Crossbar vibrating decrease device of toransuhuahuida

摘要

(57) Abstract Objective Without increasing the rigidity of the crossbar when workingThere are times when the vibration is decreased. Constitution Between transfer bar 1 the side rack the crossbar which is done- Providing the vibration-proof chamber 7 inside 2, inside these vibration-proof chamber 7 core 8aThe mass where around part is overturned at least with cushion 8b8 being something which convolution unrestrictedly is stored, crossbar 2 when workingVibration the above-mentioned mass 8 in kinetic energy and vibration-proof chamber 7 inner wallsConvert to the collision sound energy which is generated the occasion where it collidesIt is possible to decrease with.
