  • Gearbox synchromesh, with a splined flange for the translational movement of the hub
    Patent number: 9829051
    Abstract: A gearbox (BV) comprises a secondary shaft (AS) provided with a synchromesh (SB) comprising a flange (FL) comprising a sub-hub (SM) fixedly secured to the secondary shaft (AS) and provided with external splines (CE3), a hub (MO) comprising internal splines (CI1) collaborating with the external splines (CE3) of the sub-hub (SM) to allow translational movement with respect to the latter (SM), and a sleeve (MA) that can undergo a translational movement with respect to the hub (MO) so that the internal splines (CI2) thereof are closely coupled to dogs (CR) of an idling pinion (PF1). This translational movement of the hub (MO) with respect to the sub-hub (SM) guarantees close coupling of the internal splines (CI2) of the sleeve (MA) with the dogs (CR) with a minimal margin for translation, irrespective of dimensional variations in the manufacture of the sleeve (MA) and idling pinion (PF1).

  • Device for transmitting power between the output of a thermal engine and a wheel shaft, and use of said device
    Patent number: 8287413
    Abstract: The invention relates to a power transmission device (1.1) that comprises an input shaft (2) to be connected to a thermal engine (3) and an output shaft (4) to be connected to a wheel shaft (5). The device (1.1) includes first and second electric machines (6, 7) and a mechanical assembly (12) ensuring the mechanical link between the input shaft, the output shaft and the shafts (8, 9) of the machines (6, 7). According to the invention, in order to limit the use of the epicyclic gear trains, at least one of the electric machines (8, 9) comprises a rotor (6.1) and a stator (6.2) connected to the mechanical assembly (12).
