Hi, I am the person who received materials for flat springs from you a few years ago.
Thank you very much for that!
I am writing to ask you a few questions regarding the flat springs for automobiles. I hope you can help me.
1. For automobile flat springs, it is normal to use multiple springs of the same thickness and gradually shorter lengths. If one flat spring with thin ends is used, it will have the same strength and lighter weight, but it is hardly used in real life. Can you tell me the disadvantage of this method?
2. Please let us know if there are any precautions when using flat springs for automobiles in combination with flat springs of different thickness.
We do not produce laminated flat springs for automobiles in your question, so we do not know that it may be correct or not because our knowledge in this field is limited. However, in general, it is better to stack multiple flat springs/sheets so that the deflection can be made larger than with one sheet.
I think that one of the advantages of stacking multiple sheets is to disperse stress and improve durability. Also, note that when using flat springs with different thicknesses in combination, the load and stress applied to each leaf spring are different, so I think that it is necessary to calculate and evaluate the stress applied to each spring.
How thick (in mlllimeters) are the springs in a car, for example, an ordinary taxi? Also, does the thickness change for medium-sized taxis and large-sized taxis? How about trucks, buses, etc.? Thank you in advance for your reply.
Spring Newbie, thank you for posting!
The specifications of flat springs attached to vehicles differ depending on the vehicles, so we cannot provide you with a comprehensive specification of the springs…
We apologize for not being able to provide you with an answer… Even for large vehicles, not only leaf springs but also air springs are often used, so springs different from the flat springs that are often seen are often used.
