Description

【考案の詳細な説明】 本考案は、自動車のエンジン取付構造に関する。[Detailed explanation of the idea] The present invention relates to an engine mounting structure for an automobile.

従来、第６図に示すように、エンジン２を緩衝具１６上

めに、緩衝具１６に剪断力が頻繁に作用して、緩衝具１
６が疲労破損しやすくなっていた。Conventionally, as shown in FIG. 6, the engine 2 was placed horizontally on a shock absorber 16, so the engine 2 was easily moved horizontally due to its vibrations and vehicle body inclination. A shearing force frequently acts on the shock absorber 1
6 was prone to fatigue damage.

本考案は、かかる実情に鑑みて、緩衝具の疲労破損を抑
制できるようにすることを目的とする。In view of these circumstances, the present invention aims to suppress fatigue damage of shock absorbers.

以下本考案の実施例を例示図に基いて詳述する。Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

能に、かつ分解自在に連結しである。The control unit 1 is located above the engine 2, and the engine 2 output is configured to be transmitted to the front axle via a clutch 3, a gear transmission 4, a transmission shaft, and a differential gear mechanism 5, and an idling wheel is provided at the rear. In a cab-over type transport vehicle equipped with an engine base 2a, four tongue pieces 8 are formed projecting outward from the engine base 2a, and each tongue piece 8 has a hanging connector. The rod-shaped body 9 is connected so that it cannot be pulled out downward and can be disassembled.

ト６．６を取外すことにより、分解できるように取付け
である。A hemispherical rigid body seat 10 inserted into the rod-shaped body 9 is inserted into the washer 11.
It is mounted so that it can be disassembled by removing the upward retaining bolt 6.6 by means of a support member 12, which is a pull-out prevention device, and which passes through the rod-like body 9.

である。A horizontal frame 14.14 is installed on the other pair of left and right vehicle body frames 13.13, and an auxiliary frame 15 is provided across these horizontal frames 14.14, and the upper surface of one of the vehicle body frames 13 and 15 is recessed. Four shock absorbers 16 made of rubber formed into hemispherical surfaces of the shape are arranged so that vertical through holes 17 formed in each frame 13.15 and holes 18 formed in the shock absorbers 16 are aligned. It is also attached.

々揺動自在に取付けである。With the rod-shaped body 9 from which the catch 10 has been removed loosely inserted into the hole 18 of the shock absorber 16, the catch 10 connected to the engine side is engaged with the shock absorber 16 on the frame side, The engine 2 is attached to the frame 13.15 by the hanging rod 9.
The shock absorber 16 and the frame 13, 15 are respectively attached so as to be swingable.

エンジン２巾よりも前記両フレーム１３，１５の間隔を
広くしてあって、棒状体９がら支持部材１２を抜き出す
ことにより、エンジン２を両フレーム１３．１５の間か
ら下方に抜き出すことができるようにしである。The space between the frames 13 and 15 is made wider than the width of the engine 2, so that by extracting the support member 12 from the rod-shaped body 9, the engine 2 can be extracted downward from between the frames 13 and 15. It's Nishide.

このようにエンジン２を取外すのに、棒状体９の下端に

状体９をフレーム１３．１５側に残した１１エンジン２
を下方に抜出すべく構成するもよい。In order to remove the engine 2 in this manner, the support member 12' is pulled out in a direction perpendicular to the rod 9 at the lower end of the rod 9, the washer 11' is pulled out from the lower end of the rod 9, and the rod 9 is assembled into the frame. 13.11 engine 2 left on the 15 side
It may also be configured so that it can be pulled out downward.

尚、エンジン２をフレーム１３．１５に吊下げ状態で取

ン２の取付は箇所を機枠という。Although the engine 2 is attached to the frame 13, 15 in a suspended state, it may be attached to other fixed parts, and the place where the engine 2 is attached is referred to as the machine frame.

又、受座１０の表面に、減摩面を形成して、受座１０と
緩衝具１６との摩擦抵抗を軽減して、緩衝具１６が摩擦
により損傷されるのを抑制するとよい。Further, it is preferable to form an anti-friction surface on the surface of the seat 10 to reduce the frictional resistance between the seat 10 and the shock absorber 16, thereby suppressing damage to the shock absorber 16 due to friction.

又、エンジン２を機枠に吊下げ保持するための、緩衝具
１６とエンジン２とにわたる連結具９の形状形態は種々
変更可能である。Furthermore, the shape and form of the connector 9 that extends between the shock absorber 16 and the engine 2 for suspending and holding the engine 2 on the machine frame can be changed in various ways.

ある事を特徴とする。In summary, the present invention provides a vertical through hole in the machine frame, inserts a rod-like body whose lower end is connected to the engine base, and forms the through hole on the upper side of the machine frame. A shock absorber having a recessed hemispherical upper surface and a hole for inserting the rod-shaped body in the center is attached to the part, and 1. A hemispherical rigid seat corresponding to the recessed hemispherical surface is connected above the shock absorber and to the rod-shaped body portion to suspend and support the engine. Features.

として、緩衝具の耐久性を大巾に向上し得るに至った。The engine is suspended from the machine frame via a hemispherical catch and a shock absorber that corresponds to the hemispherical catch, so that even if the vehicle body is tilted, the engine will not move. The weight can be received by compressive deformation of the shock absorber, suppressing fatigue damage of the shock absorber which is generally prone to shear failure, and overall the durability of the shock absorber can be greatly improved.
