What is the difference between double wishbone and double transverse arm?
2 Answers
The difference between double wishbone and double transverse arm is introduced as follows: 1. Different in nature: Double wishbone suspension, also known as double A-arm independent suspension, has upper and lower wishbones that simultaneously absorb lateral forces, with the strut only bearing the weight of the vehicle body; Double transverse arm suspension refers to a suspension system with two transverse arms. 2. Different in applicability: Double wishbone suspension excels in sportiness and is used by supercars such as Ferrari and Maserati; Double transverse arm suspension is widely used in the front and rear suspensions of sedans. Both double wishbone and double transverse arm belong to independent suspensions. Simply put, the difference between them is that double wishbone is one level higher than double transverse arm. In fact, double wishbone and double transverse arm can be classified into the same category, with double transverse arm being considered a simplified version of double wishbone. The design of double transverse arm suspension leans towards sportiness.
In automotive suspension systems, the double-wishbone typically refers to a type with upper and lower control arms arranged horizontally, as seen in the front suspension of most high-end sedans. It allows the wheels to remain vertical over bumps, enhancing tire grip, providing good stability when driving, and minimizing body roll during cornering. On the other hand, the double trailing arm is more commonly found in older vehicles, especially in the rear suspension position. It has a simpler structure, relying on one or two longitudinal arms to control the wheels, but its handling performance is generally average. For example, it is highly adaptable in off-road vehicles but tends to be stiffer and less effective at filtering out bumps. The main differences lie in the orientation of the arms and their performance: double-wishbone focuses on precise handling, while double trailing arms prioritize durability and simplicity. When it comes to repairs, replacing parts for a double-wishbone suspension is more expensive due to its complex components, whereas double trailing arms are cheaper to replace. In summary, when choosing a car, a double-wishbone front suspension is often used to enhance the driving experience, while a double trailing arm rear suspension may be employed to save costs.
