Definitions
- the invention relates to a generator of a motor vehicle according to the preamble of claim 1.
- Drives for a generator of a motor vehicle are known.
- the drive element the crankshaft of the internal combustion engine for the generator of the motor vehicle on which a pulley is arranged.
- a pulley is also attached to the generator. Both pulleys are from a belt entwined so that the drive of the generator directly via the crankshaft of the internal combustion engine is possible.
- a switchable gearbox it is already suggested between the crankshaft and the generator to arrange a switchable gearbox.
- Such Multi-step transmission for example planetary gear, are particularly popular with so-called starter generators used.
- the drive according to the invention for a generator with the features mentioned in claim 1 is characterized in that the generator on one narrow speed range can be designed as it with the continuously adjustable speed transmission unit is possible, regardless of the speed the drive element for the generator, a almost constant speed for the active part, in particular to provide the rotor of the generator. It is therefore advantageously achieved that the generator over large speed ranges of the drive element are driven at constant speed can. In particular, this makes it possible to move the Components of the generator to a lesser To design maximum speed. So it is advantageously possible, the nominal speed of the generator both at idle speed and at maximum Provide the speed of the drive element.
- An embodiment is particularly preferred the continuously adjustable speed transmission unit, which a drive member and an output member has between which the slip is adjustable is. So you can easily and Way the stepless adjustability of the speed translation unit realize.
- the drive member and the driven member are more preferred Embodiment part of a viscosity coupling, in which is known in itself Way the drive and the output member in one turn the liquid medium, adjusting the Slip can be provided that the distance between the drive member and the driven member and / or the medium amount or the medium pressure is changeable to different speed ratios to be able to realize.
- a Speed translation unit can be provided works like a speed converter.
- Speed converters are, for example, from automatic transmissions known and have at least one turbine wheel and an impeller. Depending on the degree of medium filling of the converter can thus the speed ratio can be set.
- the output speed is particularly preferred Speed translation unit selected constant, see above that the generator is constant at its rated speed can be driven.
- a regulation is provided, the mechanical and / or electrical and / or can work hydraulically.
- a mechanical scheme can, for example, by a governor or the like.
- An electric one Control works in a preferred embodiment with an electric speed sensor.
- the drive member of the speed transmission unit is preferred via a belt drive with the Drive element connected. Therefore, the in Belt drives known in the art are used become. So it is only the invention Speed translation unit between generator and belt drive switched.
- the drive element the crankshaft of the internal combustion engine Motor vehicle is.
- the crankshaft has different Speeds up.
- stepless speed transmission means it is however possible the generator at constant speed to drive.
- the invention is described below using an exemplary embodiment with reference to the only figure closer explained.
- the figure shows a speed translation unit, a generator on the output side is coupled.
- a drive 1 for a generator 2 can be seen from the figure.
- a drive element 3, which is for example the crankshaft 4 of an internal combustion engine 5, can be assigned to the drive 1.
- the drive 1 comprises a continuously variable speed ratio unit 6 that drivingly connected to the drive member 3 and therefore with the drive speed n to be acted upon is.
- the speed translation means 6 is connected to the generator 2, which is thus driven with the output speed n ab .
- a control device 7 In order to drive the generator 2 at a constant speed, a control device 7 is provided, which adjusts the output speed n from the speed transmission unit 6 accordingly via the speed transmission ratio of the speed transmission unit 6 in order to be able to provide the aforementioned constant drive speed for the generator 2.
- the control device 7 has a speed sensor 8 for detecting the output speed n ab .
- the setting is made of the speed ratio mechanical and / or electrical and / or hydraulic.
- the speed translation unit 6 with a driving member 9 and a driven member 10 is provided, between which the slip is adjustable by means of the control means 7 in order at different drive speeds n n at a constant output speed from being able to deploy.
- the speed transmission unit 6 is designed as a viscosity clutch 11, in which the drive member 9 is realized by a drive disk 12 and the output member 10 by a driven disk 13.
- the drive and driven pulleys 12 and 13 are arranged in a medium container 14 which can be filled with different amounts of a liquid medium in order to adjust the speed ratio. It can also be provided that the distance between the drive pulley 12 and the driven pulley 13 is adjusted in order to be able to set the speed transmission ratio.
- the control device 7 therefore takes over the control of the disk spacing and / or the filling quantity of the medium container 14.
- a belt drive is provided which drives the drive element 9.
- the drive member 9 directly with the Connect crankshaft 4.
- the speed translation unit 6 is as shown as a viscosity clutch 11 or as a speed converter (not shown) trained, still result the following advantages: the noise development in the invention Drive 1 is opposite one Stepped gearbox low. In addition, the speed translation unit works 6 wear-free because both with a viscosity coupling as well as with a Speed converter no direct mechanical connection between drive member 9 and output member 10 is present.
- control device 7 it is also possible the rotational irregularity in particular changing load conditions or speed ratios to dampen the drive element 3. It can also be in a particularly preferred Operating position of the generator 2 from the drive element 3 are disconnected so that when the No internal combustion engine 5 for the generator Drag torques must be applied. In the Viscosity clutch 11 can do this, for example can be realized that the medium container 14th is almost completely emptied. However, it can also be provided that the distance between the Drive member 9 and the output member 10 as large is selected that no torque transmission takes place.
- Speed translation unit an optimization of the Design of generator 2 with regard to power, Noise, weight and cost can be made because of it designed for a relatively narrow speed range can be. It is also advantageous that of the Drive element 3 only requires the power is that the generator 2 to cover the current electrical power requirement also needed. Overall, the efficiency of the internal combustion engine could thus 5 can be improved.
