Abstract
An actuating pedal (1) for the brake system of a road vehicle has a fastening device (6) for fixing the actuating pedal (1) in a pivot bearing (12) on a pedal block (7) of the vehicle. The pedal block is a rigid part of the body, with a pedal body (2) and with an actuating surface (3). The pedal body (2) has at least one inner metal core (8) and a plastic jacketing (9) surrounding the metal core (8).
Claims16
A road vehicle brake system actuating pedal for connection to a pivot bearing on a pedal block of the vehicle and for connection to a brake system connection device, the pedal block being a rigid part of the vehicle body, the actuating pedal comprising:
- a fastening device for fixing the actuating pedal to the pivot bearing;
- a pedal body;
- and
- a pedal plate having an actuating surface, said pedal body extending from said pedal plate to the fastening device and the pivot bearing, said pedal body having at least an inner metal core and with a plastic jacketing surrounding said metal core, said pedal body having a connection to the brake system connection device, said inner metal core and said plastic jacketing surrounding said metal core cooperating to transmit torsional forces with said inner metal core and said plastic jacketing surrounding said metal core both together contributing to a torsional rigidity of the actuating pedal from the pedal plate to the connection and from the connection to the fastening device.
A road vehicle brake system, comprising:
- a pivot bearing on a vehicle pedal block with a pivot bearing, the pedal block being a rigid part of the vehicle body;
- a brake to brake pedal connection device;
- an actuating pedal with a fastening device for fixing said actuating pedal to the pivot bearing, with a pedal body and with a pedal plate having an actuating surface, said pedal body extending from said pedal plate to the fastening device and the pivot bearing, said pedal body having at two inner metal cores and a plastic jacketing surrounding said metal cores, said pedal body having a connection to the brake system connection device, said inner metal cores and said plastic jacketing surrounding said metal cores cooperating to transmit torsional forces with said inner metal cores and said plastic jacketing surrounding said metal core both together contributing to a torsional rigidity of the actuating pedal from adjacent to the pedal plate to the connection to the brake system connection device and from the connection to the brake system connection device to the fastening device, wherein said fastening device is made in one piece with said plastic jacketing.
A road vehicle brake system, comprising:
- a pivot bearing on a vehicle pedal block with a pivot bearing, the pedal block being a rigid part of the vehicle body, the pedal block having a cam path;
- a brake power booster module;
- a brake power booster module connection device;
- an actuating pedal with a fastening device for fixing said actuating pedal to the pivot bearing, with a pedal body and with a pedal plate having an actuating surface, said pedal body extending from said pedal plate to the fastening device and the pivot bearing, said fastening device having a pin element with a free end facing away from said fastening device and a spring-tensioned pressure roller rolling on said cam path, said pedal body having at two inner metal cores and a plastic jacketing surrounding said metal cores, said pedal body having a connection to the brake system connection device, said inner metal cores and said plastic jacketing surrounding said metal cores cooperating to transmit torsional forces with said inner metal cores and said plastic jacketing surrounding said metal core both together contributing to a torsional rigidity of the actuating pedal from adjacent to the pedal plate to the connection to the brake system connection device and from the connection to the brake power booster module connection device to the fastening device, wherein said fastening device is made in one piece with said plastic jacketing.
