Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an accelerator control cable bracket that is used in an accelerator link device that transmits accelerator input to a throttle and supports a cable cover that slidably guides a longitudinally intermediate portion of an accelerator cable.

When attaching an autodrive device (constant speed driving device) that controls the vehicle speed to a predetermined value to an accelerator link device that transmits accelerator input from the automobile's accelerator pedal to a throttle such as a carburetor using a control cable, A pulley is provided in the middle.

In other words, this pulley is rotated by accelerator input from the accelerator pedal, and another control cable that connects this pulley to the throttle of the carburetor, etc. is wound around this pulley to rotate the throttle shaft in the opening direction. .

Also, when the auto drive device's set switch is activated, driving force such as engine negative pressure is transmitted to this pulley via a control cable, etc.
This also causes the throttle shaft to rotate in the opening direction. The driving force generated by this engine negative pressure controls the throttle opening by rotating a pulley by the necessary amount calculated by a computer based on the set vehicle speed, actual vehicle speed, engine speed, etc.

However, with this type of accelerator link device,
When used in an engine designed with a different cable wiring position from the pulley to the throttle, the relative positional relationship between the pulley and the throttle will change.
It is conceivable that the cable wiring may be forced to bend unnecessarily, resulting in a decrease in durability and operational feel. Another problem is that the cable passes above the oil filler cap on the engine cover, reducing work efficiency during oil changes.

The accelerator cable is covered with a cable cover that slidably guides its longitudinal intermediate portion, and this cable cover is supported by a bracket provided adjacent to the pulley to determine the take-out angle from the pulley. There is.

Therefore, it is conceivable to prepare a plurality of types of brackets corresponding to designs with different cable wiring positions and use the brackets according to the take-out angles.

However, preparing multiple types of brackets is extremely disadvantageous in terms of manufacturing costs, assembly costs, inventory management costs, etc.

Utility Model Publications No. 57-7806 and Utility Model Publication No. 51-15880 are known as technologies related to the combination of pulleys and accelerator cables, but even if these technologies are applied, other problems may occur, or this problem may occur. In order to solve this problem, the structure becomes complicated and there is no advantage over preparing multiple types of brackets.

In consideration of the above facts, the present invention aims to enable smooth cable wiring even for engines with completely different accelerator cable wiring using the same accelerator control cable bracket.

The present invention relates to an accelerator control cable bracket that is installed adjacent to a pulley to which one end of an accelerator cable that transmits accelerator input to the throttle is attached, and that supports a cable cover that slidably guides the longitudinally intermediate portion of the accelerator cable. , a plurality of cable cover engaging parts are provided so as to face a plurality of tangent lines to the accelerator cable winding shell of the pulley, and by selecting a cable cover engaging part, the accelerator cable is wound around the accelerator cable winding shell. It is characterized in that the angle at which the accelerator cable is taken out from the pulley can be varied without changing the hooking direction or the position of the bracket.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an electronic fuel injection type engine 10 equipped with an accelerator link mechanism to which an embodiment of the accelerator control cable bracket according to the present invention is applied. A pulley 20 is rotatably supported by a shaft 18 on a bracket 16, in which the engine 10 is placed in the engine room 12 and attached to the body 14, as shown in FIG. An accelerator cable winding shell 22 is formed on this pulley 20 coaxially with the shaft 18. One end of an accelerator cable 24 is attached to this winding barrel 22, and a pulley 2
It is designed to receive zero rotational force.

That is, the pin 26 fixed to one end of the accelerator cable 24 is accommodated in a stopper 28, and this stopper 28 is attached to the end of the winding barrel 22. As a result, the accelerator cable 24 near the pin 26 is connected to both sides of the winding trunk 22 (second
It is arranged in a U-shaped groove formed by the side plate 30 and the winding drum 22, which are arranged in a direction perpendicular to the plane of the drawing.

Therefore, the accelerator cable 24 has a second pulley 20.
When the pin 26 is rotated counterclockwise in the figure, the vicinity of the pin 26 is wound around the winding drum 22, and a tensile force is generated by receiving the rotational force of the pulley 20.

The other end (not shown) of the accelerator cable 24 is connected to a throttle portion such as a throttle lever shaft of a fuel injection device 32 attached to the engine 10, and the throttle opening degree is increased when the pulley 20 rotates.

