According to the track train and high-speed track train emergency safe braking auxiliary device, a brake auxiliary device body is arranged between two adjacent hub bridge frames on the same side of each turning frame of the existing track train and an existing high-speed track train, and the brake auxiliary device body can be freely retracted vertically and can increase friction moment when contacting the steel rail. The device is composed of a friction piece, a friction piece seat, a guide moving column, a base, a returning spring, a linkage rod, a brake air chamber pushing rod and a brake air chamber. The device can increase the adhesive force and friction force between the turning frame and the steel rail of the train during a brake process, the track train and the high-speed track train driving in high speed can rapidly shorten break distance and stop safely on the emergency condition.

Description

Track train and high-speed track train emergency safety brake auxiliary device
Technical field
The utility model relates to a kind of track train and high-speed track train emergency safety brake auxiliary device, the track train of running at high speed and high-speed track train is in case of emergency slowed down rapidly shorten the brake auxiliary device of stopping distance and emergency.
Background technology
At present, known existing track train and high-speed track train wheel drg are drum-type and disc type.In the process of braking and deceleration, utilize the friction force of friction lining and wheel hub or friction lining and brake disc to reach the effect of slowing down and stopping.But the length of stopping distance and the speed of travelling, braking force, adhesion value are relevant.Wheel hub and rail because of the track train all is metal again, and be again that a contact adhesive ability is less between them, adhesive ability can be less when train was run at high speed, so easily make wheel hub and rail produce slippage in the process of braking, in case of emergency can not effectively slow down and shorten stopping distance crashes easily.
The utility model content
The utility model is to produce the problem that stopping distance can not be effectively slowed down and shorten in slippage in order to overcome existing track train and high-speed track train wheel hub and rail adhesive ability in braking procedure than Xiao Yi.The utility model purpose is to solve adhesive ability and friction force between the bogie truck that can increase train in the process that track train in running at high speed or high-speed track train take emergency braking and the rail, the train of running at high speed is in case of emergency slowed down rapidly shorten the brake auxiliary device of stopping distance and emergency.
The utility model institute's employing scheme of dealing with problems is: can be freely when in the middle of adjacent two the wheel hub crane span structures of bogie truck homonymy of existing track train and high-speed track train, a braking being installed up and down flexible and can contact with rail can the increasing friction force square brake auxiliary device.This brake auxiliary device adopts vapour-pressure type to promote principle and vertically is placed between adjacent two wheel hubs of bogie truck homonymy of track train and high-speed track train, and two wheel hubs of longitudinal projection and homonymy and rail coincide, and packs up when not working not and the rail joint.This brake auxiliary device by friction lining, the friction bar, guiding movement post, pedestal, pull back spring, gangbar, compressed air brake cylinder pushes away post and compressed air brake cylinder forms.This brake auxiliary device at ordinary times need not, in case of emergency control brake control valve by the engine driver, pressurized air enters compressed air brake cylinder and acts on compressed air brake cylinder and push away on the post, compressed air brake cylinder pushes away post promotion gangbar and moves the tension force that overcomes pull back spring, make the guiding movement post move down promotion friction bar and make friction lining and rail joint, produce the friction moment auxiliary braking.
The beneficial effects of the utility model are, this brake auxiliary device is to contact to cause that adhesive ability is little and cause the long problem of stopping distance during in braking with rail efficiently solving wheel hub because of existing track train and high-speed track train under the prerequisite that does not change original brake system, and the track train that utilizes the method for friction moment between the bogie truck that increases track train and high-speed track train and the rail to make to run at high speed and high-speed track train in case of emergency can slow down rapidly and shorten stopping distance and emergency.
Description of drawings
Fig. 1 is the constructional drawing of the utility model embodiment.
Fig. 2 is the longitudinal profile constructional drawing of the utility model embodiment.1 friction lining among the figure, 2 friction bars, 3 guiding movement posts, 4 pedestals, 5 pull back springs, 6 compressed air brake cylinders push away post, 7 gangbar, 8 compressed air brake cylinders, 9 rail, 10 turn to support body.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
In the embodiment shown in fig. 1, the friction lining of brake auxiliary device (1) is mounted and fixed on the friction bar (2), and the two is become one; Friction bar (2) links to each other with guiding movement post (3); Guiding movement post (3) links to each other with gangbar (7); Gangbar (7) pushes away post (6) with compressed air brake cylinder and contacts; It is that an interlock body makes between them related each other with compressed air brake cylinder (8) that compressed air brake cylinder pushes away post (6).Compressed air brake cylinder when taking emergency braking (8) is under compressed-air actuated application force, being applied to compressed air brake cylinder pushes away on the post (6), so compressed air brake cylinder pushes away post (6) and moves down and promote gangbar (7) and also move down, the tension force promotion guiding movement post (3) that gangbar (7) just overcomes pull back spring (5) moves down, because friction bar (2) links to each other with guiding movement post (3), friction bar (2) just moves down, friction lining (1) on the friction bar (2) just rubs with rail (9) mutually by descending movement, because having larger area and rail, friction lining rubs mutually, can produce very large friction moment, thereby play the effect of auxiliary braking.
In embodiment illustrated in fig. 2, when engine driver's emergency braking, braking pressure enters brake chamber (8), compressed air brake cylinder pushes away stressed the moving down of post (6), act on the gangbar (7), the tension force that gangbar (7) just overcomes pull back spring (5) promotes guiding movement post (3) and moves down, and the bar that rubs simultaneously (2) moves down band movable friction plate (1) and moves down with rail (9) and rub mutually, plays the effect of the auxiliary braking that rubs.In order to improve the safety in braking procedure, friction bar (2) and friction lining (1) are provided with guide rib near the rail inboard, can increase friction force on the one hand, can play directional tagging on the other hand, prevent among braking procedure, occur partially stopping and cause the generation of derail accident, can improve the safety of braking.It is the brake auxiliary device that is installed in bogie truck one side of track train and high-speed track train shown in the figure, each bogie truck is installed two covers in the practical application, it is left and right each cover, the raising safety of can anti-biasly stopping so on the one hand can increase the friction moment between train bogie truck and the rail on the other hand greatly.
