合致すると著しい荷痛みが生じる。[Prior Art] Generally, a truck bed is placed on the vehicle frame with a joist such as wood or a thin rubber sheet sandwiched between them.
Since it is connected to the vehicle frame using extremely rigid fastening members such as U-bolts, unsprung vibrations, bending vibrations of the vehicle frame, and sprung mass vibrations are transmitted to the loading platform when the vehicle is running, and these combined vibrations are compared. In particular, when the natural vibration of the load and the vibration of the vehicle match, significant load pain occurs.

型となるばかりでなく、重量の増加を来たし、そ
れだけ積載重量が減るという問題がある。 Therefore, floating support structures have been proposed in which the cargo bed is supported on the vehicle frame via springs, but this can absorb vibrations in the vertical direction, but The loading platform tends to tilt, and it is necessary to install a torque rod or the like between the vehicle frame and the loading platform. However, installing such a torque rod not only increases the size of the structure, but also increases the weight, which causes a problem in that the load weight decreases accordingly.

る。[Effects of the invention] As described above, the invention combines a block-shaped rubber mount between the leaf springs bent into a U-shape, and connects the ends of the leaf springs between the vehicle frame and the subframe that supports the cargo bed. A rubber mount is baked into the inside of the leaf spring bent into a U-shape, and both ends of the leaf spring are sandwiched between the vehicle frame and the subframe. This and the damping effect of the rubber mount suppress vibrations in the vehicle frame caused by changes in the road surface from propagating to the loading platform.
Ｕ字形に折り曲げられた板ばねが前後・左右の
捩れ剛性をもつので、車枠に対する荷台の左右・
前後の傾きが規制される。 The U-shaped leaf springs have torsional rigidity in the front, back, left and right directions, so the loading platform can be bent left and right in relation to the vehicle frame.
The forward and backward inclination is regulated.
また、過大な前後・左右の荷重が加つても、板
ばねが負担するので、ラバーマウントのへたりが
抑えられる。したがつて、ラバーマウントを厚く
できるので、車枠の曲げ振動のように振幅の大き
な振動に対しても有効である。 Additionally, even if excessive front-to-back and left-right loads are applied, the leaf springs bear the load, which prevents the rubber mount from becoming sagging. Therefore, since the rubber mount can be made thicker, it is effective even against large amplitude vibrations such as bending vibrations of the vehicle frame.

が少ない。 Because it is installed in the gap between the vibration damping member, vehicle frame, and subframe, there are no restrictions on installation, and compared to conventional floating support structures, there is no need to install torque rods, which reduces the impact on vehicle weight. There are few degrees.
