Advantage lies inits outstanding design flexibility, areasonable choice bythe Department ofguide bar contact point location and the length ofthe control arm, making the suspension has areasonable flow conditions. SUV models the design ofdouble wishbone suspension design, mapping method and the plane using the plane analytical method the suspension ofthe upper and lower arm ofthe size and spatial layout design, calculations also use double-shock matching device and the coil spring suspension system, Geometric alignment parameters toensure that the tire swing inavariety ofsuspension cases are inline with the requirements ofautomobile driving, repeated in various forms ounting toensure the best under the conditions of smoothness and operational stability.
