This afrimto toe tortoer bsnëit that: the adhesive connection between the spring and too spring insert requires no additional process step in erdete to prepare the adhesive stmneetion, tossed the adhesive has been Inbodmted'betwçbhiiipi'pri^ aud the sprisif Insert «#4*φ&amp;£$ΜΜΙ is .pmed: to; lle spring, the assembly so Ionised of toe spring: mid the spring insdri; eah: be torthef processed to form a springwptem. tor example, m provide a Spring stritt Of a vehicle ChaSshi :ϊίό hardening of the adhesive at room tompomtorn can oeetsr in or during astolin wing momn ing proesssiosmldr completion of the spring system lor the vehicle chassis.

'she :##&amp; spriftg assert: Ort the spmg wito the adhesive eonnoction may preferably occur at the irrst lower Cpdmi'lte spring, pointing in toe direction Of the vehicle avlef since at this end she influence of contatomants OP the feeàhmg armssgemeot is toe greatest 1« particular,: the besting wtengesoeol may bo with a;spring plate especially to catch s&amp;ntosnd dost: contominnnls whicit anight have an abrasive eitect m, the spring if it is not integrally bonded to the spring Insert. The aibromentloned pencils of the adhesive connection between the spring insert and the spring may also, however, be used for the second upper end of the spring, pointing preferably in the dlrectloss of the spring dome. According to the invention, Ow spring insert comprises an oisstomer and is tlexihie in configuration, white the spring insert is designed to move along in the spring coil, in this way, the spring insert may consist of a shape-stable, yet elastically deformable plastic, and the spring characteristic of the spring is not indttenccd' Py the assembly of the spring Insert with the end-side spring coil. Thanks to toe moving of she spring insert!: along with the spring coil, toe ralisig movement of the spring sso longer ocessrs at too contact she with the spring insert: 0* evest wills toe spring pinte, and toe rolling nmvetnani occurs preferably between the spring insert and the sprmg plate. 1¼ ifrihf lösest májí be desipusilis the ipuuter of s ring méMmnű »VersitS8|l«^fat least 110¾ ptotorahly $f' m least WfW bad in particular öll up 1¾ SUP or «soso. ff fe angle Is less Utah Mt°, the spring; insert Is fashioned as a lathi of open stag* ssnii ihr so angle of ISO* it has the; '8fesp% for example.. of a halfnteon. ituhe angle by vkhich the spring Insert extends about a centre sxh h 560¾ tot example, It may be designed: 8S:® silt ring, Λ first cad region of -he spring insert vests against; the; ypring;|iisie here, and &amp; secosri end· negthe rif 01#· sgtitif: fngpri moves along with the spring coil of the spring.

Advantageously, the spring instat has an appro-tin·;««!·,· rectangular basic cross section: which isi la particular tortaed. consistently· ow: &amp;* mmh$(xÊtmâiîm:îKo.

Thanks so the rectangular basic erosy Section bf the· spring; Insert, the; latter can have a base; surface by which the spring Insert rolls along the bearing: sisite of the spring plate when; the spring: is oota|r8SS«d:, Aitorostwsiy, the basic: cross: section of the sgring: |β· indy also have a, variable1 eonftgtteion alostg: tbs ring“sbape4 :e|rentp|ei®ncei: atid tor axatngle the spring: briert: may bave: g: planar base surfen tsver tit»· strife ciretnatbrenee, by felehfe spring insert lies against the spring plate. The top side may1 have, for eásttöpió, tm sue ire ting depression with a pitch corresponding to the push of the spring; coll. In a spring suspension, and eonsetgtenriy upon movement of the spring: coll along: the spring plató, a compression of the spring insert may occur, m that no relative movement, especially m rolling moveutoni, would occur either between the spring coll and the spring Insert nr between the spring Insert arid the spring plate.

The hearing arrangement Is part of a suspension system of a spring strut of a vehicle chassis, in which the helical compression spring la configured, in particular, a shock absorber may bo led through the helical compression spring, ifeug arranpd connsntríeaÜy dr eccentrically to the axis pfrihatlon of ihc heiioai ctnuprgsskm spring, in particular, the spring plate may Ire brought into connection with the shock absorber, and the helical compression sprhtg may ho braced by the lower end side against the spring plate and by the upper side against, a corresponding mounting arrangement. According ip the Inveofes, a compressive prestress is Introduced into the spring, while the adhesive can be hurdeised under the action of the compressive prestes., This accomplishes a special: advantage, since by: virtue of the iifeeolftg öf the shhcsfe between site; spring; and too sprhtg insert rib lalagendencpeoeess: step Is raqnlmd ihr the httrilehlhg of the ;adhcsive:, and: the apsmlriags of the spring: and the spring insert may also be farther pttKiossed when the adhesive has already bean itufbduoed into the joint, but has not yet hsrileped- Bbweyely especially advantageously the hardening occurs: under the comnreasive gresfess: of the spring; In the Kusfebsiob system, so that a pressure between the parts belngdothed ss easily applied1 bf order to make: m adhesive conneotinn which cm be prestesed.

With the method, according to the Invention*·?* spfrbgj. especially tor a spring of a vehicle chassis, con he created, svherelo «^»dlus#?«iMnîroélbed '$&amp; spring and. the spring insert so that the connection of the spring msert to the spring conrprises; so adhesive connection. The special benefit oflhe method according in the invention Is accomplished In: that feiafienätg ci tire adhesive may occur tinder the applied Spring biasing, so that lha bardeamg of the adhesive requires no separate labrieationmp.

In particular, betöre the adhesive is arranged on the spring insert, that surface of the spring insert which is to be protight into epntacf Wih dteigiiesive may te;i0v8te4· Frdtehly, that: sflœ in Ihe cpetreiiM depression of the spring insert may be activated in which the spring coil of the spring iá gined. Alternatively or additionally, the surface of the spring cod may also be activated in order to achieve a better adhesion of the adhesive to the surface of vite spring coil. Preferably, the activation snay occur at room temperature, so that no means need to be provided lor homing the adhesive cotmeeiionafe it has been: made. fhc sprittg of the bearing arrangement la destmted as a helical compression spring and Is presiressed avisiby with a compressive presness in order 10 form a spring strut of a vehicle chassis, svherela the adhesive is hardened under site action of rite compressive prestress,
