Work vehicle
A vehicle includes a dynamic shock absorbing mechanism provided in a cabin. The dynamic shock absorbing mechanism includes a weight support member transversely supported at an upper portion of a cabin frame and extending along a transverse width of a vehicle body; and a weight member supported at a center portion in the vehicle body transverse width direction of the weight support member. The weight support member is an elastic member that has a smaller elastic modulus than an elastic modulus of the cabin frame.
1. A vehicle comprising:
a traveling vehicle body;
a driving section formed on the traveling vehicle body;
a cabin having a cabin frame and covering the driving section;
a cushion member interposed between the traveling vehicle body and the cabin supported to the traveling vehicle body;
wherein the cabin includes a dynamic shock absorbing mechanism having a weight support member transversely supported at an upper portion of the cabin frame and extending along a transverse width of the vehicle body, and a weight member supported at a center portion in the vehicle body transverse width direction of the weight support member; and
the weight support member comprises an elastic member that has a smaller elastic modulus than an elastic modulus of the cabin frame.
2. The work vehicle as defined in claim 1 , wherein:
the dynamic shock absorbing mechanism includes:
a front-facing elastic support member extending forwardly along the vehicle body front/rear direction from the center portion in the vehicle body transverse width direction and having a smaller elastic modulus than the elastic modulus of the cabin frame; and
a rear-facing elastic support member extending rearwardly along the vehicle body front/rear direction from the center portion and having a smaller elastic modulus than the elastic modulus of the cabin frame; and
the weight member includes:
a front weight member supported to the center portion via the front-facing elastic support member; and
a rear weight member supported to the center portion via the rear-facing elastic support member.
3. The work vehicle as defined in claim 1 , wherein:
the cabin includes a roof portion; and
the dynamic shock absorbing mechanism is accommodated within the roof portion.
4. The work vehicle as defined in claim 3 , wherein:
the work vehicle further comprises a pair of right and left air-conditioning ducts accommodated in distribution within opposed sides of the roof portion and extending along the vehicle body front/rear direction; and
the weight member of the dynamic shock absorbing mechanism is accommodated between the pair of right and left air-conditioning ducts in the roof portion.
5. A work vehicle comprising:
an engine;
a vehicle body frame including an engine coupling portion to which the engine is coupled, and an extension frame portion extending forwardly or rearwardly in the vehicle body front/rear direction from the engine coupling portion;
a battery supported to the extension frame portion; and
an antivibration member interposed between the extension frame portion and the battery.
6. The work vehicle as defined in claim 5 , wherein
the antivibration member is interposed between the extension frame member and the battery while receiving and supporting the battery from under.
7. The work vehicle as defined in claim 5 , further comprising:
a battery mount on which the battery is placed; and
a fixing tool coupled to the battery and also to the battery mount for fixing the battery to the battery mount;
wherein the antivibration member is interposed between the extension frame portion and the battery mount to which the battery is fixed via the fixing tool.
