Description
Technical field
The utility model is related to the variable-speed unit in power train, is exactly specifically towed variable speed unit.
Background technology
Buncher is a kind of preferable Mechanical Drive Type.Because buncher can provide a series of continuous biographies
Dynamic ratio causes vehicle motor to be worked all the time in high-efficiency point, and this also just improves the efficiency of vehicle and reduces the row of vehicle
Put.Existing various mechanical continuously-variable transmissions can be largely classified into：Friction type stepless speed changer and towed buncher.
For huge discharge internal-combustion engine vehicle, compared to the towed buncher of friction type stepless speed changer transmission efficiency compared with
Height, generally 75%-90%, and the moment of torsion transmitted is larger.Therefore scholars have been obtained in the towed buncher in the field
Extensive concern and research.
Towed buncher refers mainly to drive the rolling of drive element to transmit power using the rolling of active member
Buncher.Towed variable speed unit is the set of primary drive element in towed buncher.Transmission member
Part is rigid, but is frequently not direct contact of the rigid body to rigid body in the place of contact, but forms oil film in centre,
Oil film is viscosity raising under stress, reaches a kind of state of similar solid to transmit larger shearing force.
The loss in efficiency of towed buncher mainly includes：Spin loss, slippage losses, loss of breakking away, bearing are damaged
Lose and churning loss.In general, churning loss, bearing loss proportion are relatively small in towed buncher,
And loss of breakking away just is being produced only in speed change or under other special operating modes, and slippage losses are to be passed completely along with traction
Move and produce, why there are slippage losses, it is this exactly because oil film has certain detrusion in the presence of tractive force
Loss is inevitable.For relatively other all class losses, spin loss proportion in overall efficiency loss is relatively large
Generally 40%-60%, the ratio spinned when the load of transmission is smaller shared by loss is bigger.So-called " spin " refers to pass in traction
Driving link and the driven member speed of each point inconsistent situation in contact area when dynamic, the situation can cause efficiency reduction, oil
The adverse consequences such as film heating, final influence Traction Drive performance.
It is in place of the deficiencies in the prior art：Existing towed buncher is under most working condition, all
Spin loss in efficiency is not avoided that.Cutting for the gyroaxis, the gyroaxis of driven member, traction oil film of driving link is only worked as in spin loss
Plane three could disappear when being parallel to each other or meeting at a bit, and other Traction Drive situations have spin.It is seen that,
Buncher is difficult to take into account spin-free relative geometry position requirement while continuous speed adjustment is ensured.Therefore, it is existing to lead
Drawing formula buncher product has spin to lose.

Axle（2）With output shaft（4）It is θ, sliding block to keep angle（9）It is limited in vertical track（11）In can be along vertical track（11）It is sliding
It is dynamic, roller（10）It is installed in profile modeling rail（12）In can be along profile modeling rail（12）Slide, so as to only need to drive in speed governing
Driven input shaft（2）It is mobile, due to sliding block（9）With roller（10）It is limited in corresponding track, input shaft（2）Do profiling fortune
It is dynamic.
As shown in Figure 2, it is the situation without monocyclic disc type stepless variable-speed unit low speed output of spinning.Such case, input
The ring disk（1）Towards output the ring disk（3）Outer do forming movement, input shaft（2）With output shaft（4）Between angle keep not
Become, and remain input the ring disk（1）With output the ring disk（3）Compress and contact.Due to the relative position relation of actuated element
Change, towing point（7）Position relative export the ring disk（3）Position away from the centre of gyration direction change so that
Gearratio becomes big, low speed output.
As shown in Figure 3, it is the situation without the monocyclic disc type stepless variable-speed unit speedy carding process that spins.Such case, input
The ring disk（1）Phase output the ring disk（3）Center do forming movement, input shaft（2）With output shaft（4）Between angle keep not
Become, and remain input the ring disk（1）With output the ring disk（3）Compress and contact.Due to the relative position relation of actuated element
Change, towing point（7）Position relative export the ring disk（3）Position towards close to the centre of gyration direction change so that
Gearratio diminishes, speedy carding process.
