A kind of leaf spring pin of heavy duty truck, comprise the leaf spring pin body of cylindrical structure, first end face of described leaf spring pin body is provided with dismounting groove, described first end face is located at the arrival end of the oil inlet passage of described leaf spring pin, and described leaf spring pin body is provided with accommodation space near one end of described arrival end, described accommodation space extends along the axis of described leaf spring pin body from described first end face, and the grease nozzle being connected to described arrival end is placed in described accommodation space.
Preferably, described dismounting groove is in-line groove, and described in-line groove runs through described first end face.
Preferably, the inwall of described oil inlet passage is provided with negative thread, and described grease nozzle is bolted in described inwall.
Preferably, the oil outlet of described oil inlet passage is provided with multiple, and each described oil outlet distributes along the circumference of described leaf spring pin body.
Preferably, the end of described leaf spring pin body is also provided with draw-in groove, and described draw-in groove also radially extends from the outer wall of described leaf spring pin body.
Preferably, described draw-in groove is provided with two, and draw-in groove described in two is located at the two ends of described leaf spring pin body respectively.
The beneficial effect that the utility model obtains is:
The utility model provides a kind of leaf spring pin of heavy duty truck, comprise the leaf spring pin body of cylindrical structure, first end face of described leaf spring pin body is provided with dismounting groove, described first end face is located at the arrival end of the oil inlet passage of described leaf spring pin, and described leaf spring pin body is provided with accommodation space near one end of described arrival end, described accommodation space extends along the axis of described leaf spring pin body from described first end face, and the grease nozzle being connected to described arrival end is placed in described accommodation space.Adopt this technical scheme, by arranging dismounting groove, the end of stripper can be placed in dismounting groove, and by rotating stripper and driving leaf spring pin to rotate, make it slowly deviate from leaf spring lining, to reduce destruction when dismantling leaf spring pin, simultaneously, accommodation space is that grease nozzle provides and dodges space, making it from colliding with, reducing its failure risk.

Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
Shown in composition graphs 2-4, the utility model provides a kind of leaf spring pin 10 of heavy duty truck, comprise the leaf spring pin body 11 of cylindrical structure, in order to solve the defect existed in prior art, the utility model has made following technology: the first end face 111 of leaf spring pin body 11 is provided with dismounting groove 12, first end face 111 is located at the arrival end of the oil inlet passage 13 of leaf spring pin 10, and leaf spring pin body 11 is provided with accommodation space 14 near one end of arrival end, accommodation space 14 extends along the axis of leaf spring pin body 11 from the first end face 111, the grease nozzle being connected to arrival end is placed in accommodation space 14.Adopt this technical scheme, by arranging dismounting groove, the end of stripper can be placed in dismounting groove, and drive leaf spring pin to rotate by rotating stripper, make leaf spring pin 10 slowly deviate from leaf spring lining, to reduce the destruction to leaf spring pin, simultaneously, accommodation space is that grease nozzle provides and dodges space, making it from colliding with, reducing failure risk.
In above-mentioned technical scheme, dismounting groove 12 is preferably in-line groove, and in-line groove runs through the first end face 111, this scheme can the coordinating of groove for convenience detach and conventional tool, as a word screwdriver etc., certainly, dismounting groove also can be set to other structures such as cross recess, and the utility model does not limit this.
