Abstract
The utility model discloses a guide ring for a steel structural piston of an automobile brake chamber. The guide ring comprises a guide ring body, wherein a first ring body and a second ring body are distributed up and down along the axial direction of the guide ring body, and more than two flanges are uniformly distributed on the internal circumferential surface of the first ring body or the second ring body. The steel structural piston is tightly clamped by the guide ring through a flange structure, so that displacement and a clearance between the guide ring and the steel structural piston are prevented, and the service lives of the guide ring and the steel structural piston are prolonged.
Description
Technical field
The utility model relates to a kind of guide ring, relates in particular to the steel structure piston guide ring of automobile brake chamber.
Background technique
Guide ring, as a kind of mechanical part commonly used, is widely used in the fields such as automobile component manufacture, machining.For the steel structure piston of automobile brake chamber, because the steel structure piston needs continuous to-and-fro motion, require thus connected guide ring, must there is annexation very closely with the steel structure piston.Once because guide ring and steel structure piston produce gap, often cause the guide ring heel and toe wear, thereby affected steel structure piston movement locus and normal working life accurately.
Chinese invention patent application number 03132174.7 discloses a kind of piston type oil cylinder guiding ring, it is vertically to make groove on copper coin, groove partly matches with the annular projection on the piston of installing, again the inside diameter on demand of copper coin concave surface is wound into to ring-type, makes with copper coin and roll the piston type oil cylinder guiding ring be rolled into.This kind of guide ring do not propose how to improve the tight connectivity problem of guide ring and piston.
Summary of the invention
The utility model provides the steel structure piston guide ring of the automobile brake chamber of a kind of simple in structure, long service life, stable performance.
A kind of steel structure piston guide ring of automobile brake chamber, comprise the guide ring ring body, described guide ring ring body is being axially arranged with the first ring body and the second ring body distributed up and down, be evenly equipped with plural flange on the first ring body or the second ring body inside circumference face, hold closely the steel structure piston tightly by flanged structure, prevent that guide ring and steel structure piston are subjected to displacement, gap, extended the working life of guide ring and steel structure piston.
Described flange is plastics.Be plastics as preferred described the first ring body of structure and the second ring body.Think and adapt to a kind of preferred mounting type: be i.e. be sleeved in the piston respective grooves after guide ring heating, and buckle into steel structure piston respective grooves step place by flanged structure, naturally cooling rear and piston composition one.The relative traditional direction ring structure of this guide ring: it pack into solid and reliable after piston, can not produce obscission when brake chamber is assembled.
The utility model is held the steel structure piston tightly closely by flanged structure, prevents that guide ring and steel structure piston are subjected to displacement, gap, has extended the working life of guide ring and steel structure piston.
The accompanying drawing explanation
Be illustrated in figure 1 the guide ring master TV structure schematic diagram for the steel structure piston of the utility model automobile brake chamber.
Embodiment
A kind of steel structure piston guide ring of automobile brake chamber as shown in Figure 1, comprise guide ring ring body 1, guide ring ring body 1, being axially arranged with the first ring body and the second ring body distributed up and down, is evenly equipped with plural flange 2 on the first ring body or the second ring body inside circumference face.
As structure preferred flange 2, be plastics.Be plastics as further structure the first ring body and the second ring body.Think and adapt to a kind of preferred mounting type: be i.e. be sleeved in the piston respective grooves after guide ring heating, and buckle into steel structure piston respective grooves step place by flange 2 structures, naturally cooling rear and piston composition one.The relative traditional direction ring structure of this guide ring: it pack into solid and reliable after piston, can not produce obscission when brake chamber is assembled.
