The invention relates to the field of vehicle elastic damping devices, in particular to a hydraulic resistance bushing for a cab, which comprises a mandrel, a main spring component and an auxiliary spring component, the main spring component comprises an inner sleeve, an outer sleeve and a main rubber spring vulcanized between the inner sleeve and the outer sleeve, and the main rubber spring comprises a liquid flow channel and a hydraulic cavity communicated by the liquid flow channel. The auxiliary spring assembly comprises an auxiliary rubber spring capable of horizontally moving along the peripheral face of the central spindle so as to abut against the connecting support, a reset spring located between the main rubber spring and the auxiliary rubber spring so as to enable the auxiliary rubber spring to reset, and a second end cover located on the side, away from the main rubber spring, of the auxiliary rubber spring and arranged on the central spindle in a sleeving mode. A driving unit for driving the auxiliary rubber spring to move horizontally is arranged between the second end cover and the mandrel. The invention further provides a rigidity adjusting method of the hydraulic resistance bushing for the cab. The damping effect under the normal working condition and the stable operation working condition can be guaranteed, and the rigidity can be adjusted.
