Abstract
The utility model discloses a bogie integrated unit brake device which is a novel structure of a railroad wagon brake system and adopts a parallelogram structure. A brake cylinder is integrated on a brake beam frame. A wagon body and a bogie are connected only by a brake air pipe and a hand brake lever besides a center plate and a side bearing which are required by traction. No brake draw bar and matched auxiliary hoisting components, which are required by the traditional base brake device of the wagon, are arranged. Brake force is generated by the brake cylinder and is transmitted to the brake beam through a brake push rod below a swing bolster, and the brake beam drives a brake shoe to brake. The brake cylinder adopts a structure integrating the cylinder body with a brake slack adjuster, and is provided with a manpower hand brake device.
Description
Technical field
The utility model relates to a kind of bogie truck integrated type brake device.
Background technology
Technical development along with railway truck, original brake system foundation brake structure more and more embodies its limitation, the layout of brake equipment is comparatively complicated, adopted the multi-grade lever transmission mechanism in the brake system, brake lever quantity and lever connection lifting associate member are more, reduce braking and the reliability of alleviating, also reduced the transmission efficiency of brake system.Therefore, at the particularly development on special purpose freight car of China railways lorry, employing bogie truck integrated type brake device, be very necessary with transmission efficiency and the safe reliability that improves brake system.
Summary of the invention
Technical matters for the transmission efficiency that solves original structure limitation layout complexity, reliability and brake system, the utility model discloses a kind of bogie truck integrated type brake device, it is characterized in that, adopt parallelogram sturcutre, brake cylinder casing is integrated on the brake beam frame, whole device is directly installed on the bogie truck, and being connected except drawing required cartridge and side bearing between car body and the bogie truck only has braking air pipe and parking brake lever.This bogie truck integrated form unit brake device is a kind of new structure of rail wagon brake system, adopt parallelogram sturcutre, brake cylinder casing is integrated on the brake beam frame, whole device is directly installed on the bogie truck, being connected except drawing required cartridge and side bearing between car body and the bogie truck, have only braking air pipe and parking brake lever, there are not required lever connection of lorry tradition foundation brake rigging and the attached lifting part that matches with it, braking force produces by brake cylinder, brake push rod by bolster fish belly sill structure below is delivered to brake beam, and brake beam drives Block brake.Brake cylinder adopts cylinder body and the integrated structure of brake slack adjuster, and has manpower hand brake device (hand brake device).
Principle is as follows: piston and cylinder body relative motion, promote rotating lever, and make braking girder and auxiliary girder do rightabout motion, driving brake head and brake shoe does braking or alleviates action, when brake clearance was excessive, the brake slack adjuster automatic compensation kept brake clearance constant.This products characteristics: the high driving efficiency height of (1) driving efficiency is the most outstanding advantage of bogie truck integrated form unit brake device.Because of not having lever connection and supporting with it lifting associate member, driving efficiency can be up to 80%.Without any influence, therefore, the variation range of driving efficiency is also less to its driving efficiency in the variation of bogie truck amount of deflection.Full car brake shoe distribution of forces is also relatively more even, and the difference of eight blocks of minimum and maximum pressure of brake shoe is less than 10%.
(2) wheel rim abrasion less, the life-span is long, adorn the bogie truck of traditional lever foundation brake rigging, will produce a twist moment at glancing impact, when bogie truck is middle rod-pulling type, truck dead lever is connected on the bolster with pin, and this moment of torsion may cause the abrasion that the wheel rim of two diagonal positions contacts with rail head; When bogie truck is drop-down rod-type, when truck dead lever is connected on the car body with pin, operating bogie truck is offseted to one side, make two wheel rims of a side contact and wear away with rail head simultaneously.Bogie truck integrated form unit brake device thereby can not produce moment of torsion owing to have the brake shoe pressure of symmetry.When brake is done the time spent, bogie truck can not be out of shape, and can not cause abnormal abrasion between wheel rim and rail.
3. bogie truck integrated form unit brake device also has in light weightly, simple in structure, and parts are few, and advantage is installed and maintenance is convenient etc.Also because of it need not devices such as brake cylinder, brake lever, lever connection are installed on car body, for body construction design is brought great convenience.For example vehicles such as foodstuff hopper wagon, double-deck container flat car, bathtub formula open-top car are suitable for dress bogie truck integrated form unit brake device most.
Description of drawings
The utility model will illustrate that wherein: Fig. 1 is a bogie truck integrated form unit brake device constructional drawing by example and with reference to the mode of accompanying drawing.1-main brake beam, the secondary brake beam of 2-, 3-brake cylinder, 4-rotating lever, 5-brake push rod, 6-brake head.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
This bogie truck integrated form unit brake device is a kind of new structure of rail wagon brake system, adopt parallelogram sturcutre, brake cylinder casing is integrated on the brake beam frame, whole device is directly installed on the bogie truck, being connected except drawing required cartridge and side bearing between car body and the bogie truck, have only braking air pipe and parking brake lever, there are not required lever connection of lorry tradition foundation brake rigging and the attached lifting part that matches with it, braking force produces by brake cylinder, be delivered to brake beam from the brake push rod by the bolster below, brake beam drives Block brake.Brake cylinder adopts cylinder body and the integrated structure of brake slack adjuster, and has manpower hand brake device (hand brake device).
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. bogie truck integrated type brake device, it is characterized in that, adopt parallelogram sturcutre, brake cylinder casing is integrated on the brake beam frame, whole device is directly installed on the bogie truck, being connected except drawing required cartridge and side bearing between car body and the bogie truck, braking air pipe and parking brake lever are only arranged.
2. bogie truck integrated type brake device according to claim 1 is characterized in that, described brake cylinder adopts cylinder body and the integrated structure of brake slack adjuster, and has the manpower hand brake device.
