The structure of the engine is specially used for extended range electric vehicles.

Description

The motor of extended-range electric vehicle and electric motor car thereof
Technical field
The utility model relates to a kind of automotive component and electric motor car thereof, particularly a kind of motor of extended-range electric vehicle and electric motor car thereof.
Background technique
The extended-range electric vehicle power system is made up of electrokinetic cell system, power-driven system, whole-control system and accessory power system (APU); Finish the operation control strategy by entire car controller.Battery pack can be by ground charging pile or onboard charger charging, and charge power supply drives generator by motor and produces, and motor can adopt fuel combustion type or gas-type.
In the prior art, the motor that extended-range electric vehicle uses all adopts existing motor car engine or uses logical machine motor, does not develop the special engine that is fit to extended-range electric vehicle.
Adopt available engine to have following shortcoming: available engine is high speed machine, peak output and Maximum Torque appear at about 6500-8500r/min, work operating mode and extended-range electric vehicle demand operating mode differ far away, need to use at extended-range electric vehicle through gear, cause inefficiency, the user cost height.The more high shortcoming of energy waste; And, former machine design all has devices such as driving mechanism, gear, starting mechanism, and the extended-range electric vehicle motor is not owing to belong to the vehicle traction structure, thereby all do not need said structure, and generally the method for Cai Yonging is in use former machine to be improved, but improve and all can not reach optimal effectiveness, make whole engine structure complexity, volume is bigger and heavier, causes cost of production and operating cost height, waste driving source, also cause the serious waste of resource; Be unfavorable for miniaturization, light-weighted vehicle design principle.
When particularly using logical machine motor, because its structural design is not suitable for vehicle mounted, when under the complex road condition condition, travelling, can cause each mechanism's insufficient lubrication of motor, problem such as the fuel oil supply is bad, and the noise that travels, vibrations are big, and comfort level is poor by bus.
Therefore, need improve the existing motor that increases the journey electric motor car, its work operating mode and extended-range electric vehicle demand operating mode are adapted, increase work efficiency, energy saving reduces and produces cost and operating cost, is applicable to that miniaturization, light-weighted vehicle use; Avoid in the prior art motor to the problem of the bad adaptability of the running environment of complex road condition, increase the travelling comfort of driving.
The model utility content
In view of this, the utility model provides a kind of motor and electric motor car thereof of extended-range electric vehicle, and its work operating mode and extended-range electric vehicle demand operating mode are adapted, increase work efficiency, energy saving reduces and produces cost and operating cost, is applicable to that miniaturization, light-weighted vehicle use; Avoid in the prior art motor to the problem of the bad adaptability of the running environment of complex road condition, increase the travelling comfort of driving.
The motor of extended-range electric vehicle of the present utility model, described motor are reciprocating engine, and the bent axle of motor is positioned at a crankcase, and described crankshaft two end extends crankcase and is used for the generator of direct-connected electric motor car at least; Adopt direct connection transmission structure, with respect to prior art, have transmission efficiency height, compact structure and alleviate the advantage of transmission system weight, cut down the consumption of energy, save and make and user cost; Crankshaft two end all stretches out crankcase, can drive more parts as far as possible, needs power-actuated parts such as being used for connecting air condition compressor, oil pump, water pump etc., has improved transmission efficiency, and the entrucking space is little, and is in light weight.
Further, the bent axle that reciprocating engine comprises cylinder assembly and is used for outputing power cooperates with the bent axle transmission to be provided with trunnion shaft; Adopt the trunnion shaft structure, simple in structure and very practical, can effectively slow down the car load vibration, improve the travelling comfort of driving.
Further, described motor is reciprocating engine, and the speed range of Maximum Torque and peak output is 3000-4000r/min; The rotating speed of maximum engine torque and peak output correspondence has determined the body structure of motor, and the engine weight of this structure, volume and operational efficiency are suitable for extended-range electric vehicle and use;
Also fixedly install on the described motor to be useful on and filter the empty filter enter engine air and for reducing the silencing apparatus of engine noise, described empty filter comprises empty filter assembly and steam outlet pipe, described steam outlet pipe is straight tube, and its internal diameter is 40-43mm, and length is 250-350mm; Empty filter does not indicate in the drawings, and certainly, empty filter also comprises suction tude, and empty filter assembly comprises sky filter housing, empty filter inner chamber and filter core, all belongs to prior art, does not repeat them here; Compare prior art, the internal diameter of the empty filter steam outlet pipe in the present embodiment and length all increase to some extent, thereby can promote the air inflow of engine inlets, promote the efficient of the whole gas handling system of motor, thereby reach the purpose that under same rotational speed, promotes engine power;
Described silencing apparatus comprises intake elbow, exhaust elbow and noise elimination assembly, and described intake elbow internal diameter is 21-24mm, and length is 350-450mm; Described exhaust elbow internal diameter is 29-31mm, and length is 250-350mm; Described noise elimination assembly comprises cylindrical shell, dividing plate I and dividing plate II, described dividing plate I and dividing plate II are divided into separate chamber I, chamber II and chamber III along airintake direction with described cylindrical shell, described noise elimination assembly also comprise for the pipe I that is communicated with intake elbow and chamber I, be used for communicated cavity I and chamber III the pipe II, be used for the pipe III of communicated cavity II and chamber III and be used for the pipe IV of communicated cavity II and exhaust elbow, the sealing of described pipe I outlet side, it places, and circumference is provided with the radial direction through hole that communicates for the chamber I on the interior pipeline section of chamber I; In the present embodiment, the internal diameter of silencing apparatus intake elbow and the bend pipe of giving vent to anger and length are compared prior art all to be increased to some extent, silencing apparatus is connected with the motor air outlet channel, for reducing engine noise, in the present embodiment, by the improvement to silencing apparatus, gas is circled round in separate chamber, can improve the noise elimination effect, but also can promote the air displacement of silencing apparatus simultaneously, namely improve the throughput of gas in silencing apparatus of engine emission, make engine exhaust smooth and easy, thereby reach the purpose that promotes engine output;
