Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement in a pedal support structure in a cab-over type vehicle.

[Prior Art] Conventionally, in a cab-over type vehicle, a pedal bracket is fixed to a dashboard of a vehicle body, the upper end of the pedal is rotatably supported on the bracket, and the pedal is mounted on the lower part of the pivot part. There was a configuration in which a master cylinder that penetrates the dashboard and projects forward is connected, and further a front panel is arranged in front of the master cylinder.

[Problems to be Solved by the Invention] By the way, since the front end of the master cylinder is opposed to the front panel of the vehicle body, a large load is applied to the front panel due to a collision or the like, and the front panel is deformed rearward. When the load abuts on the front end of the master cylinder and the load is larger than a predetermined value, the master cylinder is pushed rearward. As a result, there is a possibility that the pedal may move rearward, and in particular, the tread surface at the lower end of the pedal may jump up toward the driver's foot.

In view of the above-mentioned problems, the present invention has proposed a pedal pedal that prevents the tread surface at the lower end of the pedal from jumping up to the driver's foot even if the pedal moves rearward due to the deformation of the front panel at the front of the driver's seat by improving the pedal bracket. An object is to provide a support structure.

[Means for Solving Problems] A pedal support structure in a cab-over type vehicle according to the present invention has a pedal bracket fixed to a dashboard of a vehicle body, and an upper end of the pedal is pivotally supported on the bracket. In the cab-over type vehicle in which the pedal is connected to a lower portion of a pivot portion of the pedal, a master cylinder that protrudes forward through the dashboard, and a front panel is disposed in front of the pedal cylinder, The pedal is surrounded under the connection between the pedal and the master cylinder to form an enclosure with a substantially U-shaped cross section that regulates the rearward movement of the pedal, and the rear end of this enclosure is used as a steering column located on the side of the pedal. Connected and fixed.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a hydraulic pressure conversion device 3 is arranged between the front panel 1 and the dashboard 5. The hydraulic pressure conversion device 3 includes a master cylinder 31 arranged in the front-rear direction of the vehicle.
And a booster 3 connected to the rear of the master cylinder 31.
2 from the booster 32 to push rod 33
Extends backwards and its tip is a clevis 34,
An intermediate portion of a pedal arm 41 having a tread surface 42 at its lower end is connected to this by pin connection. The hydraulic pressure conversion device 3
Is fixed to the front surface of the dashboard 5 together with a pedal bracket 6 described later. The pedal 4 is rotatably supported by the pivotal support portion 69 of the pedal bracket 6 with the upper end of the pedal arm 41 as the center of rotation A.

As shown in FIG. 3, the pedal bracket 6 is formed by pressing a pair of side walls 61 and 62 from both left and right ends of the top plate 63 and press-forming them into a substantially gate shape with the lower end open. Surrounds the pedal arm 41 below the connecting portion between the pedal arm 41 and the push rod 33, and
An enclosing portion C having a substantially U-shaped cross section for restricting the rearward movement of 1 is formed. Further, the rear end 64 of the surrounding portion C is connected and fixed to the steering column 2 located on the side of the pedal arm 41 through the column bracket 21 so that the rigidity of the entire pedal bracket 6 is effectively increased. There is.

In the figure, reference numeral 66 denotes a front end support portion of the pedal bracket 6, which is formed by bending the front ends of the side walls 61 and 62 outward in a substantially L shape, and 67 denotes the pedal bracket 6 of the hydraulic pressure conversion device. 3 is a coupling hole to be fastened to the front surface of the dashboard 5 together with 3. A buckling deforming portion 68 is provided in a portion of the side walls 61 and 62 forming the surrounding portion C. The buckling deformation portion 68
Can be formed by the hole shown in FIG. 3 or a bellows. Reference numeral 7 denotes a pedal bracket base provided to reinforce the mounting portion of the hydraulic pressure conversion device 3 of the dashboard 5.

With the above configuration, when a large load is applied to the front of the front panel 1, the front panel 1 is deformed to the position indicated by the line D in FIG. 1, and this deformation causes the front panel 1 to contact the front end of the master cylinder 31. The pedal bracket 6 is pushed rearward, and the pedal bracket 6 is compressed and deformed by the buckling deforming portion 68 to absorb energy, and at the same time, the pedal 4 is also pushed by the push rod 33 and similarly moves rearward. However, the pedal 4 that has moved to the rear is
When the intermediate portion of the pedal 4 comes into contact with the rear end 64 of the surrounding portion of the pedal bracket 6 connected and fixed to the steering column bracket 21, the pedal 4 is prevented from moving further rearward, as shown by the chain double-dashed line in FIG. The pedal arm 4
It is possible to solve the conventional problem that the lower end of 1 escapes toward the front of the vehicle and the tread surface 42 of the pedal jumps up toward the driver's foot.

Since the pedal arm 41 is surrounded by the surrounding portion C of the pedal bracket 6, the backward movement of the pedal arm 41 is prevented even if the load from the front of the vehicle is not parallel to the traveling direction of the vehicle and acts slightly obliquely. It can be reliably blocked.

[Advantage of the Invention] With the pedal support structure in the cab-over type vehicle of the present invention, due to the above-described configuration, a large load acts on the front panel of the vehicle due to a collision or the like, and this deforms rearward and abuts on the front end of the master cylinder. Even if the pedal is pushed backwards, the middle part of the pedal contacts the surrounding part of the pedal bracket, and the surrounding part is connected and fixed to the steering column whose rear end is rigid. Movement is reliably blocked. Therefore, there is an effect that the tread surface at the lower end of the pedal can be released to the front without jumping up greatly as in the conventional case.
