Pedal for vehicle capable of adjusting pedal effort by use of detent
A pedal includes a pedal effort adjuster configured to generate pedal effort in response to an increase in stroke of a pedal arm, where the pedal effort adjuster includes a detent spring for generating the pedal effort by load of the detent spring that is decreased after being increased in response to a change in reaction force caused by the increase in stroke and a return spring for generating the pedal effort by load of the return spring that is increased by maintaining reaction force caused by the increase in stroke.
1. A pedal, comprising:
a pedal effort adjuster configured to generate pedal effort in response to an increase in stroke of a pedal arm,
wherein the pedal effort adjuster further comprises:
a detent spring for generating the pedal effort by load of the detent spring that is decreased after being increased in response to a change in reaction force caused by the increase in stroke;
a return spring for generating the pedal effort by load of the return spring that is increased by maintaining reaction force caused by the increase in stroke;
a piston coupled to one end of the pedal arm to compress the detent spring; and
a main member configured such that a guide inner surface of a guide rail for changing a height of the piston is coupled thereto and the main member is covered and concealed with a cover,
wherein the main member and the guide rail are connected to each other via coupling protrusions.
2. The pedal according to claim 1 , wherein the reaction force of the detent spring is changed by the piston.
3. The pedal according to claim 2 , wherein the detent spring is installed within the pedal arm.
4. The pedal according to claim 2 , wherein the piston has a round shape at its outside end.
5. The pedal according to claim 4 , wherein the piston is configured to be inserted into the one end of the pedal arm and coupled thereto in a protruding state.
6. The pedal according to claim 2 , wherein the piston contacts with the guide inner surface of the guide rail.
7. The pedal according to claim 6 , wherein the guide inner surface of the guide rail divides a contact movement path of the piston into a plurality of paths to make the change in the reaction force.
8. The pedal according to claim 7 , wherein the guide inner surface of the guide rail is configured such that the contact movement path is formed in a straight line.
9. The pedal according to claim 7 , wherein the guide inner surface of the guide rail is configured such that the contact movement path is formed in a curved form.
10. The pedal according to claim 7 , wherein the guide inner surface of the guide rail is configured such that the contact movement path is formed in a circular arc shape.
11. The pedal according to claim 1 , wherein the pedal arm is rotatably coupled to the main member.
12. The pedal according to claim 11 , wherein the main member and the guide rail are directly connected to each other.
13. The pedal according to claim 1 , wherein the main member and the cover are connected to each other via protrusions.
