Abstract
A screw hand brake for railway freight car mainly comprises a flange, a support, a hand wheel, a hand brake screw, a stop screw and so on. The flange and the support are symmetrically and respectively fixed on the surface support and the bottom support of the car frame; the hand brake screw is horizontally mounted with the two ends inserted in the bearing holes of the flange and the support. The hand wheel is positioned on the further side of the surface and the hand wheel is connected with the end of the hand brake screw through the bearing hole of the flange. The stop screw is installed on the hand brake screw and a stop board in the slot of the bottom surface is mounted on the top of the hand brake screw to ensure the stop screw can only move in the direction of the axis in the screw thread section of the stop screw. Two trunnions linked with the brake system are installed on the two sides of the stop screw to control the action of the brake system. The device is of simple structure, low cost, reliable capability, convenient maintenance and high performance-price ratio, which is applicable to railway freight cars of low speed, small load and few train groups.
Description
Technical field
The utility model relates to the device that is suitable for the rail freight hand brake, refers to a kind of rail freight screw hand brake particularly.
Background technology
Rail freight divides by version with hand brake roughly Worm-gear type, axle chain type, folding shaft chain type, gear chained scheduling several.At present, what China's rail freight adopted mainly is the chain type hand brake, and NSW type and the FSW type hand brake of newly making the lorry employing promptly belong to the gear chain structure.These hand brakes have advantages such as braking force is big, easy to operate, braking is reliable, but also there are simultaneously defectives such as structure relative complex, parts are more, maintenance inconvenience, nearly 37 and 41, weight are respectively 35.9 kilograms and 38.5 kilograms respectively as the amount of parts of NSW type and FSW type hand brake, and parts mostly are machined piece and die mould spare greatly, and productive costs is higher.In Africa, Latin America and country in Southeast Asia, owing to be subjected to the constraint of technical merit, line condition, the technical merit of its rail freight is relatively low,, load-carrying lower as running velocity is light, train marshalling list is few etc., the hand brake that requires vehicle in this case is in dependable performance, its structure should be simple as far as possible, and operation and maintenance should be convenient as far as possible, and existing vehicle hand brake can not mate with it well at aspects such as cost performances.
Summary of the invention
The purpose of this utility model will provide a kind of simple in structure, with low cost, dependable performance and working service rail freight screw hand brake very easily exactly.
For realizing this purpose, the rail freight screw hand brake that the utility model is designed, mainly form by parts such as flange, bearing, handwheel, hand braking screw rod and spline nuts, described flange and bearing are the positioned opposite state, are separately fixed on the end face support and bottom bracket on the car body underframe, as the front and rear fulcrum of hand braking screw rod.Described hand braking screw rod is the horizontal arrangement state, its two ends are installed in respectively in the bearing hole of flange and bearing, can rotate in bearing hole.Described handwheel be arranged in described end face support the outside, it captives joint with an end of the hand braking screw rod that passes the flange bearing hole.Described spline nut is assembled on the hand braking screw flight section, the top design of spline nut has the spline retaining that is embedded in the described bottom bracket chute, the spline retaining can only slide in the chute of bottom bracket, and can not rotate, can only be to guarantee the spline nut at hand braking screw flight Duan Shangzuo axial-movement; The both sides of spline nut are provided with the gudgeon that links to each other with motor vehicle braking system, with the action of control vehicle brake system.
Further, stud with the wear resistant nylon lining in the bearing hole of above-mentioned flange and bearing respectively,, improve its work life to alleviate the wearing and tearing between the movable parts.Above-mentioned hand braking screw rod is provided with positioning retainer ring near the threaded one end section of bearing, is used for the location of spline nut, when the spline nut towards the motion of positioning retainer ring direction and when contacting with it, the spline nut i.e. no longer motion.Above-mentioned hand braking screw rod can design near the end of bearing one end and be sphere shape, is provided with the sphere wheel that matches with it simultaneously in the bearing hole of bearing, rotates flexibly to guarantee hand braking screw rod.
Advantage of the present utility model is: one, the hand braking screw rod that is adopted have the intrinsic auto-lock function of general T type thread screw, and it is simple in structure, running is stable, dependable performance.They are two years old, the whole parts that adopted are added up and are only had 12, less than 1/3rd of existing NSW type and FSW type hand brake amount of parts, about 20 kilograms of total weight, be about half that has NSW type and FSW type hand brake weight now, few, in light weight, the required manufacturing cost of its part can significantly reduce.Its three, the screw hand brake that is assembled into is simple to operate, use, easy to maintenance, cost performance is high, the railway truck configuration of be very suitable for that running velocity is lower, load-carrying is light, train marshalling list is few.
