Abstract

The invention discloses a bogie shaft-mounted disc type braking device which is characterized in that a braking unit is suspended on a braking lifting socket of a truss end sill, a braking disc is arranged on an axle in a wheel set axle box assembly, and gap is reserved between the braking disc and braking unit linings at two sides of the braking disc. Through the braking of the braking disc by the braking unit, the influences of the bogie braking device on the temperature and strength of the wheels and the abrasion effect of the bogie braking device on the wheel tread and the flange of the wheels in the braking course are reduced, and the service life of the wheels is prolonged; and in addition, the braking unit provided by the invention is suspended in the inner part of a bogie end sill, and has no requirement on limit.

Description

The shaft-mounted disc brake device of bogie truck
Technical field:
The invention belongs to subway car bogie technique, relate to the shaft-mounted disc brake device of bogie truck.
Background technology:
Traditional subway car truck brake rigging pattern mainly adopts the tread brake pattern, and the mode that friction takes place by brake pad and wheel is implemented braking.This brake mode can greatly improve the temperature of wheel at glancing impact, and is bigger to the abrasion influence of intensity, wheel tread and the wheel rim of wheel, thereby influences the service life of wheel.
Goal of the invention
Technical matters to be solved by this invention provides a kind of shaft-mounted disc brake device, with the abrasion influence of bogie truck brake equipment in the reduction braking procedure to temperature, intensity, wheel tread and the wheel rim of wheel, the service life of improving wheel.
For solving the problems of the technologies described above, the invention provides the shaft-mounted disc brake device of a kind of bogie truck, it is characterized in that: brake unit is hung on the braking flap seat of truck end sill, makes Moving plate on the axletree during wheel is formed axle box, leaves the gap between the brake unit brake lining of brake disc and its both sides.
Brake unit comprises bearing, cylinder body, clamp lever, brake cylinder, brake lining, bearing and cylinder body are hung by bearing pin, a clamp lever is respectively arranged in the cylinder body both sides, clamp lever one end is fixed on the propelling rod of hydraulic actuating cylinder, an other end is installed brake plate support, the brake lining of braking usefulness just is fixed on the brake plate support, and propelling rod is connected with brake cylinder.
Brake unit is suspended on the inside of bogie truck end carriage, adapts to various gauge requirements.
The present invention is by the braking of brake unit to brake disc, reduced in the braking procedure bogie truck brake equipment to the abrasion influence of temperature, intensity, wheel tread and the wheel rim of wheel, the service life of having improved wheel; In addition, the brake unit among the present invention is suspended on the inside of bogie truck end carriage, and gauge is not had special requirement yet.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the brake unit structural representation.
The specific embodiment
With reference to Fig. 1, brake unit 1 is hung on the braking flap seat 4 of truck end sill 3 by 4 bolts 2; Brake disc 5 is installed on the axletree of wheel to axle box composition 6.
With reference to Fig. 2, the installation of brake unit realizes that by four bolts hole on the bearing 7 whole cylinder body 8 all is suspended on the bearing 7, connects by bearing pin 9; A braking clamp lever 10 is respectively arranged at the two ends of cylinder body 8, one end of clamp lever 10 is connected with propelling rod 11, and the other end is connected with brake plate support 12, and brake plate support is used for fixing the brake lining 13 of braking usefulness, propelling rod links to each other with brake cylinder 14, is used to transmit the retrothrust that brake cylinder produces.
During work, service braking admission port 15 is connected with reservoir on the car, when train is implemented glancing impact, the brake cylinder action promotes propelling rod, propelling rod links to each other with braking clamp lever, the effect of power, is applied on the brake disc by the brake lining that is fixed on the brake plate support to brake plate support by the clamp lever transmission again, thereby realizes the car load braking.
