Abstract
The invention relates to a continuously-variable transmission. The CVT comprises a box body, an input shaft, an output shaft and an intermediate shaft, wherein the input shaft and the output shaft are arranged in the box body in parallel, and the intermediate shaft is arranged between the input shaft and the output shaft. The output shaft comprises a first transmission shaft and a second transmission shaft. A power input planet gear assembly is connected to the first transmission shaft. A power output planet gear assembly is connected to the second transmission shaft. A driving gear set is fixedly arranged on the input shaft. A transition gear set meshed with the driving gear set and the power input planet gear assembly is fixedly arranged on the intermediate shaft. Because the CVT is not affected by impact of gear shifting, variation of the speed of a vehicle can be more stable, and abrupt stop or abrupt start caused during gear shifting through a traditional automatic transmission is avoided. In addition, the CVT further has the advantages that the weight is light, the size is small and the number of parts is small, power consumption is small due to the transmission mode, so that fuel oil of the vehicle is saved; because the CVT is connected with an engine through a belt, transmission is more stable.
Description
Technical field
The present invention relates to automotive transmission technical field, relate in particular to a kind of gear-driven stepless speed variator.
Background technique
Automobile gearbox common are three types, is respectively hydraulic automatic transmission, mechanical continuously-variable transmission and electric-controlled mechanical automatic speed transmission, and hydraulic automatic transmission has following several shortcoming:
1. pair velocity variations is slow in reacting, is not so good as manual transmission sensitive;
2. excessive fuel consumption, uses uneconomically, and transmission efficiency is low, and torque conversion range is limited, and the more manual vehicle of oil consumption rate exceeds 15-20%.
3. complex structure, maintenance expenses is high.
Electric-controlled mechanical automatic speed transmission has following defect:
1. gearshift poor performance, has obvious pause and transition in rhythm or melody sense during gearshift;
2., on the Safety performance of vehicle, there is certain impact in the power that need to cut off automobile while shifting gears.
Mechanical continuously-variable transmission comprises belt type and ring type stepless speed variator, traditional belt type continuously variable transmission is to utilize planetary gears that the primary input driving force from motor input and the pair input driving force via CVT input are combined, and the driving force after this is synthetic exports driving wheel to, in this buncher, synthetic with the pair input driving force that makes via CVT to input again after the output drive strength speed change of motor by the primary input driving force that the output drive strength of motor is directly inputted, thereby expanded the scope of gear ratio, but this belt type continuously variable transmission still exists speed change unstable, the defect that structure is more complicated.
Summary of the invention
The object of the invention is, in order to solve the existing defect of automotive transmission in prior art, provides a kind of simple in structure, and speed change is steady, the stepless speed variator that rate of fuel consumption is low.
To achieve these goals, the technical solution used in the present invention is:
A kind of stepless speed variator, comprise casing, be arranged on input shaft, the output shaft being parallel to each other in casing and be arranged on input shaft and output shaft between jack shaft, described output shaft comprises the first transmission shaft and second driving shaft, on the first transmission shaft, be connected with power line of input star-wheel assembly, on second driving shaft, be connected with power output planetary wheel assembly;
On described input shaft, be installed with driving tooth wheels, on described jack shaft, be installed with the transition gear group being meshed with described driving tooth wheels and power line of input star-wheel assembly.
Above-mentioned a kind of stepless speed variator, described input shaft is connected with the output shaft of motor by driving component.
Above-mentioned a kind of stepless speed variator, described driving component is belt.
Above-mentioned a kind of stepless speed variator, described driving tooth wheels comprise the first driving gear that is sleeved on input shaft and is parallel to each other, the second driving gear and the 3rd driving gear.
Above-mentioned a kind of stepless speed variator, described transition gear group comprises and is sleeved on jack shaft and is parallel to each other the First Transition gear corresponding with described driving tooth wheels, the second transition gear, the 3rd transition gear and the 4th transition gear.
Above-mentioned a kind of stepless speed variator, described input shaft, output shaft and jack shaft are equipped with shock absorber with the end that described casing contacts.
Above-mentioned a kind of stepless speed variator, described shock absorber is plane bearing.
Beneficial effect of the present invention is: this stepless speed variator impression is impacted less than gearshift, and it is more steady that this just makes the speed of a motor vehicle change, that pause and transition in rhythm or melody sense while there will not be traditional automatic transmission shift.In addition, this CVT is lightweight, volume is little, part is few feature in addition, adds that this type of belt drive power loss is little, and so just for car brings fuel-efficient benefit, CVT is connected with motor by belt, makes transmission more steady.

Embodiment
For making that structure characteristic of the present invention and the effect reached are had and further understand and be familiar with, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1 and Figure 2, a kind of stepless speed variator, comprise casing 1, be arranged on input shaft 2, the output shaft 3 being parallel to each other in casing 1 and be arranged on input shaft 2 and output shaft 3 between jack shaft 4, output shaft 3 comprises the first transmission shaft 5 and second driving shaft 6, on the first transmission shaft 5, be connected with power line of input star-wheel assembly 7, on second driving shaft 6, be connected with power output planetary wheel assembly 8;
On input shaft 2, be installed with driving tooth wheels 9, on jack shaft 4, be installed with the transition gear group 10 being meshed with driving tooth wheels 9 and power line of input star-wheel assembly 7.
Driving tooth wheels 9 comprise the first driving gear 12 that is sleeved on input shaft 2 and is parallel to each other, the second driving gear 13 and the 3rd driving gear 14, transition gear group 10 comprises the First Transition gear 15 that is sleeved on jack shaft 4 and is parallel to each other corresponding with driving tooth wheels 9, the second transition gear 16, the three transition gears 17 and the 4th transition gear 18.
When jack shaft 4 is with input shaft 2 during in separated state, CVT is neutral, when the driving tooth wheels 9 on input shaft 2 are meshed with the planetary wheel carrier of power line of input star-wheel assembly 7 on output shaft 3 by the transition gear group 10 on jack shaft 4, because the planetary pinion in line of input star-wheel assembly 7 is fixedly connected with output shaft 3, planetary pinion drives output shaft 3 rotations, and now, CVT is forward gear, on the contrary, as long as the power input direction of input shaft 2 oppositely can be become CVT to be reversed gear.
