Sinotruk: Shock Absorber Technology Drives the Performance Upgrade of Heavy - duty Trucks

From the export models, we can see the considerations of SINOTRUK in the selection of shock absorbers. Take the HOWO V7X export model as an example. The driver's seat adopts variable hydraulic damping shock absorption. This shock absorption method can adjust the softness and hardness according to the regulator beside the seat, and it also has an inclination adjustment function. Compared with airbag seats, it has better quality and durability, and is especially suitable for the complex road conditions overseas. In many developing countries, the road conditions are poor, with a majority of unpaved roads, and heavy-duty transportation is common. The variable hydraulic damping shock absorption seat can better adapt to such an environment, reduce driver fatigue, and ensure driving safety and comfort. This is one of the reasons why SINOTRUK's export models are popular in overseas markets. In 2024, SINOTRUK exported 134,000 heavy trucks, a year-on-year increase of 3.1%. It has ranked first in the export of China's heavy truck industry for twenty consecutive years. The reliability of product quality, including components such as shock absorbers, has contributed significantly.

Ensure driving stability: When a heavy truck is driving, the wheels will vibrate due to the impact of the road surface. The shock absorber can quickly dampen these vibrations and prevent them from being transmitted to the vehicle body. When transporting heavy goods such as building materials and driving on bumpy construction site roads, the shock absorber can effectively reduce the shaking of the vehicle body, making the vehicle drive more smoothly, reducing the risk of cargo displacement and falling, and ensuring transportation safety.
Improve driving and riding comfort: For heavy truck drivers on long - distance drives, comfort is of crucial importance. A shock absorber with good performance can reduce the impact of road bumps on the cab. During long - distance transportation, the driver will not feel fatigued due to frequent vibrations, improving driving comfort and indirectly enhancing transportation efficiency. For example, in cold - chain transportation, the driver needs to drive for a long time, and a comfortable driving and riding environment helps to maintain energy and ensure that the goods are delivered on time and safely.
Prolong the lifespan of vehicle components: The shock absorber can reduce the wear of various vehicle components caused by vibration. Components such as the heavy truck engine and transmission can operate more stably in an environment with less vibration, the wear of components is slowed down, the number of maintenance and repairs is reduced, the operating cost is lowered, and the overall service life of the vehicle is extended.

Sinotruk continues to invest in research and development and pursues innovation in shock absorber technology. In the future, with the application of intelligent networking and new energy technologies in the heavy - truck field, shock absorbers will also develop towards intelligence and self - adaptation. Sensors are used to monitor road conditions and vehicle driving status in real - time, and automatically adjust the shock absorber damping to provide the best shock - absorbing effect for the vehicle.The research and development of shock absorbers adapted to the characteristics of new energy heavy - duty trucks is also underway, meeting the requirements of new energy heavy - duty trucks for lightweight and high - efficiency.
Sinotruk's practices and explorations in shock absorber technology are important factors for it to maintain its competitiveness in the industry. With technological advancements, shock absorbers will play a more crucial role in enhancing the performance of heavy - duty trucks and expanding the market, helping Sinotruk to continue its journey in both domestic and international markets.
