Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
In the disclosure, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, left and right " be usually with
It is defined on the basis of the page of respective drawings, " inside and outside " refers to the inner and outer of corresponding component profile.
As shown in Figures 1 to 4, present disclose provides a kind of steering assembly, the steering assembly include steering rack 1,
Splicing sleeve 2, steering linkage 3 and locking piece, splicing sleeve 2 are adjustably coupled to steering rack 1 along the axial position of steering rack 1
End, one end of steering linkage 3 connect with splicing sleeve 2, and locking piece is used to splicing sleeve 2 being locked in steering rack 1.
When installation, the setting of steering rack 1 is engaged in steering gear housing 7, and with tooth sector (not shown), is turned to
Gear band moves steering rack 1 and moves in the horizontal direction.In general, as shown in figure 3, the right side of splicing sleeve 2 is to steering gear housing 7
Left side the distance between be steering rack 1 single rack stroke L.
The disclosure provide steering assembly in, splicing sleeve 2 along steering rack 1 axial direction, connect to position-adjustable
In the end of steering rack 1, that is to say, that the single rack stroke L of steering rack 1 is adjustable, single rack stroke L change
After change so that the stroke in the horizontal direction of steering linkage 3 also correspondingly changes, thus to the minimum turning radius of vehicle,
The parameters such as steering locking angle have an impact.In this way, during wheel steering system is designed and developed, if you need to the minimum for changing vehicle
When the parameters such as turning radius, steering locking angle, it can be realized by adjusting the stroke of steering rack 1.As shown in Figure 1, at this point, only needing
Distance of the steering rack 1 relative to splicing sleeve 2 is adjusted in the horizontal direction, it is simple to operate, it can be avoided redesign
Steering assembly reduces workload, reduces cost.Moreover, can be guaranteed after being adjusted in place by setting locking piece, turn to
The stroke of rack gear 1 is maintained at certain length.
In the disclosure, realize moved between steering rack 1 and splicing sleeve 2 connection mode can there are many.One
In kind embodiment, the end of steering rack 1 can be threadedly coupled with splicing sleeve 2.It is threadedly coupled so that steering rack 1 and splicing sleeve
2 formation can also realize the accurate adjusting of single rack stroke L while being reliably connected.Wherein, splicing sleeve 2 can be both set in
The outside of steering rack 1 may also set up in the inside of steering rack 1, the disclosure to this with no restriction.
As shown in Figure 1, the end of steering rack 1 has thread spindle 11, splicing sleeve in an embodiment of the present disclosure
2 have threaded hole 21, and thread spindle 11 matches with threaded hole 21, locking piece for be set on thread spindle 11 and with 11 phase of thread spindle
The nut 4 of cooperation.In this way, screwing in the length of threaded hole 21 by adjusting thread spindle 11, the stroke of steering rack 1 is both adjusted,
It is convenient to operate.Moreover, the end of steering rack 1 forms elongated screw thread axle construction, be conducive to the lightweight of steering rack 1.In addition,
By the way that nut 4 is arranged, the axial limiting of splicing sleeve 2 and steering rack 1 can be realized.
It should be noted that in the present embodiment, as shown in Figure 1, the right side that single rack stroke L is nut 4 is arrived
The distance between the left side of steering gear housing 7.At this point, when needing to adjust single rack stroke L, such as need to increase unilateral side
Rack stroke L, firstly, can loosening nut 4；Then turn splicing sleeve 2 is moved to the left its level far from steering rack 1；To
After being adjusted in place, then tightening nut 4, it is connected to its left side on the right side of splicing sleeve 2 with by steering rack 1 and splicing sleeve
2 lockings.In this way, single rack stroke L can be increased.
In other interchangeable embodiments of the disclosure, the end of steering rack 1 can be set on splicing sleeve 2.Tool
Body, splicing sleeve 2 has thread spindle, and the end of steering rack 1 has threaded hole, and thread spindle and corresponding threaded holes close, locking piece
For the nut for being set on thread spindle and being matched with thread spindle.
In addition, turning as shown in Fig. 2, be formed with connecting hole 22 on splicing sleeve 2 in the another embodiment of the disclosure
It is formed with connecting shaft 12 to the end of rack gear 1, splicing sleeve 2 is slidably sleeved in connecting shaft 12 by connecting hole 22.Using
The mode being slidably connected can shorten tune so that position of the connecting shaft 12 in splicing sleeve 2, which is adjusted, becomes more convenient
The time of 1 stroke of steering rack is saved, is promoted and adjusts efficiency.
Further, as shown in Figures 2 and 3, first positioning hole 23, first positioning hole 23 and company are formed on splicing sleeve 2
It connects hole 22 vertically and penetrates through, it is axially spaced on the side of connecting shaft 12 to be provided with multiple second location holes 121.At this point, locking
Part can be positioning pin 5, and the end of positioning pin 5 passes through first positioning hole 23 and is selectively inserted into multiple second location holes 121
One of, when realizing that steering rack 1 has different single rack stroke L, the positive lock of steering rack 1 and splicing sleeve 2.
Wherein, in order to guarantee that the structural strength of steering rack 1 is met the requirements, as shown in Figures 2 and 3, second location hole 121
It can be blind hole.Blind hole structure can reduce the influence of the structural strength to steering rack 1 as far as possible while realizing positive lock,
So that structural strength of the connecting shaft 12 at blind hole is met the requirements.
In addition, as shown in figure 4, being formed with first positioning hole on splicing sleeve 2 in the another embodiment of the disclosure
23, first positioning hole 23 is vertical with connecting hole 22 and penetrates through, and first positioning hole 23 is threaded hole, and locking piece is and first positioning hole
23 positioning bolts 6 matched, positioning bolt 6 pass through first positioning hole 23 to support in the side of connecting shaft 12, realize and turn to
The locking of rack gear 1 and splicing sleeve 2.In this way, further ensuring steering without opening up second location hole 121 in connecting shaft 12
The intensity of rack gear 1, and can be realized the step-less adjustment of single rack stroke L.
In addition, as shown in Figures 1 to 4, connected ball bowl 24 being formed on splicing sleeve 2, being formed in steering linkage 3 and being connected
One end of the bulb 31 that bowl 24 of receiving matches, steering linkage 3 is rotatably connected at splicing sleeve 2 by bulb 31, turns to and draws
The other end of bar 3 can be connected to drive wheel steering with knuckle.
It should be noted that in the disclosure, Fig. 1 to Fig. 4 illustrates only the structural schematic diagram on the left of steering assembly, only
Discuss principle and process that the left side of steering rack 1 when rack stroke needs to adjust is adjusted.It, can be same during practical adjustments
When to being adjusted at left and right sides of steering rack 1, and it is equal to require the left and right sides of steering rack 1 to adjust stroke.Wherein, it turns to
Structure on the right side of device assembly can be identical as the structure in left side, and the principle and process that the right side rack stroke of steering rack 1 is adjusted can
It is identical as its left side rack stroke, it is not just repeating here.
According to the another further aspect of the disclosure, a kind of vehicle is provided, which includes above-mentioned steering assembly.
The preferred embodiment of the disclosure is described in detail in conjunction with attached drawing above, still, the disclosure is not limited to above-mentioned reality
