Description

A kind of cab apron device of rail vehicle

Technical field

This utility model belongs to rail vehicle technical field, specifically related to a kind of cab apron device of rail vehicle.

Background technology

Cab apron device is to realize that ground between two compartments couples the important component of insertion on rail vehicle.Current country's motor-car Quickly grow, except design speed per hour up to 350km/h standard EMUs in addition to, each carshop have also been devised speed per hour 160km/h, when Fast 200km/h etc. is applied to the low speed EMUs run between adjacent cities.Different vehicles proposes different to cab apron device It is required that, also just derive the cab apron device of different structure.

Current cab apron device, its structure type is mainly bridging type cab apron（Two pieces of overlap joints or three pieces of band linkages are taken Connect）, can only typically be used for specific vehicle, replaceability and the degree of modularity are relatively low；Its wear part is easily lost, and cost is high, property Can be unstable, easily there is abnormal sound.Also movement interference deformation between frequent generation part simultaneously.For the small curve serious mistake of EMUs The operating mode of position amount operation, existing cab apron device structure is difficult to, and there is the defect such as its structure and body end interference, to motor-car There is potential safety hazard in group and passenger.

In addition, being defined to the direction vocabulary being previously mentioned in this case, in track vehicular field, technical staff generally recognizes Fixed direction has three kinds：

It is vertical：Vertically perpendicular to the direction of rail level.

Longitudinal direction：Along the direction of track.

Laterally：Horizontal vertical is in the direction of track.

Utility model content

In view of the above-mentioned problems, the utility model aims to provide a kind of adaptation vehicle operation curve ability by force, wide adaptability, dimension Protect the cab apron device of convenient rail vehicle.

The utility model solve problem technical scheme be：A kind of cab apron device of rail vehicle, including with adjacent two car The rectangular frame of the car end connection in railway carriage or compartment, the framework includes crossbeam and longeron, is placed with successively along longitudinal direction and is connected across parallel longeron On tread beam, head and the tail two tread beams abutted respectively with crossbeam；

The tread beam two ends and the junction of longeron are hinged, tread beam can opposing side rails in the horizontal plane around pin joint turn It is dynamic；

The four points of connection of the rectangular frame entablature and longeron is hinged, and crossbeam and longeron can be relative in the horizontal plane Pin joint is rotated.

In such scheme, when occurring big shearing operating mode in vehicle operation, between adjacent compartment, whole framework is become by rectangle Into parallelogram, vehicle operation curve ability is adapted to strong.Moreover, after locomotive remodeling only tread beam number need to be increased according to size Or width is wide adaptability the need for being suitable for different automobile types.

Further, the transverse ends of the tread beam are respectively equipped with U-shaped opening, provided with cylinder gear at the top of longeron Pin；The cylinder backing pin is placed in U-shaped opening, and is abutted with U-shaped opening.

This kind of concrete structure causes tread beam in the horizontal plane to be rotated around backing pin.

Further, the tread beam includes aluminium tread beam and nylon tread beam, and two kinds of beams are i shaped cross section Beam；

The nylon tread depth of beam is equal to the height of aluminium tread web, aluminium tread beam and nylon tread beam alternating cloth Put, between the two neighboring aluminium tread web of nylon tread beam insertion in die cavity, the upper and lower surface point of nylon tread beam Wing plate inner surface not with aluminium tread beam is overlapped.

In above-mentioned further improved scheme, using I-shaped aluminium tread beam and nylon tread beam interlaced arrangement, it rubs Coefficient is small, reduces noise, and abrasion loss is small, and intensity is good.

Further, the variable angle scope of the crossbeam and longeron is [37 °, 143 °].Using I-shaped aluminium tread Beam and nylon tread beam interlock overlap joint, and slewing area increase is may be such that by reducing faying surface.

Further, the first guide holder and second that the framework also includes being connected with the car end in adjacent two compartment is oriented to Seat, the first tie-beam being across on the first guide holder, the second tie-beam being across on the second guide holder；

First tie-beam is hinged with wherein one crossbeam so that the plane of tread beam composition can be around the first tie-beam Axis is rotated；Second tie-beam is connected with another crossbeam by lock.

Said structure causes constituted tread side to be articulated structure, and side is pinned, and when safeguarding, unlocking can be opened and stepped on Face.Lockset can use the quick locking lockset with auto-lock function, can be locked using the square hole of standard.

It is preferred that, that one side away from tread beam on the first tie-beam and the second tie-beam has abutted leaf spring, institute State the face work that leaf spring is fixed on compartment.

Leaf spring is molded for spring steel pressing mold, and leaf spring is compressive state after installation, and it provides certain precommpression for framework Power, with the motion between compartment, leaf spring relaxation or further compression, it is ensured that cab apron device will not produce play when running.

It is preferred that, it is covered with wearing layer on first guide holder and the second guide holder.Wearing layer causes cab apron device to make It is noiseless with running during the life-span.

Remarkable result of the present utility model is：

1. cleverly having used the principle of parallelogram motion so that frame stroke amount is big, it is suitable between two vehicles greatly Misplace operating mode, adapts to vehicle operation curve ability stronger.

2. employing aluminium tread and nylon tread interlaced arrangement, its intensity is good, and replaceability is strong, and diversified forms can be coordinated to move Car group is used.

3. adapting to the change of car end spacing using the deformation of leaf spring, cab apron device will not produce play when running, completely The circuit operating condition of EMUs is met, the failure of interference, abnormal sound etc will not be produced.

4. using the structure similar to vertical hinged door, installing/dismounting is very convenient during working service.
