FOUR BAR LINKAGE AND AIR SPRING SUSPENSION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240034115 titled 'FOUR BAR LINKAGE AND AIR SPRING SUSPENSION SYSTEM

Simplified Explanation

The abstract describes a suspension assembly for a commercial vehicle that includes various linkages and an air spring. The first linkage is pivotally coupled to a structural member of the vehicle's frame, while the air spring is coupled to both the frame and the second end of the first linkage. This allows the air spring to drive the first linkage to pivot about its first end relative to the structural member. The carriage is pivotally coupled to the first linkage at a position between its first and second ends, and the second linkage is pivotally coupled to the structural member at its first end and to the carriage at its second end. Together, the structural member, first linkage, second linkage, and carriage form a four-bar linkage.

  • The patent application describes a suspension assembly for commercial vehicles.
  • The assembly includes linkages and an air spring.
  • The first linkage is pivotally coupled to a structural member of the vehicle's frame.
  • The air spring is coupled to the frame and the second end of the first linkage.
  • The air spring drives the first linkage to pivot about its first end.
  • The carriage is pivotally coupled to the first linkage at a position between its first and second ends.
  • The second linkage is pivotally coupled to the structural member at its first end and to the carriage at its second end.
  • The combination of these components forms a four-bar linkage.

Potential Applications:

  • Commercial vehicles, such as trucks and buses, could benefit from this suspension assembly.
  • It could improve the ride quality and stability of the vehicle, especially when carrying heavy loads.
  • The assembly could be used in various types of suspension systems, including independent suspension setups.

Problems Solved:

  • The suspension assembly addresses the need for a robust and efficient suspension system for commercial vehicles.
  • It provides improved control and stability, reducing vibrations and enhancing overall ride comfort.
  • The four-bar linkage design allows for better weight distribution and load management.

Benefits:

  • Enhanced ride quality and comfort for drivers and passengers.
  • Improved stability and control, especially during cornering and braking.
  • Increased durability and longevity of the suspension system.
  • Better weight distribution and load management capabilities.


Original Abstract Submitted

a suspension assembly for a commercial vehicle includes a first linkage, an air spring, a carriage, and a second linkage. the first linkage is pivotally coupled at a first end with a structural member of a frame. the structural member extends downwards from the frame. the air spring is coupled with the frame and a second end of the first linkage. the air spring drives the first linkage to pivot about the first end relative to the structural member. the carriage is pivotally coupled with the first linkage at a position between the first end and the second end of the first linkage. the second linkage is pivotally coupled at a first end with the structural member, and pivotally coupled with the carriage at a second end. the structural member, the first linkage, the second linkage, and the carriage define a four-bar linkage.
