Abstract
The utility model discloses a kind of automobile half axle gear oil groove, belong to automobile manufacturing field.It is fitted at differential gear and differential gear pad, and to be provided with import large at position, goes out young aerofoil profile tank structure.This structure import is large, and oil-feed is convenient, and go out young, fluid not easily flows out, and can form oil reservoir in the middle of differential gear and differential gear pad, ensures that differential gear and differential gear pad abundance are lubricated.Above-mentioned aerofoil profile tank structure when differential gear rotates, with fluid to throw away track consistent, connect pasta large, oil-feed is convenient, ensures that differential gear lubricates with differential gear pad abundance, raising differential mechanism working stability.And determine that this structure can effectively improve differential mechanism working stability by checking means such as stand test, road test cards.
Description
Technical field
The utility model relates to automotive field, specifically a kind of automobile half axle gear oil groove.
Background technique
Ransaxle is one of important large assembly on automobile, and differential gear is the transmission part of ransaxle key.In car running process, power reaches vehicle bridge input bead through transmission shaft, vehicle bridge input bead drives drive bevel gear to rotate, drive bevel gear drives driven wheel of differential to rotate, the poor shell be now connected with driven wheel of differential rotates simultaneously, the rotating band of difference shell moves the rotation of differential spider, planetary pinion is assemblied on cross axle, the differential gear now engaged with differential pinion gear starts to rotate in the lump, semiaxis and differential gear pass through spline engagement, realize the synchronous axial system of semiaxis and differential gear, because Half axle disc and wheel hub are bolted together, thus drive the rotation of wheel hub, automobile just can travel.Visible differential gear is the important step that automobile power transmits.
As shown in Figure 1, differential gear directly contacts with differential gear pad, easy and differential gear packing friction when differential gear rotates, semiaxis pad worn down makes backlash increase, abrasion powder makes grease be deteriorated, and causes flank of tooth abrasive wear, and gear can be caused time serious to beat tooth.Generally set up oil groove to slow down the problems referred to above at differential gear and differential gear pad position of fitting.But common tank structure is bicircular arcs structure, as shown in Figure 2, though this structure can ensure the normal lubrication of differential gear pad and differential gear, but because it is little to connect pasta, oil groove oil storage is few, gear is when high speed, the work of high-mechanic operating mode, the situation of lack of lubrication may be there is, cause the ablation of differential gear pad or serious wear, backlash increases, and causes differential gear and planetary pinion to beat the differential mechanism faults such as tooth.
Model utility content
In order to solve the problem, the utility model provides a kind of automobile half axle gear oil groove, its object is to solve the differential side gear pad inordinate wear in the process of moving of current partial automobile to such an extent as to differential gear beats the fault of tooth.
A kind of automobile half axle gear oil groove of the utility model, is provided with import greatly at differential gear and differential gear pad position of fitting, goes out young aerofoil profile tank structure.This structure import is large, and oil-feed is convenient, and go out young, fluid not easily flows out, and can form oil reservoir in the middle of differential gear and differential gear pad, ensures that differential gear and differential gear pad abundance are lubricated.
Above-mentioned aerofoil profile tank structure when differential gear rotates, with fluid to throw away track consistent, connect pasta large, oil-feed is convenient, ensures that differential gear lubricates with differential gear pad abundance, raising differential mechanism working stability.And determine that this structure can effectively improve differential mechanism working stability by checking means such as stand test, road test cards.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is differential gear and differential gear gasket construction schematic diagram in prior art;
Fig. 2 is common oil groove structural representation in prior art;
Fig. 3 is the utility model aerofoil profile tank structure schematic diagram;
In figure: 1. differential gear, 2. differential gear pad, 3. common oil groove, 4. aerofoil profile oil groove.
embodiment:
Embodiment 1
As shown in Figure 3, a kind of automobile half axle gear oil groove, the common oil groove 3 at position of differential gear 1 and differential gear pad 2 being fitted changes import into greatly, goes out young aerofoil profile oil groove 4 structure.This structure import is large, and oil-feed is convenient, and go out young, fluid not easily flows out, and can form oil reservoir in the middle of differential gear and differential gear pad, ensures that differential gear 1 lubricates with differential gear pad 2 abundance.
Claims (1)
1. an automobile half axle gear oil groove, is characterized in that, fitting at differential gear and differential gear pad, to be provided with import large at position, and go out young aerofoil profile oil groove, the import of shown aerofoil profile tank structure is large, goes out young.
