Abstract
The utility model belongs to endless-track vehicle rubber-metal track technical field, and in particular to a kind of crawler belt rubber-metal hinge with support ring limiting especially suitable for high speed tracked vehicle.The utility model provides overload protection by the way that support ring is set at the largest deformation of metal axis pin, to the rubber ring of rubber-metal hinge.It is compared to the prior art, the utility model can effectively prevent rubber ring to bear multiple overload stresses fatigue damage occurs, and ensure rubber ring stress in zone of reasonableness, so as to increase the reliability of rubber ring and service life.
Description
Technical field
The utility model belongs to endless-track vehicle rubber-metal track technical field, and in particular to one kind is especially suitable for height
The crawler belt rubber-metal hinge with support ring limiting of fast endless-track vehicle.
Background technology
To improve the efficiency of military high speed crawler belt, noise caused by reduction crawler belt improves the service life of crawler belt, military
The attachment device between rubber-metal hinge effect track plate is widely used in endless-track vehicle.
The service life of rubber-metal hinge crawler belt is generally dependent on the service life of rubber-metal hinge, and rubber-metal hinge
Service life again depend on rubber ring service life.Existing rubber-metal hinge is vulcanized using rubber ring in metallic pin or metal liner
It puts on, and is pressed into track pin ear together.The rubber ring of hinge is subjected to radial compression during press fitting, also subject to size
The Uniaxial Compression of the continually changing tension for acting on creeper tread.Simultaneously when creeper tread relatively rotates, rubber ring is also by side
Effect to the shearing force of variation.The fatigue rupture of rubber ring is general first to bear track tension effect from the inside of rubber ring
Start on one side, it and the amount of force, frequency, amplitude that are subject to etc. are related.As shown in Figure 1, existing double-pin type rubber-metal is carried out
The rubber-metal hinge of band uses an equal diameter metal axis pin 1 more, vulcanizes rubber ring 2 on metallic pin.
Utility model content
(1) technical problems to be solved
The utility model proposes a kind of crawler belt rubber-metal hinge with support ring limiting, to solve how to prevent rubber ring
The track tension being subject to is more than the maximum pressure that itself can be born, and ensures that rubber ring stress in reasonable controlled range, increases
Into rubber ring reliability and service life the technical issues of.
(2) technical solution
In order to solve the above-mentioned technical problem, the utility model proposes a kind of crawler belt rubber-metal hinges with support ring limiting
Chain, the hinge include metal axis pin, rubber ring and support ring；Wherein, rubber ring vulcanization is on metal axis pin；Support ring is arranged on
At the largest deformation of metal axis pin.
Further, support ring is welded on metal axis pin.
Further, support ring is integrally machined with metal axis pin.
Further, the maximum compressibility of rubber ring is 1.3mm-1.5mm.
Further, support ring inner ring and metal axis pin are rigidly connected, and there are 1.3- between support ring outer ring and creeper tread
1.5mm gap.
(3) advantageous effect
The utility model proposes with support ring limiting crawler belt rubber-metal hinge, by the way that support ring is set to metal
At the largest deformation of axis pin, overload protection is provided to the rubber ring of rubber-metal hinge.The prior art is compared to, this practicality is new
Type can effectively prevent rubber ring to bear multiple overload stresses fatigue damage occurs, and ensure rubber ring stress in zone of reasonableness, from
And increase the reliability and service life of rubber ring.
Description of the drawings
Fig. 1 is rubber-metal hinge schematic diagram in the prior art；
Fig. 2 is the utility model embodiment rubber-metal hinge schematic diagram；
Fig. 3 is the assembly schematic diagram of the utility model embodiment rubber-metal hinge and creeper tread；
Fig. 4 is the utility model embodiment rubber-metal hinge assemblies rear support ring partial enlarged view.
Specific embodiment
To make the purpose of this utility model, content and advantage clearer, with reference to the accompanying drawings and examples, to this practicality
Novel specific embodiment is described in further detail.
The present embodiment proposes a kind of crawler belt rubber-metal hinge with support ring limiting, as shown in Fig. 2, the hinge includes gold
Belong to axis pin 1, rubber ring 2 and support ring 3.Rubber ring 2 vulcanizes on metal axis pin 1, and support ring 3 is arranged on metal axis pin 1 most
At large deformation.Support ring 4 is welded on metal axis pin 1 or is directly integrally machined with metal axis pin 1.
In the rubber-metal hinge of the present embodiment, the structure and function of rubber ring 2 does not change, with the prior art
The difference lies in：Four support rings 3 are increased on metal axis pin 1.After rubber-metal hinge is press-fitted into creeper tread 4, rubber
Cushion rubber 2 is deformed into the state as shown in label 5 in Fig. 3.According to the service condition of vehicle, the maximum compressibility of rubber ring 2 is
1.3mm-1.5mm.There are the gap of 1.3-1.5mm between 3 outer ring of support ring and track plate, as shown in Figure 4.When crawler belt is born
During tractive force, rubber ring 2 is further compressed, and distance of the support ring 3 apart from creeper tread 4 is gradually reduced.When the work that crawler belt is subject to
When firmly exceeding scope of design, support ring 3 and track plate contact provide stable support force, ensure the pressure that rubber ring is born
Contracting amount is avoided rubber ring 2 from bearing excessive pressure and be destroyed, improves the rigidity of metal axis pin 1, reduce gold in scope of design
Belong to deformation quantity of the axis pin 1 when bearing tractive force, promote the reliability and service life of rubber ring.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, under the premise of the utility model technical principle is not departed from, several improvement and deformation can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
