Description
Bisher bekannte Pflaster bestehen aus 2 oder mehreren Lagen von gummiertem Cordgewebe, welche auf einer oder beiden Seiten mit einer dünnen unvulkanisierten Gummischicht abgedeckt sind. Diese Pflaster sind so aufgebaut, dass die einzelnen Cordlagen kreuzweise und symetrisch übereinander gelegt sind, (Figur 1) wobei in der Mitte des Pflasters eine quadratische Zone von sich kre # den Cordfäden entsteht. Die Dicke dieser Zone ist je nach Lagenzahl ein Vielfaches der Cordfadenstärke. An den Enden ist dagegen die Stärke nur gleich einer Cordlage.Previously known plasters consist of 2 or more layers of rubberized Cord fabric, which on one or both sides with a thin unvulcanized Rubber layer are covered. These plasters are constructed so that the individual Cord layers are placed crosswise and symmetrically on top of each other, (Figure 1) where in In the middle of the plaster a square zone of twisted cords is created. The thickness of this zone is, depending on the number of layers, a multiple of the cord strength. At the ends, on the other hand, the thickness is only equal to one cord layer.
Diese zwansläufige unterschiedlichen Stärke des Pflasters veruracht Spannungen bei der Walkarbeit des Autoreifens. Besonders in der Symetrieaches A B (Figur 1) ist der Übergang von der dicken Mittelzone nach dem dünnen Band des Pflasters sehr steil.This inevitably causes different thickness of the plaster Tensions in flexing the car tire. Especially in the symmetry axis A B (Figure 1) is the transition from the thick central zone to the thin band of the Very steep pavement.
Loslösen und Einreißen des einvulkanisierten Pflasters an dieser Stelle ist beobachtet worden.Detachment and tearing of the vulcanized plaster at this point has been observed.
Um diese kritische Stelle zu vermeiden, wird gemöss der Neuerung vorgeschlagen, die einzelnen Cordlagen kreuzweise, aber asymetrisch anzuordnen (Figur 2). Buch bei dieser Anordnung entsteht eine quadratische Zone von sich kreuzenden Cordfäden, der Übergang von der maximalen Stärke zum Rand in der Symetrieachse C D ist aber wesentlich flacher und verursacht weniger Spannungen.In order to avoid this critical point, it is proposed according to the innovation, to arrange the individual cord layers crosswise but asymmetrically (Figure 2). a book this arrangement creates a square zone of intersecting cords, however, the transition from the maximum strength to the edge in the axis of symmetry C D is much flatter and causes less tension.
Hinzu kommt, dass weniger Cordgewebe benötigt wird, um den gleioben Reparat4ureffekt zu erzielen. Das Pflaster wird leichter, die Reparaturzone zudem weniger versteift. Dies ergibt weniger Unwucht und geringere Erwärmung beim Durchwalken des Reifens.In addition, less cord fabric is required to achieve the glide To achieve repair effect. The plaster becomes lighter, as does the repair zone less stiffened. This results in less imbalance and less heating during flexing of the tire.