The outer periphery of the intermediate portion of the accelerator cable 24 is covered with a cable cover 34 . One end of this cable cover 34 is fixed to the bracket 16 with a presser plate 36 as shown in FIG. 2, and the other end is connected to the body of the fuel injection device 32. As a result, when the pulley 20 rotates, the accelerator cable 24 can slide in the longitudinal direction inside the cable cover 34 and transmit the tensile force to the throttle of the fuel injection device 32, so that the middle part of the accelerator cable 24 can be bent. It's summery.

The mounting structure of the cable cover 34 using the presser plate 36 will be described in detail.

A part of the bracket 16 is a mounting plate 38 bent at right angles, and a plurality of U-shaped grooves 40 (two in this embodiment) are formed in this mounting plate 38 as shown in FIG. ing. The surface of each portion of the mounting plate 38 in which the U-shaped groove 40 is formed is perpendicular to the tangent to the winding drum 22 of the pulley 20.

The holding plate 36 is designed to hold a radially protruding collar portion 42 near the end of the cable cover 34 to the mounting plate 38, and is screwed into a screw hole 46 of the mounting plate 38 with a screw 44. This clamping force is generated by this. For this purpose, the holding plate 36 has a circular hole or a U-shaped groove 40 having the same shape as the U-shaped groove 40 into which the cable cover 34 is inserted.
It is preferable that the grooves be provided on both sides of the screw 44.

By this, if the holding plate 36 is fixed to the mounting plate 38 with the screws 44, even when the cable cover 34 is installed in any U-shaped groove 40, the vicinity of the end of the accelerator cable 24 can be fixed in the tangential direction of the winding trunk 22. By arranging this arrangement, the accelerator cable 24 can be smoothly wound around the winding trunk 22 when the pulley 20 rotates.

The pulley 20 also has another accelerator cable 4 covered with a cable cover as shown in FIG.
One end of the accelerator cable 48 is attached (the mounting structure is not shown), and the other end of the accelerator cable 48 is connected to an accelerator pedal (not shown). This allows the accelerator cable 48 to rotate the pulley 20 and apply a tensile force to the accelerator cable 24 when the accelerator pedal is depressed.

Further, the output of a drive device (for example, a motor or a piston generated by engine negative pressure) (not shown) is transmitted to the pulley 20 via a cable, etc., and this drive device is controlled by a computer to maintain the vehicle speed at a set value. is rotated counterclockwise in Figure 2 by the required amount.

In the accelerator control cable mounting structure of this embodiment configured as described above, when the driver depresses the accelerator pedal, the pulley 20 is rotated counterclockwise in FIG. 2 via the accelerator cable 48, so this rotational force is is transmitted as a tensile force to the accelerator cable 24, the throttle of the fuel injection device 32 is opened, and the engine speed increases. When the occupant sets the switch of the autodrive device, the pulley 20 is similarly rotated counterclockwise, and the engine speed similarly increases.

When attaching such a bracket 16 to a different engine 50 as shown in FIG.
4 is attached to the other U-shaped groove 40 of the mounting plate 38 using a holding plate 36. As a result, while the accelerator cable 24 is arranged in the tangential direction of the winding shell 22, the intermediate portion can be smoothly guided to the carburetor below the air cleaner 52, as shown in FIG.
It also does not pass over the oil filler cap 54 of the engine 50.

As a result, even when installing the accelerator cable to a different engine, the same bracket 16 can be installed without changing the installation position, enabling smooth cable wiring and preventing interference with the oil filler cap 54. , the workability of oil injection does not deteriorate.

In the above embodiment, the bracket 16 is the body 1.
Although the embodiment shown in which the bracket 16 is attached to the engine 4 is shown, the bracket 16 can also be attached to the engines 10 and 50. Further, in the above embodiment, the accelerator cable 24 is connected between the pulley 20 and the fuel injection device 32 or the carburetor.
Although an embodiment to which the present invention is applied has been shown, the present invention can also be attached to the connecting portion between the pulley 20 and the accelerator cable 48, the connecting portion between the pulley 20 and the driving accelerator cable of an auto drive device (not shown), etc. Yes, and can be applied to all attachment points between the accelerator control cable and pulley.

As explained above, the present invention has the effect of enabling smooth cable wiring even for engines with completely different accelerator cable wiring using the same accelerator control cable bracket.
