Referring to fig. 1-3, an inertia buffer mechanism for non-independent suspension includes a supporting axle 1, a supporting suspension 3 is fixedly mounted on two sides of the top end of the supporting axle 1 through a damping system 2, a set of first ear seats 4 is respectively disposed on two ends of one side of the supporting suspension 3, a buffering suspension 5 is disposed on the top end of the supporting suspension 3 and connected to the bottom end of the vehicle body, a set of second ear seats 6 corresponding to the two sets of first ear seats 4 is respectively disposed on two sides of the bottom end of the buffering suspension 5, the second ear seats 6 on the buffering suspension 5 are in transmission connection with the first ear seats 4 on the supporting suspension 3 through a first linkage strut 7, a second linkage strut 8 is movably sleeved inside the bottom end of the first linkage strut 7 through a pinned sleeve, the other end of the second linkage strut 8 is fixedly connected to a pinned sleeve inside a third ear seat 9 fixedly mounted on the bottom end of the supporting axle 1, a buffer spring 10 is movably sleeved on one side of the outer surface of the second linkage supporting rod 8 and positioned between the first linkage supporting rod 7 and the third ear seat 9.
Wherein, to buffering suspension 5 and its setting through the transmission connection between first linkage branch 7 and the support suspension 3, when the freight train that uses this dependent suspension is when carrying out the braking action, make buffering suspension 5 on it have the trend of moving forward, thereby in transmitting the shock-absorbing system 2 on the support suspension 3 through first linkage branch 7 with its "horizontal" inertia impact conversion that produces when braking, and then "digestion" that is fallen by the shock-absorbing spring or the damping system of "vertical" in shock-absorbing system 2, avoided this dependent suspension because of the horizontal impact damage problem that the brake inertia produced, improved its structural strength and life in the use effectively.
In the technical scheme, the first lug seat 4 on the supporting suspension 3 and the second lug seat 6 on the buffering suspension 5 are respectively and sequentially arranged along the advancing direction of the truck.
The relative position between the second ear mount 6 and the first ear mount 4 is set because the inertia impact generated by the vehicle during braking is along the forward direction of the vehicle, so that the inertia impact generated by the vehicle during braking can be effectively transferred to the interior of the shock absorbing system 2 and be "digested" by the interior.
In this technical scheme, the outside of first linkage branch 7 is established to be the quarter arc structure, and its point of being in pin joint with first ear seat 4 is located the one third department of first linkage branch 7 whole radian.
Wherein, to the setting of the outside arc structure of first linkage branch 7 to effectively improve its bearing strength when rotating inertial impact, make the overall structure nature of first linkage branch 7 higher, stability and reliability better, can adapt to effectively with the operating mode environment of high pressure high strength in.
