Embodiment Construction
[0017] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0018] The embodiment of automobile engine suspension device among the present invention: as figure 1 and figure 2 As shown, the suspension device includes an upper shock-absorbing pad 1, a support plate 2 and a lower shock-absorbing pad 3 stacked sequentially from top to bottom, and the upper shock-absorbing pad 1 and the lower shock-absorbing pad 3 are circular pie-shaped spacers. , A sleeve-shaped spacer 4 and a dumbbell-shaped air bag 5 are installed between the upper shock-absorbing pad 1 and the lower shock-absorbing pad 3 . Among them, the airbag 5 and the spacer 4 are coaxially distributed in the center of the upper shock-absorbing pad 1 and the lower shock-absorbing pad 3, and the spacer 4 ...

The invention relates to an automobile engine mounting device. The automobile engine mounting device comprises an upper damping cushion, a supporting plate and a lower damping cushion which are sequentially stacked from top to bottom. A dumbbell-shaped air bag is installed between the upper damping cushion and the lower damping cushion. The slender waist portion of the air bag is arranged in a corresponding central through hole in the supporting plate in a penetrating mode. Cover bodies at the two ends of the air bag are stopped on the edges of corresponding end holes of the central through hole, and the two ends of the air bag are prearranged inside the bottom of the upper damping cushion and the top of the lower damping cushion. The upper damping cushion and the lower damping cushion are connected through the dumbbell-shaped air bag, the air bag has the certain elastic buffering and supporting effect on one of the upper damping cushion and the lower damping cushion and has the elastic opening effect on the other of the upper damping cushion and the lower damping cushion, and the pressed end of the air bag becomes soft and the unpressed end of the air bag becomes hard by means of airflow movement between the cover bodies at the two ends of the air bag, so that the upper damping cushion and the lower damping cushion participate in damping actions; by means of the principle that the upper damping cushion and the lower damping cushion share vibration pressure, the damping rigidity during one-way vibration is improved, and the damping effect is enhanced.
Description
technical field [0001] The invention belongs to the field of automobile engine shock absorption, in particular to an automobile engine suspension device. Background technique [0002] At present, the automobile engine converts the internal energy of the fuel into kinetic energy through the crank-slider mechanism, because the speed of the crank-slider mechanism is not linear, and the speed varies from fast to slow in the four strokes, and the direction of movement of the slider varies. There is a change, which causes the engine to generate greater vibration, and the explosive force of the power stroke intensifies this vibration. Although various balancing methods are used to reduce this vibration, it is still impossible to truly eliminate this vibration. , and if this kind of vibration is transmitted to the frame, it will definitely affect the ride comfort, and the method of reducing the vibration transmitted to the frame is generally to install a shock absorber, and the basi...
