Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Referring to Fig. 1, Fig. 2, the present invention provides a kind of new type of passive suspension containing used container, including supporting spring 1, auxiliary damper 2, used container 3, main antivibrator 4 and secondary spring 5,
Described auxiliary damper 2 is connected with used container 3 and is defined low-frequency vibration defecator, described secondary spring 5 define dither defecator in parallel with main antivibrator 4, described dither defecator is connected with low-frequency vibration defecator and is defined full rate vibrative filter; Described full rate vibrative filter is in parallel with supporting spring 1, and the upper end thereof of this parallel-connection structure is on vehicle body, and lower end is articulated with on wheel.
Described low-frequency vibration defecator is positioned at the top of dither defecator, and, auxiliary damper 2 is positioned at the top of used container 3.
The upper extreme point of described support spring 1 and the upper extreme point of auxiliary damper 2 are hinged, the upper extreme point of the lower extreme point of auxiliary damper 2 and used container 3 is hinged, upper extreme point after the lower extreme point of used container 3 is in parallel with secondary spring 5 and main antivibrator 4 is hinged, and the lower extreme point of secondary spring 5 and the lower extreme point after main antivibrator 4 parallel connection and support spring 1 is hinged.
The upper extreme point of the upper extreme point and auxiliary damper 2 that support spring 1 is hinged on sprung mass 6, support the lower extreme point of spring 1, the lower extreme point of secondary spring 5 and the lower extreme point of main antivibrator 4 and be hinged on unsprung mass 7, the upper fulcrum of the lower fulcrum of unsprung mass 7 and tire equivalent spring 8 is articulated and connected, and thus completes the installation of a kind of new type of passive suspension containing used container.
