Abstract

The utility model discloses a cab shell for a high-speed railway vehicle. A brand new shell structure made of aluminum sections and a technology for processing the shell structure are realized, and all parts of the shell are made of stretch bending sections, so that streamline modeling required in the high-speed running process of the vehicle can be formed, and the processed shell and a vehicle body can be integrated optimally. The cab shell comprises skin and a framework which are welded on the vehicle body, wherein the skin comprises vehicle roof skin, side wall skin, a vehicle roof module and a side wall module. The parts of the skin and the framework are made of stretch bending sections which are formed by processing at one time; the vehicle roof skin, the side wall skin, the side wall module and the framework are connected through full-permeation assembling and welding to form the whole frame of the cab shell; and the whole vehicle roof module is adhered to the vehicle body. The shell which is formed by welding the skin made of the stretch bending sections and the framework has the perfect installed streamline modeling, can meet the requirement of aerodynamics to provide external strong-force support, and can effectively transfer various external impact forces.

Description

High-speed track vehicle driver's cab shell

Technical field

The utility model is that a kind of driver's cab containment structure that is applied to the high-speed track vehicle improves, and belongs to mechanical manufacturing field.

Background technology

The speed per hour of going of existing guideway vehicle reached 300 kilometers and more than, require to strengthen for car body surface profile, structure Design based on high-speed cruising thereupon.

The lifting of escort vehicle speed has proposed harsh requirement to vehicle front driver's cab shell at aspects such as aerodynamic appearance, high strength, lightweight, withstanding corrosion and air-tightness.Existing traditional passenger car body such as carbon steel and bar section of stainless steel are difficult to synthetically reach above-mentioned design standard on structure and profile; Driver's cab shell like steel structure of car body is generally the GRP type; Aspect brute force support and the transmission foreign impacts power many defectives are being arranged still; Be difficult to really satisfy the requirement of going of hot-short, there is certain defective in safety performance.

In view of this, the special present patent application that proposes.

The utility model content

The described high-speed track vehicle of the utility model driver's cab shell; Its purpose is to solve the problem of above-mentioned prior art existence and realizes a kind of brand new aluminium section bar containment structure and processing technology thereof; The whole parts that constitute shell all adopt the stretch bending section bar; Satisfy the streamline moulding that vehicle requires with formation in running at high speed, the processing rear casing can more optimally combine together with car body.

Another design goal is; Shell is on the basis that guarantees aerodynamic appearance; Can realize powerful the support and transmit various foreign impacts power well, thereby possess enough air-tightness and requirement of strength, in the hope of in high-speed cruising, protecting the safety of driver and car load.

For realizing above-mentioned design goal, described high-speed track vehicle driver's cab shell mainly includes the covering and the skeleton that are welded in car body.Wherein, covering includes roof covering, side wall covering, roof module and side wall module.

The difference with the prior art part is, constitutes the parts of said covering and skeleton, is the stretch bending section bar of time processing moulding;

Between roof covering, side wall covering, side wall module and the skeleton, be connected to driver's cab shell general frame through full infiltration assembly welding;

Roof module integrally is adhered to car body.

Like above-mentioned basic scheme; Covering, skeleton and car body have constituted the vehicle monocoque structure; And the whole parts that constitute the driver's cab shell all adopt the stretch bending section bar, and the stretch bending section bar has the streamline profile of processing in advance, in the actual installation process, can reduce adjusting and welding job amount significantly.

With the shell that the covering and the skeleton of stretch bending section bar is welded, have the perfect streamline moulding after the installation, can satisfy the aerodynamics requirement and outside powerful the support is provided, and can transmit various foreign impacts power effectively.

Hang in for ease of the integral body of subsequent installation in driver's cab internal unit and module, the further innovative approach that can take is, the support beam of a stretch bending section bar is set in the bottom of said roof module, and support beam is installed on the roof riveted girder that constitutes skeleton through rivet.

Roof module can reserve enough spaces that hangs in for follow-up in inner equipment and the module that big volume is installed of driver's cab.The roof riveted girder both can play the carrying effect, was convenient to follow-up equipment and module again and installed, plays when safeguarding the support that hangs in and hang out.

Content to sum up, the utility model high-speed track vehicle driver's cab shell has the following advantages:

1, realize a kind of brand new aluminium section bar containment structure and processing technology thereof, can satisfy the streamline moulding of running at high speed and requiring, working accuracy and production efficiency are higher.

2, on the basis that guarantees aerodynamic appearance, can realize the brute force support and transmit various foreign impacts power well, thereby possess enough air-tightness and requirement of strength, can protect the safety of driver and car load effectively.
