Description
One, technical field
The utility model belongs to the rolling stock retarder, particularly relates to the electric car retarder that adopts six bar mechanism.
Two, background technology
Domestic existing electric car retarder or title elec. vehicle retarder (hereinafter to be referred as electric speed reducer), its used electronic device is made up of wire wound internal stator, tubular outer rotor etc., minimum starting current 18A, electronic device and transfer bar mechanism adopt single-stage crank four-bar linkage, and the locking angle of crank and connecting rod (also being electronic device rotor and connecting rod) was 2～5 ° at dead point.Its existing problems are: 1) the complete machine electric current is big, and the distribution circuit electric current is big; 2) transmission device is crossed the dead point locking, if impact for a long time, wear and tear, the locking angle is strengthened, and has the hidden danger of not alleviating (folder stops); 3) the too little then locking in locking angle shakiness too greatly then is difficult for release, causes debugging and maintenance difficult; 4) motor reel directly bears the impact forces of car load, influences the service life of electrical motor.
Three, summary of the invention:
The purpose of this utility model provides a kind of electric car retarder, and it can reduce the impact of glancing impact vehicle to motor shaft, improves electrical machinery life, locking is reliable, flexible movements, the reliability of assurance electric speed reducer performance satisfies the grouping operation requirement of railway classification yard to various vehicles.
The purpose of this utility model is achieved in that electric car retarder, comprise electrical motor, push rod, brake clamp group, braking rail and concrete slab sleeper, it also comprises six bar mechanism, and described six bar mechanism is composed in series by slide block rocker mechanism and piston crank mechanism.
The utility model compared with prior art has following advantage:
1) the six bar mechanism two-stage is transmitted, and reinforcement strengthens, right angle straight line dual tandem locking, and locking is reliable, and release of brake is reliable, eliminated the hidden danger of not alleviating (folder stops).2) adopt internal rotor, external stator motor and control system, under the 380V rated voltage, working current remains on below 10 amperes.3) the repetition glancing impact has lasting promotion and time slow characteristic with cylinder.4) insensitive to error, allow bigger manufacturing, installation error, allow bigger abrasion loss, long service life.5) maintenance, maintenance are simply, and be safe and reliable to operation.6) can directly transform vehicle retarders such as existing pneumatics, improvement expenses is low.

Fig. 1 looks cutaway view for the utility model electric car retarder electrical motor master;
Fig. 2 is the utility model motor stator winding configuration figure;
Fig. 3 is the alternate constructional drawing of the big sulculus of the utility model motor rotor;
Fig. 4 is the utility model electric car retarder structural representation;
Fig. 5 is the utility model six bar mechanism scheme drawing.
Five, the specific embodiment:
The utility model is made up of brake clamp group 7, braking rail 8, concrete slab sleeper 10, push rod 6 and six bar mechanism 17 and the electrical motor 15 of gravity vehicle reducer.Crank throw 11, connecting rod 12, rocking handle 14, crank 13, installation base plate 16 constitute the six bar mechanism 17 that two-stages are transmitted dual locking, (seeing accompanying drawing 5).
Electrical motor 15 is formed (see figure 1) by support 1, rotor 2, stator 3, end cap 4, position outgoing mechanism 5, stator winding adopts the informal winding that does not wait circle, unequal span square, stator slot is multiple-grooved deep groove structure (winding configuration such as Fig. 2), rotor slot shape adopts the alternate structure of big sulculus (as Fig. 3), in order to make electrical motor can adapt to impact load, motor casing adopts steel plate structure.
The utility model electric car retarder is to be power, to put in place with crank throw 11 output torques and by push rod 6 promotion brake clamp groups 7 with motor 15, vehicle weight is by the transmission of stock rail 9 and brake clamp group 7, make 8 pairs of wheels of braking rail produce lateral pressure, reach the braking purpose.
Transmission device as shown in Figure 1 is a six bar mechanism, adopt the series connection of slide block rocker mechanism and piston crank mechanism, crank 13 rotates around motor shaft, driving rocking handle 14 rotates; rocking handle 14 passes through connecting rod 12 and drives crank throws 11 rotations; crank throw 11 promotes brake clamp group 7 synchronous liftings by push rod group 6 or falls, and finishes braking and alleviation.When braking position, crank 13 is vertical with the guide groove of rocking handle 14, its locking vertical locking angle is ± 10 °, and the center of turn of rocking handle 14; 3 of the point of connection of the point of connection of rocking handle 14 and connecting rod 12 and connecting rod 12 and crank throw 11 are in line; its straight line locking angle be ± 5 °, formation right angle straight line two-stage series connection locking, and locking is reliable; But also can reach the locking purpose in ° scope of dead point-5.13 need of crank can be alleviated with very little power during alleviation, and release of brake is reliable, limits piston crank mechanism simultaneously and crosses the dead point, has eliminated the hidden danger of not alleviating (folder stops).
Electrical motor 15 adopts internal rotors, external stator alternating-current motor/AC motor, can the long period stall, and stator winding adopts the informal winding that does not wait circle, unequal span square, and the rotational angle of electrical motor 15 is spent greater than 180.This winding has effectively weakened the influence to fundamental wave magnetic field of slot ripples and high order harmonic, thereby has increased the electrical motor locked-rotor torque, has improved the motor power (output) factor.Rotor slot shape adopts the alternate structure of big sulculus, and this structure is regulating tank leakage field size effectively, thereby improves the motor starting torque, reduces the motor starting electric current.Stator slot adopts the multiple-grooved deep groove structure, has increased the payload space of lead, and it is close to have reduced the stator electricity, has improved motor efficiency.Whole drive part is repeating lasting promotion and time slow characteristic that glancing impact has cylinder, and the motor power back-off of carrying out in parallel with electric capacitor improves power factor, has reduced the distribution circuit electric current.
