Embodiment Construction

[0021] Install the waterproof wave-opening self-ventilating main generator of the internal combustion motor vehicle under the car, including a base 4, on which a non-drive end cover 2 with a first air inlet 18 is opened; Air duct 5, the bottom of air guiding tube 5 is sealed, and the opening at the top is upward. On the side opposite to the outer end face of the non-driving end cover 2 of the air guiding tube 5, there is a first air inlet opening on the non-driving end cover 2. The air intake window 6 facing the 18 positions. In this way, by setting the air guide tube, the axial air intake is transferred to the radial air intake above the motor to reduce the entry of water waves. Further, a first drainage hole 7 is opened at the bottom of the air guide tube 5 to discharge a small amount of accumulated water splashed into the air guide tube. The first air inlet 18 on the non-drive end cover 2 is opened above the horizontal center line of the non-drive end cover 2, and the lowe...

Abstract

The invention relates to a generator, in particular to a water-wave-proof open-type self-ventilation main generator installed under a vehicle and used for an internal combustion motor car. The problemthat water waves easily enter a motor through an air inlet and an air outlet of an open type self-ventilation main generator on a power dispersion type internal combustion motor car is solved. An airduct is fixed to the outer end face of a non-transmission end cover of the main generator, the bottom of the air duct is sealed, an opening in the top of the air duct is upward, and an air inlet window right opposite to a first air inlet in the non-transmission end cover is formed in the side face, opposite to the outer end face of the non-transmission end cover, of the air duct. A second air inlet is formed in the end, close to the non-transmission end cover, of the top of the machine base and covered with a machine base air inlet cylinder. A water baffle is fixed to the lower portion of theair outlet in the machine base so that water waves can be prevented from splashing into the stator through the air outlet. According to the invention, the main generator with the open type self-ventilation structure meets the requirement of water wave prevention under the vehicle, so that the main generator can be pushed to move on the power dispersion type internal combustion motor car.

Description

technical field [0001] The invention relates to a generator, in particular to a waterproof wave-opening self-ventilating main generator installed under the train for an internal combustion train. Background technique [0002] In recent years, with the rise of diesel trains, the main generator, which is the core component of diesel trains, has ushered in a good opportunity for development. Diesel trains are divided into power centralized and power decentralized. The power centralized type has a special drag locomotive. The diesel engine and main generator are installed on the upper part of the drag locomotive frame. The locomotive is used as a power car and does not carry passengers. There is no dedicated traction locomotive for the power-distributed diesel train, and the diesel engine and the main generator are scattered under the frame of the passenger car, which does not occupy the interior space of the passenger car. The power-distributed internal-combustion train saves ...
