Tyron's
rotary runflat composite roller system fits inside the
standard wheel and tyre assembly to provide an extended
runflat capability. Whether one or more tyres fail through
high-speed blow-out, terrorist attack or simple puncture,
Tyron rotary runflat provides a safe runflat performance,
helping the driver maintain steering, cornering and braking
control. The vehicle can then continue to be driven on
the flat tyres to 50+ km, to a safe place to change the
wheel.
STATIC
RUN-FLAT System
The
Static Run-Flat System consists of two segments
that are assembled around the wheel drop center
and one that is locked together with nuts and
bolts.
Significantly
reduces tire abrasion
High impact performance over extreme temperature
ranges
Low heat build up in flexing
Light weight system that provides high load bearing
and exceptional energy absorption, that withstands
significant vehicle payload
Economical system and life cycle cost
System installation is simple without the need for
special tools. It is also easy to remount
Long life and durability
DESIGN
FEATURE
The
secret of Tyron's rotary runflat success is that its design
consists of an outer roller fitted around an inner runner
in the wheel's well. The outer roller remains static in
normal operation but revolves around the inner runner when
running deflated, as the vehicle's weight is applied. Without
this rotating outer section, slippage (caused by the difference
between the circumference of the deflated tyre and smaller
circumference of the runflat system inside) would create
high levels of friction and excessive heat build up. The
tyre's beads would also be easily dislodged, severely reducing
traction, braking and steering performance. The system
requires no lubrication inside the tyre.
PROTECTING
THE WHEEL & TYRE
Tyron
rotary runflat is mounted to the rim inside the tyre and
does not come into contact with the tyre until it deflates.
When running deflated Tyron rotary runflat supports the
tyre's tread and prevents the side walls from being damaged
by the rim.
LONG
RUNFLAT
Tyron's
design allows for long runflat distances without excessive
heat build-up, while normally trapping at least one of
the tyre's beads, maintaining traction and driver control.
This is a significant advantage over fixed runflat systems.
For even greater control in extreme runflat situations
an optional full 'beadlock' may be built into the system.
SERVICING
As
it does not rotate in normal operation Tyron rotary runflat
requires little or no servicing and normal balancing can
be carried out. ABS braking is also unaffected.
CRITICAL
POINT
Tyres
totally disintegrate by the time they have reached their
vulcanisation temperature of 180 deg. C. Tyron's rotary runflat
is manufactured in polyester elastomer with a melting temperature
in excess of 200 deg. C. With a high strength to weight ratio
Tyron rotary runflat is lighter than solid rubber systems.
In the event of a ballistic attack Tyron's high shock absorbent
material allows a bullet to pass straight through without
the unit shattering.(Test data available).
Operating
temperature range: Operational -43¼C (-46¼F)
Storage -48¼C (-54¼F) to in excess of 200¼C
(390¼F).
RUNFLAT
PERFORMANCES
Run-Flat
Systems can be used in all cars and light trucks
to provide mobility in the event of tire failure,
so that driving can continue for up to 50 Km. The
Run-Flat System will allow the vehicle to maintain
steering control and mobility in the case of tire
blow out at high speed. Specific applications of
the Run-Flat Systems are as follows:
up
to 15km Runflat
30
- 50km Runflat
up
to 50km Runflat
