Abstract
The utility model relates to a continuously variable transmission (CVT). The continuously variable transmission comprises a box body, an input shaft and an output shaft which are parallel to each other inside the box body, and an intermediate shaft arranged between the input shaft and the output shaft, wherein the output shaft comprises a first transmission shaft and a second transmission shaft; the first transmission shaft is connected with a power input planet wheel assembly; the second transmission shaft is connected with a power output planet wheel assembly; the input shaft is fixedly provided with a driving gear set; the intermediate shaft is fixedly provided with a transition gear set meshed with the driving gear set and the power input planet wheel assembly. The continuously variable transmission cannot feel the impact of shifting, thus the vehicle speed variation is more stable, and a jerking sense when a traditional automatic transmission shifts gear cannot occur. Moreover, the CVT has the characteristics of light weight, small size and few components, and the transmission mode is low in power consumption, as a result, vehicles are more fuel-efficient; the CVT is connected with an engine through a belt, so that the transmission is more stable.
Description
Technical field
The utility model relates to automotive transmission technical field, relates 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 when gearshift;
2., there is certain impact to the Safety performance of vehicle in the power that need to cut off automobile while gearshift.
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 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 expand the scope of gear ratio, but this belt type continuously variable transmission still exists speed change unstable, the defect that structure is more complicated.
Model utility content
The purpose of this utility model 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 adopted in the utility model 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 the First Transition gear corresponding with described driving tooth wheels that be parallel to each other, 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.
The beneficial effects of the utility model are: 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 effect of reaching are had and further understand and be familiar with, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, 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, in the time that the driving tooth wheels 9 on input shaft 2 are meshed with the planetary wheel carrier of the 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 to rotate, 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.
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.
