On Portale TIBUS G 460 / 461 / 463
What you might want to know about portal axles: Front and rear axles are rigid axles with portals, this means that the axle tube and the differential housing are situated above the wheel centre.
The portal reduction guides the power to the wheels. Portals will give your vehicle a unique ground clearance. The portal gear ratio reduces the load on the complete drive train since the torque acts only on the wheel. Our solution ensures that the suitability for daily use and the maximum speed is maintained and that the ABS is also working as usual. “Bolt On Portals” are portals that are installed on the existing axles. They are designed in order to maintain the rotating direction of the axles. This is accomplished by using 4 cogwheels in the portal. Another advantage of using 4 cogwheels is that the load is distributed to the tooth flanks of several cogwheels so that more power can be transmitted while the increase in temperature is considerably lower. A portal gear ratio of 1,16-1 is equivalent to the reduction of the load on the axles. Of course, the overall axle ratio changes corresponding to the factor 1,16, which makes it possible to drive large wheels without having to adjust the gear ratio of the differentials. The portals will give the vehicle a “lift” of about 4 inches (10 cm). No further modifications have to be made to the suspension in order to drive larger wheels and the entire axle and steering geometry is maintained. This is the only way to really achieve a proper ground clearance. The additional ground clearance under the differential is 10 cm due to the portals plus the additional ground clearance through the use of larger wheels; wheels that are 25 cm larger than those you normally would drive. There is actually no need to mention that wheels that are 25 cm larger would mean certain death for most axles, let alone the expense for the expensive modifications that are necessary to install such large wheels. The portal kit contains the following parts: 4 portal boxes with pre-installed gear units, 2 outer front steering knuckles, 2 new HD front CV joints, 2 new HD rear axle shafts, 2 rear brake callipers with integrated parking brake, 1 set of front and rear axle clamps, 4 new ABS sensors, mounting bolts.
