Abstract

The invention relates to a motive power mixing device of a hybrid car. A first single direction clutch is arranged between an output spline shaft of an internal combustion engine and a driven wheel, and a second single direction clutch is arranged between the motor and the driven wheel. Due to the fact that only two sets of new single direction clutches are arranged except for the commonly used vehicle internal combustion engine and the motor, the advantages of a small-displacement fuel engine of high efficiency, oil saving, reasonable structure, mature technology and low cost are sufficiently utilized, the advantages of a direct current motor of large starting torsion and high efficiency and effort saving are sufficiently utilizedto achieve motive power optimization combination, and the motive power mixing device of the hybrid car dose not waste power, and is convenient to operate and capable of achieving motive power optimization combination.

Description

A kind of power mixing device of hybrid electric vehicle

Technical field

The invention belongs to hybrid electric vehicle production and transformation field, relate in particular to a kind of power mixing device of hybrid electric vehicle.

Background technology

Common hybrid-power electric vehicle, following situations often appears in the combination of electric two systems of its oil: namely 1, the driving power that has several times changes, energy dissipation is serious, start to be with the electrical generator generating with spark ignition engine, with the electricity that sends, battery is charged again, then with the work of battery driving electric machine, several times conversion, inefficiency causes the waste of fuel and the consumption of kinetic energy to increase; Some drivings directly are connected, and check and balance, and have plenty of power and are not connected onboard, but whole drive system is connected, and drive respectively as front-rear axle, and rotating speed is inharmonious, all exists kinetic energy to keep waste in check.2, electrical generator repeats to arrange, and causes equipment waste, kinetic energy consumption to increase, and concrete manifestation A often sets up again an electrical generator in the situation that former explosive motor has been accompanied with electrical generator, and uses seldom separately; B is that generator charging that former explosive motor is set up only fills single only 12 volts of electricity, can't be to batteries charging, but dally when explosive motor is worked always; 3, complex structure, car body is huge, and cost is high, and efficient is low, as domestic and international most hybrid electric vehicles.

Summary of the invention

the objective of the invention is by outside general automobile-used explosive motor and electrical motor (comprising itself operating system), take full advantage of novel free-wheel clutch power single-direction transmission, can interrupt the characteristics of power transmission and superposition power, (or utilize original reverse gear with neutral gear by adding 2 cover free-wheel clutchs, shifting device) and additional setting commonly used, take full advantage of existing high efficiency, oil saving oil-burning machine (as domestic air-cooled 110, 150, water-cooled 150, 200, 376, 0.9 liter of TwinAir driving engine of Fiat, 1.0 liters of EcoBoost driving engines of Ford, 1.0 liters of VVT-i driving engines of Toyota), rational in infrastructure, technology maturation, advantage with low cost, utilize series machine to start torsion large, brushless DC hub-motor is efficiently economized the advantage of merit, realize that power improves combination, do not waste power, handled easily, especially with the hybrid power transformation of this system to existing fuel combustion vehicle, part is economized, change little, complete fast, cost is low, by the additional charging converter of the electrical generator of former explosive motor (boost charge controller or single battery charging switch controller), can carry out desirable charging to whole battery pack, without the waste of any power capacity and facility.

The invention provides a kind of power mixing device of hybrid electric vehicle, the explosive motor output spline and and flower wheel between be provided with the first free-wheel clutch, be provided with the second free-wheel clutch between described flower wheel and electrical motor.

Preferably, described free-wheel clutch is the neutral gear and D Drive and reverse gear composition of flywheel, unilateral bearing, click, overriding clutch or change-speed box.

Select described flower wheel and can be provided with reverse gear between diff thereafter excellently.

Preferably, described driving engine output spline is connected with the first universal-joint spline housing, described the first universal-joint spline housing also is connected with universal-joint, described universal-joint also with the second universal-joint spline housing, described the first overriding clutch is arranged between described the second universal-joint spline housing and described flower wheel.

Preferably, described diff is connected with described diff by the second driving engine output spline and the 3rd universal-joint spline housing.

Preferably, the electrical generator set up of explosive motor is connected with charging converter.

Preferably, charging converter comprises boost charge controller or single battery charging switch controller.

The present invention is by only establishing the two novel free-wheel clutchs of cover or neutral gear reverse gear, shifting device and simple additional the setting being arranged outside general automobile-used explosive motor and electrical motor, take full advantage of the high efficiency, oil saving of existing small displacement oil-burning machine, rational in infrastructure, technology maturation, advantage with low cost, take full advantage of series machine and start that torsion is large and brushless DC hub-motor is efficient, the advantage of province's merit, realize that power improves combination, do not waste power, handled easily can realize that power improves combination; By the additional charging converter of the electrical generator of former explosive motor, can carry out desirable charging to whole battery pack, the also i.e. realization of generating, charge function, without the waste of any power capacity and the waste of facility, carry out the production of economic type electric car with the method especially and the hybrid power of existing fuel combustion vehicle is transformed, adding part few, changing little, complete soon, cost is low.
