Abstract

The utility model provides a rubber joint assembly of a propelling rod, which comprises a supporting shaft, a nylon bush, an inner bushing, an outer bushing and a rubber body, wherein the nylon bush is tightly sleeved with the supporting shaft; the inner bushing is tightly sleeved with the nylon bush; two ends of the inner bushing are limited by a check ring and a shaft snap spring; the rubber body is vulcanized between the outer bushing and the inner bushing; ring slots are formed in the excircle of the inner bushing; accommodating grooves of which two ends are closed are formed in the inner circle of the outer bushing; the rubber body is axially limited through the ring slots and the accommodating grooves. Through the improvement on the structures of the outer bushing and the inner bushing, the rubber body is reliably vulcanized between the outer bushing and the inner bushing, and the rubber body and the outer bushing as well as the rubber body and the inner bushing cannot fall off during the stress of the rubber body, so that the reliable connection is realized.

Description

The rubber joint for thrust rod assembly

Technical field

The utility model relates to the track bar between the lorry doube bridge, the 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.

Summary of the invention

For fear of coming off between rubber body sulfuration and overcoat and inner sleeve, realize reliably connecting, the utility model proposes the rubber joint for thrust rod assembly.

For this reason, the utility model is by the following technical solutions: the rubber joint for thrust rod assembly, comprise back shaft, nylon lining, inner sleeve, overcoat, rubber body, nylon lining is tightly placed on back shaft, inner sleeve is tightly placed on nylon lining, the inner sleeve two ends are spacing with jump ring by back-up ring, axle, rubber body is vulcanized between overcoat and inner sleeve, it is characterized in that: the cylindrical of inner sleeve is provided with annular groove, the inner circle of overcoat is provided with the receiving groove of closed at both ends, and rubber body realizes axial limiting by described annular groove and receiving groove.

Beneficial effect: the utility model is improved the structure of overcoat and inner sleeve, and rubber body is vulcanized reliably between overcoat and inner sleeve, can not come off between stressed middle rubber body and overcoat and inner sleeve, thereby realize reliable the connection.

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 utility model rubber joint for thrust rod assembly.

Fig. 3 is the structural drawing of inner sleeve in the utility model rubber joint for thrust rod assembly.

Fig. 4 is the structural drawing of overcoat in the utility model rubber joint for thrust rod assembly.

Embodiment

As shown in Figure 2, further describe the utility model as follows: the rubber joint for thrust rod assembly, comprise back shaft 1, nylon lining 2, inner sleeve 4, overcoat 5, rubber body 3, nylon lining 2 is tightly placed on back shaft 1, inner sleeve 4 is tightly placed on nylon lining 2, 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.

As shown in Figure 2, Figure 3, Figure 4, the cylindrical of inner sleeve 4 is provided with annular groove 4a, and the inner circle of overcoat 5 is provided with the receiving groove 5c of closed at both ends, and rubber body 3 realizes axial limiting by described annular groove 4a and receiving groove 5c.

That on the cylindrical of inner sleeve 4, arrange as shown in Figure 3, is an annular groove 4a.The annular groove of inner sleeve 4 is not limited to this, can be also to be a determining deviation on the cylindrical of inner sleeve 4 to be provided with a plurality of annular grooves.

As shown in Figure 4, the inside circular arc bending of two end 5a of

overcoat

5 and 5b, form the receiving groove 5c 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 5 is not limited to this, as long as receiving groove is closed at both ends, can achieve the goal.

Claims

1. rubber joint for thrust rod assembly, comprise back shaft, nylon lining, inner sleeve, overcoat, rubber body, nylon lining is tightly placed on back shaft, inner sleeve is tightly placed on nylon lining, the inner sleeve two ends are spacing with jump ring by back-up ring, axle, and rubber body is vulcanized between overcoat and inner sleeve, it is characterized in that: the cylindrical of inner sleeve is provided with annular groove, the inner circle of overcoat is provided with the receiving groove of closed at both ends, and rubber body realizes axial limiting by described annular groove and receiving groove.

2. rubber joint for thrust rod assembly according to claim 1 is characterized in that: the inside circular arc bending in two ends of described overcoat forms the little receiving groove of outer imperial palace.

3. rubber joint for thrust rod assembly according to claim 1, it is characterized in that: the annular groove put in described is a plurality of, a plurality of annular grooves are a determining deviation setting on the cylindrical of inner sleeve.
