Adopt the automobile-used spare tyre electric elevator of said structure, can drive electrical motor by vehicle power and rotate, thus the electric up-down of realization spare tyre, simple to operate, easy to use, labour intensity is low, high efficiency, time saving and energy saving, spare tyre of lifting only needs less than 2 minutes.Rational in infrastructure, avoided the generation of slide fastener problem, volume is small and exquisite, installs easily.
Description of drawings
Fig. 1 is that the master of the utility model structure looks scheme drawing.
Fig. 2 is the A-A part sectional view of Fig. 1.
Fig. 3 is the birds-eye view of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and principle of work.
As shown in drawings, automobile-used spare tyre electric elevator, it has main shaft (11), main shaft outside is captive nut (29) successively from front to back, by screw thread wheel disc (22) is installed, by screw thread cover (25) is installed, be set with beam barrel (27), be fixed with miniature gears (10), the outside of cover (25) is set with front friction plate (21) successively, ratchet (23), back friction lining (20), the outside of beam barrel is set with fronk rack plate (9) successively, be fixed with hinge axis (19), be set with back frame plate (26), be fixed with gear (15), before, back frame plate is fixed together by pipe link (12), fronk rack plate front side pivotally attached ratchet (24) is installed together with ratchet (23), the bottom of the support (7) that back frame plate rear side is fixing is fixed on the truss (2), by axle (6) and another axle (14) bidentate wheel (5) and another bidentate wheel (13) are installed respectively in the support, the gear wheel in large diameter that two bidentates are taken turns meshes together with miniature gears (10) respectively, small diameter gear on two bidentates wheel respectively with beam barrel on gear (15) mesh together, the hinge wheel (8) that is fixed on the wheel disc passes through chain (4), going up fixing minor sprocket (17) with the axle (16) of electrical motor (3) links together, electrical motor is fixed on the truss (2), and truss is fixed on the base plate (1).
Truss surrounds a rectangular groove, has on the base plate and the cooresponding slotted eye of this groove.By the lifter of base plate, be fixed on the position of the jacking system of the original installation shaking hinge arrangement above the automobile with the utility model.On the appropriate location of base plate, fix a pin.One end is connected hinge on this pin and is stuck in after hinge axis (19) goes up, and the other end is connected on the channel-section steel, after spare tyre is fixed on the channel-section steel, with the channel-section steel hanging below base plate.Electrical motor is a reversing dc motor, and the power supply that joins with it is 12V or the 24V vehicle power on the automobile.
During use, connect the power supply of electrical motor, the minor sprocket (17) on the axle of electrical motor drives hinge wheel (8) by chain and rotates.When the axle forward rotation that makes electrical motor, thereby when driving the hinge wheel forward rotation, wheel disc moves on main shaft backward by screw thread, thereby front friction plate, ratchet, back friction lining are squeezed at cover (25) and go up and locate.Behind the location, wheel disc drives main shaft (11) by cover (25) and rotates, and main shaft and then drive miniature gears (10) rotate.Miniature gears drives the bidentate wheel by the gear wheel in large diameter on the bidentate wheel that is engaged with and rotates.Small diameter gear on the bidentate wheel drives beam barrel (27) by the gear (15) that is engaged with and rotates, and beam barrel drives hinge axis (19) and rotates, and moves thereby drive the hinge that is stuck on the hinge axis.At last, the same with the jacking system of existing shaking hinge arrangement, the hinge that moves just drives the spare tyre that is fixed on the channel-section steel and progressively rises.The hinge that moves up hangs naturally between the pin and hinge axis that connect hinge one end.
The rotation direction of the axle by changing electrical motor, when making the hinge wheel backward rotation, wheel disc moves forward on main shaft by screw thread, presses to nut (29) and locatees, thereby front friction plate, ratchet, back friction lining no longer are crowded together with cover (25).Behind the location, wheel disc drives the main shaft backward rotation, and then drive miniature gears backward rotation, miniature gears drives bidentate wheel backward rotation, bidentate wheeling driving gear (15) backward rotation, gear (15) drives the beam barrel backward rotation, and beam barrel drives the hinge axis backward rotation, hinge axis drives hinge and oppositely moves, thereby realizes the decline of spare tyre.
Obviously, wheel disc should have certain mobile space between nut (29) and cover (25).
Ratchet rotates in the process of wheel disc forward rotation thereupon.The mechanism that the ratchet that is installed together, ratchet are formed makes the ratchet can only forward rotation, can not backward rotation, to prevent in vehicle traveling process, the problem that spare tyre falls takes place.Its concrete structure is identical with existing ratchet and pawl arrangement with principle of work, no longer describes in detail.
Nut is fixed on the front end of main shaft by set pin (28).On the frame plate of pipe link (12) below, track adjusting wheel (18) can also be installed, to play the directional tagging that hinge is moved.
Described hinge wheel (8), minor sprocket (17) also can be the gear that meshes together.The lifter of this structure is by gear transmission, and the rotation of the axle of electrical motor is transferred on the main shaft, further improved the reliability of transmission.
On the bidentate wheel, gear wheel in large diameter, small diameter gear are integral.Adopt minor sprocket to drive hinge wheel, and the purpose that the gear of minor diameter drives gear wheel in large diameter step by step is to reduce the rotating speed of hinge axis.
