Description

BACKGROUND OF THE INVENTION The present invention relates to a hand braking device for rail vehicle braking units in which the brake unit cylinders and the hand brake levers and flexible actuators connected thereto are arranged in a floating and positionally variable manner, wherein the central hand brake draw is provided in the longitudinal axis of the bogie.

It is well known that disc brakes and / or delay brake units are used for braking railway vehicles. Each brake unit is associated with a cylinder which is generally mounted in the brake unit housing or on the chassis frame. The brake units are operated by the parking brake centrally from the wagon body.

There is known, for example, according to German Patent No. 82 484, a hand brake linkage in which the draw-off point is located in the longitudinal axis of the bogie, and by connecting links, e.g. levers, linkages and traction clutches, the hand brake is connected to the brake cylinders to each brake unit. The parking brake is actuated by a tractive force. acting on this hand brake connection.

Furthermore, it has already been proposed according to the prior art to provide a disc brake such that the brake cylinder and the hand brake lever connected thereto are arranged in a floating and positionally variable manner, subject to additional adjustment under wear. j

The disadvantage of this construction of the disc brake unit is that the parking brake control cannot be performed with only one rod chain. Accordingly, a flexible component is selected as the actuator, but without suggesting a specific solution, so that, using the idea of the invention, new possibilities have been offered in the choice of technical means, as well as their design and arrangement for the hand brake device.

It is an object of the present invention to provide a handbrake device for braking units with floating and positionally variable brake cylinders.

The object of the invention is to provide a hand brake. a device that provides the same braking force exerted manually on all braking units at a favorable parking brake efficiency that compensates and adjusts the tolerances and expansion of components; adjustable without play and applicable to various chassis designs, in particular to various chassis designs brake systems, without significant changes. *

According to the invention, this object is achieved by hand and brake devices for the brake units of rail vehicles in which the brake unit cylinders and the handbrake levers connected thereto are flexible _; the controls are arranged in a floating and positional manner, the central engagement of the parking brake being

They are symmetrical in the bearing locations of the bogie by means of a connecting link; the part connected to the draw beam, which is horizontally swiveling, partly against each other-movable-! the same length of tension and compression elements to the hand chin, wherein the reciprocating levers of both the wheelset and the wheelset are directly connected to the pulling elements 1 and the reciprocating levers of the other wheelset to the push members.

A further solution according to the invention consists in providing shaped joints and corresponding stops on the chassis cross member on the chassis frame; shaped joints - catch and close. . ,
