Description

Starting device for starting a combustion engine, as well as a drive mechanism provided with the starting device
DESCRIPTION:
Field of the invention
The invention relates to a starting device for starting a combustion engine, which starting device comprises:
- an output which can be coupled to a crankshaft of the combustion engine, as well as
- an auxiliary drive source which is connected to the output, and
- a clutch which is located between the auxiliary drive source and the output. State of the art
A drive mechanism that is provided with a starting device of this type is known from EP-A-1 486 666. In this document the auxiliary drive source is formed by a flywheel which can be coupled to the crankshaft of the combustion engine by means of the clutch and via a speed transforming gear. Furthermore, in this arrangement an electromotor is connected directly to the crankshaft of the combustion engine. The clutch is then arranged as a shift clutch that can shift a flywheel-coupled gearwheel, which forms part of the speed transforming gear, along a shaft so that this gearwheel can be moved into engagement with a further gearwheel present on the crankshaft. In this known starting device the use of the flywheel together with the clutch is to support the electromotor.
Summary of the invention
It is an object of the invention to provide a starting device of the type defined in the opening paragraph, with which the (re)start of a combustion engine can be effected in a quicker and more comfortable manner and a more cost-effective start-stop system can be realised than with the known starting device. For this purpose the starting device according to the invention is characterised in that the starting device furthermore includes a further clutch which is located between the clutch and the output This further clutch can be formed for example by a freewheel bearing that allows only a drive from the auxiliary drive source to the combustion engine and not the other way round. This is more particularly desired if the auxiliary drive source is formed by an alternator. The use of the clutch is to decouple the auxiliary drive source from the drive source once the combustion engine has been started, so that the auxiliary drive source does not rotate in unison unnecessarily or, if the auxiliary drive source is formed by a flywheel, is not braked when the combustion engine is revved down.
An embodiment of the starting device according to the invention is characterised in that a speed transforming gear is located between the auxiliary drive source and the output. This speed transforming gear is preferably located between the clutch and the further clutch. By using the speed transforming gear the number of revolutions of the combustion engine can be transferred to the auxiliary drive source in an accelerated manner and/or the torque produced by the auxiliary drive source can be transferred to the combustion engine in an intensified manner. Beyond a certain value of the number of revolutions of the combustion engine the further clutch is opened, so that the speed transforming gear need not rotate in unison over the entire range of revolutions of the engine and can be optimized for a limited range of revolutions.
By locating the speed transforming gear between the clutch and the further clutch, this speed transforming gear can be decoupled from the auxiliary drive source, which is particularly desired if the auxiliary drive source is formed by an inertia, so that it need not always allow the speed transforming gear to rotate in unison. This inertia is preferably formed by a flywheel, but may also be formed by the inertia of an alternator or starter alternator.
Preferably, a further speed transforming gear is located between the further clutch and the output, which causes the further clutch to be loaded less heavily.
In lieu of acting as a freewheel bearing, it may also be advantageous for the further clutch to be arranged as a centrifugal decoupling so as to decouple the auxiliary drive source in the form of a flywheel automatically from the combustion engine. The clutch is preferably arranged as a friction clutch.
A further embodiment of the starting device according to the invention is characterised in that the speed transforming gear is formed by a planetary gear set of which one of the rotational members is connected to the firm object. The firm object is for example a transmission housing or an engine block. Preferably, in that case the clutch is then located between said rotational member and the firm object and this clutch is formed by a friction brake. In lieu of being arranged as an alternator it may also be advantageous to arrange the auxiliary drive source as a starter alternator. A starter alternator in this respect is meant to be understood as an electromotor generator, which is a generator that can also act as an electromotor.
A still further embodiment of the starting device according to the invention is characterised in mat the starting device further includes an auxiliary electromotor which is connected to the auxiliary drive source. If the auxiliary drive source is formed by a flywheel, it can be maintained at the right revolutions per minute or be revved up.
The invention likewise relates to a drive mechanism comprising a combustion engine that includes a crankshaft, as well as a starting device according to the invention. With respect to the drive mechanism the invention is characterised in that the output is connected directly to the crankshaft of the combustion engine.
An embodiment of the drive mechanism according to the invention is characterised in that a pulley is located on a first end of the crankshaft, which pulley drives accessories via a belt or chain transmission and can be coupled with the other, second end of the crankshaft to a transmission of a vehicle, while the output of the starting device is connected to the first end of the crankshaft.
