Embodiment Construction

[0029] The invention relates to a shaft (1), especially a drive shaft, for a vehicle, especially a trailer. The invention also relates to a rocker assembly ( 6 ) for such an axle and a vehicle equipped with the axle ( 1 ). Furthermore, the invention relates to a manufacturing method.

[0030] figure 1 An example of such a shaft ( 1 ) is shown, which is designed here, for example, as a non-braking transmission shaft. The shaft (1) has a shaft body (4) and a rocker assembly (6) supported thereon, which carries the hub (9) and the wheels (see Figures 15 to 18 ). Furthermore, the axle (1) has a suspension (5) for the rocker assembly (6) and is designed, for example, as a rubber spring axle.

[0031] In the embodiment shown, rocker assemblies ( 6 ) are present at both ends of the axle body ( 4 ). In a variant not shown, the shaft ( 1 ) can be designed as a separate shaft, on its two shortened shaft bodies ( 4 ), the rocker assembly ( 6 ) is supported on only one side in each ...

Abstract

The invention relates to a carrying axle (1) for trailers and a method for the production thereof. Said axle (1) comprises an axle body (4) having an outer supporting axle tube (10) in which a rocker arm assembly (6), which is bent once or several times, is introduced and which is produced as a metal, tubular stamped and bent single piece, and said rocker arm assembly is stamped from a platine (21) or a sheet metal strip (23) and is bent in order to form an angled tube (22).

Description

technical field [0001] The invention relates to a shaft and a manufacturing method with the features of the device and method main claims. Background technique [0002] Such a shaft is known from document US 6,588,778 B1. It is designed as a drive shaft for a trailer and has an axle body, axle suspension and rocker assembly. The rocker assembly is constructed in one piece and consists of an inner shaft tube and a rocker which has a different cross-sectional shape and is produced from a prefabricated one-piece tube by a hydroforming process. The inner axle tube is inserted into the outer axle tube connected to the trailer, wherein a rubber cord is inserted between them to form the axle suspension. A shaft stub is inserted into the free tube end of the repeatedly bent rocker. The previously known rocker assemblies require high and expensive structural outlay. [0003] Document FR 2 753 930 shows a similar rubber spring shaft (Gummifederachse) with a one-piece rocker assemb...
