Leaf springs are essentially obsolete in terms of automobile suspension. However, when it comes to the suspension of heavy-duty commercial vehicles like trucks, trailers, and vans. One of the most popular options for sustaining the suspension is still using leaf springs. Before summarizing the reasons why you would choose leaf springs for your can, truck, pickup, bus, or trailer, we will look at a brief history of leaf springs and the benefits and drawbacks of the current leaf spring.
A brief history
Leaf springs may be traced back to the ROᴍᴀɴ era, when they were first used for dampening chariots when they were employed on difficult terrain. The springs were unchanged for a long time before the first sʜᴏᴄᴋ absorber was developed around the turn of the century and put into mass production with the Ford Model A in 1927. Leaf springs haven’t changed all that much in the modern era. The overall function and design of the leaf spring haven’t changed, but they have been improved to be more durable and strong. The leaf spring’s characteristics and mode of operation, however, remain the same. But what are the benefits and drawbacks of leaf springs?
Leaf spring advantages
The leaf spring has a number of noteworthy benefits. The following are a few of the main benefits: The axle is held in place by the suspension, which is built in such a way as to serve as a linkage without the need for a separate linkage. The position of the rear axle reduces extra weight and expenses. A Panhard rod and traling arms are no longer required as a result. Leaf springs are the best choice for commercial vehicles since they sustain the chassis’ weight. The high rear moment center and large spring base allow for more effective control of the chassis roll. The roll inclinations will decrease if the springs are set more apart.
The disadvantages
Even though the modern leaf spring has several important benefits, there are a few drawbacks that you should be aware of. These are listed below: Although they aren’t always the simplest to install, there is a straightforward procedure to follow that greatly simplifies things. Because of the friction that exists between each leaf, the ride comfort isn’t as good. The springs have a tendency to droop and lose their shape over time. Uneven sag can change the vehicle’s gross weight, which may have a little impact on how it handles. The axle-to-mount angle may also alter as a result. Acceleration and braking torque can result in wind-up and vibration. Additionally, the wind-up may result in rear-end squat and nose-diving. It’s vital to weigh the benefits and drawbacks of any purchase before proceeding, particularly when it comes to vehicle performance.
Why choose leaf springs?
The basic structure of a leaf spring is made up of thick layers of metal, making them capable of supporting enormous vertical weights. They are ideal for commercial vans, pickup trucks, trailers, and trucks because they provide an enormous amount of support between the wheels, axles, and chassis of the vehicle, which is necessary in these situations.
