Problems solved by technology

[0004] However, the traditional rubber suspension cushion also has several disadvantages: first, because the dynamic and static stiffnesses of the three surfaces of the rubber suspension are inconsistent, when the rubber is subjected to shear force or twisting force, it is easy to cause the suspension cushion to collapse. The vibration isolation rate is reduced, and it is easy to damage the internal molecular structure of the suspension cushion, reducing the service life of the suspension cushion; secondly, when the powertrain is in some special working conditions, the rubber material is prone to large position deformation, resulting in Interference between powertrain and accessory system, body and other accessories affects the ride comfort of the whole vehicle and the service life of parts

Embodiment 1

[0017] The plate body of the upper splint 10 located in the body bracket 50 and the members of the body bracket 50 are in a state of avoiding each other. The upper splint 10 is provided with a bracket 40 upwards. The upper end surface of the bracket 40 coincides with the installation surface of the gearbox. The lower splint 20 It fits with the lower bottom plate 52 of the vehicle body bracket 50, and the plate surface of the lower bottom plate 52 coincides with the mounting surface of the vehicle body, such as Image 6 shown.

[0018] combine figure 2 , 3 , 4, 5, 6, the plate body of the upper splint 10 in the body frame 50 is bent toward the side where the lower splint 20 is located, and is located in the space between the upper baffle plate 51 and the lower floor 52 of the body frame 50 Inside, the bent portion is in a Z shape, and the plate surface after bending is parallel to the plate surface of the lower splint 20 . The width of the upper splint 10 is approximately e...

Embodiment 2

[0021] The difference between the second embodiment and the first embodiment is that the plate body of the upper splint 10 in the body bracket 50 is bent toward the side where the lower splint 20 is located, and is in a mutual avoidance state with the body bracket 50, that is, it is in the body bracket In the space between the upper baffle plate 51 and the lower bottom plate 52 of the 50, the bent portion is L-shaped, and the plate surface after bending is perpendicular to the plate surface of the lower splint 20 . like Figure 7 , 8 shown. For the rest of the second embodiment, refer to the first embodiment.

[0022] In summary, the core of the present invention is to fasten and connect the powertrain and the suspension cushion through the bracket 40, and after the powertrain is double damped by the bracket 40 and the rubber body 30, the deformation of the suspension cushion can be effectively limited. At the same time, the plate body of the upper splint 10 located in the ...

Abstract

The invention relates to a suspension cushion of a gearbox. The suspension cushion comprises an upper plywood, a lower plywood and a rubber body clamped between the upper plywood and the lower plywood, wherein, the upper plywood is positioned in a plate body in a bracket of a vehicle body and is in an avoidance state with the components of the bracket of the vehicle body; the bracket is arranged over the upper plywood; the upper end face of the bracket is matched with a mounting surface of the gearbox while the lower plywood is abutted on a lower bottom plate of the bracket of the vehicle body, and the face of the lower bottom plate is matched with the mounting surface of the vehicle body. The arrangement of the bracket on the upper plywood can ensure buffering and vibration damping to a great extent and reduce the deflection of the suspension cushion; meanwhile, the avoidance of the upper plywood positioned in the plate body in the bracket of the vehicle body with the components of the bracket can prevent the upper plywood from clashing with the bracket of the vehicle body, thus ensuring the good effect of limiting.

Description

technical field [0001] The invention relates to an automobile power assembly suspension system, in particular to a gearbox suspension cushion. Background technique [0002] The main function of the automotive powertrain suspension system is to support the engine powertrain, bear the dynamic and static loads under various working conditions, and keep the displacement of the engine powertrain in all directions within an acceptable range. It does not interfere with other components in the front cabin and the body; secondly, it is required to achieve vibration absorption, vibration reduction and vibration isolation, and reduce noise to meet the NVH performance requirements of the vehicle. [0003] Traditional rubber suspension pads generally consist of two parts, such as the figure 1 Shown: that is, the upper supporting frame 1, the lower mounting frame 3 (mainly stamped parts of sheet metal), the mounting nut 4, and the rubber body 2, which are vulcanized and formed. Rubber i...
