Abstract
The utility model relates to a double-driving miniature tricycle rear bridge. The middle of the existing single driving miniature tricycle rear bridge is provided with a differential mechanism, and a transmission sprocket wheel (10) is fixed to a right half casing of a differential mechanism casing (9). The differential mechanism is connected with a left half shaft (3) and a right half shaft (8) which are arranged in a bridge casing (4), and the lateral surface of a dust preventing automatic disk (2) is carved with a dust preventing groove C. Thus, the double-driving miniature tricycle rear bridge is made.
Description
The utility model relates to a kind of improved tricycle rear axle, especially a kind ofly is used for miniature motor-driven tricycle rear axle.
Tricycle rear axle is the main portion of three-wheel vehicle driving system, is used to the wheel transferring power.Existing bubble car back axle all is single drivings, it is the wheel that transferring power only passes to the three-wheel vehicle trailing wheel, drive by this wheel turns and to sail three-wheel vehicle and travel, there is following defective in this single tricycle rear axle that drives in practicality: the one, and not steady because monolateral driving is travelled, chaufeur labour intensity is big; The 2nd, do not link to each other because of a wheel when turning with power system, not controlled by power system, overturn easily; The 3rd, when the wheel that is not subjected to power system control is in pit,, cause this wheel not change because of its unpowered driving, car does not go out the hole.
The purpose of this utility model provides a kind of two bubble car back axle that drives, and utilizes this two bubble car back axle transferring power that drives, and can overcome above-mentioned single deficiency that the bubble car back axle exists that drives.
The purpose of this utility model is achieved in that
A fast device of fork is installed in the middle of the bubble car back axle, pitching fast device is connected with the left and right sides semiaxis of back axle, pass to the power of the fast device of fork from driving system, be assigned to left and right sides semiaxis by the fast device of fork, make the left and right sides semiaxis of back axle simultaneously stressed, thereby two drivings are connected in two wheels of back axle, reach producing balanced forces and travel.
The utility model is because a fork speed device that links to each other with bubble car back axle left and right sides semiaxis only is installed in the middle of the bubble car back axle just can be realized, thereby structure is very simple.After bubble car used this back axle, two trailing wheel is driver under stress simultaneously, operates steadily, and reduced chaufeur labour intensity in travelling, be difficult for overturning, and can normally operation in muddy highway.
Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing.
Fig. 1, existing single structural representation that drives the bubble car back axle.
The semi-sictional view structural representation of Fig. 2, the utility model embodiment.
As shown in Figure 1 and Figure 2,1 among the figure is the terraced piece of brake, and 2 among the figure is dustproof arresting discs, and the dustproof arresting disc 2 and the terraced piece 1 that brakes are fixed on the two ends of axle housing 4 symmetrically.Among the figure 3 is left half axles, and 4 among the figure is axle housings, and 7 among the figure is bearings, and bearing 7 links to each other with axle housing 4, and 8 among the figure is right axle shafts.Left half axle 3 and right axle shaft 8 are installed in the axle housing 4, and can convenient rotation in axle housing 4.On right axle shaft 8, be fixed with driving chain wheel 10, constituted existing bubble car list driving rear axle.The utility model is that the fast device of a fork is installed in the axle housing 4 between left half axle 3 and right axle shaft 8, makes two bubble car back axles that drive.Pitching fast device is made of the symmetrical gear of two couples in fast device shell 9 of fork and the shell 9.The shell 9 of pitching fast device is divided into left and right sides two parts, has part movable sprocket 10 on right half shell, is equipped with screw on left half shell, with bolt driving chain wheel 10 is fixed on left half shell, constitutes the fast device shell 9 of whole fork.In the fast device shell 9 of fork, two pairs of gears are installed symmetrically.Wherein a pair of star gear 5 is worn by the star gear wheel shaft and is connected together, and the star gear wheel shaft is fixed on a left side half shell of the fast device shell 9 of fork.Star gear 5 combines with the between cog of the axle side gear 6 that symmetry is installed, axle side gear 6 is axially installed with left half axle 3 and right axle shaft 8, the spline of axle side gear 6 penetrates in the keyway of right axle shaft 8 of left half axle 3, when power drives driving chain wheel 10 rotations, star gear 5 rotates with the shell 9 of the fast device of fork, because the tooth of star gear 5 combines with the tooth of axle side gear 6, thereby driving axle side gear (6) rotates together, make left half axle 3 and right axle shaft 8 rotate simultaneously, realized the purpose of this utility model.Be carved with dustproof groove C in the side of dustproof arresting disc 2, the limit of the car hoop that brakes outward can enter in the groove, and brake system is sealed, and prolongs the service life of brake system.
Claims (3)
1, a kind of two bubble car back axle that drives, it contains an axle housing (4), be fixed with brake terraced piece (1) and dustproof arresting disc (2) symmetrically at the two ends of axle housing (4), left half axle (3) and right axle shaft (8) are installed in axle housing (4), the center fixed of axle housing (4) has bearing (7), driving chain wheel (10) is fixed together with right axle shaft (8), it is characterized in that: described two bubble car back axles that drive are that a fast device of fork is installed in the middle of axle housing (4), driving chain wheel (10) is fixed on the right side half shell of the fast device housing of fork (9), pitch fast device and link to each other with right axle shaft (8), make two bubble car back axles that drive with left half axle (3).
2, by the described two bubble car back axles that drive of claim 1, it is characterized in that: the fast device of described fork by about the fork speed device housing (9) formed of two and half shells, and the gear of the symmetry of two couple in the housing (9) installation assembles,
3, by the described two bubble car back axles that drive of claim 1, it is characterized in that: dustproof groove C is carved with in the side of described dustproof arresting disc (2).
