Description
Technical field
The present invention relates to the protection pipes for motor vehicle damper of preamble according to claim 1.
Background technique
Such as such protection pipe as known to 2,007 079 911 A1 of WO.The protection pipe surrounds machine along circumferential direction
It motor-car damper and prevents motor vehicle damper by external action, such as is hit by stone.Protection pipe includes fixation kit,
The fixing component for being for example embodied as so-called fix eyelet of itself and motor vehicle damper forms shape and is cooperatively connected and therefore
It is axially fixed at motor vehicle damper.
Structure design based on such protection pipe, the protection pipe only can be assemblied in motor vehicle in piston rod protruding side
On damper.However, the assembly method can be pretty troublesome in this case, and therefore same cost is very high, because of protection pipe
Being assemblied at damper must be executed immediately after painting as the first step.Equally, the replacement of protection pipe is pretty troublesome, because
For damper can must be dismantled completely thus before the impaired protection pipe of replacement, and removes and be mounted in piston rod protruding side
Which increase the time of replacement process and therefore all components on motor vehicle damper increase cost.
Summary of the invention
Based on situation described above, the purpose of the present invention is to provide a kind of protection pipe for motor vehicle damper,
It can be assemblied at motor vehicle damper afterwards in a manner of simple.
The purpose is realized by the protection pipe of the feature of the characteristic with claim 1.Other advantageous embodiment party
Case variant is illustrated in the dependent claims.
According to the first advantageous embodiment variant, matrix is so shaped, that is, it is transversal with substantially long hole shape
Face, wherein the longest of fixing component that the length of long hole is greater than motor vehicle damper radially extends.Protection pipe can edge as a result,
It is axial to be fixed on motor vehicle on the tube-shaped tube that fixing component side shifts motor vehicle damper onto, and followed by fixation kit
At the fixing component of damper.Here, fixing component pass through entire protection pipe and then with the fixation kit shape of protection pipe
It is cooperatively connected.
According to another advantageous design scheme, matrix includes the profile that reclines projected radially inward, in installation condition
In be radially supported at the tube-shaped tube of damper.Thus the protection pipe being assemblied at motor vehicle damper is effectively inhibited
Undesirable radial motion.
It in order to mitigate weight, can be provided according to another advantageous example, matrix include leaving a blank of extending in longitudinal section
Portion is limited by the first closed-loop along axial in side, and is limited by the second closed-loop along axial in the other side, wherein the
One closed-loop is implemented at the end section towards fixation kit, and the second closed-loop is implemented in the end back to fixation kit
At section.Closed-loop assigns the additional stability of protection pipe and equally provides the profile that reclines, and is used to make protection pipe radially
It is supported at the tube-shaped tube of motor vehicle damper.
In addition, can advantageously provide for, the second closed-loop of matrix has guide surface, to subtract for axially guiding motor vehicle
The piston rod protection pipe of vibration device.At the radially supporting inner wall to piston rod protection pipe of guide surface, piston rod protection is thus prevented
Pipe contacts tube-shaped tube and damages the corrosion-inhibiting coating on tube-shaped tube.
If matrix is made of at least two base members, wherein base member can be connected to each other, such as another advantageous
As illustrating in embodiment variant, protection pipe radially, i.e. can be assemblied in motor vehicle vibration damping along lateral in a simple manner
At device.Motor vehicle damper need not be dismantled when replacing protection pipe at motor vehicle as a result,.At this point, base member can be very simple
Ground guides motor vehicle damper into from side, and then shape-ordinatedly and/or force transmitted and/or material mating connect each other
It connects.Connection can also be realized according to another advantageous example by locking structure, can directly dispose, shape or be moulded at least one
At a base member, or it is embodied as additional individual component.
Another advantageous embodiment variant regulation of protection pipe according to the present invention, base member are thin by least one
Film hinge is connected to each other.Because thus protection pipe is opened wide in side and is coupled in the other side by least one film hinge,
So the embodiment variant is equally particularly well-suited for protection pipe from side assembly on motor vehicle damper.

It includes the profile 11 that reclines that Fig. 1, which all shows protection pipe 2 according to the present invention into Fig. 8, is radially propped up in the state of assembly
Support is at tube-shaped tube, to prevent the radial movement for the protection pipe 2 being assemblied at the tube-shaped tube 3 of motor vehicle damper 1.
As Fig. 4, Fig. 5 and it is shown in Fig. 6, protection pipe 2 according to the present invention may include the portion of leaving a blank 12, limit
It is axially extended in fixed longitudinal section 23.Portion 12 of leaving a blank is limited by the first closed-loop 13 and the second closed-loop 14 along axial direction,
And it is limited by the axially extending ratio of the axially extending and closed-loop of protection pipe 2 13,14.Here, the first closed-loop
13 implement at the first end 15 of the close fixation kit 7 of protection pipe 2, wherein the second closed-loop 14 is implemented in protection pipe 2
At and the second end 16 set axially opposed with fixation kit 7.Guide surface 17 is formed at the second closed-loop 14, is such as schemed
It is radially supported at as being illustrated in 4 at the inner wall of piston rod protection pipe 18 and is used as piston rod protection pipe 18
Guide portion.Thus prevent piston rod protection pipe 18 from radially colliding due to the open section in the portion of leaving a blank 12, that is, tube-shaped tube 3 is not
The section protected, and etch-proof coating of the injury protection pipe 2 in the section.
Fig. 7 and 8 show protection pipe 2 can also multi-piece type, especially implement in two style.As shown in figures 7 and 8
Like that, the protection pipe that two-piece type is implemented includes the first base member 19 and the second base member 20, they can half hull shape or half
Implement tubularly and is connected to each other.
Fig. 7 shows an embodiment variant, and the first base member 19 and the second base member 20 are by locking knot accordingly
Structure 21 is connected to each other, wherein and locking structure 21 is shown as two connection rings 30 in the embodiment variant shown in Fig. 7, point
It is not joined to and implements in the notch at each base member 19,20 in end side respectively, and therefore by two and half tubular bases
Body component 19,20 connects into entire protection pipe 2.
Fig. 8 shows another embodiment variant comprising film hinge 22.Film hinge is that the ratio of protection pipe 2 is protected
The section that the rest part of pipe 2 more unfertile land is implemented, the section extend axially through entire protection pipe 2 and by the first matrix structures
Part 19 is connected with the second base member 20.Film hinge keeps flexible so that two base members 19,20 can with film
The side that is diametrically opposite and setting of hinge 22 is separated from each other, to be assembled in the side of tube-shaped tube 3.In addition, according to this hair
Bright protection pipe 2 includes the locking structure 21 for being embodied as clamping lock connection according to the embodiment variant shown in Fig. 8, is designed to
Two base members 19,20 are made shape-ordinatedly to be connected to each other.In addition to matching for the shape explained above of base member 19,20
It closes except the connection scheme variant with power transmission, provides according to the present invention, two base members 19,20 equally can be borrowed to material mating
Help adhesives or thermal connection.
