About this creation
Lego Tatra T813 RC 4x4 Trial Truck V4
The famous Tatra T813 in Lego remote controlled version, versatile and durable as the original.
The scale model made by me after several months of work, contains most of the features found in the real version, to significantly affect its performance are the axle shafts, transmission, suspension, chassis structure and weight distribution.
-height: 225,0mm, 22,50cm
-lenght: 400,0mm, 40,00cm
-width: 215,0mm, 21,50cm
-3 XL Motors (2 for drive, 1 for sterring), 2 IR Receviers, 2 Battery Boxes
For Lego Tatra T813 I opted for the use of two XL Motors, which provide a high torque with an average consumption of energy, but low number of revolutions per minute. There are two transmission shafts (the real Tatra T813 uses one), each connected to a single engine, split the load energy, strengthen the chassis, but also to divide the stress that every engine needs to support. In the gear shaft there are numerous gear reductions with anti-snapping patented by me (final gear ratio 9:1).
Independent half-axles suspensions for each wheel, all-wheel drive and anti-snapping system between gears for maximum traction, unlike the original model, Lego Tatra T813 does not use differential: between Lego bricks there is no type of limited-slip differential, then, by inserting a differential whatever, at the first hurdle would stop the vehicle, and this should not happen.
New axle shafts very strong, with anti-snapping system patented by me, gear reductions, increased torque transmitted to the wheels (final gear ratio 9:1), and steering (in the front).
Individual tactical tires on each axle (94.3 x 38R).
Comparison with the real model
The Lego model made by me is very similar to the real one, in particular, the design of the cabin faithfully reproduced it based on original designs.
