Embodiment Construction

[0026] figure 1 An exemplary embodiment of the braking device 1 according to the invention is shown schematically. The brake device 1 has a plurality of brake cylinders 2 which are arranged in a pivot strut of a rail-guided vehicle (not shown). The brake cylinder 2 comprises a brake chamber which can be filled with compressed air and which is separated in a sealed manner by a movably guided piston. The piston is connected to a piston rod, which in turn is connected to at least one brake pad via a suitable lever mechanism, wherein each brake pad faces a brake disc. In order to start the braking process, the brake cylinders or rather the brake chambers are pressurized, the pistons separating the brake chambers are moved and each brake pad is pressed against the brake disc in frictional contact. The brake disk is connected in a rotationally fixed manner to the likewise not shown axle, so that the rotating strut and thus the rail-guided vehicle are decelerated. The deceleration...

Abstract

In order to provide a brake device (1) for braking a vehicle which has a brake surface which is rotationally fixedly connected to a wheel axle of the vehicle, having a brake lining which can be pressed with a braking force against the brake surface and having an actuating element (2), which is coupled to a control unit (3), for generating the braking force, wherein the control unit (3) is connected to a speed sensor for measuring a speed of the vehicle and is set up to adjust the braking force as a function of the speed, by means of which brake device (1) as high a braking force as possible is introduced into the brake surfaces, it is proposed that the control unit (3) is coupled to the actuating element (2) via means for continuous pressure adjustment (4), so as to enable a continuous adaptation of the braking force to the present speed in each case. The braking force is advantageously adjusted inversely proportionally to the speed of the vehicle.

Description

technical field [0001] The invention relates to a braking device for braking a vehicle having a braking surface connected in a rotationally fixed manner to the wheel axle of the vehicle, the device having a brake pad which can be pressed onto the braking surface by a braking force and an adjustment A unit-coupled control element for generating a braking force, wherein the regulating unit is associated with a speed sensor for detecting the vehicle speed and is designed to adjust the braking force as a function of the speed. [0002] Furthermore, the invention also relates to a method for braking a vehicle, in which the speed of the vehicle is detected by a speed sensor, and a regulating unit connected to the speed sensor presses the brake pads against the wheel axle of the vehicle with a braking force according to the speed Braking surfaces connected in a rotationally fixed manner. Background technique [0003] Such a braking device and such a method are already known from D...
