Abstract
Limited-slip differential, is made up of the left and right end cap at housing, housing two ends, and the central position at housing two ends is respectively equipped with half axle gear wheel bore and three mutually corresponding cylindrical screw gear holes.In half axle gear wheel bore, left and right half gear is housed respectively, the cylinder part of left and right half gear one end is rotationally connected with the center hole of left and right end cap respectively.Be equipped with 3 in three cylindrical screw gear holes respectively to intermeshing left and right cylindrical screw gear, the other end of left cylindrical screw gear engages with left half axle gear respectively, the other end of right cylindrical screw gear respectively with right axle shaft gears meshing.Simple and reasonable easy enforcement, work timing slip differential is contained in the housing of main reducing gear.The main reducing gear that the utility model limited-slip differential is housed not only can be applied in rear-guard or 4 wheel driven automobile dynamic system, also can be applicable in the power system of other automobile, applied range.There is the advantages such as structure is simple, failure rate is low, limit cunning is reliable for effect.
Description
Technical field
The utility model relates to the component in automobile dynamic system main reducing gear, is a kind of limited-slip differential specifically.
Background technique
Main reducing gear is component assembly important in automobile dynamic system, in main gearbox assembly, all differential mechanism is housed, and its effect is two driving wheel relative ground positive motions when making automobile turning.Fill when travelling on muddy wet and slippery or ice and snow road with the automobile of existing differential mechanism, when a driving wheel and frictional ground force be less than move ahead or backing resistance time, this driving wheel starts to skid.The driving moment of existing differential mechanism operationally two driving wheels is equal, so automobile can not move ahead when driving wheel skids or can not retreat.Find that there is the report that some relate to limited-slip differential, but, these limited-slip differentials in various degree there is the defects such as complex structure, the sliding effect of limit is undesirable, rate of fault is high.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, provides a kind of limited-slip differential that structure is simple, failure rate is low, limit cunning is reliable for effect be applied in rear-guard or 4 wheel driven automobile dynamic system.
The technological scheme realizing the utility model object is: this limited-slip differential, be made up of housing, the left end cap being fixed on housing two ends and right end cap, feature is that the central position at housing two ends is respectively equipped with half axle gear wheel bore and three cylindrical screw gear holes around the mutual correspondence of half axle gear wheel bore; Concentric left half axle gear and right axle shaft gear are housed in half axle gear wheel bore respectively, and the cylinder part of left half axle gear one end is rotationally connected with the center hole of left end cap, and the cylinder part of right axle shaft gear one end is rotationally connected with the center hole of right end cap; 3 are equipped with respectively to intermeshing left cylindrical screw gear and right cylindrical screw gear in three cylindrical screw gear holes of mutual correspondence, the other end of intermeshing left cylindrical screw gear engages with left half axle gear respectively, the other end of intermeshing right cylindrical screw gear respectively with right axle shaft gears meshing.
This limited-slip differential, simple and reasonable, easily implement.Work timing slip differential is contained in the housing of main reducing gear, left end cap and right end cap install bearing respectively, the outer ring of bearing is fixed on the housing of main reducing gear, limited-slip differential housing is equipped with the driven gear of main reducing gear, the driven gear of main reducing gear engages with the driving gear of main reducing gear.
The automobile of the main reducing gear of the utility model limited-slip differential is housed, and when automobile straight line normally travels, left and right vehicle wheel rotational speed is identical, and left and right half gear rotational speed is identical, now the not rotation of cylindrical screw gear.When automobile turning, left and right vehicle wheel rotational speed is different, and left and right half gear rotational speed is not identical yet, and the rotation of cylindrical screw gear, can realize differential.
When automobile travels on muddy or ice and snow road, a driving wheel skids, and the speed discrepancy of two differential gears strengthens, and the speed of cylindrical screw gear rotation increases.Due to the effect of gear helical angle, in the process of transmission, there is certain axial force and produce surface friction drag, at this moment, the friction torque that the driving moment of non-slip driving wheel produces when adding cylindrical screw pinion rotation with regard to the friction moment equaling skidding driving wheel and ground, make the driving moment of two driving wheels different, non-slip drive wheel moment is greater than the driving moment of skidding driving wheel, thus realizes the speed discrepancy of restriction two driving wheels, improves the passing ability of automobile.
The utility model not only can be applied in rear-guard or 4 wheel driven automobile dynamic system, also can be applicable in the power system of other automobile, applied range.There is the advantages such as structure is simple, failure rate is low, limit cunning is reliable for effect, there is practical and popularizing value.

Fig. 2 is the left TV structure schematic diagram of Fig. 1 middle housing part.
In figure: 1 housing, 2 left end caps, 3 left half axle gears, 4 left cylindrical screw gears, 5 right cylindrical screw gears, 6 right axle shaft gears, 7 right end caps, 8 half axle gear wheel bore, 9 left cylindrical screw gear holes, 10 right cylindrical screw gear holes, 11 driven gear attachment holes.
Embodiment
Below in conjunction with accompanying drawing and the embodiment provided, the utility model is further described.
With reference to accompanying drawing, this limited-slip differential, by the driven gear attachment hole 11 on housing 1, housing, the left end cap 2 and the right end cap 7 that are fixed on housing two ends are formed, and are respectively equipped with half axle gear wheel bore 8 and around mutually corresponding three the left cylindrical screw gear holes 9 of half axle gear wheel bore and three right cylindrical screw gear holes 10 in the central position at housing two ends.Concentric left half axle gear 3 and right axle shaft gear 6 are housed in half axle gear wheel bore respectively, and the cylinder part of left half axle gear one end is rotationally connected with the center hole of left end cap, and the cylinder part of right axle shaft gear one end is rotationally connected with the center hole of right end cap.3 are equipped with respectively to intermeshing left cylindrical screw gear 4 and right cylindrical screw gear 5 in three cylindrical screw gear holes of mutual correspondence, the other end of intermeshing left cylindrical screw gear engages with left half axle gear respectively, the other end of intermeshing right cylindrical screw gear respectively with right axle shaft gears meshing.
Claimant presses above-described embodiment, implements this limited-slip differential, and utilizes the driven gear attachment hole on housing to be contained in main reducing gear.The display on probation through inside, the production technology of the utility model limited-slip differential is simple, and cost is low.In rear-guard or 4 wheel driven automobile dynamic system, use and the main reducing gear of the utility model limited-slip differential is housed, when automobile running is on muddy or ice and snow road, the sliding effect of its limit is very reliable, significantly improve the passing ability of automobile, failure rate is low, be subject to the favorable comment of unit on probation.
