Abstract
The present invention relates to a stepless automatic speed changer with differential gear systems, particularly to a stepless automatic mechanical speed changer. The present invention is formed by combining two groups of differential gear transmission systems. Speed is firstly resolved, and then, synthesized by the present invention. The present invention can realize stepless and automatic speed changes by following the load value and can be applied to mechanical equipment of automobiles, motorcycles, machine tools, etc. which need the speed changes.
Description
The present invention relates to a kind of stepless automated mechanical transmission.
Mechanical speed change is one of device common in the machinery.Existing speed change gear is to adopt to change gear meshing position or employing torque converter and planetary gear set or adopt centrifugal automatic transimission to realize speed change.The disadvantage of these speed change gears is that transmission efficiency is lower, complex structure, complicated operation, can not be with the variation of load stepless automatic transmission.
The purpose of this invention is to provide a kind of simple in structure, transmission efficiency is high, the device of stepless automatic transmission with load variations that need not operate.
The object of the present invention is achieved like this: the driven member that the differential gear power train is decomposed mechanism connects with a driving link of differential gear power train combination mechanism, and another driven member that the differential gear power train is decomposed mechanism connects with another driving link of differential gear power train combination mechanism.The driving link that the differential gear power train is decomposed mechanism is the driving link of whole infinitely variable speed device, and the driven member of differential gear power train combination mechanism is the power output member of whole infinitely variable speed device.Differential gear transmission decomposes mechanism and differential gear power train combination mechanism adopts differential gear train or differential Oscillating Tooth Gear Reducer---differential mobile tooth and small tooth difference planet gear transmission.In differential gear train decomposed mechanism, the three's two as driven member in optional two central gears, the tie-rod, and another is as driving link.In the differential gear train combination mechanism, the three's two as driving link in optional two central gears, the tie-rod, and another is as the driven member of combination mechanism.Decompose in the mechanism in differential Oscillating Tooth Gear Reducer, optional shock wave device, oscillating tooth gear, central gear three two as driven member, another is as driving link.In differential Oscillating Tooth Gear Reducer combination mechanism, optional shock wave device, oscillating tooth gear, central gear three two as driving link, another is as driven member.The driven member that the differential gear power train is decomposed mechanism and a driving link of differential gear power train combination mechanism can be with speedup reverse or constant speed fixed shaft gear train in the same way connect.Power input differential gear power train is decomposed mechanism, the differential gear power train is decomposed mechanism according to the load size, input speed is resolved into two-part, two speed after this decomposes, synthesize a speed by differential gear power train combination mechanism, by the output member output of differential gear transmission system stepless speed variator, thereby finished whole stepless automatic transmission process.
Adopt such scheme, the present invention is simple in structure, and speed change can realize stepless and automatic according to the load size, and transmission efficiency is higher, and can be widely used in automobile, motorcycle, lathe etc. needs in the machinery of speed change.
