Description
Affiliated technical field
Automotive engineering and intelligent automatic control
Background technique
The overwhelming majority who uses on the automobile is gear-shift transmission at present, and minority is used stepless speed variator.The main structure of existing stepless speed variator is cone pulley and cable wire, by changing the spacing of two relative cone pulleys, the fixing transmission rope of width is in from the position of cone pulley center of circle different distance, thereby obtains the different drive diameter of cable wire.
Though this speed changer has obtained infinite variable speed effect because its driving force a little less than, therefore, be used for the less car of discharge capacity mostly.
Summary of the invention
In order to solve the existing more weak problem of stepless speed variator driving force, the invention provides a kind of automobile with umbrella shape variable diameter continuously variable transmission and intelligent control program, not only can provide bigger driving force, but also can use intelligent control program, make the well coupling of travelling of the power and the automobile of motor car engine.
The technical solution adopted for the present invention to solve the technical problems is: the outer rim of a circular wheel is divided into equal some parts, each outer edge strip can be moved in the direction along center of circle ray, thus the diameter that acquisition can change.By the diameter of change driving wheel and driven wheel, thereby obtain the needed velocity ratio of automobile running.Simultaneously,, set scientific and reasonable control program, realize the high efficiency of transmission and the application of power according to information such as throttle opening, engine temperature and the speed of a motor vehicle.
The invention has the beneficial effects as follows, efficiently solve the shortcoming of present stepless speed variator, and it is simple in structure, firm and durable, rate of fault is low, and is easy to maintenance, cooperates intelligent control program simultaneously, can better adopt power different velocity ratios to be transferred to wheel according to different situations, reach the purpose of efficient energy-saving.

Embodiment
In Fig. 1, initiative driver wheel body (1) along with initiative drive shaft (2), passive drive wheel wheel body (3) along with passive wheel shaft (6) rotates together, umbrella frame seat (7) slides along initiative drive shaft (2) and passive transmission shaft (6), umbrella frame (5) is under the promotion or pulling of umbrella frame seat (7), edge strip slide rail (4) slides outside variable the wheel, change variable position of taking turns outer edge strip, thereby change the diameter of wheel.Driving wheel (1) and driven wheel (3) are by cable wire (8) transmission.
In embodiment illustrated in fig. 2, the variable outer edge strip (9) of taking turns can change its position with respect to the axle center along slide rail, thereby can change its diameter.Left hand view is 3: 1 a state of velocity ratio, and right part of flg is 1: 1 a state of velocity ratio.
In the embodiment shown in fig. 4, driving shaft (2) and driven axle (6) by Bearing Installation on gear box casing (10), umbrella frame (5) is connected with the variable outer edge strip (9) of taking turns by umbrella frame two ends coupling shaft (11) one ends, one end is connected with umbrella frame seat (7), the umbrella frame seat hydraulic actuator (12) that is fixed on the case of transmission (10) is realized promotion and pulling to the umbrella frame seat (7) that rotates with driving shaft (driven axle) by bearing (13), thereby realize the variable control of taking turns outer edge strip (9) by umbrella frame (5), change the diameter of driving wheel and driven wheel, reach infinite variable speed purpose.In order to make the umbrella frame base diameter big as far as possible, so that the umbrella frame bottom can be arranged to such an extent that open, a segment distance is turned to the outer direction of center of circle radiation in variable two ends of taking turns outer edge strip.Speed change master control ram pot (15) two ends are connected with umbrella frame seat hydraulic actuator (12) by hydraulic tubing (14), speed change master control ram pot piston (16) is move left and right under the control of speed change master control ram pot actuating strut (17), thereby when realizing the umbrella frame seat hydraulic actuator (12) on driving wheel, the driven wheel and oppositely control.
Present embodiment has two technical problems: 1, and when vary in diameter, cable wire and variable the wheel between the outer edge strip can form friction.By in rotation, changing wheel diameter, can effectively alleviate.2, when the variable-diameter wheel diameter became big, the spacing between its outer edge strip can increase, and the smoothness between cable wire and the wheel can be affected.Because the distance between the outer edge strip itself is not too big, and cable wire is soft, adds high speed rotating, and therefore, this problem can not influence normal use.
Too big and shortcoming excesssive gap between the outer edge strip that causes can adopt the two-stage speed change in order to solve the vary in diameter amplitude, both two cover speed variator systems to have been combined, the gear ratio amplitude of every cover speed variator system is 1.5: 1-1: 1.
Intelligent control program
This intelligent control program is when certain closure (throttle) aperture, and the speed of different, the positive carry of rotating speed and rev limit amplitude of loading and Oil Switch changes the Intelligent Dynamic control program of speed changer ratio according to the race of engine and when load is arranged.Illustrate below:
When certain throttle and normal water temperature, the idling speed of establishing motor be 2000 (unit for rev/min, down with), the limit speed of positive carry is-10%, be 2000-2000*10%=1800, surpass this limit speed and will stop working or be short of power the motor cisco unity malfunction.The dynamic tachometer value of the action of speed changer positive carry be idling speed-10% to-5%, i.e. 1800-1900.The dynamic tachometer value of action of the negative load of speed changer be idling speed+10% to+20%, i.e. 2200-2400.For example during automobile downhill, will form load, surpass the limit speed of load, motor will greatly weaken the restraining function of the speed of a motor vehicle, even influences traffic safety.
Above numerical value is imaginary percentage and amplitude, and the setting of numerical value can record in the real work of motor on the specific procedure, through optimizing and making overall plans, obtains a suitable numerical value then.
Under this throttle, when engine speed entered the action tachometer value of speed changer, speed changer promptly began to move speed change.Concrete condition, when engine speed was lower than 1800 commentaries on classics, speed changer began action, increased gear ratio, and promptly the speed change master control ram pot actuating strut (17) among Fig. 4 moves right.And when engine speed was higher than 1900 commentaries on classics, speed changer reduced gear ratio, i.e. speed change master control ram pot actuating strut (17) is moved to the left.Under this accelerator open degree, so just can make motor always be in the rotating speed interval of 1800-1900.In this rotating speed interval, the power of motor, moment of torsion and oil consumption have a good state and balance.The driving wheel of automobile is given in power transmission efficiently.
When motor entered load, when rotating speed surpassed 2400, speed changer began action, increased gear ratio, was lower than 2200 until rotating speed.When the intelligent control program of automobile judged that automobile enters negative load operation state, its throttle entered idling mode automatically, keeps the oil consumption of engine rotation minimum, to reach the fuel-economizing purpose.And this moment gas pedal and accelerator open degree signal still effective so that intelligent control program can proper functioning, utilize motor effectively to pin down car speed, its speed changer is ineffective when being unlikely to descending.
When throttle changed, its control program dynamically changed thereupon.So just dynamically change of successive control speed changer ratio always is under the suitable rotating speed interval and good working order, up to the speed change limit that reaches speed changer motor.
When the switching speed of accelerator open degree not simultaneously, the response time of its speed change is also different, to reach the different-effect of quick acceleration and smooth-going acceleration.
