Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step-on type air brake device mounting structure for a large vehicle or the like.

[0002]

2. Description of the Related Art Japanese Utility Model Laid-Open No. 6-49252 discloses an air brake device in which a brake pedal and a brake valve are integrated. This type of air brake device includes a step-on brake pedal, and the brake valve is arranged under the floor of a floor panel directly below the pedal.

For large vehicles generally designed and manufactured in Japan, after designing a right-hand drive vehicle for the Japanese domestic market, a left-hand drive vehicle for export is designed on the basis of the right-hand drive vehicle. Has been made in common, and the air brake device including the brake pedal, the brake valve and the like is no exception. For example, when an air brake device having a brake pedal and a brake valve as shown in Japanese Utility Model Laid-Open No. 6-49252 is set in a right-hand drive vehicle, the device may be applied to a left-hand drive vehicle as it is. Occasionally, this interferes with various auxiliaries in the cab frame of the vehicle or the engine room, and this layout may not be established.
In such a case, it is unavoidable to separate the brake pedal from the brake valve and reconnect them with a rod.

FIG. 5 is a side view showing a mounting structure of a conventional step-on type air brake device in which a brake pedal and a brake valve are connected by the rod as described above, and FIG. 6 is a perspective view showing the mounting structure on the pedal side. FIG. 7 is a perspective view showing a mounting structure on the brake valve side, in which a floor panel 1 constituting a cab of a vehicle is provided with an opening 20, and a panel-shaped bracket 22 is fixed to the opening by a bolt 10. It This bracket 22 is connected to the pedal 2 via the pin 2a.
Is swingably supported in the direction of arrow F.

As is apparent from FIG. 5, the brake pedal 2 is connected to the push rod 4 via the pin 2b,
The push rod 4 is a plunger 4d of the brake valve 3.
Press to adjust the valve opening. The brake valve 3 arranged under the floor of the floor panel 1 is fixed by attaching a flange 8 of the bracket 9 to a bracket 9 welded to the lower surface of the floor panel 1 in advance with bolts or the like. In the work of connecting the brake pedal 2 and the brake valve 3 as described above, under the floor of the floor panel 1,
The operator attaches the cover 5 with boots to the opening 20 of the floor panel 1 while looking upward, and connects the push rod 4c on the pedal 2 side and the plunger 4d on the brake valve 3 side by using the joint 4a and the lock nut 4b. It will be.

[0006]

As described above, the work of connecting the push rod 4c and the plunger 4d is under the floor of the narrow floor panel 1, and the worker must work while looking up at the upper part, which is a very difficult work posture. It was strict. In addition, at the time of connecting the both, the nut-shaped joint 4a is rotated with respect to the screw portion 4e formed on the push rod 4c and the screw portion 4f formed on the plunger 4d, and the length between the brake pedal and the brake valve is increased. However, it had to be adjusted accurately, and it was a difficult task in a difficult work posture. The present invention aims to provide an air brake device mounting structure capable of solving these problems.

[0007]

According to the structure for mounting a step-on air brake for an automobile of the present invention, an opening is provided in advance in a floor panel of a cab of a vehicle, and a brake pedal is previously provided in a plate having a shape corresponding to the opening. Install a brake valve, and adjust the length of the push rod that connects this brake pedal and brake valve to form a unit. Then, this unit is attached so as to close the opening of the floor panel of the cab of the vehicle, and the installation structure of the step-on air brake is completed. The brake pedal and the brake valve are attached to the front and back sides of the plate, and the work of adjusting the length of the push rod that connects them is required.
By uniting these, the assembly and adjustment work is simplified.

1 is a side view showing the structure of the device of the present invention, FIG. 2 is an explanatory view showing the work of assembling a brake pedal, FIG. 3 is an explanatory view showing the work of assembling a brake valve, and FIG. 4 is a brake. It is explanatory drawing which shows the operation | work which attaches the unit of a pedal to a floor panel. In the device of the present invention, as shown in FIG. 3, the opening 11 is formed on the floor panel 1.
To form a unit, the brake pedal 2 and the brake valve 3 are assembled in advance to the plate 6 that covers the opening, and the unit is configured, and the unit is fixed to the opening 11 via the seal member 7 by the bolt 10. Is.

In FIG. 2, a panel-shaped bracket 22 for supporting the brake pedal 2 from the front side of the plate 6 is attached to the bolt 10 with respect to the opening 20 formed in the plate 6.
Is fixed. The push rod 4c rotatably supported with respect to the brake pedal 2 projects from the opening 20 to the back side of the plate 6.

FIG. 3 shows a process of assembling the brake valve 3 on the back side of the plate 6. First, the plate 6 is turned upside down, and a rubber / synthetic resin cover 5 for covering the push rod 4c is attached thereto. Next, the flange 8 is attached to the bracket 9 previously welded to the back surface of the plate 6.
The brake valve 3 is fixed via the. The push rod 4c of the brake pedal 2 is provided with a threaded portion 4e, and the plunger 4d of the brake valve 3 is also provided with a threaded portion 4f. Therefore, a nut-shaped joint 4a is screwed onto these threaded portions, and the lock nut 4b is used to adjust the distance between the push rod 4c and the plunger 4d.

As described above, the plate 6 of the unit 30 constructed by assembling the brake pedal 2 and the brake valve 3 to the plate 6 is turned over again, and the opening portion of the floor panel 1 is opened by the bolt 10 as shown in FIG. By assembling and fixing to 11, the step-on air brake device is completed. At this time, the seal member 7 is inserted into the joint between the plate 6 and the floor panel 1 as shown in FIG. 1 to seal the opening.

[0012]

As described above, according to the present invention, the stepping-on pedal and the brake valve of the air brake operated by the pedal are assembled in advance on the front and back sides of one panel as a unit, and this unit is used as a floor. Since the structure is fixed to the opening provided in the panel, the problem of work posture in underfloor work can be solved.

Also, with this structure, it becomes easy to attach a joint for connecting the brake pedal and the brake valve, and further, the work of adjusting the connection length between the push rod of the brake pedal and the plunger of the brake valve by this joint. Will be easier. Therefore,
It is possible to reduce the number of steps of assembling the step-on air brake device with respect to the floor of the cab of the vehicle.
