Abstract

Testrolle (2) mit einer stufenlos höhenverstellbaren Stossleiste zur dynamischen Belastung von Fahrzeugrädern, dadurch gekennzeichnet, dass die Stossleiste als radial ausschwenkbare Klappe (1) ausgebildet ist, deren Verstellung durch ein Gestänge (3) erfolgt, das durch eine Schiebehülse (4) auf der Welle (5) achsial betätigt wird.Test roller (2) with an infinitely height-adjustable bumper strip for dynamic loading of vehicle wheels, characterized in that the bumper strip is designed as a radially pivotable flap (1), the adjustment of which is carried out by a rod (3) which is supported by a sliding sleeve (4) on the Shaft (5) is actuated axially.

Description

Die Erfindung betrifft eine Vorrichtung zur stufenlosen Höhenverstellung einer Stossleiste auf dem Mantel einer Testrolle während des Testlaufes.The invention relates to a device for stepless height adjustment of a bumper on the jacket of a test roll during the test run.

Rollenprüfsrände belasten die Räder der Testfahrzeuge durch Fahrbahnimpulse, deren Energie durch die Drehzahl der Testrolle und durch die Höhe der Stossleiste bestimmt wird.Roller test beds load the wheels of the test vehicles by road impulses whose energy is determined by the speed of the test roller and the height of the bumper.

Bekannt sind Testrollen mit Stossleisten, die in Achsrichtung gleich bleibend hoch sind oder kontinuierlich, bzw. gestuft ansteigen. Bei ansteigenden Stossleisten wird die wirksame Höhe der Stossleiste durch seitliches Verfahren des Fahrzeuges auf der Testrolle angesteuert.Are known test rolls with bumpers that are consistently high in the axial direction or increase continuously, or stepped. With rising bumpers the effective height of the bumper is controlled by lateral movement of the vehicle on the test roller.

Bekannt sind auch Testrollen mit Stossleisten, deren Höhe am Mantel durch achsial bewegte Schiebeelemente verändert wird.Also known are test rollers with bumpers whose height is changed on the jacket by axially moving sliding elements.

Es ist Aufgabe der Erfindung die präzise stufenlose Höhenverstellung einer Stossleiste während des Testlaufes zu ermöglichen, ohne dass Fliehkräfte oder Stossbelastungen die wirksame Höhe der Stossleiste nachteilig beeinflussen.It is an object of the invention to allow precisely stepless height adjustment of a bumper during the test run without centrifugal forces or shock loads affect the effective height of the bumper adversely.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die Stossleiste als ausschwenkbare Klappe (1) am Mantel der Testrolle (2) ausgebildet ist und durch ein Gestänge (3) bewegt wird, dessen Prinzip als Regenschirmspreizung bekannt ist, und dessen Bewegung durch eine Schiebehülse (4) auf der Welle (5) ermöglicht wird.This object is achieved according to the invention in that the bumper as a swing flap ( 1 ) on the jacket of the test roll ( 2 ) is formed and by a linkage ( 3 ), whose principle is known as umbrella spread, and whose movement through a sliding sleeve ( 4 ) on the shaft ( 5 ).

1 zeigt eine Testrolle mit eingeschwenkter Stossleisten-Klappe. 2 zeigt diese Testrolle mit ausgeschwenkter Stossleisten-Klappe. 1 shows a test roll with pivoted-in bumper flap. 2 shows this test role with swung-out flap door.
