Abstract
A sleeve-type rubber shock absorber with hydraulic damping for mounts in motor vehicles includes an inner mounting sleeve (1), an outer mounting sleeve (2) surrounding same at a radially spaced location, at least one elastomer body (3), which is adheringly arranged between the two mounting sleeves and forms at least one chamber (4) filled with hydraulic damping agent. A cap (5) sealingly closes the sleeve-type rubber shock absorber, forming a second chamber (6). A channel plate (7) is provided which contains a throttle channel (7.1) connecting the chambers (4 and 6), wherein the outer bearing sleeve (2) has at least two different external diameters, of which the mainly radially loaded area of the smaller diameter is inserted into the motor vehicle component (8). At least two stop buffers (9) are arranged distributed over the circumference and are provided on the corresponding area of the inner mounting sleeve (1). The area of the larger diameter contains the chambers (4, 6), which are separated by the channel plate (7) and are filled with damping agent. The preferably two-part channel plate (7) has a support part (7.2) with the throttle channel (7.1) as well as a cover (7.3) closin…
