With the vehicle axis system is benchmark, wherein A type frame, left trailing arm and right trailing arm all with the xoy plane parallel, middle intermediate rod with the back intermediate rod parallel with the y axle.
Described A type frame, left trailing arm and right trailing arm are the box section structure.
Intermediate rod is the straight tubular propelling rod with the back intermediate rod in described.
The beneficial effect of the utility model is:
One of which, this vertical force transfer element are not only simple in structure, compact in design but also can effectively reduce the movement interference between each member of balance suspension; Improve the service life of balance suspension; Reduce the use and maintenance expense cost, be suitable as vertical force transfer element of the middle rear suspension of engineering truck.
Two, adopt the combination of A type frame, left and right sides 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 is simple in structure, 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 the xoy plane parallel, in, the back intermediate rod parallel with the y axle.This arrangement form can effectively reduce each mechanism kinematic interferes, and prolongs the service life of balance suspension.
