Technical field
The utility model relates to a kind of brake gear, and the hydraulic pressure that relates in particular to traveling gear, high-speed rail vehicle, towing cloth laying mechanism, high speed traveling is embraced the rail brake gear, belongs to railroad vehicle braking technology field.
Background technology
At present, the brake mode that the rail locomotive vehicle adopts is Block brake the most generally, cylinder iron or watt shape slipper made of other materials, holds wheel tread tightly at glancing impact, by friction wheel is stopped operating; And more later-model brake mode employing is disc braking, it is that brake disc is installed on axletree or in the wheel web side, make two brake linings making with synthetic material press the brake disc side with the braking clamp, produce braking force, train is halted by friction.These two kinds of brake mode all are to utilize the friction force of wheel and track to realize braking, make the wearing and tearing of wheel and track easily, and the maximum deceleration of this brake mode also has only μ g.If traveling gear requires to realize that maximum speed is acceleration, speed stabilizing and the moderating process of 5m/s in short travel, and requires traveling gear to operate steadily, so utilize above-mentioned technology to realize.
Summary of the invention
The utility model provides a kind of hydraulic pressure to embrace the rail brake gear, utilizes the fluid control brake facing to hold track tightly, impels track travel mechanism gradual braking in the short travel under the friction force effect of brake plate and track side surfaces.
Hydraulic pressure is embraced the rail brake gear, comprise energy storage, clamping cylinder, piston rod, hinged A, vertical connecting rod, spring, the connecting rod pedestal, the brake pedestal, brake facing, hinged B, vertical track adjusting wheel, horizontal guide sheave, waling stripe, hinged C, the pedestal that wherein brakes is symmetrical set in the both sides of wheel and is fixed on the bottom, compartment, brake pedestal upper fixed connecting rod pedestal, on the waling stripe of brake base interior a vertical track adjusting wheel and two horizontal guide sheaves are set, the front end of waling stripe is installed brake facing, vertically the lower end and the waling stripe of connecting rod are hinged by hinged C, vertically the middle hypomere of connecting rod and connecting rod pedestal are hinged by hinged B, vertically the upper end of connecting rod and piston rod are hinged by hinged A, piston rod is connected with clamping cylinder, and clamping cylinder is connected with energy storage; A cover brake gear is respectively installed at four wheel position places of car body.
Waling stripe in the brake base interior utilizes one vertically to lead track adjusting wheel and two horizontal guide sheaves lead, and the power of can reducing friction prevents that simultaneously catching phenomenon from appearring in waling stripe;
Principle of work: need glancing impact at vehicle, energy storage is to the clamping cylinder fuel feeding, the clamping cylinder piston rod is outwards done straight-line motion, piston rod promotes vertical connecting rod and rotates counterclockwise around hinged B, and then promote waling stripe and press close to the side of rail along the brake base interior, rely on the friction force between brake facing and the rail side to make car brakeing; When hydraulic pressure was embraced rail brake gear releasing orientation, this moment, the oil-feed loop was communicated with the clamping cylinder oil back chamber, made piston rod to retraction under pressure oil and spring force effect, unclamped track thereby drive brake facing, finished the releasing of braking.
In order to realize that a plurality of clamping cylinders can be synchronous in brake process, synchronized cylinder is set before clamping cylinder; Between clamping cylinder and synchronized cylinder, increase a hydraulically-controlled one-way valve simultaneously, prevent that the appearance of the oil in clamping cylinder backflow makes braking failure in the braking procedure, simultaneously again can be when device be in releasing orientation, the modulated pressure check valve is in reverse opening, and brake gear can be unclamped smoothly.
Beneficial effect: the utility model utilizes synchronized cylinder to guarantee several groups of synchronisms of embracing rail device clamping cylinder, thereby can guarantee steady, the safety of the braking procedure of traveling gear; Magnification factor by adjusting energy storage, diameter of piston, connecting rod mechanism etc. is adjusted the positive pressure of brake facing and track on request simultaneously, thereby the braking distance of realizing traveling gear is stepless within the specific limits adjustable.
