Abstract
The utility model relates to an elasticity side bearing especially relates to a long stroke elasticity side bearing that railway freight car vehicle was used. An object of the utility model is to provide a modified elasticity side bearing, on the basis of keeping the elasticity side bearing advantage of standard stroke normal contact, improve the bend trafficability characteristic of vehicle. The utility model comprises an upper body, a lower body and a rubber layer, wherein the included angle between the rubber layer side extension line and the horizontal plane of the bottom of the side bearing is 90-170 degrees, the rubber layer is vulcanized with the upper body and the lower body into a whole, and the vertical distance between the lower end surface of the upper body and the horizontal plane of the bottom of the side bearing is 20-35 mm. The utility model discloses mainly use as railway freight car vehicle's elasticity side bearing.
Description
Technical field
The utility model relates to a kind of elastic side bearing, relates in particular to for motor vehicle long travel elastic side bearing of a kind of rail freight.
Background technology
Chinese patent 02224263.5 discloses a kind of rail freight vehicle elastic side bearing, belongs to the structure member of bogies for railway vehicles.It is made up of upper body, lower body, rubber layer, it is characterized in that angle is 90-170 ° between described rubber layer side extended line and the side bearing bottom water plane, rubber layer and described upper body, lower body vulcanize in aggregates, and angle and rubber layer hardness can be adjusted with the car load size.
Above-mentioned elastic side bearing can be referred to as standard stroke The Constant-Contact Resilient Side Bearings, the traveled distance that is this type of elastic side bearing is less, that is to say, car body is with respect to the vertical deviation space of bogie side frame less (being generally 5-6mm), therefore, when vehicle passed through bend, side bearing was in the state (gap is zero) that is crushed to death relatively, to cause vehicle not pass through at a high speed, influence the riding quality of vehicle.
Summary of the invention
The purpose of this utility model is to provide a kind of improved elastic side bearing, on the basis of retention criteria stroke The Constant-Contact Resilient Side Bearings advantage, improves the bend through performance of vehicle.
Technical solution of the present utility model is on the basis that keeps original side bearing technical parameter, increases the stroke of The Constant-Contact Resilient Side Bearings, increases the vertical deviation space of car body with respect to bogie side frame.
The utility model comprises upper body, lower body, rubber layer, angle 11 between the side extended line of described rubber layer 2 and the side bearing bottom water plane is 90-170 °, rubber layer 2 and upper body 3, lower body 1 vulcanize in aggregates, it is characterized in that the lower surface 9 of upper body 3 and the vertical distance between the side bearing bottom water plane 10 are 20-35mm.
The utility model has the advantages that the overall performance that can improve vehicle, when being in particular in vehicle, have good vertical load harmony and balance at a high speed by bend.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Among the figure: 1-side bearing lower body, the 2-rubber layer, 3-side bearing upper body, 4-side bearing wear plate, 5-car body, the 6-wedge, 7-side bearing box, 8-bogie truck, the lower surface of 9-side bearing upper body, vertical distance between 10-lower surface and the side bearing bottom water plane, the angle between 11-rubber layer side extended line and side bearing bottom water plane.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises upper body, lower body, rubber layer, angle 11 between described rubber layer 2 side extended lines and the side bearing bottom water plane is 90-170 °, rubber layer 2 and upper body 3, lower body 1 vulcanize in aggregates, it is characterized in that the lower surface 9 of upper body 3 and the vertical distance between the side bearing bottom water plane 10 are 20-35mm.Its concrete implementation step is: earlier with upper body 3, lower body 1 places in the mould, injecting rubber then vulcanizes, make the rubber of injection form rubber layer 2, and with upper body 3, lower body 1 forms an integral body, and the angle 11 between the side extended line of rubber layer 2 and the side bearing bottom water plane can be adjusted according to the size of car load, angle 11 can be adjusted between 90-170 °, for example, when car load is 2 ton hours, angle 11 is 101 °, according to customer requirements, the vertical distance 10 between the lower surface 9 of upper body 3 and the side bearing bottom water plane for example can be designed and manufactured into: 20mm, 30mm or 35mm (when side bearing is free state).
