When the electric automobile encounters severe rainfall weather, the driving motor on the automobile has the possibility of wading or the motor is directly used for underwater operation equipment; however, when the motor starts to work, air in a shell cavity of the motor can generate high temperature due to the fact that the magnetic induction coil passes through current, the air in the shell cavity of the motor is heated, positive pressure air pressure is formed due to the effect of expansion with heat and contraction with cold, and high-pressure air can be extruded out of the motor shell through the water seal piece and the oil seal piece at the power output shaft of the motor.

When the driving motor stops working, because the motor is in an underwater environment, low-temperature water can rapidly cool hot air in the cavity of the motor shell, so that the hot air is rapidly converged and contracted in the cavity of the motor shell to form negative pressure difference; at the moment, water outside the motor shell cavity is easy to permeate into the motor cavity gradually through a gap between a water seal part and an oil seal part of the power output shaft due to the negative pressure difference of air in the motor shell cavity, so that motor faults are caused. And the water seeping into the motor can firstly contact with the bearing at the shaft extension end, the bearing is damaged due to the deterioration or failure of the grease inside the bearing and the bearing parts after the bearing meets the water, and the operation of the motor is seriously influenced due to the damage of the bearing.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention discloses a wading type double-power synchronous driving motor, which can balance the air pressure in a double-motor shell through an arranged air pressure adjusting device, and effectively avoids the damage to the motor caused by the permeation of external water into the double-motor shell.

The embodiment discloses a wading type double-power synchronous driving motor which comprises a double-motor integrated mechanism 1 and an air pressure adjusting device 2 arranged on one side of the double-motor integrated mechanism 1; the double-motor integrated mechanism 1 comprises a double-motor shell 11, and a main driving motor 12 and an auxiliary driving motor 13 which are positioned in the double-motor shell 11; the main driving motor 12 and the auxiliary driving motor 13 are coaxially arranged and share the same motor shaft 14; because the main driving motor 12 and the auxiliary driving motor 13 work coaxially, the synchronous output of the same rotating speed and power by power is ensured.

The air pressure adjusting device 2 comprises an adjusting device shell 21 and an air bag 22 positioned in the adjusting device shell 21; the air bag 22 is communicated with the shell cavity of the double-motor shell 11 through an air pipe 23, one end of the air pipe 23 is communicated with the air bag 22, and the other end of the air pipe 23 penetrates through the adjusting device shell 21 and extends into the shell cavity of the double-motor shell 11.

In order to further optimize the above technical solution, the adjusting device housing 21 is located at one side of the dual-motor housing 11 and is designed as an integral part with the dual-motor housing 11.

In order to further optimize the above technical solution, motor shaft holes are respectively arranged on end covers at two sides of the dual-motor shell 11, and two ends of the motor shaft 14 respectively penetrate through the corresponding motor shaft holes and extend out of the dual-motor shell 11.

In order to further optimize the technical scheme, a water seal piece and an oil seal piece are arranged on the motor shaft hole.

In order to further optimize the above technical solution, a filter screen is disposed at one end of the air tube 23 extending into the cavity of the dual-motor housing 11.

In order to further optimize the above solution, the bladder 22 is a rubber bladder 22.

The working principle is as follows:

when the dual-motor integrated mechanism 1 is started, the air in the cavity of the dual-motor shell 11 can generate high temperature due to the current passing through the magnetic induction coil, so that the air in the cavity of the dual-motor shell 11 is heated, and the air pressure in the dual-motor shell 11 is increased due to expansion and contraction of the air to form positive pressure.

The positive pressure can fill part of the gas into the air bag 22 of the air pressure adjusting device 2 through the air pipe 23, so that the air bag 22 is stretched, and the gas is stored, thereby balancing the pressure in the cavity of the dual-motor shell 11.

When the double-motor integrated mechanism 1 stops working, because the whole device is in an underwater environment, low-temperature water can rapidly cool hot air in the cavity of the double-motor shell 11, so that the hot air is rapidly converged and contracted to form negative pressure difference in the double-motor shell 11; at this time, the gas in the airbag 22 enters the dual-motor case 11 through the gas tube 23, and the airbag 22 contracts while balancing the negative pressure. At the same time, since the airbag 22 is placed in the regulator housing 21, effective protection is achieved.
