Synthesis of a Rear Wheel Suspension Mechanism With Pure Rectilinear Motion

摘要: This paper focuses on the synthesis of an independent suspension that can guide wheel to track a straight line when moving up (jounce) and down (rebound). With displacement subgroups, it first synthesizes rigid body guidance mechanism verifies result through screw theory. To simplify optimize loads each kinematic chain knuckle, investigates static equations ultimately symmetric redundant-constraint structure, which could not only eliminate shambling shocks induced by jumping wheels but also decrease abrasion tires. Theoretically, one pair noncoplanar chains is necessary realize guidance. However, second particularly utilized improve load status links. Because redundant constraints structures, whole weight be significantly reduced compared with initial one. ADAMS simulations set real parameters indicate rear proposed in this follow rectilinear locus during jounce rebound. Therefore, kind ride handling properties advanced vehicles.
