Abstract
The utility model belongs to a transmission mechanism for driving the wheels of the mini-car, which is the transmission mechanism for wheel rim capable of realizing to advance, slide, reverse and change speed. The transmission mechanism is composed of a central gear driven by a regulating motor, a passing wheel, an inner gear, a ratchet wheel sheathed outside the inner gear and matched with the pawl of the inner gear and a clutch mechanism between the inner gear and the ratchet wheel which is connected onto the wheel rim. When the motor is positively rotated, the inner gear is driven to positively rotate, and the pawl and the ratchet wheel drive the car wheels to advance, and when reversing, the inner gear is connected with the ratchet wheel through a clutch, then the motor is reversely rotated, and the inner gear is reversely rotated, then the car wheels are reversely rotated through the clutch and the ratchet wheel.
Description
The utility model belongs to the wheel rim transmission device of the transmission device of powered vehicle, particularly a kind of electrically operated lilliput car.
Existing mid-get car all adopts engine output power, comes drive wheels by mechanical transmission mechanism again, and its messenger chain is longer, and occupation space is bigger, causes the micro-miniaturisation of vehicle and occupant's free space all will be subjected to certain limitation.
It is shorter that the purpose of this utility model provides a kind of messenger chain, and occupation space is little and can realize advancing, fall back, slide and the global function wheel rim transmission device of speed change of wheel.
The solution that realizes the utility model purpose is: the sun gear that the wheel rim transmission device that is provided is driven by buncher, inner gear, with sun gear and inner gear ingear third wheel, cover large internal gear outward and and inner gear on the ratchet of click-fit and the engaging and disengaging gear between inner gear and ratchet form, wherein ratchet and rim for automobile wheel link.When motor just changes, drive inner gear and rotate by sun gear, third wheel, the ratchet on the inner gear combines with ratchet, drive ratchet and rotate, thereby drive wheels is advanced.Owing to connect by ratchet, ratchet between wheel rim and the inner gear, make automobile slide so wheel can surmount inner gear.When needs are moveed backward, handle engaging and disengaging gear, inner gear is connected with ratchet.Motor counter-rotating then makes the inner gear counter-rotating, and inner gear drives the ratchet counter-rotating by engaging and disengaging gear.
Above-mentioned engaging and disengaging gear is by connecting firmly large internal gear one side and have floral disc, the ratchet side projection of breach, can form with the ring-type car backing apparatus that chimeric clutch discs, clutch discs push rod, clutch discs retracing spring and the side of floral disc breach and ratchet side projection has a V-notch relative with push rod.When not moveing backward, clutch discs is separated with ratchet with floral disc.During reversing, handle car backing apparatus and rotate, the inclined-plane of car backing apparatus V-notch promotes push rod and moves, and push rod promotes clutch discs again and moves, and clutch discs and floral disc and ratchet are linked together.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is an axial view of the present utility model.6--bumper among the figure.
Fig. 2 is the cutaway view at Figure 1A-A place.7--back-up ring among the figure, 8--former, 15--bearing cap shim, 17--brake shoe brake cheek.
Fig. 3 is the three-dimensional view of car backing apparatus.
Fig. 4 is the three-dimensional view of clutch discs.
Fig. 5 is the three-dimensional view of floral disc.
Fig. 6 is the three-dimensional view of ratchet.
As shown in Figure 1 and Figure 2: buncher 14, be contained in the motor casing 18, sun gear 2 is contained on the axle of motor 14.Third wheel 1 has three, and it is contained in the elongated end of motor casing 18.The periphery of inner gear 5 is provided with three ratchets 4, and ratchet 3 is linked together by six splines on its periphery and rim for automobile wheel 9.Therefore, when motor 14 driving center gears 2 were just changeing, through third wheel 1 driven gear 5, the ratchet on the inner gear 5 was passed to ratchet 3 with power, and spline on the ratchet 3 and wheel rim 9 effects transmit moments of torsion, and wheel is rotated forward.When turning off motor or descending, ratchet 4 does not play a part to transmit moment of torsion, and wheel and transmission device are freed, vehicle slides forward.
The side of large internal gear 5 is connecting firmly a floral disc 10, its structure as shown in Figure 5, the endoporus of floral disc 10 has 12 breach.The structure of ratchet 3 as shown in Figure 6, its periphery has six claw-like projections 31 that extend laterally, between six splines 32 of ratchet 3.Be provided with a clutch discs 11 in the side of floral disc 10 and ratchet 3, its structure as shown in Figure 4.The side of clutch discs 11 is provided with 12 and protrudes piece 11a, and periphery has six breach 11b.After clutch discs 11 moved to left, its breach that protrudes piece 11a and floral disc 10 was chimeric, and the claw-like projection 31 of its breach 11b and ratchet 3 is chimeric, thereby floral disc 10 and ratchet 3 are linked up.The structure of car backing apparatus 13 as shown in Figure 3, it be one the band handle annulus, its end face has six V-notchs.Six push rods 12 are between clutch discs 11 and car backing apparatus 13V v notch v.Handle car backing apparatus 13 during reversing and rotate, push rod 12 is pushed away V-notch and is moved to left, and push rod promotes clutch discs 11 again and moves to left, and floral disc 10 and ratchet 3 are tied.Motor 14 counter-rotatings then, inner gear 5 counter-rotatings drive ratchet 3 counter-rotatings through floral disc 10, clutch discs 11, make wheel reversing.When the car backing apparatus return, clutch discs 11 resets under the effect of spring 16.
Compact conformation of the present utility model, volume is little, and whole transmission device can be contained in the space of wheel central authorities.Use the form of its driving engine of vehicle of this transmission device to choose wantonly, as long as can drive electrical generator, and the installation site is also unrestricted, has saved middle complicated mechanical drive mechanism, thereby can simplify body structure, and can provide bigger space to the occupant.
