The invention discloses a double-wishbone front-suspension
system applied to driving of an inner rotor hub motor. The double-wishbone front-suspension
system comprises a steering
knuckle, an upper
control arm, a lower
control arm, a
shock absorber spherical hinge lower supporting arm, a spring
damper assembly, and the inner rotor hub motor. The steering
knuckle is provided with an upward extendingsupporting arm, the upper
control arm is hinged to the top end of the supporting arm to form a first
hinge point, and the lower control arm is hinged to the lower end of the steering
knuckle to forma second
hinge point. The
shock absorber spherical hinge lower supporting arm comprises a
hollow cylinder with a side opening in one side and a rectangular flat plate vertically placed with the hollowcylinder, wherein the extended end of the rectangular flat plate is connected with the middle part of the supporting arm through a ball head pin to form a third
hinge point. The upper end of the spring
damper assembly is supported on a vehicle body, and a cylinder
barrel at the lower part of the spring
damper assembly is fixed in the
hollow cylinder, the inner rotor hub motor is matched with thehollow cylinder of the steering knuckle, wherein the third hinge point is located on a connecting line between the first hinge point and the second hinge point. The double-wishbone front-suspension
system solves the problem of interference of the wheel hub motor on the arrangement of suspension components and various components during wheel steering and up and down movement.
