Description
Technical field
The present invention relates to the multi link rear wheel suspensions for motor vehicles, and it includes left wheel frame and right wheel carrier, the left sides
Each of wheel carrier and right wheel carrier are guided by multiple individual connecting rods, and multiple individual connecting rod includes being coupled in car body one
The spring link of side or wheel carrier side.
Background technology
It is used for driven rear wheel and non-driven trailing wheel, such as patent known to the multi link rear wheel suspension of the type
Described by EP1609631A1.
Multi link rear wheel suspension has more profitabilities in terms of driving dynamics than simple torsion girder-like rear wheel suspension
Can, this is because wheel can be compressed and can be sprung back totally independently of one another, but multi link rear wheel suspension produces
Come it is more complicated, since it is desired that more individual components, tightening member and to the fastening point on car body or its subframe.
Invention content
The purpose of the present invention is to provide one kind to spend in production and installation less and in terms of driving dynamics
Performance do not have lossy multi link rear wheel suspension.
According to the present invention, the purpose including the multi link rear wheel suspension of following technical characteristic by realizing.In addition, this hair
The bright favourable improvement for additionally providing the present invention.
A kind of multi link rear wheel suspension for motor vehicles includes individually to connect rod-guided left wheel each by multiple
Frame and right wheel carrier, multiple independent connecting rod include the spring link for being couple to car body side or wheel carrier side, two of which
The spring link of wheel carrier is couple to car body or its subframe by sharing tightening member.
Further, shared tightening member is designed to integral component, and two spring links can pivotally coupling independently of one another
It is connected on the component, and the component itself is fastened in the fastening point of car body or subframe.
Further, rear wheel suspension is intended to be designed to passenger car.
Further, passenger car has non-driven trailing wheel or driven rear wheel.
Further, the independent connecting rod of each wheel carrier includes spring link, longitudinal rod, drag link and tilting bar.
Further, rear wheel suspension is double leval jib rear wheel suspension.
Further, the independent connecting rod of each wheel carrier is spring link, longitudinal rod, drag link and tilting bar.
Further, the independent connecting rod of each wheel carrier is couple to car body side or wheel carrier side by bushing bearing.
Further, longitudinal rod is fixedly connected on corresponding wheel carrier, and/or the company of being designed to control
Bar.
According to the present invention, the spring link of two wheel carriers is by means of shared tightening member --- rather than as existing skill
Like that in each case all by means of individual tightening member in art --- it is couple to car body, or is preferably couple to secondary vehicle
On frame, which is the transverse link of other bearing spring, and the spring itself is then supported on car body, and is had or not
With damper.Therefore, a tightening member is not only saved, and reduces mounting cost.In addition, car body or subframe must
The position that must be designed for linkage connector and accordingly reinforce reduces one.Therefore car body weight can also mitigate.It is all this
A little is especially especially beneficial in the case where mass production is with self-supporting car body passenger car.
In a preferred embodiment of the invention, the independent connecting rod of each wheel carrier includes spring link, longitudinal rod, cross
Pull rod and tilting bar.However, these independent connecting rods may also include different names and/or in terms of design or function it is similar
And/or additional connecting element.For example, for driven rear wheel, every side can there are one additional connecting rods.
In the case where multi link rear wheel suspension is double leval jib rear wheel suspension, the independent connecting rod of each rear wheel frame is preferably
Spring link, longitudinal rod, drag link and tilting bar.
Independent connecting rod preferably passes through bushing bearing in car body side or in wheel carrier side by convention --- namely
Pass through bushing-screwed joint in each case --- it is couple to car body or subframe, the bushing welding of the bushing-screwed joint
On to connecting rod and its bolt is fastened on wheel carrier or car body or subframe, wherein can have rubber between bushing and bolt
The intermediate space of glue material filling in order to provide a degree of connector flexibility and is used for damping vibration.Therefore, shared
Tightening member can be designed as such as bushing with multiple bushings-screwed joint type.
In multi link controls connecting rod rear wheel suspension preferred embodiment, all connecting rods in addition to longitudinal rod are all coupled in
Car body side and wheel carrier side.In the present embodiment, longitudinal rod is designed to control connecting rod and is only coupled in car body
Side, but they are fixedly attached to from wheel carrier side on respective wheel carrier.
Description of the drawings
Exemplary embodiment describes with reference to the accompanying drawings as follows：
Fig. 1 shows the schematic diagrames of the controls connecting rod suspension of two trailing wheels of passenger car.
Specific implementation mode
The controls connecting rod rear wheel suspension only briefly showed includes left wheel frame 1a and right wheel carrier 1b, left wheel frame 1a and the right side
Wheel carrier 1b is couple to car body via longitudinal rod 2a and 2b by means of bushing bearing 3a and 3b respectively（It is not shown in figure）, longitudinal
Connecting rod 2a and 2b are designed to control connecting rod.Longitudinal rod 2a and 2b are fixedly joined on respective wheel carrier 1a and 1b.
In addition, each wheel carrier 1a and 1b is couple to the subframe 4 of car body by other connecting rod, i.e., in varied situations
Be couple to the subframe 4 of car body by spring link 5a or 5b, drag link 6a or 6b and tilting bar 7a or 7b, tilting bar 7a or
7b can be longer than drag link 6a and 6b.
Each drag link 6a and 6b is couple to wheel carrier 1a or 1b by bushing bearing 8a or 8b, and passes through bushing bearing
9a or 9b is couple to subframe 4.
Each tilting bar 7a and 7b is couple to wheel carrier 1a or 1b by bushing bearing 10a or 10b, and passes through bushing axis
It holds 11a or 11b and is couple to subframe 4.
Each wheel carrier 1a and 1b are also couple to car body by damper 12a or 12b.
Each spring link 5a and 5b is supported by helical spring 13a or 13b, and helical spring 13a or 13b itself is then by vehicle
Body（It is not shown）It is supported.Selectively, damper 12a and 12b can also be respectively set in helical spring 13a and 13b.
Each spring link 5a and 5b is couple to wheel carrier 1a or 1b, and two springs by bushing bearing 14a or 14b
Connecting rod 5a and 5b is by shared integrated fastening elements 15 as follows in the center position coupling of motor vehicles longitudinal direction
It is connected to subframe 4, that is, in such a way that two spring links 5a and 5b can be pivotally coupled on subframe 4 independently of one another, wherein
The shared integrated fastening elements 15 equally can be the type of bearing insert.Based on this purpose, spring link 5a and 5b must
Need be relatively long, but this is best for above-described multi link controls connecting rod rear wheel suspension, is especially being realized
In terms of large transmission ratio between camber of spring and wheel travel.
Shared integrated fastening elements 15 can be similar to the simple hinge for furniture of such as strap bolt, and wherein bolt can be with
It is fastened onto on subframe 2.
