Abstract
A steering apparatus for a working vehicle is provided which is capable of steering dirigible wheels by increased steering angles while checking sideways sliding of the wheels on the ground. For this purpose, a pair of right and left intermediate cases are supported by right and left wheel supports of a vehicle body, each to be pivotable about a first steering axis extending substantially vertically. Each intermediate case supports an axle case in a position thereof opposed to the associated dirigible wheel, to be pivotable about a second steering axis extending substantially vertically. The axle case supports the associated dirigible wheel to be rotatable on an axle.
Claims7
A working vehicle comprising:
- a vehicle body;
- a pair of right and left dirigible wheels each having an axle;
- a steering wheel for steering said pair of right and left dirigible wheels;
- a pair of wheel supports arranged in right and left positions of said vehicle body;
- intermediate cases each supported by one of said wheel supports to be pivotable relative to said one of said wheel supports about a first steering axis extending substantially vertically;
- axle cases each attached to a side of one of said intermediate cases opposed to one of said dirigible wheels for supporting said one of said dirigible wheels on one of said axles, each of said axle cases being pivotable relative to one of said intermediate cases about a second steering axis extending substantially vertically;
- and
- a steering control mechanism operable in response to turning of said steering wheel for swinging each of said intermediate cases about said first steering axis and swinging each of said axle cases about said second steering axis, thereby steering said pair of dirigible wheels relative to said vehicle body.
