CAMBER
Dynamic rear frame (first version) and Dynamic 2.0
The hole of the cambered receiver, since it is inclined, is not centred.
Therefore, check the wheel receiver its narrow edge looking upward and its wider edge down. If opposite, the convergence is opposite, too
(the wheels are opening apart at top!).
At 30 cm from the floor, take the measure centre-to-centre between the two tyres in front and at rear.
If the two measures are equal or the front one is slightly narrower (max. 5 mm), the convergence could be good as in drawings 2 or 3.
In fact, even if these measures are respected, there may be a wrong adjustment, that is, the wheels could be parallel between themselves
but not with the frame.
Therefore, it is necessary to take the measurement
L
, on both sides of the wheelchair, from a fixed point of the
frame (or of a support fixed to it) to the centre of the tyre.
If the measurements
L
are different, it is necessary to adjust this aspect, too.

RECEIVER
WORK ON A FLAT AND EVEN SURFACE
With cambered wheels, it is necessary to adjust the convergence in order to make the wheelchair very fluent.
The wheel receiver gives the rear wheel camber (cambered receiver).
The receiver is fixed to the rear wheel plate and, to adjust the convergence, it is necessary to turn the same receiver.
The two receivers are independent; therefore, their adjustment is independent, too.
The drawing
1
shows same inclination (camber) of both rear wheels.
With cambered wheels, it is necessary to check/adjust the convergence, the distance between the two wheels in front and at rear.
The drawing
2
shows the aerial view of the wheels and the front distance
DA
is equal to the rear distance
DP
, while the drawing
3
,
DA
is
narrower than
DP
by maximum 5 mm.
We can say that a good convergence has the front distance
DA
equal to or slightly narrower than the rear distance
DP.
DA
must not be wider than
DP
. In such case, the fluency of wheelchair will not be good.
