In order to improve effectiveness in vibration suppression, improve the travelling comfort of car load, better to protect quarry tipper power assembly bearing and reduce noise, the utility model provides a kind of power assembly vibration isolator.
For achieving the above object, a kind of power assembly vibration isolator, comprise holder cylinder, in holder cylinder, be provided with block rubber, the upper end of holder cylinder is stretched out in the upper end of block rubber, on block rubber, through there being screw rod, screw rod is gripped with the upper holder block that is provided with screw rod upper end by the lower lock block that is arranged on screw rod lower end, between upper holder block and block rubber, is provided with pressing plate.
As specializing, described holder cylinder comprises cylindrical shell and carrying flange, and carrying flange bends extension laterally from the top edge of cylindrical shell, and carrying flange is provided with mounting hole.
As specializing, described block rubber comprises lower bearing part and upper bearing part, lower bearing part is arranged in cylindrical shell, the edge of upper bearing part extends to form rubber flange laterally from the top edge of lower bearing part, rubber flange is carried by carrying flange, the upper surface of upper bearing part is spheric, is provided with through hole on block rubber.
As specializing, described upper holder block comprises the portion of stretching into and upper pressing part, above stretches into portion and upper pressing part and forms step, and the lower end of above stretching into portion is inserted in through hole, and pressing plate is enclosed within on insertion part and between upper pressing part and upper bearing part.
As improvement, between screw rod and block rubber, cover has sleeve.
As specializing, under lower lock block comprises, stretch into portion and lower joint, under the portion of stretching into extend in sleeve, lower joint is kept out by sleeve.
As improvement, holder cylinder underpart is stretched out in the lower end of lower bearing part, and the external part of lower bearing part is frustum type.
The beneficial effects of the utility model are: owing to being provided with holder cylinder, and block rubber is comprised of lower bearing part and upper bearing part, lower bearing part is arranged in holder cylinder, upper bearing part is by holding in the palm cylinder carrying, after quarry tipper power assembly is installed between upper holder block and upper cover plate, after quarry tipper power assembly is vibrated, upper bearing part and lower bearing part all can be out of shape, but because the end face of upper bearing part is spheric, and the rubber flange of upper bearing part is carried by carrying flange, like this, the middle part of upper bearing part is first subject to power and power is delivered to lower bearing part, in the time of by upper and lower bearing part, be out of shape and carry out buffering vibration, after block rubber is deformed to a certain degree, the amount of deformation of upper bearing part is greater than the amount of deformation of lower bearing part, therefore, whole vibration isolator has played linear buffer function, vibration damping effective, can also prevent resonance, to improve the travelling comfort of car load, better protect quarry tipper power assembly bearing and reduce noise.Because the external part of lower bearing part is frustum type, descend like this middle part non-deformability of bearing part good, good damping result.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1 to Figure 3, quarry tipper power assembly vibration isolator comprises holder cylinder 1, block rubber 2, sleeve 3, screw rod 4, upper holder block 5, lower lock block 6, pressing plate 7, upper cover plate 8, nut 9.
Holder cylinder 1 comprises cylindrical shell 11 and carrying flange 12, and carrying flange 12 bends extension laterally from the top edge of cylindrical shell 11, on carrying flange 12, is provided with mounting hole 121, for holder cylinder 1 is fixed to vehicle frame.
Block rubber 2 comprises lower bearing part 21 and upper bearing part 22, lower bearing part 21 is arranged in cylindrical shell 11, the edge of upper bearing part 22 extends to form rubber flange 221 laterally from the top edge of lower bearing part, rubber flange 221 is by 12 carryings of carrying flange, the upper surface of upper bearing part 22 is spheric, is provided with through hole 23 on block rubber.Holder cylinder underpart is stretched out in the lower end of lower bearing part 21, and the external part of lower bearing part is frustum type.
Sleeve 2 is arranged in through hole 23, and the upper end of sleeve 2 stretches out the upper end of holder cylinder 1, and the upper end of sleeve 2 and block rubber upper end are contour, and the lower end of holder tin 1 is stretched out in the lower end of sleeve 2, and the lower end of sleeve 2 and block rubber lower end are contour.
Described screw rod 4 is through through hole sleeve 3.Described upper holder block 5 is arranged on the middle part of screw rod 4, upper holder block 5 comprises the portion of stretching into 52 and upper pressing part 51, on stretch into portion 52 and upper pressing part 51 and form steps, on stretch into portion 52 lower end be inserted in sleeve 3, on upper insertion part 52, between upper pressing part 51 and upper bearing part 22, cover has described pressing plate 7, upper end at screw rod 4 is provided with upper cover plate 8 by nut 9, has living space, for quarry tipper power assembly is installed between upper cover plate 8 and upper pressing part.
