When the value of H1 is bigger, mandrel 1 and dividing on valve overcoat 3 corresponding will also increase to the value of the matched position of above-mentioned size, and axle box is fixed
The load that position node can be born on lateral direction of car is bigger, and axial rigidity is bigger；Conversely, when the value of H1 is smaller, mandrel 1
Also corresponding to reduce to the value of the matched position of above-mentioned size with dividing on valve overcoat 3, axle box guidance joint can bear to come from car
Load in transverse direction is smaller, and axial rigidity is smaller.
The value of adjustment 2 each parameter of rubber layer further includes：Adjust angle A 1 between 2 inclined-plane 1 of rubber layer and inner concave,
Adjust the angle A 2 between 2 inclined-plane 2 22 of rubber layer and medial surface.Vertex is constant, and when the value of A1 is bigger, the value of D2 and then becomes
Greatly, the cushioning effect that can be played when axle box guidance joint bears the load on lateral direction of car is bigger, and damping effect is obvious, and
Axial rigidity is smaller；Conversely, when the value of A1 is smaller, the value of D2 and then diminishes, and axle box guidance joint bears to come from lateral direction of car
On load when the cushioning effect that can play it is smaller, damping effect weakens, and axial rigidity is bigger.Vertex is constant, when the value of A2
When bigger, the size of the mandrel 1 coordinated with it and then changes, and enables the axial load that axle box guidance joint is born bigger, axis
It is also bigger to rigidity；And when the value of A2 is smaller, the axial load that axle box guidance joint bears to come is smaller, and axial rigidity is also got over
It is small.
Relation between 2 each parameter of rubber layer is：A1 >=A2, L1≤L2.Both ensured axle box guidance joint can smoothly into
Luggage is matched somebody with somebody, and ensures there is higher stability after assembling is integral.
Mandrel 1, divide valve overcoat 3, integral sleeve 4 to be made of rigid material.
Between 2 each joint face of rubber layer and rubber layer 2 and mandrel 1 and divide valve overcoat 3 matching face between it is smoothed
Cross, fold or cracking are produced in junction when avoiding the rubber layer 2 from being squeezed.
Above example is only for illustration of the utility model, rather than the limitation to the utility model, related technical field
Technical staff in the case where not departing from the spirit and scope of the utility model, can also make a variety of changes or convert, because
This all equivalent technical solution should also belong to the scope of protection of the utility model, and the scope of protection of the utility model should be by
