Definitions
- the invention relates to an actuator for automotive applications, in particular a motor vehicle door actuator, with a manual or electric motor-operated drive, further comprising a connected to the drive and acted upon by this flexible drive means, and with an actuator driven by the actuator.
- Actuators for automotive applications are known in various configurations. For example, this includes Zuziehantriebe for a motor vehicle door lock. These usually fall back on an electric motor-driven drive.
- the actuator can be used in conjunction with the lock of a closable tank filler neck.
- the drive may work manually, for example, such that a handle in the motor vehicle interior is acted upon by an operator.
- An electric motor drive is conceivable in this context.
- such actuators are used when it comes, for example, to establish a lock between a charging socket and a charging connector in an electric or hybrid vehicle and lift. Here is usually worked with an electric motor drive. Similar actuators are used, for example, to act as windows.
- an electric motor drive for the flexible drive means is usually provided.
- the driven actuator is the window to be raised and lowered.
- actuators which act in conjunction with a lock assembly for vehicle doors or vehicle doors as Notbetutzsvoriques, as described in DE 10 2013 109 912 A1.
- a handling element is provided at the end of the fingers of a user Manually attack an emergency operation and consequently ensure the manual drive.
- the prior art includes motor vehicle door actuators, as described in the also generic DE 10 2014 109 055 A1. This is about a sliding door drive with a designed as a rope flexible drive means, which is up on a groove and unwound. In addition, a guided guided on a recording guide element is provided.
- the guide element is a cable grommet.
- the rope is made as usual as a steel cable.
- the steel cables typically used in such actuators as flexible drive means with the fundamental disadvantage that they can example, corrode on long time scales.
- plastic coatings to achieve an extension of the life and at the same time to reduce the friction between the steel cable and possibly surrounding cable sheath.
- steel cables have a not negligible weight, because at this point, for example in motor vehicle door actuators and sliding door drives in particular often high forces must be transmitted from the drive to the flexible drive means. This applies, for example, with increasing wear of associated guides for the sliding door also in the case that, for example, the
- the invention is based on the technical problem of further developing an actuator for motor vehicle applications of the structure described at the outset such that, in particular, the installation space and the weight are reduced.
- a generic actuator for automotive applications in the invention is characterized in that the drive means is made predominantly of plastic.
- the invention is initially based on the recognition that plastics typically have a density in the range of about 1 g / cm 3 , whereas for steel densities in the range of about 8 g / cm 3 are observed.
- the weight of a plastic rope as a flexible drive means compared to a steel cable can be significantly reduced.
- the high flexibility of a drive means made of plastic without resulting resistance forces as they result when bending a steel cable, allows a much more compact construction option which has a very positive effect especially in a lack of space in vehicles.
- drive means made of plastic for example.
- Plastic fibers can be wound smaller than steel cables, so that the space for corresponding roles and drives can be reduced.
- the plastic high tensile strength is formed with tensile strength values of more than 1 GPa, even tensile strengths can be achieved due to the material, which at least correspond to those of alloyed steels (about 1 GPa), these usually even more or less significantly. Because the high-tensile plastic used can preferably be formed with tensile strengths of more than 2 GPa and preferably more than 3 GPa (Gigapascal).
- the plastic advantageously used at this point is generally a polymer, in particular a thermoplastic polymer and preferably polyethylene.
- plastic fibers are used at this point for the drive means. That is, the drive means is constructed predominantly of plastic fibers. This means in the context of the invention that the proportion by weight of the plastic fibers in question is more than 50 wt .-% based on the drive means.
- HPPE High Performance Polyethylene
- the fineness-related maximum tensile strength of steel is only 2 cN / dtex.
- the plastic fiber used according to the invention can have a fineness with the same tensile strength as a steel fiber, which amounts to only 10% of the steel fiber. Since the denier (in dtex) provides immediate information about the mass of the plastic fibers in question, because 1 dtex corresponds to 1 gram per 1000 meters, it follows that a steel fiber compared to the plastic fiber used in the invention has about ten times the mass.
- the weight of the flexible drive means used according to the invention can be reduced by more than 90%.
- the overall installation conditions can be optimized.
- plastic fibers have a fineness-related maximum tensile force of at least 30 cN / dtex.
- Suitable plastic fibers at this point are HPPE plastic fibers, which are known in practice under the trade name "Dyneema” and from Royal DSM NV be offered, among other things. In fact, the recourse to such plastic fibers leads to a further reduction of weight and space.
- the plastic fibers for the realization of the flexible drive means can be composed of predominantly plastic to one or more threads or plastic threads. Alternatively or additionally, the plastic fibers or the plastic threads can also be twisted together. Then one or more plastic ropes are observed.
