Specific implementation
Contrast accompanying drawing below, by description to embodiment, to the specific embodiment of the present utility model, be described in further detail such as the effect of the mutual alignment between the shape of each related member, structure, the each several part and annexation, each several part and principle of work etc.:
As shown in drawings, the utility model is a kind of new type power assembly suspending cushion, comprises connecting arm 3, cushion branch unit 4, the outer skeleton 5 of cushion, interior pipe 6, rubber mount 7, cushion inner frame 8, set out turnup structure 11 at described cushion inner frame 8, on the described rubber mount 7 rubber boss 10 is set, on the described interior pipe 6 recessed positioning groove 9 is set, the positioning boss 12 and the positive stop 13 of projection is set on the described connecting arm 3.
Described turnup structure 11 is arranged on the edge of cushion inner frame 8, and is set to the outside structure of flange.
Described rubber boss 10 is arranged on and turnup structure 15 cooresponding positions, and described rubber boss 10 and turnup structure 15 link together by vulcanization.
Described positioning groove 9 is arranged on the inner end surface 16 of interior pipe 6.
Described positioning boss 12 is arranged on the connecting arm 3, is set to the structure that matches with positioning groove 9.
Described positive stop 13 is arranged on the both sides of the bolt hole that tie bolt 2 is installed.
Be set to exist the structure in gap between described rubber boss 10 and the positive stop 13.
The involved new type power assembly suspending cushion of the utility model is by tie bolt 2, connecting arm 3, and cushion branch unit 4, the outer skeleton 5 of cushion is formed; Wherein cushion branch unit 4 was that interference fit is in the same place with the outer skeleton of cushion, and cushion branch unit 4 is by interior pipe 6, rubber mount 7, and cushion inner frame 8 threes sulfide and form; Interior pipe 6 inside are processed with screw thread and can screw in for tie bolt 2.
One end of cushion inner frame 8 has been made two turnup structures (11), and the top sulfuration of flange has rubber boss 10, and the end limit of interior pipe 6 is processed with positioning groove 9; Can see from accompanying drawing, be processed with positioning boss 12 on the fitting surface of connecting arm 3 and interior pipe 6, being used for the both sides of circular hole of fitting-up bolt 2 on the connecting arm 3 stretches out two positive stops 13; After finishing assembling, exist the gap between rubber boss 10 and the positive stop 13.
As shown in Figure 2, front view of the present utility model is the installing condition of suspending cushion on real vehicle, and for ease of explanation, only the left side that is installed in engine bin with suspending cushion is an example; Vehicle in the process of moving because connecting arm 3 and dynamic assembly are rigidly connected, so connecting arm 3 also can move together with dynamic assembly; Under general operating mode, the amount of exercise of dynamic assembly on along continuous straight runs is little, and rubber boss 10 can not contact with positive stop 13, the variation that the gap between the two can be suddenly big or suddenly small; Under bad working environments, such as the sharp right-hand bend of vehicle high speed, under action of centrifugal force, dynamic assembly has the bigger displacement to left movement, gap between rubber boss 10 and the positive stop 13 can reduce rapidly at this moment, final positive stop 13 contact earlier pushes rubber boss 10 again, further increasing along with amount of compression, final rubber boss 10 can stop dynamic assembly to continue to move left because of the antagonistic force that is extruded distortion and produces, thereby has prevented that effectively dynamic assembly from mobilely damaging rubber mount 7 because of excessive to the left.As shown in Figure 3, the head of assembling back tie bolt 2 is on the right side of suspending cushion, and after the assembling of traditional suspending cushion, the head of tie bolt 2 is in the left side of suspending cushion, therefore compare with traditional structure, the utility model can go out the space of a bolt head in left side province, under same arrangement space, pipe outer face 14 is bigger apart from the gap of its peripheral parts in the new suspending cushion of this practicality, the phenomenon that pipe outer face 14 and its peripheral parts are dynamically interfered in the more difficult appearance.Shown in the front view of Fig. 2, after finishing, assembling to guarantee that the positioning boss 12 of connecting arm is in the positioning groove 9 of interior pipe 6, when like this tie bolt 2 being carried out pretension, can first captive joint arm 3, again tie bolt 2 is carried out pretension, at this moment positioning boss 12 just can prevent trackslipping of interior pipe 6 relative connecting arms effectively with positioning groove 9.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasions without improving, all in protection domain of the present utility model.
