Problems solved by technology

However, with the continuous improvement of the performance requirements of automobile engines, the existing structure can no longer meet the requirements of vibration and noise indicators.
According to the experimental data, the first-order modal frequency of the current "concave"-shaped connecting plate is relatively low, about 360Hz, and the effect of damping and noise reduction on the engine rear mount itself is not ideal. The current first-order modal frequency requirements of the connecting plate Reach above 450Hz

Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] combine figure 1 , figure 2 The shown shock-absorbing and noise-reducing reinforced engine rear mount is mainly composed of a large bush 1, a small bush 2 and a connecting plate 3. The large bushing 1 is connected with the sub-frame through bolts, the small bushing 2 is connected with the rear suspension bracket through the combination of bolts and nuts, and the rear suspension bracket is connected with the engine again. The large bushing 1 and the small bushing 2 are spaced left and right, and the axes of the two are perpendicular to each other. The connecting plate 3 is arranged between the large bush 1 and the small bush 2, and connects the large bush 1 and the small bush 2 as a whole. The left end of connecting plate 3 is welded with large bushing 1, and the right end of connecting plate 3 is welded with small bushing 2.

[0014] The connecting plate 3 i...

Abstract

The invention discloses a shock-absorbing noise-reducing reinforced engine rear suspension which comprises a large bushing (1), a small bushing (2) and a connecting plate (3). The large bushing (1) and the small bushing (2) are arranged in a left-and-right interval mode, the axis of the large bushing (1) and the axis of the small bushing (2) are perpendicular to each other, and the connecting plate (3) is arranged between the large bushing (1) and the small bushing (2), enables the large bushing (1) and the small bushing (2) to be connected to be a whole and is a punching plate with the concave section. A flat plate (4) is welded to the opening portion of a concave cavity of the connecting plate (3) to seal the open end of the connecting plate (3), the left end of the flat plate (4) is connected with the large bushing (1), and the right end of the flat plate (4) is connected with the small bushing (2). The flat plate is welded to the connecting plate to seal the open end of the connecting plate, on one hand, the integral strength of the rear suspension can be improved, on the other hand, first-order modal frequency of the rear suspension can be improved, and the shock-absorbing noise-reducing effect of the rear suspension is remarkably improved.

Description

technical field [0001] The present invention relates to the automobile power assembly—the parts on the engine, in particular, relates to the structure of the rear suspension of the engine. Background technique [0002] There are usually left mounts, right mounts and rear mounts on the car engine. The engine is connected to the mounts through the mount brackets at the corresponding positions, and the mounts are then connected to the frame, thus forming the left, right and rear mounts of the engine. Mount point. [0003] Usually, the rear suspension of the engine is composed of a large bush, a small bush and a connecting plate. space, and connect the large bush and the small bush as a whole, and the connecting plate is a stamped plate with a "concave" cross-section. [0004] The connecting plate with a "concave" cross-section structure can increase the strength of the connecting plate and improve the effect of shock absorption and noise reduction. However, with the continuo...