The invention furthermore relates to a drive mechanism comprising a combustion engine that includes a crankshaft, as well as a belt or chain transmission with a first pulley, which is located on a first end of the crankshaft, and a second pulley which drives accessories, which crankshaft with the other, second end can be coupled to a transmission, which drive mechanism further includes a starting device according to the invention. With respect to this drive mechanism the invention is characterised in that the output of the starting device is connected directly to the second pulley.
Brief description of the drawing figures
The invention will be further described below in more detail with reference to a diagrammatic representation of examples of embodiment of the drive mechanism according to the invention given in drawing figures, in which:
Fig. 1 shows a first embodiment of the drive mechanism according to the invention where the output of the starting device is connected directly to the crankshaft;
Fig. 2 shows a second embodiment of the drive mechanism according to the invention where the clutch is arranged as a friction brake; and Fig. 3 shows a third embodiment of the drive mechanism according to invention where the output is connected to the crankshaft by means of a belt transmission.
Detailed description of the drawing figures
Fig. 1 shows a first embodiment of the drive mechanism according to the invention. The drive mechanism comprises a combustion engine 1 that includes a crankshaft 3 with a first pulley 5 of a belt transmission 7 on a first end 3 a of the crankshaft 3 and a flywheel 9 on the other, second end 3b. When used in a vehicle this second end 3b of the crankshaft is connected to a transmission and the belt transmission 7 drives accessories of the vehicle such as, for example, a generator.
The drive mechanism further includes a starting device 11 for starting the combustion engine I. The starting device 11 has an output 13 which is connected directly to the first end 3a of the crankshaft 3. The starting device comprises an auxiliary drive source, which is formed by a flywheel 15, which is connected to the output.
Between the flywheel 15 and the output 13 there are located a clutch 17 and a further clutch 19 which are arranged as a friction clutch or freewheel bearing respectively. A speed transforming gear 21 is located between the two clutches. This speed transforming gear is arranged as a planetary gear set 23 of which one of the rotational members 25 is connected to the firm object 27. This firm object is formed, for example, by the chassis of a vehicle or a housing of a transmission.
The starting device 11 further includes an auxiliary electromotor 29 which is connected to the flywheel 15 to maintain same at the right number of revolutions, or to rev it up if necessary.
Fig. 2 shows a second embodiment of the drive mechanism according to the invention. All component parts shown in Fig. 2 which are similar to those of the first embodiment carry like reference numerals. In this drive mechanism the clutch 33 of the starting device is formed by a friction brake which is connected, on the one hand, to said rotational member 25 and, on the other hand, to the firm object 27.
Fig. 3 shows a third embodiment of the drive mechanism according to the invention. All component parts shown in Fig. 3 which are similar to those of the first embodiment carry like reference numerals. In this drive mechanism the starting device 35 is not connected directly to the crankshaft 3 of the combustion engine 1 but to a second pulley 37 of the belt transmission 7. In this starting device 35 the inertia of an alternator 39 acts as an auxiliary drive source. This alternator 39 is connected to the second pulley 37 by means of a freewheel bearing 41. In parallel with this freewheel bearing 41 are arranged the clutch 17 and the further clutch 19 with the speed transforming gear 21 in between. The further clutch 19 is formed in this case by a centrifugal decoupling that opens up beyond a specific number of revolutions. Here too an auxiliary electromotor 29 is connected to the auxiliary drive source to maintain same at the right number of revolutions or rev it up.
Albeit the invention has been described in the foregoing with reference to the drawing figure, it should be observed that the invention is not by any manner or means restricted to the embodiment shown in the drawing figure. The invention also extends to all embodiments deviating from the embodiment shown in the drawing figure within the spirit and scope defined by the claims.
For example, in the third embodiment the auxiliary electromotor may be omitted while the auxiliary electromotor is then maintained at the right number of revolutions or revved up by the alternator itself. In lieu of an alternator the auxiliary drive source may also be arranged as a starter alternator.
Furthermore, in lieu of a planetary gear set may be used any conceivable speed transforming gear, such as, for example, a notched belt transmission, a gear transmission, a friction transmission, a belt or chain transmission or a combination of one or more of these transmissions.
Alternatively, the belt transmission 7 of the embodiment shown in Fig. 3may form part of the starting device 35 and form therein a further speed transforming gear which is located between the further clutch 19 and the output. In that case the output is formed by the shaft of the first pulley 5.
