Abstract

The utility model provides a connection mechanism between the bottom frame of a stainless steel rail passenger car and the side wall. The end surface of the main beam is provided with a U-shaped bottom frame side beam, on which a corrugated floor is laid, and the U-shaped bottom frame side beam is fixedly connected with the side wall lower side beam. A bracket is formed, and the side wall outer wall panels are fixed on the lower side beams of the side walls to realize the connection mechanism between the bottom frame and the side wall outer wall panels. The connection mechanism can realize the connection between the bottom frame and the end side wall of the stainless steel production vehicle, and can meet the national subway limit standard. Replace the carbon steel car body with the B-type stainless steel car body section structure that meets the national subway limit standard "CJJ96-2003". structure.

Description

Connection Mechanism of Underframe and Side Wall of Stainless Steel Rail Passenger Car

technical field

The utility model provides a connection mechanism between a bottom frame of a stainless steel rail passenger car and a side wall, which belongs to the technical field of vehicle body structures.

Background technique

Stainless steel cars have the advantages of light weight, good anti-corrosion performance, and low maintenance costs, and their market prospects are very broad. Compared with carbon steel vehicles, the corrosion resistance of stainless steel is 2 to 3 times that of carbon steel for vehicles using B-type stainless steel vehicle body section structure. Therefore, the service life of the vehicle is much higher than that of carbon steel vehicles, and the operation and maintenance costs are very low. However, due to the different materials of stainless steel and carbon steel, the body structure also needs to be greatly changed in the actual production process to adapt to the stainless steel body.

Contents of the invention

The utility model provides a connection mechanism between the bottom frame and the side wall of a stainless steel rail passenger car, which solves the problem that the original carbon steel body structure cannot adapt to the stainless steel body production.

The technical solution of the utility model is as follows: the end face of the main beam is provided with a U-shaped underframe side beam, on which a corrugated floor is laid, the U-shaped underframe side beam is fixedly connected with the lower side beam of the side wall to form a bracket, and the outer wall of the side wall The board is fixed on the side beam of the side wall to realize the connection mechanism between the bottom frame and the outer wall board of the side wall.

The positive effect of the utility model is that: the connection mechanism can realize the connection between the underframe and the side wall of the vehicle made of stainless steel, and can meet the national subway limit standard. The B-type stainless steel car that meets the national subway limit standard "CJJ96-2003" The body section structure replaces the carbon steel body structure.

Detailed ways

As shown in Figure 1, the utility model is composed of a corrugated floor 1, a side wall outer wall panel 2, a side wall lower beam 3, a chassis side beam 4, and a main beam 5 to form a connection mechanism between the chassis and the side wall, wherein the main beam 5 The end face of the U-shaped frame is provided with a U-shaped frame edge beam 4, and a corrugated floor 1 is laid on it. The U-shaped frame frame edge beam 4 is fixedly connected with the lower edge beam 3 of the side wall to form a bracket, and the outer wall panel 2 of the side wall is fixed on the lower side of the side wall. The connection mechanism between the bottom frame and the side wall outer wall panel is realized on the beam 3 .

Claims (1)
