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.

This coupling unit (11) has a first coupling (23) of which a first coupling half (25) can be connected to a combustion engine (3) and a second coupling half (27) can be connected to a continuously variable transmission (7). The flywheel module (9) further comprises a flywheel unit (13) which has an in/output (28) and is formed by a flywheel (29) and a reduction gear unit (31) connected to the flywheel (29). This flywheel unit (13) is exclusively connected to the in/output (28) via the coupling unit (11).
Abstract:
A start system 31 for a combustion engine 39 comprises a first auxiliary drive source which is constituted by an electromotor 33, as well as a second auxiliary drive source which is constituted by a flywheel 41, and a clutch 35 which is capable of coupling one of the auxiliary drive sources 33, 41 to a crankshaft 37 of the combustion engine. The system 31 includes a further clutch 43 which can couple the two auxiliary drive sources 33, 41 together. As a result, the flywheel 41 can be revved up by means of the electromotor 33 prior to the combustion engine 39 being started, thus while there is no coupling yet to the crankshaft 37. When, subsequently, the combustion engine 39 is started, the pre-rewed flywheel 41 is coupled to the crankshaft 37 with the flywheel 41 delivering additional torque.
Abstract:
A vehicle (1) has an internal combustion engine (3), a pair of wheels that are to be driven (5), and a drive (7) by means of which the internal combustion engine is connected to the pair of wheels that are to be driven. The drive (7) has two drivelines (9, 11) parallel to each other situated between the internal combustion engine and the pair of wheels that are to be driven, of which the first driveline (9) can be disengaged and of which the second driveline (11) may or may not transmit torque. Furthermore, the drive (7) has a control unit (13), which is such that for starting the internal combustion engine, it disengages the first driveline (9) and sets the second driveline (11) so that it can transmit torque to the internal combustion engine, in such a way that by this second driveline no reactive torque is delivered to the wheels (5) as a result of which the vehicle would be driven forward.

The switchable valve (91) is operated such that the line pressure produced by the oil pump can be made lower or higher than the pressure in the main line (73).
Abstract:
A combustion engine E can be started by means of a starting device 9. During the starting operation attendant with the starting device 9 driving the vehicle 1 this driving is also effected by energizing a clutch C2 which connects the combustion engine E via a transmission T 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.

Abstract:
A driving mechanism Dl comprises a drive source E which is connected by means of a clutch CO to a transmission T which is connected to wheels L of the vehicle. The driving mechanism Dl further includes two hybrid modules of which a first module Ml is connected to the drive source E and the second module M2 is connected between the transmission T and the wheels L to the drive line. The first hybrid module Ml comprises a flywheel Fl and a flywheel clutch CI and the second hybrid module M2 comprises a motor/generator M/G and a further clutch C2. By providing the drive line with a specific combination of two hybrid modules which can function both individually and in conjunction with each other, higher efficiency of the drive line can be achieved. Furthermore, the specific combination of hybrid modules is advantageous in that the requirements made on the individual modules are less stringent causing the overall cost of the drive line to be lower.
Abstract:
A drive mechanism comprises a transmission I as well as an electromotor/generator 5. The transmission 1 is connected via an input 11 to the electromotor/generator and via an output 13 to the wheels 3. The transmission 1 has two planetary gear sets 19 and 27 having three rotational members each, of which first rotational members 21 and 29 are connected to the input, second rotational members 23 and 31 are connected to the output and third rotational members 25 and 33 are connected to a first and second brake 35 and 37 respectively. By actuating either of the brakes 35 and 37 a speed transforming gear is created between the input and the output. By actuating one brake during the releasing of the other brake, it is possible to switch between the two speed transforming gears without an interruption of the torque transfer from the electromotor/generator 5 to the load 3 or vice versa.
