Technical field
The utility model relates to railway freight-car braking technology field, particularly a kind of two-way self-regulated stroke reinforcement master cylinder.
Background technique
Domestic lorry generally adopts traditional lever-type brake all the time; And, lorry guarantees for providing reliable braking ability; But along with domestic lorry technology is fast-developing; Axle is heavy, speed improves constantly, and requires increasingly high to reliability, retardation efficiency, integrated degree and the repair and maintenance performance etc. of railway freight-car braking device.
Summary of the invention
One of purpose of the utility model provides a kind of effective raising vehicle braked efficient and improves the bad two-way self-regulated stroke reinforcement master cylinder of release of brake.
According to an aspect of the utility model, provide a kind of two-way self-regulated stroke reinforcement master cylinder to comprise: to have the master cylinder of piston rod, the step-up system and the two-way self-regulated stroke apparatus of amplification braking force;
Said master cylinder is connected with said step-up system, and said step-up system is connected with said two-way self-regulated stroke apparatus.
Further, said step-up system comprises: piston, be filled with the cavity of flowing medium;
Said master cylinder is connected with flowing medium in the said cavity through its piston rod, and said piston is connected with flowing medium in the said cavity.
Further, said piston area is greater than said piston rod area;
Further, be provided with limiting block and controlling rod between said two-way self-regulated stroke apparatus and the said step-up system, exist in the gap between said limiting block and the controlling rod, said limiting block is arranged on the cylinder cap.
Further, said preceding brake beam is isosceles triangular structure with the back brake beam; Pillar before said on brake beam and the back brake beam is arranged on this isoceles triangle shape perpendicular bisector position.
Further, said two-way self-regulated stroke reinforcement master cylinder front end is connected the middle part of said front brake lever, and the rear end is connected the middle part of back brake lever.

Description of drawings
Fig. 1 is two-way self-regulated stroke reinforcement master cylinder structural representation;
Fig. 2 is the partial structurtes schematic representation of two-way self-regulated stroke reinforcement master cylinder among Fig. 1;
The utility model purpose, function and advantage will combine embodiment, further specify with reference to accompanying drawing.
Embodiment
As shown in Figure 1, the two-way self-regulated stroke reinforcement master cylinder that the utility model embodiment provides comprises master cylinder 13, step-up system 12 and two-way self-regulated stroke apparatus 11.If step-up system 12 is not set, when being delivered to brake shoe, the braking force that master cylinder 13 produces will be dwindled, and the demand of braking force in the time of can not satisfying vehicle parking is the amplification that realizes braking force, and the utility model is integrated 1 step-up system 12 on master cylinder 13.As shown in Figure 4, step-up system 12 comprises piston 16, is filled with the cavity of flowing medium 17.Piston 16 areas of braking force output terminal are greater than piston rod 18 areas of braking force input end, and the principle of utilizing the fluid pressure to transmit is amplified braking force, and the adjustment of braking force Amplification factor can realize with the area ratio of piston rod 18 through changing piston 16.In addition, also can realize the amplification of braking force through mechanical booster mechanism.
When brake shoe or wheel wear, generally can cause the gap between brake shoe and the wheel to increase; When brake shoe or wheel renew, generally can cause the gap between brake shoe and the wheel to be reduced.This moment is long or shortening through the automatic accent of two-way self-regulated stroke apparatus 11, can keep the piston stroke of master cylinder 13 to be stabilized in the tolerance range of regulation.As shown in Figure 2, the boss of controlling rod 15 leaves gap A with the limiting block 14 that is installed on the cylinder cap 19, and the dosage of regulating the cavity inner fluid medium 17 of step-up system 12 can determine the size of gap A, thus the piston stroke length of control brake cylinder 13.
When vehicle was implemented the wind braking, the piston rod 18 that master cylinder 13 protracts was passed to piston 16 through extrusion fluid medium 17 with the braking force pressure, under the situation that pressure equates; Piston 16 areas are greater than piston rod 18 areas; Thereby amplification braking force, this moment, piston 16 moved forward under the propelling movement of flowing medium 17, drove two-way self-regulated stroke apparatus 11 and moved; Move thereby drive controlling rod 15, make itself and the limiting block 14 that is installed on the cylinder cap 19 produce relative displacement.After gap A elimination, when piston 16 continuation were mobile, 14 of limiting blocks can stop that controlling rod 15 continues to move, and move thereby trigger two-way self-regulated stroke apparatus 11, and two-way self-regulated stroke apparatus 11 meeting foundations are taken turns the size accent length or the shortening automatically in watt gaps.Wherein, two-way self-regulated stroke apparatus 11 has been done detailed presentations in the patent of CN200920227667.X, repeats no more.
The two-way self-regulated stroke reinforcement master cylinder that provides according to the utility model can effectively improve vehicle braked efficient and improve release of brake bad.
The foregoing description is the utility model preferred implementation; But the mode of execution of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
