Problems solved by technology

Since the height of the corrugated floor is 30 mm, it is not easy to control. When assembling the corrugated floor, it is necessary to adjust and repair the end of the corrugated floor and insert it under the upper cover of the corbel. This requires high assembly accuracy and increases the workload of adjustment and repair.

Abstract

A control car chassis, said control car comprising an end wall, and a cab; the end wall and the cab are respectively arranged at a front end and a rear end of said chassis; a towing beam (1) is fixed on a bottom surface of both the front end and the rear end of the chassis; the towing beam (1) is shaped by bending a steel plate. The towing beam uses a steel plate bending shaping structure to replace an existing tailor welded structure, thus having a better processing moldability, reducing an amount for welding and improving the bearing capability of the towing beam. Further comprised is a control car comprising the chassis.

Description

technical field [0001] The present application relates to rail transit technology, in particular, to a control vehicle chassis and a control vehicle. Background technique [0002] The 25-type passenger car has been in operation for many years, and many technologies have been gradually updated. Many new structures and design concepts have been applied to the design, which greatly improves the stability and comfort of the vehicle. [0003] The underframe of the car body is the key load-bearing part of the steel structure of the car body, which plays a vital role in the safe operation of the vehicle. It is necessary to take into account the requirements of light weight under the premise of ensuring reliable strength during design. The existing underframe design of the car body is as follows: figure 1 As shown, in order to meet the installation needs of large components such as the battery box and brake cylinder under the car, the chassis of the car body is designed with hangers...
