Abstract
A railway vehicle bogie inner side wheel disc braking composite suspending seat comprises a suspending seat body, wherein a welding port suitable for being welded with a bogie side beam is arranged in the outer side of the suspending seat body, an installation port used for installation of a braking device is arranged in the inner side of the suspending seat body, and a suspending port used for suspension is arranged in the upper portion of the suspending seat body. By means of optimum structural design, the braking composite suspending seat meets installation requirements of the inner side braking device, and is provided with a bogie overall suspending port. By means of finite element calculation, the braking composite suspending seat meets requirements for static strength and fatigue strength. The railway vehicle bogie inner side wheel disc braking composite suspending seat is ingenious in conception, simple in structure, convenient to use, and good in effect. The railway vehicle bogie inner side wheel disc braking composite suspending seat is widely popularized in the industry, and has a good market prospect.
Description
Technical field
The utility model relates to the compound flap seat of the inboard Multiple disc brake of a kind of rail vehicle truck, belongs to especially the rail vehicle truck technical field.
Background technology
Framework is the installation basis of parts on the bogie truck, is that supporting body also is force transfer body simultaneously, and the conceptual design of bogie truck mainly is the design of framework structure.EMU and city railway vehicle steering structure shelf structure all are welded structure usually at present, become curb girder and crossbeam by the sheet material assembly welding, the foundry goods such as welding braking flap seat, motor cabinet, positioning seat on curb girder, the crossbeam.
Present domestic city rail vehicle motor car bogie brake equipment mode mainly contains tread brake and Multiple disc brake, tread brake is divided into again built-in and external, and Multiple disc brake is owing to being subjected to the tractor equipment space constraint such as motor and gear case, usually adopt the external Multiple disc brake, this mode brake equipment is installed in the curb girder end, be subject to vibratory impulse larger, and whole bogie structure is compact not.In order to satisfy the requirement of the inboard Multiple disc brake of city rail vehicle, need a kind of braking flap seat of customized design.
Summary of the invention
Technical problem to be solved in the utility model is, overcome the above-mentioned shortcoming of prior art, provide the inboard Multiple disc brake of a kind of rail vehicle truck compound flap seat, both can be used for installing inboard disc brake, the whole lifting interface of bogie truck is a kind of compound flap seat again.
In order to solve above technical matters, the compound flap seat of the inboard Multiple disc brake of the rail vehicle truck that the utility model provides, comprise the flap seat body, it is characterized in that: the outside of described flap seat body has the welding junction that is suitable for the bogie truck side beam welding, the inboard of flap seat body has for the mounting interface that brake equipment is installed, and the top of flap seat body has the lifting interface for lifting.
Further, described mounting interface comprises four mounting holes that cooperate with brake equipment, is used for hanging the installation brake equipment.
Further, described lifting interface is circular hole.
By Optimal Structure Designing, the utility model is braked the installation requirement that compound flap seat satisfies inboard brake equipment, and has the whole lifting interface of bogie truck.By FEM (finite element) calculation, brake compound flap seat and satisfy static strength and strength at repeated alternation requirement.
The utility model ingenious conception, simple in structure, easy to use, effective.Be well received in the field of business, have good market outlook.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is that the utility model is braked the oblique downwards angle of visibility structural representation of compound flap seat.
Fig. 2 is that the utility model is braked the oblique upward angle of visibility structural representation of compound flap seat.
The specific embodiment
The compound flap seat of the inboard Multiple disc brake of the rail vehicle truck of the present embodiment, as shown in Figure 1 and Figure 2, comprise flap seat body 1, the outside of flap seat body 1 has the welding junction 2 that is suitable for the bogie truck side beam welding, the inboard of flap seat body 1 has for the mounting interface 3 that brake equipment is installed, and the top of flap seat body 1 has the lifting interface 4 for lifting.Mounting interface 3 comprises four mounting holes that cooperate with brake equipment, is used for hanging the installation brake equipment; Lifting interface 4 is circular hole.
For whether the composite brakig flap seat of verifying design satisfies static strength and strength at repeated alternation requirement, the composite brakig flap seat that designs is carried out static strength and punishing stress test.Experimental evidence UIC615-4 standard is at the static strength of framework being carried out extraordinary operating mode and 1,000 ten thousand punishing stress tests, and the composite brakig flap seat carried out separately punishing stress test 8,000,000 times, and after test, carry out non-destructive test, do not find crackle and other defect, whole test is finished in French AEF laboratory.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
