Description

Linkage, cometing accel pedal with throttle valve

The present invention relates to a link gauge connecting an accelerator pedal and a throttle valve, and in particular, a separate cover is installed to prevent foreign matter from entering between the shaft and the bushing, and the shaft does not wear even when used for a long time. It is related with the link gauge which prevented the friction sound of the liver.

In general, when the driver steps on the accelerator pedal, the output of the engine is controlled by controlling the amount of air supplied to the engine as the throttle valve opens and closes according to the depression amount of the accelerator pedal. It is a link gauge.

1 to 3 show a conventional link gauge,

A first lever 2 and a second lever 3 are formed at both ends of the rod-shaped shaft 1, respectively, the first lever 2 being connected to the accelerator pedal and the first rod 2a. Connected, the second lever 3 is connected to a second rod 3a which is connected to a throttle valve, each of the first and second levers 2 and 3 facing each other with respect to the shaft 1. It protrudes in the direction to become.

The shaft 1 is fixed by the first plate 4 and the second plate 5 fixed to the vehicle body, and a separate bushing 6 is provided between the plates 4 and 5. It is installed so that the shaft 1 can rotate independently with respect to each plate 4, 5.

The contact surface between the shaft 1 and the bushing 6 is coated with a lubricating member 7 such as grease so that the rotating shaft 1 and the bushing 6 are not worn.

Referring to the operation of the conventional link gauge configured in this way,

When the driver presses the accelerator pedal, the force is applied to the first lever 2 while the first rod 2a is pulled or pushed.

This force causes the shaft 1 to rotate in a constant direction. As the shaft 1 rotates, the second lever 3 rotates and pulls or pushes the second rod 3a, thereby controlling the opening and closing amount of the throttle valve. Will be.

However, in the conventional link gauge, since the shaft 1 and the bushing 6 are open, when the link gauge is used for a predetermined time, foreign matter gets caught in the gap between the shaft 1 and the bushing 6, and the foreign matter. By the lubrication member applied between the shaft 1 and the bushing 6 is not functioning properly, the shaft 1 is easily worn, and the wear of the shaft 1 causes the user to operate the accelerator pedal every time. Friction between the shaft 1 and the bushing 6 occurs, causing a problem for the driver.

In addition, since the shaft 1 and the bushing 6 are open, a problem arises in that the lubrication member applied thereon is easily dried and does not function properly.

Accordingly, the present invention for solving the above problems is to install a separate cover so that foreign matter does not enter between the shaft and the bushing link so that the shaft does not wear even during long-term use, the friction noise between the parts during operation of the accelerator pedal The purpose is to provide a gauge.

Features of the present invention for achieving the above object,

A first lever coupled to the first pedal connected to the accelerator pedal and a second lever coupled to the second rod connected to the throttle valve of the engine are respectively installed at both ends of the shaft, and the shaft protrudes upward and downward. In the link gauge which is supported by the first and second plates fixed to the vehicle body and transmits the response input of the accelerator pedal to the throttle valve,

Bushings respectively provided between the first and second plates and the shaft,

A bearing installed between the bushing and the shaft to allow the shaft to rotate independently of the bushing;

The cover is coupled to both sides of the bushing and configured to block foreign matter from entering the bushing.

The first and second levers are coupled to the shaft as bolts, and the bearings are hemispherical bearings formed integrally with the shaft, and a guide part formed at the inner center of the bushing is formed in a streamlined shape to be joined with the bearings. It features.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 4 and 5.

According to the figure, the present invention is roughly composed of first and second levers 11 and 12, bushings 13 and covers 15.

The first and second levers 11 and 12 are connected to the accelerator pedal and the throttle valve, respectively, and the first lever 11 is coupled to the first rod 2a connected to the accelerator pedal. The second lever 12 is coupled to the second rod 3a which is connected to the throttle valve.

Each of the levers 11 and 12 is coupled to both ends of the shaft 1 supported by the first and second plates 4 and 5, and is manufactured by being detached by a separate bolt 16. To facilitate this, each lever 11, 12 projects in a direction opposite to each other with respect to the shaft 1.

A bushing 13 is installed between the shaft 1 and each of the plates 4 and 5, and a guide portion 13a protrudes from the inner center of the bushing 13, and a hemispherical shape is formed on the shaft 1. The bearing 14 protrudes and is formed to engage with the guide portion 13a.

That is, the bottom surface of the guide portion 13a is formed to be curved in a streamlined shape so that the bearing 14 can be coupled so that the bearing 14 rotates in a state joined to the guide portion 13a, and the guide portion ( A lubrication member is applied between 13a) and bearing 14.

The cover 15 is formed on both sides of the bushing 13 to block foreign matter from entering the bushing 13. As shown in FIG. 4, one side is coupled to one side of the bushing 13 and the other side. The side was formed to be in close contact with the outer circumferential surface of the shaft 1 so that the inside of the bushing 13 is completely sealed.

When the inside of the bushing 13 is completely sealed by the cover 15 as described above, foreign matter does not penetrate into the bushing 13 even if the link gauge is used for a long time, so that it is applied between the bearing 14 and the guide part 13a. The lubricating member can function for a long time, so that the bearing 14 and the guide portion 13a are not easily worn.

In addition, since the inside of the bushing 13 is completely sealed by the cover 15, the additional effect that the lubrication member applied between the bearing 14 and the guide portion 13a is not easily dried can also be expected.

In addition, since the first lever 11 and the second lever 12 may be coupled to both sides of the shaft 1 as bolts 16, the first and second levers 11 and 12 are conventionally used when welding the first and second levers to the shaft 1. Since a separate jig is not required, productivity can be improved by reducing production cost and simplifying a work process, and it is possible to prevent thermal deformation of a lever or shaft generated during welding.

As described above, the present invention is a link gauge in which a separate cover is installed to prevent foreign matter from entering between the shaft and the bushing so that the shaft is not worn even when used for a long time, and the friction sound between components does not occur during operation of the accelerator pedal.
