Description

A vehicle-mounted universal chassis

technical field

The utility model relates to a chassis, in particular to a vehicle-mounted universal chassis.

Background technique

On-board equipment is an important equipment to control the operation of trains. Its reliability, stability and safety are important guarantees for the safe operation of trains.

Due to the limitation of the installation space of the train equipment, the dimensions of the vehicle-mounted equipment are relatively small, and the installation space of the vehicle-mounted equipment is relatively small, but the power of the vehicle-mounted equipment is relatively large, and heat dissipation and waterproofing are technical difficulties. Waterproof performance will affect the reliability, stability, safety and service life of vehicle equipment.
