Abstract
The utility model relates to the technical field of automobile speed changing devices, in particular to a hydraulic double-clutch step-less speed changer. Currently, our country does not have any automobile double-clutch step-less speed changer, and most of foreign automobile step-less speed changers adopts a set of plant gear mechanism and a set of drive and driven belt pulley mechanism as power transmission. During work when the reverse shift torque is large, the belt pulleys and a steel belt are easy to skid because of small side pressure, so as to affect the service life of the belt pulleys; in addition, deficiencies, such as complicated structure, complicated manufacturing process, quite high manufacturing cost, etc. exist. The utility model adopts the hydraulic double-clutch step-less speed changer and is a three-axle four-wheel structure; the three axles are respectively axles I, II and III and the four wheels are respectively a reverse shift drive gear, a reverse shift driven gear, a forward shift main belt pulley set and a forward shift driven belt pulley set. A set of gear mechanism and a set of drive and driven gear mechanism are used to directly transmit power. The belt pulleys have long service life, the transmission mechanism is simple and easy to be used and operated.
Description
One, technical field
The utility model relates to the speed change gear technical field of automobile, a kind of specifically hydraulic double clutch buncher.
Two, background technique
It is reported that present China does not still have automobile hydraulic double clutch buncher, the buncher of external automobile adopts a cover capable gear mechanism of star and the driving and driven belt wheel of cover mechanism as power transmission mostly.When the reverse gear high pulling torque is worked, cause belt wheel and steel band to skid easily owing to side pressure is little, influence the working life of belt wheel, and have complex structure, the more high defective of the complicated manufacture cost of manufacturing process.The hydraulic double clutch buncher at home and abroad still is a blank.
Three, summary of the invention
The purpose of this utility model provides a kind of hydraulic double clutch buncher, reaching the minimizing structure, and long service life, simple to operation.
The technical solution of the utility model is: the hydraulic double clutch buncher is three four-wheel-type structures, and three is respectively I axle, II axle, III axle; Four-wheel is respectively reverse driving gear, reverse gear driven gear, forward gears driving pulley group, forward gears driven belt wheels; The I axle is the forward gears input shaft, is solid shaft, and front end stretches in the double clutch bearing hole, and for supporting before the I axle, the front end axle sleeve is equipped with bearing, and the key tooth is connected with forward gear clutch internal key tooth in the double clutch; The middle part is the active drive belt wheel in the driving pulley group, back termination transmission case, and for supporting behind the I axle, the hole provides the oil duct of hydraulic oil for the belt wheel oil cylinder; The II axle is the reverse gear output shaft, is hollow shaft, is sleeved on forward gears I axle driving pulley front portion, and front end key tooth is connected with reverse clutch internal key tooth in the double clutch, transmits the clutch outputting power; The rear end gear is a reverse driving gear; The III axle is a pto, is solid shaft, preceding termination transmission case, and preceding key tooth suit output wheel, back key tooth suit reverse gear driven gear, the centre is a driven pulley, the hole provides the oil duct of hydraulic oil for the driven pulley oil cylinder; The driving pulley group is partly formed by two, and active drive wheel band is an one with the I axle, and the driving pulley pair is sleeved on the I shaft rear end, is connected with oil hydraulic cylinder; The driven belt wheels are partly formed by two, and driven pulley and III axle are one, and the driven belt wheel set is sleeved on III axle front portion and is connected with the driven pulley group oil cylinder; Two groups of spring difference one termination hydraulic jacks, a termination driving pulley pair, driven belt wheel set; Idle wheel is sleeved on the axle of carrier pulley, and the axle of carrier pulley two ends are connected with transmission case; Retarder one end and differential mechanism are by bolt, and the retarder the other end is connected with transmission case with the differential mechanism the other end; Parking spreadet spreadet wheel and differential carrier are fixed together.
Working procedure of the present utility model is:
The forward gears transmission of power: when speed changer forward gears handle placed forward position, hydraulic system was at first connected forward gear clutch asphalt channel in the double clutch, and at this moment reverse clutch does not have working hydraulic pressure and is in separated state.Along with throttle increases, rotating speed improves, and the oil duct valve opening increases, and forward gear clutch hydraulic pressure increases, and clutch engages fully by trackslipping, and the clutch transmission of power is given the I axle.
Its power transmission line is:
At this moment, because reverse clutch is in separated state.Therefore, the reverse gear drive part is freely to change.
The reverse gear transmission of power: when gear change hand lever placed reverse gear position, hydraulic pressure was connected the reverse clutch passage in the double clutch.Forward gear clutch does not have working hydraulic pressure, is in separated state.Along with throttle increases, rotating speed improves, and the oil duct valve opening increases, and clutch hydraulic pressure increases, and clutch engages fully by trackslipping, and the clutch transmission of power is given the II axle.
It transmits circuit:
At this moment, because forward gear clutch is in separated state, therefore, the forward gears drive part is freely to change.
The utility model has the advantages that and adopt the direct transferring power of a set of gears mechanism and a cover main driven gear mechanism, the reverse gear moment of torsion increases, and the belt wheel life-span is long, and driving mechanism is simple, and can require to be improved to series product such as front-wheel drive or rear wheel drive according to difference.Use simple to operately, two gears only move forward and backward.
