Description
Technical field
The invention belongs to guideway vehicle service brake field, thereby specifically by the pole shoe of increase magnetic rail brake device and the step-up system of the increase of the friction force between rail braking force
.
Background technology
Magnetic rail brake device mainly consists of brake beam, suspension and jacking system, magnet, pole shoe etc., as number of patent application is 201210408048.7, name is called " a kind of electromagnetic magnetic rail brake " described drg.The principle of work of electromagnetic rail brake is: the pole shoe of drg under magnetic action, and between rail because relative motion produces friction drag, realize brake snub.
The cross section of rail is I shape, in the middle of its end face, it is plane, but the fillet surface that Shi Yu side, the end face left and right sides connects, the bottom of pole shoe is flat-bottom structure, during the pole shoe braking, only with the plane in the middle of rail surface, contact, and do not contact with the curved surface of the rail surface left and right sides, this just causes the area of contact of pole shoe and rail limited, and then causes deceleration and stopping performance not to be not fully exerted.
Summary of the invention
The objective of the invention is for existing magnetic rail brake device limited because of the area of contact of pole shoe and rail in when braking, the defect that deceleration and stopping performance is not fully exerted and a kind of simple in structure, dependable performance is provided, can improves the vertical gliding style magnetic rail brake device step-up system of braking force.
The technical solution used in the present invention is: comprise the pole shoe be positioned at directly over rail surface, the pole shoe bottom is the boss structure that transverse width is less than the rail transverse width, both lateral sides at boss structure respectively arranges a side plate and a T-shaped brake silpper, homonymy at boss structure, be fixedly connected with between the side plate of boss structure and boss structure and surround a rectangular channel, the top that holds several holddown springs and T-shaped brake silpper in this rectangular channel, stretch out outside rectangular channel downwards the bottom of T-shaped brake silpper, and T-shaped brake silpper can slide up and down in rectangular channel; The holddown spring top is pressed against on boss structure, and the holddown spring bottom is supported on T-shaped brake silpper end face; Be provided with the arc-shaped guide rail groove in the bottom of T-shaped brake silpper, the fillet surface of this arc-shaped guide rail groove and rail surface both sides matches, when the boss structure bottom surface of pole shoe contacts with the end face of rail is middle, the fillet surface of described arc-shaped guide rail groove and described rail surface both sides fits tightly.
The present invention normally travels, does not change magnetic rail brake device agent structure and operating voltage in the situation that do not affect train, can increase the area of contact of pole shoe and rail, thereby effectively increase magnetic rail brake device and interorbital magnetic attraction, thereby increase braking force, improve the magnetic rail brake device deceleration and stopping performance.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
Fig. 1 is structure cutaway view of the present invention and scheme of installation thereof;
Fig. 2 is the upward view removed in Fig. 1 after rail 5;
In figure: the 1-pole shoe; The 2-holddown spring; 3-T type brake silpper; The 4-side plate; The 5-rail; The 6-baffle plate; The 7-boss structure; 8-arc-shaped guide rail groove.
The specific embodiment
As shown in Figure 1, the pole shoe 1 of magnetic rail brake device be positioned at rail 5 end faces directly over, pole shoe 1 bottom is boss structure 7, the bottom surface of boss structure 7 is middle with the end face of rail 5 is two corresponding contact leveies, the end face both sides of rail 5 are curved surfaces of transition, and the transverse width of boss structure 7 is less than the transverse width of rail 6.
Both lateral sides at boss structure 7 respectively arranges a side plate 4 and a T-shaped brake silpper 3, side plate 4 is fixed by screws on boss structure 7, homonymy at boss structure 7, surround a rectangular channel between side plate 4 and boss structure 7, the top that holds several holddown springs 2 and T-shaped brake silpper 3 in this rectangular channel, the top of holddown spring 2 is pressed against on boss structure 7, and the bottom of holddown spring 2 is supported on the end face of T-shaped brake silpper 3.Under the effect of holddown spring 2 and rail 5, T-shaped brake silpper 3 can slide up and down in rectangular channel, in slip place, can on T-shaped brake silpper 3, boss structure 7 or side plate 4, be provided with the guide-track groove that is beneficial to slip.
The bottom of T-shaped brake silpper 3 is stretched out outside rectangular channel downwards, and be provided with arc-shaped guide rail groove 8 in the bottom of T-shaped brake silpper 3, this arc-shaped guide rail groove 8 matches with the fillet surface of rail 5 end face both sides, the radius of curvature of arc-shaped guide rail groove 8 is identical with the radius of curvature of the fillet surface of rail 5 end face both sides, like this, during braking, when boss structure 7 bottom surfaces of pole shoe 1 contact with the end face of rail 5 is middle, under the effect of holddown spring 2, the arc-shaped guide rail groove 8 of brake silpper 3 bottoms is with together with the fillet surface of the end face both sides of rail 5 fits tightly, make binding face also become the drag friction contact surface, increased the area of contact of pole shoe 1 with rail 5, increased braking force.
As shown in Figure 2, on rail 5 is vertical, in vertical both end sides of brake silpper 3, a baffle plate 6, two baffle plates 6 is set respectively and is bolted on pole shoe 1, to limit the motion in the vertical of two brake silppers 3.
While starting to brake, under the effect of holddown spring 2, brake silpper 3 is in upper/lower positions, when brake silpper 3 is subject to rail 5 end face application force, and holddown spring 2 upward movements; Two baffle plates 6 of brake silpper 3 vertical both end sides have limited seesawing of brake silpper 3; Boss structure 7 parts of pole shoe 1 are main brake portions, and two brake silppers 3 are auxiliary braking parts; Baffle plate 6 transmits the braking force of brake silpper 3 to magnetic rail brake device.
When magnetic rail brake device is braked on straight track, the boss structure 7 of pole shoe 1 and two brake silppers 3 and the whole end face laminating of rail 5, thus increased the area of contact of magnetic rail brake device pole shoe 1 with rail 5, improve the braking force of drg.
When magnetic rail brake device is braked on uneven track or turnout, the arc-shaped guide rail groove 8 of two brake silppers 3 is not harmonious with the fillet surface of rail 5 end face both sides, under the effect of adhesive magnetic force, brake silpper 3 is upwards promoted by rail 5 tops, with the boss structure 7 that guarantees pole shoe 1, with in the middle of rail 5 end faces, contact, now, can obtain small air gap between the fillet surface of arc-shaped guide rail groove 8 and rail 5 end face both sides.
When magnetic rail brake device finishes braking, jacking system rising magnetic rail brake device, brake silpper 3 separates with rail 5, no longer is subject to the application force of rail 5, only under the effect of holddown spring 2, in the magnetic rail brake device foot.
