Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a vehicle body structure of a cab-over type vehicle, and more particularly to a vehicle body structure around a step portion for getting on and off.

<Prior Art> In a vehicle such as a large truck having a high cab floor surface, a step for getting on and off is generally provided in consideration of getting on and off. Then, the fender portion is extended to the lower end of the step so that the step and its surroundings are not contaminated by mud splashing up from the tire and surrounds the step surroundings.

<Problems to be solved by the invention> By the way, in a cab-over type vehicle that tilts the cab, if a step for getting on and off is provided on the cab side,
As shown in FIG. 5, it is necessary to prevent the lower end of the fender portion 1 from interfering with the tire 2 when the cab is tilted around the tilt center 4, and the range in which the step 3 can be extended backward is restricted. It is ahead of point A. For this reason, the length of the step 3 in the front-rear direction is shortened, and the getting on / off property is poor. On the other hand, if step 3 is attached to the vehicle side such as a frame and the lower end of the fender portion 1 is cut as shown by the broken line in the figure as shown in FIG. The length in the front-rear direction can be increased, and the getting on / off property can be improved. However, in this case, a gap is created between the step 3 and the lower end of the fender portion 1, and the upper surface of the step 3 and its surroundings are soiled by the mud splashed up from the tire 2. In the figure, 5 indicates a front axle center, respectively.

Incidentally, as a technology for preventing the interference between the step and the tire in the cab-over type vehicle, there is one disclosed in, for example, Japanese Utility Model Laid-Open No. 55-56741.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a body structure of a cab-over type vehicle that can prevent dirt on the step and its surroundings while ensuring the stepping on and off properties of the step.

<Means for Solving the Problems> Therefore, in the present invention, in the cab-over type vehicle in which the cab is tilted, the step for getting on and off is fixed to the body frame side, and the fender portion surrounding the step except the step on the getting on and off side of the step. The lower portion is formed of a flexible member having an elastic restoring force, and the lower end portion of the step rear end side is formed in a curved shape.

<Operation> According to this configuration, when the cab is tilted, the lower end of the step rear end side of the fender is deformed in the interference range with the tire, and the external force due to the interference is absorbed to exert an unreasonable force on the fender and the step. When it passes through the interference range, it elastically returns to its original shape. This allows
Since it is not necessary to cut the lower end of the fender portion even if the length of the step in the front-rear direction is lengthened, it is possible to ensure the entry / exitability, and also to prevent the step upper surface and its surroundings from being soiled.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 showing an embodiment of the present invention, a fender portion 12 provided on the cab 11 side is composed of a sheet metal fender body 13 and a splash rubber 14 attached to a lower end of the fender body 13. The splash rubber 14 is divided into upper and lower parts, the upper splash rubber 14A is made of a relatively hard material, and the lower splash rubber 14B is made of a flexible rubber having an elastic restoring force as a flexible member. ing.

The boarding / alighting step 15 is made of, for example, aluminum and is fixed to the body frame side (not shown).

Then, the step periphery except the boarding / alighting side of the step 15 is surrounded by the lower splash rubber 14B of the splash rubber 14, and the lower end portion 16 of the lower splash rubber 14B on the rear end side of the step 15 is chamfered to form a curved surface. I am doing it. 17 is a tire.

With such a configuration, when the cab 11 is tilted up, the lower splash rubber 14 of the splash rubber 14 is
When B hits the tire 17, it is deformed as shown by the solid line in FIG. In this state, the cab 11 ascends as it is, and when it goes beyond the interference range between the lower splash rubber 14B and the tire 17, the lower splash rubber 14B elastically returns to its original shape as shown by the broken line in FIG. Similarly, when the cab 11 is tilted down and reaches the interference range with the tire 17, the lower splash rubber 14B is deformed, and when the cab 11 passes through the interference range, the lower splash rubber 14B elastically returns to its original shape. Since the lower end 16 of the lower splash rubber 14B that hits the tire 17 is formed in a curved surface, the sliding contact operation with the tire 17 is performed relatively smoothly, and an unreasonable force is applied to the lower end of the lower splash rubber 14B. There is no risk of damage even if you do not add to 16.

For this reason, it is possible to increase the length of the step 15 in the front-rear direction without cutting the lower end portion of the fender portion 12, which facilitates getting on and off and does not require a gap between the step 15 and the fender portion 12. , Step 15 The top surface and its surroundings are less contaminated. In addition, since the back and front and rear wall portions of step 15 are made of soft rubber, they are less likely to be scratched even when hit by the toes, as compared with the case of a conventional sheet metal or hard resin.

<Effect of the Invention> As described above, according to the present invention, it is not necessary to cut the lower end of the fender even if the length of the step for getting on and off is increased in the front-rear direction. Moreover, dirt around the step can be suppressed. Also,
Even if the toes of people getting on and off hit the lower end of the fender, they are less likely to get scratched and have a protective effect on the appearance.
