Abstract

A work machine includes a machine body, an engine, a rotary electrical device, and an electric power controller. The engine is provided on the machine body to move the machine body. The rotary electrical device is provided on the machine body to move the machine body. The electric power controller is disposed above the rotary electrical device in a height direction along a height of the work machine to control the rotary electrical device.

Claims (36)

1. A work machine comprising:

a machine body;

an engine to move the machine body;

a rotary electrical device to rotate around a rotational axis to move the machine body, the rotary electrical device comprising:

a housing coupled to the engine, the housing comprising:

a housing main body;

a first lateral extension integrally extended from the housing main body in a first lateral direction substantially perpendicular to the rotational axis; and

a second lateral extension integrally extended from the housing main body in a second lateral direction opposite to the first lateral direction; and

a connector provided on the housing main body;

an actuator disposed opposite to the engine with respect to the rotary electrical device to be driven by at least the engine;

an electric power controller to control the rotary electrical device;

a cable connecting the electric power controller and the connector of the rotary electrical device;

a particulate removal device to capture particulates in exhaust gas discharged from the engine, the particulate removal device being provided above the rotary electrical device in a height direction along a height of the work machine and between the engine and the cable along the rotational axis;

a first mount device provided on the machine body to support the engine;

a second mount device provided on the machine body and connected to the first lateral extension to support the housing, the second mount device comprising a first elastic body provided directly on the first lateral extension; and

a third mount device provided on the machine body and connected to the second lateral extension to support the housing, the third mount device comprising a second elastic body provided directly on the second lateral extension.

2. The work machine according to claim 1 , wherein the first lateral extension and the second lateral extension are provided over the rotational axis of the rotary electrical device.

3. The work machine according to claim 1 ,

wherein the first lateral extension overlaps with the first elastic body viewed in the rotational axis of the rotary electrical device, and

wherein the second lateral extension overlaps with the second elastic body viewed in the rotational axis of the rotary electrical device.

4. The work machine according to claim 1 ,

wherein the first lateral extension overlaps with the first elastic body viewed in the height direction which is perpendicular to the first lateral direction and substantially perpendicular to the rotational axis of the rotary electrical device, and

wherein the second lateral extension overlaps with the second elastic body viewed in the height direction of the work vehicle.

5. The work machine according to claim 1 , wherein the connector is provided above the rotational axis of the rotary electrical device in the height direction.

6. The work machine according to claim 1 , wherein the actuator is a hydraulic actuator to be driven by the engine.

7. The work machine according to claim 1 ,

wherein the actuator has a drive shaft to which motive power from at least one of the rotary electrical device and the engine is transmitted, and

wherein the housing accommodates an end of the drive shaft.

8. The work machine according to claim 1 , further comprising:

a work implement mounted to the machine body to be driven by at least one of the engine and the rotary electrical device.

9. The work machine according to claim 1 ,

wherein the housing main body has a first end facing the engine and a second end opposite to the first end along the rotational axis, and

wherein the connector is provided on the second end.

10. The work machine according to claim 9 , wherein the connector is above the actuator in the height direction.

11. The work machine according to claim 1 , wherein the electric power controller is provided above the particulate removal device in the height direction.

12. The work machine according to claim 11 , wherein the particulate removal device is provided between the electric power controller and the rotary electrical device in the height direction.
