Embodiment
Embodiment
Referring to Fig. 1, it is illustrated that in fluid-link steering machine throttling return oil pipeline be preferred embodiment of the present utility model, specifically
Including throttle joint 1, oil return hose 2 and oil return hard tube 3.Wherein, throttle joint 1 is fixedly connected with turning machine oil-out, oil return
The one end of flexible pipe 2 is docked with throttle joint 1, and the other end docks with oil return hard tube 3, and oil return hard tube 3 is then fixedly attached to steering oil storage
The oil return opening of kettle.
In existing turning machine return line, oil storage kettle by turning machine oil-out and is directly turned to by oil return hard tube 3
Connection, the present embodiment set a throttle joint 1 and oil return hose 2 between oil return hard tube 3 and turning machine oil-out, and regulation turns
To the flow and surge of machine oil return.Wherein as shown in Fig. 2 throttle joint 1 is provided with I end interfaces 101 and II end interfaces
102, throttle joint 1 is fixedly connected by I end interfaces 101 with turning machine oil-out, can pass through nipple or other connections
Joint design.Throttle joint 1 distinguishes position using the joint pipe body 103 with certain length, I end interfaces 101 and II end interfaces 102
In the both ends of joint pipe body 103, the external diameter of joint pipe body 103 matches with the internal diameter of oil return hose 2, and II end interfaces 102 are by connecing
Head tube body 103 is inserted into one end inner chamber of oil return hose 2, and the positioning convex of cone is provided with the end of II end interfaces 102
104, the positioning convex 104 is easy to joint pipe body being oriented in insertion oil return hose, soft joint pipe body 103 is inserted into oil return
Guan Zhonghou, one riveting of suit set 11 is fixed in the end outer wall of oil return hose 2, is being connect the riveting of oil return hose 2 by riveting set 11
On head tube body 103, oil return hose 2 and joint pipe body 103 are fixed, it is now soft by the riveting set 11 and oil return that compress deformation
Positioning convex on pipe 2 and joint pipe body 103 realizes the fixed docking between back leakage connection 1 and oil return hose 2.
Likewise, identical docking mode in Fig. 2 can be used between the other end and oil return hard tube 3 of oil return hose 2, also may be used
Docked using the form of jointing with oil return hard tube 3, oil return hard tube 3 and oil storage kettle connected mode are in existing fluid-link steering machine
Existing connected mode, the present embodiment will not be described here.
In actual applications, throttle joint 1 uses the internal diameter size and II of equal diameter joint, i.e. the I end interfaces of throttle joint
The internal diameter size of end interface is identical.
Throttle joint 1 can also use reducer union, including the I end interfaces internal diameter size of throttle joint to be more than in II end interfaces
The tapered joint of footpath size, I end interfaces internal diameter size can be also used to be less than the expansion nipple of II end interface internal diameter sizes.Specifically
Throttle joint form can be matched according to the requirement of different automobile types.
Oil return hose 2 is not less than 290mm rubber hose, internal diameter root using length according to the installing space of automotive interior
Select to match according to the size of oil return hard tube and throttle joint.
The present embodiment is saved by testing steering surge and turning to abnormal sound eradicating efficacy to set in throttle joint 1
I end interface 101 of joint and the internal diameter size of II end interface 102 and the length of oil return hose 2 of throttle joint are flowed, using section
The combining form of joint 1 and oil return hose 2 is flowed, on the one hand can increase the damping force for turning to return line by throttle joint 1
To maintain to turn to the job stability of liquid in hydraulic pressure turning machine in the oil cylinder of both ends, on the other hand can be delayed by oil return hose 2
Liquid flow impact from red switch to liquid, when fluid-link steering machine is by impulsive force ensure turning machine inner rack do not jump and hit,
And then realize and shake vibration sense caused by steering abnormal sound and steering wheel when elimination vehicle crosses bumpy road.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as employing changing for the various unsubstantialities that methodology and technical scheme of the present utility model are carried out
Enter, or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in the utility model
Protection domain within.
