20 and sealing be cooperatively disposed to support construction 1 between the rack 10 and the cylinder body 20, the support construction 1 includes
Supporting sleeve 2, the supporting sleeve 2 are threadedly coupled with the cylinder body 20.That is, the disclosure is by existing the setting of supporting sleeve 2 of support construction 1
It is threadedly coupled between cylinder body 20 and rack 10 and with cylinder body 20 and realizes assembly, be thus not present as existing middle because split type
Structure and there are problems that gap between adjacent component, connect to pass through supporting sleeve as described above 2 and the screw thread of cylinder body 20
It connects and steering gear can be effectively prevent to generate mechanical abnormal sound due between 1 component of support construction there are gap during the work time
Phenomenon occurs, and which thereby enhances the operating reliability of steering gear.
Optionally, be formed on the portion perimeter face of the supporting sleeve 2 project radially outwardly and with the end of the cylinder body 20
The limit protrusion 21 that portion abuts.While positioning action capable of being played by the limit protrusion 21 to supporting sleeve 2, additionally it is possible to play
Further seal the effect of supporting sleeve 2 and cylinder body 20.Herein optionally, the end of the cylinder body 20 is formed with internal thread, described
The external screw thread 22 being connect with the internal thread is formed on supporting sleeve 2, which is arranged in the close institute of the supporting sleeve 2
On the peripheral surface for stating limit protrusion 21.It carries out that in assembling process limit protrusion 21 can be passed through in supporting sleeve 2 and cylinder body 20 as a result,
It realizes the opposite rigging position of both positioning, and the position by the way that external screw thread 22 to be disposed adjacent to limit protrusion 21, is filling
It is rapidly inserted into the predeterminated position of cylinder body 20 with supporting sleeve 2 in the process so that the limit protrusion 21 on supporting sleeve 2 is close to cylinder body
20 end and then the internal thread by being formed on the external screw thread 22 of supporting sleeve 2 and the end inner peripheral surface of cylinder body 20 into
Row is threadedly coupled and realizes assembly, so as to effectively improve efficiency of assembling.In addition, passing through the screw thread of supporting sleeve 2 and cylinder body 20
The once sealing of connection and both realizations realizes the two of the two by the abutting of the limit protrusion 21 and cylinder body 20 of supporting sleeve 2
Secondary sealing improves the leakage efficiency of supporting sleeve 2 and cylinder body 20 as a result,.But it's not limited to that for the disclosure, the external screw thread 22
The structure of installation position and limit protrusion 21 on supporting sleeve 2 can specifically be arranged according to actual conditions.
Here, in order to improve the sealing performance between supporting sleeve 2 and rack 10, optionally, the first end of the supporting sleeve 2
Inner peripheral surface on be formed with the reducing diameter part 23 of undergauge, the peripheral surface can pass through sealing ring 4 and the rack 10, which seals, to be coordinated.
Optionally, the second end of the supporting sleeve 2 be arranged to be exposed to the end of the cylinder body 20 for it is anti-
Dust hood 40 connects.For example, in the case that the end of the rack 10 is connect with knuckle arm, in order to play dustproof effect, pass through
The junction of rack 10 and knuckle arm be arranged dust cover 40, here, dust cover 40 can be exposed to cylinder as described above
The second end of the supporting sleeve 2 of 20 end of body is connected by modes such as clampings, thus plays the effect convenient for assembly.But the disclosure is simultaneously
It is not limited to this, such as the supporting sleeve 2 can also be arranged as the second end of supporting sleeve 2 and directly be realized with cylinder body 20 and rack 10
Sealing cooperation, at this point, the dust cover 40 can be directly connected to cylinder body 20.
Optionally, the support construction 1 includes oil sealing 3, which abuts with the first end of the supporting sleeve 2, and respectively
It seals and coordinates with the peripheral surface of the rack 10 and the inner peripheral surface of the cylinder body 20.As a result, when steering gear works, oil sealing 3 by
It is expanded to the influence of the high pressure oil in cylinder body 20, so as to effectively seal between rack 10 and cylinder body 20 and oil sealing 3
Gap, effectively avoid occur oil leak phenomena such as.
In order to enable oil sealing 3 has reliable sealing performance, optionally, as depicted in figs. 1 and 2, the oil sealing 3 includes branch
Support bone frame 31 and the rubber seal 32 being connect with the support frame 31, the peripheral surface of the rubber seal 32 and the rack 10
Cooperation is sealed with the inner peripheral surface of the cylinder body 20, the support frame 31 is abutted with the first end of the supporting sleeve 2, the rubber
Sealing element 32 has the sealing lip 33 being interference fitted with the peripheral surface of the cylinder body 20.Here, in order to further increase tooth
The sealing effect of item 10 and oil sealing 3, optionally, the oil sealing 3 further include being arranged on rubber seal glue 32 for compressing institute
State the holddown spring 34 of the cooperation between sealing lip and the peripheral surface of the rack 10.But it's not limited to that for the disclosure, described
Any other structure appropriate may be used in oil sealing 3, as long as reliable sealing performance can be realized.
According to another aspect of the present disclosure, a kind of steering is provided, the steering includes steering system, turns
The steering gear as described above being connect to transmission system and with the steering system and the steer drive, it is described
The both ends of rack 10 are connect with the knuckle arm of the steer drive respectively.
According to the another aspect of the disclosure, a kind of vehicle is provided, which includes steering as described above.
The steering of the disclosure and vehicle by by the setting of supporting sleeve 2 of support construction 1 cylinder body 20 and rack 10 it
Between and be threadedly coupled with cylinder body 20 and realize assembly, thus be not present as it is existing it is middle due to split structure in adjacent component
Between there are problems that gap, to can be effectively prevent by the threaded connection of supporting sleeve 2 as described above and cylinder body 20
The phenomenon that steering gear generates mechanical abnormal sound due between 1 component of support construction there are gap during the work time occurs, and thus carries
