Abstract
A fixing device for a differential mechanism comprises a bearing cap, a fastening bolt and an anti-loose lock blade, and is characterized in that a groove is formed in the middle at the top of the bearing cap. By adopting the structure, the lock blade is forced to rotate around the fastening bolt, thereby achieving the purpose of adjusting a nut and preventing looseness.
Description
Technical field
The utility model relates to a kind of diff anchor fitting, particularly at a kind of anti-loosening diff anchor fitting of QT1058 series.Belong to automotive field.
Background technology
Differential gear adjustment-nut is to be used to adjust the main drive disk assembly of back axle---main, ring gear meshes the strength member of trace.The engagement trace of main, ring gear all has very large influence to service life, vehicle bridge operation noise, the load-carrying capacity of main gearbox assembly.Differential gear adjustment-nut is in a single day loosening, will make the engagement trace of active and passive gear slide to tooth top, and the driving torque of driven gear is reduced greatly, causes the active and passive gear heel and toe wear.At present, on the market back axle master, ring gear beat tooth, heel and toe wear phenomenon, except reasons such as user's misoperation, bolt, bearing defective, differential gear adjustment-nut is loosening, the driven gear load-carrying capacity being weakened cause dozen tooth, heel and toe wear, also is a very important reasons.Particularly in overload, under the irregular traffic condition of road conditions, the easier diff nut loosening that causes.
The locking of differential gear adjustment-nut is by on the differential axle pressure cap, with the bolt locking plate of a M8, locking plate is embedded in the adjustment nut retaining hole, reaches the purpose of adjustment nut retaining.This structure is to have quoted former Japan Isuzu Motors technology, and the Isuzu Motors back axle has obtained a large amount of promotion and application at home.But with regard to car opertion condition and service condition, overload at home transportation, road conditions etc. and Japan of such automobile has differently greatly, just makes that also loosening this problem of this differential gear adjustment-nut is more outstanding.
Summary of the invention
At the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of diff anchor fitting, in order to solve the loosening problem of diff.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is that a kind of diff anchor fitting comprises bearing gland, binding bolt and locking locking plate, it is characterized in that: in the bearing gland top middle portion one groove is arranged; Depth of groove is 2mm; Recess width manys 0.1-0.3mm than locking locking plate width.
Main contents of the present utility model increase the constraint to the retaining locking plate exactly, prevent to become flexible.
New construction is the plane of locking plate fixedly, changes to mill a concave plane, and degree of depth 2mm, width are than locking plate width+0.1-0.3mm, and so just being equivalent to has increased a constraint of rotating around bolt of rear end plate to locking plate, thereby reaches the locking purpose of adjustment nut.
Description of drawings
Fig. 1 is former bearing gland structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is the differential gear adjustment-nut structural representation.
The specific embodiment
The locking of former differential gear adjustment-nut is by on differential axle pressure cap 1, with the fixing locking plate 3 of the bolt 2 of a M8, locking plate 3 is embedded in the adjustment nuies 5 retaining holes, reaches the purpose of adjustment nut 5 retainings.The shortcoming of original design is exactly that locking plate 3 and bearing gland 1 are gapped, also are gapped between back stop slot 4 and the locking plate 3 with the fixing locking plate 3 of a bolt 2, so in use, it is loosening that adjustment nut 5 is taken place.New construction is the plane of locking plate 3 fixedly, changes to mill a concave plane, and degree of depth 2mm, width be than locking plate width+0.1-0.3mm, and so just being equivalent to has increased a constraint around bolt of rear end plate 2 rotations to locking plate 3, thereby reaches the locking purpose of adjustment nut 5.
Above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited to above-mentioned giving an example, and those skilled in the art are in essential scope of the present utility model; the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
Claims (3)
