Set forth a kind of parallel axes in the US Patent No. 1709346 and be inverted the conical ring stepless speed changes devices that encircles transferring power and speed change between awl utilization awl mutually.Positive and negative output rotation and compact structure for implement device often have the use supporting with it of simple single planetary row.Along with development of modern industry, some field all proposes high requirement to volume, weight, the gear ratio coverage area of speed change gear.Such as some vehicle, require the volume of speed change gear little, in light weight, the gear ratio coverage area is big, to satisfy the requirement of car load power character, Economy.Only depend on the adjustment of conical ring speed change gear itself, can realize the requirement of gear ratio coverage area, but volume, weight will obviously increase.Simple single planetary row can be realized the requirement that positive and negative output is rotated, but is difficult to satisfy simultaneously the requirement of car load power character, Economy.
Summary of the invention
From the requirement of car load power character, Economy, vehicle should have driven nature preferably when low speed, during high speed travelling preferably should be arranged.If single planetary pinion is when providing reverse gear, at least two forward gearss can be provided, cooperate the optimization of conical ring stepless speed changes devices with regard to satisfying vehicle substantially driven nature preferably to be arranged when low speed, the requirement of travelling is preferably arranged during high speed, satisfy the requirement that whole speed change gear volume is little, in light weight, the gear ratio coverage area is big simultaneously.
The present invention provides a kind of the have single planetary speed variator of third gear of two forward gearss and a reverse gear and the speed changer of conical ring stepless speed changes devices configuration in upright arrangement.When vehicle when low speed need have preferably driven nature, advance bottom gear and conical ring stepless speed changes devices coupling of the single planetary speed variator of third gear used; When vehicle need have preferably travelling during in high speed, advance top gear and conical ring stepless speed changes devices coupling of the single planetary speed variator of third gear used; When vehicle need be moveed backward, the single planetary speed variator reverse gear of third gear and conical ring stepless speed changes devices coupling were used.
The configuration in upright arrangement of the single planetary speed variator of third gear and conical ring stepless speed changes devices.On demand, the single planetary speed variator of third gear both can be configured in conical ring stepless speed changes devices input shaft end by array, also can be configured in conical ring stepless speed changes devices output axle head by array.
The invention has the beneficial effects as follows the requirement of both satisfying car load power character, Economy, also satisfied the requirement that the speed change gear volume is little, in light weight, the gear ratio coverage area is big.
