Description

Technical Field

[0001] This utility model relates to an adjustable height damping leaf spring seat for heavy commercial vehicles, belonging to the field of suspension technology. Background Technology

[0002] Currently, heavy-duty commercial vehicles using non-independent leaf spring suspension structures experience increased suspension skew frequency when fully loaded, leading to poorer ride comfort and reduced leaf spring life. Furthermore, while adjusting suspension height commonly involves changing the leaf spring arc height, this requires developing new leaf springs with varying arc heights for different vehicle models, resulting in a wide variety of types and inconvenient parts management. Utility Model Content

[0003] For heavy-duty commercial vehicles using non-independent leaf spring suspension structures, the increased rear suspension skew frequency after the vehicle is fully loaded leads to poor vehicle ride comfort, reduced leaf spring life, and a common solution for adjusting the rear suspension height is to change the leaf spring arc height. However, if there are many different models with varying height requirements, it is necessary to redevelop leaf springs with different arc heights, resulting in a wide variety of types and inconvenient parts management. The purpose of this utility model is to design an axle leaf spring seat that can alleviate impact vibration, improve vehicle ride comfort and reliability, and facilitate the adjustment of the rear suspension height.

[0004] This utility model is achieved through the following technical solution:

[0005] An adjustable height damping leaf spring seat for heavy commercial vehicles includes an upper support 1, a rubber pad 2, a two-way action cylindrical shock absorber 3, and a rubber-containing lower support 4. The upper support 1 and the rubber-containing lower support 4 are connected by threads at both ends of the two-way action cylindrical shock absorber 3. The rubber pad 2 is placed between the upper support 1 and the rubber-containing lower support 4. The rubber-containing lower support 4 is connected to the axle. The upper support 1 is in contact with the leaf spring.

[0006] This utility model of an adjustable height damping leaf spring seat can improve vehicle ride comfort, increase leaf spring life, reduce vehicle maintenance and usage costs, and avoid frequent leaf spring development. Attached Figure Description

[0007] Figure 1 is a schematic diagram of this utility model, wherein Figure 1a It is an exploded diagram. Figure 1b It is an assembly drawing;

[0008] Figure 2 This is a diagram showing the usage state of this utility model. Detailed Implementation

[0009] As shown in Figure 1, this utility model is an adjustable height damping leaf spring seat for heavy commercial vehicles, including an upper support 1, a rubber pad 2, a bidirectional action cylindrical shock absorber 3, and a rubber-containing lower support 4.

[0010] Support 1 and rubber-containing lower support 4 are connected by threads at both ends of bidirectional action cylindrical vibration damper 3.

[0011] Rubber pad 2 is placed between the upper support 1 and the lower support 4 containing rubber.

[0012] The bridge leaf spring seat of this utility model is used as follows:

[0013] The rubber-containing lower support 4 is connected to the axle, and the upper support 1 is in contact with the leaf spring. The rear suspension height can be adjusted by adding or removing the rubber pads 2. The two-way action telescopic shock absorber 3 and the rubber pads 2 can attenuate the impact vibration transmitted from the ground to improve the ride comfort of the car and increase the life of the leaf spring. The lower support 4 is connected to the axle.

[0014] The utility model is used as follows: Figure 2 As shown.

[0015] This utility model addresses the issue of increased rear suspension skew frequency in heavy-duty commercial vehicles employing non-independent leaf spring suspension structures. Under full load, this leads to decreased ride comfort and reduced leaf spring lifespan. While adjusting rear suspension height commonly involves modifying the leaf spring arc height, this requires developing new leaf springs with varying arc heights for different vehicle models, resulting in a diverse range of types and inconvenient parts management. This axle-mounted leaf spring seat effectively solves these problems, improving ride comfort, increasing leaf spring lifespan, and reducing vehicle maintenance costs. Furthermore, the suspension height can be adjusted by adding or removing rubber pads, avoiding frequent leaf spring development and facilitating parts maintenance and management for R&D personnel. This design shows great promise for practical applications.
