Description
Technical Field
The utility model relates to the technical field of steering mechanisms, in particular to a novel steering mechanism lubricating system.
Background
At present, lubricating of the steering knuckle bearing of the forklift truck is achieved through grease nozzles at the upper end and the lower end of the main pin to be filled with oil, and the lubricating oil reaches the bearing position through side holes of the main pin. However, in the steering axle with the sensor, the sensor is arranged at the upper end of the main pin, the grease nipple cannot be arranged, the grease cannot be injected at the upper end of the main pin, and the problem of poor grease injection effect exists when the grease is injected from the lower end of the main pin because the length of the main pin is longer.
Disclosure of Invention
In order to solve the technical problems, the utility model provides a novel steering mechanism lubricating system.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a novel steering mechanism lubricating system, includes main pin seat, sets up the king pin in main pin seat, be located the kingpin bearing between king pin seat and the king pin, the cover establish on the king pin and with king pin seat fixed connection's thrust ball bearing, set up the king pin hole in the king pin to and set up king pin oil inlet and the king pin oil-out that just communicates with the king pin hole in the king pin circumference.
Further, only one main pin hole is arranged at the upper part of the main pin; the position of the main pin oil outlet is higher than the lower end of the needle bearing and the thrust ball bearing.
Further, two main pin oil outlets are arranged and are arranged at the upper part of the main pin oil inlet.
Further, a knuckle connected to the kingpin is also included.
Compared with the prior art, the utility model has the beneficial technical effects that:
according to the utility model, the oiling position is changed, the oiling of the upper end and the lower end of the original main pin is changed into the oiling of the middle end of the main pin, the oiling quality of the main pin with a sensor is improved, and the lubricating grease is ensured to effectively reach the bearing of the upper main pin seat.
Drawings
FIG. 1 is a schematic view of the overall structure of the present utility model;
fig. 2 is a cross-sectional view at A-A in fig. 1.
Detailed Description
A preferred embodiment of the present utility model will be described in detail with reference to the accompanying drawings.
In the prior art, lubrication is difficult to realize on a steering axle provided with a sensor, and if oiling is carried out at the lower end of a main pin, the upper main pin seat bearing is difficult to reach due to the longer path.
1-2, the novel steering mechanism lubricating system comprises a main pin seat 4, a main pin 3 arranged in the main pin seat, a needle bearing 1 positioned between the main pin seat and the main pin, a thrust ball bearing 5 sleeved on the main pin and fixedly connected with the main pin seat, a main pin hole 8 arranged in the main pin, and a main pin oil inlet 7 and a main pin oil outlet 2 which are arranged in the circumferential direction of the main pin and are communicated with the main pin hole.
The needle roller bearings are uniformly distributed in the circumferential direction of the main pin, and the thrust ball bearings are sleeved on the main pin, so that the main pin can rotate around the main pin seat.
According to the utility model, the oiling position is changed, the oiling of the upper end and the lower end of the original main pin is changed into the oiling of the middle end of the main pin, the oiling quality of the main pin with a sensor is improved, and the lubricating grease is ensured to effectively reach the bearing of the upper main pin seat.
The main pin seat is contacted with the main pin through the needle bearing, and the lubricating grease is injected into the main pin hole through the position of the main pin oil inlet, and because of the large injection pressure, the lubricating grease in the main pin hole can be injected into the needle bearing and the thrust ball bearing through the main pin oil outlet, and when the knuckle rotates, the lubricating grease can be uniformly distributed to all parts of the needle bearing and the thrust ball bearing, thereby achieving the purpose of lubrication.
As shown in fig. 1, only one main pin hole is provided at the upper portion of the main pin; the position of the main pin oil outlet is higher than the lower end of the needle bearing and the thrust ball bearing.
The strength of the main pin after the main pin holes are opened on both sides is insufficient, so that the early failure of the main pin is easy to occur, and the labor time is increased in the main pin processing process; according to the utility model, the double-side hole opening of the master pin in the prior art is changed into the single-side hole opening, so that the strength of the master pin is improved, and the processing cost is reduced.
The position of the main pin oil outlet is higher than that of the needle roller bearing and the thrust ball bearing, and after the lubricating grease flows out from the main pin oil outlet, the lubricating grease can reach the needle roller bearing and the thrust ball bearing more quickly by means of gravity.
As shown in FIG. 2, two main pin oil outlets are arranged at the upper part of the main pin oil inlet.
As shown in fig. 1, further comprises a knuckle 6 connected to the kingpin.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a single embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to specific embodiments, and that the embodiments may be combined appropriately to form other embodiments that will be understood by those skilled in the art.
