Abstract

The utility model discloses an assembly structure for a hinge connector and a hinge bolt of an automobile steering oil pipe. The assembly structure comprises the hinge connector and the hinge bolt. The hinge connector comprises a connector portion and a bolt body portion, a fluid cavity is formed inside the connector portion of the hinge connector, the bolt body portion of the hinge connector is a pipe, the fluid cavity is communicated into the pipe, the hinge bolt penetrates through the connector portion to be connected to a connecting body, a bolt body of the hinge bolt is internally provided with a flow channel, and the flow channel is communicated with the fluid cavity through a through hole in the wall of the bolt body. The assembly structure for the hinge connector and the hinge bolt of the automobile steering oil pipe has the advantages that fluid can be filled with transition points in a moving oil suction pipe, so that fluid flowing efficiency is improved; the hinge connector is used in cooperation with the hinge bolt, so that the fluid flows smoothly.

Description

A kind of articulated joint of automotive steering oil pipe and the assembly structure of hinge bolt
Technical field
The utility model relates to automobile steering system field, particularly a kind of articulated joint of automotive steering oil pipe and the assembly structure of hinge bolt.
Background technique
In fluidic circuit, need to pass through a lot of inflexion points, these positions just need hinge bolt and articulated joint to be used in conjunction with.Particularly, in heavy truck field, in oil hydraulic circuit, just need articulated joint to coordinate and turn to fuel sucking pipe will turn to liquid to be transported to steering box and steering pump from oil can.But the articulated form of existing articulated joint exists fluid can not fill the problem of hinge bolt completely, reduce the utilization efficiency that turns to liquid.
Model utility content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of and can make fluid in motion fuel sucking pipe, be full of transition point, makes fluid the flow articulated joint of automotive steering oil pipe smoothly and the assembly structure of hinge bolt.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of articulated joint of automotive steering oil pipe and the assembly structure of hinge bolt, comprise articulated joint, hinge bolt, described articulated joint comprises connector portions, key portion, in the connector portions of described articulated joint, be provided with fluid chamber, the key portion of described articulated joint is body, in its pipe, be communicated with described fluid chamber, described hinge bolt is connected on connecting body through described connector portions, is provided with by the runner in the through hole communication of fluid chamber on its key wall in the key of described hinge bolt.
In described connector portions, be arranged with the pilot hole that the hinge bolt that is communicated with described in two inside and outside confessions of connector portions passes.
In the pipe of the key portion of described articulated joint, one end is communicated with described fluid chamber, and the other end is communicated with fuel sucking pipe.
Between described connector portions and connecting body, be provided with the gasket seal being socketed in outside hinge bolt key, between the nut of described hinge bolt and connector portions, be also provided with the gasket seal being socketed in outside hinge bolt key.
Described connecting body is steering box hydraulic fluid port or steering pump hydraulic fluid port.
The utility model adopts said structure, has the following advantages: 1, can make fluid be full of transition point in motion fuel sucking pipe, increase the efficiency of fluid; 2, coordinate with hinge bolt, fluid is flowed smooth and easy.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is external structure schematic diagram of the present utility model;
Fig. 3 is the cross section structure figure of articulated joint in the utility model;
Fig. 4 is the external structure of articulated joint in the utility model;
In Fig. 1~Fig. 4,1, connector portions; 2, key portion; 3, fluid chamber; 4, runner; 5, hinge bolt; 6, connecting body; 7, through hole; 8, pilot hole; 9, fuel sucking pipe; 10, gasket seal.
Embodiment
A kind of articulated joint of automotive steering oil pipe and the assembly structure of hinge bolt as shown in Figure 1 to 4, comprise articulated joint, hinge bolt 5, articulated joint comprises connector portions 1, key portion 2, in the connector portions 1 of articulated joint, be provided with fluid chamber 3, the key portion 2 of articulated joint is body, in its pipe, be communicated with described fluid chamber 3, hinge bolt 5 is connected on connecting body 6 through described connector portions 1, is provided with by the runner 4 in the through hole 7 communication of fluid chambeies 3 on its key wall in the key of hinge bolt 5.
In connector portions 1, be arranged with and be communicated with two inside and outside pilot holes 8 that pass for hinge bolt of connector portions 1.Pilot hole port diameter matches with the external diameter of hinge bolt, and pilot hole, in two parallel planes, is for hinge bolt 5 can therefrom be passed.The angle of pilot hole and end face is 90 °, because hinge bolt 5 is cylindrical.In the pipe of the key portion 2 of articulated joint, one end is communicated with fluid chamber 3, and the other end is communicated with fuel sucking pipe 9, makes fluid flow to fittings body from fuel sucking pipe 9 and flow to hinge bolt place again, then flow to next joint.Between connector portions 1 and connecting body 6, be provided with the gasket seal 10 being socketed in outside hinge bolt 5 keys, between the nut of hinge bolt 5 and connector portions 1, be also provided with the gasket seal 10 being socketed in outside hinge bolt 5 keys, in order to prevent that fluid from leaking from here, fluid chamber 3 diameters are greater than the diameter of inner pipe of the key portion of articulated joint, this structure is to penetrate after fluid chamber 3 at hinge bolt 5 in order to make, fluid can surround hinge bolt, which make regardless of the through hole on hinge bolt in direction, fluid can flow in hinge bolt from fluid chamber 3, increases fluid and flows smooth and easy.Described connecting body 6 is steering box hydraulic fluid port or steering pump hydraulic fluid port.Connecting body 6 can be the hydraulic fluid port of steering box, can be also the hydraulic fluid port of steering pump, and hinge bolt all can be used in the hydraulic fluid port joint of these two parts.
Urgent hinge bolt 5, the inner tube that now cannot ensure the through hole 7 of hinge bolt and the key portion of articulated joint is relative, because the diameter of fluid chamber 3 is greater than the external diameter of hinge bolt 5, can ensure that whole hinge bolt outside is all full of fluid, ensure that fluid flow into the through hole of hinge bolt from the inner tube of the key portion of articulated joint smoothly, and flow into runner 4.Oil flow in the hydraulic fluid port of connecting body (steering box or steering pump) from the runner in hinge bolt.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted the technical solution of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
