Abstract

A hybrid system for a vehicle includes a drive unit provided with a motor for driving wheels and a power generation unit provided with an engine and a generator driven by the engine. The power generation unit is provided so as to be adjacent to the drive unit in a separated state. One of the drive unit and the power generation unit is mounted on a vehicle body via a first mount member at a lower portion of the one unit. The other one of the drive unit and the power generation unit is mounted on the vehicle body via a second mount member at an upper portion of the other one unit.

First claim

The invention claimed is:

1. A hybrid system installed in a vehicle, comprising:
a drive unit comprising a motor for driving wheels; and
a power generation unit comprising an engine and a generator configured to be driven by the engine, wherein the power generation unit is adjacent to the drive unit separated from the drive unit, wherein
one of the drive unit and the power generation unit is mounted on a vehicle body via a first mount member at a lower portion of the one unit such that an upper portion of the one unit is capable of swinging independently from the other one of the drive unit and the power generation unit, and
the other one of the drive unit and the power generation unit is mounted on the vehicle body via a second mount member at an upper portion of the other one unit such that a lower portion of said other one is capable of swinging independently from the one unit.

2. The hybrid system according to claim 1 , further comprising:
an inverter for controlling the motor and the generator, wherein
the inverter is arranged above the one unit fixed by the first mount member.

3. The hybrid system according to claim 2 , wherein
the drive unit is mounted on the vehicle body via the first mount member,
the power generation unit is mounted on the vehicle body via the second mount member, and
the drive unit is arranged behind the power generation unit in a front-rear direction of the vehicle.

4. The hybrid system according to claim 3 , further comprising:
a harness which is a wiring for connecting the generator and the inverter, and is arranged between the drive unit and the power generation unit, wherein
the generator includes a connection portion with the harness on an opposite side of the drive unit.

5. The hybrid system according to claim 4 , wherein
the drive unit includes a first support member for supporting an intermediate portion of the harness at a position closest to the power generation unit.

6. The hybrid system according to claim 5 , wherein
the first support member includes:
a main body portion fixed to the drive unit, and
a holding portion that is attached to the main body portion and holds the harness, and

a holding position of the harness by the holding portion is lower than a position where the main body portion is fixed to the drive unit.

7. The hybrid system according to claim 5 , wherein
the power generation unit includes a second support member for supporting an intermediate portion of the harness below the first support member.

8. The hybrid system according to claim 7 , wherein
when the intermediate portion of the harness supported by the first support member is defined as a first support region, and the intermediate portion of the harness supported by the second support member is defined as a second support region, when viewed from a front-rear direction of the vehicle, the first support region and the second support region are set so as not to deviate in a vehicle width direction of the vehicle.
