping piston, along with increasing of hydraulic oil, the pressure acting on upper piston area becomes large gradually, when more than a critical value, piston starts inwardly to move relative to the radial direction of turning cylinder, now brake facing is also along with piston radial motion, when brake facing with when being coupling tactile, start frictional heat, be that heat disappears thus makes axle rotation more and more slower by the transformation of energy of axle, along with hydraulic oil continue enter, the power that piston is subject to is increasing, thus push brake facing compression axis, the rotating speed of axle is finally made to lower, when not needing brake, hydraulic oil flows out from entering oil discharge passage, the power that piston upper surface is subject to starts to reduce, piston starts radial outward movement under spring force effect, finally return to the state that brake facing is separated with axle.
A kind of brake gear constructed by said method, as shown in drawings, comprise turning cylinder 6, the annular chamber 9 be provided with into oil discharge passage 3 is enclosed within turning cylinder 6 and the line of centers of annular chamber 9 overlaps with the line of centers of turning cylinder 6, the inner ring of annular chamber 9 is provided with path 10, gap 11 is formed between this annular chamber 9 and turning cylinder 6, in at least 2 brake facing 2(the present embodiment, brake facing is 3) to be evenly distributed in gap 11 and this brake facing 2 is consistent apart from the distance between center line of turning cylinder 6, in the non-operative end of brake facing 2, piston 1 is set, piston 1 inserts annular chamber path 10 and stretches in the cavity 12 of annular chamber 9, block 1 is provided with at the middle part of piston 1, block 27 is provided with in the bottom of path 10, spring 4 to be enclosed within piston 1 and to coordinate with block 1 and block 27, hydraulic oil is full of in the cavity 12 of annular chamber 9, this brake facing 2 driving surface is circular configuration, its radius size is consistent with the radius size of its corresponding turning cylinder 6, rubber ring 8 is provided with to prevent the leakage of hydraulic oil between path 10 and piston 1.
