Description

The present invention relates to power line support structures.

Conventionally, when installing the power line consisting of the engine and transmission on the vehicle body side, it is mounted on the vehicle body side via an engine mount equipped with a mounting rubber, which transmits engine vibrations to the vehicle body. This reduces the displacement of the engine due to torque reaction force, input from the road surface, etc., and supports the weight of the power line.

For example, in a small truck, the power line is suspended between the left and right side rails on the production line by a hoist or the like, and both sides of the engine are assembled to the left and right side rails via engine mounts, while the engine is connected to the rear part of the engine. The transmission is hidden under the cross member and assembled to the cross member via the engine mount.

Prior art document information related to this type of power line support structure includes the following patent document 1 and the like.
