Assembly method of zd45s006 automobile shock absorber

Abstract

The invention discloses an assembling method for a ZD45S006 type automobile shock absorber. The assembling method comprises the steps that a piston rod, an oil seal, oil seal collars, a guide device,a limit sleeve, an oil storage barrel assembly, a piston assembly, a compression valve assembly and the like which are used for forming the ZD45S006 type automobile shock absorber are used for producing all parts according to the design size and accuracy requirements; in the assembling process, the oil seal is arranged at the determined position of the piston rod in a sleeving manner, and the oilseal collars are installed on the two sides of the oil seal, so that the oil seal is in sealing contact between the piston rod; and the guide device is arranged on the piston rod from one side of an oil seal face of the oil seal in a sleeving manner to be in place together with the oil seal correspondingly, and then the limit sleeve is connected to the determined position of the piston rod in a sleeving manner. The ZD45S006 type automobile shock absorber obtained by the assembling method ensures safe sealing between the oil seal and the piston rod, and the product quality problem can be foundin time, and the assembled product quality consistency is good, the rejection rate is low, and the service life is long.

Description

technical field [0001] The invention relates to a production method of a shock absorber, in particular to an assembly method of a ZD45S006 automobile shock absorber. Background technique [0002] At present, for the ZD45S006 automobile shock absorber, the installation method has always been to first fix the limit block at the determined position of the piston rod, then install the piston assembly at one end of the piston rod, and then install the piston assembly with the piston rod. Insert it into the working cylinder, then insert the guide at the other end with the limit block, and then install the oil seal. This kind of shock absorber assembly method often has the problem of oil seal leakage, and the installation accuracy and installation of various components The quality cannot be guaranteed through intermediate process inspections. When a problem is found, the entire shock absorber can only be scrapped and it is difficult to improve and refurbish it. For the connecting ...

[0002] At present, for the ZD45S006 automobile shock absorber, the installation method has always been to first fix the limit block at the determined position of the piston rod, then install the piston assembly at one end of the piston rod, and then install the piston assembly with the piston rod. Insert it into the working cylinder, then insert the guide at the other end with the limit block, and then install the oil seal. This kind of shock absorber assembly method often has the problem of oil seal leakage, and the installation accuracy and installation of various components The quality cannot be guaranteed through intermediate process inspections. When a problem is found, the entire shock absorber can only be scrapped and it is difficult to improve and refurbish it.

For the connecting rod buffer block, in the prior art, the connecting rod buffer block is directly inserted into the piston rod first, and then the dust cover provided with the dust cover collar is inserted into the connecting rod buffer block. This installation method, Difficult to design tooling to fit the boot collar into the rod bumper that is already mounted on the piston rod and often damages the boot
