Detailed description of the invention
First, it should be noted that, the principle of design of this Y type link lever rear suspension, constructional feature and advantage will be illustrated by way of example below, but all descriptions are only used to be described, and should not be understood as any restriction is formed to the present invention.In addition, described in each embodiment mentioned by this paper or implicit any single technical characteristic, or be shown or implicit any single technical characteristic in the accompanying drawings, still can between these technical characteristics (or its equivalent), proceed combination in any or delete, thus obtain other embodiments of the present invention more that may directly do not mention in this article.
Incorporated by reference to referring to figs. 2 and 3, by these accompanying drawings illustrate in a schematic way a Y type link lever rear suspension of the present invention embodiment essential structure and by the assembly structure situation after its installation.
In the above-described embodiments, Y type link lever rear suspension mainly comprises main connecting rod 1, pipe link 2 and rocking arm 3, in preferred cases, Y type link lever rear suspension can also comprise the first support 4 and the second support 5, and they are rigidly connected with an end of main connecting rod 1 and the pontic of back axle 7 respectively.In this article, term " be rigidly connected " include but not limited to such as to weld, rivet, bolt connection etc. can be the existing mode of any one understood by one of ordinary skill in the art.Below will be described in detail for these parts above-mentioned.
Main connecting rod 1 is one of vitals in this Y type link lever rear suspension, pipe link 2, rocking arm 3 and auto body support (not shown) etc. is associated together by it.One end of main connecting rod 1 is hinged on this rocking arm 3 by the ball pivot 6 be located on rocking arm 3 one end, its other end then can be connected on auto body support by the second lining, or first connect the first support 4 by this second lining, and then be rigidly connected with auto body support, so just can ensure intactly to be delivered in side force when turning to of driving a vehicle on auto body framework.
As shown in Figure 2,3, one end of pipe link 2 is pivotally attached to by the 3rd lining on the pivoting point 8 that is positioned in the middle part of main connecting rod 1, and is pivotally attached on the pontic its other end being pivotally attached to back axle 7 by the 4th lining or by the 4th lining and is rigidly connected on above-mentioned second support 5 of back axle 7 pontic.At this it is important to note that the term occurred everywhere in this article " middle part ", it also not only refers to the position being in its absolute midway location with regard to length dimension, and should be understood as position therebetween for the extreme end on object.Such as, just include the position between two ends being in this main connecting rod 1 in the middle part of above-mentioned main connecting rod 1, in these positions, naturally also include the absolute middle part of this main connecting rod 1.
As a kind of illustrative case, the length of pipe link 2 specifically can be arranged to: this length equals or substantially equal the distance of fixing from pivoting point 8 to main connecting rod 1 and body support one end as shown in Fig. 2 or 3.Also need to point out at this, the term that occurs everywhere in this article " substantially equal/substantially identical " refer to for " equal/identical " this absolute situation any insubstantial deviations (such as, this may cause due to the reasons such as measuring tool, precision of manufacturing process), those skilled in the art can fully understand completely to this.As an example, when the length of pipe link 2 be 295mm, pivoting point 8 be 298mm to the spacing that main connecting rod 1 and body support fix one end time, just can think that above two numerical value are substantially equal/substantially identical.
For rocking arm 3, it is configured in the present invention across back axle 7 and in the support being connected to the pontic of this back axle 7 by the first lining or feature, its other end is then hinged by ball pivot 6 and main connecting rod 1 as previously mentioned.By adopting the arrangement after above this Optimal improvements, not only thoroughly can substitute the propelling rod in existing structure as previously noted, and can compact layout be realized.
As a kind of illustrative case, the second above-mentioned lining, the 3rd lining and the 4th lining can adopt doubly-linked direct type lining.In preferred cases, second lining, the 3rd lining and the 4th lining can be arranged to have identical or substantially identical size each other, these sizes comprise bushing inner diameter, Outer Diameter of lining, bush inside length (interlength), bushing outer length (outerlength) etc.In addition, the first lining can also be sized to the size being less than the second lining.The performance perameter such as maximum axial load-carrying capacity, maximum radial load-carrying capacity about above first lining, the second lining, the 3rd lining and the 4th lining can be selected according to embody rule occasion or actual demand.
After automobile has been installed Y type link lever rear suspension of the present invention, when back axle 7 carries out up-and-down movement in vehicle travel process, one end that main connecting rod 1 and rocking arm 3 are hinged will produce horizontal motion trend, now across back axle 7 and the rocking arm 3 be hinged thereon also can carry out side-to-side movement in this horizontal direction by ball pivot 6, thus relative disPlacement motion original between suspension and vehicle body has been changed into the hunting motion of swing arm, so just make suspension and vehicle body relative displacement therebetween almost nil, extremely successful, effectively restrain the swing of vehicle body, improve travelling comfort and the safety of suspension property and vehicle.
By carrying out measured data contrast, good technique effect achieved after specifically showing application Y type link lever rear suspension of the present invention in figures 4-7.In these diagrams, the unified symbol A or symbol B that employs indicates respectively and have employed prior art or each self-corresponding numerical curve (or histogram) of the present invention, and the arrow points shown in symbol C then indicates the optimization orientation of performance supplemental characteristic in each figure.By contrast, can clearly show about improving speed of response, improving when turning to car load allocation performance, improve the roll center of back axle to avoid turning in inclination etc., the technique effect obtained after adopting the present invention is highly significant, actv. really.
Below the automobile of illustrating Y type link lever rear suspension of the present invention in detail and having installed this Y type link lever rear suspension is only carried out by way of example, this a few example is only for principle of the present invention and embodiment thereof are described, but not limitation of the present invention, without departing from the spirit and scope of the present invention, those skilled in the art can also make various distortion and improvement.Therefore, all equivalent technical schemes all should belong to category of the present invention also by every claim of the present invention is limited.
