Abstract
The utility model relates to a locking differential mechanism which is used for automobiles. The utility model is composed of a casing body, a planet gear, a shaft, a half shaft gear and a half shaft and is characterized in that the differential mechanism is also composed of a gear shaft, a flying block, a return spring, a locking stopper, a shaft, a middle block and a friction clutch piece; the gear is arranged at the back side of the half shaft at the left side and is engaged with teeth of the gear shaft, the friction clutch pieces are arranged on the gear and the outer side of the gear of the half shaft at the right side, when the automobile occurs the phenomenon that a single side drive wheel slides, a driving device is additionally arranged to drive a static drive wheel which does not slide to rotate, and the automobile runs. The utility model is characterized in that the automobile uses the differential mechanism and has the advantages of strong road adaptability and good passing ability.
Description
The utility model relates to the diff new varieties.
Existing automobile differential is made up of housing, planetary wheel and axle thereof, axle side gear and axle thereof, generally speaking, the rotating speed of the differential left right axle shaft of back-wheel drive, under the situation of normal road surface straight-line travelling, be consistent with the rotating speed of differential casing, but when a certain side drive wheel on the road during monolateral the skidding of the not enough appearance of sliding adhesive ability, this limit semiaxis rotating speed is 2 times of housing rotating speeds, the another side drive wheel does not change, the semiaxis rotating speed then is zero, and automobile can not advance, and road worthiness, crossing ability are poor.
The purpose of this utility model is to provide a kind of automobile locking differential that improves trap for automobile comformability, crossing ability.
The utility model adopts following mode to achieve the goal: with reference to accompanying drawing, this diff is on existing diff basis, set up gear (8) at left side axle side gear (4) back side, set up friction clutch-plate (16 respectively at the gear (8) and axle side gear (5) outside, 17), be positioned on the housing with gear (8) ingear tooth axle (9) on be equipped with and fly piece (10) and pull back spring (11) thereof, be positioned on be equipped with on the latch axle (12) parallel on the housing with tooth axle (9) pull back spring and with fly the latch (13) that piece (10) is fitted, intermediate mass (15) is gone up circle hole sleeve and is contained on the compensating-gear shaft (2), and the aperture is greater than the diameter of axle; When normal operation, left and right sides semiaxis rotating speed is consistent with differential casing, and tooth axle (9) together rotates with housing 1 and gear (8), not rotation of tooth axle (9); But when axle side gear (4) stops operating, axle side gear (5) is during with the twice rotational speed, because differential gear box is rotating all the time, be that tooth axle (9) rotates as periphery relative to gear (8), because gear (8) and axle side gear 5 do not rotate, therefore, tooth axle (9) has rotation only and could together rotate along with diff, when rotational velocity reaches certain value, the centnifugal force that flies piece (10) overcomes spring force and outer opening, top the withstanding on of latch (13) flies on piece (10) V-shaped part, thereby with latch (13) locking takes place, make the tooth axle (9) can not rotation like this, at this moment, differential gear box is still rotating, thereby driven gear (8) rotates by force, because gear (8) is to mesh along circumference waveform tooth pincers formula with axle side gear (4) jointing end face, gear (8) is relative to axle side gear (4) when rotating, make gear (8) and axle side gear (4) that the axial separation motion take place, thereby the friction clutch-plate (16) on the axle side gear (4) is engaged, drive by Friction disk that axle side gear (4) rotates together by housing (1) like this and propelling vehicle advances; When axle side gear (5) stops operating, axle side gear (4) is during with the twice rotational speed, gear (8) drives tooth axle (9) rotation, when rotational velocity reaches certain value, the centnifugal force that flies piece (10) overcomes spring force again and outer opening, top the withstanding on of latch (13) flies on piece (10) V-shaped part, thereby with latch (13) locking takes place, tooth axle (9) again can not rotation like this, cause gear (8) also to stop operating, and axle side gear (4) is still rotating, from and axial separation takes place, promote axle side gear (5) because axle side gear (4) promotes intermediate mass (15), the Friction disk on the axle side gear (5) is engaged, differential casing drives by friction that axle side gear (5) rotates together again and propelling vehicle advances; To the normal turn situation, because left and right sides semiaxis relative rotation speed difference is little, even when turning the corner at full speed, when generation left and right sides semiaxis relative rotation speed is big, but because the speed of a motor vehicle is fast, make the centnifugal force of latch (15) overcome spring force and outwards open, thus make latch (15) forever with fly piece (10) the locking phenomenon can not take place, so just guaranteed normal differential motion.
Characteristics of the present utility model are that automobile adopts this diff, and then its road worthiness is strong, and crossing ability is good.
Below in conjunction with accompanying drawing embodiment is described:
Fig. 1 is that Fig. 2 is in A-A place cross-sectional schematic.
Fig. 2 is that the multistage vertical profile of this diff launches scheme drawing.
With reference to Fig. 1-2, this diff is by housing (1), compensating-gear shaft (2), planetary wheel (3), axle side gear (4,5), semiaxis (6,7), gear (8), tooth axle (9), fly piece (10), pull back spring (11,14), latch axle (12), latch (13), intermediate mass (15) and friction clutch-plate (16,17) form, gear (8) is positioned on axle side gear (4) back side, two gears contact end face closes for breathing out along circumference waveform tooth pincers formula, be positioned on housing (1) and go up tooth axle (9) left part tooth and gear (8) engagement, be equipped with in the middle of the tooth axle (9) and fly piece (10) and pull back spring (11) thereof, be positioned on housing (1) and go up middle latch (13) and the pull back spring (14) thereof of being equipped with of the latch axle (12) parallel with tooth axle (9), the gear (8) and axle side gear (5) outside are equipped with friction clutch-plate (16) and friction clutch-plate (17) respectively, intermediate mass (15) is gone up circle hole sleeve and is contained on the compensating-gear shaft (2), and the aperture is greater than the diameter of axle.
