Abstract

PURPOSE:To prevent the vibration and sway of an engine by supporting in vibrationproofing an engine to a main frame on a travel car body via vibrationproof members and providing a sway limiter fixed to the main frame on one end and provided with a shperical stopper on the other end. CONSTITUTION:An engine 1 is supported in vibrationproofing to a travel car body via vibrationproof members 3. In this case, the left and right vibrationproof members 3 in the front are provided directly on a side frame 8. The left and right vibrationproof members 3 in the rear are provided between a curved main frame 2 connecting the side frame 8 and a V type sub-frame 4 fixed to the back lower section of the engine 1 with each center line inclined inwardly. A sway limiter 5 is clamped to the center section of the main frame 2, and it penetrates a mouth section 11 formed on the sub-frame 4. A spherical stopper 6 located above the said mouth section 11 and made of hard rubber, etc. is inserted at the top of the sway limiter 5. On the other hand, a spherical pad 7 is formed around the said mouth section 11.

Description

[Detailed Description of the Invention] This invention relates to an engine support device for agricultural tractors, etc., which supports the engine with good vibration isolation and restricts swinging in the left-right direction or front-rear direction. This is to prevent accidental interference with the cell cover, etc.

For this reason, the present invention has taken the following technical measures. That is,
The engine (1) is anti-vibration supported on the main frame (2) on the traveling aircraft side via anti-vibration members (3) (3)...
A swing regulating body (5) fixed at one end to the main frame (2) to the engine (1 side sub-frame (4) in a substantially vertical position)
An engine for an agricultural tractor or the like in which a spherical stopper (6) is provided at the other end, and this spherical stopper (6) is brought into contact with a spherical catch (7) formed on a sub-frame (4) or a main frame (2). It is configured as a support device.

An embodiment of this invention will be described based on the drawings.

(8) and (3) are the side frames that constitute the traveling aircraft body, which are installed in a horizontal position at appropriate intervals on the left and right, and have eye rings (9).
A front wheel bracket (not shown) that supports the rear wheel (9) and a transmission case (not shown) that transmits power to the rear wheel (10) 001 are rigidly connected.

The Ennon (1) is vibration-proofly supported by the traveling aircraft via vibration-proofing members (3) (3)... Among these, the front left and right vibration-proofing members (3) (3) are provided directly on the side frames (8) (8), and the rear left and right vibration isolating members (3) (3) are curved tops L that span to connect the side frames (8) (8). , .

(5) is a swing regulating body that is fixed to the left and right center of the main frame (2) in a substantially vertical position, and has a large diameter opening (11) formed on the sub frame (4) to pass through. provided.

A spherical strip (6) made of a hard comb or the like is fitted onto the upper part of the swing regulating body (5), located above the opening 0υ. The mouth of the sub-frame (4) (the area around Jυ is formed into a spherical shape to serve as the seat (7), and the spherical mi stopper (6)
) or contact (-7).

040 is a side cover, 0■ is a two-part opening/closing bonnet, and (14) is a run.

In the above configuration, the ennon (1) is the left and right vibration isolating member (3) (3) after f3iJ and the side frame (8) (8
) to main frame (2) K I! 7j vibration is supported, so the vibrations caused by the aircraft running and the vibrations caused by the activation of the engine are absorbed and alleviated by the vibration isolating part A (3) (3)... The vibration isolating member (3) (3) Since the fixed edges on the frame side and the engine side are in a relationship where they are relatively contracted 2 or can be shifted in any lateral direction, the frame (8) (8
) or (2), Ennon (1) tries to swing relatively in the left-right direction or front-back direction due to specific vibration, but the spherical stopper (6) of the swing regulating body (5) is By coming into contact with the seat (7) of the frame (4), it is possible to restrict the rocking in the left-right and front-back directions, and to prevent unexpected interference with the side covers θ to 0, etc.

In addition, regarding the vertical direction of Ennon (1), vibration isolating members (
3) In (3), one force vibration action can be applied to 14 peaks within the range of contact with the spherical stopper (6) or catch seat (7).

This invention has the following technical effects because it has the configuration described in No. 111. That is, the vibration isolating member absorbs and alleviates vibrations caused by aircraft vibration and engine startup, but each fixed edge of the vibration isolating member with respect to the main frame or the sub-frame may shift laterally relative to the IH. Therefore, even if the Ennon tries to swing from side to side or back and forth, the spherical stopper of the swing regulating body comes into contact with the spherical catch and restricts the swing. You can prevent one attack on the Kummers. Further, the vibration isolating member can maintain the foreign language for a long time without fear of excessive deformation.

In this embodiment, the swing regulating body (5) is fixed to the main frame (2) side and a spherical catch (7) is formed on the sub frame (4). The regulating body (5) may be suspended and supported on the sub frame (4) side, and the spherical seat (7) of the collar (6) may be formed on the main frame (2) side.
