A kind of vehicular engine mounting structure
Technical field
The present invention relates to a kind of vehicular engine mounting structure.
Background technology
The power assembly arrangement of current pony car is mostly horizontal, and fixed form uses or three-point mount, position at 4 points
Suspension on the left of power assembly is generally the suspension of cylindrical type sleeved rubber, and this kind suspension is easily worked, technical maturity, rubber
The design of structure is simple, low cost.
The suspension of cylindrical type sleeved rubber needs diameter to can be only achieved Structural Design Requirement, this feelings on certain size
Condition needs sufficiently large space to arrange parts;Rubber spring along the rigidity on the direction of geometrical central axis much smaller than other two
Individual direction, and be difficult adjustment, therefore displacement when power assembly is moved in this direction than larger, it is necessary in bushing two
Increase bumper between side skeleton body and support to be any limitation as;Because the poor rigidity on three directions is away from larger, cause whole
The decoupling effect of suspension system is very poor, is unfavorable for the lifting of vehicle NVH performances.
The content of the invention
The present invention provides a kind of vehicular engine mounting structure, it is therefore an objective to make the rigidity in all directions more reasonable.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:A kind of vehicular engine mounting structure,
Including mounting bracket, suspend frame body, be located on mounting bracket supporting nail and be located at suspension frame body lasso on and
Allow supporting nail through rubber spring, rubber spring is located above mounting bracket, rubber spring using four muscle structure.
The rubber spring is dish-like.
The top of the rubber spring be provided with upper limit plate, upper limit plate and with allow it is described supporting nail through hole.
The axis perpendicular of the length direction of the upper limit plate and the supporting nail.
The bottom of the rubber spring is provided with lower limiting board, lower limiting board and with allowing the top of the mounting bracket to pass through
Hole.
The lower limiting board is parallel with the upper limit plate.
There is for limiting the spacing rubber of the upper limit plate and the lower limiting board vulcanization in the suspension frame body
Position block.
The present invention vehicular engine mounting structure, the direction of rubber spring is adjusted to it is consistent with vehicle Z-direction, by selecting
Dish-like, required space is greatly reduced in z-direction;Rubber spring is using the structure of four muscle, rigidity in all directions
It is more reasonable.
Brief description of the drawings

Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Explanation, it is therefore an objective to help those skilled in the art to the present invention design, technical scheme have more complete, accurate and deep reason
Solution, and contribute to it to implement.
As depicted in figs. 1 and 2, the invention provides a kind of vehicular engine mounting structure, including mounting bracket 5, suspension
Frame body 1, the supporting being located on mounting bracket 5 follow closely 7 and are located on the lasso 11 of suspension frame body 1 and allow supporting nail 7 to wear
The rubber spring 3 crossed, rubber spring 3 is located at the top of mounting bracket 5, and rubber spring 3 uses the structure of four muscle.Suspend skeleton sheet
Body 1 is to be used to be connected with engine, and the lasso 11 of suspension frame body 1 is located at the top of mounting bracket 5, and lasso 11, which has, to be accommodated
The endoporus of rubber spring 3, rubber spring 3 vulcanizes on lasso 11, so as to be closely joined together with suspension frame body 1.
As preferred, as depicted in figs. 1 and 2, rubber spring 3 is dish-like, setting direction and the vehicle Z of rubber spring 3
To consistent, rubber spring 3 is from dish-like, so that required space is greatly reduced in z-direction.And rubber spring 3 is using tool
There is the structure of four muscle, rigidity in all directions is more reasonable.
As depicted in figs. 1 and 2, it is provided with a upper limit plate 2 at the top of rubber spring 3, upper limit plate 2 and with allowing supporting
The hole that nail 7 is passed through.Supporting nail 7 is to be vertically arranged on mounting bracket 5, and supporting is followed closely in 7 lower end insertion mounting bracket 5, upper end
Protrude upward, upper limit plate 2 is horizontally disposed, the axis perpendicular of the length direction and supporting nail 7 of upper limit plate 2.
As depicted in figs. 1 and 2, it is provided with a lower limiting board 4 in the bottom of rubber spring 3, lower limiting board 4 and with allowing suspension
The hole that the top of support 5 is passed through.Lower limiting board 4 is parallel with upper limit plate 2, is also horizontally disposed.Upper limit plate 2 and lower limiting board
4 top and bottom respectively with rubber spring 3 are fixedly connected, and three is assembled together into an entirety.
As preferred, as depicted in figs. 1 and 2, sulphur is distinguished on the top surface of the lasso 11 of suspension frame body 1 and bottom surface
Change has for the rubber limited block 6 spacing to upper limit plate 2 and lower limiting board 4, when mounting bracket 5 is moved, upper limit
The motion of plate 2 and lower limiting board 4 is stopped by rubber limited block 6, serves spacing effect.
The mounting structure of above-mentioned vehicular engine, direction and structural adjustment by rubber spring 3 make mounting structure three
The rigidity in direction is more reasonably distributed, and the result finally analyzed shows that power assembly modal distribution is concentrated very much, and decoupling effect is fine.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that method of the present invention design and technical scheme are carried out is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
