Electrification is key to Zero Emission
When it comes to the way vehicles are manufactured, eMobility is leading to a significant shift in how transmission design is approached. The rapid development of electric transition has led the introduction of a series of different architectures for traction, let's see them in review and let's understand the pros and cons.
A transaxle is an integrated component which combines the gearbox function of a transmission with the power-splitting ability of a differential. Shafts for both the left- and right-side drive axles themselves are directly connected to each side of the transaxle bring motion to wheels.
A wheel drive is an integrated gearbox transmission unit without the power-splitting ability of a differential, for this reason you need t oinstall two wheel drives per axle. The gearbox (planetary type) is directly connected to wheel hub and it's installed inside the wheel.
Transaxle or Wheel Drives?
While many operating principles of electric vehicle transmissions differ from their combustion engine vehicle counterparts, at the component level there are actually many similarities in the required design and manufacturing processes. Both solutions could be great, infact none fully prevail over the other given the different characteristics that make both transaxles and wheeldrives applicable depending on the type of vehicle and the kind of performances to be obtained.
The surface finish of the gears also becomes important in electric cars, the noise emission of the transmission is a critical factor due to the quietness of the electric motor. Key components such as straight, helical gears and housings are common to both types of drivetrains. The main challenge in making such components for electric vehicle transmissions is managing the higher torque and rotational speed that can be achieved with electric motors. The tolerances involved in precision manufacturing of transmission components such as straight and helical gears or planetary drive systems are typically narrower for electric vehicle components.
Switch to Zero Emission
By 2035 EU proposes a 100% emission cut, effectively banning internal combustion engine vehicles and even hybrid. Don't be late, think about the future and start your project now
We are offering a fully electric alternative to the conventional internal combustion engines and axial piston hydraulic units, allowing the machine to reduce noise levels and CO2 emissions to zero.
