Abstract
The utility model provides an integrated distance rod rubber joint assembly which comprises a support shaft, a rubber body and a jacket; a sphere is arranged in the middle position of the support shaft; an accommodating groove of which two ends are closed is formed in the inner circle of the jacket; the rubber body is vulcanized between the sphere in the middle position of the support shaft and the jacket, and is axially limited with the accommodating groove of the jacket through the sphere in the middle position of the support shaft; the support shaft, the rubber body and the jacket adopt an integrated structure. Through the reasonable structure arrangement, the rubber body is vulcanized between the jacket and the support shaft, and the rubber body and the support shaft as well as the rubber body and the support shaft do not fall off during the stress of the rubber body, so that the reliable connection is realized; only three parts are adopted, and compared with the prior art, the structure is simplified remarkably, and the production cost is reduced considerably.
Description
Technical field
The utility model relates to the track bar between the lorry doube bridge, the integrated rubber joint for thrust rod assembly especially be connected with track bar.
Background technique
Track bar between the lorry doube bridge, for guiding and power transmission, will bear multidirectional power, stress-bearing capability and intensity that this just requires connected rubber joint for thrust rod assembly to have in lorry telemechanical process.
Existing a kind of rubber joint for thrust rod assembly, as shown in Figure 1, nylon lining 2 is tightly placed on back shaft 1, and inner sleeve 4 is tightly placed on nylon lining 2, and inner sleeve 4 two ends are spacing with jump ring 7 by back-up ring 6, axle, and rubber body 3 is vulcanized between overcoat 5 and inner sleeve 4.The rubber joint for thrust rod assembly of this structure, the cylindrical of inner sleeve 4 is straight-through axle journals, there is no the axial limiting flange, the interior fenestra of overcoat 5 is straight-through axle journals, there is no the axial limiting flange, rubber body just sulfuration, between overcoat 5 and inner sleeve 4, does not have axial limiting, easily come off between stressed middle rubber body sulfuration and overcoat 5 and inner sleeve 4, cause inefficacy; Assembly part is more, complex structure, and cost of production is high.
Summary of the invention
In order to realize reliable connection, simplify product structure, reduce production costs, the utility model proposes integrated rubber joint for thrust rod assembly.
For this reason, the utility model is by the following technical solutions: integrated rubber joint for thrust rod assembly, it is characterized in that: by back shaft, rubber body, overcoat, formed, the neutral position of back shaft is provided with spheroid, the inner circle of overcoat is provided with the receiving groove of closed at both ends, rubber body is vulcanized between the spheroid and overcoat of back shaft, and rubber body realizes axial limiting by the spheroid of described back shaft and the receiving groove of overcoat, back shaft, rubber body, being integrally formed of overcoat structure.
Beneficial effect: the utility model is by rational structure setting, and rubber body is vulcanized reliably between overcoat and back shaft, can not come off between stressed middle rubber body and overcoat and back shaft, thereby realize reliable the connection; The utility model only adopts three parts, and compared with prior art, structure is significantly simplified, and has significantly reduced cost of production.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing rubber joint for thrust rod assembly.
Fig. 2 is the structural representation of the integrated rubber joint for thrust rod assembly of the utility model.
Fig. 3 is the structural drawing of overcoat in the integrated rubber joint for thrust rod assembly of the utility model.
Embodiment
As shown in Figure 2, further describe the utility model as follows: integrated rubber joint for thrust rod assembly, by back shaft 8, rubber body 9, overcoat 10, formed, the neutral position of back shaft 8 is provided with spheroid 8a, the inner circle of overcoat 10 is provided with the receiving groove of closed at both ends, rubber body 9 is vulcanized between the spheroid 8a and overcoat 10 of back shaft, and rubber body 9 realizes axial limiting by the spheroid 8a of described back shaft and the receiving groove of overcoat, back shaft 8, rubber body 9, overcoat 10 being integrally formed structures.
As shown in Figure 3, the inside circular arc bending of two end 10a of overcoat 10 and 10b, form the receiving groove 10c that outer imperial palace is little; The receiving groove of this structure is constantly realized axial limiting, can also realize radially spacing.
In the utility model, the receiving groove of overcoat 10 is not limited to this, as long as receiving groove is closed at both ends, can achieve the goal.
Claims (2)
