Abstract
The utility model discloses an electromagnetic rail brake for light rail electric car, intended to provide an electromagnetic brake with braking force unrelated to adhesive force, which has compact structure and small volume and meets the requirements of strong braking force and short braking distance. The utility model consists of a leading-out wire socket (1), a coil (2), an iron core (3), a magnetic pole (4), a slider (5) and a clapboard (9). When the rail is uneven, the magnetic pole and the slider at both ends of the iron core are made into flexible joint brake shoe structure, so as to ensure better contact and joint of the slider and the steel rail surface. The coil (2) wraps the iron core (3) closely and the integer can be replaced by the slider (12). A bolt (5), a screw (6) and a pin (8) are adopted to fix and integrate the magnetic clapboard (9), the coil (2), the iron core (3), the magnetic pole (4), a magnetic pole (11), a slider (7) and a slider (12) respectively.
Description
Light rail electrical car is that a kind of back that switches on produces suction, electric energy is transformed into the magnetic cell electrical equipment of mechanical energy ferromagnetic material with the electromagnetic path drg, is specially adapted to light rail electrical car and uses as brake equipment.
The electromagnetic path drg is special match appliance for " six two hinged light rail electrical cars " brake system development, light rail electrical car is as the urban passenger vehicle, because the station square is short, speed is fast, and braking in service is frequent, require brake system sensitivity, reliable, stopping distance is short, and the drg by existing compressed air brake or the effect of utilization adhesion principle all fails to satisfy requirements, in the time of particularly outside braking force is increased to the binding force limit, the danger of sliding will appear forcing in light rail electrical car.
The purpose of this utility model is to provide a kind of its braking force and the irrelevant electromagnetic path drg of binding force, and compact conformation, volume be little, it is big to satisfy braking force, the requirement that stopping distance is short.
The utility model is to realize like this, referring to Fig. 1, Fig. 2, structure shown in Figure 3, this electromagnetic path drg is based on magnetizing coil, the huge magnetic flux that energising is magnetized and produces, attempt forms C/LOOP by rail (10), produce to inhale the magnetic-drag (the invar rail is a transfixion) to rail, this magnetic-drag is exactly our noted earlier and irrelevant braking force of binding force.The utility model is made up of pig-tail wire socket (1), coil (2), (3), magnetic pole (4) unshakable in one's determination, slide block (7), magnetic isolation plate (9) etc., under the situation of track injustice, fit for guaranteeing that slide block contacts with the rail face better, the magnetic pole at iron core two ends and slide block are all made movable joint brake shoe structure, magnetic pole can be divided into plurality of small blocks magnetic pole (4), some bulk magnetic poles (11), symmetry blocks is placed in the both sides of iron core (3).Slide block is divided into some small slide blocks (7) and some big slide blocks (12), symmetry blocks is placed on the below of iron core (3) two ends pole plate, with bolt (5), spiral shell (6), pin (8), with magnetic isolation plate (9), coil (2), iron core (3), magnetic pole (4), magnetic pole (11), slide block (7), slide block (12) are fixed in aggregates respectively.In braking procedure, slide block attracts mutually with rail all the time, but because inertia light rail car is still travelling forward, thereby between small slide block (7), big slide block (12) and the rail (10) big friction is arranged, for guaranteeing that rail is not worn, the manufacturing of mild steel material is adopted in its slide block (7), (12), so slide block allows wearing and tearing, and allows regularly to be replaced.The contact portion (being the first half of rail section) of slide block (12) and slide block (7) and rail (10) becomes the part of the whole magnetic circuit of electromagnetic path drg.The magnetic flux Ф that coil produces is by following order: iron core → magnetic pole → slide block → rail → slide block → magnetic pole, form a complete closed magnetic circuit.Coil (2) hard-pressed bale iron core (3) is designed to the complete closed structure, has the invasion and attack and the anti-vibration functions of opposing rain, snow, reliable operation, and the life-span is long.

Fig. 2 light rail electrical car electromagnetic path drg birds-eye view
Fig. 3 light rail electrical car electromagnetic path drg A-A cutaway view
The enforcement figure front view that Fig. 4 electromagnetic path drg is installed under the light rail electrical car vehicle frame
The enforcement figure birds-eye view that Fig. 5 electromagnetic path drg is installed under the light rail electrical car vehicle frame
Below in conjunction with accompanying drawing the utility model is further described (seeing Fig. 4, Fig. 5).
Electromagnetic path drg (2) is installed in the rail top between the two axles symmetrically, and the distance of the face that leaves the right or normal track is 50mm; Two single electromagnetic path drgs are guaranteed glancing impact by transmission bracket (3) and connecting rod (4) and support 5 compositions one integral body, and two electromagnetic path drgs actions synchronously.During work, cylinder (1) is under the pressurized air effect, overcome the spring counter-force, the promotion piston is downward, drives the electromagnetic path drg and moves down 50mm, and its slide block contacts with rail level, meanwhile, the magnetizing coil energising is produced a powerful magnetic flux by magnetic magnetic, and the minim gap between slide block and rail contact surface produces attractive force, and this magnetic attraction can also make light rail electrical car snap catch in very short distance; End of braking, the magnetizing coil outage, magnetic attraction is eliminated, and meanwhile, the pressurized air in the cylinder is also discharged fully, and the electromagnetic path drg under the reaction spring effect, returns to original initial position again in cylinder, for braking is next time prepared.The effect of transmission bracket (5) is glancing impact, can be brake-force transmission to vehicle frame.Thereby between small slide block (7), big slide block (12) and the rail (10) big friction is arranged, for guaranteeing that rail is not worn, the manufacturing of mild steel material is adopted in its slide block (7), (12), so slide block allows wearing and tearing, and allows regularly to be replaced.
