Description
Technical Field
The invention relates to a switching type semi-active suspension runner system structure, and belongs to the field of automobile power assemblies.
Background
The powertrain is generally divided into a transverse arrangement and a longitudinal arrangement. When arranged transversely, it typically includes an engine mount, a transmission mount, one or two pendulum supports. Longitudinally disposed, it typically includes two left and right disposed engine mounts and a rear disposed transmission mount.
The engine suspension is an important part of an automobile power assembly and mainly has the following functions:
1) bearing the static and dynamic loads of the power assembly;
2) the connecting structure is easy to be connected with adjacent parts, and the collision and interference of the power assembly and the adjacent parts are limited;
3) isolating vibration; isolating vibration due to the inertial uneven forces of the powertrain, and isolating powertrain resonance due to road jolts.
4) Noise isolation: the power assembly is prevented from generating noise due to the combustion of gasoline (or diesel oil), the movement of a piston, the movement of a gear and the like and transmitting the noise to the vehicle body;
on the basis of meeting the performance, the power assembly suspension and the power assembly form a system. The early design needs to be integrally analyzed, and then the design of a single suspension is carried out according to the obtained dynamic and static rigidity target values and the spatial arrangement of each suspension. Because the engine suspension is directly connected with the engine, the comfort and the stability of the whole vehicle are directly influenced by the good design of the engine suspension.
Hydraulic engine suspensions were used in the 90 s of the 20 th century and consisted of two liquid-filled chambers. Through decades of development, compared with the traditional rubber suspension, the inertia channel-decoupling film type engine suspension has the advantages that the inertia channel-decoupling film type engine suspension shows a great damping characteristic when excited at low frequency and large amplitude (0-20 Hz +/-1 mm); the high-frequency small-amplitude excitation (20-200 Hz +/-0.1 mm) shows relatively low dynamic stiffness.
With the increasing demand for comfort in high-end cars, various host plants and component suppliers have been working on actively isolating the vibration of the powertrain. The switching type semi-active suspension developed by BOGE company can meet the requirements of different high-end vehicle types on vibration reduction and noise reduction.
The runner system is an important part of the engine suspension, and the design quality of the runner system is directly related to the liquid filling mode, the damping loss angle peak value, the peak frequency position, the volume of the suspension system, the dynamic stiffness of the assembly and other performances of the hydraulic suspension.
The switchable semi-active suspension can realize the characteristic of high frequency and low rigidity under the idle working condition; and under the driving working condition, the low-frequency large damping characteristic and the large rigidity characteristic are realized. The semi-active suspension is mainly applied to high-end vehicle types, and the development cost is high.
The development progress of each host factory for building high-end vehicle types is accelerated, the types are increased, the platform is formed, the modularization is realized, and the light weight is deepened. Suspension component suppliers are faced with how to design a product that can achieve as many performance requirements as possible with as few changes as possible.
