摘要 | A transmission system for a vehicle has a first transmission module with at least one speed transforming gear and at least one coupling. The system may further include a second transmission module with at least one speed transforming gear and at least one coupling, wherein an input shaft of the first transmission module is connected to a drive source and an output shaft of the second transmission module iss connected to an end drive. An electromotor may be coupled to the first transmission module and/or the second transmission module, via a mount point. The first transmission module and the second transmission module may be arranged in series with an output shaft of the first transmission module being connected to an input shaft of the second transmission module. | ||||||

说明书全文 | This application for a utility patent is a divisional of a previously filed utility patent Ser. No. 13/590,562, filed Aug. 21, 2012, which is a continuation of a previously filed utility patent, now abandoned, having the application number PCT/NL2011/050135, filed Feb. 24, 2011 (Publication No.: WO2011/105905). 1. Field of the Invention The invention relates to a transmission system for a vehicle comprising a first and a second transmission module which each comprise at least one speed transforming gear and at least one coupling and/or a continuously variable transmission with a controllable variable speed transforming gear, where an input shaft of the first transmission module can be coupled to an end drive which is connected to wheels of the vehicle, which transmission system further includes an electromotor which is coupled to one or both transmission modules. 2. Description of Related Art A transmission system of this general type is known; however, in the known transmission system, the transmission modules are arranged in parallel with each other between the input and the output of the transmission system. The present invention relates to a transmission system having a first transmission module with at least one speed transforming gear and at least one coupling, and/or a continuously variable transmission with a controllable variable speed transforming gear. A second transmission module may also be included with at least one speed transforming gear and at least one coupling, wherein an input shaft of the first transmission module is connected to a drive source and an output shaft of the second transmission module iss connected to an end drive. An electromotor may be coupled to the first transmission module and/or the second transmission module, via a mount point, wherein the first transmission module and the second transmission module are arranged in series with an output shaft of the first transmission module being connected to an input shaft of the second transmission module. The invention will be described below in more detail based on examples of embodiment of the transmission system according to the invention represented in the drawing figures, in which: An input shaft 6 of the first transmission module 1 can be coupled to a drive source 3. An output shaft 12 of the second transmission module 2 may be coupled to an end drive 4a which may then be connected to wheels (not shown) of the vehicle and/or to a differential 4b. The electromotor 7 may be coupled to the first transmission module 1 or to the second transmission module 2. Also, the first transmission module 1 and the second transmission module 2 may be arranged in series with the output shaft 8 of the first transmission module 1 being connected to the input shaft 10 of the second transmission module 2. The electromotor 7 may be connected, via a mount point 5, to the output shaft 8 of the first transmission module 1 and/or the input shaft 10 of the second transmission module 2. The first transmission module 1 and/or the second transmission module 2 may have two (or more) switchable controllable speed transforming gears by means of which various forward gears can be realized. |
