Description

TEKNISKT OMRADE FOreliggande uppf inning avser en bil omfattande fOrbrgnningsmotor och elmotor samt separat manOverpanel fOr eldriften. Forbranningsmotorn gr avsedd for drift av bilen pa lgngre strackor, och elmotorn for drift pa kortare strackor. TECHNICAL FIELD The present invention relates to a car comprising an internal combustion engine and an electric motor as well as a separate control panel for electric propulsion. The internal combustion engine is intended for operation of the car on longer distances, and the electric motor for operation on shorter distances.

TEKNIKENS STANDPUNKT Det ar tidigare kant att for driften av bil utnyttja savgl fOrbranningsmotor som elmotor. Sa-Ar det kgnt t.ex. genom svenska utlaggningsskriften 428 782 en framdrivningsanordning fOr fordon innefattande en forsta maskin anordnad som framdrivningsmotor och att dgrvid drivas genom forbrgnning av ett drivmedel och en andra maskin anordnad som alternativ framdrivningsmotor och dgrvid drivas med elektrisk strOm fran batten. Batteriet ar anordnat att uppladdas med strom genererad medelst den forsta maskinens arbete. STATE OF THE ART It is previously possible to use a saw combustion engine as an electric motor for the operation of a car. Sa-Ar det kgnt e.g. by Swedish Laid-Open Specification 428 782 a propulsion device for vehicles comprising a first machine arranged as a propulsion motor and thereby driven by the consumption of a fuel and a second machine arranged as an alternative propulsion motor and thereby driven by electric current from the boat. The battery is arranged to be charged with power generated by the operation of the first machine.

Vidare Er det genom europeiska patentet 0046997 kEnt en elektrisk hjuldrivning for motorfordon med fOrbranningsmotor med till hjulen sasom hjulnavmotorer tillordnade och fran ett lgmpligt anordnat batten i matade separata elektromotorer, varvid hjulnavmotorerna är delar av ett drivsystem som finns oberoende bredvid en konventionell fOrbranningsmotordrivanordning. Furthermore, European patent 0046997 discloses an electric wheel drive for motor vehicles with internal combustion engines with to the wheels as wheel hub motors attached and from a suitably arranged bat in fed separate electric motors, the wheel hub motors being parts of a drive system which is independently adjacent to a conventional drive motor.

Vid studium av pAgAende elbilsprojekt har framkommit att kostnaderna är for hOga i fOrhallande till den komfort och det anvandningsomrade tom uppnatts. Vidare kan framtagen elbil ej utnyttjas vid langre kOrstrackor; installerade batterier inkrgktar pa bilens utrymme och utgOr viktmassigt en stor belastning. 212 2 REDOGORELSE FOR UPPFINNINGEN En enligt uppfinningen utformad bil av det i det fbregAende omndmnt slag har elmotorn med tillhorande batterier anordnade pA en separat, med hjulpar forsedd och till bilens fyrhjuliga chassi mekaniskt och elektriskt hopkopplingsbar vagn, vars hjulpar Ar anordnat att drivas medelst elmotorn och styras genom impulser initierade frAn bilens konventionella styrsystem. When studying pagan electric car projects, it has emerged that the costs are too high in relation to the comfort and the area of use even reached. Furthermore, the developed electric car can not be used for longer driving distances; installed batteries encroach on the car's space and constitute a large load in terms of weight. DISCLOSURE OF THE INVENTION A car designed according to the invention of the type mentioned above has the electric motor with associated batteries arranged on a separate, wheeled chassis and mechanically and electrically interconnectable car to the car's four-wheel chassis, the pair of wheels Ar arranged to be driven by electric motor is controlled by impulses initiated from the car's conventional control system.

FIGURBESKRIVNING Uppfinningen skall ndrmare beskrivas i anslutning till bifogade ritning, som schematiskt visar en bil med mekaniskt och elektriskt tillkopplad tvAhjulig vagn med batterier och elmotor. DESCRIPTION OF THE FIGURES The invention will be described in more detail in connection with the accompanying drawing, which schematically shows a car with a mechanically and electrically connected two-wheeled carriage with batteries and an electric motor.

FOREDRAGEN UTFORINGSFORM PA ritningen visas schematiskt en ordingr fyrhjuiig bil 10 och en till bilens bakre'dnde kopplad tvAhjuli vagn 11. PREFERRED EMBODIMENT The drawing schematically shows a four-wheel drive car 10 and a two-wheeled carriage 11 connected to the rear of the car.

