On（Clutch need not be installed）, installed in the opposite side of power output shaft, opening and closing spring coordinates with opening and closing disc pacifies opening and closing spring
Dress, Puli's disk are connected by variable velocity zone with opening and closing disc.
Electric car is electric automobile, battery-operated motor cycle or electric bicycle.Synchronizing wheel, which is equipped with, surmounts bearing.Gearbox it is upper
Side cover is equipped with the motor cabinet of installation motor.It is " L " shape arrangement between the axis and power input shaft and power output shaft of driving wheel, straight
Random angle form is arranged between linear arrangement or 90 °~270 °.
In order to reach the using effect of the utility model, variable part is assembled with CVT driving parts.For can be smooth
Installation and reduction are to the occupancy of inner space, the carry out rational deployment to parts installation site.To reduce whole component
Size, two axis of power input shaft and power output shaft are tried one's best close, and select suitable V-type variable transmission belt.
To reduce unnecessary no-load current consumption, surmount bearing in input end of motor installation, wheel is not increased when sliding
Add extra resistance.The characteristics of due to motor power itself, without idling, save clutch.Power output shaft is defeated with power
Go out opening and closing disc to be connected together, rotated for motor and directly drive trailing wheel, not extraneoas loss power, can increase by 30% it is continuous
Navigate mileage.Power output direction can be adjusted according to design requirement of vehicle or so, achieve the purpose that integration, make power source with becoming
Fast transmission case links together, and forms compact-sized variable-speed transmission system for electrocar.When gear-box side cover board is designed
The motor cabinet of installation motor is added, motor is really merged with stepless gear system after installing, is formed
One integrated member.Vehicle realizes modularized design, reduces the assembling link of vehicle.Variable speed input terminal uses Puli
Disk, extrudes Puli's disk using Puli pearl during rotating speed increase, the distance between Puli's disk is diminished under the influence of centrifugal force, so that
Speed belt is extruded progressively close to the cylindrical of Puli's disk.Opening and closing disc is then since preceding Puli's disk drive diameter becomes larger then in speed belt
Pulling force under progressively diminish, achieve the purpose that speed change.Motor passes through primary speed-down when speed change system is entered, due to drop
The low rotating speed for entering variable speed input terminal, for the actual weight of Puli pearl, is recalculated, makes Puli pearl in 0-
Centrifugal force between 4000 turns reaches the gear requirement of the utility model.It can be replaced according to the use environment of normality different
The Puli pearl of weight obtains the performance of different vehicle.
The electric car that the utility model is designed using brushless high speed external rotor electric machine as power source combination CVT technologies
Variable transmission assembly, using high-power brushless external rotor electric machine, opening and closing disc is directly installed on power output shaft and eliminates
Clutch, improves electric automobile driving and transmission efficiency, low and handling good with light-weight, transmission efficiency, power consumption
Advantage.

Embodiment
The utility model is described in detail with reference to embodiment and attached drawing.Scope of protection of the utility model is not limited to
Embodiment, those skilled in the art make any change in the range of claim restriction and fall within the utility model protection
Scope.
Embodiment 1
The utility model electric car variable transmission assembly as shown in Figure 1, Figure 3, including gearbox 15, motor 1, actively
Wheel 5, synchronizing wheel 6, opening and closing disc 7, Puli's disk 9, moving bead disk 10, opening and closing spring 12, power input shaft 11 and power output shaft 8.
As shown in Fig. 2, the upper side cover 3, lower side cover 2 and the protecgulum 4 that are equipped with outside the babinet of gearbox, upper side cover 3 is equipped with installation motor
Motor cabinet, motor are installed on motor cabinet, and motor is brushless high speed external rotor electric machine.Motor is coaxially connected with driving wheel, actively
Wheel is connected by conveyer belt 13 with synchronizing wheel, and synchronizing wheel 6, which is equipped with, surmounts bearing.Synchronizing wheel, Puli's disk and moving bead disk are coaxially pacified
On power input shaft, moving bead disk coordinates with Puli's disk to be installed.Opening and closing disc is installed on power output shaft, opening and closing spring peace

Big output torque overcomes resistance, reaches the effect of the power saving in startup or climbing.2. using powerful outer rotor at a high speed
Brushless electric machine is used as power source, and efficient up to 95%, no-load current is small, reaches the inaccessiable using effect of traditional electric car motor.
3. using after high-power external rotor brushless high-speed electric expreess locomotive+stepless gear system, acted on the premise of same voltage is with power
Peak torque onboard is 3 times of wheel hub motor or the direct-connected transmission of common built-in motor.4. compact overall structure, occupied space
Compared to direct-connected transmission is small compared with being put in same power, controller occupies little space, and more batteries can be installed, to increase vehicle
Course continuation mileage.5. similarly configure it is constant in the case of, use the utility model variable transmission assembly, replace different weight
Puli pearl or replace opening and closing disc opening and closing spring, the vehicle with regard to different performance can be obtained.Puli pearl is more heavy-tailed, and speed is higher, general
Lighter more suitable, the more power saving that starts to walk of sharp pearl.Similarly the more light then tail speed of the spring force of opening and closing disc is faster, and the spring force of opening and closing disc is got over
It is big then start to walk faster.
