Description

Pedal for vehicle {PEDAL FOR VEHICLE}

The present invention relates to a vehicle pedal including a clevis capable of changing a clevis point position.

In general, a vehicle includes a clutch installed between a flywheel and a transmission and controlling the power of an engine to be transmitted as needed. The clutch cuts off the connection with the engine when starting the engine or when shifting gears, and performs a function of gradually connecting the power of the engine when the vehicle starts.

Recently, a vehicle is configured to have various displacements of one vehicle type in consideration of various needs of consumers. When the engine displacement changes, the force to control the clutch for shifting increases, and the force to press the clutch pedal must also increase.

However, since the pedal effort of pressing the clutch pedal of all vehicles needs to be maintained constant, the pedal force is maintained constant by changing the pedal ratio.

The pedal ratio of vehicle pedals (clutch pedal, brake pedal, and accelerator pedal) is the distance between the pedal hinge shaft of the pedal arm and the connecting part (clevis point) between the booster rod or the master cylinder rod, and the pedal hinge of the pedal arm. It is determined by the ratio of the distance between the shaft and the pedal pad.

When producing a vehicle, the pedal ratio, once determined, does not change, forming a fixed pedal ratio of the pedal. When the vehicle pedal in which each component is assembled with each other is installed in the vehicle, the driver must operate the vehicle pedal having a fixed pedal ratio to a specific value regardless of his or her physical condition.

As a method for changing the pedal ratio, there is a method by the driver, but in this case, the driver must move and operate the seat on which the driver sits so that the distance between the pedal with the fixed pedal ratio and the driver's own is adjusted.

There is a method of changing the position of the pedal hinge in a way that allows the driver to change the pedal ratio without directly pulling or pushing the seat.

In order to change the point of the pedal hinge, it is necessary to additionally produce a mold for manufacturing the pedal member and the pedal arm corresponding to the changed pedal ratio. Manufacturing new molds for different pedal ratios incurs excessive new development investment costs.

There is a method of changing the position of the clevis point rather than the point of the pedal hinge as a method of changing the pedal ratio with minimal change.

Changing the clevis point also requires producing a piercing mold that creates a hole for mounting the clevis on the pedal arm. Therefore, there is a need for a technology that can change the clevis point without the production of a new mold.

The present invention provides an improved vehicle pedal so that the pedal ratio can be changed by changing only the position of the clevis point of the vehicle pedal.

The present invention provides an improved vehicle pedal to apply a plurality of clevis pins.

In general, since the clevis ball 220 is installed on the clevis pin 210 , in order to change the position of the clevis ball 220 , the position of the clevis pin 210 may also need to be changed.

In the vehicle pedal 100 according to the present invention, the clevis ball 220 may be installed on the rod 150 rather than the clevis pin 210 . Since the clevis ball 220 is installed on the rod 150 , the position of the clevis ball 220 can be changed regardless of the clevis pin 210 .

The clevis ball 220 may be detachably attached to the plurality of clevis pins 210 by pushing one end of some of the clevis pins 210 to change their positions.

The clevis ball 220 has a spherical shape, and among the plurality of clevis pins 210 that are not pushed by the clevis ball 220 , a fixing groove of some clevis pins 210 in contact with the clevis ball 220 . The clevis ball 220 may be fixed to the 213 .

The fixing groove 213 may have an arc shape to correspond to the clevis ball 220 having a spherical shape.

The diameter of the fixing groove 213 may be smaller than the diameter of the clevis ball 220 . When the clevis ball 220 having a relatively large diameter is inserted into the fixing groove 213 having a relatively small diameter by an external force, the clevis ball 220 may be fixed without being separated by a minute difference in diameter.

The position of the clevis ball 220 coupled to the plurality of clevis pins 210 may be changed.

Within the area formed by the plurality of clevis pins 210 accommodated in the pin space 257, the clevis ball 220 can freely change the detachable position.

When the clevis ball 220 is detached from the previously mounted position by an external force, some clevis pins 210 pushed out by the clevis ball 220 may return to their original position.

The clevis pin 210 may return to its original position by the elastic force of the clevis spring 230 provided at the other end of the end where the clevis ball 220 comes into contact with the clevis pin 210 .

The clevis spring 230 may also perform a function of holding the clearance between the clevis ball 220 and the plurality of clevis pins 210 .

When all of the plurality of clevis pins 210 return to their original positions, by mounting the clevis balls 220 to some other clevis pins 210 accommodated in arbitrary positions of the pin space 257, clevis points can be changed.

By freely changing the position at which the clevis ball 220 is mounted in the pin space 257 accommodating the plurality of clevis pins 210 . The second distance (not shown) between the rod 150 connected to the clevis ball 220 and the pedal hinge 140 may be changed.

When the second distance (not shown) is changed, the pedal ratio can be changed, so that only the clevis point can be changed without changing the first distance (not shown) between the pedal pad 110 and the pedal hinge 140 . .

By changing the clevis point through a simple structure, it is possible to implement a pedal ratio corresponding to various displacements in one vehicle 1 .

Although the technical idea of the present invention has been described above by way of specific embodiments, the scope of the present invention is not limited to these embodiments.

Various embodiments that can be modified or modified by those of ordinary skill in the art within the scope not departing from the gist of the present invention specified in the claims are also included in the scope of the present invention. will be.
