Definitions
- the invention relates to a torsion bar door arrester for motor vehicle doors consisting of a latching device which can be attached to one door arrangement part, door or door frame, and a torsion bar spring which can be attached to the other door arrangement part, the torsion bar spring formed overall from a torsion spring bar via a shaft part connected in a rotationally secure manner to a loading arm is supported on the door arrangement part and a support arm connected to it is supported against the door arrangement part and the latching device assigned to the loading arm of the torsion spring bar is formed by at least two latching rollers rotatably mounted on a respective bearing pin.
- Such torsion bar door arrester are basically characterized in that the braking and holding force is applied by the interaction of a torsion bar spring clamped on one side on a door arrangement part, door or door pillar with a latching device fixedly attached to the other door arrangement part and having at least one detent mark, but are within
- This frame is known per se in the most varied of embodiments, both as a door divider that can be used independently of the door hinge and structurally combined with the door hinge.
- All known types of torsion bar door arrester regardless of whether they are used as independent of the door hinges or as structurally combined with the door hinges, is subject to the problem that noise may occur after a period of operation.
- the causes of a noise development which sooner or later arises during operation are also different. 2 -
- the latching device consists of an attached to a door arrangement part aligned transversely to the door hinge axis and provided with at least one detent segment on its outer circumference curved concentrically to the door hinge axis, while the torsion bar spring by an S or C -shaped spring rod is formed, which is clamped via its one bend on the other door arrangement part and interacts with the locking device via its other bend.
- the drop in the torsion bar spring forming a load arm into the latching mark of the latching device which is designed as a latching recess, results in a development of noise, which becomes noticeable in the operation of the vehicle.
- a transition from a sliding to a rolling friction between the loading arm of the torsion bar spring and the at least one detent mark of the detent device was achieved to a certain extent and the noise development resulting from the sliding interaction of the detent mark and load arm was at least partially eliminated.
- the locking rollers are formed entirely of a plastic material so as to achieve structure-borne noise insulation. Even such, relatively complex measures have at least not brought about any general elimination of the problem of noise development when the load arm of the torsion bar spring interacts with the latching device.
- One of the reasons why these measures have only led to unsatisfactory results in solving the problem of noise in long-term operation is surely also the susceptibility to wear, especially the locking rollers.
- the invention is therefore based on the object to improve torsion bar lock of the type mentioned in such a way that noise is avoided due to possible signs of wear in the area of the locking device with simple means and at the same time standardizing the components of a torsion bar lock.
- This object is essentially achieved in that at least the locking rollers and these are surface hardened only in a belt area extending over part of their height.
- the surface hardening of the locking rollers at least in an area that comes into contact with the load arm of the torsion bar spring prevents the appearance of wear on the circumference of the locking rollers and hand in hand, thus also preventing the occurrence of abrasion.
- This first of all ensures that the locking rollers always maintain a cylindrical shape on their peripheral surface and therefore always interact in an optimal manner with the loading arm of the torsion bar spring.
- the avoidance of abrasion also results in the bearings of the locking rollers being also without special ones
- Measures are largely kept free of dirt, so that smooth rotation of the locking rollers over a long period of operation of the door arrester is guaranteed and the occurrence of noise in the locking roller bearing is also excluded. Since the measure according to the invention enables the use of cylindrical locking rollers, 5 -
- the surface-hardened belt area of the locking rollers is ring-shaped and has a larger diameter than the diameter of the rest of the roller body, the ring-shaped, surface-hardened belt area of the locking rollers also having a smooth, cylindrical outer peripheral surface.
- the axial height of the ring-shaped, surface-hardened belt area of each locking roller is only a fraction and preferably less than a third of the total height of the locking roller.
- the load arm of the torsion bar spring also has a smooth, flat outer circumferential surface over its length section interacting with the locking rollers and also in this area is surface hardened.
- the latching device comprises three latching rollers which are arranged along a circular path which is not concentric with the hinge axis of the door and are each rotatably mounted on a journal. 6 -
- a torsion bar spring door arrester equipped with a latching device designed according to the invention and structurally combined with a door hinge is expediently further characterized in that the torsion bar spring is arranged on one hinge wing and the latching device on the other hinge wing, the hinge wing carrying the latching device being formed by a sheet metal folding part and the latching rollers forming the latching device are arranged along an edge region of an angled portion of the sheet metal fitting that is offset transversely to the hinge axis and does not run concentrically with the hinge axis.
- Figure 1 is a plan view of a torsion bar door lock structurally combined with a door hinge
- FIG. 2 shows a side view of the torsion bar door arrester according to FIG. 1, structurally combined with a door hinge;
- the assembly shown in the drawing consisting of a hinge and a torsion bar lock, for detachable motor vehicle doors, consists of a hinge with two hinge wings 2 and 3 pivotally connected to one another by means of a hinge pin 1, one of which 2 remains on the door body (not shown in the drawing) and whose other 3 is releasably attachable to the door pillar, also not shown in the drawing, and a torsion bar door lock 4.
- the hinge wing 3 releasably attachable to the door pillar, is formed from a U-shaped sheet metal material blank, with the upper leg 5 directed transversely to the hinge axis 5 U shape
- a locking device 8 of the door arrester 4 formed from alternately successive projections 6 and depressions 7 is formed and a pin-shaped projection is formed on the lower leg 9 of the U-shape, oriented transversely to the hinge axis, in the same direction as an extension 10 of the hinge pin 1 directed beyond the hinge height.
- the hinge wing 2 has an approximately L-shaped cross-sectional shape and is arranged engaging in the hinge wing 3, whereby it is rotatably connected to the hinge wing 3 by means of its one profile leg via the hinge pin 1 and is fastened to the door via its other profile leg 13.
- the torsion bar door fixed studio 4 which is connected to the hinge in terms of construction, has an S-shaped torsion bar spring, which is supported above its sheep part 14 with the interposition of a bearing shell 15 on the engaging hinge wing 2 and is supported against it by a support arm 16, the area of which supports the loading arm 17 the two hinge wings 2 and 3 protrude upwards.
- the loading arm 17 of the torsion bar spring interacts with the three locking positions 8 for the door, which are formed on one leg 5 of the U-shape of the hinge wing 3 and are formed from mutually successively arranged projections 6 and depressions 7.
- the latching means of the latching device 8, which cooperate with the loading arm 17 of the door arrester, are formed here by three latching rollers 18 of uniform design, each of the latching rollers 18 being mounted on a respective journal of the projections 6 of the latching device 8 via a journal 25 about a vertical axis .
- the three locking rollers 18 of the locking device 8, each of which is rotatably mounted on a bearing pin 25, are arranged along a circular path that is not concentric with the hinge axis of the door.
- the locking rollers 18 are surface-hardened only in a belt region 19 that extends over part of their height.
- the belt region 19 of the locking rollers 18 is, as can be seen in particular from the illustration in FIG. 2, is ring-shaped and has a larger diameter than the diameter of the remaining roller body 18, wherein, as can be seen in particular from the illustration in FIG. 2, the annular one , surface-hardened belt region 19 of the locking rollers also has a smooth cylindrical outer peripheral surface.
- the axial height of the ring-shaped, surface-hardened belt region 19 of each locking roller 18 is only a fraction and preferably less than a third of the total height of the locking roller 18.
- the load arm 17 of the torsion bar spring also has a smooth outer cylindrical circumferential surface via its length section 20 which interacts with the locking rollers 18 and in particular the surface-hardened belt region 19 of each locking roller 18 Area is also surface hardened.
