Problems solved by technology

Second, the pumping phenomenon due to the suction of the fan wheel plus the deformation of this wheel causes the axial movement of the motor
[0005] The disadvantage of this case is the lack of standardization of the mount, which receives each type of motor
This large number of installations leads to control and logistics problems that manufacturers of ventilation and heating systems for motor vehicles want to reduce

Embodiment Construction

[0024] It should be noted that the accompanying drawings, which show the invention in a detailed manner to carry it out, can naturally be used, if necessary, to define the invention more clearly.

[0025] figure 1 A motor-blower assembly 1 is shown comprising a mount 2 housing an electric motor 3 . The motor-blower assembly also includes a fan wheel or turbine 4 . The fan wheel or turbine sucks air through the open face 5 and then discharges the air to the sides in a direction perpendicular to the air inlet direction through the open face 5 .

[0026] The turbine comprises a series of blades 6 connected together at their free ends by bands 7 . The blades originate from the peripheral edge of the bowl 8, which can be welded or perforated, for example. A hub 9 is arranged in the center of said bowl for mechanically connecting the turbine 4 to a shaft 10 forming part of the motor 3 .

[0027] An electric motor 3 drives a turbine 4 in rotation to circulate airflow within the v...

Abstract

The invention relates to a mounting 2 in which is accommodated an electric motor 3 having a shaft 10 extending along a longitudinal axis 13 , said motor 3 having a mass transverse to the longitudinal axis 13 and passing through a center of gravity 40 of the electric motor Balance line 22, said mounting 2 is connected to motor 3 via a plurality of decoupling means 20 distributed around the periphery of the motor, characterized in that the longitudinal position D2 of at least one decoupling means 20 relative to mounting 2 and the The dimension D3 of the decoupling device 20 along the longitudinal axis 13 is determined with respect to the mass balance line.

Description

technical field [0001] The invention relates to the field of mounting devices for electric motors of ventilation, heating and / or air-conditioning systems of motor vehicles. More specifically, the invention relates to a mounting device comprising means for decoupling the vibrations of the motor. Background technique [0002] In ventilation, heating and / or air conditioning systems in which the air circulated is propelled by a fan wheel which is rotated by a motor. The operation of the fan impeller and motor generates vibrations. The vibrations cause acoustic and vibrational disturbances (including imbalances) within the vehicle's passenger compartment. The vibrations are transmitted via the motor mount to the entire ventilation, heating and / or air conditioning system and create sound waves that disturb the comfort of the vehicle's occupants. [0003] To solve this problem, decoupling means are arranged between the motor and the motor mount. Said decoupling means are only e...
