Abstract
An electric work vehicle includes a housing, a first motor connected to a first gearing to drive a first wheel, the first motor being supported by the housing, a second motor to a second gearing to drive a second wheel, the second motor being supported by the housing, a first shift rod to shift the first gearing between a first position of the first gearing and a second position of the first gearing, a second shift rod to shift the second gearing between a first position of the second gearing and a second position of the second gearing, and a cam to be rotated between a first cam position and a second cam position.
Claims19
An electric work vehicle comprising:
- a housing;
- a first motor connected to a first gearing to drive a first wheel, the first motor being supported by the housing;
- a second motor connected to a second gearing to drive a second wheel, the second motor being supported by the housing;
- a first shift rod to shift the first gearing between a first position of the first gearing and a second position of the first gearing;
- a second shift rod to shift the second gearing between a first position of the second gearing and a second position of the second gearing;
- and
- a cam to be rotated between a first cam position and a second cam position;
- wherein
- a first distance between an inner end of the first shift rod and an inner end of the second shift rod when the cam is in the first cam position is less than a second distance between the inner end of the first shift rod and the inner end of the second right rod when the cam is in the second cam position;
- and
- the inner end of the first shift rod and the inner end of the second shift rod are biased towards each other on a same axis.
An electric work vehicle comprising:
- a housing;
- a first motor connected to a first gearing to drive a first wheel, the first motor being supported by the housing;
- a second motor connected to a second gearing to drive a second wheel, the second motor being supported by the housing;
- a first shift rod to shift the first gearing between a first position of the first gearing and a second position of the first gearing;
- a second shift rod to shift the second gearing between a first position of the second gearing and a second position of the second gearing;
- and
- a cam to be rotated between a first cam position and a second cam position;
- wherein
- a first distance between an inner end of the first shift rod and an inner end of the second shift rod when the cam is in the first cam position is less than a second distance between the inner end of the first shift rod and the inner end of the second right rod when the cam is in the second cam position;
- the cam is driven by a rotational actuator which rotates the cam in a first direction to enter a low range, and which rotates the cam in a second direction to enter a high range;
- the first direction is opposite to the second direction;
- and
- the housing houses the first motor, the second motor, the first gearing, the second gearing, the first shift rod, the second shift rod, and the cam.
