Description

Fixed hydraulic suspension

Technical Field

The utility model relates to a special type transportation equipment technique especially relates to a fixed hydraulic pressure hangs.

Background

Because in the large-tonnage field transportation, the automobile body bears the weight, and jolting that the road surface was uneven in the transit caused probably causes the damage to article and vehicle itself, so generally hang automatically regulated automobile body height through setting up hydraulic pressure, make the vehicle obtain more accurate and steady operation, realize turning to the function with the help of the swing arm simultaneously, but turn to the long-term wearing and tearing of in-process swing arm, reduced life.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a fixed hydraulic pressure hangs, through setting up stop gear, has restricted the tilting of swing arm, has improved the whole life that hydraulic pressure hung, realizes raising and lowering functions with the help of hydraulic cylinder, the even running of the vehicle of being convenient for.

In order to achieve the above object, the utility model provides a fixed hydraulic pressure hangs, hang including setting up in the hydraulic pressure of longeron bottom, hydraulic pressure hang including one end rotate set up in the hydraulic cylinder and the non-end position of longeron bottom with hydraulic cylinder's the other end rotates the swing arm of connecting, swing arm one end with the longeron rotates to be connected, the swing arm other end is connected with the wheel assembly through stop gear.

Preferably, the limiting mechanism comprises a limiting support fixed at the bottom end of the wheel assembly and a limiting roller wheel sleeved in the limiting support, the limiting roller wheel is horizontally and rotatably connected with one end of a wheel shaft, and the other end of the wheel shaft penetrates out of the limiting support and then is fixedly connected with the swing arm.

Preferably, the wheel assembly comprises an axle and wheels rotatably arranged at two ends of the axle, and the axle is fixed with the limiting bracket.

Preferably, the swing arm is rotatably connected with the longitudinal beam through a swing arm fixing seat, a cylinder body of the hydraulic oil cylinder is rotatably connected with the longitudinal beam through an oil cylinder fixing seat, and a telescopic rod of the hydraulic oil cylinder is rotatably connected with one end, close to the swing arm fixing seat, of the swing arm.

Therefore, the utility model adopts the above structure fixed hydraulic pressure hangs, through setting up stop gear, has restricted the tilting of swing arm, has improved the whole life that hydraulic pressure hung, realizes raising and lowering functions with the help of hydraulic cylinder, the even running of the vehicle of being convenient for.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Drawings

Fig. 1 is a schematic structural view of a fixed hydraulic suspension according to an embodiment of the present invention.

Wherein: 1. a stringer; 2. an oil cylinder fixing seat; 3. a hydraulic cylinder; 4. a wheel assembly; 5. a limiting bracket; 6. a roller; 7. swinging arms; 8. swing arm fixing base.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.

Fig. 1 is the embodiment of the utility model discloses a structural schematic diagram that fixed hydraulic pressure hung, as shown in fig. 1, the utility model discloses a structure, including setting up in the hydraulic pressure of 1 bottom of longeron hangs, hydraulic pressure hangs including one end rotate set up in hydraulic cylinder 3 of 1 bottom of longeron and non-end position and hydraulic cylinder 3's the other end rotate the swing arm 7 of being connected, 7 one ends of swing arm rotate with longeron 1 and are connected, the 7 other ends of swing arm are connected with wheel assembly 4 through stop gear.

Specifically, the limiting mechanism comprises a limiting support 5 fixed at the bottom end of the wheel assembly 4 and a limiting roller 6 sleeved in the limiting support 5, the limiting roller 6 is horizontally and rotatably connected with one end of the wheel shaft, and the other end of the wheel shaft penetrates out of the limiting support 5 and then is fixedly connected with the swing arm 7. The wheel assembly 4 comprises an axle and wheels rotatably arranged at two ends of the axle, and a limiting bracket 5 is fixed on the axle. Swing arm 7 rotates through swing arm fixing base 8 and is connected with longeron 1, and hydraulic cylinder 3's cylinder body rotates through hydro-cylinder fixing base 2 and longeron 1 to be connected, and hydraulic cylinder 3's telescopic link rotates with the one end that swing arm 7 is close to swing arm fixing base 8 to be connected.

When the lifting device is lifted, a piston rod of the hydraulic oil cylinder 3 stretches, at the moment, one end of the swing arm 7 is limited in the limiting support 5 in the vertical direction through the wheel shaft (namely, the up-and-down swinging motion of the swing arm 7 under the action of the piston rod is limited), so that the hydraulic oil cylinder 3 can achieve the purpose of lifting the longitudinal beam 1, and the whole service life is prolonged by limiting the rotation of the swing arm 7.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
