Summary of the invention
Technical matters to be solved by this invention is to provide a kind of engine front mounting cushion assembly, and to solve available engine front suspending cushion assembly intensity difference, effectiveness in vibration suppression is bad, the problem cannot accurately located during installation.
In order to solve the problem, the technical solution used in the present invention is: this engine front mounting cushion assembly, include rubber block, there is a purchasing ore being provided with support cover, described rubber block is contained in the support cover of described purchasing ore by base plate, inner frame is embedded with on the top of described rubber block, described inner frame is provided with the locating dowel pin of the support cover end face stretching out described purchasing ore, described base plate is provided with the limit dais protruded downwards, and described purchasing ore, described inner frame, described base plate are connected with described rubber block sulfuration.
In above-mentioned engine front mounting cushion assembly technical scheme, technical scheme can also be more specifically: the support cover top of described purchasing ore is provided with opening, and bottom is provided with the adapter plate stretched laterally, and described adapter plate is provided with multiple first mounting hole; Described inner frame is provided with multiple second mounting hole, and outside is provided with the boss inserting described rubber block, and described boss is provided with multiple through hole; Described rubber block bottom is stretched out described adapter plate and is connected with described base plate.
Further, described rubber block comprises and connects upper rubber block outside described inner frame and the lower rubber block be connected bottom described inner frame, annular groove is provided with in the upper end of described upper rubber block, be provided with gap between the outside of described lower rubber block and the inwall of described support cover, the height of described upper rubber block is less than the height of described lower rubber block.
Further, the lower surface of described base plate and the adapter plate bottom surface distance of described purchasing ore are 10 millimeters.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention has a purchasing ore being provided with support cover, rubber block is contained in the support cover of purchasing ore by base plate, inner frame is embedded with on the top of rubber block, inner frame is provided with the locating dowel pin of the support cover end face stretching out purchasing ore, base plate is provided with the limit dais protruded downwards, and purchasing ore, inner frame, base plate are connected with rubber block sulfuration.Because purchasing ore and inner frame add the intensity of this engine front mounting cushion assembly, this engine front mounting cushion assembly only need be installed and can play support and damping of vibrations, good damping result, during installation, the locating dowel pin of inner frame upper end coordinates with the knock hole of engine cylinder body support frame, the limit dais of base plate coordinates with the position-limited trough on cross member of frame, ensures to install accurate positioning.
2, on the boss of inner frame, be provided with multiple through hole, increase the area that inner frame is connected with rubber block sulfuration, connect more reliable.
3, rubber block comprises upper rubber block and lower rubber block, the height of upper rubber block is less than the height of lower rubber block, the impulsive force that lower rubber block bears is greater than the impulsive force that upper rubber block bears, annular groove is provided with in the upper end of upper rubber block, for rubber block stress deformation has reserved space, gap is provided with, for when inner frame is connected with engine cylinder body support frame, hold-down bolt reserves assembly space between the outside of lower rubber block and the inwall of support cover.
4, the lower surface of base plate and the adapter plate bottom surface distance of purchasing ore are 10 millimeters, during installation, purchasing ore adapter plate is connected with cross member of frame, and rubber block makes the lower surface of base plate and the plane of cross member of frame fit by compression, rubber block can not be deviate from purchasing ore, and reliability is high.
