Problems solved by technology

However, for mass-produced powertrain systems, the rear end of the engine block is often the installation location for starters and other accessories. It is often necessary to make design changes to parts such as oil pans and cylinder blocks, which leads to long transformation periods and high costs

Abstract

An embodiment of the invention provides a support improving power assembly bending and torsional modal. The support is mounted between an engine cylinder block and a gearbox clutch housing. An engineconnecting piece on one end of the support is fixed on the lower part of the engine cylinder block, and a gearbox connecting piece on the other end is fixed on the gearbox clutch housing. Reinforcingribs are arranged between the two connecting pieces, to improve restraint stiffness. The support forms a triangular supporting structure which supports firmly between an engine and a gearbox, and effectively improves restraint stiffness of a connection position of the engine and the gearbox. The support is flexible and convenient in installation, and does not involve changes of original componentsof a power assembly, and reduces transformation difficulty and transformation cost of an existing power assembly. The support is simple in structure, convenient in processing, low in manufacturing cost, and short in manufacturing cycle, and is suitable for engineering application. An embodiment of the invention also provides a vehicle which is installed with the support improving power assembly bending and torsional modal.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a support for lifting the bending and torsion mode of a power assembly. The present invention also provides an automobile with the above bracket. Background technique [0002] With the development of the economy and the improvement of people's living standards, people have higher and higher requirements for vehicles. Customers not only require the vehicle to have good reliability, but also hope that the vehicle's NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance is better, so that the vehicle ride is more comfortable. [0003] The mode is the inherent characteristic of the structural system. Each mode has a specific natural frequency, damping ratio and mode shape. When the excitation frequency is coupled with the natural frequency, the structural system will resonate, that is, vibrate in a small period It can produce a lot of vibration, which can...
