Abstract:
A flywheel module (1) has a closed housing (3) with an opening, and an output (5) which is formed by an output shaft (6) that extends outward through the opening. A sealing ring (7) is present between the output shaft and the boundary wall of the opening. A flywheel (9) is accommodated in the housing (3), which flywheel is connected via a clutch (11) to a first gear of a transmission (13) whose other gear is connected to a first portion (15A) of a centrifugal disengaging clutch (15) of which the other portion (15B) is connected to the output shaft (6). With this it be avoided that the flywheel starts to run at too high a speed, which guarantees the safety of the flywheel module.
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.
Abstract:
A transmission 1 which is pre-eminently suitable for an electric and/or hybrid drive has an input 3 which can be connected to an electromotor/generator 5, and an output 7 which can be connected to a load 9. The transmission 1 has two parallel transmission paths 11, 13 between the input and output, first coupling means 15 being present in the first transmission path 11 and second coupling means 17 being present in the second transmission path 13. Furthermore, a gear reduction is present in at least either of the two transmission paths. The first coupling means 15 are arranged such that they are not capable of dissipating significant power and the second coupling means 17 are arranged such that they are capable indeed of dissipating significant power.
Abstract:
A gear changing device (1) has a gear lever (3) to operate a vehicle gear box, and several sensors to detect the movement of the gear lever with respect to the surroundings as a result of a force exerted by a user on the gear lever. The gear-changing device also has two electrical motors (5, 7), which are connected to the gear lever (3) via transmissions (9, 11). The transmission (9, 11) are formed by self-braking worm-worm wheel transmissions. The gear lever (3) can only be shifted if the electrical motors are actuated. The electrical motors shift the gear lever or permit the movement of the gear lever, depending on the sensor signals. The movement speed of the gear lever in this is such that it appears to the user that he has to overcome resistance to be able to shift the gear lever, so that the gear lever exercises a haptic effect.
Abstract:
A drive (1) has a drive source (3) and an automatic manual gearbox (5) connected to it. There is a friction clutch (7) between the drive source and the gearbox. The drive also has a differential (11), which with a gear wheel (13) engages a first gear wheel (17) on the gearbox output shaft (15), as well as a gear module (19) to change the transmission in the gear without interrupting the drive. The gear module (19) has a brake (25) and a bypass transmission (27) with three rotation bodies (29, 31, 33), of which a first rotation body (29) is connected to the first clutch part (7a), a second rotation body (31) is connected to a connecting gear wheel (35), which engages the first gear wheel (17), and the third rotation body (33) is connected to the brake (25). The connections of the rotation bodies (29, 31, 33) to the parts stated (7a, 35 and 25) respectively of the drive are made in this as splines S 1 , S 2 and S 3 respectively.
Abstract:
A vehicle 21 comprises a drive source E that drives a load L via a transmission system T 2 . The transmission system T 2 has an input shaft a in that is connected to the drive source B and an output shaft a out that is connected to the load L. The transmission system T 2 furthermore comprises and epicyclic gearing P and, in series with that, a continously variable transmission A. The epicyclic gearing P is a planetary gear set of which a first rotational member a is connected to the input shaft a in , a second rotational member c is connected to the output shaft a out , and a third rotational member s is connected to a brake B and furthermore to a flywheel F that enables additional torque balancing. To this end, the flywheel F can be connected to the third rotational member a via an inertia-clutch C 1 , or to the first rotational member a via a further inertia-clutch C 2 . To enable reverse driving using this transmission system T 2 , without the need for a dedicated gear stage in the transmission A, the third rotational member a can be connected to the drive source B via a reduction R and a reduction-clutch C 3 .
Abstract:
A drive system (103) has a driven shaft (107), a driving shaft (105) and a flywheel (119) both of which can be connected to the driven shaft (107) through a clutch (117). The drive system (103) furthermore has a continuously variable transmission (125) located between the flywheel (119) and the clutch (117). The driving shaft (105) can drive the flywheel (119) through the continuously variable transmission (125). A further clutch (123) is positioned between the continuously variable transmission (125) and the flywheel (119), to enable disengaging the flywheel (119) from the rest of the drive system. Further, an epicyclical gearing (131) is applied between the clutch (117) and the further clutch (123). This way, only one CVT with a smaller ratio coverage suffices.
