Description
Technical field
The utility model relates to the driving device of three-wheel or four-wheel electric motor car, a kind of specifically speed change differential rear axle transmission mechanism.
Background technology
Three-wheel or four-wheel electric motor car be because environmental protection, and multiple factors such as easy to use and safety are subjected to people's favor deeply.The structure of existing battery-driven car all is a more complicated, and time of run is limited, and cost is very high
For this reason, the inventor applied for " electric vehicle centrifugal clutch and overrunning clutch coaxial integrated transmission mechanism ", application number on January 22nd, 2009: 200910110937.3 and 200920136470.5 binomial patents.For the associated mechanisms that makes existing battery-driven car can combine with three-wheel or four-wheel electric motor car, so released dependency structure of the present utility model.
Summary of the invention
In order to overcome the deficiency of existing three-wheel or four-wheel electric bassinet structure, the purpose of this utility model is to propose a kind of speed change differential rear axle transmission mechanism on the applicant has applied for the basis of above-mentioned 2 patents.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of speed change differential rear axle transmission mechanism, it is characterized in that: the center shaft of motor rotor stretches on the axle of gearbox body the inner and is connected and installed with the centrifugal clutch spider and centrifugal clutch coils outward, centrifugal clutch is housed on the centrifugal clutch spider gets rid of piece and spring, on the axle sleeve of the outer dish of centrifugal clutch overriding clutch is installed, connect on the overriding clutch axle sleeve outer end and be combined with odontoid belt, the other end of odontoid belt is connected with the back driven pulley, back driven pulley is mounted on the main shaft that speed-change gear box stretches out, the other end of speed-change gear box is connected with the back vehicle bridge, and two terminations of back vehicle bridge are provided with car hoof piece extremely; The other end of back driven pulley is provided with back front driven wheel axle sleeve and spring that is mated and gland, and back driven pulley, back front driven wheel axle sleeve and the spring that is mated thereof and gland all are installed in the diff casing.
Described centrifugal clutch gets rid of piece 2～6.
Described centrifugal clutch is provided with cover in the axle sleeve, in the axle sleeve cover be provided with 2～6 needle bearings between the motor rotor center shaft cooperates.
The described car hoof piece that kills has 2～8.
Slided by needle bearing below motor speed reaches 1000 commentaries on classics during work, centrifugal clutch coils on the axle outward and overriding clutch can not worked.When motor speed reach 1000 utilize more than changeing centnifugal force be contained on the centrifugal clutch spider get rid of piece throw away with centrifugal clutch outside coil to engage to drive and coil an axle rotation outside the centrifugal clutch, the overriding clutch that centrifugal clutch coils outward on the axle is started working, overriding clutch work drives driven stretch pulley work after the odontoid belt transmission that is connected on the belt pulley of overriding clutch shell axle sleeve outer end simultaneously, the driven stretch pulley in back rotates by Pulley shaft and drives the work of speed-change gear box inner gear, thereby realizes wheel.Rotate odontoid belt during overriding clutch work, by driven pulley after the odontoid belt transmission, back driven pulley is by belt pulley elastic tension effect automatic compensation trailing wheel speed.
The beneficial effects of the utility model are: because the utility model has been installed centrifugal clutch and overriding clutch simultaneously on the main shaft that electrical motor stretches out, thereby make it reach integrated.Incorporate mechanism is connected with three-wheel or four-wheeled, promptly can realizes its operation.Therefore, structure of the present utility model is not only simple, reasonable, compact, and the electric current of starting discharge is little, and steadily.Structure of the present utility model can adopt the gear-driven structure of all steel, the maintenance easy accessibility.The utility model combines with the CVT automatic speed changing of prior art, can realize two driving differentia transmission, and moment of torsion is big, and the climbing load-carrying ability is strong.
