Kiristysjousi

A kiristysjousi, also known as a tension spring or extension spring, is a type of spring designed to operate under tensile (pulling) forces. It is characterized by its ability to store mechanical energy when stretched and to return to its original shape once the force is removed. These springs are commonly used in applications where a pulling force is needed to maintain tension or to return a component to a specific position.

Typically made from high-strength steel or other durable alloys, kiristysjousi features coils or loops that are tightly wound during manufacturing. The ends of the spring are often configured with hooks, rings, or other attachment points to connect to different mechanical parts. When an external force pulls on the spring, it elongates, and the inherent elasticity resists this extension, creating a restoring force proportional to the stretch according to Hooke's law.

Kiristysjousi are widely employed in various industries, including automotive, manufacturing, and consumer electronics. For example, they are used in vehicle suspensions, trampolines, and mechanical devices requiring tension control or return mechanisms. Proper selection of material properties, coil diameter, length, and attachment method is essential to ensure performance and safety in specific applications.

In summary, a kiristysjousi is a key component in systems requiring controlled extension movement, providing resilience and maintaining tension within mechanical assemblies. Its design and material composition are tailored to meet specific force and durability requirements across diverse fields.
