Abstract
The rubber joint of counteracting rod in back automobile axle includes one rotating shaft, one inner bushing outside the rotating shaft, one outer bushing, one rubber layer between the inner bushing and the outer bushing. One oil filling nozzle in one end of the rotating shaft is communicated with the inside channel of the rotating shaft, and one oil outlet is set in the contact part between the rotating shaft and the inner bushing. The present invention makes it possible to refill lubricant oil to the contact part between the rotating shaft and the inner bushing without need of detaching the rotating shaft and the inner bushing.
Description
Technical field
The present invention relates to a kind of vehicular spare parts, relate in particular to a kind of rubber joint of counteracting rod in back automobile axle.
Background technology
At present, the back axle rubber joint of counteracting rod in back that uses on the automobile, its inner ring sleeve is cylinder-like structure with outer ring set, is filled with rubber layer between inner ring sleeve and the outer ring set, and turning cylinder is housed in the inner ring sleeve.In use, turning cylinder bears axially or application force radially.In use for some time, under the continuous extruding of radial effect power, outer ring set and rubber layer are thrown off easily, and rub through long between turning cylinder and the inner ring sleeve, and the lubricant between turning cylinder and the inner ring sleeve is almost used up, owing under the situation of not taking rubber nipple apart, can't add lubricant, therefore the lubricant effect of turning cylinder and inner ring sleeve is not fine, causes the wearing and tearing aggravation, and the gap between turning cylinder and the inner ring sleeve increases gradually, so that can't use, service life is shorter.
Summary of the invention
The object of the present invention is to provide a kind of rubber joint of counteracting rod in back automobile axle, it has in the advantage that just can add lubricant under the situation of not taking rubber nipple apart between inner ring sleeve and turning cylinder.。
The technical solution adopted for the present invention to solve the technical problems is: rubber joint of counteracting rod in back automobile axle, comprise turning cylinder, turning cylinder is installed in the inner ring sleeve, the outer cover of inner ring sleeve is equipped with outer ring set, be provided with rubber layer between inner ring sleeve and the outer ring set, one end of described turning cylinder is provided with zerk, zerk be opened in turning cylinder in-to-in channel connection, on turning cylinder, offer the oil outlet that is connected with passage with the contacted position of inner ring sleeve.
Above-mentioned zerk adopts one-way valve structures.
Offer groove on the inwall of above-mentioned inner ring sleeve.
Offer three parallel grooves on the inwall of above-mentioned inner ring sleeve.
Offer groove on the outer wall of above-mentioned inner ring sleeve.
Offer groove on the inwall of above-mentioned outer ring set.
Groove on the above-mentioned inner ring sleeve outer wall equates with recess width on the outer ring set inwall, and all scribbles adhesion agent.
Offer annular groove with the position that contacts of inner ring sleeve on the above-mentioned turning cylinder, be provided with clamp in the groove.
Be provided with backing plate between above-mentioned clamp and the inner ring sleeve.
The two ends that above-mentioned turning cylinder is exposed at the inner ring sleeve outside respectively offer two symmetrical tangent planes vertically, offer through hole on the tangent plane, are provided with bolt in the through hole.
The invention has the beneficial effects as follows: owing to be provided with zerk at an end of turning cylinder, zerk is communicated with oil outlet by being opened in turning cylinder in-to-in passage, oil outlet is positioned at inner ring sleeve, therefore can be under the situation of not taking rubber nipple apart, inject lubricating oil by zerk to the connecting portion of turning cylinder and inner ring sleeve, prevent that turning cylinder is excessive in the short time wearing and tearing, prolonged service life; Simultaneously on the inwall of the outer wall of inner ring sleeve and outer ring set, offer corresponding groove, be filled with rubber layer between the groove, prevented disengagement mutually between outer ring set, rubber layer and the inner ring sleeve, prolonged service life.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is vertical semisectional view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing 1,2 couples of the present invention are described in further detail: rubber joint of counteracting rod in back automobile axle, comprise turning cylinder 1, the middle part of turning cylinder 1 is equipped with inner ring sleeve 2, offer three parallel grooves 21 on the inwall of inner ring sleeve 2, offer groove 22 on the outer wall of inner ring sleeve 2, the outer cover of inner ring sleeve 2 is equipped with outer ring set 3, offer groove 31 on the inwall of outer ring set 3, inner ring sleeve 2 and outside be filled with rubber layer 4 between the ring set 3, in order to make rubber layer 4 and inner ring sleeve 2 and outer ring set 3 closed contacts, on the outer wall of inner ring sleeve 2 and outside be coated with adhesion agent on the inwall of ring set 3, offer groove 31 on the inwall of outer ring set 3, rubber layer 4 is filled in the groove 31, throws off with rubber layer 4 owing to be subjected to radial effect power but actv. prevents outer ring set 3; End at turning cylinder 1 is provided with zerk 11, zerk 11 be opened in turning cylinder 1 in-to-in passage 12 and be communicated with, the other end of passage 12 is communicated with the oil outlet 13 that is opened in turning cylinder 1 middle part, oil outlet 13 is nested with in inner ring sleeve 2, lubricating oil can be by zerk 11 by passage 12 and oil outlet 13, be injected into the contact site of turning cylinder 1 and inner ring sleeve 2, actv. has reduced the undue wear of turning cylinder 1 with inner ring sleeve 2, prolonged service life, can store some lubricating oils in the groove 21 on inner ring sleeve 2 inwalls simultaneously, in turning cylinder 1 rotation process, the lubricating oil in the groove 21 is brought on the contact surface of inner ring sleeve 2 and turning cylinder 1, has played lubricated effect, reduced friction, prolonged the service life of rubber nipple, zerk 11 adopts one-way valve structures, has prevented that lubricating oil from flowing backwards in passage 12; Place, contact site with the both ends of the surface of inner ring sleeve 2 on turning cylinder 1 offers annular groove 14, be provided with clamp 15 in the annular groove 14, be provided with backing plate 16 between the end face of clamp 15 and inner ring sleeve 2, but clamp 15 and backing plate 16 actvies prevent that inner ring sleeve 2 from moving axially along turning cylinder 1; Respectively offer a pair of symmetrical vertically tangent plane 5 at the both ends of turning cylinder 1, offer through hole 6 on the tangent plane 5, be provided with the bolt (not shown) in the through hole 6, nut and tangent plane closed contact seal through hole, through hole 6 is divided into two sections with passage 12, lubricating oil flow in the hypomere passage along slit between the screw thread after flowing out from the epimere passage, flows between turning cylinder and the inner ring sleeve again.
