Said torsion bar spring (4) primarily constructed of a torsion spring bar is held on the door assembly part by a shaft part (14) which is connected to a load arm (17) such that it is prevented from turning. In addition, the torsion bar spring is supported against the door assembly part by a support arm (16) which is connected to said door assembly part. The catching device (8) assigned to the load arm (17) of the torsion spring bar is formed by at least two catching rollers (18) which are rotationally mounted on each bearing journal. In order to prevent the door stop from becoming noisy as a result of possible aspects of wear in the vicinity of the catching device (8), the invention provides that at least the catching rollers (18) are surface hardened in a middle area (19) which extends over a part of the height of said rollers.
Description
The present invention relates to a kind of torsion bar type door prop of arrangements for automotive doors, it can be fixed on the door assembly part by one, catch means on car door or the car door post and the torsion-bar spring that can be fixed on another door assembly part are formed, wherein, the whole torsion-bar spring that constitutes by the torsionspring bar by a bar partial fixing that is connected with the loading arm anti-rotation on the door assembly part and one therewith the support arm that connects of part be supported on this door assembly part, and here,, the catch means of the loading arm of torsionspring bar configuration constitutes for being rotatably installed in a lock-bit roller on the supporting neck respectively by at least two.
Though, in principle, the feature of this torsion bar type door prop is, the braking bed knife is to be fixed on another door assembly part with one and the catch means that has a lock-bit mark at least cooperates acquisition by be clamped in torsion-bar spring on door assembly part, car door or the car door post in a side, yet, known different forms of implementation has been arranged in this scope, exactly, not only have with body hinge irrelevant that use but also the door prop of structurally unifying with body hinge arranged.All this known torsion bar type door prop structures, no matter whether they are as irrespectively using with body hinge or using as the door prop of structurally unifying with body hinge, all exist this problem, that is, noise can take place after work a period of time strengthen.Because the torsion bar type door prop of this structural shape of being familiar with has the different single structures of many kinds, more the reason of morning or more late generation noise increasing also is different at work.
In the simplest torsion bar type door prop of here mentioning of this structural shape, catch means by one perpendicular to the body hinge axis orientation be fixed on door assembly part and sector be furnished with at least one lock-bit mark on the excircle of the concentric bending of its and body hinge axis is formed, and torsion-bar spring is made of the spring lever of a S or the bending of C shape, it is fixed on another door assembly part by an one crimp, and by its another crimp and catch means mating reaction.
In the simple torsion bar type door prop of this structural shape, enter into along with the crimp of the loading arm of formation of torsion-bar spring in the lock-bit mark that constitutes as draw-in groove of catch means, produce noise, this has interference when automobilism, can aware.Though, form by making the draw-in groove that constitutes the lock-bit mark smoothly can alleviate this extremely unwelcome noise, yet, must tolerate also that simultaneously the car door fixed point is uncertain.
For on the one hand in the location with keep car door to reach pinpoint accuracy aspect stopping, reduce the noise of torsion bar type door prop on the other hand simultaneously, in improved torsion bar type door prop structure types (US-PS 3,550 185), the lock-bit mark of catch means is made of the lock-bit roller that is provided with the peripheral type exterior feature at least in part.Therefore, compare with simple form of implementation, though reached the transition from the sliding friction to the rolling friction between at least one lock-bit mark of the loading arm of torsion-bar spring and catch means to a certain extent, and got rid of at least in part by lock-bit mark and the loading arm noise that causes that is slidingly matched and strengthened.For the loading arm that further reduces again by torsion-bar spring enters a caused noise increasing in lock-bit position, predetermined lock-bit roller is all made with plastic material, so that also can reach object sound insulation yet in addition.This relatively more bothersome measure can not generally be got rid of the noise that is brought at least and strengthen when the loading arm of torsion-bar spring cooperates with catch means.These measures solve in long-play when noise strengthens problem can only obtain dissatisfied result, and one of reason also is property easy to wear, particularly lock-bit roller certainly.Therefore, when adopting here the torsion bar type door prop of said this structure (DE-PS 32 29 766), not long ago transfer to constitute with the metal manufacturing again the lock-bit roller of lock-bit