Abstract
A hydraulic damping bush, more particularly in automotive applications, damps loads in a main loading direction. The bush includes an inner sleeve, an outer sleeve, a resilient mounting assembly disposed between the inner sleeve and the outer sleeve, as well as at least one end cap connecting the inner sleeve to the outer sleeve. The at least one end cap caps the space enclosed by the inner sleeve and outer sleeve from the environment. Two chambers are provided charged with a hydraulic damping fluid and interconnected via a transfer duct. The main loading direction is oriented parallel to a longitudinal axis of the inner sleeve and outer sleeve. The end caps can be formed separate from the resilient mounting assembly. Each of the chambers is defined by the resilient mounting assembly or a component adjoining the latter or by one of the end caps. This permits optimum material compatibility for facilitated production and assembly as well as a modular configuration of the bush.
