Specific embodiment
The present invention is described further now in conjunction with attached drawing.
Referring to fig. 2,3, the present invention is a kind of engine shock absorbing device of lightweight variable frequency, including die forging adapter,
Elastic vibration isolation structural member, connector, the both ends of elastic vibration isolation structural member 2 are respectively equipped with a die forging adapter 1, elastic vibration isolation knot
In the end insertion die forging adapter 1 of component 2, and it is fixed using connector 3, in engine luggine, elastic vibration isolation structural member 2
While vibration is isolated, it will be passed after vibration decaying, reduce the oscillating load on chassis and vehicle body, change and be transmitted to vehicle
The vibration characteristics of body structure, the risk of the fatigue failure of section components, extends corresponding component caused by reducing because of vibration
Service life is made that contribution indirectly to improve vehicle security.
Referring to Fig. 9,10, die forging adapter 1 is made of die forging blank through drilling, tapping.Die forging blahk structure is sufficiently effective
Ground utilizes the mechanical characteristic of material, reduces unnecessary waste of material, that is, improves stock utilization, therefore not only substantially subtracts
The consumption of few raw material simplifies process, and keeps structural mechanical property constant, and product weight and processing cost effectively drop
It is low.
Referring to fig. 4,5, die forging adapter 1 includes connecting pin 1, connecting pin 2 12, on rear side of the lower end of connecting pin 1 with
Connection on front side of the upper end of connecting pin 2 12, connecting pin 1, connecting pin 2 12 are respectively equipped with pre-and post perforative through-hole, connecting pin one
11 through-hole is set on engine and chassis seating, and the through-hole of connecting pin 2 12 is set in the end of elastic vibration isolation structural member 2.
Referring to Fig. 6,7, die forging adapter 1 includes connecting pin 1, connecting pin 2 12, the front side lower end of connecting pin 1 with
Connection in the middle part of the rear side of connecting pin 2 12, connecting pin 1 are equipped with upper and lower perforative through-hole one, and connecting pin 2 12 is equipped with left and right and passes through
The through-hole two worn, the through-hole one of connecting pin 1 are set on engine and chassis seating, and the through-hole two of connecting pin 2 12 is arranged
