Description

The multispeed motor wheel hub

The utility model relates to transportation machinery, especially the land speed-variating hub mechanism of battery-driven car.

Electric wheel hub is mainly used in bicycle, three-wheel vehicle, motor bike and automobile, gasoline car can be eliminated gradually because of its consumes energy and environmental pollution, come the instead of gasoline car with battery-driven car, it is the target of the world today, but the electric wheel hub that uses in the world is single speed at present, these single speed wheel hubs can only use on the level land, running into the situation of going up a slope or blowing just can't travel, because it does not have variable moment of torsion to adapt to above-mentioned situation, thereby moving velocity is sharply descended, power consumption increases, and electrical efficiency reduces; Secondly, because housing structure is unreasonable, in operational process, lack waterproof, antifouling property.

The purpose of this utility model is to avoid the defective of prior art and provides a kind of volume little, and is in light weight, the power consumptive province, and output torque is big, and electrical efficiency is high and adapt to all over the world by speed change that the multispeed motor wheel hub of different terrain needs is first purposes; Adopting rational housing structure is second purpose of the present utility model with raising waterproof, antifouling property.

The purpose of this utility model realizes by following technical proposal: be provided with a left side fastened to each other in housing, right fixed mount, respectively with a left side, right axle shaft is fixed and is connected with vehicle by it, the driving gear that is provided with fixing motor and is in transmission connection in the fixed mount of a left side with motor output shaft, be provided with the driven shaft that is bearing in the bearing in the right fixed mount, driven gear on the axle and driving gear engagement, it is characterized in that described driven shaft mouth is provided with a plurality of teeth, simultaneously respectively with a plurality of gears mesh, between a plurality of gears and a plurality of star-wheel, be provided with overriding clutch separately, a plurality of star-wheels are in transmission connection with the shared constellation that is connected housing again, the effector of handling overriding clutch is located on the right axle shaft, make many grades of gears on a plurality of power-transfer clutchs form mutual overtaking under the effect of effector, the type of drive of skidding, make housing obtain different output speeds, adapt to the needs of different terrain all over the world thereby reach, reach the fastest level land moving velocity and best upward slope climbing power with speed change.

Described housing is made up of disjunctor hub fastened to each other and lid, connects faying face to reduce as far as possible.

The utility model compared with prior art, because this device is provided with many group variable gears, by the exportable many grades of rotating speeds of the control of effector, so can increase output torque greatly in the time of at a slow speed, reach best climbing power, and reach optimal level land speed per hour fast the time, to adapt to the operation needs of different physical features all over the world; Be installed in the rational housing because of the speed change wheels simultaneously, reduced the bonded assembly faying face, so have strong waterproof, antifouling property.

Description of drawings.

Fig. 1 is the utility model embodiment 1 structural representation.

Fig. 2 is the utility model embodiment 2 structural representations.

Fig. 3 is a kind of overriding clutch organization plan scheme drawing.

Fig. 4 is another kind of overriding clutch organization plan scheme drawing.

Below in conjunction with above-mentioned accompanying drawing embodiment of the present utility model is remake and to elaborate.

Shown in Fig. 1-4, the housing of multispeed motor wheel hub is combined by disjunctor hub (2) fastened to each other and lid (7), and disjunctor hub seam and bearing hole when Vehicle Processing once bore, and mix good lid, have improved the concentricity of wheel hub greatly.

Be provided with left and right fixed (3), (5) of one fastened to each other in the housing, fix with left and right half (1), (26) respectively, left and right half is separately fixed on the electromobile frame, and housing is connected with wheel by width of cloth bar.Be fixed in the left fixed mount (3) with nickel-cadmium cell or battery-driven motor (4), motor output shaft is provided with key bonded assembly driving gear (25), be provided with the driven shaft (23) that is bearing in the bearing (22) in the right fixed mount (5), the driven gear on the axle (24) is driven by driving gear with the driving gear engagement and does contrarotation.

The driven shaft mouth of embodiment 1 (referring to Fig. 1, as follows) is provided with 2 connecting shaft axle teeth, and promptly axle tooth I (21) and axle tooth II (20) are exported 2 grades of rotating speeds.The connecting shaft axle tooth of embodiment 2 (referring to Fig. 2, as follows) comprises a tooth I (21), axle tooth II (20), axle tooth III (31), exports 3 grades of rotating speeds.With the corresponding respectively simultaneously ingear of axle tooth is gear I (19), gear II (18) or gear I (19), gear II (18), gear III (30), the type of drive that this gear forms mutual overtaking, skids by overriding clutch with cooresponding star-wheel again.Star-wheel has star-wheel I (17), star-wheel II (16) or star-wheel I (17), star-wheel II (16), star-wheel III (29), star-wheel is connected with shared constellation (15) key, constellation (15) is connected with lid (7) minus thread in the housing or key connects or pin connects, present embodiment adopts minus thread to connect, and making changes tight more more in rotary course.

Overriding clutch comprises on the outer circumference surface of the star-wheel that combines with bore and has 3 uniform grooves and hole, is provided with roller in the groove, is provided with the spring that acts on the roller in the hole.The roller of embodiment 1 has roller I (6), roller II (8), and the roller of embodiment 2 has roller I (6), roller II (8), roller III (27), and corresponding spring has spring I (32) and spring II (33).

Before a kind of overriding clutch between star-wheel and shared constellation, also be provided with the thin bar (9) that radially slides, the slip of this thin bar is controlled by variable-speed manipulator.

Described effector comprises and is located in the right axle shaft (26) the manually joystick of passing activity (13), be sleeved on the cover on the right axle shaft, press in the cover and the pin (12) that in right axle shaft Long Circle groove (10), can pass and the retracing spring (11) that pin is resetted.

Described cover two chamfers can be the tubular casing I (14) of scheme 1 or the ladder tubular casing II (28) of scheme 2.

The utility model is when the needs speed change, promotion joystick and then pushing pin drive the cover I or the cover II moves in the Long Circle groove of right axle shaft, make cover I or the thin bar of cover II jack-up, the roller of overriding clutch is just shifted onto broad position, gap by thin bar, make gear I and star-wheel I release the drive relation, the slow shelves output of wheel hub.When joystick is not pushed into, be depicted as fast shelves output as the embodiment 1 of Fig. 1, though this moment, the gear II also was in power delivery status with the star-wheel II, because of gear I speed greater than the gear II, so formation speed surmounts, wheel hub is exported for fast grade.

Embodiment 2 principles are identical, when thin bar is in Fig. 2 state, are fast shelves output, when the thin bar of two power-transfer clutchs was on the same ladder of tubular casing II, the middle-grade output of wheel hub continued to promote joystick, when two thin bars were on the different ladders of tubular casing II respectively, wheel hub was slow shelves output.
