Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings.

[0027] see Figure 2 to Figure 6 A mounting seat for the rear coil spring shown in the figure includes a rubber body 1 and a metal ring frame 2) disposed therein. A rear coil spring contact part 14 is arranged under the rubber body; the metal ring frame 2 has a ring thickness 22 and a ring width 23; the metal ring frame 2 and the rubber body 1 are integrated into a whole by vulcanization, and the metal ring frame 2 The distance from the bottom of the rubber body 1 is 2 / 3 of the thickness 12 of the body. When the whole vehicle is subjected to a small shock, the mounting seat on the rear coil spring can be compressed and deformed and absorb energy to meet the requirements of vibration reduction and noise reduction; when the whole vehicle is subjected to a large shock, the rear coil spring has enough force in the process of transmitting force. Stiffness guarantees durab...

Abstract

The invention relates to an upper mounting seat of a rear spiral spring. The upper mounting seat comprises a rubber body and a metal ring framework arranged in the rubber body, and is characterized in that the rubber body is ring-shaped and has body thickness and body width, and a rear spiral spring contact part is arranged below the rubber body; the metal circular ring framework has a circular ring thickness and a circular ring width; and the metal circular ring framework and the rubber body are integrated through vulcanization, and the distance between the metal circular ring framework and the lower portion of the rubber body is 2 / 3 of the thickness of the rubber body. The requirement for vibration and noise reduction of the whole vehicle can be met, and the requirement for durability and disengagement avoidance of upper mounting seat of the rear spiral spring can also be met.

Description

technical field [0001] The invention relates to an automobile chassis suspension system, in particular to a rear coil spring upper mounting seat. Background technique [0002] The multi-link independent suspension spring behind the existing vehicle chassis and the rear shock absorber are separated, and the rear coil spring is connected with the vehicle body after being assembled with the rubber upper seat and the metal bracket. The main purpose of the rubber upper seat is to reduce vibration and noise, transmit spring force, and not conduct force. Therefore, the rubber upper seat is generally a pure rubber structure with only one piece. With the increase in design size and load of automobiles, the dynamic mechanics of the rubber upper seat of pure rubber structure can neither meet the requirements of vibration and noise reduction of automobiles under small impact conditions, nor can it meet the requirements of maintaining durability and avoiding breakout under large impact c...
