Fig. 3 is the section drawing of the structure of wheel hub in the knuckle assembly in the presentation graphs 2.
The specific embodiment
Below with reference to accompanying drawing the specific embodiment of the present utility model is described in detail.
As shown in Figures 2 and 3, the hub 13 that the utility model provides comprises wheel hub 21, and this wheel hub 21 comprises: connecting portion 23 is used for captiveing joint with wheel; Bearing installation portion 22 is used for captiveing joint with bearing cone; And fastening part 18, be used to install fastener; Wherein, described wheel hub 21 also comprises the stage portion 19 that is used to install the parts that extract the wheel hub rotary state, and this stage portion 19 is between described bearing installation portion 22 and fastening part 18, and the diameter of described fastening part 18 is less than the diameter of described stage portion 19.
In hub 13 provided by the utility model, the wheel hub 21 of this hub 13 also comprises stage portion 19, and this stage portion 19 is used to install the parts that extract the wheel hub rotary state, as is sleeved on the round body on the stage portion 19 of this wheel hub 21.Because wheel hub 21 rotates synchronously with wheel, thereby the round body that is installed on the stage portion 19 of wheel hub 21 also has the state of kinematic motion identical with wheel.
Stage portion 19 is between bearing installation portion 22 and fastening part 18, and the diameter of described fastening part 18 is firmly installed with the parts that can utilize fastener will extract the wheel hub rotary state less than the diameter of described stage portion 19.
According to hub 13 provided by the utility model, because the wheel hub 21 of this hub 13 is provided with the stage portion 19 that is used to install the parts that extract the wheel hub rotary state, thereby this parts are installed, to obtain the state that wheel hub rotates by the sensor that cooperates with these parts.
Further preferably, the diameter of stage portion 19 is less than the diameter of described bearing installation portion 22, thereby the parts that are installed in stage portion 19 can also play positioning action to the bearing that is installed in bearing installation portion 22.
The utility model also provides a kind of knuckle assembly, as shown in Figure 2, this knuckle assembly comprises steering swivel 10, bearing 12, above-mentioned hub 13 provided by the utility model, gear ring 15 and clamp nut 16, described steering swivel 10 is captiveed joint with the outer ring of bearing 12, the inner ring of described bearing 12 is fixedly mounted in the bearing installation portion 22 of described wheel hub 21, gear ring 15 is installed on the stage portion 19 of described wheel hub 21, and described clamp nut 16 is threaded on the fastening part 18 of described wheel hub 21.
As mentioned above, owing in wheel hub 21 provided by the utility model, be provided with stage portion 19, thereby gear ring 15 can be installed on this stage portion 19, these gear ring 15 effects are to extract the rotary state of wheel hub 21, and then extract the rotary state of wheel.Certainly, being not limited to gear ring 15 as the parts that extract wheel hub 21 rotary states, also can be the various parts that cooperate with sensor be convenient to, as long as can be convenient to the rotary state that sensor arrives wheel hub 21.Sensor can be various tachogens, is installed in the position of contiguous gear ring 15 on the steering swivel 10 usually.
