Why do HR subframe connectors have (2) triangles as cross tubes?
Our patent pending subframes encompass the dual triangle configuration due to its inherent rigidity. The three points of contact of a triangle is the optimal design in tube chassis. The shape and dimensions of a triangle will not change much unless one of its three elements is damaged. Our products maximize this structural element in the design of our chassis systems to create the stiffest chassis possible with minimal bulk. In a complex structure, it is the design as a whole that determines stiffness. Manufacturing cross tubes using round material that mates to a round and normal (90 degree) surface with numerous angles requires multiple set-ups and machine processes. The flexural rigidity of the end product is the engineering driving force behind the patent pending dual-triangle system.
