    The invention relates to devices for controlling the braking process.
    The aim of the invention is to simplify the design.
    Fig. 1 shows a setting device, a first embodiment; figure 2 - the same, the second option; on fig.Z - the same, the third option.
    The gauge (figure 1) consists of a mounting plate 1, an U-shaped curved leaf spring 2 installed on it, at least one bend 3 sensor of the leaf spring 2, limiting the bend of the leaf spring 2 of the rack 4 with an emphasis 5, as well as on the leaf spring 2 of the pedal 6. The mounting plate 1 is installed in a suitable place of the vehicle on the bottom sheet 7. The pedal 6 is controlled by the driver by the force F of the foot. The sensor 3 detects the bending of the leaf spring 2. To do this, a plate-shaped tensometer 8 is mounted on the leaf spring 2. However, other measurement principles can also be used. So, for example, the path of the bending leaf spring 2 can be determined by a displacement sensor of known design. As a displacement sensor, for example, a potentiometer or a coil with a moving core can be used. In the latter case, the fixed part of the sensor is mounted on the mounting plate 1. The bending of the leaf spring 2 can also be determined optically, for example by means of a light gate. This can also be accomplished by intermediately turning on the fiber, which has the advantage that the electronic unit for processing and amplifying the control signal does not have to be installed directly on the sensor. Sensor 3 is housed in housing 9 and has an evil coupling 10. I
    Sensor 3 provides a force dependent or displacement electrical output signal that can be used, for example, to control an electrical braking device.
    In order to always bend the leaf spring 2 within elastic limits, a support 5 is mounted on a stand 4 fixed to the mounting plate 1, which serves to limit the movement of the leaf spring 2.
    Figure 1 shows the inoperative position of the leaf spring. The stroke a corresponds to the pressure affecting the brake from O to PM /) KS, the stroke and the allowable stroke specified by the material of the spring 2, the stroke S to the allowable stroke in the opposite direction.
    Due to the stop 5, the leaf spring 2 cannot exceed the elastic limit as a result of the impact on non-forces. As a consequence, a strain gauge 8 or other voltage sensor can be subjected to a load of a relatively large absolute voltage, since its operating limit can reach almost to the limit of elasticity.
    Due to the shape of the leaf spring 2 or by stamping, it is also possible to progressively increase the forces along the path of movement, as with cup springs (not shown).
    For leaf springs 2, spring steel is commonly used, if necessary, stainless spring steel. However, it is also possible to use, for example, glass fiber reinforced plastic. It is easier to obtain the necessary form of implementation, for example, a variable thickness.
    The housing 9 may further comprise an electronic integrated unit for amplifying and processing the signal of the leaf spring bend sensor.
    Since the housing 9 with the sensor 3 and the integrated electronic unit is installed in the inner zone of the curved section of the leaf spring 2, the sensor 3 is protected from external mechanical action.
    The multi-gradient sensor of the brake value and the monitoring of the sensor function can be ensured by placing several bend sensors on the leaf spring 2. In this case, depending on the requirements, you can use active (control) and inactive (control) bend sensors. The active sensors control through amplifiers the control valves belonging to the individual braking circuits. Inactive bend sensors serve only to compare or monitor active bend sensors.
    The second embodiment of the setting devices (Fig. 2) differs from the first one (Fig. 1) by a different kind of influence of the driver's leg F on the leaf spring.
    51
    Well 2. The force of the leg acts on the pedal 6, hinged on the plate 1. On the pedal 6, the role 11 is set, moving along the leaf spring 2.
    According to the third embodiment (FIG. 3), the driver's foot F is transmitted through the lever 12 pivotally mounted on the upper end of the rack 4. The movement of the lever 12 is transmitted through the connecting element 13 to the leaf spring 2.
    The supply of force according to the second and third variants provides greater stability of the forces on the leaf spring 2. In this case, influence on the characteristics of force and displacement is possible due to the corresponding implementation of the hinge geometry.
