Abstract
A kind of Highs-speed motor train unit bogie single stage suspension and axle-box positioning device, single stage suspension adopts helical steel springs group to add the mode of vertical damper, below helical steel springs group, laminated spring is housed, helical steel springs group is built with pin, axle-box locating adopts pivoted arm axle-box locating, axle box is divided into pivoted arm and pivoted arm hoop two body, is pressed with location node, pivoted arm is equipped with safety catch in pivoted arm.Below steel spring group, laminated spring is housed, can plays good buffering, reduce the effect of vertical vibration, and helical steel springs group is connected with laminated spring, rear rigidity is less, is conducive to vehicle smoothness.In helical steel springs group built with pin, spring both can be prevented to be crushed to death, also can to have played a supporting role in emergency situations.Adopt pivoted arm axle-box locating, for the ease of wheel to replacing, pivoted arm is equipped with safety catch, adds safety.Under vehicle dead weight, spring installation rigidity is less, and natural bow is large, makes the car body natural frequency of vibration low, favourable to vehicle smoothness, can meet the performance requriements of EMU.
Description
Technical field
The utility model relates to Highs-speed motor train unit bogie single stage suspension and axle-box positioning device structure.
Background technology
Existing subway, light rail vehicle bogie truck many employings rubber spring type single stage suspension and duplex pull rod locate mode, this structure adopts rubber spring between axle box and framework, two, each axle box, is installed on axle box both sides respectively, utilizes the elastic deformation of rubber to realize buffering and vibration damping.Rubber spring vertical stiffness is higher, and due under vehicle dead weight, spring installation rigidity is large, and natural bow is little, makes the car body natural frequency of vibration high, unfavorable to vehicle smoothness, is more suitable for slow-moving vehicle, can not meets the requirement of EMU.And duplex pull rod location structure parts are more, complex structure, each link goes wrong will affect the positioning performance of single stage suspension.Therefore, design a kind of can meet EMU use require bogie primary-suspension and axle-box positioning device be very necessary.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of single stage suspension and the axle-box positioning device that meet Highs-speed motor train unit bogie running stability.
For solving the problems of the technologies described above, the utility model provides a kind of Highs-speed motor train unit bogie single stage suspension and axle-box positioning device, it is characterized in that: comprise helical steel springs group, laminated spring, pin, vertical damper, pivoted arm axle box forms, location node, safety catch, single stage suspension adopts helical steel springs group to add the mode of vertical damper, below helical steel springs group, laminated spring is housed, helical steel springs group is built with pin, axle-box locating adopts pivoted arm axle-box locating, axle box is divided into pivoted arm and pivoted arm hoop two body, location node is pressed with in pivoted arm, pivoted arm is equipped with safety catch.
The utility model single stage suspension adopts helical steel springs group to add the mode of vertical damper, below steel spring group, laminated spring is housed, good buffering can be played, reduce the effect of vertical vibration, and helical steel springs group is connected with laminated spring, rear rigidity is less, is conducive to vehicle smoothness.In helical steel springs group built with pin, spring both can be prevented to be crushed to death, also can to have played a supporting role in emergency situations.Adopt pivoted arm axle-box locating, for the ease of wheel to replacing, axle box is divided into pivoted arm and pivoted arm hoop two body, is pressed with location node, pivoted arm is equipped with safety catch, add safety in pivoted arm.Under vehicle dead weight, spring installation rigidity is less, and natural bow is large, makes the car body natural frequency of vibration low, favourable to vehicle smoothness, can meet the performance requriements of EMU.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing of A in Fig. 1.
Detailed description of the invention
See figures.1.and.2, the utility model comprises helical steel springs group 6, laminated spring 5, pin 7, vertical damper 8, pivoted arm axle box composition, location node 3, safety catch 4, single stage suspension adopts helical steel springs group to add the mode of vertical damper, helical steel springs group 6 is equipped with laminated spring 5 below, good buffering can be played, reduce the effect of vertical vibration, and steel spring group is connected with laminated spring, rear rigidity is less, is conducive to vehicle smoothness.Helical steel springs group 6, built with pin 7, both can prevent spring to be crushed to death, also can play a supporting role in emergency situations.Axle-box locating adopts pivoted arm axle-box locating, and axle box is divided into pivoted arm 1 and pivoted arm hoop 2 liang of bodies, is pressed with location node 3, pivoted arm 1 is equipped with safety catch 4 in pivoted arm 1, is convenient to wheel to replacing, adds safety.Vertical damper 8 is arranged between pivoted arm 1 and framework.
