Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. As shown in Figure 1, an engine-hydraulic parallel rear-drive hybrid vehicle is powered alternately or simultaneously by the main power system of the engine and the auxiliary power system of hydraulic energy after energy recovery, and adopts the drive mode of the rear drive axle. Recovery is to collect and store the recyclable energy of engine peak shaving energy, braking energy and idling in the hydraulic accumulator, and then release the hydraulic energy at any time during engine start, power vehicle start and driving to achieve hybrid The purpose of power drive.

[0018] Basic structure of the present invention

[0019] The basic structure of the present invention comprises brake pedal 2, accelerator pedal 3, left rear wheel 12 and right rear wheel 13, also comprises main power mechanism, main auxiliary power mechani...

Abstract

The present invention relates to an engine-hydraulic series-parallel connection type rear drive hybrid vehicle. It is composed of main power mechanism, main auxiliary power mechanism, secondary auxiliary power mechanism and double-power rear drive axle. Said main power mechanism is formed from engine and gear-box, its main auxiliary power mechanism is composed of hydraulic control valve group, hydraulic energy storage, hydraulic pump / motor and hydraulic fuel tank, its secondary auxiliary power mechanism is formed from engine power output mechanism, secondary electromagnetic clutch, hydraulic pump, secondary hydraulic fuel tank and secondary hydraulic control valve group. Besides, said invention also provides their connection mode and working principle of said engine-hydraulic series-parallel connection type rear drive hybrid vehicle.

Description

technical field [0001] The invention relates to a clean and energy-saving hybrid rear-drive hybrid vehicle equipped with an engine and a hydraulic accumulator. The invention relates to a technology for realizing a hybrid rear-drive hybrid vehicle, especially a kind of engine-based power source , and to store and release the hydraulic energy as the auxiliary power source of the serial rear-drive hybrid electric vehicle, the present invention relates to the ability to improve the energy storage of the hydraulic hybrid electric vehicle, the present invention relates to the engine power excess peak-shaving performance, and will be due to The excess energy generated when the vehicle is idling is recovered and the service life of the engine is extended. Background technique [0002] With the sharp increase of the number of power vehicles in our country, a power vehicle with high efficiency, good performance and simple structure will be welcomed by the society. Since the power veh...
