Description
Technical field
The utility model relates to automobile speed-changing device, particularly a kind of mixed stepless speed-changing device.
Background technique
In nearest decades, Variable Speed Technology (CVT) has been made significant headway, and has obtained and has developed comparatively widely and apply.Stepless speed variator is compared with traditional gear-box speed changer, saved complicated gear train transmission device, adopt the variable driving and driven belt wheel of the working diameter transferring power that matches, realized the continuous variation of velocity ratio, thereby make engine operating condition and transmission system obtain optimum Match, improve fuel economy and the power character of car load, reduced exhaust emission.Stepless speed variator simple in structure, reduced product cost, reduced to take up room, and improved riding comfort.
Existing stepless speed variator, mainly comprise the basic elements of character such as driving pulley, driven pulley, V-type driving belt and oil hydraulic pump.Driving pulley and driven pulley all are comprised of movable plate and fixed tray, and movable plate and fixed tray are all cone structures, and their conical surface forms the V-type groove and combines with the V-type driving belt.At first the power of engine output shaft output be delivered to the driving pulley of stepless speed variator, then by the V-type driving belt, is delivered to driven pulley, passes to wheel finally by retarder, differential mechanism and drive automobile.Move axially to change by driving pulley and the movable plate of driven pulley the radius of clean-up that driving pulley, the driven pulley conical surface are combined with the V-type driving belt during work, thereby change velocity ratio.The axial internal clearance of movable plate is that the cylinder pressure that need to regulate driving pulley, driven pulley according to the driver by the speed change gear control system is realized.
In the hydraulic system of stepless speed variator, the effect of driven pulley oil hydraulic cylinder is to control driven pulley to be applied to the clamping force on the V-type driving belt, prevents from occurring skidding between driven pulley and V-type band, to guarantee dynamic high efficiency, the transmission reliably from motor.The driving pulley oil hydraulic cylinder is controlled the position of driving pulley movable plate and is moved vertically, and the V-type driving belt of driving pulley moves along the V-type groove, and because the total length of driving belt is constant, the V-type driving belt on driven pulley moves in the opposite direction along the V-type groove.Continuous variation occurs in the turning radius of V-type driving belt on driving pulley and driven pulley, thereby realizes the continuous variation of speed ratio.
Under the high speed steady working condition, higher moment of torsion and the power of output that motor is lasting, need between V-type driving belt and driving and driven belt wheel to maintain for a long time larger frictional force, prevents between V-type driving belt and belt wheel occurring the phenomenon of skidding.And coming from driven pulley, frictional force is applied to the clamping force on the V-type driving belt.In this process, in order to maintain the clamping force that driving belt is larger, the driven pulley oil hydraulic cylinder need to keep higher oil pressure, the work capacity of driven pulley oil hydraulic cylinder derives from the oil pump by driven by engine, thereby increased the energy consumption of motor, so existing stepless speed variator is compared the automatic transmission of other types, had the higher defect of oil consumption under the high speed steady working condition.
