Detailed description of the invention
Referring to Fig. 1, be subject to the energy-absorbing enlarger of force direction according to the change of the utility model one embodiment, comprise power side steering 1 and at least two hydraulic dampers 2 that level is installed, power side steering is connected with each hydraulic damper transmission respectively, and the power that the power of vertical direction is decomposed into multiple horizontal directions realizes amplification energy-absorbing.
Above-mentioned power side steering 1 comprises housing 11, top in housing is provided with the main piston 12 moving both vertically, bottom in housing is provided with the auxiliary piston 13 of at least two horizontal movements, between main piston and each auxiliary piston, be connected by the hinged transmission of connecting rod 14 respectively, moving both vertically of main piston changed into the horizontal movement of auxiliary piston; Each auxiliary piston is connected with each hydraulic damper transmission respectively, realizes and amplifies energy-absorbing.
Fig. 2 is energy-absorbing amplification principle figure of the present utility model. As shown in the figure, connecting rod initial state is straight line B, and fortune operated condition is dotted line A. From geometrical relationship, ratio horizontal and vertical deviation variation is 1.3:1. This is the multiplication factor of single connecting rod, if increase the number of horizontal direction damper, can amplify at double. Suppose that horizontal direction hydraulic damper number is 2, multiplication factor is 2.6 times, has if required (hydraulic damper space being installed unrestricted) can planar increase radially multiple (4 ~ 6) hydraulic damper. So, can realize the amplification of moving displacement, the total energy absorption of hydraulic damper is doubled and redoubled.
DY series rubber shock absorber inner chamber is installed after this mechanism, hydraulic damper can be installed on to two ends, transmits impulsive force to hydraulic damper with mechanism, and displacement enlargement, makes it to meet the requirement of hydraulic damper movement travel.
The anti-impact components and parts such as single-layer partiting polarization device, narrow space, very difficult normal mounting hydraulic damper, using this mechanism can realize hydraulic damper level installs, the impact resistance of raising equipment, realizes hydraulic damper replacement stop for single-layer partiting polarization necessary condition is provided.
Metal plate type spring and dish formula spring can connect with this mechanism, realize the interlock of vibration isolation and impact, and its scope of application is expanded, and impact isolation effect and obviously promote.
