Abstract
Description
Technical Field
[0001] This utility model relates to the field of engine suspension bushing technology, specifically to an engine suspension damping bushing with good cushioning effect. Background Technology
[0002] The suspension is located between the car frame and the axle. Its function is to transmit the forces and torques acting between the wheels and the frame, and to buffer the impact forces transmitted from uneven road surfaces to the frame or body, and reduce the resulting vibrations to ensure that the car can drive smoothly. Among them, the bushings play an extremely important role in buffering and damping.
[0003] In the prior art, the authorized patent with publication number CN213711712U discloses a suspension bushing for automobiles, including an outer cylinder, an inner cylinder, and a buffer portion filled between the outer and inner cylinders; the buffer portion has a buffer cavity, and a buffer reinforcement block is embedded in the buffer portion, with the buffer cavity and buffer reinforcement blocks arranged alternately. The two ends of the buffer reinforcement block abut against the outer and inner cylinders respectively. A first locking block is fixedly disposed on the outer cylinder, and a second locking block is fixedly disposed on the inner cylinder. The two ends of the buffer reinforcement block have a first locking groove and a second locking groove respectively, with the first locking block engaging in the first locking groove and the second locking block engaging in the second locking groove. This application has the effect of improving the overall buffering performance.
[0004] However, the above technical solution still has the following shortcomings in use: the device only uses a rubber buffer for cushioning, which has a very limited cushioning effect. Especially when encountering a large impact, the rubber buffer is easily deformed and damaged, losing its cushioning capacity. To address this, we propose an engine suspension damping bushing with better cushioning performance to solve the aforementioned problems. Utility Model Content
