Abstract
The invention discloses a connection shaft staggering device for a steering wheel of a car. The connection shaft staggering device comprises a shell, a rotary shaft and a gear fixed to the bottom of the rotary shaft. The interior of the bottom of the shell is connected with the side face of the rotary shaft through a toothed structure. A set of limiting shafts are fixed to the center of the top of the rotary shaft. A hollow structure allowing the limiting shafts to be inserted into is arranged inside the shell. A hollow-out area is arranged on the portion, above the hollow structure, of the interior of the shell. A through hole structure is formed between the hollow-out area and the bottom of the hollow structure and enables the hollow-out area and the hollow structure to communicate with each other. The through hole structure is provided with a set of limiting heads located at the bottom of the hollow structure. A set of pistons are arranged inside the hollow-out area. A set of connection rods are fixed to the centers of the tops of the pistons. The tops of the connection rods are connected with a set of threaded plates. The side faces of the threaded plates are connected with the interior of the shell through thread structures.

Description
Technical field
The present invention relates to automobile mechanical component technology field, specially a kind of connecting shaft dislocation dress for vehicle steering
Put.
Background technology
At present, vehicle steering connecting shaft is in order to prevent from, when clashing into, occurring moving sending out of injury driver's phenomenon on steering wheel
Raw, all dislocation device can be set in vehicle steering connecting shaft, once occur to clash into just can occur misplacing, can be effectively anti-
Only move on steering wheel, and general dislocation device is all the elasticity using helical spring, when it occurs to clash into, the error ratio of appearance
Larger, so this device has certain limitation, further, since helical spring leaks in atmosphere for a long time cruelly, its performance
Can decline, so there is certain danger.
Additionally, also having some common vehicle steering connecting shafts, its body of rod is two parts, and two parts body of rod is in docking section
Dividing is all tangent plane docking, then the one group of helical spring of outside fastening by two parts docking site, and the rigidity using helical spring is prevented
Only inconsistent phenomenon in two groups of bodies of rod, and when collision, because the rigidity of helical spring is not enough, lead to helical spring to support
Open so that two groups of bodies of rod misplace, thus preventing the generation that injury driver's phenomenon is moved on steering wheel, however, this device
Still with itself rigidity of material, and because helical spring leaks in atmosphere for a long time cruelly, its performance also can decline, so
There is certain danger.

Further, described semicircular structure is located at the inside of hollow structure, and described slab construction is located at channel design
Internal.
Further, the end of described connecting rod is fixed on the inside of described thread plate by bearing.
Further, the length sum of the length of described limit shaft and described rotary shaft is spacing more than the bottom arrival of housing
The distance of head.
Further, the center at described thread plate top is provided with hexagonal groove structure.
Further, described helicitic texture includes being arranged on the female thread of enclosure interior and is arranged on the outer of thread plate side
Screw thread, and described female thread is meshed with external screw thread.
Compared with prior art, the invention has the beneficial effects as follows:
1., during normal work, housing is relied on the gravity of itself and by spacing head, the position-limiting action of limit shaft is realized and rotary shaft
Connection, Integral connection structure is simple and reliable；When occurring clashing into, it is more than the air positioned at components interior when the dynamics clashing into triggering
During pressure, the upper end of limit shaft extrudes spacing head and so that it is returned in through-hole structure, makes to occur between housing and rotary shaft
Dislocation, prevents from moving injury driver on steering wheel；
2. due to employ air to spacing head provide pressure, can by adjust thread plate be screwed into depth come control parts inside
Air pressure, can neatly adjust required air pressure according to actual needs, correspondingly disclosure satisfy that different impact forces
There is the requirement of dislocation when spending, applied widely；
3. the compressed media of components interior is air, and cost is very cheap, and air does not have leakage yet and pollutes environment
Hidden danger, safe；
4., because spacing head is movable member, after clashing into and producing dislocation, spacing head is retracted in through-hole structure, spacing head
Significantly damage all without producing with limit shaft itself, only limit shaft need to be pulled out afterwards, you can recover spacing head to limit
The position-limiting action of position axle, therefore can change this device after clashing into generation, have reusable advantage, cost advantage
Significantly.
