Abstract
The utility model discloses a lockable differential mechanism. One sliding rod is arranged on a gearbox; one operating shifting rod is arranged above and on the left of the gearbox; a shifting fork is sheathed on the sliding rod; a lock sleeve is arranged under the shifting fork; a lock pin is arranged on the lock sleeve; in addition, a lock hole and a lock groove are arranged on a shell body of the left of a differential mechanism shell and on the left of a gear of a left half shaft. When the utility model is used, the operating shifting rod can be shifted according to requirements for pushing the shifting fork and the lock sleeve, causing that the lock pin enters or quits; thereby, the separation and the locking of a back wheel driving device is adjusted.
Description
The utility model relates to a kind of locking device of Motor Vehicle differential mechanism, a kind of specifically lockable differential mechanism that is applied on farm tractor or the agricultural transportation vehicle gearbox.
Its back axle of various agri-vehicles of Xiao Shouing is the differential driving structure in the market, as when running into muddy road surface and skidding, vehicle can not be saved oneself.The patent No. that Patent Office of the People's Republic of China is authorized is that 01269428.2 agricultural little four-wheel lockable differential mechanism has overcome this defective.But because the shift fork pushing device of this patent is finished by hydraulic unit driver and hydrovalve, hydraulic structure requires good seal performance, the cost height, and being out of order is difficult for maintenance, is not suitable for using on agri-vehicle very much.
The purpose of this utility model provides a kind of mechanical type can lock differential mechanism, to reduce production costs and to reduce rate of fault.
Scheme of the present utility model is made up of gearbox, differential carrier, driving lever, shift fork, slide bar, lock tube, lock pin and differential gear, its structural feature: slide bar is equipped with at the middle part on gearbox, slide bar can horizontally slip on the housing of gearbox, the left end of slide bar is equipped with shifting block, and the downside of shifting block is provided with locating stud.The upper end of shifting block is provided with groove, and driving lever is housed in the groove.On the gear box casing of shifting block upper end the driving lever support is housed, support is provided with the connection bearing pin, and being installed in of the following middle part activity of driving lever connects on the bearing pin.Shift fork is equipped with in the left side of slide bar, and locating stud is equipped with in the upper end of shift fork, and the lower end of shift fork is installed in the lock tube, and lock tube is sleeved on the axle tube, and semiaxis is housed in the axle tube.The right-hand member of lock tube is equipped with two lock pins, is provided with and the corresponding lockhole of lock pin on the housing that is positioned at the differential carrier left side, and the left end at left half axle halogen wheel is provided with and the corresponding locked groove of lock pin in addition.
When normal vehicle operation, the upper end of driving lever to be pulled to the right, the shifting block pulling slide bar of driving lever lower end is moved to the left, and the drive shift fork is moved to the left, shift fork pulling lock tube moves to left, and two lock pins are extracted out from the locked groove of left half axle gear simultaneously, and the normal differential of vehicle travels.When running into wheel-slip, driving lever is pushed away left, the lower end of driving lever promotes shifting block slide bar is moved right, slide bar drives shift fork, lock tube moves to right lock pin advanced in the locked groove of differential gear differential gear is locked, differential casing and left and right sides differential gear are rotated under the constant speed state, drive wheel and advance.
The utility model has the advantages that simple in structure, easy to operate, safe in utilization, with low cost.
Be described further below in conjunction with accompanying drawing:
Accompanying drawing is a lockable differential design schematic representation.
The middle part of going up of gearbox 1 is provided with slide bar 2 in the accompanying drawing, and slide bar 2 can horizontally slip on gear box casing, and the left end of slide bar is equipped with shifting block 8, and shifting block 8 is fixed on by locating stud 9 on the spindle nose of slide bar, and the upper end of shifting block is provided with groove, and driving lever 6 is housed in the groove.Driving lever support 5 is housed on the housing of shifting block upside, and support is provided with and connects bearing pin 7, and driving lever 6 is to flexibly connect with being connected bearing pin.The left side of slide bar is provided with shift fork 3, and shift fork 3 is fixedly connected on the slide bar by locating stud 4, and the lower end of shift fork is installed in the lock tube.Lock tube 11 is sleeved on the differential mechanism axle tube, semiaxis 13 is housed in the axle tube 10, the right-hand member of lock tube is equipped with two lock pins 12, be provided with two and the corresponding lockhole 14 of lock pin on the housing that is positioned at the differential carrier left side, the left end at left half axle gear 16 is provided with and the corresponding locked groove 15 of lock pin in addition.
