Pedal for a motor vehicle
A pedal for a motor vehicle is provided, having a pedal arm with at least one first resetting spring and with a friction system comprising a separate friction element and a friction surface of the base part corresponding to the separate friction element. The friction system features a rocker arranged in a rotatable manner on the base part and the at least one first resetting spring is arranged between the separate friction element and the rocker. The separate friction element is connected in a pressure-transmitting manner with the pedal arm by the at least one first resetting spring and at least one connection element. At least one second resetting spring is arranged between one bearing part connected in a pressure-transmitting manner with the pedal arm by the at least one connection element and the base part or the rocker.
1. A pedal for a motor vehicle, the pedal comprising:
a base part;
a pedal arm rotatably mounted about a first rotary axis, wherein the pedal arm is moveable between a resting position and a maximum actuating position;
a connection element including a proximal end coupled to the pedal arm and a distal end positioned and located opposite from the proximal end;
a bearing part rotatably coupled to the distal end of the connection element and rotatably coupled to the base part about a second rotary axis;
a resetting spring extending from the base part to the distal end of the connection element;
a friction system including:
a friction element in mechanical communication with the distal end of the connection element;
a rocker rotatably coupled to the base part about a third rotary axis, the rocker including a first end and a second end;
a friction system spring extending from the distal end of the connection element to the first end of the rocker; and
wherein when the pedal arm is moved from the resting position to the maximum actuating position, the rocker rotates such that the second end of the rocker pushes the friction element into contact with a surface on the base.
2. The pedal in accordance with claim 1 , wherein when the friction system is functioning properly, the friction element is in a force transmission connection with the pedal arm merely by the friction system spring and the connection element.
3. The pedal in accordance with claim 1 , wherein the resetting spring is designed such that when the friction system is not functioning properly, the pedal arm can be automatically transferred into the resting position when the pedal arm is not being actuated.
4. The pedal in accordance with claim 1 , wherein the friction element and the bearing part extend essentially parallel to each other and are arranged directly adjacent to each other.
5. The pedal in accordance with claim 1 , wherein the bearing part is a sensor part by means of which a rotation angle of the pedal arm relative to the base part can be determined.
6. The pedal in accordance with claim 1 , wherein a spring force line of action of the resetting spring and a spring force line of action of the friction system spring are arranged substantially parallel to each other.
7. The pedal in accordance with claim 1 , wherein at least one of the resetting spring and friction system spring is a double spring.
