Abstract

The invention relates to a power distribution hydraulic hybrid power drive device and a vehicle. The power distribution hydraulic hybrid power drive device comprises a first drive unit and a second drive unit connected in parallel, and a central controller connected with the first drive unit and the second drive unit, wherein the first drive unit comprises an engine, a first clutch, a force takeoff device connected with the engine, a gearbox connected with the power takeoff device through the first clutch and a drive axle connected with the gearbox; the second drive unit comprises a hydraulic variable pump, a hydraulic energy storage device, a hydraulic pump motor and a torque coupler; the hydraulic variable pump is connected with the power takeoff device; and the torque coupler is also connected with the gearbox and the drive axle of the first drive unit. According to the power distribution hydraulic hybrid power drive device, hydrostatic transmission and / or mechanical transmission can be reasonably adopted by the central controller according to the running condition of the vehicle, so that the transmission efficiency of the whole vehicle is improved and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a driving device and a corresponding vehicle, in particular to a power split hydraulic hybrid driving device and a vehicle. Background technique [0002] At present, the problem of energy shortage and environmental pollution is becoming more and more serious, and it is urgent to save energy and reduce emissions in various fields. There are a large number of vehicles, high energy consumption, and frequent start and stop operations, which are also the first choice for energy saving and emission reduction. At the same time, the annual snowfall period in the alpine regions of northern my country is as long as 5 to 6 months, and the snow on the roads has brought a lot of inconvenience to transportation. [0003] During the use of special snow removal vehicles, it is necessary to melt the ice and snow on the road surface by spreading deicing agent or salt water. However, due to the influence of the external environment, its snow re...
