  • Patent number: 10625784
    Abstract: A vehicle comprising: at least one electric motor configured for driving the vehicle; a battery pack configured to supply the electric motor with electric power for driving the vehicle; a vehicle body frame structure configured to form a main supporting structure of the vehicle; and a collision energy absorbing system configured to absorb collision energy in the event of an accident. The collision energy absorbing system comprises a first absorbing structure that is positioned between the battery pack and a front of the vehicle, wherein the first absorbing structure is configured to, in case the vehicle is subject to a head-on collision with an object, act against the object and absorb all or most of a collision energy of the battery pack without transferring the battery pack collision energy to the vehicle body frame structure.

  • Patent number: 8161933
    Abstract: A starter arrangement for an internal combustion engine the arrangement including a starter motor having a pinion gear coupled to an output shaft, the pinion gear being arranged in constant engagement with a corresponding crank gear of a crank wheel located between an engine block and a flywheel of the engine. The crank wheel is operatively coupled to a crankshaft of the engine via a one-way clutch unit loosely fitted to an end of the crankshaft, the crankshaft including a circumferential slot carrying a clip ring. The one-way clutch unit including a tube shaped hub loosely fitted to an end of the crankshaft, the axial movement of the one-way hub is fixed via a clip-ring in co-operation with a first axially delimiting member and a second axially delimiting member at least partially enclosed by the hub.

  • Patent number: 7523819
    Abstract: An arrangement for controlling engagement and disengagement of two dry plate friction clutches (5,8) in a transmission having two concentric input shafts (3,6) comprising one release bearing (22,23) for each clutch on the transmission side of the clutches and one release bearing (36,37) for each clutch on the engine side of the clutches. The release bearing on the transmission side controls the operation of the release bearings on the engine side for disengagement of the clutches by means of intermediate push rods (28,29) extending through openings in a rotating element (7) connected to one of the clutches.

  • Patent number: 6691808
    Abstract: Drive unit for motor vehicles having an internal combustion engine (1), which, via a first clutch (3) can be coupled to a first input shaft (4) in a gearbox (5), and an electric machine (8), the rotor (10) of which is drivably coupled to a second input shaft (12), and can be coupled, via a second clutch (11) to the crankshaft (2) of the internal combustion engine. The second input shaft is a hollow shaft which can, via a transmission (27, 28, 29) with a third clutch (30), drive the crown wheel (26) in a differential (23) built together with the gearbox.

  • Patent number: 6457729
    Abstract: The invention provides a wheel suspension for a vehicle, wherein both a right wheel and a left wheel are carried by a linkage having a first end section and a second end section. The first end section is connected to the vehicle on the opposite side of the vehicle in relation to the respective wheel, and the second end section is likewise connected to its respective wheel. The invention is particulary significant in that the linkages are substantially U-shaped. Each linkage has two legs which are mainly parallel and extend in a substantially transverse direction of the vehicle. The free ends of the linkages constitute the first end section. The linkages also have a closed section connecting the legs. This closed section constitutes the second end section, whereby an open space is defined between the legs of each linkage. At least one leg on one of the linkages extends into the open space between the legs of the other linkage.
