Embodiment Construction

[0044] according to figure 1 and 2 The graphs of , respectively, show the maximum lever travel for disc brakes at different temperatures or at different speeds as a function of brake pressure. It shows that the individual maximum lever distances, brake pressure, temperature and speed are interrelated or dependent on each other. Rod path is a measure for clearance.

[0045] as can especially be obtained from figure 1 At a brake pressure of 10bar and a speed of 40km / h, the maximum lever travel

[0046] 61mm at a temperature of 100°C,

[0047] 60mm at a temperature of 300°C, and

[0048] It is 57.5mm at a temperature of 500°C.

[0049] according to figure 2 , when the brake pressure is 10bar and the temperature is 500℃, the maximum rod travel

[0050] 58mm at a speed of 40km / h,

[0051] 64mm at a speed of 80km / h, and

[0052] It is 64.5mm at a speed of 120km / h.

[0053] The temperatures are each the temperature of one of the participating brake linings. Since the bra...

Abstract

The invention relates to a method for monitoring a brake wherein the air play of the brake is measured and there is found to be an error if the air play of the brake falls below a lower threshold value or exceeds an upper threshold value. According to the invention, the lower and / or the upper threshold value is / are variable, in dependence on at least one momentary or past operating state parameter influencing the air play. The invention further relates to a brake, in particular for utility vehicles, which is monitored by the cited method.

Description

technical field [0001] The invention relates to a method for monitoring a brake, wherein the play of the brake is measured and a fault is concluded if the play of the brake falls below a lower limit value or exceeds an upper limit value. Background technique [0002] Such a method is known, for example, from EP2520817A1. As a result, a warning display is triggered not only when the setpoint air gap is exceeded but also when it is undershot. Brake signals and brake pressure signals are supplied to a controller provided in the known brake for detecting the operating state of the brake system. These signals are only taken into account for the purpose of ascertaining the operating state, ie whether the brake is engaged or released. [0003] DE 42 12 407 A1 discloses a play detector for a compressed-air operated disc brake, in which a rotational angle sensor is used to measure the play. According to WO 2010 / 005379 A1, the clearance is determined from the lever path and the pre...
