Background technique
In domestic automobile drive axle, adjuster, diff. bearing uses band, and there are two the locking plates of bolt hole to lock, such
Structure also increases material cost firstly, increasing the weight of locking plate；Secondly, locking plate is fixed by bolts to differential bearing lid
On, increase the machining cost of differential bearing lid；In addition, needing to screw in two bolts when assembly, assembly effect is reduced
Rate.To sum up, in existing drive axle, exist due to the locking plate using the fixed adjuster, diff. bearing of two bolts, cause to lock
The problems such as sheet weight increases, and locking plate material cost increases, and the machining cost of differential bearing lid increases, and assembly efficiency reduces
Summary of the invention
The purpose of this utility model is that in view of the above shortcomings of the prior art, provides a kind of differential bearing locking machine
Structure realizes the purpose of drop weight, cost declining, raising efficiency.
The purpose of this utility model is achieved through the following technical solutions:
A kind of differential bearing lockable mechanism, it is characterised in that: be made of adjustment ring 3, locking plate 4 and assembling bolt 5；
Two tapered roller bearings 2 of the differential mechanism are mounted in two semicircle orifices of reducing gearbox 1, two differential mechanisms
The semicircle orifice of bearing cap 6 and two tapered roller bearings 2 cooperate, and connect reducing gearbox 1 and differential bearing with four bolts 7
Lid 6；
The threaded hole that the adjustment ring 3 is constituted with reducing gearbox 1 and differential bearing lid 6 is fixed, and reducer gear reaches
The backlash of standard；The round-meshed one end of the locking plate 4 is mounted in the groove of differential bearing lid 6, circular hole and differential
The circular hole of device bearing cap 6 is aligned, and the other end is mounted in the redistribution grooves of adjustment ring 3；The assembling bolt 5 passes through differential axle
The circular hole for holding lid 6, locking plate 4, the screw hole with differential bearing lid 6.
Further, the locking plate 4 generally C-shaped strip stamping steel plate structure, one end are equipped with for being bolted differential
The circular hole of device bearing cap 6, the other end are equipped with the trapezoidal rack gear for limiting adjustment ring 3.
Further, the differential bearing lid 6 be equipped with for be inserted into the plane groove of limit locking pieces 4, for connecting
The coaxial circular hole and threaded hole of assembling bolt 5, for connecting the semicircle threaded hole of adjustment ring 3 and for connecting bolt 7
Two axisymmetric circular holes.
Compared with prior art, the utility model has the beneficial effects that:
The utility model differential bearing lid uses plane groove structure, for installing locking plate and limitation locking plate rotation, from
And realize and connect locking plate and differential bearing lid with assembling bolt, reduce bolt quantity, reduce the material of locking plate at
This, reduces locking plate weight, improves the assembly efficiency of locking plate.
