The torsion beam bushing is transversely assembled on an automobile and comprises an inner core, a rubber part and an outer sleeve, the rubber part surrounds the inner core, and the outer sleeve surrounds the rubber part; the rubber parts comprise high-damping rubber parts and low-damping rubber parts which are not connected, the high-damping rubber parts are located on the left side and the right side of the inner core, the low-damping rubber parts are located on the upper side and the lower side of the inner core, and the high-damping rubber parts and the low-damping rubber parts are combined to surround the inner core; high-frequency jumping in the vertical direction of the vehicle body is isolated through the low-damping rubber part; the high-damping rubber part is used for attenuating large vibration in the horizontal direction, the rapid tightening effect is achieved, and therefore the vibration isolator can meet different vibration isolation requirements in the vertical direction and the horizontal direction; the high-damping rubber part and the low-damping rubber part are not connected, so that the high-damping rubber part and the low-damping rubber part can solve vibration in corresponding directions respectively; and mutual influence of the high-damping rubber part and the low-damping rubber part during vibration isolation work is avoided as much as possible.
本发明公开了一种扭力梁衬套,横向的装配于汽车上,其包括内芯、橡胶件和外套,所述橡胶件将内芯包围,外套将橡胶件包围;所述橡胶件包括不相连的高阻尼橡胶件和低阻尼橡胶件,高阻尼橡胶件处于内芯的左右两侧,低阻尼橡胶件处于内芯的上下两侧,高阻尼橡胶件和低阻尼橡胶件组合将内芯包围;通过低阻尼橡胶件来隔离车身垂直方向的高频跳动;通过高阻尼橡胶件用来衰减水平方向大幅的振动,起到了快速收束的作用,进而使得本发明能够兼具垂直方向和水平方向的不同隔振需求;高阻尼橡胶件和低阻尼橡胶件之间不相连,进而使得其两者能够各自解决对应方向的振动;进而尽量避免高阻尼橡胶件和低阻尼橡胶件在隔振工作时相互影响。
