Description
Technical Field
The utility model relates to the field of shock absorbers, in particular to a shock absorber guide and an installation structure which are beneficial to noise improvement.
Background
The guider and the oil seal of the prior art are embedded together, the shock absorber is placed in the shock absorber, the lower end of the shock absorber is pressed into the working cylinder of the shock absorber, then the flanging sealing of the oil storage cylinder is carried out, the flanging of the actual oil storage cylinder is pressed on the end face of the guider, and the parts such as the guider, the working cylinder, the bottom valve and the like are fixed through a certain pre-pressure. The guide is constructed as shown in fig. 1, and the shock absorber is subjected to a lateral force during actual use, and the overcoming of the lateral force is completely dependent on the pre-compression force.
Through searching, chinese patent CN202468822U discloses a dustproof cover of a multipoint fixed integral shock absorber, and a groove is formed in the dustproof cover and is in multipoint interference fit with an oil storage cylinder, so that the pressure on an oil seal can be reduced, and the dustproof cover is also beneficial to fixing and clamping. The lower platform of the upper end surface groove is pressed in the sealing flanging area in a dispersing way, so that the protection of the oil seal body and the lip is facilitated. The above patent does not improve the ability of the shock absorber to resist lateral forces. The influence of lateral force is overcome by completely relying on the precompression of the flanging of the oil storage cylinder during sealing, the capability of overcoming the lateral force is limited relatively in practice, and particularly, the influence of large lateral force or high-frequency alternating lateral force can generate lateral displacement, looseness and the like, so that the knocking noise of the shock absorber body is caused.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a shock absorber guide and a mounting structure which are beneficial to noise improvement.
The aim of the utility model is achieved by the following technical scheme. A shock absorber guider favorable for noise improvement is used for being tightly attached to the flange of an oil storage cylinder and provided with a groove.
Further, the groove is an annular groove.
The utility model also provides a mounting structure of the shock absorber guide device, which comprises an oil storage cylinder, a working cylinder, a guide device and an oil seal, wherein the oil seal is connected with the guide device in a jogged manner, the lower end of the guide device is pressed in the working cylinder, and the flanging of the oil storage cylinder is tightly attached to the end face of the guide device; in the flanging sealing process, the raw material of the oil storage cylinder of the flanging part is tightly attached to the groove, and part of the raw material is embedded into the groove.
The beneficial effects of the utility model are as follows:
1. the fastening and the attaching of the flanging of the oil storage cylinder and the guide device during sealing are improved, and the capability of resisting the movement under the action of lateral force is improved.
2. Avoiding the risks of loose clearance and noise generation under larger lateral force.
3. The reliability and durability of the sealing flanging are improved.

Detailed Description
The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the embodiments described below or technical features may be arbitrarily combined to form new embodiments.
As shown in fig. 2-3, a shock absorber guide for improving noise is provided, wherein a groove 1-1, preferably an annular groove, is arranged on an end face 1-2 of the guide 1, which is used for being tightly attached to a flange 4-1 of an oil storage cylinder 4.
As shown in figures 4-5, the utility model also provides a mounting structure of the shock absorber guide, which comprises an oil storage cylinder 4, a dust cover 3, a piston rod 6, a working cylinder 5, a guide 1 and an oil seal 2, wherein the oil seal 2 is connected with the guide 1 in a jogged manner, the lower end of the guide 1 is pressed in the working cylinder 5, and a flanging 4-1 of the oil storage cylinder 4 is tightly attached to an end face 1-2 of the guide 1.
The end face of the turnup contact part of the traditional guide and the oil storage cylinder is additionally provided with a groove design, in the process of turnup sealing of an actual shock absorber, raw materials of the oil storage cylinder of the turnup part can be tightly attached to the groove 1-1, partial materials are embedded into the groove 1-1 for fixation, sealing of the sealing and lateral movement resistance after being subjected to lateral force are improved, knocking noise caused by lateral displacement of the shock absorber under the lateral force is avoided, and sealing property and durability of the sealing are improved.
