What are the different types of lower steering axles

The lower steering shaft refers to the part that connects from the steering wheel to the bottom of the steering system, usually used in front-wheel drive or rear-wheel drive vehicles. Its main function is to transmit the driver's steering input to the steering device so that the vehicle can change direction. According to the design and use requirements, the common types of lower steering shafts are as follows:

Straight lower steering shaft

The straight lower steering shaft is the most basic design and is usually used in steering systems with simple structures. It transmits the steering force directly from the steering wheel to the steering gear through a straight shaft, and is suitable for vehicles with more spacious space.

Adjustable lower steering shaft

The design of the adjustable lower steering shaft allows its length or angle to be adjusted as needed. It is often used in vehicles that need to provide personalized adjustments, especially luxury models or some high-end sports cars. It allows the driver to adjust the position of the steering wheel according to personal needs and improve driving comfort.

Folding lower steering shaft

The design of the folding lower steering shaft takes safety into consideration and is usually used in models with higher collision safety requirements. Its structure allows the shaft to be folded or shortened in the event of a collision, thereby reducing damage to the driver. The folding design usually uses flexible materials or special structures to ensure the collision safety of the vehicle.

Universal joint lower steering shaft

Universal joints are used in the design of universal joint lower steering shafts, which allows the steering system to move flexibly in multiple directions. This type of lower steering shaft is often used in situations where the front or chassis space of the vehicle is relatively small, especially for models such as SUVs or off-road vehicles that require a wide range of steering.

Two-stage lower steering shaft

Two-stage lower steering shafts consist of two retractable parts and are usually used in vehicles that require more flexible or efficient steering. They can be extended and retracted as needed during steering, adapt to different driving conditions, and absorb impact forces in collisions to improve vehicle safety.

Aluminum alloy lower steering shaft

In order to reduce weight and improve fuel economy, some modern vehicles use aluminum alloy materials to manufacture lower steering shafts. Aluminum alloy steering shafts have high strength and low weight, which can effectively reduce the overall mass of the vehicle, especially for models that require lightweight design.

Electric power steering lower steering shaft

Electric power steering system is a widely used technology in recent years. Many cars use this system to reduce the steering burden of the driver. In the EPS system, the lower steering shaft is usually integrated with an electric motor or servo, which can provide appropriate steering assistance according to the driver's needs.

Composite lower steering shaft

Composite lower steering shafts are usually made of carbon fiber or other high-strength composite materials, which are both lightweight and high-strength. They are mostly used in high-performance vehicles or racing cars, which can effectively reduce the weight of the steering shaft while improving the vehicle's handling performance and response speed.

Lower steering shaft with sensor

The lower steering shaft with sensor is usually equipped with a steering angle sensor for real-time monitoring and feedback of steering data. Such a design is mainly used in vehicles that require electronic control systems, especially in autonomous driving or driving assistance systems, and provides steering data support in real time through sensors.

Dual steering shaft system

Dual steering shafts are usually found in vehicles that require more complex steering mechanisms, especially some large vehicles or special vehicles. It transmits steering input to two different steering systems through a dual connection design, making steering more flexible and precise.

There are many types of lower steering shafts, which are selected according to the purpose of the vehicle, safety requirements, driving performance and comfort. With the continuous advancement of technology, modern lower steering shafts not only focus on weight and strength, but also enhance intelligence, comfort and safety. Especially with the support of electric power assistance and intelligent driving systems, the advancement of steering technology continues to promote the development of the automotive industry.
