Description
Technical field
The utility model belongs to new-energy automobile accessory technical field, relates to a kind of planetary automatic shifting transmission adopting hydraulic driving to control.
Background technique
New-energy automobile is as one of country's " seven great strategy new industries ": Executive Meeting of the State Council on September 8 in 2010 considers and adopts " the State Council is about the decision accelerating cultivation and development strategy new industry "." energy-conserving and environment-protective, generation information technology, biology, high-end equipment manufacturing, new energy, new material and new-energy automobile " seven industries are selected, as " accelerating to cultivate and the emerging strategic industries of development based on major technological breakthrough, significant development demand in " decision "." and concentrate strength in major fields, accelerate to advance.The Ministry of Science and Technology issued " electric vehicle development in science and technology " 12 " ad hoc planning " on March 3rd, 2012; the developing goal determined in planning was: by 2015; more than 30, scale Demonstration And Extension is carried out in city; more than 5, the application of novel commercialization pattern pilot is carried out in city; for realizing electric vehicle scale industrialization, pure electric drive automobile sales volume reaches similar vehicle total sales volume about 1%.On June 28th, 2012, the State Council formally issued " energy-conservation with new-energy automobile estate planning (2012-2020) ", the developing goal determined in planning was: by 2015, pure electric automobile and plug-in hybrid-power automobile add up volume of production and marketing and strive for reaching 500,000, to the year two thousand twenty more than 5,000,000.
Because the Present Global energy reduces and the aggravation of environmental pollution day by day, hybrid vehicle and even electric vehicle become the focus that people pay close attention to, and over nearly 5 years, the sale of electric vehicle increases 20.51 ten thousand of 2012 from 2008 1.53 ten thousand.Pure electric automobile is one of universally acknowledged energy-conserving and emission-cutting technology, current development pure electric automobile has become the common recognition of national governments and automobile industry, its research and development have become the focus of automobile industry, and pure electric automobile forms primarily of three parts: power-driven system, energy system and auxiliary system.
Pure electric automobile driving and transmission system, as key components, are subject to the attention of each auto vendor and research institution.Research and development as speed changer very important in transmission system also receive increasing concern, can keep for electric vehicle the study hotspot that the speed changer of high efficiency transmission has become current.The manual gear speed changer (MT) occurred the earliest, the conversion of gear is realized by clutch and manual shift shift fork, this speed changer has that structure is simple, compact appearance, transmission efficiency are high, reliability is high, low cost and other advantages, application is comparatively extensive, but because vehicle is in shift process, necessary cut-off clutch, cause power interruption, have impact on power character and the ride comfort of vehicle, and manual shift result in driving fatigue frequently, causes potential safety hazard.
Transmission for electric automobile should high, the smooth gear shifting of compact structure, transmission efficiency.Make a general survey of the feature of various forms speed changer, do not have one can meet above-mentioned requirements completely.Therefore the planetary automatic shifting transmission that the hydraulic driving that this project intends a kind of power failure-free of exploitation controls, is designed by immanent structure, makes it meet above-mentioned requirements.
Model utility content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of planetary automatic shifting transmission adopting hydraulic driving to control, the feature such as compact structure, transmission efficiency are high, smooth gear shifting that it has.
The utility model solves the technological scheme that its technical problem adopts: a kind of planetary automatic shifting transmission adopting hydraulic driving to control, comprise input shaft, clutch and break, wherein input shaft is connected with gear ring by the clutch friction plate on clutch, gear ring is connected with the brake bush on break by spline again, wherein gear ring is rigidly connected with sun gear again, when clutch pressing, during releasing of brake, control fluid in clutch and enter piston cavity through pipeline, promotion clutch friction plate compresses, transmission of power is to gear ring, in planetary mechanism, gear ring and sun gear are rigidly connected, when clutch unclamps, during break pressing, clutch separation, clutch friction plate is in the state of getting loose, power does not pass to gear ring, control fluid in break enters in piston cavity through pipeline simultaneously, promotes brake strip and compresses, braking gear ring.
Described clutch sleeve is connected on input shaft.
The beneficial effects of the utility model are: realize gearshift by the characteristic of single planet wheel, realize automatic speed changing function in conjunction with clutch and ECU (Electrical Control Unit) simultaneously, clutch size is changed by the sheet number increasing friction plate, to reach loss of weight object, hydraulic drive type clutch and hydraulic drive type break have same characteristic, convenient control, and have identical in conjunction with law of segregation, can focus in the raising of performance, and the impact of aspect difference such as can not to be subject to processing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-input shaft, 2-clutch, 3-break, 4-gear ring, 5-speed changer, 6-clutch friction plate, 7-brake bush, 8-sun gear.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See Fig. 1, a kind of planetary automatic shifting transmission adopting hydraulic driving to control, comprise input shaft 1, clutch 2 and break 3, wherein input shaft 1 is connected with gear ring 4 by the clutch friction plate 6 on clutch 2, clutch 2 is socketed on input shaft 1 simultaneously, gear ring 4 is connected with the brake bush 7 on break 3 by spline again, wherein gear ring 4 is rigidly connected with sun gear 8 again, when clutch 2 pressing, when break 3 unclamps, control fluid in clutch 2 and enter piston cavity through pipeline, promote clutch friction plate 6 to compress, transmission of power is to gear ring 4, in planetary mechanism, gear ring 4 and sun gear 8 are rigidly connected, when clutch 2 unclamps, during break 3 pressing, clutch 2 is separated, clutch friction plate 6 is in the state of getting loose, power does not pass to gear ring 4, control fluid in break 3 enters in piston cavity through pipeline simultaneously, promotes brake strip and compresses, braking gear ring 4.
When clutch 2 unclamp, break 3 pressing time, hydraulic controlled clutch 2 is separated, and clutch friction plate 6 is in the state of getting loose, and power does not pass to gear ring 4; Control fluid in break 3 enters in piston cavity through pipeline simultaneously, promotes brake strip and compresses, braking gear ring 4.Now, the gear ratio of speed changer 5 is relevant to the structure of planetary mechanism, supposes
time, then the reduction speed ratio of speed changer 5 is 3, when rotor axis of electric reverses, realizes reversing gear with coordinating of break 3 by clutch 2.
The utility model characteristic of single planet wheel realizes gearshift, realize automatic speed changing function in conjunction with clutch 2 and ECU (Electrical Control Unit) simultaneously, clutch 2 size is changed by the sheet number increasing friction plate, to reach loss of weight object, hydraulic drive type clutch 2 and hydraulic drive type break 3 have same characteristic, convenient control, and have identical in conjunction with law of segregation, can focus in the raising of performance, and the impact of aspect difference such as can not to be subject to processing.
