Description
Technical field
The present invention relates to the driving device of battery-driven car, a kind of specifically later-model electric vehicle centrifugal clutch and overrunning clutch coaxial integrated transmission mechanism.
Background technology
Battery-driven car is because environmental protection, and multiple factors such as easy to use and safety are subjected to people's favor deeply.And become current industrial a kind of social demand.The structure of existing battery-driven car mainly all is that motor is directly installed on the main shaft of trailing wheel, realizes its operation.Though this structure is simple, it is difficult to have a starting, and power consumption is big, and hill climbing ability is poor, have in addition the implementation of must getting off when going up a slope, and the speed of a motor vehicle waits many shortcomings too slowly.Another battery-driven car is the battery-driven car that is provided with gear case and back axle, this structure utilizes the output of motor to pass to special-purpose back axle again after gear case slows down, to drive the trailing wheel of battery-driven car, this structure is reliable, but has the many shortcomings of thread such as complex structure, heaviness, cost height.
For this reason, the inventor successively applied for " a kind of later-model drive mechanism of electric motor car " and " a kind of later-model battery-driven car acceleration transmission mechanism ", the patent No. (containing application) 200720007028 in 2007 and 2008.3；200710008961。7；200820145749。5 and 200810071877.Four patents such as 4 grades through the production of a year and a half and the use of actual product, are found still more complicated of this structure, need further to transform and improve.
Summary of the invention
In order to overcome the deficiency of existing electric vehicle structure, it is steady to the objective of the invention is to propose a kind of starting on the basis of existing the applicant's patent (containing application), electric vehicle centrifugal clutch that efficiency is high and overrunning clutch coaxial integrated transmission mechanism.
The technical solution adopted for the present invention to solve the technical problems is: a kind of electric vehicle centrifugal clutch and overrunning clutch coaxial integrated 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, on the centrifugal clutch spider centrifugal clutch is housed and gets rid of piece, on the axle sleeve of the outer dish of centrifugal clutch overriding clutch is installed, in the centrifugal clutch axle sleeve cover be provided with needle bearing between the motor rotor center shaft cooperates; The outer dish of overriding clutch is gone up to connect and is combined with odontoid belt, the other end of odontoid belt with after driven pulley be connected, back driven pulley is mounted on the main shaft that speed-changing gear box stretches out, the other end of speed-changing gear box is connected with the battery-driven car rear wheel; The other end of back driven pulley is provided with back front driven wheel axle sleeve and spring that is mated and gland.
Described centrifugal clutch gets rid of piece 2 ~ 6.
Described centrifugal clutch be provided with 2 ~ 6 groups of needle bearings between the motor rotor center shaft cooperates.
Slided by needle bearing below motor speed reaches 1000 commentaries on classics during work, centrifugal clutch coils 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 overriding clutch incrustation belt wheel simultaneously, the driven stretch pulley in back rotates the rear transmission gear box gear by Pulley shaft, and rear transmission gear box gear and rear vehicle shaft gear mesh rotate rear wheel and travel.Rotate odontoid belt during overriding clutch work, by driven pulley after the odontoid belt transmission, back driven pulley is by belt pulley tensioned effect automatic compensation trailing wheel speed.
The invention has the beneficial effects as follows:, thereby make it reach integrated because the present invention has installed centrifugal clutch and overriding clutch simultaneously on the main shaft that electrical motor stretches out.Therefore, structure of the present invention is not only simple, compact, and the electric current of starting discharge is little, and steadily, the present invention simultaneously can prolong the life-span of storage battery and motor and controller, and the efficiency height.Also therefore it is the existing desirable transmission device of battery-driven car.
