Description
Technical field
The present invention relates to a kind of mechanically operated forward and reverse stepless speed variator.
Background technique
Although the stepless speed changes devices kind used in mechanical transmission is at present many, due to the deficiency that there is structural inherent defect and transmission power is little, efficiency is low, working life is short etc., its using scope is very limited.Especially in the mechanical transmission of high-power and various complex environment, if communications and transportation is especially in the mechanical transmission of automobile etc., there is no satisfied stepless speed changes devices so far.Though there are many creators to propose kinds of schemes, the too complicated or Shortcomings in practical of its structure, be difficult to carry out, extensive use is seen at end.
The reversing mechanism (i.e. reverse gear) used in mechanical transmission, also also exists the deficiencies such as impact, operation inconvenience or structure are numerous and diverse, needs to be improved further.
Especially compact to simple structure, large power high efficiency energy, stable working be reliable, be convenient to the stepless speed changes devices manipulating, have both negative function, and in mechanical transmission, the special mechanical transmission as complex environments such as automobiles is thirsted for for a long time
Summary of the invention
The present invention be solve present mechanical transmission stepless speed changes devices and reversing mechanism remain deficiency, there is provided that a kind of simple structure is compact, transmission power is large, efficiency is high, stable working is reliable, the life-span is long, using scope is wide, be particularly useful for forward and reverse stepless speed variator of the complex environments such as automobile.
For solving the problems of the technologies described above, forward and reverse stepless speed variator of the present invention is made up of stepless speed variator and reversing device.The coupling shaft of second axle of stepless speed variator with the clutch active part of reversing device and central gear is connected, or the clutch active part of reversing device and central gear are directly connected on the second axle of stepless speed variator.As long as handle the hydraulically operated valve of stepless speed variator and the clutch of reversing device and reverse brake, can carry out forward and reverse by zero-speed to the stepless change high speed.
Stepless speed variator of the present invention is made up of first planet mechanism, driving gear, oil hydraulic motor, hydraulic pipe line, hydraulically operated valve etc.First central gear of first planet mechanism is connected on the first axle, the first row carrier is connected on the second axle, first ring gear is connected with external toothing, external toothing is connected with oil hydraulic motor by driving gear, the hydraulic pipe line of connecting fluid pressure motor is equipped with hydraulically operated valve, by driving gear and external toothing, the rotating speed that opposing torque controls the first ring gear is applied to the first ring gear by oil hydraulic motor, the size of its opposing torque is controlled by hydraulically operated valve, when the opposing torque that oil hydraulic motor applies is zero, first ring gear is unfettered free to rotate, then first planet mechanism loses gearing, if the first axle is that input shaft then becomes idle running, the rotating speed of the second axle is zero, when oil hydraulic motor applies opposing torque, the rotating speed of the first ring gear is reduced, then the rotating speed of the first row carrier and the second axle improves (vice versa), the opposing torque applied when oil hydraulic motor makes the rotating speed of the first ring gear be zero, then the second axle is to run up most.(certainly, as needs, oil hydraulic motor also can make the first ring gear reversion, then make the second axle more to run up.As long as) therefore regulate hydraulically operated valve, the rotating speed of the second axle can be made thereupon to be elevated, thus to realize the second axle by zero to stepless change the most at a high speed.(above-mentionedly only make driving link for the central gear of planetary mechanism, planet carrier makes driven member, also can with other do driving link, as ring gear make driving link, planet carrier makes driven member, so, then correspondingly the brake drum of " external toothing " in figure and high-speed brake (not shown) is connected with central gear.)
Reversing device of the present invention is made up of the second planetary mechanism, clutch and reverse brake etc.Be connected on same axle by the active part of clutch and the second central gear, the secondary part of clutch and the brake drum of reverse brake are connected with the second planet carrier, and the second ring gear is connected on the 3rd axle.When reverse brake loosens, clutch engages, then the second planet carrier be connected with central gear together with rotate, owing to there is no relative movement between the second planetary pinion and the second central gear, that is second central gear, the second planet carrier and the second ring gear lock is integrated, thus the 3rd axle is made to be the running in the same way of 1 with velocity ratio; Work as clutch separation, reverse brake pins the second planet carrier and makes it to maintain static, then the second ring gear and the 3rd axle make antiport with a stable drive ratio.As long as therefore simultaneously controlled clutch and reverse brake, can forward and reverse transmission thereupon.
Because the present invention adopts planetary mechanism, make it structure comparison compact, then because gear-driven transmission power is large, efficiency is high, and hydraulic system manipulation simple and convenient stable working, and be all mature technology, manufacture cost wants relative moderate, thus reaches object of the present invention.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
Accompanying drawing is the schematic diagram of the forward and reverse stepless speed variator of the present invention.
Embodiment