Mien 10 är en konventionell standardbil kompletterad med organ for mojliggOrande av. drift av bilen genom batterier-elmotor anordnade pA vagnen 11. I det foljande kommer endast organen och funktioner for eldriften att ndrmare anges och kommenteras; for drift av bilen genom fOrbranningsmotorn erforderliga detaljer och funktioner är allmdnt valkanda och kommer ddrfOr ej att ngrmare bertiras. The Mien 10 is a conventional standard car supplemented with means for enabling. operation of the car by batteries-electric motor arranged on the carriage 11. In the following, only the means and functions of the electric drive will be further specified and commented on; The details and functions required for the operation of the car through the internal combustion engine are generally optional and will therefore not be discussed further.

Bilen 10 har i anslutning till fbrarsatet en instrumentpanel 101, manoverorgan 102 och en pedal 103. En anslutningskabel 104 leder fran instrumentpanelen 101 till anslutningsdon 105 langst bak i bilen for anslutning till vagnen 11. The car 10 has in connection with the vehicle an instrument panel 101, actuator 102 and a pedal 103. A connecting cable 104 leads from the instrument panel 101 to the connector 105 at the rear of the car for connection to the carriage 11.

Vagnen 11 at mekaniskt kopplad till bilen 10 Over tvA kulkopplingar 12. Vagnen har tvA elmotorer 111, batterier 112, batteriladdare 113, elektronikenhet 114 samt styrkolv 115. The trolley 11 is mechanically connected to the car 10 Over two ball couplings 12. The trolley has two electric motors 111, batteries 112, battery chargers 113, electronics unit 114 and steering piston 115.

Huvud principen är alltsA att vagnen 11, som är mekaniskt/elektriskt kopplad till bilen 10, utgor drivenheten vid eldrift med elmotorerna 111 och batterierna 112. Vagnens hjul är elektriskt 3 eller hydrauliskt styrbara via styrkolven 115 i beroende av rarens rattrdrelser i bilen. The main principle is that the carriage 11, which is mechanically / electrically connected to the car 10, forms the drive unit for electric operation with the electric motors 111 and the batteries 112. The carriage wheels are electrically or hydraulically steerable via the steering piston 115 depending on the rudder movements of the car.

De separatmagnetiserade elmotorerna 111 av likstromstyp fungerar som generatorer vid motorbromsning och omvandlar alltsA bilens rbrelseenergi till elstrbm som ledes till batterierna 112. Batterierna 112 i kassettter ar placerade sA att de latt kan bytas vid laddningsstationer. FOr kortare kOrstrackor kan antalet batterier latt minskas varigenom dessa kOrningar kan genomfbras med minsta mbjliga vikt i vagnen. The separate magnetized electric motors 111 of the direct current type act as generators during engine braking and thus convert the car's kinetic energy into electric current which is led to the batteries 112. The batteries 112 in cassettes are placed so that they can be easily replaced at charging stations. For shorter driving distances, the number of batteries can be easily reduced, as a result of which these runs can be carried out with the least possible weight in the trolley.

Vid langre kOrstrackor kopplas vagnen ifrAn och bilen drivs pA vanligt satt med fOrbranningsmotorn. For longer driving distances, the trolley is switched off and the car is driven in the usual way with the internal combustion engine.

Vagnen 11 är vidare fOrsedd med hydrauliskt bromssystem som Over anslutningsdonet 105 är hopkopplat med bilens bromssystem. The trolley 11 is further provided with a hydraulic braking system which the Over connector 105 is connected to the car's braking system.

Den pA ritningen visade bilen for eldrift har en vagn tillkopplad medelst tvA kulkopplingar. Man kan tanka sig aven en enda kulkoppling som dA naturligtvis ar centralt placerad. Vidare antyds pA ritningen tvA elmotorer. Det gAr ocksA att ordna med en enda elmotor och modifierad mekanisk kraftbverfbring till hjulen. The car shown in the drawing for electric operation has a trolley connected by means of two ball couplings. You can also think of a single ball coupling which is of course centrally located. Furthermore, the drawing indicates two electric motors. It is also possible to arrange a single electric motor and modified mechanical power transmission to the wheels.
