Embodiment
Fig. 1 ~ 2 are most preferred embodiments of the present utility model, are described further below in conjunction with accompanying drawing 1 ~ 2 pair of the utility model.
As shown in Figure 1, caravan DC driven reducing motor, comprises motor 1, reduction box 2 and cylinder 4.Motor 1 is vertically set on the middle part of reduction box 2, and reduction box 2 is horizontally installed on the front end of motor 1, and motor 1 is fixing more firm, reaches the effect extending direct current machine useful life, reduce noise.The power shaft of output shaft from the middle part of reduction box 2 with reduction box 2 of motor 1 is connected, the power that reduction box 2 provides cylinder 4 to rotate.Be respectively arranged with headstock and bracing frame 3 in the left and right sides of reduction box 2, cylinder 4 is rotating to be fixed between headstock and bracing frame 3, is fixed with case lid 5 in the outside of headstock.Achieve motor 1, reduction box 2 and cylinder 4 to arrange successively along the axis of motor 1, and the axes normal of cylinder 4 is in the axis of motor 1, therefore makes the driving force performance of cylinder 4 more superior.
Propulsion plant 9 is also provided with immediately below motor 1, motor 1, reduction box 2 and cylinder 4 entirety can be promoted by propulsion plant 9 advance or retreat, when propulsion plant 9 promote motor 1, reduction box 2 and cylinder 4 advance time, cylinder 4 contacts with automobile tire, there is provided required power by cylinder 4, realize caravan movement interior among a small circle by tire on the drive wheels.When propulsion plant 9 driving electric machine 1, reduction box 2 and cylinder 4 entirety retreats, cylinder 4 and automobile tire depart from, and propulsion plant 9 realizes by linear electric motors.
As shown in Figure 1 and 2, the 3rd gear 6, first gear 7, second gear 8 and gear shaft 10 is provided with in the headstock of reduction box 2.The two ends of gear shaft 10 are separately fixed at reduction box 2 with on case lid 5 by bearing, and the inside and outside both sides of gear shaft 10 are respectively arranged with worm gear 12 and the first gear 7.The axle head of motor 1 output shaft is through bearing connecting worm 11, worm screw 11 engages with the worm gear 12 be arranged on inside gear shaft 10, the first gear 7 be arranged on outside gear shaft 10 is meshed with the second gear 8, and the number of teeth of the first gear 7 is less than the number of teeth of the second gear 8.Second gear 8 is fixed on axis therein by bearing, and the axis of the second gear 8 is fixed in reduction box 2 headstock by the bearing of its both sides.Second gear 8 is meshed with the 3rd gear 6, and the number of teeth of the 3rd gear 6 is more than the number of teeth of the second gear 8.
3rd gear 6 connects the output shaft in it by key, the both sides of the 3rd gear 6 output shaft are fixed in reduction box 2 headstock respectively by bearing, the inner of 3rd gear 6 output shaft is designed for hexahedron, hexahedron is inwardly through loading in cylinder 4 after the medial surface of headstock, moment of torsion is carried to cylinder 4 when rotating, the other end processing of cylinder 4 porosely sets an axle, and locating shaft is arranged in bracing frame 3, realizes motor 1, object that reduction box 2, cylinder 4 combine rear symmetrical configuration.3rd gear 6 output also can be other shapes, as rectangle, triangle, other polyhedrons etc.
Specific works process and operation principle as follows:
Caravan with DC driven reducing motor operationally, when motor 1 rotates, the power of motor 1, by rotating with worm gear 12 mating band movable gear shaft 10, is inputed to reduction box 2 by the worm screw 11 being arranged on motor 1 output shaft.
Gear shaft 10 rotates and drives the first gear 7 be arranged on outside it to rotate, the second gear 8 engaged with it is driven to rotate while first gear 7 rotates, second gear 8 drives the 3rd gear 6 to rotate further, because the number of teeth of the first gear 7, second gear 8, the 3rd gear 6 increases successively, thus achieve deceleration.Cylinder 4 is driven to rotate, by cylinder 4 outputting power by its output shaft when 3rd gear 6 rotates.
Now, propulsion plant 9 promotes motor 1, reduction box 2 and cylinder 4 entirety and advances, and cylinder 4 contacts with automobile tire, provides required power by cylinder 4, realizes caravan movement interior among a small circle by tire on the drive wheels.When propulsion plant 9 driving electric machine 1, reduction box 2 and cylinder 4 entirety retreats, cylinder 4 and automobile tire depart from.
