DongfengDANA Star Products Axle IFS75
This product is the first single suspension bridge developed by Dongfeng Dana. The lightweight structure design and steering ladder matching optimization greatly reduce the quality under the spring and make the whole vehicle run more smoothly.
1. Applicable model: 11 -12 m large road bus.
2. Product advantage
a. Lightweight: using lightweight structure design and low density material molding, lighter weight;
b. comfort: lower quality under spring, driving comfort replacement, using imported shock absorber and airbag, optimize rubber ball hinge stiffness, through characteristic curve verification, real suspension stiffness, damping more reasonable matching, vehicle ride comfort;
c.safe and reliable: using integral upper and lower arms, suspension k&c characteristic simulation optimization, the first K&C bench verification in China. Product is reliable. Optimizing the position of breakpoint ensures that the Ackermann deviation of the rotation angle in the whole region is smaller, the steering is more accurate, and the driving at high speed is safer. The four-wheel positioning parameters of suspension are more reasonable, and the control stability of the whole vehicle is better.
