  • Publication number: 20130247858
    Abstract: A combustion engine can be started by means of a starting device. During the starting operation attendant with the starting device driving the vehicle this drive is also effected by energizing a clutch which connects the combustion engine via a transmission to the wheels L of the vehicle. By utilizing the starting device for the starting operation also for meanwhile driving the vehicle and/or accelerating same, a faster and/or more gradual drive/acceleration of the vehicle is realized.

  • Publication number: 20120316022
    Abstract: A transmission system comprises two transmission modules which are arranged in series, an output shaft of the first transmission module being connected via a mount point to an input shaft of the second transmission module. The transmission system further includes an electromotor which is connected to the mount point. The first transmission module is formed by a two-step reduction mechanism and comprises a planetary gear set with at least three rotational members one of which is connected to a brake. The first transmission module further includes a short-circuit clutch which is positioned between the other two rotational members. The brake may be used for launching the vehicle.

  • Publication number: 20120142479
    Abstract: A transmission module 1 has an input 3 which can be connected to a drive source, and an output 5 which can be connected to a differential. The transmission module 1 further has a clutch 7 and an epicyclic gearing 21 with three rotational members, of which a first rotational member 23 is connected to the clutch housing 9, a second rotational member 25 is connected to a brake 27 and a third rotational member 29 is coupled to the output 5. A transmission 31 also forms part of the transmission module 1. Between the clutch 7 and the epicyclic gearing 21 is located a partition 45 which is connected to the transmission housing 33 while a wet space 47 is formed between the partition and the transmission housing. The actuation cylinder 15 of the clutch, the operating cylinders 48 of the brake 27, as well as the oil pipes leading to it are fixed to the partition 45 as a result of which the actuation is arranged as a single module.

  • Publication number: 20120090569
    Abstract: A drive mechanism 1 comprises a combustion engine 3 and a start system 5 which has an output 7 that is connected to a camshaft 9 of the combustion engine. The start system further includes a flywheel 11 and connecting means connecting the flywheel to the output. The connecting means comprise a clutch 13 and a gear reduction 15. The start system 5 further includes a drive source 17 formed by an electromotor which is directly connected to the flywheel 11 or which is connected to the connecting means between the clutch 13 and the flywheel 11. The maximum power that can be delivered by the drive source 17 is just sufficient to maintain the flywheel at the proper r.p.m. If the drive source 17 is turned on, it thus delivers just sufficient power to maintain the flywheel at the proper r.p.m. The maximum power of the drive source is in this case 50 W.

  • Publication number: 20120058852
    Abstract: A transmission which is pre-eminently suitable for an electric and/or hybrid drive has an input which can be connected to an electromotor/generator, and an output which can be connected to a load. The transmission has two parallel transmission paths between the input and output, first coupling means being present in the first transmission path and second coupling means being present in the second transmission path. Furthermore, a gear reduction is present in at least either of the two transmission paths. The first coupling means are arranged such that they are not capable of dissipating significant power and the second coupling means are arranged such that they are capable indeed of dissipating significant power.

  • Publication number: 20120028752
    Abstract: A flywheel module comprises a coupling unit which has an input shaft and an output shaft. This coupling unit has a first coupling of which a first coupling half can be connected to a combustion engine and a second coupling half can be connected to a continuously variable transmission. The flywheel module further comprises a flywheel unit which has an in/output and is formed by a flywheel and a reduction gear unit connected to the flywheel. This flywheel unit is exclusively connected to the in/output via the coupling unit.

  • Publication number: 20110281681
    Abstract: A driving mechanism has a drive source which is coupled via a clutch to an oil lubricated transmission, and a transmission module which is present parallel to the transmission. The transmission module has a planetary gearing of which a first rotational member is bearing supported on an insert sleeve attached to an operating cylinder for the clutch and is connected to a connecting plate which is attached to a first clutch portion of the clutch. A second rotational member is connected to a connecting gear. A third rotational member is formed by a ring gear which has side guards maintain grease inside the planetary set of gears.

  • Publication number: 20110271790
    Abstract: A flywheel module has a flywheel as well as a speed transforming device which has a first in/output which is connected to the flywheel, and a second in/output which is coupled to a drive line of a vehicle. The speed transforming device has a bypass speed transforming device and a motor and/or generator. Energy can then be exchanged with the flywheel by suitably controlling the motor and/or generator. As a result of the delivery of a negative torque by the motor and/or generator, the flywheel accelerates and because of the delivery of a positive torque by the motor and/or generator the flywheel decelerates.

  • Patent number: 7824294
    Abstract: A vehicle comprises a drive source that drives the wheels via a transmission system. The transmission system has an epicyclic gearing with three rotational members a first rotational member connected to the drive source, a second rotational member connected to the wheels via a first reduction and a final reduction and a third rotational member connected to a brake. The brake constitutes reaction means for balancing torque. The transmission system also includes a transmission parallel to the epicyclic gearing and a transmission in series with the epicyclic gearing. Moreover, the transmission system has a lock-up clutch capable of connecting the first rotational member to the second rotational member. This transmission system enables shifting between various transmission ratios without torque interruption, using only one brake. The transmission in series with the epicyclic gearing can directly be connected to the load via the lock-up clutch or via the ‘braked ’ planetary set.

  • Patent number: 7765887
    Abstract: A drive has a drive source and a continuously variable transmission, with an outgoing shaft having a first gear wheel. A clutch is present between the drive source and the ingoing shaft. The outgoing shaft of the transmission is connected to a gear wheel connected to a differential via a drive line for driving forwards. The drive line has an intermediate shaft with thereon a second gear wheel, which is interlocked with the first gear wheel and the third gear wheel, which is interlocked with the gear wheel. For reversing, the drive line can be interrupted by means of a disengagement and the drive is provided with a further drive line between the gear wheel that is connected to the differential and the outgoing shaft of the transmission.
