Toyota Old Man Emu Leaf Springs

Here are some key features and characteristics associated with Old Man Emu Dakar leaf springs:

Draw Tapered and Diamond Cut Leaves: Old Man Emu leaf springs incorporate draw tapered and diamond-cut leaves. The draw tapering and diamond cutting of the leaves gradually distribute the load over a larger surface area. By reducing the stress concentrations at the leaf ends, this design enhances ride quality and protects against leaf breakage. The progressive load distribution contributes to increased spring life and ensures optimal performance under varying loads.

Bolt Clamps and Liners: The leaf clamps of these springs leaf springs are bolted, allowing for the installation of anti-squeak nylon liners. This design feature provides a secure attachment and addresses potential noise issues by incorporating liners that minimize friction between the leaves. The use of bolt clamps facilitates easy maintenance and replacement if needed.

Fully Scragged and Load Tested: Each spring undergoes a comprehensive scragging process to ensure they take a permanent 'set.' This reduces the risk of sagging over time. Additionally, load testing is conducted to verify that the spring meets the required specifications, confirming its strength and load-carrying capacity. This dual process ensures the longevity and reliability of the leaf springs in various applications.

Military Wrap: The inclusion of a military wrap in the design of Old Man Emu leaf springs provides added safety. The military wrap involves an additional leaf that wraps around the main leaf, enhancing the overall strength and resilience of the spring. Military applications inspire this design feature and contribute to the durability and performance of the leaf springs.

Anti-Friction Pads: Featured are anti-friction pads, which are grazeable nylon interleaf liners. These pads reduce friction at the leaf tips, especially where the load is the greatest. By minimizing friction, the anti-friction pads contribute to a smoother ride, reduce noise, and enhance the overall performance and longevity of the leaf springs.

Flat Axle Seat Area: The design of Old Man Emu leaf springs incorporates a flat axle seat area. This feature allows for a positive and safe axle mount, reducing spring stress. The flat axle seat area contributes to increased spring life by ensuring a secure and stable connection between the leaf spring and the axle, even under heavy loads or off-road conditions.

Shot Peening: Shot peening on the tension side of all leaves is a process where the surface of the material is bombarded with small, spherical shots. In the context of leaf springs, shot peening reduces spring stress. This process can effectively double the life of a spring by enhancing its resistance to fatigue and potential failure.

Two-Stage Leaf Pack: Old Man Emu rear leaf springs often feature a two-stage leaf pack. This design optimizes comfort by providing a primary and secondary stage. When unloaded, the vehicle rides on the softer initial stage for a comfortable ride. The secondary stage comes into play when a heavy load is added, providing additional support and maintaining stability, making it suitable for various load-carrying scenarios.
