Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching bonnet side plates of a vehicle such as a tractor, and the present invention relates to a structure for attaching a bonnet side plate of a vehicle such as a tractor. The purpose is to prevent wobbling in both directions and inward and outward directions.

In an agricultural tractor, an engine room in which an engine, a radiator, a battery, etc. are arranged is covered by a bonnet, and the bonnet has a top plate, a pair of left and right side plates, and a front grill. Then, a front axle frame is protruded forward from the engine to form the front part of the tractor body, a frame is provided on this body, a top plate is fixed to the top of this frame, and the front of the frame and the body is fixed. A front grill is attached to the front panel, and left and right side panels covering the sides of the engine room are removably attached between the top plate and the fuselage.

In the conventional side plate, the upper edge is locked to the top plate, and the lower part is detachably attached to the fuselage via an engagement tool. This engagement tool is provided only at one location in the center in the longitudinal direction, and must be manually engaged and removed when attaching and detaching the side plate, so it is difficult to provide it at two locations. If the airframe is not fixed in place, vibrations from the aircraft body may cause rattling in the longitudinal and inward and outward directions, causing noise.

The present invention solves these conventional problems and is characterized by the fact that the side plate 12 of the bonnet 7 that covers the engine compartment of the vehicle is
The upper edge 12a is locked to the side edge of the top plate 11 from above, and a hook member 31 that is rotatable around a horizontal axis is provided at the lower part of the side plate 12 in the middle part in the front-rear direction, and the hook member 31 and the hook member 31 are connected to the vehicle body 9. In the bonnet side plate mounting structure in which an engaging member 35 is provided for regulating the internal and external movement and upward movement of the side plate 12, the lower part of the side plate 12 and the fuselage 9, which are spaced apart from the hook member 31 in the front and back direction, include: A protrusion member 38 having an enlarged tip is fixed to one side, and the other side is fitted to the protrusion member 38 from the side in a pinching manner to form a side plate 12.
The point is that an engaging body 40 made of a spring plate is fixed, which restricts movement in the medial-lateral direction and the front-back direction.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows the entire agricultural tractor 1.

The front axle frame 10 indicates a muffler that extends upward from the engine through the bonnet 7, and the bonnet 7 has a top plate 11, left and right side plates 12, a front grill 13 in front of them, and It has a rear bonnet 14 at the rear.

In FIG. 2.3, the top plate 11 has mounting parts 17 formed at four corners, and a bracket bolted to a frame 19 (only the front side is shown) that is erected on the mounting parts 18 of the front axle frame 8. 20 via bolts, a recess 21 for protruding the muffler 10 is formed on one side edge, and a locking portion 23 having an upwardly open groove 22 is formed on both side edges. ing.

The downwardly bent upper edges 12a of the left and right side plates 12 are attached to the both side locking portions 23 of the top plate 11.
It can be locked from above via. This side plate 12
Although the left side plate 12 has a substantially symmetrical shape, a recessed portion 25 is formed in the left side plate 12 so as to face the recessed portion 21 of the top plate 11.

The side plate 12 is made of pressed sheet metal, and a side belt 26 is bolted to the midway point in the vertical direction for reinforcement and to improve the design, and a safety cover 28 made of punched metal or wire mesh is provided in the opening 27. ing.

Furthermore, a hook member 31 of the engagement tool 30 is provided at the lower part of the side plate 12 in the middle in the front-rear direction. The engaging tool 30 is constructed by penetrating the shaft 33 of the handle 32 from the outside of the side plate 12, providing a hook member 31 on this shaft 33, and attaching the engaging member 35 to the front axle frame 8 via a bracket 34. By rotating and detachably engaging the hook member 31 with the headed pin-shaped engaging member 35, the side plate 12
The lower part is restricted from moving laterally to the left or right and upward relative to the fuselage 9.

A restrictor 37 is provided between the lower front end of the side plate 12 and the frame 19. This restrictor 37 has a protruding member 38 fixed to the inner surface of the side plate 12 and has a large diameter tip.
