Description

TECHNICAL FIELD

[0002] Motor suspension refers to suspending the motor and its related components (such as reducer, transmission, etc.) on the structure of a vehicle or other equipment through a specific device to realize the fixation and shock absorption of the motor. This design can effectively reduce the vibration and impact received by the motor during operation, thereby prolonging the service life of the motor and improving its performance. The design of the motor suspension system needs to consider various factors, including the weight, size, operating environment of the motor and the required shock absorption effect. Different application scenarios may have different design requirements. For example, in electric vehicles, the motor suspension system needs to be able to withstand high torque and frequent starting and stopping; while in industrial equipment, the motor suspension system may need to have higher durability and fatigue resistance. The motor suspension system is an important engineering technology, widely used in various mechanical equipment and vehicles to improve the stability and reliability of the system.

[0003] The existing motor has poor buffering effect after suspension installation is completed. Since the motor will produce vibration during operation, if there is no effective buffering structure, these vibrations will be directly transmitted to the vehicle body or other connecting components, which not only affects the comfort of the vehicle, but also may cause damage to other electronic devices and mechanical components. Long-term vibration and impact will cause fatigue damage to metal components, shorten the service life of parts, especially in electric vehicles, the vibration of the motor is more obvious, and the lack of buffering structure will accelerate the aging and damage of parts.
