Abstract
An excavating and loading machine mounted on a wheeled type vehicle comprising front and rear frames having wheels rotatably mounted thereon, said front and rear frames being adapted to rotate relative to each other, and a vehicle body having an implement for effecting excavation and loading operations which is rotatably mounted on either of said front and rear frames. A pair of hydraulically operated cylinders are provided between said front and rear frames for controlling steering of the vehicle.
Claims4
An excavating and loading machine mounted on a wheeled type vehicle comprising:
- a rear frame having wheels rotatably mounted thereon at both ends thereof, said rear frame having an axial cylinder formed thereon;
- first bearing means mounted on a lower part of the outer periphery of said axial cylinder;
- second bearing means mounted on an upper part of the outer periphery of said axial cylinder;
- a front frame having wheels rotatably mounted thereon at both ends thereof, said front frame being rotatably mounted on said axial cylinder of said rear frame about said first bearing means;
- a vehicle body having an implement for effecting excavation and loading operations, said vehicle body being rotatably mounted on said axial cylinder of said rear frame about said second bearing means;
- first rotating means for rotating said front frame relative to said rear frame about said axial cylinder;
- and
- second rotating means for rotating said vehicle body about said axial cylinder wherein said second means comprises a ring gear fixedly secured to the inner surface of said axial cylinder, and a motor having a pinion attached thereto and fixedly secured to said vehicle body, said ring gear being adapted to mesh with said pinion.
An excavating and loading machine mounted on a wheeled type vehicle, comprising a front frame having wheels rotatably mounted thereon at both ends thereof;
- a rear frame having wheels rotatably mounted thereon at both ends thereof;
- an intermediate frame having an axial cylinder formed thereon, said intermediate frame being pivotally connected to said front and rear frames;
- a vehicle body having an implement for effecting excavation and loading operations which is rotatably mounted on said axial cylinder;
- a pair of hydraulically operated cylinders mounted on both sides of said intermediate frame for interconnecting said front frame and said rear frame;
- rotating means for rotating said vehicle body about said axial cylinder, said rotating means including a ring gear fixedly secured to the inside of said axial cylinder, and a motor having a pinion attached thereto and being fixedly secured to said vehicle body, said ring gear being adapted to mesh with said pinion;
- a bracket fixedly secured to said intermediate frame;
- a bell crank pivotally mounted on said bracket;
- and
- a linkage interconnecting said front frame and said rear frame through said bell crank.
