Description

An automobile transmission suspension mechanism

technical field

The utility model relates to an automobile component, in particular to an automobile transmission suspension mechanism for supporting a transmission, belonging to the technical field of automobiles.

Background technique

The main function of the automotive powertrain mount is to support and connect the powertrain, withstand dynamic and static loads under various working conditions, and control the displacement of the powertrain in any direction, so that it is compatible with other parts in the cabin and the body. No interference occurs; in addition, vibration absorption, vibration isolation, and noise reduction must be achieved to meet the requirements of vehicle noise, vibration, and comfort. As the main part of the powertrain, the transmission mostly adopts rubber suspension for its existing suspension mechanism. It consists of two parts, namely sheet metal parts and rubber parts. as a shock absorber. Rubber parts are elastic materials with space spring characteristics, can withstand loads in multiple directions, and can better absorb vibration and impact energy. However, due to the space spring characteristics of the rubber parts, the powertrain will have a large positional deformation under extreme conditions such as braking and rapid acceleration, which will cause interference between the transmission and accessory systems and the body and other accessories, affecting the quality of the vehicle and component life.

Utility model content

The utility model is used to solve the defects of the above-mentioned prior art and provide a suspension mechanism of an automobile transmission that can limit the deformation of the suspension mechanism.

The said problem of the utility model is solved by the following technical solutions:

A suspension mechanism for an automobile transmission, consisting of an upper bracket, a lower bracket and a rubber pad, the rubber pad is located between the upper bracket and the lower bracket and is fixed with the two, and its special feature is: the lower part of the upper bracket There is a limit rod extending downward, and the mechanism is also provided with a base, which is located at the lower part of the lower bracket and fixedly connected with the lower bracket. The base is provided with a limit groove corresponding to the position of the limit rod. The lower end of the position rod is located in the limit groove.

In the suspension mechanism of the above-mentioned automobile transmission, the lower end of the limit rod is a rubber limit head, and the distance between the rubber limit head and the limit groove is 10-15 mm.

The utility model improves the problem of large position deformation of the existing automobile transmission suspension mechanism under extreme working conditions such as braking and rapid acceleration, and adds a limit rod and a limit groove that are mutually adapted, and the limit rod One end is located in the limiting groove. When the car is running normally, the limit rod and the limit groove will not affect the buffering and shock absorption function of the transmission suspension mechanism. The rubber used in the rubber will produce a large amount of deformation, so that there will be no interference between the powertrain and accessory systems, the body and other accessories, and the requirement for the powertrain to move less during vehicle operation.
