Abstract

The invention belongs to the technical field of motor vehicles, and particularly relates to a vehicle transmission system and a vehicle. The vehicle transmission system comprises an engine, a variablepump and a controller, the variable pump is connected with a first transmission assembly through a second transmission assembly, and the variable pump is connected with two driving devices; a controller is respectively connected with the variable pump, the first driving device and the second driving device; and the first transmission assembly is connected with a fifth transmission assembly, the first driving device is connected with the fifth transmission assembly through a sixth transmission assembly, and the second driving device is connected with a fourth transmission assembly through a third transmission assembly. According to the scheme, the variable pump, the first driving device, the second driving device and the engine are used in a mixed mode, the first driving device is controlled to adjust output torque and the second driving device is controlled to adjust rotating speed through transmission of all transmission assemblies, coupling of the rotating speed and the torque is achieved, stepless speed change is achieved, and the engine can work in the area with the highest efficiency at different rotating speeds.

Description

technical field [0001] The invention belongs to the technical field of motor vehicles, and in particular relates to a transmission system of a vehicle and the vehicle. Background technique [0002] At present, traditional vehicles cannot make the engine work at the highest efficiency point at each operating point. Pure electric vehicles are limited by the battery cruising range, and the battery motors of gasoline-electric hybrid vehicles are more expensive and have lower power density. [0003] Whether the gearbox in the prior art is a multi-speed gearbox or other traditional power systems such as an AT gearbox, although the labor intensity of the driver is reduced, the engine cannot always work in the economical fuel consumption zone, resulting in high fuel consumption and cannot Realize energy recovery and generate energy waste. Contents of the invention [0004] The purpose of the present invention is at least to solve the problem that the existing transmission system ...
