Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a wheel apron provided as a mud scattering prevention wall between a wheel and an engine in a cab-over type truck vehicle.

Generally, in cab-over type trucks, a wheel apron is installed in the form of a bulkhead between the wheels and the engine in order to prevent mud and water from the tires from splashing onto the engine, especially the electrical system part, while the vehicle is running. ing.

Conventionally, this type of wheel apron structure was developed in 1989, when a wheel apron made of iron plate was integrally formed with a damper tower for mounting a suspension damper.
Similar to the seal plate shown in Publication No. 449,
It is designed to hang from the bottom of the cabin floor.

Therefore, the length of the wheel apron has to be long from the bottom of the cabin floor to the vicinity of the chassis frame in order to fulfill the function of preventing mud from scattering, resulting in a problem that the wheel apron is large and heavy.

The present invention has been developed in view of this point, and by attaching the wheel apron to the chassis frame using a damper tower instead of hanging down from the lower surface of the cabin floor, the mud scattering prevention function is impaired. To provide a wheel apron structure for a cab-over type truck vehicle that does not require extending the upper part of the wheel apron to the cabin floor, thereby reducing the size and weight of the vehicle.

That is, in the present invention, in a cab-over type truck vehicle in which the lower part of a damper tower for mounting a damper is fixed to the left and right outer surfaces of a chassis frame extending in the longitudinal direction on the left and right sides of the vehicle body, both ends of the damper tower in the longitudinal direction of the vehicle body are fixed. A front apron is provided with a front apron having a retaining piece at its rear end that engages with the front flange, and a rear apron that has a retaining piece at its front end that engages with the rear flange. , the front apron has its engagement piece engaged with the front flange and its lower part screwed to the chassis frame, and the rear apron has its engagement piece engaged with the rear flange and its lower part fixed to the chassis frame. The front apron is fixed with screws,
The feature is that the wheel apron is composed of a rear apron and a damper tower.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

In Figures 1 and 2, 1 is the cabin floor of a cab-over type truck, 2 is a chassis frame that extends in the longitudinal direction of the left and right sides of the vehicle body below the cabin floor 1, and 3
is a leaf spring, 4 is a cross member, 5 is a wheel,
6 is a damper, and 2a is a mudguard plate mounting bracket.

Reference numeral 7 designates a damper tower for mounting the damper 6, and the lower end portions of the damper tower 7 are fixed to the left and right outer surfaces of the chassis frame 2.
A front flange 8 and a rear flange 9 are integrally formed at both ends in the longitudinal direction of the vehicle body, and 10 and 11 are a front apron and a rear apron respectively arranged on the front and rear sides of the vehicle body of the damper tower 7. Both aprons 10 and 11 are both made of resin, and each has a reinforcing rib 10a on its surface.

11a are formed in a vertical and horizontal grid pattern, and the front apron 10 has a lower end shaped along the chassis frame 2, a rear end shaped like the damper tower 7, and an upper end shaped like the damper tower 7. The rear apron 11 is formed in a shape that follows the front cabin floor 1 at one-letter intervals, and the rear apron 11 has a lower end that follows the chassis frame 2, a front end that follows the damper tower 7, and an upper end that follows the chassis frame 2. are formed along the cabin floor 1 behind the damper tower 7 at regular intervals.

Further, the front apron 10 has two claw-shaped engagement pieces 12 and 12 integrally protruding from the rear end thereof to engage with the front flange 8 of the damper tower 7.
A mounting hole 13 is formed on the front side of the flat end, and the engagement piece 12,
12, it is engaged with the front flange 8 so as to be positioned and fixed in the left-right direction of the vehicle body as shown in FIG. 3, and is fixed to the chassis frame 2 through the mounting hole 13 with screws 14.

On the other hand, the rear apron 11 has two claw-shaped retaining pieces 1 at its front end that engage with the rear flange 9 of the damper tower 7.
5.15 is integrally protruded, and mounting holes 16, 16.16 are bored on the front and rear sides of the flat end and on the upper side of the rear end, and the retaining piece 15.15 is used as shown in FIG. is engaged to position and fix it in the left and right direction of the vehicle body,
At the above mounting hole 16.16°16, attach the chassis frame 2.
and bracket) 2a with screws 17, 17, and 17.

The damper tower 7, front apron 10, and rear apron 11 constitute a wheel apron 18.

Therefore, in the above embodiment, between the wheel 5 and the engine (not shown), the damper tower 7, the front apron 10, and the rear apron 11 continuously form a continuous partition wall to form the wheel apron 18. By doing so, it is possible to reliably prevent mud and water springs generated by the contact between the wheels 5 and the running surface during running from being directly splashed onto the engine, and the wheel apron 18 can be replaced with the existing damper tower 7 only. In addition to using the parts, it is attached to the chassis frame 2 side and the upper part is attached to the cabin floor 1.
Since it does not need to be extended to a certain extent, it can be made smaller and lighter without impairing the above-mentioned scattering prevention function.

Furthermore, since the front apron 10 and rear apron 11 that constitute the wheel apron 18 are made of resin, it is possible to further reduce the weight.

Further, since the wheel apron 18 is provided on the chassis frame 2 side and its upper part does not extend to the cabin floor 1, there is an advantage in a tilting vehicle that it does not interfere with inspection or repair of the engine when tilted up.

As described above, according to the present invention, the front apron and the rear apron are attached to the chassis frame side on both the front and rear sides of the damper tower so as to form a continuous bulkhead with the damper tower, thereby achieving the mud blow-out prevention function. It is possible to reduce the size and weight of the wheel apron without damaging it, and it is possible to contribute to reducing the weight of cab-over type trucks.

In addition, if the front apron and the rear apron are made of resin, there is an advantage that the wheel apron can be made even lighter.
