Abstract
The invention discloses a kind of gear type stepless speed changer of efficient high-speed, efficient is near 100%, and speed change is soft, reliable operation, easy to manufacture, can also play the effect of neutral simultaneously, also can move backward, be particularly suitable for the usefulness of Motor Vehicle speed change, to replace existing multispeed manual transmission etc.Pressurized air, electric energy or engine cooling water etc. can also be provided in the time of speed change.
Description
The present invention is efficiently a kind of, the stepless speed variator that the traffic tool such as automobile train tractor tank are suitable for, and combined efficiency is near 100%.
Existing stepless speed variator adopts the friction type usually, with wooden unit, belt, taper cone pulley, grinding disk etc., reach infinite variable speed purpose, can not high speed operation, efficient is low again, therefore the traffic tool such as automobile can not use stepless speed variator and use multispeed manual transmission up to now, make troubles to driving.
Purpose of the present invention will be invented a kind of stepless speed variator exactly, and it can high speed operation, does not lose efficient again.
The object of the present invention is achieved like this, train around utilizing, and when driving wheel was transferred to driven wheel by the planet wheel on the tie-rod, according to load variations and artificial control, tie-rod and driven wheel can change or not change, and perhaps the two all changes.In the process that we brake tie-rod, the rotating speed of driven wheel (output wheel) just changes continuously.To the braking of tie-rod if use the friction method, then give birth to heat and wasted power, and it is unreliable to work, if allow the gear teeth on the tie-rod periphery drive a kind of power absorption conversion equipment, (as gas compressor, water pump, generator or the like) and by valve or rheostat control this energy conversion device, then the tie-rod resisting moment of rotating just changes continuously, up to change motionless become fixed shaft gear train till, in this process, we have just realized stepless change, and energy is not wasted.
Below in conjunction with accompanying drawing invention is further described.
1 is driving wheel (sun gear) in the accompanying drawing, the 2nd, and planet wheel, the 3rd, tie-rod (on the outer garden gear teeth being arranged), the 4th, driven wheel, the 5th, reverse-gear, the 6th, output flange, the 7th, reverser handle, the 8th, speed change lever, the 9th, the power absorption conversion equipment, as gas compressor, generator, water pump etc.We suppose that 9 is generators, realize that infinite variable speed principle is as follows: when the handgrip when 8 was in releasing orientation, driving wheel 1 drove planet wheel 2 around driven wheel 4 rotations, and tie-rod 3 also rotates (on 4 load being arranged), drives generator work simultaneously.When the handgrip that promotes 8, in the process that pushes away, resistance is increasing up to infinite, and the tie-rod resisting moment increased and was braked this moment, and the gearwheel band on the tie-rod is motionless 9, so tie-rod is fixed, has become fixed shaft gear train, transmission 4 outputs, this moment 5 freedom.In this process, speed ratio can change to 1 from 1000.Decide according to design parameter.Because any rotation of tie-rod is all absorbed by 9, so energy is not wasted.The efficient of reality middle gear system and 9 efficient are all very high, have determined that combined efficiency is very high, and obviously, rotating speed is higher also can be born.And 8 when being in releasing orientation, promptly plays neutral, and speed change is very soft, when needing reversing pulling 7,6 forward with 5 engagements, 4 freedom are so can move backward.
By above narration, as seen our purpose reaches.
Claims (3)
