  • Transmission
    Patent number: 10054196
    Abstract: A constant mesh gearbox has five parallel rotational axes. The input and output axes are not aligned. Up to eight forward speeds and two reverse speeds are disclosed, with two very low ratios suitable for non-highway travel. The transmission is suitable for two and four wheel drive.
    Type: Grant
    Filed: April 17, 2014
    Date of Patent: August 21, 2018
    Assignee: JAGUAR LAND ROVER LIMITED

  • Transmission
    Patent number: 9752655
    Abstract: A constant mesh gearbox has five parallel rotational axes. The input and output axes are not aligned. Some torque paths are via a sleeve rotatable on a shaft on one of said axes. Up to eight forward speeds are disclosed, with two very low ratios suitable for non-highway travel. The transmission is suitable for two and four wheel drive.

  • Transmission system
    Patent number: 9638315
    Abstract: A transmission system (8) comprising at least one floating gear (14a, 16a, 18a) rotationally mounted upon a first shaft the system comprising a floating gear activation system for controlling torque transfer between the at least one floating gear (14a, 16a, 18a) and the first shaft (10), the gear activation system comprising a first device (28, 30) having a friction interface (28) for frictional engagement with a friction interface (30) disposed on a first side of the at least one floating gear (18a), and a second device (25, 26) having a locking interface (25) for an interpositional engagement with a locking interface (26) disposed on a second side, opposing the first side, of the at least one floating gear (18a), whereby the floating gear (18a) is rotationally coupleable to the first shaft (10) by the friction interface (28/30) and/or the locking interface (25/26).
