Abstract
The utility model relates to a turning transitional rocker arm, which comprises a rocker arm base, a rocker arm shaft welded to the interior of the rocker arm base and a middle rocker arm connected to the lower part of the rocker arm base, wherein two conical roller bearings are mounted on the rocker arm shaft; sealing rings and retaining rings are arranged at the end parts of the outer sides of the conical roller bearings; and the middle rocker arm is mounted on the two conical roller bearings. Compared with the prior art, the turning transitional rocker arm has the advantages of convenience in assembling, flexibility in rotation, less friction force, simple process, high precision and the like, problems of abrasion and replacement of a lining are avoided, and abrasion of the conical roller bearings can be reduced via adding lubricating grease.
Description
Technical field
The utility model relates to a kind of motor turning accessory, especially relates to a kind of transition rocking arm that turns to.
Background technology
More the passenger vehicle intermediate rockers adopts and adds the lining form in the plumbing arm hole at present, but there is following defective in this structure:
Lining weares and teares easily;
1, the material capability of lining requires high;
2, assembly technology complexity, the making error is big;
3, tolerance strictness is difficult to guarantee;
4, cause endplay excessive after the liner wear, thereby influence the squareness of plumbing arm, steering drag link path of motion is changed;
5, change difficulty after the liner wear;
6, lining and axle are little free-running fit, and friction drag is big.
The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of easy to assembly, friction force is little, reduce wear turn to the transition rocking arm.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of transition rocking arm that turns to, the intermediate rockers that comprises rocker arm bracket, is welded in the rocker shaft in the rocker arm bracket and is connected the rocker arm bracket below is equipped with two tapered roller bearings on the described rocker shaft.
The outboard end of described tapered roller bearing is provided with seal ring and back-up ring.
Described intermediate rockers is installed on two tapered roller bearings.
The upper end of described intermediate rockers is provided with curved neck grease tap.
Be marked with grease in the gap between described intermediate rockers and the tapered roller bearing, this grease injects through curved neck grease tap.
Compared with prior art, the utility model case adopts tapered roller bearing to replace lining, and seal ring is installed at two ends, increases curved neck lubrication adapter.Grease up reduces wear and friction drag, has overcome the defective that adopts bush structure, has the following advantages:
(1) easy to assembly;
(2) rotate flexibly, friction force is little;
(3) technology is simple, the precision height;
(4) there is not the problem of liner wear and replacing;
(5) add grease, reduce the wearing and tearing of bearing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is that rocker arm bracket, 2 is that rocker shaft, 3 is that intermediate rockers, 4 is that back-up ring, 5 is that tapered roller bearing, 7 is seal ring for bending neck grease tap, 6.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of transition rocking arm that turns to, its structure as shown in Figure 1, the intermediate rockers 3 that comprises rocker arm bracket 1, is welded in the rocker shaft 2 in the rocker arm bracket and is connected rocker arm bracket 1 below, the outboard end that 6, two tapered roller bearings 6 of two tapered roller bearings are installed at rocker shaft 2 is provided with seal ring 7 and back-up ring 4.Intermediate rockers 3 is installed on two tapered roller bearings 6, is provided with curved neck grease tap 5 in addition in the upper end of intermediate rockers 3, injects grease through curved neck grease tap 5 in the gap between intermediate rockers 3 and the tapered roller bearing 6.
Turning to the transition rocking arm is critical component in the automobile steering system, drag link before and after it is connecting, it is the center-point that the back drag link is beated, the power that bear in this place is very big, so require very high to the rocking arm connecting portion, if it is excessive to wear and tear herein, cause the gap to increase, will directly have influence on the rideability of car load.
This programme adopts tapered roller bearing to replace lining, and seal ring is installed at two ends, increases curved neck lubrication adapter.Grease up reduces wear and friction drag.Overcome the defective that adopts bush structure.
Claims (5)
