Abstract
The utility model discloses a rotary cylinder body for a steering wheel. The rotary cylinder body for the steering wheel is characterized in that a plane (3) parallel to an axis of the cylinder body is arranged on the lateral wall of the cylinder body; a mounting hole (6) and an air flue hole (4) communicated with a piston cavity (2) are formed in the plane (3); the cylinder body is formed by die-casting; and a cavity (5) formed by die-casting is formed on the plane (3) and the cavity (5) is arranged at the unoccupied position of the plane (3) in a manner of keeping away from the mounting hole (6) and the air flue hole (4). Compared with the cylinder body formed by casting, the entire cylinder body has the advantages of more compact internal material, higher strength, better sealing property and no air leakage or blow-by phenomenon; the cavity is formed on the plane provided with the air flue hole in a die-casting manner, so that the strength of the cylinder body is further improved; and meanwhile, the material is saved, the product weight is reduced, and the manufacturing cost is correspondingly reduced, so that the cylinder body is more reasonable in layout.
Description
Technical field
The utility model relates to automobile technical field, is specifically related to a kind of steering wheel and rotates cylinder body.
Background technique
Figure 1 shows that traditional steering wheel rotates cylinder body, be provided with piston rod via hole and piston cavity in cylinder body, piston rod drives piston to-and-fro motion in piston cavity, except piston is housed, hydraulic oil is housed also in the piston cavity.The coaxial setting of piston rod via hole and piston cavity and being interconnected.Cylinder side wall is provided with the plane 3 with the Boring mill line parallel, and 4, one air flue holes, two air flue holes 4 that plane 3 is provided with four mounting holes 6, communicate with piston cavity are the intake duct hole, and another air flue hole 4 is gas-discharging channel hole.
The subject matter that exists is: (1) whole cylinder body adopts cast molding, causes the cylinder interior material loose, gas leakage easily, cylinder body poor sealing, gas blowby easily; (2) the cylinder body localized design is unreasonable, and raw materials consumption is more.
The model utility content
The utility model improves at the problems referred to above, aims to provide that a kind of inner materials is tight, intensity is high, steering wheel in light weight, good sealing effect rotates cylinder body.
For this reason, the technological scheme that the utility model adopts is: a kind of steering wheel rotates cylinder body, in cylinder body, be provided with piston rod via hole and piston cavity, described piston rod via hole and the coaxial setting of piston cavity and be interconnected, cylinder side wall is provided with the plane with the Boring mill line parallel, the air flue hole that described plane is provided with mounting hole, communicates with piston cavity, key is: described cylinder body adopts casting forming, described plane is provided with the cavity of casting forming, and described cavity is avoided the vacant position that mounting hole and air flue hole are arranged on the plane.
As preferably, described plane is provided with four mounting holes and two air flue holes, four rectangular distributions of mounting hole, and two air flue holes are arranged between four mounting holes.
Totally three of described cavitys, one of them cavity is positioned at the left side of four mounting holes, and another cavity is positioned at the right side of four mounting holes, also has a cavity to be dumbbell shaped, be arranged between four mounting holes, two air flue holes lay respectively at the left and right waist outside of dumbbell shaped cavity.
Beneficial effect:
(1) whole cylinder body adopts die cast, compares the cylinder body of cast molding, and inner materials is tightr, and higher, the better tightness of intensity can not leak air or gas-blowing phenomenon longer service life;
(2) die casting cavity on the plane that the air flue hole is set has further increased cylinder strength, has saved material simultaneously, has reduced product weight, compares the used raw material of conventional construction still less, and intensity is higher.

Fig. 2 is the structural representation that the steering wheel after improving rotates cylinder body.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is the right elevation of Fig. 2.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the utility model is described in further detail:
In conjunction with Fig. 2---steering wheel shown in Figure 4 rotates cylinder body, is provided with piston rod via hole 1 and piston cavity 2 in cylinder body, and piston rod drives piston to-and-fro motion in piston cavity 2, except piston is housed, hydraulic oil is housed also in the piston cavity 2.Piston rod via hole 1 and piston cavity 2 coaxial settings and be interconnected.Cylinder side wall is provided with the plane 3 with the Boring mill line parallel, the air flue hole 4 that plane 3 is provided with mounting hole 6, communicates with piston cavity 2, and the above is identical with traditional steering wheel rotating cylinder body structure, does not repeat them here.
Difference is: cylinder body adopts casting forming, and plane 3 is provided with the cavity 5 of casting forming, and cavity 5 is avoided the vacant position that mounting hole 6 and air flue hole 4 are arranged on plane 3.
Preferably, plane 3 is provided with four mounting holes 6 and 2, four mounting holes, the 6 rectangular distributions of two air flue holes, and two air flue holes 2 are arranged between four mounting holes 6.The quantity in mounting hole 6 and air flue hole 2 is not limit, and arranges as required, also is provided with the air flue plug hole 7 that communicates with one of them air flue hole 2 on plane 3, and the auxiliary hole of air flue plug hole 7 for forming in the processing air flue hole 2 need seal by plug.
Be preferably, totally three of cavitys 5, one of them cavity 5 is positioned at the left side of four mounting holes 6, another cavity is positioned at the right side of four mounting holes 6, also have a cavity 5 to be dumbbell shaped, be arranged between four mounting holes 6, two air flue holes 2 lay respectively at the left and right waist outside of dumbbell shaped cavity 5.
