JPS5921992Y2 - Component mounting structure on the front of the tractor - Google Patents

Description

[Detailed description of the invention] This invention relates to a component mounting structure on the front of a tractor.
More specifically, structural members such as the bonnet, fuel tank, and rearview mirror can be used for multiple purposes by effectively utilizing the arrangement and rigidity of the tank mounting frame, which has a gate shape as a whole for mounting the fuel tank. It was designed to further simplify the vehicle and make it cost-effective by attaching other components.

As is well known, for example, in agricultural tractors, for reasons such as increasing the size of the fuel tank, the tank mounting support frame is made into a gate shape to strengthen its rigidity, and the flange is also mounted vertically to make the tank itself more effective. In this case, the tank mounting frame is placed between the front and back of the fixed bonnet at the rear and the openable bonnet at the front, and its outer peripheral surface is flush with these bonnets. He is said to be dressed in a fashionable manner.

By the way, agricultural tractors have a rearview mirror attached to the bonnet, etc., and the attachment of the rearview mirror and bonnet has a problem of low strength and vibrations that make it difficult to see from the tractor body.

This invention solved all of these problems, and its characteristics are that the fuel tank is placed behind the engine, and the rear bonnet is placed behind the front bonnet that covers the engine. At the section, a mounting frame having a gate-shaped part exposed from between the front and rear bonnets is erected from the tractor body side, a fuel tank and the front and rear bonnets are fixed to the gate-shaped part of this mounting frame, and this gate is fixed to the gate-shaped part of the mounting frame. The point is that a rearview mirror is attached to the outer periphery of the mold part.

This invention will be explained below with reference to an illustrated example.

What is shown in Figures 1 to 4 is an example of an agricultural tractor. In this type of tractor, 1 is a tank mounting support frame, and this includes a protective frame 2, front and rear bonnets 3 and 4, and a rearview mirror. 5 is also installed.

That is, T is the body of a tractor, and this body T has an engine 7 at the front with a front wheel bearing stand 6 at the front end, a transmission case 8 at the rear, and a flywheel case 9 and a clutch housing in between. 10 are connected and integrated.

The front axle bearing pedestal 6 is a U-shaped long piece fixed to both sides of the engine 7 and is made to project forward. An auxiliary frame 12 that moves forward and backward and is fixed with a lock pin 11 at an appropriate position is inserted and supported, and the front weight 13 shown in the figure can be moved back and forth with its front ends. It will also happen.

The bonnet is composed of a fixed rear bonnet 4 and an openable front bonnet 3 that largely envelops the engine 7, etc. In particular, the front bonnet 3 has an L-shaped fixed bonnet 15 with a front grill 14 attached to the front grille 14. It has a pair of left and right supplementary opening/closing side plates 16 that are fixed to the bearing stand 6 side and fit within the L shape, and between these and the tank mounting support frame 1, there is a main opening/closing side plate 17 on the upper part and a safety side plate on the lower part. A cover 18 is attached.

In this way, an opening/closing cover plate 19 is provided at the top, and the connections between these plates can be freely attached and detached using quick fasteners 20 or bolts 21.

On the other hand, the fuel tank 22 on the back of the engine 7 is connected via the upper half of the tank mounting support frame 1, which is integrally formed into a gate shape with a pair of left and right vertical rods 23, 23 and a horizontal rod 24 installed between the upper ends thereof. The flange 25 of the tank is installed in such a way that it is oriented vertically.

In this case, the tank mounting support frame 1 is the bracket on both legs at the lower end)
26, 26 were bolted to both sides of the fuselage T and erected, so that the outer circumferential wall was interposed between the front and rear bonnets 3 and 4 so that they were flush with each other, and the wall surface was exposed to the outside. It's looking good.

A plurality of mounting tongues 27 are protruded from the front and rear of the support frame 1, and the ends of the front and rear bonnets 3, 4 are removably fixed via these tongues 27. , and further equipped with rearview mirrors 5, 5 via this support frame 1,
The front end support of the protective frame 2 is also fixed via both shoulder portions of the support frame 1.

In addition, 28 is a hanging metal fitting protruding from the top of the tank mounting support frame 1.

According to the invention described in detail above, the front and rear bonnets 3, 4 are arranged at the front of the tractor in which the fuel tank 22 is arranged behind the engine 7 and the rear bonnet 4 is arranged behind the front bonnet 3 that covers the engine 7. A mounting frame 1 having a gate-shaped part exposed from between is erected from the tractor body side, and a fuel tank 22 and front and rear bonnets 3, 4 are fixed to the gate-shaped part of this mounting frame 1. Since the rearview mirror 5 is attached to the outer periphery of the molded part, the fuel tank 22 and the front and rear bonnets 3 are attached to the strong mounting frame 1 with the gate-shaped part.
, 4 can be installed at the same time, and since the three components reinforce each other, the installation strength is increased, and there is no need for a mounting bracket for each component, so the structure is simplified and installation is easy. In addition, since the rearview mirror 5 is attached to the mounting frame 1, the rearview mirror is attached with high strength and does not vibrate relative to the tractor body, making it easy to see. It is easy because it can be done at the same time as the component parts.
