One end of described axle box is connected with the radius arm of described framework by location node, and the top of axle box is equipped with spring assembly and rubber pad and support and connection below framework.
Adopt spring assembly, and location node is applied in being connected of axle box and framework, both can play the effect of location, can realize the rigidity Design that bogie truck is vertical, horizontal and rotate by location node in addition, spring assembly and rubber pad are used the vertical stiffness that then can improve bogie truck, and buffering is from the right vibration of wheel.
At described axle box, and vertical oil-pressure damper 16 is installed between the framework above the axle box, so that the dynamic performance of bogie truck to be provided better.
Two air bellows are installed above described framework, and the top of air bellow directly is connected with the underframe of car body.
Connect the two ends of a torsion bar between two mount pads of car body, the middle part of this torsion bar is positioned at the below of framework and fixes by the torsion bar permanent seat.
One end of the anti-oil-pressure damper that crawls is installed in the side of framework, and the other end is installed on the anti-damper base that crawls; The anti-damper base that crawls is installed in the below of car body underframe by bolt, locating dowel pin.Just, use the anti-oil-pressure damper that crawls to be connected between framework and the car body, reduce the vehicle effect of hunting in orbit to play.
One end of lateral oil pressure damper is connected in framework, and other end connection is anti-crawls damper base to be connected in car body indirectly.Then can reduce the lateral vibration of bogie truck and car body, improve dynamic performance.
Horizontal backstop is installed above described framework, and laterally backstop is oppositely arranged with the buting iron that extends downwards from the car body underframe.
Described horizontal backstop and buting iron are set to two covers, and are provided with axisymmetrically along the bogie truck longitudinal centerline.
Laterally can leave suitable gap between backstop and the buting iron, when the cross motion between bogie truck and the car body is big, will touch, can avoid this type of excessive cross travel effectively by horizontal backstop and buting iron.
Content to sum up, described single motor driving steering frame has the following advantages:
1, realizes a kind of novel steering frame that adopts single motor-driven, vertically is provided with, can be applicable to narrow gage vehicle especially.
2, reduce bogie truck whole height and load-carrying effectively, can promote to improve the running velocity of narrow gage vehicle.
