Torque Drive Axle Brings Smoothness
A high-torque drive axle offers strong startup and acceleration performance. Within a very short period of time, it can achieve higher startup speeds. This acceleration experience gives drivers a sense of smoothness in the vehicle. Vehicles with high-torque drive axles reduced acceleration time by an average of 15% in actual tests, improving not only driving efficiency but also vehicle responsiveness. An advantage of this drive axle is in city driving conditions, where frequent stop-and-go is required. It does not require drivers to worry about possible acceleration lag or body shake in these conditions.
With the use of a high-torque electric drive axle, maximum torque during acceleration can exceed 300 Nm, enabling the vehicle to complete rapid acceleration over a very short distance. This provides a smoother driving experience, especially in situations requiring frequent braking and restarting, where the high-torque drive axle shows significant advantages. High-torque drive axles also reduce wheel slipping, particularly on slippery roads. Vehicles with high-torque drive axles showed an increase in grip on wet roads by 18%, thus improving not only safety but also providing a smoother driving experience.
Quiet Drive Axle Makes Driving Quieter
A noise reduction design can efficiently make electric drive axles in the range of 150 W to 20 kW operate much more quietly. As a result, a vehicle equipped with quiet drive axles can reduce noise by as much as 35%. This quietness becomes more noticeable during low-speed driving or in city traffic. This not only enhances driver comfort but also minimizes disturbances to passengers. By using quality materials and precision processes, Rotontek’s electric drive axle products significantly reduce mechanical noise during operation. Taking full advantage of noise-reducing materials and optimized gear design, the operating noise of the products can be less than 60 decibels—around the volume of everyday conversation—which significantly enhances the quietness of the vehicle’s interior.
Under normal conditions with the same power, the noise of an electric drive axle can reach as high as 80 decibels, but quiet ones using noise reduction technology generate just 50–60 decibels, and this difference makes the driving environment much smoother. Especially during long drives, continuous low noise can greatly reduce driver fatigue and improve the overall ride experience. This quiet effect not only improves passenger comfort but also makes communication inside the vehicle easier. Quiet drive axles also reduce resonance—a phenomenon caused by high-frequency vibration—through precision gear sets and optimized motor operating efficiency. This further enhances the quiet experience inside the vehicle, and during long drives, passengers can barely notice the noise emitted by the drive system.
Shock Absorption Performance Improves Ride Comfort
While the electric drive axle significantly improves acceleration and smoothness, its excellent shock absorption performance is also a crucial factor in vehicle comfort. For electric drive axles within the power rating scope of 150 W–20 kW, shock absorption technology is particularly important, especially when passing over bumpy roads. The responsiveness and capability of the drive axle to absorb vibrations can directly affect the ride quality. Advanced shock absorption systems equipped in electric drive axles can effectively reduce road vibration transmission by more than 30%. During driving, the vibration felt inside the car is significantly reduced. Such a shock absorption effect is most remarkable during high-speed driving or when driving on rough roads. This performance not only meets the demand for comfort in daily city driving but also satisfies the needs of comfort during long-distance travel.
As widely used in the industry, hydraulic shock absorption systems are also applied to electric drive axles. A series of drive axle products with hydraulic shock absorption use a combination of shock absorption pads and high-strength springs, reducing vibration amplitude to within 5 mm even on extremely rough roads. This small vibration is almost imperceptible to passengers, greatly improving the ride experience. In addition to shock absorption technology, the dynamic response capability of the electric drive axle is also important. An adjustment device inside the drive axle can adjust shock absorption parameters in real time according to road and speed conditions to ensure that the vehicle offers optimal smoothness under any circumstances. This becomes especially important in city traffic, where frequent acceleration, deceleration, and turning do not cause unnecessary shaking and discomfort.
Efficient Drive Axle Makes Driving More Worry-Free
An efficient electric drive axle makes a significant improvement in vehicle energy efficiency, making driving more worry-free. By improving the efficiency of converting electrical energy, the vehicle’s range can be effectively extended. This results in a significant difference in energy consumption, reflecting the advantages of an efficient drive axle and reducing daily electrical costs, making driving more economical. Another key factor is the heat dissipation of the efficient drive axle. During long drives, the temperature of an electric drive axle has often been an important factor affecting performance. One drive axle product employs advanced liquid cooling technology, where during long-distance driving, the temperature of the drive axle can be maintained below 75 degrees Celsius. As a result, this significantly reduces power attenuation due to overheating. That means drivers will have no reason to be concerned when traversing different types of roads, as their vehicle performance will not be compromised.
