The invention discloses a composite damping shock absorption device for an automobile gearbox, and relates to the technical field of automobile gearbox protection devices, the composite damping shock absorption device comprises a gearbox main body and a shock absorption device main body, the shock absorption device main body is arranged at the bottom of the gearbox main body, and the lower surface of the shock absorption device main body is movably connected with a connecting bottom plate. Through the cooperation of the movable push rod, the elastic damping sleeve shell, the supporting block, the folding rod, the connecting rod and the spring, in the vibration process of the gearbox body, the elastic damping sleeve shell is extruded through the cooperation of the movable push rod and the supporting block, so that the elastic damping sleeve shell is elastically deformed; the folding rods are pushed to be separated gradually, the connecting rods are pushed to push the elastic damping sleeve shells to slide towards the two sides, meanwhile, the springs are stretched and elastically deformed, the elastically-deformed structure has the characteristic of recovering the deformation trend, impact force generated by vibration is weakened, and the overall stability of the device is improved.
本发明公开了一种汽车变速箱复合阻尼减震装置,涉及汽车变速箱防护装置技术领域,包括变速箱主体和减震装置主体,所述减震装置主体设置于变速箱主体的底部,所述减震装置主体的下表面活动连接有连接底板。本发明通过采用活动推杆、弹性减震套壳、支撑块、折叠杆、连接杆以及弹簧之间的配合,变速箱主体震动的过程中,通过活动推杆以及支撑块的配合,对弹性减震套壳产生挤压作用,使其发生弹性形变,当弹性减震套壳发生弹性形变时,推动折叠杆逐渐分开,并推动连接杆推动弹性减震套壳向两侧滑动,同时弹簧被拉伸,发生弹性形变,以上发生弹性形变的结构具备恢复形变趋势的特点,将震动产生的冲击力削弱,提高装置的整体稳定性。
