Abstract
The present invention discloses an automatic lubricating oil leading-in sliding bearing of a shock absorber. The surface of the friction pair of the sliding bearing is provided with a lubricating oil groove net, and the upper end of the lubricating oil groove of the sliding bearing used for holes has a proper distance from the upper end surface of the sliding bearing; a communicating groove is formed between the lower end of the lubricating oil groove and the lubricating oil source of the shock absorber, and the lower end of the lubricating oil groove of the sliding bearing used for a shaft has a proper distance from the lower end surface of the sliding bearing; a communicating groove is arranged between the upper end of the lubricating oil groove and the lubricating oil source. When the shock absorber operates, a continuous integral lubricating oil film is formed on each of the friction pairs of the sliding bearing used for holes and the sliding bearing used for a shaft so as to reduce the abrasion and enhance service performance.
Description
Technical field
The present invention relates to a kind of vehicle shock absorber sliding bearing of leading-in lubricating oil by itself.
Background technique
The used useful composite material manufacturing of sliding bearing in the modern vehicle vibration damper, form or metallic sintered products by steel backing one bronze engineering plastics, or Cuprum alloy or cast iron materials, performance with certain selflubricating, wear-resistant, low coefficient of friction, but because lubricant oil can not enter at a high speed, the surface of friction pair of big pressure, working life is shorter, causes vehicle shock absorber to be scrapped in advance, has influenced the use of vehicle shock absorber and the raising of performance.
Summary of the invention
A kind of vehicle shock absorber sliding bearing of leading-in lubricating oil by itself, it is characterized in that: the surface of friction pair of sliding bearing is furnished with lubricant oil groove net, there is suitable distance in the hole with the oil cavity slot pitch sliding bearing upper-end surface of sliding bearing, be provided with between lubricant oil groove and source of lubrication and be communicated with groove, axle has suitable distance with the sliding bearing lubricating oil groove apart from the sliding bearing lower end surface, be provided with between lubricant oil groove and source of lubrication and be communicated with groove, the lubricant oil groove that the sliding bearing surface of friction pair is arranged can be lateral trench or longitudinal groove or broken line groove or camber line groove or " ∞ " font groove or netted groove.
The vehicle shock absorber sliding bearing that the purpose of this invention is to provide a kind of leading-in lubricating oil by itself, the sliding bearing surface of friction pair is furnished with the groove net that imports lubricant oil, thereby make the sliding bearing surface of friction pair form continuous, a complete oil film at work, prolong working life, improved usability.
Advantage of the present invention:
Owing to be furnished with lubricant oil groove net on the friction pair surface of the vehicle shock absorber sliding bearing of leading-in lubricating oil by itself, when vibration damper is worked, lubricant oil in the source of lubrication enters lubricant oil groove net through being communicated with groove, make and form continuous, a complete oil film between surface of friction pair, friction pair are reduced wear, increase working life, improved usability, reached purpose of the present invention.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional view (partly cuing open) of Fig. 1;
Fig. 3 is the B-B sectional view (part) of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the present invention is further elaborated.
The hole elaborates with the vehicle shock absorber sliding bearing of leading-in lubricating oil by itself:
Present embodiment is the partial schematic diagram (consulting Fig. 1) of the application of the present invention on vehicle shock absorber, comprise oil storage cylinder 1, clutch release slave cylinder 2, hole sliding bearing 4, guider 6 and piston rod 10, being source of lubrication 3 between piston rod and the clutch release slave cylinder, is high pressure oil area during work.Guider 6 is the support connecting piece of oil storage cylinder and clutch release slave cylinder, low pressure oil district 7 is between guider and piston rod, guider is provided with spill port 5, the hole is fitted in guider 6 holes with sliding bearing 4, piston rod 10 constitutes friction pair with the hole with sliding bearing 4 endoporus, surface of friction pair at sliding bearing is furnished with lubricant oil groove 8 (Fig. 1, Fig. 2), the periphery of groove 8 is rectangular shaped as frame, the groove middle part is " ∞ " font, and the place, summit of " ∞ " font groove communicates with being communicated with groove 9, evenly distributes along friction pair, interconnect, form a lubricant oil groove net, there is suitable distance oil cavity slot pitch sliding bearing upper-end surface, has prevented that effectively the high pressure oil of source of lubrication 3 from leaking into low pressure oil district 7, the lubricant oil groove is communicated with source of lubrication 3 through being communicated with groove 9, is communicated with groove 9 and also plays a part oil groove.When vehicle shock absorber is worked, lubricant oil in the source of lubrication enters lubricant oil groove net through connecting groove 9, formation one continuous, the complete lubricant film between sliding bearing at piston rod and hole, thus wearing and tearing alleviated, prolong working life and improved usability.Ooze in the work in the less amount of lubrication oil in low pressure oil district and can flow back to oil storage cylinder through spill port 5.Being communicated with groove 9 in the present embodiment is two, so that the lubricant oil in the lubricant oil groove net obtains replenishing of sufficient amount timely.
Axle elaborates with the vehicle shock absorber sliding bearing of leading-in lubricating oil by itself:
The bottom of present embodiment (consulting Fig. 1) is the vehicle shock absorber piston part schematic representation that does not cut open, position limit socket 11, spring sheet 12 and flowing valve 13 are installed in the upper end of piston 16, axle is installed in piston 16 circular grooves with sliding bearing 17, constitute friction pair with clutch release slave cylinder 2 in the work, axle is furnished with lubricant oil Oil Guide groove 14 (Fig. 1 with sliding bearing 17 surface of friction pair, Fig. 3), the periphery of groove is rectangular shaped as frame, the middle part of groove is " ∞ " font, the place, summit of " ∞ " font groove communicates with connection groove 15, evenly distribute along friction pair, interconnect, form a lubricant oil groove net, there is suitable distance oil cavity slot pitch sliding bearing lower end surface, prevents that effectively axle is with on the sliding bearing, the mutual leakage of following two ends oil, Oil Guide groove 14 is communicated with groove 15 make-up oils by two of communicating with source of lubrication 3, between axle is with sliding bearing friction surface and clutch release slave cylinder, form continuous, complete lubricant film, thus wearing and tearing alleviated, prolong working life and improved usability.Being communicated with groove 15 in the present embodiment is two, so that the lubricant oil in the lubricant oil groove net obtains replenishing of sufficient amount timely.