mark, yet be mounted in pairs or configuration now at every turn, the mode that adopts is that two lock-bit rollers that are provided with the peripheral type exterior feature at least in part constitute lock-bit marks jointly respectively.But Gou Zao catch means only can guarantee to guarantee effectively to reduce noise when resting on the lock-bit roller continuously on the whole angle of loading arm at car door opening that guarantees torsion-bar spring like this.Rest on so continuously for the loading arm that guarantees torsion-bar spring on the lock-bit roller of catch means, at first need necessarily to keep it to aim at mutually, in car door opening and closing movement process, the loading arm of torsion-bar spring can slide into from the peripheral type exterior feature of a lock-bit roller in the peripheral type exterior feature of adjacent lock-bit roller continuously, certainly, prerequisite is, the lock-bit roller can not can not relative reversing mutually occur at the closing of the door motion process at the car door opening motion process, that is to say that two adjacent lock-bit roller periphery complementary type exterior features must always keep identical two direction of rotation, the mutual aligned position of predesignating.Yet, because inevitably and the wear phenomenon that increases the weight of day by day that causes along with the time progress, mainly be on the lock-bit roller, even in this relatively more bothersome torsion bar type door prop structural shape, can not guarantee fully reliably whole long running time two adjacent supports roll necessary pressure and aim at mutually, consequence is, after the suitably long time of door prop operation, noise also can take place when adopting the torsion bar type door prop of this structural shape strengthen.
Therefore, task of the present invention is, improve the torsion bar type door prop of structural shape noted earlier, adopt simple means and while when torsion bar type door prop structural component is identical, avoid strengthening owing to the noise that possibility occurring wear phenomenon in the catch means scope causes.
According to the present invention, this task is basically by this solution, at least lock-bit roller and they only the lumbar region upper surface on the part that reaches its height quench.The lock-bit roller quenching with the region upper surface of torsion bar type spring-loaded arm contact, also weares and teares thereby prevent to occur wear phenomenon on lock-bit roller circumference at least.Therefore, guarantee that at first the lock-bit roller remains its periphery and is the cylinder configuration, and cooperates in the best way all the time with the loading arm of torsion bar type spring like this.On the other hand, it is dirty that the supporting that also makes the lock-bit roller owing to avoid wearing and tearing need not take special measure just can farthest prevent, thereby guarantee also can rotatablely move easily through lock-bit roller after the long-play, and got rid of equally in the lock-bit roller bearing and produce noise at door prop.Because can use cylinder lock-bit roller according to measure of the present invention, it also has the consistent lock-bit roller structure of advantage use to(for) multiple torsion bar type door prop modification structures, like this, also can reduce fabricating cost according to measure of the present invention.
Further set in the preferred form of implementation of the present invention, the lumbar region that the lock-bit roller surface quenches is configured to annular, and compares with all the other roll body diameters, and diameter is big.Here, lock-bit roller annular, hard-faced lumbar region has the cylinder outer circumference surface of a light face.
In addition, according to special feature of the present invention, the sub-fraction that each lock-bit roller axial height annular, hard-faced lumbar region is the whole height of lock-bit roller is preferably less than 1/3rd of the whole height of lock-bit roller.
In addition, combine with the quenching of lock-bit roller local surfaces, in favourable further structure of the present invention, also stipulate, the loading arm of torsion-bar spring has the cylinder outer circumference surface of a light face equally on its whole vertical section of cooperating with the lock-bit roller, and is hard-faced equally on this zone.
In addition, stipulate that in a preferred structure pattern catch means includes three and that settle with the circular orbit of body hinge axis decentraction along one, rotatablely respectively is installed to a lock-bit roller on the supporting neck according to torsion bar type door prop of the present invention.
In addition, the feature of a torsion bar type door prop that catch means designed according to this invention is housed and structurally unifies with body hinge is, torsion-bar spring is positioned on the hinge wing, catch means is installed on another hinge wing, the hinge wing that is carrying catch means is made of a plate bending part, and the lock-bit roller that constitutes catch means is along the marginal portion configuration perpendicular to the dogleg section of hinge axes that stretch with the hinge axes decentraction, the plate bending part.
