Abstract
The utility model relates to a range increasing generator structure integrated with a cylinder. The range increasing generator structure is formed by a motor casing, an engine cylinder and a motor rotor and is characterized in that the motor casing is located at one side of the engine cylinder, the motor casing and the engine cylinder are integrated to be a whole structure, the motor rotor is in the motor casing, and a cooling water jacket in the engine cylinder is communicated with a cooling water jacket in the motor casing. The engine cylinder and the motor casing are arranged in an integrated way, thus a power assembly has a compact structure, the change cost is effectively reduced, the impact on a traditional engine is small, the whole vehicle efficiency can be greatly improved, an engine is communicated with a motor cooling system, the circulation resistance is small, and the cooling effect is good.
Description
Technical field
The utility model relates to extended-range electric generator structure a kind of and that cylinder body is integrated, belongs to the technical field of range-extended electric car generator research and development, particularly the integrated design assembly of a kind of engine cylinder-body and generator.
Background technology
Extended-range (English Range Extender, being called for short RE) pure electric automobile is a kind of novel new-energy automobile product of automobile industry primary study and development both at home and abroad in recent years, as a kind of pure electric automobile that increases continual mileage, the RE pure electric automobile has the technological merit of hybrid vehicle and pure electric automobile concurrently: (1) pure electronic continual mileage satisfies quite most of personnel distance travelled every day requirement greater than the RE electric motor car of 60km; (2) use of distance increasing unit has increased the car load continual mileage, avoids the driver to the worry of distance travelled; (3) compare with pure electric vehicle, system cost reduces, and reduces the unify cost of energy storage system of vehicle transmission system; (4) simultaneously can reduce battery reliability and life-span deficiency again, be subjected to adverse effect such as condition of work (temperature) restriction; (5) increased useful life of electrokinetic cell; (6) can increase the user to the acceptance of pure electric automobile; (7) when the discharge power of electrokinetic cell is restricted, distance increasing unit can supplemental capacity the part of deficiency, guarantee that car load has good power performance, or by distance increasing unit provide power with cooling or pre-thermal cell to guarantee the normal serviceability of electrokinetic cell.
At present, many and the engine tandem layout of extended-range motor, need increase whole power assembly axial length this moment, requirements of installation space is big, and this moment, motor was also very big to the cantilever action of bent axle, supports behind the bent axle of conventional engines to be difficult to meet the demands, and the transducer of motor, three line terminals interfaces all are difficult to arrange, especially the cooling recirculation system of motor needs design separately, if prolong the cool cycles water route of engine, then needs to increase system factors such as water pump ability.
Summary of the invention
The purpose of this utility model provides extended-range electric generator structure a kind of and that cylinder body is integrated, the integrated layout of engine cylinder-body and electric machine casing, make the power assembly compact conformation, effectively reduced variable cost, also little to the conventional engines influence, car load efficient can be greatly improved, and engine communicates with the motor cooling system, circulation resistance is little, good cooling results.
The technical solution of the utility model is achieved in that the extended-range electric generator structure that a kind of and cylinder body is integrated, formed by electric machine casing, engine cylinder-body, rotor, it is characterized in that: electric machine casing is positioned at engine cylinder-body one side, electric machine casing and the engine cylinder-body formula structure that becomes one, rotor is arranged in electric machine casing, and the cooling jacket of engine cylinder-body inside communicates with cooling jacket in the electric machine casing.
Good effect of the present utility model is the integrated layout of engine cylinder-body and electric machine casing, make to have effectively reduced variable cost by the power assembly compact conformation, also little to the conventional engines influence, car load efficient can be greatly improved, and engine communicates with the motor cooling system, reduces pipeline and connects, and reduces circulation resistance, good cooling results, can effectively reduce generating assembly axial length, conserve space is convenient to layout, the application of car load.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
That the utility model is described in further detail is bright below in conjunction with accompanying drawing: as shown in Figure 1, the extended-range electric generator structure that a kind of and cylinder body is integrated, by electric machine casing 1, engine cylinder-body 2, rotor 3 is formed, it is characterized in that: electric machine casing 1 is positioned at engine cylinder-body 2 one sides, electric machine casing 1 and the engine cylinder-body 2 formula structure that becomes one, rotor 3 is arranged in electric machine casing 1, rotor 3 can obtain power from engine crankshaft by gear train or chain system, generation rotatablely moves, make motor finish electricity generate function, the cooling jacket of engine cylinder-body 2 inside communicates with cooling jacket in the electric machine casing 1, and can improve cooling effectiveness.This kind structure can make electric machine casing 1 not need extra installing and fixing a little, and can effectively reduce the axial length of whole assembly.
When distance increasing unit moves, engine is by gear or chain drive generator for electricity generation, can control engine and work in optimum fuel-economy district this moment, greatly improved engine power generation efficient, the economy of car load is greatly improved, and the cooling system of engine cylinder-body 2 communicates with the cooling system of electric machine casing 1, can share cooling water channel, reduce connecting line, reduce the cooling system circulation resistance, strengthen cooling effect.
