Abstract
The utility model discloses a wheel hub type variable speed clutch which has simple structure, small volume and stable and reliable working and is integrated with the functions of the clutching and variable speed. The wheel hub type variable speed clutch comprises a planetary carrier arranged on a wheel hub, a power shaft, a clutch slip, a sun wheel and an offsetting spring, wherein, the power shaft, the clutch slip and the sun wheel are sequentially connected with the planetary carrier in a mutual matching way, and the offsetting spring is arranged between the power shaft and the clutch slip; the sun wheel is arranged on a planetary wheel on the planetary carrier and meshed with an inner gear on the wheel hub; and one end of the planetary carrier is respectively provided with a cam, a post rod corresponding to the clutch slip and a post pin corresponding to the cam and the post rod.
Description
Technical field
The utility model relates to a kind of hub-type speed change clutch.
Background technology
Usually the velocity of rotation that the rolling master brush of pickup sweeper need be opposite with the pickup sweeper direct of travel and speed is directly proportional.Existing pickup sweeper is owing to its reasons in structure, and its cleaning is difficult to reach harmonious with walking.Clearing apparatus and running gear speed change and drive mechanism disperse and more complicated, cause car load bulky, use maintenance inconvenient, and the speed change arrangement of clutch of clearing apparatus exposes, and dust causes harmful effect to parts during work, inefficiency.
The utility model content
The purpose of this utility model is to provide a kind of hub-type speed change clutch at the deficiency that above-mentioned prior art exists.This hub-type speed change clutch is simple in structure, and clutch speed-changing is integrated, and volume is little, is convenient to maintenance.
The technical solution of the utility model comprises pinion carrier, be located at cooperatively interact successively bonded assembly dynamical axis, clutch-plate, sun wheel and be located at retracing spring between this dynamical axis and the clutch-plate on this pinion carrier, described pinion carrier is connected on the wheel hub, described sun wheel is through being located at the satellite gear and the inner gear engagement of being located on this wheel hub on the pinion carrier, and an end of described pinion carrier is respectively equipped with cam, corresponding to the push rod of described clutch-plate and the pin that is connected in this push rod corresponding to described cam.
Described push rod is located on the through hole of offering on the described pinion carrier or counterbore.
Described clutch-plate and sun wheel green phase are mutually to corresponding set some projections respectively with groove is corresponding is connected; Described clutch-plate is sheathed on the described dynamical axis by the set counterbore of one side.
The sidewall of described cam be provided with along its radial direction protrude protruding
One end of cam is provided with its bottom surface and is the bevelled special impression, and described pin is connected in push rod corresponding to the special impression of described cam.
The utility model utilizes the wheel hub shell and the end cap of wheel hub electric motor of electric vehicle, and sun and planet gear is set therein, adds the power-transfer clutch of available manipulation flexible axle control, forms osed top speed change clutch transmission; The transmission of power that ground is passed to wheel to dynamical axis so that its rotation direction is opposite with wheel, improve the output chain gear rotating speed and make it to be directly proportional with the wheel speed of travel, to obtain the needed propulsive effort that makes of clearing apparatus, can cut off takeoff output again when needed.Simple in structure, volume is little, be convenient to safeguard, and high efficiency, and still can reliable and stable work in the cleaning environment of many dusts.
Description of drawings
Fig. 1 is the utility model structural representation.Fig. 2 is Fig. 1 cam structural representation.
The specific embodiment
Now also the utility model is described in further detail in conjunction with the accompanying drawings by embodiment.As shown in Figure 1 and Figure 2, pinion carrier 6 its two end axles are movably connected on the two end cap of wheel hub 2 through bearing arrangement.Dynamical axis 10 is movably connected on the end axle of pinion carrier 6 through bearing arrangement.Clutch-plate 9 is positioned at pinion carrier 6 inboards and is located at inboard one end that counterbore 4 on the axis is movably set in dynamical axis 10 by it.Retracing spring 15 is sheathed on the dynamical axis 10 between the protruding annular table of clutch-plate 9 one ends and dynamical axis 10.The sun wheel 8 that is movably connected on the medial extremity of pinion carrier 6 one end end axles through bearing arrangement flexibly connects by the mutual corresponding matching of two projections set on set two grooves on its end face and clutch-plate 9 corresponding end-faces, and the satellite gear 7 of sun wheel 8 through being fixedly arranged on relative both sides on the pinion carrier 6 is meshed with inner gear 3 on being fixedly arranged on wheel hub 2.
Claims (4)
