Generally, the conventional hydraulic mount decoupling structure can only decouple the amplitude between PP01 and PP06; however, under relatively large working conditions, the vibration amplitude exceeds PP06, which mainly highlights the damping characteristics. Therefore, under relatively large working conditions The conventional hydraulic mount decoupling structure can only release the damping performance of the amplitude below PP06 first, and the remaining amplitude can increase the damping through the flow channel, thereby reducing and lagging the damping performance

The invention discloses a novel hydraulic suspending decoupling structure, comprising a circular decoupling membrane, a runner plate and an annular runner cover plate. The novel hydraulic suspending decoupling structure is characterized in that the runner cover plate is fixed at the top of the runner plate, a first annular convex wall which is raised upward along an axial direction is arranged at the bottom of the runner plate, an annular runner is arranged on the outer side of the first annular convex wall on the runner plate, a circular air chamber is arranged on the inner side of the first annular convex wall on the runner plate, the decoupling membrane covers the air chamber, a liquid pouting hole which is communicated with the runner is formed on the side wall of the runner plate, a runner opening which penetrates through the thickness direction of the runner cover plate is formed on the runner cover plate corresponding to the position of the liquid pouring hole, an air vent is formed at the bottom of the runner plate, and the air chamber is communicated with outside through the air vent. The novel hydraulic suspending decoupling structure has the advantages that the hydraulic suspending decoupling structure effectively increases damping property of hydraulic suspension, and vibration of an automobile in a relatively large working condition is damped in time and effectively.
Description
Technical field [0001] The invention relates to a decoupling structure, in particular to a new type of hydraulic suspension decoupling structure. Background technique [0002] The shape of the decoupling membrane of the conventional hydraulic suspension decoupling structure is simple, the decoupling membrane of the conical hydraulic suspension is usually a circular piece, and the decoupling membrane of the trapezoidal hydraulic suspension is usually a rectangular piece. Generally, the conventional hydraulic mount decoupling structure can only decouple the amplitude between PP01~PP06; and the amplitude of vibration exceeds PP06 under larger working conditions, which mainly highlights the damping characteristics, so under larger working conditions The conventional hydraulic mount decoupling structure can only release the amplitude damping performance below PP06, and the remaining amplitude can increase the damping through the flow channel, thereby reducing and lagging the damping p...
