Description
Technical field
The utility model belongs to motor turning vehicle bridge technical field, and in particular to a kind of knuckle adjusting nut loss of weight machine
Structure is applied to turn to axle assembly.
Background technique
Domestic automobile turns in vehicle bridge, using locking nut axial restraint hub assembly, one of locking nut structure
Using the gabarit of outer-hexagonal, three uniformly distributed threaded holes are used on end face (see Fig. 1).Such structure is uniformly distributed due to arrangement three
Threaded hole need to occupy biggish radial space, and more using material, weight is big, higher cost.To sum up,
Summary of the invention
The purpose of this utility model is that in view of the deficiency of the prior art, provides a kind of knuckle adjusting nut
Loss of weight mechanism.
The purpose of this utility model is achieved through the following technical solutions:
A kind of knuckle adjusting nut loss of weight mechanism, by 3, three lock washer 1, locking nut 2, knuckle sunk screws
4 and tapered roller bearing 5 constitute；
The threading path of the lock washer 1 and knuckle 3 is fixed, the convex flat face in 1 inner hole of lock washer and knuckle 3
The cooperation of threading path milling flat, end face is bonded with the end face of tapered roller bearing 5；The threading path of the locking nut 2 and knuckle 3
Fixed, three sunk screws 4 are fixed with three threaded holes of locking nut 2 respectively, and the cylinder diameter of axle passes through three of lock washer 1
It is distributed circular hole.
Preferably, in the axial direction of the locking nut 2, half is equipped with round gabarit, and the end face of round gabarit is equipped with three
A uniformly distributed threaded hole for being used to connect sunk screw 4 and lock washer 1, the other half is equipped with the outer-hexagonal knot tightened for spanner
Structure, and the screwed hole of centre for connecting knuckle 3.
Preferably, the lock washer 1 is equipped with 15 uniform circular holes for connecting the cylinder diameter of axle of sunk screw 4,
And the inner hole convex flat face for cooperating the milling flat of knuckle 3.
Preferably, the sunk screw 4 is equipped with the cylinder diameter of axle connecting with lock washer 1, and point with locking nut 2
The external thread structure of cloth threaded hole connection.
Compared with prior art, the utility model has the beneficial effects that:
The utility model knuckle adjusting nut loss of weight mechanism, in the axial direction, half is using round gabarit, separately for locking nut
Half is alleviated weight, is reduced costs using the outer-hexagonal structure reduced；The end of sunk screw using cylindrical structure with
Lock washer connection, improves the reliability that assembling capacity is connected with locking nut.

In figure: 1. lock washer, 2. locking nut, 3. knuckle, 4. sunk screw, 5. tapered roller bearing.
Specific embodiment
The utility model is further elaborated in conjunction with attached drawing.
As shown in Fig. 1 a- Fig. 1 b, outer-hexagonal structure is integrally used in gabarit, since three distribution threaded holes occupy radial sky
Between, the size of outer-hexagonal structure is larger.
As shown in Fig. 2, lock washer 1 is packed into the threading path of knuckle 3, the screw thread in convex flat face and knuckle 3 in inner hole
The cooperation of diameter milling flat, end face is bonded with the end face of tapered roller bearing 5；Locking nut 2 screws in the threading path of knuckle 3 and twists
Tightly；Three sunk screws 4 screw in three threaded holes of locking nut 2 respectively and tighten, and cylinder journal diameter portion passes through lock washer 1
Three distribution circular holes.
As shown in Fig. 3 a- Fig. 3 b, in 3 axial direction of locking nut, half uses round gabarit, uses on the end face of round gabarit
Three uniformly distributed threaded holes, for connecting sunk screw 4 and lock washer 1；In axial direction, the other half is (small using outer-hexagonal structure
In hexagon gabarit shown in FIG. 1), it is tightened for spanner；Using screwed hole of centre structure, for connecting knuckle 3.
As shown in figure 4, lock washer 1 uses 15 uniform circular hole structures, for connecting the cylinder diameter of axle portion of sunk screw 4
Point；Using inner hole convex flat face, for cooperating the milling flat of knuckle 3.
As shown in figure 5, novel sunk screw 4 is connect using cylinder journal diameter portion with lock washer 1；Using external screw thread knot
Structure is connect with the distribution threaded hole of locking nut 2.
