The specific embodiment
For technical matters, technical scheme and advantage that embodiments of the invention will be solved is clearer, will combine accompanying drawing and specific embodiment to be described in detail below.
Embodiments of the invention still need improved problem to three pendulum-type power assembly suspension system in the prior art aspect car load traveling comfort and noise, a kind of overall comfort and noise aspect three pendulum-type power assembly suspension system and automobile with this system preferably are provided.
On the one hand, the present invention provides a kind of three pendulum-type power assembly suspension system, to shown in Figure 10, comprises left mounting assembly 1, right mounting assembly 2 and back mounting assembly 3 like Fig. 1, wherein:
Left side mounting assembly 1 is used to be arranged in the left side of dynamic assembly, and an end is connected with gear-box bracket, and the other end is used for and body contact;
The position and the annexation thereof of left mounting assembly, right mounting assembly and back mounting assembly that the present invention has passed through optimal design, thus the performance of vehicle aspect overall comfort and noise improved.Particularly; 1, right mounting assembly is arranged in the upper right side of dynamic assembly; Its effect is to go up fulcrum as one of dynamic assembly, through its higher position, has strengthened the arm of force of dynamic assembly rotation and has reduced the dynamic assembly moment of torsion and be delivered to the application force on the right mounting assembly; And through the big rigidity of right mounting assembly fore-and-aft direction, the rotation of controlling dynamic assembly more easily reaches moves; 2, right mounting assembly position is higher, and this position is lower for the susceptibility of body vibrations, and is less to occupant's traveling comfort influence; 3, back mounting assembly horizontal arrangement is in lower position, the dynamic assembly back lower place, and back mounting assembly only receives the application force of fore-and-aft direction, and the power of vertical direction and left and right directions is almost nil, can reduce excitation on the vertical direction to the influence of vehicle body; 4, the combined arranging mode of right mounting assembly and back mounting assembly; Because right mounting assembly position is higher; Back mounting assembly position is lower, and the arrangement of this pendulum model is the angle and the displacement of the turn of engine under the control limit operating mode effectively.
For improving vehicle performance, right mounting assembly 2 is preferably the hydraulic rubber mounting structure; Back mounting assembly 3 is preferably antitorque rod-pulling type mounting structure; And this structure is adopted in excellent 3 choosings of back mounting assembly: have first end and second end, the size of first end is greater than second end, and wherein, first end is used for being connected with the subframe support; Second end is used for being connected with driving engine; Link to each other through rigid support between first end and second end.And first end and second end all are preferably the rubber bush structure.
In addition; The structure of each support relevant with left mounting assembly 1, right mounting assembly 2 and back mounting assembly 3 has been shown among Fig. 2 to Figure 10; Wherein, the 4th, the attachment point of the engine side mounting bracket of left mounting assembly, the 5th, the attachment point of the body side mounting bracket of left mounting assembly; 6 also is the attachment point of the body side mounting bracket of left mounting assembly; The 7th, the attachment point of the body side mounting bracket of right mounting assembly, the 8th, the attachment point of the body side mounting bracket of right mounting assembly, the 9th, the attachment point of the engine side mounting bracket of right mounting assembly; The 10th, the attachment point of the body side mounting bracket of back mounting assembly, the 11st, the attachment point of the engine side mounting bracket of back mounting assembly.
Certainly, should be understood that the structure of each support shown in Fig. 2 to Figure 10 is merely for example, those skilled in the art can adopt the support of various other structures on the basis of principle of the present invention, all do not influence the realization of technical scheme of the present invention.
To sum up; Bikini pendulum model suspension system of the present invention is regulated the rotating fulcrum that can be used as dynamic assembly top through the height and the rigidity of right mounting assembly; The driving engine bottom can be passed through the rigidity of back mounting assembly fore-and-aft direction and regulate the control that realizes the swing of driving engine bottom, and for the vibration of little amplitude, the displacement of driving engine and rotation all are very small; The vibration that mainly is little displacement can be delivered on the vehicle body through suspending, and influences the traveling comfort and the noise of car load.Transport according to power; Excitation frequency doubly can reduce 85% greater than natural frequency
; Therefore the rigidity of mounting assembly is more little; Can effectively reduce the power that driving engine is delivered to vehicle body more; And one of very big advantage of three pendulum-type suspension system is that the vertical direction rigidity of back mounting assembly is almost nil; Power after then driving engine passes on mounting assembly and the body contact point is also almost nil, can effectively reduce the influence of the exciting force of vertical direction to vehicle body like this; Two of advantage is the arrangement of right mounting assembly and the design of rigidity, and right mounting assembly position is higher, and this position is lower for the susceptibility of body vibrations, and is less to occupant's traveling comfort influence; Three of advantage is the combined arranging mode of right mounting assembly and back mounting assembly; Because right mounting assembly position is higher; Back mounting assembly position is lower, and the arrangement of this pendulum model is the angle and the displacement of the turn of engine under the control limit operating mode effectively; Four of advantage is that three pendulum-type suspension system arrangement structure is simple, is easy to realize, and practices thrift cost.
On the other hand; The present invention also provides a kind of automobile, and it has above-mentioned three pendulum-type power assembly suspension system, and is extremely shown in Figure 10 like Fig. 1; This three pendulum-type power assembly suspension system comprises left mounting assembly 1, right mounting assembly 2 and back mounting assembly 3, wherein:
Left side mounting assembly 1 is arranged in the left side of dynamic assembly, and an end is connected with gear-box bracket, the other end and body contact;
The present invention through optimal design the position and the annexation thereof of left mounting assembly 1, right mounting assembly 2 and back mounting assembly 3, thereby improved the performance of vehicle aspect overall comfort and noise.
For improving vehicle performance, right mounting assembly 2 is preferably the hydraulic rubber mounting structure; Back mounting assembly 3 is preferably antitorque rod-pulling type mounting structure; And this structure of back mounting assembly 3 preferred employings: have first end and second end, the size of first end is greater than second end, and wherein, first end is used for being connected with the subframe support; Second end is used for being connected with driving engine; Link to each other through rigid support between first end and second end.And first end and second end all are preferably the rubber bush structure.
The above is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle according to the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
