Description
Technical field
The utility model relates to a kind of speed change gear, especially relates to the automobile-used nothing retaining of the pure gear type of using on a kind of automobile speed change gear.
Background technique
At present, in automobile industry, " Variable Speed Technology " is one of key technology of restriction development of automobile.From the enforcement period of the ninth five-year plan, the research and development of car CVT (continuously variable transmission) has been put into the tackle key problems in science and technology plan of country.Automotive industry has many stepless speed variators such as automobile-used AT, CVT, IVT, disc type now and exists a lot of not enough: complex structure, with the friction driving is essence, fails to solve well the contradiction between drive plate clamping force, metal chain stiction, intermediate gearing energy consumption and the transmission efficiency.1, friction driving CVT: the friction driving principle is very simple, realizes that stepless change is also more convenient.Main structure has: V-type rubber belt type, metal band type, multi-disc type, steel ball type, roller rotation plate type etc.Feature is that frictionally is realized transmission of power.Friction driving CVT realizes that high-power, high efficiency stepless change transmission is extremely difficult.2, hydraudynamic drive: main structure has liquid_viscosity regulator, fluid power to become to turn round, oil motor etc.Feature is to be the media implementation transmission of power with liquid.And torque converter is high to requirement on machining accuracy, and the manufacturing process complexity has increased cost.Transmission efficiency is low, and the oil consumption height is the unsurmountable shortcoming of hydraulic automatic gearbox.This automatic transmission case (AT) mainly utilizes torque converter to cooperate the differential gear train gear-box to realize the gearshift function.3, electromagnetism transmission: main structure has frequency control of motor speed, DC motor speed-regulating, speed-adjustable motor etc.The application of this mode is commonplace.Its advantage is to use conveniently, and its shortcoming is that efficient is too low, and system is too complicated, and cost is also higher.4, electric control automatic gear shifting case: it is the same with (AT) that the electric control automatic gear shifting case is called for short " AMT ", is not infinitely variable transmission, is the stepped transmission case of controlling automatically.Difficult point in its design is that automatically the parameter of control is too many, the most difficult is clutch " from close " control (so-called half from hanging) of pilot process.Though many in the world countries have dropped into the research and development to electric control automatic gear shifting case (AMT), do not see the report of batch process always, it serves to show the difficult of its progress.5, present unique realization is infinite variable speed is exactly metal tape/chain stepless speed variator, and it is representing the high technology level of our times; But still fail really to break through the fatal obstacle of traditional stepless speed variator, performance is low, cost is high, efficient is low, the life-span is short; Additional-energy consume is high, and mechanism is complicated, and fault is many, and weight, volume is big, maintenance cost is big.
In sum: metal belt type stepless variable case (VDT-CVT) and roller rotation plate type infinitely variable transmission (Extroid CVT) etc. is inefficient Friction Stepless and complex structure.It all is very difficult further improving transmission efficiency and transmission power.
