Description

A kind of single planetary gear two-shift automatic speed variator of double clutches
Technical field:
The utility model relates to technical field of vehicle more particularly to a kind of single planetary gear two-shift fluid drives of double clutches Device.
Background technique:
Conventional gearbox is as the speed change gear for coordinating engine speed and wheel actual travel speed, for starting The optimum performance of machine.Specifically, since the Rational Rotation Speed section of engine is relatively narrow, revolving speed it is too low then can not output torque, and It can be in a kind of inefficient working condition, so in motion, fuel vehicle needs pass through shift if engine speed is excessively high Reduction ratio is adjusted, so that revolving speed be made to be maintained at reasonable operation interval.For fuel vehicle, without gearbox, vehicle just without Method normally travel.
Electric car is then different, since the working range of motor is wider.The slow-speed of revolution can also be with even under zero speed Export very big torque.I.e., it has no gearbox, electric car can also be run as usual, so electric automobile gear-box Develop more slow.Currently, global mainstream pure electric automobile is substantially all using the framework of motor matching single reduction gear.From structure For upper, single reduction gear does not need gearshift, synchronizer and clutch, and structure is relatively easy and easy to accomplish, therefore is Vehicle enterprise is widely used.
There is the pure electric vehicle of gearbox, more efficient state can be at work.It is previously noted that the work of motor Range is wider, but comparatively, and in the case where middle and slow speed of revolution, the torque of motor is very sufficient, and working efficiency is also relatively high.But In high-revolving situation, the efficiency and torque of motor then can declines rapidly.
Utility model content:
The utility model is to provide a kind of single planet tooth of double clutches to solve the above-mentioned problems of the prior art Two-speed automatic transmission is taken turns, motor is made to be worked as far as possible in efficient revolving speed section, to reach reduction loss, improve in continuation of the journey The effect of journey.
Technical solution used by the utility model has: a kind of double single planetary gear two-shift automatic speed variators of clutch, packet It includes: input shaft, cabinet, planet row, planet carrier shaft, double clutch, output shaft, gear ring, planetary gear, planet wheel spindle, planet carrier, too Sun wheel, first clutch and second clutch;
The sun gear of the planet row and planetary gear external toothing, the planetary gear are connected with planet wheel spindle by bearing, row Star-wheel is freely rotated with respect to planet wheel spindle, and planet wheel spindle rear end and planet carrier are connected, planetary gear and gear ring internal messing;
The gear ring is fixed on box house, and input shaft crosses cabinet, and connects firmly with sun gear;The planet carrier and planet Frame axis front end connects firmly, and planet carrier shaft is hollow shaft, and planet carrier shaft is sleeved on input shaft;
The input shaft passes through bearing phase with cabinet front end, planet carrier shaft and box back and planet carrier shaft and input shaft Even;
First clutch, the second clutch of the double clutch share a drive disk;The output shaft and double clutches The drive disk of device connects firmly, and the driven disc for inputting shaft rear end and first clutch connects firmly, planet carrier shaft rear end and second clutch Driven disc connects firmly;
The input shaft, planet row, planet carrier shaft and output shaft axis are overlapped.
The utility model has the following beneficial effects:
1, vehicle economy is improved
On the one hand, clutch is placed in outside cabinet, reduces gearbox churning loss, imitates planetary transmission itself Rate improves;
On the other hand, it is adjusted by the more gears of speed changer, increases motor work in the chance of high efficient district, to improve The economy of vehicle, increases continual mileage.
2, automatic parking function is realized
When speed changer is in locking state, the automatic parking function of automobile may be implemented.
3, smooth gear shifting is improved
The switching that transmission gear is only realized by the engagement of clutch or separation, improves the ride comfort of shift.
Detailed description of the invention:
Fig. 1 is the schematic diagram of the single planetary gear two-shift automatic speed variator of the double clutches of the utility model.
Wherein:
1 input shaft;2 cabinets;3 planet rows;4 planet carrier shafts;5 double clutches;6 output shafts;7 gear rings;8 planetary gears;9 planets Wheel shaft;10 planet carriers;11 sun gears;12 first clutches;13 second clutches.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
It please refers to shown in Fig. 1, the single planetary gear two-shift automatic speed variator of the double clutches of the utility model, comprising: input shaft 1, cabinet 2, planet row 3, planet carrier shaft 4, double clutch 5, output shaft 6, gear ring 7, planetary gear 8, planet wheel spindle 9, planet carrier 10, Sun gear 11, first clutch 12 and second clutch 13;The wherein sun gear 11 of planet row 3 and 8 external toothing of planetary gear, and Planetary gear 8 has multiple;Planetary gear 8 is connected with planet wheel spindle 9 by bearing, and planetary gear 8 can be freely rotated with respect to planet wheel spindle 9, Each 9 rear end of planet wheel spindle and planet carrier 10 are connected;Each planetary gear 8 and 7 internal messing of gear ring.
Gear ring 7 is fixed on inside cabinet 2, and input shaft 1 crosses cabinet 2, and connects firmly with sun gear 11;Planet carrier 10 and planet 4 front end of frame axis connects firmly, and planet carrier shaft 4 is hollow shaft, and planet carrier shaft 4 is sleeved on input shaft 1.
Input shaft 1 and 2 front end of cabinet, planet carrier shaft 4 and 2 rear end of cabinet and planet carrier shaft 4 and input shaft 1 pass through bearing It is connected.
