Problems solved by technology

[0003] However, in the relevant technologies known to the inventor, some hybrid electric vehicles have few driving modes and low drive transmission efficiency, which cannot meet the requirements of the vehicle to adapt to various road conditions, especially after the hybrid electric vehicle is fed (when the battery power is insufficient). Insufficient vehicle power and passing capacity
Moreover, in order to realize the parking power generation condition, it is necessary to additionally increase the transmission mechanism, which has low integration and low power generation efficiency

Embodiment Construction

[0014] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0015] On a hybrid vehicle, the vehicle can be equipped with multiple systems, for example, a power transmission system 1000, which can be used to drive the front wheels or rear wheels of the vehicle. The following uses the power transmission system 1000 to drive the front wheels of the vehicle as an example To describe in detail, of course, the power transmission system 1000 can also be combined with other drive systems to drive the rear wheels of the vehicle to rotate, so that the vehicle is a four-wheel drive vehicle, and the other systems can be the electric drive system 700 .

[0016] A power transmission system 1000 according to an embodiment of the present...

Abstract

The invention discloses a power transmission system and a vehicle with the same. The power transmission system comprises a power source, a first motor generator unit, a system power output part, a first mode converting device and a second mode converting device. The first motor generator unit comprises a first motor generator and a unit coupling part which are connected, at least one of the powersource and the first motor generator unit is connected with or disconnected from the system power output part through the first mode converting device, the power source can be connected with or disconnected from the unit coupling part through the second mode converting device, the power source can be connected with the unit coupling part through the second mode converting device, and therefore power coming from the power source is subjected to speed reducing sequentially through the second mode converting device and the unit coupling part and then output to the first mode converting device. According to the power transmission system and the vehicle with the same, in this way, driving modes of the vehicle can be enriched, and the vehicle can adapt to different road conditions.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a power transmission system of a vehicle and a vehicle with the power transmission system. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy vehicles has gradually become a trend. As one of the new energy vehicles, a hybrid vehicle is driven by an engine and / or an electric motor, and has multiple modes, which can improve transmission efficiency and fuel economy. [0003] However, in the related technologies known to the inventor, some hybrid electric vehicles have few drive modes and low drive transmission efficiency, which cannot meet the requirements of the vehicle to adapt to various road conditions, especially after the hybrid electric vehicle is powered (when the battery power is insufficient). The power and passing capacity of the whole vehicle are insufficient. Moreover, in order to realize the...
