Description
Technical field
The utility model relates to heavy duty truck propons upper-part, is specifically related to a kind of front axle main pin blanking cover mounting structure.
Background technology
At present, the turning member that heavily blocks propons generally comprises front axle, steering swivel and stub, steering swivel is flexibly connected with front axle fist end by stub, and lining is equipped with respectively in the upper and lower of stub, and the blanking cover with alemite is equipped with respectively in end, upper end and the end, lower end of stub.In vehicle routine use, by alemite, to the upper and lower lining grease up of stub, to play the effect of lubricated stub, and on stub two ends, the effect of blanking cover is for preventing that dust and impurity from entering and pollution lubricating fat, causes the wearing and tearing of stub and lining.There are the following problems in actual use for this kind of front axle main pin blanking cover:
1, the blanking cover on front axle main pin in use easily comes off, and internal lubrication fat can cause leakage, and is subject to contaminating impurity.
2, after blanking cover is first fixed on stub, then alemite is installed on blanking cover, assembling is comparatively complicated, and cost is higher.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one can effectively prevent that master pin closure from coming off, and blanking cover installation reliability is good, can simplify assembly technology, the front axle main pin blanking cover mounting structure reducing costs simultaneously.
To achieve these goals, the technical solution adopted in the utility model is:
This front axle main pin blanking cover mounting structure, comprise the stub for connecting front axle and steering swivel, on described stub two ends, be respectively equipped with the first blanking cover and the second blanking cover, described the first blanking cover is connected by hollow bolt with described stub, and described hollow bolt is provided with alemite; Described the second blanking cover is pressed on described stub by the jump ring being arranged on described steering swivel.
Described stub center is provided with through hole, and described hollow bolt and described through hole are connected.
Described the second blanking cover is provided with the alemite communicating with described through hole.
The end, one end that described through hole and described hollow bolt are connected is horn structure.
The utility model has the advantage of: this front axle main pin blanking cover mounting structure, adopt hollow bolt to realize the fixing of the first blanking cover on stub one end, adopt jump ring to realize the fixing of the second blanking cover on the stub other end; Hollow bolt and jump ring are firmly arranged on two blanking covers on stub on stub two ends, and the installation reliability of blanking cover is good, can effectively solve in driving process, and the problem that master pin closure comes off, to prevent that stub internal lubrication fat from revealing and pollution; Go up alemite is arranged on hollow bolt simultaneously, hollow bolt can fixedly secure the first blanking cover on stub on the one hand, replace on the other hand existing blanking cover and alemite and separated fixing arrangement, structure is simpler, reduced number of parts and assembly process, and cost is lower simultaneously.
Further, stub axially extending bore, has strengthened the oil storage space of stub inside, has reduced grease adding number of times, has saved maintenance cost.
Brief description of the drawings
Mark in content and the figure below each width accompanying drawing of the utility model specification sheets being expressed is briefly described:
Fig. 1 is the structural representation of the utility model front axle main pin blanking cover mounting structure.
Mark in above-mentioned figure is:
1, steering swivel, 2, the first blanking cover, 3, hollow bolt, 4, upper alemite, 5, stub, 6, front axle, 7, the second blanking cover, 8, jump ring, 9, lower alemite, 10, through hole.
Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, this front axle main pin blanking cover mounting structure, comprise the stub 5 for connecting front axle 6 and steering swivel 1, blanking cover comprises the first blanking cover 2 and the second blanking cover 7 that are located on stub 5 two ends, the first blanking cover 2 is connected by hollow bolt 3 with stub 5, hollow bolt 3 is provided with alemite (upper alemite 4 shown in Fig. 1), and grease enters the interior realization of stub 5 by hollow bolt 3 and lubricates; On front axle main pin 5 one end the first blanking covers 2, increase a hollow bolt 3 that alemite is housed, hollow bolt 3 is realized fixing and stub 5 grease addings of the first blanking cover 2 simultaneously; The second blanking cover 7 is pressed on stub 5 by the jump ring 8 being arranged on steering swivel 1.
This front axle main pin blanking cover mounting structure, adopts hollow bolt 3 to realize the fixing of the first blanking cover 2 on stub 5 one end, adopts jump ring 8 to realize the fixing of the second blanking cover 7 on stub 5 other ends; Hollow bolt 3 and jump ring 8 are firmly arranged on two blanking covers on stub 5 on stub 5 two ends, can effectively solve in driving process, and the problem that stub 5 blanking covers come off, to prevent stub 5 internal lubrication fat leakages; Further, upper alemite 4 is arranged on hollow bolt 3, hollow bolt 3 can fixedly secure the first blanking cover 2 on stub 5 on the one hand, replace on the other hand existing blanking cover and alemite and separated fixing arrangement, structure is simpler, reduced number of parts and assembly process, and cost is lower simultaneously.
Stub 5 centers are provided with through hole 10, and hollow bolt 3 and through hole 10 communicate.Axially extending bore 10 on stub 5, has strengthened the oil storage space of stub 5 inside, has reduced grease adding number of times, in raising the efficiency, has further saved maintenance cost.
The second blanking cover 7 being pressed on stub 5 by jump ring 8 is provided with the alemite (lower alemite 9 shown in Fig. 1) communicating with through hole 10.Lower alemite 9 adds lubricating oil to enter in through hole 10, realizes the lubricated of stub 5.
The end, one end that through hole 10 and hollow bolt 3 are connected is taper, be that the end, one end that through hole 10 and hollow bolt 3 are connected is horn structure, to ensure that the grease entering from hollow bolt 3 can all enter in through hole 10, to ensure further the lubricant effect of stub 5.
This front axle main pin blanking cover mounting structure, steering swivel 1 is connected on front axle 6 by stub 5, then with hollow bolt 3, the first blanking cover 2 on stub 5 one end is connected on stub 5, and upper alemite 4 is tightened in above hollow bolt 3; The second blanking cover 7 on stub 5 other ends is fixed on stub 5 with jump ring 8, more lower alemite 9 is tightened in above the second blanking cover 7 of stub 5.
Use after a period of time at vehicle, to the inner grease up of stub 5, in stub 5, be provided with the through hole 10 of storing lubricating grease by the upper alemite 4 on stub 5 two ends and lower alemite 9, strengthened the oil storage space of stub 5 inside, reduce grease adding number of times, saved maintenance cost.
On stub 5, the first blanking cover 2 adopts the mode of hollow bolt 3 direct integrated alemites to fix, and replaces existing blanking cover and alemite and separates fixing arrangement, and this structure is simpler, reduced number of parts and assembly process, and cost is lower simultaneously.
Obviously the utility model specific implementation is not subject to the restrictions described above, as long as adopted the improvement of the various unsubstantialities that method design of the present utility model and technical scheme carry out, all within protection domain of the present utility model.
