Unlimited formula buncher, continuous stepless speed changer, for its method, assembly, subassembly and parts
This application claims the rights and interests of the U.S. Provisional Patent Application No. 61/310,224 submitted on March 3rd, 2010, this application is combined in this by quoting with entire contents.
The field of invention relates generally to speed changer, and more specifically, these creative embodiments relate to buncher (CVT) and unlimited formula buncher (IVT).
The explanation of correlation technique
In some systems, power is characterized with torque and rotating speed.More precisely, in such systems, power is generally defined as the product of torque and rotating speed.Typically, speed changer is connected in power input, and the input of this power provides input torque with input speed.This speed changer is also connected in a load, the output torque of this load request and output speed, and they likely differ from input torque and input speed.Typically, and putting it briefly, a prime mover provides power to input to speed changer, and the power that a slave unit or load-receipt export from speed changer.The premiere feature of speed changer is to be modulated power input, and its mode is that output power is delivered on slave unit the ratio (" speed ratio ") with desired input speed with output speed.
Some thermo-mechanical drives include being known as classification, the discontinuous or fixing multiple speed changer than type.These speed changers are configured to provide the discontinuous or speed ratio of classification in given ratio coverage.Such as, the speed ratio that this type of speed changer can provide is 1:2,1:1 or 2:1, but this type of speed changer is not provided that the speed ratio of centre, such as 1:1.5,1:1.75,1.5:1 or 1.75:1.Other driving means include that one is commonly called the speed changer of buncher (" CVT "), and this speed changer includes a stepless changer.Compared with stepped gearing device, CVT is configured to provide the speed ratio of each mark in given ratio coverage.Such as, in above-mentioned given ratio coverage, CVT usually provides any desired speed ratio between 1:2 and 2:1, this will include such as 1:1.9,1:1.1,1.3:1,1.7:1, etc..Other drivers are also had to use a kind of unlimited formula buncher (" IVT ").Similar with CVT, IVT can produce each speed ratio in given ratio coverage.But, compared with CVT, IVT is configured under stable input speed provide zero output speed (" dynamic zero-speed " state).Therefore, under conditions of speed ratio is defined as input speed and the ratio of output speed, IVT can provide the unlimited set of speed ratio, and therefore IVT is not limited to a given ratio coverage.It should be pointed out that, that some speed changers employ a kind of stepless changer, it is functional that it is connected to produce IVT on other gears and/or clutch in one distribution power arrangement.But, as used herein, term IVT is mainly interpreted as containing a kind of unlimited formula stepless changer, and this converter is functional without being connected to can to produce IVT on extra gear and/or clutch.
Mechanical power transmission field is known polytype stepless or unlimited formula stepless changer.For example it is known that the stepless changer of classification be band-radius variable belt wheel converter.Converter known to other includes liquid static force transform device, ring translator and conical ring converter.In some cases, these converters are connected on other gears to provide IVT functional.Some equation converters can provide unlimited speed ratio changeability in the case of not having additional gear.Some stepless and/or unlimited formula stepless changer is classified as friction-type or towed converter, because they rely on dry friction or elastohydrodynamics traction to transmit torque through converter accordingly.One example of towed converter is ball converter, and plurality of ball element is sandwiched between torque transfer element, and a thin layer elastohydrodynamics fluid is as the torque transmission channel between spheroid and torque transfer element.These creative embodiments disclosed here are mostly concerned with the converter of latter type.
In CVT/IVT industry, among other aspects, for improving efficiency and packaging flexibility, simplify operation, and the improvement reducing the speed changer in terms of cost, size and sophistication and converter also exists a kind of continuous drive.The creative embodiment of the method for CVT and/or IVT disclosed below, system, sub-component, parts etc. has addressed the some or all of aspect of this demand.
These system and methods described herein have several feature, and not having any one single feature in these features is to be responsible for its desired attribute uniquely.It is not intended to limit the scope stated such as following claims, now the feature more highlighted it is discussed briefly.After considering this discussion, and particularly after having read the part of entitled " detailed description of some creative embodiment ", it is understood that these features of system and method are the multiple advantages of the system and method how providing beyond tradition.
