Abstract
The utility model discloses a lockable differential mechanism device, the rear of the gearbox is provided with a differential mechanism, the left upper end behind the gearbox is provided with a hydraulic driver and a hydraulic valve, the right side of the hydraulic valve is provided with a piston pushing rod and a fork-lever, the hollow shaft on the left side of the differential mechanism is provided with a locking sleeve, the right end of the locking sleeve is provided with a lock pin, in addition, the gear of the left half shaft and the shell on the left side of the differential mechanism shell are provided with locking grooves and pin holes. When used, the hydraulic valve is tripped, so the piston pushing rod moves forward left and right to drive the fork-lever and the locking sleeve and makes the locking sleeve withdraw or enter the locking grooves, regulating the opening and locking status of the driving of the rear wheels, thus preventing the phenomenon of cannot self rescue because the road is side slipped or the wheels are fallen into the mud from occurring.
Description
The utility model relates to a kind of blocking device of self-propelled vehicle diff, specifically a kind of lockable diff that is used on the small four-wheel tractor change speed gear box.
At present the small four-wheel tractor trailing wheel is because of being the differential drive configuration, in case a rear wheels slip is arranged, another trailing wheel has not just had propulsive effort, and muddy road surface often appears in the rainy day to skid, and trac. heavy burden tractive force inadequately or be absorbed in the phenomenon that marsh be can not extricate oneself.
The purpose of this utility model provides a kind of needs when anti-skidding, the differential of diff can be driven become the lockable diff that constant speed drives.
Scheme of the present utility model is by change speed gear box, diff, lock tube, lock pin, shift fork, hydraulic unit driver and hydraulic valve are formed, its constructional feature is: at the rear portion of change speed gear box the diff shell is housed, differential gear box is peripherally equipped with driven gear, left and right sides axle side gear is equipped with at two ends, the left and right sides in the differential casing, be provided with female splines in the axle side gear of the left and right sides, differential shaft is equipped with at the two ends up and down of diff shell, two differential gears up and down are housed on the differential shaft, two differential gear outer ends respectively are provided with bearing cap shim, the two ends, the left and right sides of diff shell are provided with two hollow shafts, bearing is equipped with in the outside of hollow shaft, two bearings is installed in the inner end of downside left and right sides two-semiaxle sleeve pipe behind the change speed gear box respectively, support by left and right sides axle tube, diff can be rotated, left and right sides semiaxis is housed respectively in the two-semiaxle sleeve pipe, the male splines of two-semiaxle respectively with left half axle gear, the female splines engagement of right axle shaft gear, the hollow shaft in diff left side is provided with lock tube, the lock tube right side is provided with two lock pins, on the housing that is positioned at the differential gear box left side, be provided with two and the corresponding lockhole of lock pin, on the left side of left half axle gear, be provided with two groups four and the corresponding locked groove of lock pin in addition, lock tube is provided with fork slot, shift fork is equipped with in the upper end of lock tube, the lower end of shift fork is installed in the fork slot, the back left upper end of gearbox body is equipped with hydraulic unit driver, and the upper end of actuator is provided with hydraulic valve.
The utility model has the advantages that simple in structure, reasonable in design, easy to install, stable performance, safe and reliable.
Be described further below in conjunction with accompanying drawing:
Accompanying drawing 1 is a TV structure cross-sectional schematic behind the lockable diff.
In the accompanying drawing, diff shell 3 is equipped with at the rear portion of change speed gear box 1, differential gear box is peripherally equipped with driven gear 2, left half axle gear 16 is equipped with at two ends, the left and right sides in the diff shell, right axle shaft gear 7, be provided with female splines in the axle side gear of the left and right sides, differential shaft 12 is equipped with at the two ends up and down of diff shell, two differential gears 8 up and down are housed on the differential shaft, bearing cap shim 24 is equipped with in the outer end of two differential gears, the two ends, the left and right sides of diff shell are provided with two hollow shafts 4, bearing 6 is equipped with in the outside of two hollow shafts, two bearings is installed in the inner end of downside two-semiaxle sleeve pipe 23 behind the change speed gear box respectively, is supported by left and right sides axle tube, and diff can be rotated, left and right sides semiaxis 5 is housed respectively in the two-semiaxle sleeve pipe, the male splines of two-semiaxle respectively with left half axle gear 16, the female splines engagement of right axle shaft gear 7.The hollow shaft in diff left side is provided with lock tube 17, the lock tube right side is provided with two lock pins 18, on the housing that is positioned at the differential left side, be provided with two and the corresponding lockhole 21 of lock pin, on the left side of left half axle gear 16, be provided with two groups 4 and the corresponding locked groove 19 of lock pin in addition.Lock tube 17 is provided with fork slot 20, and shift fork 15 is equipped with in the upper end of lock tube, and the lower end of shift fork is installed in the fork slot 20.The back left upper end of gearbox body is equipped with hydraulic unit driver 11, and the right-hand member of actuator is provided with piston push rod 22, and the upper end of shift fork 15 is installed on the push rod.The upper end of hydraulic unit driver is provided with hydraulic valve 13, and handle 14 is equipped with in the upper end of hydraulic valve, and the lower-left end of hydraulic valve is provided with oil inlet 9, oil return pipe 10.
When little four-wheel cruising, operating handle 14 is moved left, hydraulic valve 13 cuts out oil inlet, fuel-return valve is opened, piston rod 22 and piston are under the effect of hydraulic unit driver pull back spring, automatically move to the left and drive shift fork, lock tube moves to left, this moment, two lock pins were extracted out from the locked groove of left half axle gear, recovered normal differential and rotated.When running into that a tyre slip can not advance or slowly the time, handle can be moved right, open inlet valve and close oil returning tube, piston push rod promotes shift fork to the right under the effect of piston, and the drive lock tube moves right, lock pin is pushed in the locked groove of axle side gear, be about to the left half axle gear locking, differential gear box and left and right sides axle side gear are rotated under the constant speed state, improved work efficiency greatly.
This process is carried out under trailing wheel differential driving condition, because of left half axle gear when the differential, right axle shaft gear, diff shell rotating speed do not wait respectively.When the left half axle gear locked groove wherein one group forward to lock pin on time, be about to the left half axle gear locking.
