Driving an articulated bus
The turning radii and clearances of an articulated bus de-
pend on the body overhang, wheelbase, location of fifth
wheel and the steering ratio between the fifth wheel and the
wheels of the trailer coach. The illustration shows the steer-
ing geometry of an articulated bus with steering trailer
coach.
The difference between the outer turning radius (A) and the
inner turning radius (B) is the turning breadth.
The B10M articulated bus consists of a tractor coach, corre-
sponding to a normal twin axle bus, and a trailer coach. The
tractor and trailer coaches are connected together through
a fifth wheel and a gaiter. The trailer coach is available in
two versions; with steering and without steering wheels.
The following applies only to articulated buses with steered
trailer coach as this is the most common design.
The trailer coach wheels are steered via link rods connect-
ed to the fifth wheel. As a change in angle occurs between
the tractor and trailer coaches, the wheels will always turn to
a certain degree so that the trailer coach follows the tractor
coach. This reduces the space needed for turning. The dif-
ferences in driving characteristics between an articulated
bus with steered trailer coach and a normal twin axle bus
are not especially great. Only in extreme situations can the
swing of the trailer coach be so great that special caution
need be observed, for example, when leaving a bus stop
bay where the tractor and trailer coaches have been
stopped in a straight line and close to the kerb. In such cas-
es, full steering wheel lock should be avoided. If an obstacle
requires full steering lock, there must be enough room for
the rear end of the trailer coach to swing out approx. 0.5 m to
the side.
