Abstract

A drag-link joint is composed by a bearing chock, a bearing, a connecting pin, a sealing ring, a choke and a cover plate, wherein, the bearings are respectively provided on the upper and lower bearing chocks which are provided in the open slot at one end of the pull-rod, the bearing choke cooperates with the outer diameter of the bearing; a connecting hole which is corresponding with the inner diameter of the bearing is provided at one end of the joint of the rocker arm; one end of the rocker arm which has the connecting hole connects with one end of the bearing choke which has bearing; the connecting pin corresponds with the connecting hole of the rocker arm, the inner diameter of the upper and lower bearing. In accordance with the shortcomings that the prior drag-link joint is easy to be worn during the movement, the utility model changes the traditional the structure of the drag-link joint, which has the advantages: the installation of bearing makes the operation of the steering mechanism more flexible, and the assembly maintenance are more convenient, which improves the flexible of the drag-link joint, the service life and economic performance greatly. Meanwhile, the vehicle runs steadily; the handle feeling of the driver is stably; the direction is easy to be control; the quantity of the inner components of the joint is small, the structure is compact and the cost is low.

Description

The steering linkages joint

Affiliated technical field

The utility model relates to a kind of motor vehicle steering device, particularly a kind of steering linkages joint.Belong to operation, Department of Transportation according to International Patent Classification (IPC) (IPC); Communications and transportation branch; The big class of trackless terrestrial vehicle; Motor Vehicle, trailer group; The master of steering equipment group; Pull bar is the group technology field.Classification number is B62D17/00.

Background technique

In motor vehicle steering linkages system, generally connect each steering linkages and all use the steering linkages joint.At present, steering linkages joint commonly used, mainly by ball stud, ball-stud socket, the ball stud gland, regulate plug screw, spring, dust ring, oil nozzle, compositions such as cover plate, it is complex structure not only, and there is a certain structure shortcoming, one, because of ball-stud socket and ball stud all adopt rigid material to make, so be contained in the ball stud wearing and tearing easily in movement process between ball-stud socket and the ball stud gland, axial and radial clearance between ball stud and the ball seat is increased, thereby cause whole connector assembly decreased performance, reduce working life greatly, even ball stud occurs and from ball-stud socket, break away from, make the driver can't control deflecting roller accurately, deflecting roller is out of hand and cause the serious consequence of traffic accident.Two, after bulb is loosening, because of this structure can't compensate or the adjusting play automatically, also be difficult to maintenance, whole joint have to be scrapped, Economy is relatively poor.

Summary of the invention

Above-mentioned defective and deficiency at prior art, the purpose of this utility model is to provide a kind of improved steering linkages joint, that this steering linkages joint has is simple in structure, be convenient to assemble, not easy to wear, turn to flexibly, advantages such as long service life, the technical performance that can improve the steering linkages joint effectively and economic performance.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of steering linkages joint, form by bearing support, bearing, connecting pin, seal ring, oil nozzle, cover plate, it is characterized in that: in opening slot of pull bar, on the set upper and lower bearing support bearing is housed respectively, bearing support cooperates with bearing outside diameter is smart, be provided with the attachment hole consistent with bearing bore diameter at rocking arm joint one end; the end that rocking arm has attachment hole is connected by the end that connecting pin and pull bar are provided with bearing, connecting pin cooperates with rocking arm attachment hole and upper and lower bearing bore diameter essence.The step bottom is sealed, and open at the upper bearing bracket top, which is provided with cover plate, and cover plate is fixed on the bearing support with the cover plate retaining screw, cover plate is provided with oil nozzle, so that the injection grease lubrication is equipped with seal ring between upper and lower bearing support and the rocking arm joint, like this when steering operation, pull bar can rotate under the effect of upper and lower bearing flexibly, prevent to make motor vehicle when steering operation thereby reach, cause the out of control phenomenon of deflecting roller because of steering linkages joints wear and loosening.

The beneficial effects of the utility model are: after the utility model adopted said structure, owing to be provided with bearing, it is more flexible that steering equipment is rotated, and it is steady that assurance turns to, and reduces wearing and tearing, thereby be to use the life-span greatly to improve; Simultaneously, vehicle is difficult for play in motion, and the pilot control feel is steady, and direction is grasped easily, and the connector assembly inner body is few, and compact structure is easy to assembly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a part sectioned view of the present utility model.

In the drawings: 1. pull bar, 2. cover plate retaining screw, 3. cover plate, 4. oil nozzle, 5. rocker, 6. connecting pin, 7. seal ring, 8.. bearing, 9. bearing support.

Embodiment

In Fig. 1 and Fig. 2: a kind of steering linkages joint, form by bearing support 9, bearing 8, connecting pin 6, seal ring 7, oil nozzle 4, cover plate 3, it is characterized in that: in 1 one opening Cao of pull bar, on the set upper and lower bearing support 9 bearing 8 is housed respectively, bearing support 9 cooperates with bearing 8 external diameters are smart, be provided with and the consistent attachment hole of bearing 8 internal diameters at Rocker arm 5 joint one end; the end that Rocker arm 5 has attachment hole is connected by the end that connecting pin 6 and pull bar 1 are provided with bearing, connecting pin 6 cooperates with Rocker arm 5 attachment hole and upper and lower bearing 8 internal diameters essence.Step 9 bottoms are sealed, and open at the top of upper bearing bracket 9, which is provided with cover plate 3, cover plate 3 usefulness cover plate retaining screws 2 are fixed on the bearing support 9, cover plate 3 is provided with oil nozzle 4, so that injection grease lubrication, between upper and lower bearing support 9 and the Rocker arm 5 joint seal ring 7 is housed, like this when steering operation, pull bar 1 can rotate under the effect of upper and lower bearing 8 flexibly, prevent to make motor vehicle when steering operation thereby reach, cause the out of control phenomenon of deflecting roller because of steering linkages joints wear and loosening.

The novel rod head that is not only applicable in the tractor with small four wheels steering equipment of this use can also be applicable among the steering equipment of other various wheeled motor vehicles.

Claims

1, a kind of steering linkages joint, form by bearing support, bearing, connecting pin, seal ring, oil nozzle, cover plate, it is characterized in that: in opening slot of pull bar, on the set upper and lower bearing support bearing is housed respectively, bearing support cooperates with bearing outside diameter, be provided with the attachment hole consistent at rocking arm joint one end; the end that rocking arm has attachment hole is connected by the end that connecting pin and rod head are provided with bearing, and connecting pin cooperates with rocking arm attachment hole and upper and lower bearing bore diameter with bearing bore diameter.
