Embodiment Construction
[0034] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0035] The invention discloses a driving system of a hybrid four-speed transmission. Synchronizers are respectively integrated on both sides of the second gear 5 and the fifth gear 9, and the device is idly fitted on the two output shafts of the transmission. Only one input gear 7 is needed to realize the four-speed drive of the engine, which not only makes the structure of the gearbox more compact, but also simplifies the structure of the transmission system. The simplest transmission system can be used to realize the four-speed drive of the engine, thereby achieving Achieve the effect of using simple transmission system structure to realize complex functions.
[0036] In addition, sinc...

The invention discloses a driving system of a hybrid four-speed transmission. Synchronizers are respectively integrated on both sides of the second gear and the fifth gear, and the device is vacantly placed on the two output shafts of the gearbox. One input gear can realize the four-speed drive of the engine, which not only makes the structure of the gearbox more compact, but also simplifies the structure of the transmission system. The four-speed drive of the engine can be realized by using the simplest transmission system, thus achieving simple use. The advanced transmission system structure realizes the effect of complex functions. And because the gear and the synchronizer are both empty sleeves on the shaft, during the operation of the entire transmission system, the two input shafts will not follow the rotation, thereby reducing energy loss and improving energy transmission efficiency.
Description
technical field [0001] The present application relates to the technical field of vehicles, in particular to a hybrid four-speed transmission driving system. Background technique [0002] With the continuous development of vehicle technology, the characteristics of vehicles such as fuel economy, low emission, fuel saving rate and power performance are increasingly concerned. [0003] These characteristics depend largely on the strengths and weaknesses of the vehicle's hybrid four-speed transmission drive system. [0004] In the prior art, in order to realize the four-speed driving of the engine, hybrid vehicles usually need to be provided with two input gears on the input shaft of the gearbox, and two output gears on the two output shafts, two sets of intermediate transmission gears and The output shaft is fixedly connected to the synchronizer. Moreover, when the driving motor is driven, corresponding gears need to be provided separately, which results in a large number of ...
