Accompanying drawing explanation
Fig. 1 is back suspension device of engine structural representation of the present utility model.
Fig. 2 is back suspension device of engine cross-sectional view of the present utility model.
Fig. 3 is the spacing schematic diagram of back suspension device of engine of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, the utility model discloses a kind of spacing back suspension device of engine of three degree of freedom that has, comprise upper skeleton 1, lower skeleton 2, described upper skeleton 1 can move with respect to described lower skeleton 2, described upper skeleton 1 comprises attaching parts 11 and two U-shaped locating parts 12, two described U-shaped locating parts 12 are described attaching parts 11 two ends for rotational symmetry is connected in, the opening of two described U-shaped locating parts 12 is all towards described attaching parts 11, and described lower skeleton 2 two ends embed respectively in the opening of two described U-shaped locating parts 12.
The utility model is realized the limit function of 3DOF on same suspending simultaneously, simple in structure, conveniently manufacture, reduce costs.
Described lower skeleton 2 is provided with the lower skeleton positioning plate 21 moving forward for limiting upper skeleton 1, described lower skeleton positioning plate 21 is positioned at described upper skeleton 1 one sides, described upper skeleton 1 is provided with the upper skeleton positioning plate 13 moving backward for limiting upper skeleton 1, described upper skeleton positioning plate 13 is positioned at described lower skeleton 2 one sides, and described upper skeleton positioning plate 13 and described lower skeleton positioning plate 21 are all positioned at the same side.
Described attaching parts 11 is c-shaped, and the C shape of described attaching parts 11 is opening up.
Described lower skeleton positioning plate 21 is positioned at described upper skeleton 1 midway location place, and described upper skeleton positioning plate 13 is two, and two described upper skeleton positioning plates 13 lay respectively at described upper skeleton 1 two ends.
Between described upper skeleton 1 and described lower skeleton 2, be filled with elasticity packed layer 3, described elasticity packed layer 3 is made for elastomeric material.
Described lower skeleton 2 is provided with hold-down bolt 22, and described hold-down bolt 22 is at least two.
Described upper skeleton 1 is provided with the tapped bore 14 for stationary engine, and described tapped bore 14 is at least two.
Upper skeleton 1 is movable parts (be fixed on driving engine, move with driving engine); Lower skeleton 2 is fixed parts (being fixed on vehicle frame); Rubber bodies plays vibration reduction and cushioning effect, and the vibration of decay driving engine is delivered on vehicle frame.
Realize the spacing principle of 3DOF:
Z direction is spacing: when upper skeleton 1 above-below direction when motion (Z direction), U-shaped locating part 12(upper skeleton blacking place of upper skeleton 1) bump with the edge (lower skeleton blacking place) of lower skeleton 2, thus Z direction is carried out spacing, see Fig. 3.
Y-direction is spacing: in the time that upper skeleton left and right directions moves (Y-direction), U-shaped locating part 12(upper skeleton blacking place of upper skeleton) bump with the edge (lower skeleton blacking place) of lower skeleton 2, thus Y-direction is carried out spacing, see Fig. 3.
Spacing around X-direction (around engine crankshaft direction): when upper skeleton 1 is in the time that X-axis moves clockwise, left side U-shaped locating part 12 lower edges (upper skeleton 1 blacking place) of upper skeleton 1 bump with lower skeleton 2 left side edge (lower skeleton blacking place), right side U-shaped locating part 12 upper limbs (upper skeleton blacking place) of upper skeleton 1 bump with lower skeleton 2 right side edge (lower skeleton blacking place), thereby realize clockwise spacing around X-axis.Conter clockwise when motion, according to this symmetry in the definite plane of Z-X of rear-suspending, also can realize spacingly, see Fig. 3.
It is spacing that the utility model can also be realized directions X: in the time that upper skeleton 1 travels forward (directions X forward), upper skeleton 1 bumps with lower skeleton positioning plate 21, realizes directions X forward spacing; In the time that upper skeleton 1 moves backward (directions X negative sense), upper skeleton positioning plate 13 bumps with lower skeleton 2, is to think that directions X negative sense is spacing; Directions X refers to upper skeleton 1 aspect that seesaws.
The utility model has been realized all spacing requirements of driving engine on rear-suspending, therefore, in the time that about design suspends, without considering 4DOF position limiting structure, has simplified left and right mounting structure again, and convenient manufacture reduced the whole series cost that suspends.
The utility model is realized the limit function (having realized the limit function to all sense of motions of driving engine) of 4DOF on same suspending simultaneously.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
