AI Technical Summary

Problems solved by technology

However, due to the complex link between the coefficient of adhesion and external conditions, such a maximum value is no longer easy or reliable to determine, for example because of an incorrect curve of the coefficient of adhesion-wheel slip function
This can lead to inefficient wheel braking, resulting in longer stopping distances

Embodiment Construction

[0022] figure 1 A schematic diagram showing the distribution of wheel slip of a rail vehicle 10 , which in this example comprises a first vehicle bogie 12 and a second vehicle bogie 14 . The vehicle truck 12 has a first wheel set 16 and a second wheel set 18 . The second vehicle bogie 14 has a third wheel set 20 and a fourth wheel set 22 . These wheel sets each have wheels connected to one another via a common axle. Therefore, the wheels of a wheel set cannot rotate independently of each other, however, the wheels of different wheel sets can rotate independently of each other. Below the schematic representation of the rail vehicle 10 , different distributions of the target slip value ranges associated with the individual wheel sets are shown. The adhesion coefficient-wheel slip function associated with each wheel set is shown in the four rows A, B, C and D respectively. Here, the coefficient of adhesion is described schematically via wheel slip. In the same row, the same ...

Abstract

The invention relates to a brake regulation device (51) for a rail vehicle (10), which device is or can be connected to at least one first brake device (56) and a second brake device (58) for controlling purposes, the first brake device (56) being suitable for braking at least one first wheel (52) of the rail vehicle (10) and the second brake device (58) being suitable for braking at least one second wheel (54). The first wheel (52) and the second wheel (54) are capable of independent rotation. The brake regulation device (51) is designed to regulate the first brake device (56) and the second brake device (58) independently of one another and is capable of determining and / or recording the actual slip of the first wheel (52) and the actual slip of the second wheel (54). The brake regulation device (51) is also designed to regulate the first wheel (52) to achieve a pre-determined first target slip value, by actuating the first brake device (56) and to regulate the second wheel (54) to achieve a pre-determined second target slip value that differs from the first target slip value, by actuating the second brake device (58). The invention also relates to a brake system (50) comprising a brake regulation device (51) of this type, to a rail vehicle (10) and to a method for regulating a brake system (50).

Description

technical field [0001] The invention relates to a brake adjusting device for a rail vehicle, a brake system having such a brake adjusting device, a rail vehicle and a method for adjusting a brake system of a rail vehicle. Background technique [0002] When braking a rail vehicle by means of a friction brake device, there is basically the problem that the forces provided for braking the vehicle have to be absorbed by the contact between the wheel and the rail. The ability of the contact between the wheel and the track to withstand forces is often described by a parameter known as the coefficient of adhesion or adhesion. The coefficient of adhesion, in particular, can vary significantly depending on the external environment. For example, it is possible here to determine whether and which intermediate layers are formed between the wheel and the track. In addition to this, the coefficient of adhesion depends on the wheel slip S, which describes the difference between the vehic...
