Front suspension assembly for powertrain

Abstract

The invention provides a front suspension assembly for a power assembly, belonging to the field of vehicles. The front suspension assembly comprises a suspension bracket and an inner tube component. The suspension bracket can be fixedly connected with an auxiliary frame, the suspension bracket comprises a first bracket and a second bracket, and an accommodation space is formed between the first bracket and the second bracket; the inner tube component comprises an inner tube and a rubber mainspring, the rubber mainspring and the inner tube are vulcanized into an integrated structure, the inner tube component is arranged in the accommodation space and can move freely relative to the accommodation space, and through the matching of the inner tube component and the suspension bracket, the front suspension assembly is not stressed in the process that an engine is fully static or the engine produces incentives. By adopting the front suspension assembly for the power assembly, the front suspension assembly is not stressed in the process that the engine is fully static or the engine produces incentives, therefore the effects of reducing vibration transfer paths and eliminating over-constraints are achieved, and better NVH (Noise, Vibration and Harshness) performances can be realized.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a front suspension assembly for a power assembly. Background technique [0002] The powertrain suspension structure is an indispensable part of the car. It is installed between the powertrain and the subframe. It mainly performs the following functions: supporting the weight of the powertrain and determining the position of the powertrain; isolating the transmission of the engine to the body vibration; withstand the torque and dynamic load output by the powertrain; act as a shock absorber to attenuate the vibration caused by uneven road surfaces. A good suspension structure design is conducive to improving the idling vibration and acceleration noise of the vehicle, thereby improving the comfort of the vehicle. [0003] NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance is an important performance index in the new car development process, and has become the focu...

AI Technical Summary

Problems solved by technology

It is impossible for the front suspension assembly of this structure to be completely free of force. When the engine is working, even if the component is not under static force, the suspension will still function when the engine vibrates. To constrain the vibration of the powertrain and transmit the excitation, thus affecting the vibration isolation performance of the system