- the flexible drive means is formed as a composite of plastic fibers as the main component and at least one secondary component. That is, the synthetic fibers are more than 50% by weight in the flexible driving means. Accordingly, the minor component can make up a maximum of less than 50% by weight of the flexible drive means.
- the invention recommends, for example, steel fibers, natural fibers, different material synthetic fibers, carbon fibers, glass fibers, etc.
- the flexible drive means may be formed, for example, as a plastic thread.
- This plastic thread may on the one hand be composed of the previously described in detail HPPE plastic fibers and on the other hand polyamide fibers as a minor constituent.
- the HPPE plastic fibers and polyamide fibers or polyamide plastic fibers can also be twisted together to form the plastic ropes.
- the polyamide fibers or polyamide plastic fibers are different in comparison to the HPPE plastic fibers material plastic fibers.
- composites of the described plastic fibers with steel fibers or even carbon fibers or glass fibers are conceivable and are encompassed according to the invention.
- a novel actuator for motor vehicle technical appli cations is provided, which essentially relies on a predominantly made of plastic drive means. Since at this point advantageously high-tensile plastic fibers are predominantly used, a significant weight reduction and at the same time a reduction in the required installation space are observed.
- a further advantage is that flexible drive means produced from predominantly plastic bring improvements in terms of their coefficients of friction compared to steel cables used in practice. That is, any abrasion at contact and bearing points is reduced, because here typically material pairings for the friction plastic: steel are observed. Associated friction coefficients are lower than friction numbers, as observed in the prior art friction steel: steel.
- the advantageously used high-tensile plastic fibers are predestined for automotive applications. Because most of the HPPE plastic fibers used at this point usually have a melting point that is well above 140 ° C. Such plastics can even be used down to minus 150 ° C, so that the entire temperature range for automotive applications of, for example, minus 60 ° C to plus 70 ° C or plus 80 ° C is easily covered.
- the high-tensile plastic fibers used are chemically resistant, especially in terms of resistance to moisture, UV rays and chemicals, as well as oils and lubricants. For this reason too, such plastics or synthetic fibers are predestined for automotive applications. Here are the main benefits.
- FIG. 1 shows an actuator according to the invention for automotive applications in the form of a motor vehicle door actuator and in particular Schiebetan drive schematically, reduced to the essential for the invention components.
- an actuator for automotive applications is shown.
- a motor vehicle door actuator and in particular a sliding door drive This has in its basic structure, first of all via a drive 1.
- the drive 1 operates according to the embodiment of an electric motor, so has in detail an electric motor, optionally in conjunction with a gear and in this case a cable drum. This is not mandatory. Because just as well, the drive 1 can work manually.
- a connected to the drive 1 and can be acted upon by this flexible drive means 2 is not acted upon by the electric motor optionally via the transmission and the cable drum, for example, in Fig. 1 train indicated, but on the drive means 2 attacking tensile forces are applied manually.
- Flierzu like the drive may be designed as, for example, Flandhabe, which is acted upon manually by an operator.
- the flexible drive means 2 is predominantly made of plastic. That is, the weight of the plastic used is the main component of the flexible drive means 2, thus making up more than 50% by weight of the drive means 2.
- the plastic used is a thermoplastic polymer.
- the plastic is formed high tensile strength, as already described in the introduction to the description.
- the flexible drive means 2 as evidenced by the sectional position in FIG. 1, consists predominantly of plastic fibers 4, 4 '.
- the plastic fibers 4, 4 ' are each combined into plastic threads 5.
- Individual plastic threads 5 are also stranded together and form in this way a total of a plastic rope 6.
- the drive means 2 may moreover have a plastic cable 6 inside receiving cable sheath 7, which covers the inner located plastic rope 6 and protects against damage.
- the cable sheath 7 acts as an abutment, similar to a cable sheath in a Bowden cable according to the prior art.
- the cable sheath 7 is a total but not mandatory and generally unnecessary.
- the plastic fibers 4, 4 ' have a fineness-related maximum tensile force of at least 20 cN / dtex and in particular a fineness-related maximum tensile force of at least 30 cN / dtex.
- the drive means 2 can also be formed as a composite of plastic fibers 4, 4 'as the main component and at least one secondary component.
- HPPE High Performance Polyethylene
- polyamide synthetic fibers 4 'as a secondary component of the flexible drive means 2 can form a composite with the HPPE plastic fibers 4.
- fibers as Maube constituent part are carbon fibers or glass fibers as well as steel fibers. This is not shown in detail.
