Abstract

The utility model discloses a kind of trailing arm cross beam type independent suspension, including two trailing arms, crossbeam, two helical springs, two hydraulic damper.The torsion beam of the utility model and prior art takes the mode being fixedly connected different with trailing arm, by changing the connected mode of crossbeam and trailing arm, the trailing wheel of automobile two is set independently to move up and down, and non-interference, the effective semi-independent suspension comfortableness of torsion beam type that compensate for is poor, the shortcoming of maneuverability difference.

Description

Trailing arm cross beam type independent suspension

Technical field

The utility model is a kind of kart suspension, is in particular a kind of rear wheel independent suspension of kart.

Background technology

The rear-mounted of many kart is hung using trailing arm torsion girder-like at present.Trailing arm torsion girder-like dependent is hung The suspension frame structure of trailing wheel design is aimed at, its composition is very simple：Wheel and vehicle body are realized with sturdy vertically shaking trailing arm Or the rigid connection between vehicle frame, then soft connection is realized with hydraulic damper and helical spring, to reach shock-absorbing and support The purpose of vehicle body, and cylindrical or square torsion crossbeam is connected to left and right wheelses.Due to the whole big portion of suspension system only one of which Part is constituted, therefore compared to complicated double yokes, multi link etc., structure is simply too much.It is welded into the suspension integral installation of H types On vehicle body, rocking arm and vehicle body only have two tie points, so assemble up simply, and cost is low.From the point of view of its construction, by In left and right, trailing arm is connected by crossbeam, therefore the suspended structure also maintains the characteristic of integral bridge type suspension, connects left and right trailing arm Crossbeam it is rotatable in junction, this just allows left and right wheelses to be operated respectively in a small range without interfering with each other to a certain extent But it is still too poor that this small range rotates comfortableness.In the design process, if the difference of installation site of the crossbeam on trailing arm, Its performance difference showed also can be obvious：Crossbeam is arranged close to trailing arm close to wheel center position, then comfortableness It can have a greatly reduced quality.Simultaneously during body sway, because of the distortion of torsion beam axle, making the inclination angle of wheel can change, influence manipulation Property.

The content of the invention

The purpose of this utility model is two trailing wheels is independently moved up and down without phase there is provided one kind for above-mentioned deficiency The independent suspension mutually disturbed.Trailing arm cross beam type independent suspension, including two trailing arms, the crossbeam with pivot, two helical springs, two liquid Damper composition is pressed, crossbeam is flexibly connected with trailing arm by pivot, pivot holder, so as to realize that two trailing wheels independently move up and down but It will not interfere, it is characterized in that trailing arm uses movable connection method with crossbeam.

Realizing the technical scheme of the utility model purpose is：

Trailing arm cross beam type independent suspension system is by left and right trailing arm, crossbeam, left-and-right spiral spring, left and right hydraulic damper group Into.Crossbeam two ends are respectively equipped with a pivot, are flexibly connected by pivot, trailing arm bearing with two trailing arms, into H-shaped (accompanying drawing 1).On trailing arm End is connected by pivot, pivot holder and car body.Trailing arm lower end passes through the soft connection of helical spring, hydraulic damper and car body. The suspension substituted for the torsion beam of trailing arm torsion girder-like independent suspension with the crossbeam of two ends pivotally, and crossbeam passes through pivot and peace Pivot holder on trailing arm is flexibly connected (accompanying drawing 2).Change torsion beam and trailing arm is fixedly connected with mode.So as to realize Two trailing wheels are completely independent up and down motion, will not interfere with each other (accompanying drawing 3).The utilization of such a structure, when automobile is excessively curved, one side When trailing wheel moves up and down, wheel center line is (accompanying drawing 3) perpendicular to the ground always, improves the handling of automobile.And the crossbeam It is very flexible in the link position of trailing arm, it can be arranged on except other optional positions near trailing arm pivot termination, without Foregoing, torsion beam installs the limitation that can be impacted to comfortableness close to wheel center point.

The profile, structure and torsion beam type that above design feature can be seen that trailing arm cross beam type independent suspension are semi-independent outstanding Hang with a little similar.But force way, suspension property, the suspension behavior of suspension have to move up and down completely between difference, automobile two-wheeled It is independent.Both the advantage of the semi-independent suspension of trailing arm torsion beam type had been inherited, the semi-independent suspension of trailing arm torsion beam type has been also overcomed comfortable Property it is poor, maneuverability difference shortcoming.Because the utility model profile, structure are similar with the suspension of torsion beam type, so existing not changing In the case of having the car body using torsion beam type IRS Independent Rear Suspension, trailing arm cross beam type independent suspension is directly applied.Indulge simultaneously These advantages that arm cross beam type independent suspension system has are that other a variety of suspension can not compare, so can also replace Change other independent suspension systems.

The crossbeam of trailing arm cross beam type independent suspension and the tie point of trailing arm can be arranged on appointing in addition to trailing arm hinge simultaneously Meaning position, accordingly it is also possible to voluntarily produce crossbeam by each vehicle size, the semi-independent suspension of torsion girder-like to various vehicles is carried out Transformation.

The utility model has that simple in construction, bearing capacity is big, lightweight, occupied little space, comfortableness is good, handling good etc. Feature.Promote and practical value, can be economized on resources after popularization with saving fuel oil consumption rate with good, reduce kart Production cost.

Embodiment

Exemplified by being transformed with the utility model trailing arm torsion beam, its torsion beam is removed, in left and right, trailing arm original is reversed Beam weld, it is each that a pivot holder is installed, two trailing arms are flexibly connected into H-shaped with the crossbeam of termination pivotally.Trailing arm upper end It is connected with car body, lower end passes through the soft connection of helical spring, hydraulic damper and car body.Simply and easily realize rear left and right car The self-movement up and down of wheel.The crossbeam of trailing arm cross beam type independent suspension and the tie point of trailing arm can be arranged on except trailing arm pivot simultaneously Optional position outside knob, accordingly it is also possible to voluntarily produce trailing arm cross beam type independent suspension by each vehicle size, implements innovation The semi-independent suspension of the torsion girder-like of various vehicles.
