The improvement of technique scheme is: described middle part bindiny mechanism also comprises some middle suspensions, described middle suspension comprises front bearing, rear support, the 3rd torsion bar and the 3rd fixation assembly, described 3rd torsion bar to be arranged between described front bearing and described 3rd fixation assembly and hinged with the two, the leaf spring of described 3rd fixation assembly and described middle suspension is affixed, and described front bearing and described rear support are provided with the equilibrium arm assembly for being connected with each leaf spring.
The improvement of technique scheme is: the setting height(from bottom) of described first bearing and described second bearing is all lower than the setting height(from bottom) of described front bearing, rear support and described support pedestal, and diff-H is 80mm.
The improvement of technique scheme is: described middle part bindiny mechanism with the center line of described longeron in the middle part of symmetric line is distributed in described longeron.
The beneficial effect of the utility model employing technique scheme is: in the utility model design process, the bearing setting height(from bottom) of forward and backward suspension is all reduced 80mm compared with the support pedestal of middle part bindiny mechanism, front bearing and rear support height, longeron above suspension adopts two channel variable-sections, when ensureing that trailer suspension normally uses, chassis member height above fore suspension and rear suspension has increased 80mm, adds trailer longitudinal beam intensity.
The principle of work of trailer suspension of the present utility model is with conventional suspension, while possessing conventional suspension function, by reducing the measures such as the mast height of the fore suspension and rear suspension in suspension, both ensure that equilibrium arm pendulum angle and axletree jerk value, longeron intensity is got back reinforcement.
The utility model can use on all kinds of trailer, improves the in-use performance of trailer suspension.Trailer structure is strengthened, its distortion can be prevented, damage, enhance the reliability of service of trailer, safety.
