Embodiment Construction

[0021] figure 1 A motor vehicle 1 according to one embodiment of the invention is shown schematically. The vehicle exemplified here is a heavy vehicle in the form of a truck. The vehicle has a powered rear axle X connected to the traction rear wheels and equipped with a configuration for rear axle drum brakes in the form of a carrier structure. In alternative embodiments, the invention may also be used on non-traction, non-steering wheels.

[0022] Figure 2a-2b are different schematic perspective views of a part of a rear axle X with a part of a drum brake comprising a carrier structure for a drum brake of a motor vehicle according to the invention; and Figure 3a -b is Figure 2a - Different schematic side views of the carrier structure in b with the brake cylinder 10 and the eccentric shaft 20 .

[0023] The carrier structure is configured to fasten the eccentric shaft 20 of the drum brake and fasten the brake cylinder 10 of the drum brake in a journal-fitting manner. ...

Abstract

The invention relates to the construction of a drum brake for a motor vehicle in the form of a carrier structure. The carrier (30) for the eccentric shaft (20) is equipped with a separate mount (50) for the brake cylinder (10). The use of a carrier (30) for the eccentric shaft and a separate mount (50) for the brake cylinder (10) allows the fastener to be separated into separate parts, thereby improving the accessibility of the assembly and making it possible to Level pre-assembled parts. The invention also relates to a drum brake and a motor vehicle and to a method for assembling a carrier structure.

Description

technical field [0001] The invention relates to a carrier structure for a drum brake, which is used for fastening an eccentric shaft of a drum brake in a journal-fitting manner and for fastening a brake cylinder of a drum brake, which The eccentric shaft extends substantially parallel to and spaced from the rear axle. The invention also relates to drum brakes and motor vehicles. The invention also relates to a method for assembling the carrier structure. Background technique [0002] Drum brakes on the rear axle of at least large motor vehicles comprise a brake cylinder, a brake lever arm connected to the brake cylinder, and an eccentric shaft connected to the brake lever arm and provided with an S-shaped cam, whereby During braking, the braking force is arranged to be transferred from the brake cylinder to the brake lever arm, which rotates the eccentric shaft, so that the S-shaped cam turns and thereby pushes out the brake shoes, which in turn is pressed against the bra...
