    • A vane pump has a casing, a controlling collar guided leaktightly in the casing and movable relative to a rotor mounted in the casing and surrounded by the controlling collar. The movement of the collar is transverse to the axial direction of the rotor. A suction region of the pump is defined by a volume increasing in the direction of rotation of the rotor, of a vane cell formed between two adjacent vanes and decreasing to the pressure region. At least one adjustment member is provided to adjust the position of the controlling collar in dependence on the prevailing pumping parameters. In order to provide a vane pump of space-saving and/or simple and cost-saving design, at least one recess is open towards the outside of the controlling collar and is provided on the controlling collar close to the pressure region to accommodate and adjustment member.

    • A method is described for determining brake coefficients, which define the relationship between the brake pressure and the brake force at a wheel or axle of a motor vehicle or of a section of a vehicle combination during the braking operation of the vehicle or vehicle combination. During the braking operation of vehicle, the wheel speed and the brake pressure are determined measurement/time intervals with differing brake pressure distribution between the wheels, axles or vehicle sections are formed, in which the equilibrium of forces between the brake force and the force of inertia of the motor vehicle is obtained. The mass-related brake coefficients of the brake-pressure-sensed wheels or axles and a mean value for the mass-related brake coefficient of all non-brake-pressure-sensed wheels or axles are determined from the equations for the equilibrium of forces in the measurement/time intervals; by forming the quotient between these mass-related brake coefficients, the relative brake force development of the individual axle (or of the individual section of the vehicle combination), i.e. its respective proportion of the total brake force sum, can be determined without the need to know vehicle-specific design data or the total mass.
    • 描述了一种用于确定制动系数的方法,其限定了在车辆或车辆组合的制动操作期间制动压力和机动车辆的车轮或车轴或车辆组合的部分之间的制动力之间的关系。 在车辆的制动操作期间,确定车轮速度和制动压力的测量/时间间隔,在车轮之间形成不同的制动压力分布,形成车轴或车辆部分,其中制动力和制动力之间的力平衡 获得机动车辆的惯性。 制动压力感测车轮或车轴的与质量有关的制动系数以及所有非制动压力感测车轮或车轴的质量相关制动系数的平均值由等式 测量/时间间隔; 通过在这些质量相关的制动系数之间形成商,可以确定单独轴(或车辆组合的单独部分)的相对制动力显现,即其总制动力总和的相应比例,而不需要 了解车辆特定设计数据或总质量。
