Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a balance shaft suspension for heavy-duty vehicles. Background Technology

[0002] The suspension system is a collective term for the elastic and damping devices between the vehicle frame and axles. Its function is to elastically connect the axles and frame, mitigate impact forces experienced by the vehicle during driving, and ensure the integrity of cargo and passenger comfort. In multi-axle medium and heavy-duty commercial vehicles, the rear suspension often uses a balance shaft suspension, utilizing the balance shaft to bear weight and regulate and control rear axle movement. According to experimental data, a 10% reduction in vehicle weight can improve fuel efficiency by 5.5%. With the development of lightweight vehicles, weight reduction and performance improvement are receiving increasing attention, and major automakers have made lightweight components a key development direction. Especially in the heavy-duty truck sector, lightweighting has become a competitive goal for automakers; only lightweighting can reduce fuel consumption, emissions, and improve the range of new energy vehicles. Currently, the balance shaft suspension has excessive redundancy, excessive weight, and high cost, making it difficult to meet the needs of lightweight vehicles. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a balance shaft suspension for heavy-duty vehicles. Through structural optimization, the weight is reduced and the cost is lowered, thus meeting the needs of lightweight vehicles.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a heavy-duty vehicle balance shaft suspension, comprising a main body, on which a saddle seat, a balance bar connecting seat, a balance shaft bracket, a first connecting plate, and a second connecting plate are provided, integrating multiple functions into one, realizing integrated modular design and production.

[0005] The saddle seat is located on the top of the main body. The saddle seat includes two symmetrically arranged seats. Under the premise of ensuring the structural strength of the saddle seat, a first U-shaped weight-reducing groove is provided between the two seats. The inner corners of the first U-shaped weight-reducing groove are rounded to avoid cracking. Multiple first bases are arranged on the seats, and the multiple first bases form a square array structure. A first connecting through hole is provided on the first base.

[0006] The stabilizer bar connector is located at the bottom of the main body. The stabilizer bar connector includes a first connector and a second connector. The first connector is arranged vertically, and the second connector is arranged at an angle relative to the first connector. Both the first and second connectors have through holes for connection. While ensuring the structural strength of the stabilizer bar connector, a second U-shaped weight-reducing groove is provided between the first and second connectors. The weight-reducing groove is provided on the inner side of the first connector to further reduce its weight. The weight-reducing groove is provided on the inner side of the second connector to further reduce its weight.

[0007] The balance shaft bracket is located in the middle of the main body, perpendicular to the main body, and below the saddle seat. The balance shaft bracket has a balance shaft hole coaxially opened on it.

[0008] The first connecting plate is arranged on one side of the main body. One side of the first connecting plate is connected to the main body through the first stiffener, and the other side of the first connecting plate is connected to the main body through the second stiffener. The first stiffener and the second stiffener can increase the connection strength between the first connecting plate and the main body. A third U-shaped weight-reducing groove is provided between the first connecting plate and the main body to further reduce the weight of the entire structure. Multiple connecting through holes are opened on the first connecting plate.

[0009] The second connecting plate is arranged on the same side of the main body as the first connecting plate. The second connecting plate is arranged at the bottom of the main body and is perpendicular to the first connecting plate. Multiple connecting through holes are opened on the second connecting plate.

[0010] The first and second stiffening plates are arranged in parallel and supported by the first and second support plates. The balance shaft hole of the first support plate is arranged between the first and second support plates. A square weight-reducing groove is formed between the first support plate, the first connecting plate, the first stiffening plate, and the second stiffening plate. The balance shaft hole is placed between the first and second support plates, forming a square weight-reducing groove between the first and second support plates and between the first and second stiffening plates. A triangular weight-reducing groove is formed between the second support plate and the first and second stiffening plates. This multi-weight-reducing groove design greatly reduces the weight of the entire structure.

[0011] A first triangular support plate is arranged on one side of the main body, between the first stiffener plate and the saddle seat. The first stiffener plate can increase the connection strength between the saddle seat and the main body. A second triangular support plate is arranged on the other side of the main body, between the second stiffener plate and the saddle seat. The second stiffener plate can increase the connection strength between the saddle seat and the main body.

[0012] Compared with the prior art, the specific beneficial effects of this utility model are as follows: This utility model removes excess material through structural optimization, and the optimized weight is 112kg, which is a weight reduction of 15.1%; the optimized safety factor of this utility model reaches 1.86, eliminating the inherent defects of key sections, and using QT1050-7 material, the strength is greatly increased; this utility model integrates five modules: balance shaft saddle, V-thrust rod support, transmission support, ball joint bracket, and upper and lower connecting crossbeams, realizing integrated modular design and production, reducing production costs by 26%, and meeting the needs of lightweight automobiles.
