Dual Torsion Spring

Solution

Double Torsion Spring Assisted By Steering Gear

This dual torsion spring assisted manual steering gear system is made of high-strength alloy steel and has undergone precision heat treatment to ensure high elasticity and long-lasting durability. The dual torsion spring design provides precise torque output, making the steering system more stable and sensitive, reducing the labor burden during driving. The bidirectional torque of the torsion spring enhances the responsiveness and stability of the system, ensuring easier and more comfortable control. It is suitable for a variety of manual steering systems, which can effectively improve the driving experience, reduce wear and tear, and extend the service life of gears and other components. Its excellent corrosion resistance, fatigue resistance and high temperature resistance make it adaptable to various driving environments, especially in harsh conditions.

Applications

Automotive: Used in car door latches, seat recliners, and steering mechanisms to provide rotational force and control movement.

Appliances: Common in devices like washing machines, dryers, and refrigerators for door closing mechanisms and rotational parts.

Furniture: Applied in furniture mechanisms, such as reclining chairs and adjustable desks, where dual torsion springs enable smooth and controlled movement.

Electronics: Used in devices like cameras, printers, and switches for smooth, controlled operation of mechanical parts.

Industrial Machinery: Provides torque for various equipment, including conveyors and locking mechanisms, ensuring precise control of rotating components.

Toys and Recreational Devices: Found in wind-up toys, mechanical games, and other devices that require a compact, reliable spring to store and release energy.

Heavy Machinery: Dual torsion springs are used to manage tension and release energy in large industrial machines, such as cranes or elevators, to ensure smooth operation.

FAQ

1. What is a dual torsion spring?
A dual torsion spring consists of two torsion coils connected by a central leg, wound in opposite directions (left-hand and right-hand). It is designed to provide balanced torque in both directions, commonly used in applications that require rotational force from both sides.

2. What are the main applications of dual torsion springs?
Dual torsion springs are widely used in:

• Garage doors

• Automotive mechanisms (e.g., trunk lids, pedals, gear shifters)

• Industrial equipment

• Medical devices

• Agricultural tools

• Mechanical assemblies requiring bi-directional torque

3. Can you customize the spring dimensions and torque specifications?
Yes, we offer full OEM/ODM customization including:

• Wire diameter

• Coil diameter

• Leg length and angle

• Material

• Torque and load requirements
  We support drawings, samples, or custom development based on application needs.

4. What materials are used for dual torsion springs?
Common materials include:

• Music wire

• Stainless steel (302, 304, 316)

• Phosphor bronze

• Carbon steel

• Pre-hardened spring steel
  Surface treatments like zinc plating, black oxide, and electrophoresis are also available.

5. What is the typical lead time for production?

• Standard samples: 3–7 working days

• Custom samples: 7–14 days
