Be benchmark with vehicle coordinate, wherein A type frame, left trailing arm and right trailing arm all with xoy plane parallel, middle intermediate rod is parallel with y axle with rear intermediate rod.
Described A type frame, left trailing arm and right trailing arm are box section structure.
Described middle intermediate rod and rear intermediate rod are straight tubular propelling rod.
The invention has the beneficial effects as follows:
Not only simple in structure, compact in design but also can effectively reduce the movement interference between the each member of balance suspension of one, this longitudinal force transfer element, improve the service life of balance suspension, reduce use and maintenance expense cost, be suitable as longitudinal force transfer element of the middle rear suspension of engineering truck.
Two, adopt the combination of A type frame, left and right trailing arm and intermediate rod, make full use of the advantage of A type posture and two kinds of array modes of single trailing arm type, make that balance suspension structure is simple, rationally distributed, productive costs is low, use and maintenance cost is few.
Three, in vehicle axis system, A type frame, left trailing arm, right trailing arm all with xoy plane parallel, in, rear intermediate rod is parallel with y axle.This arrangement form can effectively reduce each mechanism kinematic interferes, and extends the service life of balance suspension.
