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

[0015] 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.

[0016] On a hybrid vehicle, the vehicle can be equipped with multiple driving systems, for example, a power transmission system 1000, which can be used to drive the front wheels or rear wheels of the vehicle, and the following uses the power transmission system 1000 to drive the front wheels of the vehicle as Example for detailed description, of course, in some optional embodiments, the vehicle 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, for example, the vehicle can also be combined with the electric drive system 700 to drive the vehicle's The rear wheels turn....

Abstract

The invention discloses a power transmission system for a vehicle and a vehicle with same. The power transmission system for the vehicle comprises a power source, a first electric power generator unit, a system power output part and a mode conversion device; the mode conversion device comprises a main reducer driven gear and a planet gear mechanism; the main reducer driven gear is suitable for outputting power from at least one of the power source and the first electric power generator unit; the planet gear mechanism comprises a sun gear, a planet carrier and a gear ring; the sun gear is fixedly connected with the main reducer driven gear; the planet carrier is connected with an input end of the system power output part; the gear ring can be selectively braked; and the gear ring is brakedso that the rotation speed of the main reducer driven gear is higher than that of the input end of the system power output part. The power transmission system for the vehicle has the advantages of large gear number and more working modes.

Description

technical field [0001] The invention belongs to the technical field of transmission, and in particular relates 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 rea...
