Continuous transmission ratio make vehicle motor be in always high-efficiency point work, this just greatly improves the efficiency of vehicle, reduce
Vehicle discharge, has the function that energy-saving and emission-reduction.CVT has the characteristics that power is high, oil consumption is low, discharge is few, according to statistics, uses
The automobile ratio of CVT reduces 7%-15% using the automobile fuel consumption of automatic transmission (AT), and exhaust gas discharge reduces about 10%, production cost
Reduce 20%-30%；And the oil consumption of the hybrid electric vehicle of CVT power train is used to be likely to reduced 30%, discharge can reduce 45%.It is towed
CVT has the characteristics that power density is high, high-efficient, transmitting power is big, it will the development side as the following stepless transmission technology
To.Therefore, towed CVT technology has been widely studied in developed countries such as Japan, Britain, the U.S..
In general, the loss in efficiency of towed CVT specifically includes that spin loss, slippage losses, loss of breakking away, bearing
Loss and churning loss.Wherein sideslip loss, churning loss, bearing loss are relatively small, and loss of especially breakking away only is becoming
It is just being generated when fast or under other special operating conditions, and slippage losses are this damages generated completely along with Traction Drive
Mistake is inevitable.For other opposite all class losses, spin loss proportion is relatively large, generally 40%-60%, when
The shared ratio of spin loss is bigger when the load of transmission is relatively small.The generation of spin is due to drawing in Traction Drive
Element with it is uneven by the VELOCITY DISTRIBUTION of traction element and caused by.In general, scholars often think this spin loss
In gear range be can only reduce to the greatest extent it is not eliminable.Due to the obstruction of spin, in towed CVT, transmission efficiency
It generally can only achieve generally 75%-90% after optimization, further being promoted will become abnormal difficult, this is also greatly lowered
The application range and transmission capacity of towed CVT.Eliminate spin can also improve Traction Drive operating condition (reduce oil temperature,
Improve oil film asymmetry etc.), to reduce other types of loss, the maximum delivered of towed CVT can also be properly increased
Torque.In addition spin is eliminated in certain gear range, and whole transmission efficiency at least 5% can be improved.
For the towed CVT design that spin is eliminated, i.e., described designs this problem without the towed CVT that spins, existing
In some technical solutions, resolving ideas is given using towed CVT research team, Sichuan University as representative, i.e., from without spin condition
It sets out, using the bus equation of the method optimization driving member of the differential equation, gear etc. is redesigned, so that leading after optimization
Draw formula CVT structure to meet without spin condition.The Chinese patent CN104776180A of team application discloses a kind of without spin change
Fast unit, the program have carried out the bus optimization of cone disk, have obtained optimization method, and limit tune by taking the towed CVT of semi-ring surface as an example
Input cone disk and output cone disk are moved axially along rotating shaft during speed, and idler wheel is moved radially along rotating shaft, to realize without spin
Transmission.The deficiency of the program is: only give bus optimization as a result, not providing actual gear, loading mechanism
Structure feature；Speed adjustment unit described in the program is the transmission scheme of coaxial class, for some spies for requiring to use parallel axes
Different occasion is no longer on probation, needs to increase complicated switching mechanism and is just able to achieve.

Common normal three line in person contact point is met at a bit always, is realized and is driven without spin.
(2) when speed change: variable speed electric motors, particularly drives lead screw rotation in gear, and lead screw drives nut to move axially along,
And speed change rocking bar is driven to rotate around the hinge joint of shifting sleeve interlude jointly by ut socket and roller, and then in drive
Between input terminal idler wheel in transmission parts and output end idler wheel rotated around the hinge joint of shifting sleeve interlude；Rotation process
In, due to the limitation of input terminal translation sleeve and output end translation sleeve so that input terminal roller shaft and output end roller shaft it
Between coaxially slide, while the edge cam loading mechanism of input terminal and output end force input cone disk and output bore disk along respective
Axis of rotation is mobile, to guarantee to input cone disk and input terminal idler wheel in new point pressure close contact, output cone disk and output end
Idler wheel is also in new point pressure close contact.Then, input cone disk and the contact radius of output cone disk can change correspondingly, stepless change
The transmission ratio of fast device also changes correspondingly, and realizes speed-change process.
A kind of parallel axes of the present invention is without the beneficial effect for the towed stepless transmission that spins:
(1) input shaft is installed with output shaft to be parallel in the present invention program, is overcome coaxial towed stepless transmission and is used
The deficiency that additional complicated transmission switching mechanism is needed when parallel axes occasion, is used directly for parallel axes application.
(2) realize and be driven without spin: the disk of input cone described in the present invention program, output cone disk have been all made of and have optimized without spin
Equation, the ingehious design of gear in addition, so that input cone disk axis of rotation, input terminal idler wheel axis of rotation are contacted with the two
Point three line of common normal is met at a bit always, output cone disk axis of rotation, output end idler wheel axis of rotation and the two contact point public law
Three line of line is met at a bit always, be ensure that and is driven without spin, improves the transmission efficiency of towed CVT.
(3) reasonable loading mechanism and gear: present invention employs edge cam loads and two kinds of sides of spring loads
Formula realization is axially loaded, ensure that the normal force of cone disk and roller contact point.Both loading methods constitute seal force load system
System, the mechanism closure of gear in addition, also can again speed change when give and load, this just greatly improves load reliability.
In addition, present invention employs sleeve, rocking bar and the gear of worm drive, mechanism is simple, facilitates realization；And worm drive are adopted
With ball-type, frictional force is small, moreover it is possible to realize it is self-locking, for keeping speed change and gear ratio being kept to have better effects.
