Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a pedal bracket for pivotally supporting a clutch pedal with a clutch interlock mechanism.

(Prior Art) An example of a conventional pedal bracket with a clutch interlock mechanism is shown in FIG. 3 (GENE 1984
LIGHT DUTY TRUCK S SERIE issued by RAL MOTOR CORPRATION
S SHOP MANUAL page 7C-7, see 7C-8).

In the figure, 1 is a vehicle upper dashboard, 2 is a lower dashboard, 3 is a floor board, 4 is a pedal bracket fixed to the upper dashboard 1 by bolts 5 and nuts 6, 7 is a clutch pedal, and 8 is a clutch pedal 7. A shaft pivotally supporting the base on the pedal bracket 4, 9
Is a switch bracket which is welded to the lower edge of the pedal bracket 4 and protrudes downward, 10 is an interlock switch attached to the lower end of the switch bracket 9,
Reference numeral 11 denotes a switch operating bracket projecting from the clutch pedal 7 so as to face the contactor 10a of the interlock switch 10. Reference numeral 12 denotes a stopper that restricts the stroke of the clutch pedal 7, and a lower dashboard 2 by a bolt 5 and a nut 6. Has been concluded.

Then, depress the clutch pedal 7 to
Abut the stopper 12 and press the interlock switch.
If the starter switch for starting the engine is operated while 10 is turned on, the starter motor can be operated and the vehicle can be prevented from jumping out when the engine is started.

(Problems to be solved by the invention) However, in the conventional pedal bracket with the clutch interlock mechanism as described above, the stopper 12 for restricting the stroke of the clutch pedal 7 is provided on the lower dashboard 2 with the bolt 5 and the nut. Since it is fastened with No. 6, it is necessary to push the clutch pedal 7 by hand until it hits the stopper 12 in the assembly line, and in that state, the interlock switch 10 is turned on.
Since the mounting position must be adjusted in order to operate, there is a lot of work in the assembly line, and since it is a narrow space below the instrument panel, the adjustment work is difficult and unreliable. There was a problem.

(Means for Solving Problems) In order to solve the above problems, in the present invention, an interlock switch is fixedly attached to a pedal bracket that pivotally supports a clutch pedal, and separately from this interlock switch. A pedal bracket with a clutch interlock mechanism is constructed by integrally fixing a stopper bracket for restricting the stroke of the clutch pedal in the vicinity of the mounting base of the pedal bracket.

(Operation) As described above, in the present invention, both the switch bracket for mounting the interlock switch and the stopper bracket for restricting the stroke of the clutch pedal are
Since it is fixed to the pedal bracket, it can be supplied to the assembly line as a pedal bracket assembly including a switch bracket and a stopper bracket. Therefore, the position adjustment work of the interlock switch is easily and quickly performed before the assembly line, and the reliability thereof is also improved. Furthermore, the work on the assembly line is as easy as a vehicle without an interlock mechanism.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS.
In the figure, the same reference numerals as those used in the previous description denote the same elements.

In this embodiment, a switch bracket 9 for attaching an interlock switch 10 is fixed by welding to a lower edge portion of a pedal bracket 4 that pivotally supports the clutch pedal 7 via a shaft 8 and the stroke of the clutch pedal 7 is restricted. Similarly, the stopper bracket 13 is fixed to the lower edge portion of the pedal bracket 4 by welding.

The clutch pedal 7 has an engaging claw portion 8a on the upper portion of the shaft 8,
The other end of the clutch cable 21 whose other end is connected to a clutch device (not shown) is connected to the clutch pedal 7.
When depressing, the other end of the cable 21 is pulled to actuate the clutch device in the disengaged state as shown by the chain line.

The clutch pedal 7 includes a switch operating bracket 11, a return position regulating stopper 22 that is biased to the return side by the operation of the pedal return spring 27 and serves as a pedal return side stopper, and is fixed to the pedal bracket 4 by welding or the like. The pedal return detection switches 24 and 25 are turned on when the pedals are returned, by facing the return stopper bracket 23.

26 is the stopper bracket 13 at the pedal depressed position
Is a stopper that abuts against, and is similarly fixed to the clutch pedal by welding or the like.

The interlock switch 10 will be described in detail with reference to FIG. 2. The switch body 10b is screwed into the weld nut 9a provided on the switch bracket 9 to lock the lock nut 10c.
To prevent loosening.

Reference numeral 10a denotes a contact of the interlock switch 10, which is operated from off to on when the switch operation bracket 11 comes into contact, and its position can be changed by changing the screwing position with respect to the weld nut 9a. The mounting position is adjusted so that the interlock switch 10 is turned on at the same time when the stopper 26 contacts the stopper bracket 13.

Next, the operation will be described.

First, the operation will be described. When the clutch pedal 7 is depressed, the clutch pedal 7 bends the pedal return spring 27 around the shaft 8 and the clutch cable.
21 is pulled to put the clutch device in the power transmission released state.

At this time, the clutch pedal 7 is rotated from the state shown in the figure to the state shown in the chain double-dashed line, and the stopper 26 moves the stopper bracket 13
When the switch operating bracket 11 contacts the contact 10a of the interlock switch 10 at the same time as the switch 1
When 0 is turned on, the engine can be started.

According to the present invention, when assembling the pedal bracket assembly before the assembly line, the clutch pedal 7 attached to the pedal bracket 4 is pressed against the stopper bracket 13 also attached to the pedal bracket 4, and then attached to the switch bracket 9 in that state. The interlock switch 10 is adjusted so that the contact 10a of the interlock switch 10 comes into contact with the switch operating bracket 11 projecting from the clutch pedal 7 and operates properly. Therefore, in the assembly line, it is sufficient to fasten the pedal bracket 4 to the upper dashboard 1 with the bolt 5 and the nut 6.

In the above embodiment, the switch bracket 9 is provided separately from the stopper bracket 13, but the switch bracket 9 and the switch actuation bracket 11 are eliminated, and instead, the stopper bracket 13 and the interlock switch 10 are replaced.
May be provided and operated by the clutch pedal.

(Effect of the Invention) As described above, according to the present invention, the stopper bracket 13 that restricts the stroke of the clutch pedal 7 is used.
Since it is also fixed to the pedal bracket 4, the adjustment work of the interlock switch 10 can be done in a short time in the pedal bracket assembly state and the reliability is improved, and the work on the assembly line is the same as that of the vehicle without the clutch interlock mechanism. It has the excellent effect of being significantly easier.
