Abstract
The utility model relates to a miniature electric car, belonging to a vehicle which is driven by a DC motor. The utility model adopts accumulators as a power supply, and is driven by the DC motor; the utility model is additionally provided with a semi-sphere and friction wheel stepless speed change mechanism and a spiral track steering mechanism which are used to achieve the speed change, reverse running and steering of the utility model. The utility model has the advantages of small volume, light weight, high flexibility, simple structure, low manufacture cost, no exhaust pollution, etc.
Description
The utility model relates to a kind of vehicle that advances with DC motor.
At present, the useful storage battery of vehicle that advances with DC motor is as the storage battery car of power supply.It is used for factory floor, station platform level land short-haul operation goods more.This class storage battery storage battery car is not seen as yet and is used for the small passenger car aspect, moreover mostly its steering hardware is to adopt Worm-gear type mechanism.Complex structure, cost is higher.
The purpose of this utility model provides a kind of miniature electric car, uses for the vast city people.
Technical solution of the present utility model is: adopt storage battery power supply, DC motor drives; Hemisphere face and friction wheel stepless variable speed machine by friction structure, spiral orbit formula steering hardware realize this baby car speed change, move backward and turn to.Below in conjunction with accompanying drawing the utility model is described in detail.This miniature electric car comprises existing wheel, vehicle frame, reaches bicycle shed etc., and it is powered to DC motor (8) by storage battery (12), and the output shaft design of motor has friction hemisphere (7), drives friction wheel (6) by its and rotates.A fritter is removed at top of its friction hemisphere, makes it become the plane, and when the wheel rim of friction wheel during over against this plane, no touch between them forms " neutral gear " position.Friction wheel (6) adopts key pin to be connected with rotating shaft (13), the other end design of rotating shaft has sprocket wheel, chain device (10), directly driving a rear wheel by it rotates---single wheel drive, design one damping spring (11) between trailing wheel and vehicle frame, to play buffer action, another rear wheel and two front-wheels belong to flower wheel.Rotating shaft (13) is bearing on two shaft supports (5).The steering hardware of this car (1) adopts spiral orbit formula structure (see figure 3), it comprises spiral orbit (15), track plate (16), tierod (14) and direction lever (17), track plate (16) and direction lever (17) are for being rigidly connected, track (15) is scroll, it and track plate (16) integrally welded (perhaps inblock cast shapes).Pane is protruded in the one end weldering one of intermediate rod (14), open a breach in the middle of the projection, the breach face is designed to circular arc and is embedded in wherein slip freely in order to spiral orbit (15), when direction lever drives the track plate rotation, spiral orbit (15) drives lateral connecting rod (14) side-to-side movement, and swinging with the control front-wheel turns to; The speed change of this car adopts hemisphere face and friction wheel stepless variable speed machine by friction structure.Transmission principle as shown in Figure 4, friction hemisphere (7) and friction wheel (6) are formed the main body of speed-changing mechanism, hemisphere (7) is that 180 degree are rotated at the center with the centre of sphere in horizontal surface with motor (8), when the midway location that is in Fig. 4, be " neutral gear " that hemisphere upwards rotates, the friction wheel rim begins to contact sphere, slow start when the friction wheel rim touches the maximum disc place of hemisphere, reaches the most at a high speed; When hemisphere rotates, form " reverse ".Motor is installed on the electric machine support (9), and it realizes its rotation by the control of the cover connecting rod hinge device that electric machine support axle (20), support pivoted arm (21), connection rod of gear shifting (3) and gear change hand lever (2) are formed.Electric machine support axle (20) is gone up design one electric machine support axle supporting (19), and its right-hand member is adorned an energizing spring (18), to guarantee wipe contact pressure.The brake equipment of this miniature electric car is similar to existing vehicle with illumination equipment etc., does not describe in detail in addition.
This miniature electric car is owing to designed hemisphere face and friction wheel stepless speed changing mechanism, spiral orbit formula steering hardware, storage battery power supply, DC machine drives, then to have a volume little for this car, characteristics such as light and flexible, simple in structure, low cost of manufacture, and do not have exhaust pollution, be fit to the city and use.
