Existing eight axle electric locomotive traction devices do not adopt single draw bar low level traction.
Summary of the invention
The utility model provides a kind of eight axle bogie of electric locomotive draw geares, adopt single draw bar directly to connect diaxon framework and car body, wheel track longitudinal traction and braking force are directly passed to car body, bogie structure is greatly simplified, and can realize good utilization of adhesion.
For achieving the above object, a kind of eight axle bogie of electric locomotive draw geares, comprise traction seat and draw bar; Described traction seat comprises pedestal, upper loading plate, lower loading plate and mandrel; Mandrel is located on lower loading plate; Pedestal comprises front side plate, rear quarter panel, left side board and right side board, and front side plate, rear quarter panel, left side board and right side board are connected to form framework, and the upper end of left side board is outwardly-bent, and right side board is outwardly-bent; Upper loading plate is connected to the upper end of framework, and the surrounding of upper loading plate is stretched out framework; Lower loading plate is connected to the lower end of framework, and the surrounding of lower loading plate is stretched out framework; Draw bar comprises the body of rod and is located at the adapter sleeve at body of rod two ends; The described body of rod comprises first body of rod, second body of rod and the 3rd body of rod, the first body of rod horizontal-extending, and second body of rod extends obliquely upward from first body of rod, and the 3rd body of rod is from the second body of rod horizontal-extending, and wherein an adapter sleeve is enclosed within on mandrel.
Said structure, because pedestal is hollow frame structure, therefore, has alleviated the weight of traction seat greatly.Due to left side board and the outwardly-bent extension of right side board, like this, after making loading plate be connected on pedestal, connect sectional area and increase, increased bending resistance anti-twisting property, the intensity of traction seat is high, has improved the weight capacity of traction seat.Owing to being provided with second body of rod, like this, first body of rod can, lower than second body of rod, therefore, reduce the height of draw bar one end and realize low level traction, to improve traction adhesion availability, and can avoid again draw bar to exceed gauge.
As improvement, between left side board and lower loading plate, be provided with left gusset, between right side board and lower loading plate, be provided with right web plate, to improve the intensity of traction seat, thereby further improve bearing value.
As improvement, mandrel is taper, can quick centring, draw gear is installed, and between mandrel and lower loading plate, be provided with Connection Block.
As specializing, the body of rod comprises header board, rear plate, top board and base plate, header board, rear plate, top board and the base plate formation hollow rod body that welds together.This structure lightweight, adopts the mode of welding to manufacture the body of rod, and easily manufactured, cost is low.
As improvement, adapter sleeve is provided with connecting bore, and a lateral edges of connecting bore is provided with the flange extending internally, and described flange is used for limiting upwards play of rubber arthrosis, realizes the location to rubber arthrosis.
As improvement, in connecting bore, be provided with spherical rubber joint.
