Embodiment Construction
[0028] Such as figure 1 , figure 2 As shown, the axle box rotary arm system includes a series of positioning rubber piles 1, a series of traction rubber nodes 2, a series of traction arms 3, an axle box rotary arm 4, and an axle box 5. There are two arm grooves on both sides (front and rear) of the pivoting arm of the axle box; there are two primary positioning rubber stacks, and the two primary positioning rubber stacks are respectively connected to both sides of the pivoting arm of the axle box. The end plates of the positioning rubber stack are snapped into the pivot arm grooves on both sides of the axle box pivot arm respectively.
[0029] Such as image 3 As shown, a series of positioning rubber stacks are mainly formed by vulcanizing end plate one 6 with threaded holes, partition plate 7, end plate two 9 with through holes and rubber 8. End plate 2 and end plate 1 are respectively located at the top and bottom of the first series of positioning rubber piles; the midd...

The invention discloses an axle box rotating arm system, a single-stage positioning rubber stack and a mounting method thereof. The single-stage positioning rubber stack is formed by an end plate 1 with a threaded hole, a partition plate, an end plate 2 with a through hole and rubber single-stage, wherein a taper mounting hole is arranged in the middle of the single-stage positioning rubber stack.The axle box rotary arm system comprises an axle box, an axle box rotary arm, a single-stage traction arm, a single-stage traction rubber node, and the single-stage positioning rubber stack. The single-stage positioning rubber stack is arranged at the inner side of a bogie arm with a screw; and then the single-stage positioning rubber stack is pre-compressed by screwing nuts on the outside of thebogie arm; after preloading to the prescribed size, the frame and axle box rotary arm are place well; the single-stage positioning rubber stack is mounted in place; and then the nut and the screw areremoved. The invention meets the lateral positioning and use requirements of a novel axle box rotating arm, can ensure that the pbaruct process to achieve the needs and meet the installation of screwthroughput requirements, and can meet the requirement that the rubber stack should be pre-compressed before installation in the axial direction.
Description
technical field [0001] The invention relates to the technical field of vehicle vibration reduction. Background technique [0002] At present, the new type of bogie that appears is a type of bogie with international competitiveness, high energy efficiency, low noise, and high adaptability for a new generation of urban rail trains. A series of positioning systems for rubber piles are used for positioning. This positioning system has the characteristics of a wide range of longitudinal stiffness and transverse stiffness ratio. This kind of axle box rotating arm system (namely: the new type rotating arm structure) requires the system to have small lateral stiffness and high longitudinal stiffness. Next, the non-linear relationship of positioning rubber stacks to mounting axial stiffness is achieved. The new type of bogie requires positioning of the rubber stack for lateral preloading installation, which is different from the previous rubber stack being installed in a free state...
