Description

[Detailed description of the invention] [Industrial application field] The present invention consists of a main frame that is integrally connected to the loading platform, and a traveling machine platform frame that is integrally connected to the driving rear wheels. The present invention also relates to a transport vehicle in which the main frame is mounted on the traveling machine frame, and the main frame and the traveling machine frame are connected via a cushioning material.

[Conventional technology]

A structure in which the main frame and the traveling machine base frame are constructed separately as described above is advantageous in that it can improve efficiency in the manufacturing process and assembly process, but in conventional transport vehicles of this type, As shown in Figure 6, a towing hook was attached to the rear end of the main frame to enable the towing of a trailer, etc., so when towing, the connection between the traveling machine frame and the main frame The interposed cushioning material was sometimes damaged.

[Problem that the invention attempts to solve]

The above-mentioned cushioning material is essential for alleviating vibrations from the rear drive wheels and transmitting them to the main frame. However, when towing a trailer, etc., it is necessary to combine the large towing load with the load on the main frame. Since the resultant force acts intensively on the cushioning material, there is a risk that the cushioning material will be strongly crushed and damaged.

The purpose of the present invention is to provide a transport vehicle that has a simple structure by simply changing the way the towing hook is attached, and that makes it easy to avoid damage to the cushioning material and that can easily exert good traction force.

[Means for solving problems]

The technical means of the present invention taken to solve the above-mentioned problems is to configure the main frame, which is integrally connected to the loading platform, and the traveling machine platform frame, which is integrally connected to the driving rear wheels, as separate bodies. In addition, the main frame is mounted on the traveling machine base frame, and the main frame and the traveling machine base frame are connected via a cushioning material, and the towing hook is mounted on the traveling machine base frame. The feature is that it is integrally provided on the traveling machine frame side.

[Effect]

As a result of taking the above technical means, the following effects (i) and (ii) can be obtained.

(i) The traction load acts directly on the traveling machine frame without going through the main frame or cushioning material, and only the load on the main frame acts on the cushioning material.

(ii) Since the traction hook, which is the point of application of the traction load, is attached to the traveling machine frame which is lower relative to the ground than the main frame, the traction load is applied from the grounding point of the rear drive wheel. The height to the point of application can be set relatively low, and therefore, compared to the case where the point of application of the traction load is set at a high position such as the main frame portion, it is easier to make the wheel drive force act effectively as a traction force.

[Effect of idea]

Due to the above-mentioned effects, it was possible to obtain a transport vehicle having a structure in which damage to the cushioning material can be easily avoided and traction force can be easily exerted.
