Abstract
The utility model relates to a vehicle suspension and especially relates to a left-and-right through type energy storage suspension. According to the utility model, the upper end of a left wheel vibration isolator and the lower end of the left wheel vibration isolator are hinged to the left end of a cross rod coaxially; the upper end of a right wheel vibration isolator and the lower end of the right wheel vibration isolator are hinged to the right end of the cross rod coaxially; the cross rod is hinged to the middle part of a suspension cross beam and can rotate around a hinge axis in the middle. Static load of a vehicle body are all act on the left wheel vibration isolator and the right wheel vibration isolator through sharing the cross beam by a left suspension and a right suspension, so that a technical defect that inerters are easy to be punctured under effect of vehicle load is made up. Low frequency peak values of vehicle body vertical acceleration are restrained through a vehicle body vibration isolator. High frequency peak values of wheel dynamic load are restrained through the wheel vibration isolators. Stress of the left suspension and stress of the right suspension condition each other through sharing the cross rod by the left suspension and the right suspension, so that inclination of a vehicle body can be reduced and operation stability of automobile is thereby improved. Therefore, aims of improving riding comfort and enhancing driving safety are achieved at the same time.

Accompanying drawing explanation
Fig. 1 is the through energy accumulation hanger structural representation in left and right;
In figure, the right wheel vibration isolator of the left vehicle body vibration isolator of 1-crossbeam 2-left swing arm 3-left wheel vibration isolator 4-5-fixed link 6-cross bar 7-vehicle body 8-right vehicle body vibration isolator 9-10-right swing arm 11-spring 12-damper A 13-is used to container 14-damper B.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The utility model comprises crossbeam 1, cross bar 6, left swing arm 2, left wheel vibration isolator 3, left vehicle body vibration isolator 4, right swing arm 10, right wheel vibration isolator 9 and right vehicle body vibration isolator 8.
Crossbeam 1 is connected by two fixed links 5 are symmetrical with vehicle body 7, and cross bar 6 is articulated with the middle part of crossbeam 1, can be around middle part hinge axis.
Coaxial cross bar 6 left ends that are articulated with in left wheel vibration isolator 3 upper ends and left vehicle body vibration isolator 4 lower ends, the coaxial right-hand member that is articulated with cross bar 6 in right wheel vibration isolator 9 upper ends and right vehicle body vibration isolator 8 lower ends, cross bar 6 is level when balance position;
Left wheel vibration isolator 3 is composed in parallel by damper A12 and spring 1, and the lower end of left wheel vibration isolator 3 is articulated with the outer fix of left swing arm 2; Left wheel is hinged by left swing arm 2 and crossbeam 1 left end; Right wheel vibration isolator 9 is composed in parallel by damper A12 and spring 11, and the lower end of right wheel vibration isolator 9 is articulated with the outer fix of right swing arm 10; Right wheel is hinged by right swing arm 2 and crossbeam 1 right-hand member;
Left vehicle body vibration isolator 4 is by damper B14 and be used to container 13 and compose in parallel, and left vehicle body vibration isolator 4 upper ends and vehicle body are hinged, right vehicle body vibration isolator 8 by damper B14 be used to container 13 and compose in parallel, right vehicle body vibration isolator 8 upper ends and vehicle body are hinged.
Below in conjunction with accompanying drawing, the utility model specific implementation process is described further.
As shown in Figure 1, the shock and vibration that caused by Uneven road make the relative vehicle body up-and-down movement of left swing arm 2 make left wheel vibration isolator 3 through tire, left vehicle body vibration isolator 4 is started working and is passed through hinge axis drive cross bar 6 rotations between them, and right wheel vibration isolator 9 and right vehicle body vibration isolator 8 are started working; HFS in the shock and vibration that caused by Uneven road is by 3 decay of left wheel vibration isolator, low frequency part is cushioned and decay by left vehicle body vibration isolator 4 decay the shock and vibration that road pavement injustice causes within the scope of full frequency-domain, and owing to making right wheel vibration isolator 9 and right vehicle body vibration isolator 8 add work to accelerate vibration damping speed and by cross bar, left suspension has been applied to counter-force to have hindered left suspension relative motion under cross bar 6 drives, reduced body roll; When in like manner, shock and vibration are through right wheel, also can be decayed successively.
For traditional suspension, adopt soft spring can improve the travelling comfort of vehicle, yet but worsened the driving safety of vehicle, and adopt hard spring can improve the driving safety of vehicle, yet but worsened the travelling comfort of vehicle, the traditional suspension therefore being composed in parallel by spring and damper is difficult to take into account travelling comfort and the driving safety of vehicle; The form that the utility model adopts wheel spacer to connect with vehicle body vibration isolator, the high frequency peaks that suppresses tire live load with wheel vibration isolator, the low frequency peak value that suppresses vehicle body acceleration with vehicle body vibration isolator, the low frequency peak value that also can suppress the moving stroke of tire live load and suspension simultaneously, therefore the utility model has reached the object of taking into account vehicle riding comfort and driving safety, makes the overall performance of suspension obtain significantly lifting.
The mode that the utility model adopts left and right suspension to connect, has reduced vehicle roll, has improved vehicle handling stability; Wheel vibration isolator adopts the form of damper and spring parallel connection, with spring, carrys out the whole statics weight of bearing vehicle body, has overcome and has been used to the technical disadvantages that container easily " is punctured " under vehicle body load.
