Abstract
The utility model provides a suspension linkage for the single arbor wheel pairs, which comprises a axle box arranged on the end portion of the wheel shaft and a vertical absorber connected between the axle box and a frame, and is characterized in that the axle box disposed on the end portion of the wheel shaft is fixed on a mounting rack connected with the frame through a cone spring, an anti-snakelike absorber is provided between the axle box and a straight pillar connected with the frame. The suspension linkage takes the place of a complex structure comprising a cylinder spiral spring, an inner and an outer lifting ring and an axle box positioning device. Through reasonable match the three-dimensional hardness parellel hydraulic shock absorber of the cone rubber spring can efficiently absorb the vibrations during the operation of vehicles, eliminate the high-frequency vibrations, improve the vibration properties and reduce the noise, further the anti-snakelike absorber can increase the vehicle stability of the snakelike movement and the passed nature of the curved line, thereby increasing the operation stationarity of the whole machine, and the utility model has the advantages of simple structure, reasonable arrangement, good vibration-damping property and convenient installation and maintenance or the like.
Description
Technical field
The utility model provides a kind of single shaft wheel to suspension, and especially a kind of railway single shaft rolling stock wheel belongs to design of railway single shaft rolling stock and manufacturing technology field to suspension.
Background technology
The single shaft wheel is the running part of single shaft rolling stock to suspension, its effect is to bear load and the motive power that car body transmits, take turns passing to rail by axletree, thereby guide whole locomotive to move along rail, guarantee voluntarily or connection hang under the running state all can be flexibly, safely along railway operation with pass through railway curve.Existing single shaft wheel to suspension mainly comprise cylindrically coiled spring, inside and outside suspension ring, vertical damper, wheel to axle box and registration device thereof, wheel to and foundation brake rigging.There is following deficiency in this structure: 1, complex structure, and axle-box positioning device easily wears away; 2, laterally, longitudinal register rigidity is big, curving performance is poor.Thereby have a strong impact on the riding quality of this single shaft rolling stock.Therefore, be necessary prior art is improved.
Summary of the invention
For overcome existing single shaft wheel to complex structure, the axle-box positioning device that suspension exists easily wear away, laterally, deficiency such as big, the curving performance difference of longitudinal register rigidity, it is a kind of simple and reasonable for structure that the utility model provides, and the single shaft that is used on the single shaft rolling stock that cushioning performance is good is taken turns suspension gear.
The utility model is realized by following technical proposal: a kind of single shaft wheel is to suspension gear, comprise the axle box that is arranged on the wheel shaft end, be connected the vertical shock absorber between axle box and the vehicle frame, the axle box that it is characterized in that the wheel shaft end is fixed on the erecting frame connected to ground by cone-shaped spring, axle box and be connected and be provided with anti-snakelike shock absorber between the right cylinder on the vehicle frame.
Described cone-shaped spring is separately positioned on the axle box both sides, and the upper end of cone-shaped spring links to each other with erecting frame by butt flange, so that when bearing deadlight load and motive power, the elasticity by spring cushions the shock and vibration from car body.
Described vertical shock absorber is installed on the axle box between two cone-shaped springs, and its upper end is installed on the vehicle frame, so that further damped vibration, the potential energy of avoiding spring to be subjected to discharge after the additional compression causes the vibration on spring top.
Described anti-snakelike shock absorber one end is fixed on the right cylinder connected to ground, the other end is fixed on the journal box lid, can make vehicle serpentine locomotion stability and curving performance all obtain the Resistance Value that suits simultaneously by this shock absorber, to improve the running stability of complete machine.
The utility model compared with prior art has following advantage and effect: adopt such scheme, promptly replace the labyrinth be made up of cylindrically coiled spring, inside and outside suspension ring, axle-box positioning device with conical rubber spring vertical bumper of parallel connection and horizontal damper.Three-way rigidity by rational Match conical rubber spring liquid damper in parallel can effectively absorb the vibration in the vehicle operating, eliminate high-frequency vibration, improve vibration performance, reduce noise, improve vehicle serpentine locomotion stability and curve negotiating by anti-snakelike bumper again, thereby improve the running stability of complete machine, the utility model also has simple in structure, characteristics such as rationally distributed, cushioning performance is good, and installation and maintenance are convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A section-drawing of Fig. 1.
Be positioned at wheel to two vertical erecting frames 1 are installed on the car body curb girder of 10 tops, the lower end of erecting frame 1 links to each other with conical rubber spring 3 by butt flange, the lower end of conical rubber spring 3 is installed in axle box 4 both sides, and be fixed on the axle box 4 by locking piece 9, axle box 4 passes through its interior bearing installation in wheel shaft 11 ends, be positioned at two conical rubber springs, 3 middle axle boxes 4 and be provided with vertical liquid damper 2, the upper end of this shock absorber be installed in vehicle frame on 2 bearings that link to each other 7, thereby constitute one group of shock absorption device, be connected with horizontally disposed anti-snakelike hydraulic damper 5 on the journal box lid 8, the other end of this shock absorber is installed on the right cylinder 6, the upper end of right cylinder 6 is fixed on the vehicle frame 12, thereby constitute another group shock absorption device, so that bear car body weight, effectively absorb the vibration in the vehicle operating, eliminate high-frequency vibration, improve vibration performance, reduce noise; Improve vehicle serpentine locomotion stability and curve negotiating by vertical liquid damper is installed, improve the running stability of complete machine.
