HTBLAuVA TGM - Racing Team
Austria’s sole representatives will be the Vienna-based HTBLAuVA – TGM
Racing Team is being led by the team’s rider, Martin Loicht.
The TGM RT was founded a decade ago to research the high speed
properties of non-conventional driven motorcycles. The team consists of
two teachers and a number of students, working to improve the
educational and engineering skills and capacities of those involved.
The team set an acknowledged world speed record over 10km and came
close to achieving the record over 1km, but for an engine fault, which
prevented it from landing the accolade.
Team members share a fair amount of experience in racing conventionally
powered bikes and sidecars both off-road and on-road. The basic concept
for the team’s TTXGP motorcycle is derived from its record bike but,
now of course, the new design has been influenced by a decade of
experience.
TGM Racing Team TTXGP entry technical specifications:
• 114 V DC Source provided by LiFePO4 combined of 3x 3 Packs. 3 Packs
serialized for
voltage (3x38V), forming 3 parallel strings.
• Each string separately linked to governor (Curtiss 120V / 500 Amps)
by fuse.
• Each pack singly mounted to substructure in main frame.
• Main frame is forming cage around packs.
• An additional cut-out switch in motorcycle practice on handlebar is
mounted.
• Fuse holder doubling as emergency cut-out switch.
• Drive from Lynch 135RAGS DC motor via clutch and 6 speed gearbox by
chain to rear
wheel.
• The ground potential is defined by resistor and capacitor.
• Each pack includes separate BMS.
• Lower Part of fairing also acting as additional pack containment.
• The air-cooling of packs works by flow from front to left hand rear.
• Motorcycle frame is of welded space frame type made of mild steel
tubing o.d. 28-30mm; wall thickness 1,5mm.
• Front fork is of conventional design, rear suspension complies double
sided swinging arm with twin shocks.
• Suspension travel front 130mm, rear 100mm.
• Tyre dimension front is 90/90/18, rear 110/80/18 or 90/90/18
alternatively.
• Wheels are cast spoke wheels, front brake is 2x 276mm, rear 1x 210mm,
hydraulically
operated disc type.
• NO electrical braking.
• Starting number are displayed on the bodywork of bike, which is made
of aluminum and
fibreglass.
• Fairing stays and rear subframe are made of mild steel. Handlebars,
levers and footrests
are standard motorcycle components, twistgrip acts directly on
potentiometer to provide
reference value for governor.
• Primary and secondary transmission follows standard motorcycle
practice.
• Seat position is conventional (no feet forward).
• Seat height is 710mm unloaded.
• Wheel spindles are made of steel.
• No coolant except air.
• Front fairing encloses front wheel (dustbin type), front wheel
angular movement +/- 15°.
• Minimum ground clearance 45mm for fully compressed suspension, 125mm
loaded.
• Maximum angle of lean is 45° for fully compressed suspension.
• Wheelbase 1460mm, castor angle 65°, trail 100mm, overall vehicle
length 2150mm, vehicle weight about 200kg.
