Novel auxiliary frame installing bush

Abstract

The invention discloses a novel auxiliary frame installing bush. The novel auxiliary frame installing bush is simple in structure, low in manufacturing cost and high in practicability, and comprises an inner sleeve, a rubber buffering structure and an outer sleeve, the rubber buffering structure is arranged on the exterior of the inner sleeve, the outer sleeve sleeves the inner sleeve, a top buffering block is arranged on one side of the inner sleeve, a lateral open groove is formed in one side of the top buffering block, a longitudinal open hole is formed in one side of the lateral open groove, and a bottom buffering block is arranged at the bottom of the inner sleeve. Under the synergistic effect of all components of the novel auxiliary frame installing bush, the problem is solved that when a vehicle is driven, longitudinal comfort is poor during longitudinal impact, the roll stiffness of the vehicle is considered, meanwhile, the lateral comfort of the whole vehicle is improved through the designed half-open groove, the practicability of the bush is improved, a lot of costs are saved, and the novel auxiliary frame installing bush is suitable for application and popularization.

Description

technical field [0001] The invention relates to a mounting bush, in particular to a novel auxiliary frame mounting bush, which belongs to the technical field of auto parts application. Background technique [0002] The sub-frame can be regarded as the skeleton of the front and rear axles, which is an integral part of the front and rear axles. The sub-frame is not a complete frame, but a support for the front and rear axles and suspensions, so that the axles and suspensions pass through it and then connect with " The main frame is connected, which is customarily called the "sub-frame". The function of the sub-frame is to block vibration and noise and reduce its direct entry into the compartment, so most of them appear on luxury cars and off-road vehicles, and some cars are also installed on the engine. Sub-frame, the traditional load-bearing body without sub-frame, its suspension is directly connected with the steel plate of the body, so the suspension rocker mechanism of the...

Problems solved by technology

[0002] The sub-frame can be regarded as the skeleton of the front and rear axles, which is an integral part of the front and rear axles. The sub-frame is not a complete frame, but a support for the front and rear axles and suspensions, so that the axles and suspensions pass through it and then connect with " The main frame is connected, which is customarily called the "sub-frame". The function of the sub-frame is to block vibration and noise and reduce its direct entry into the compartment, so most of them appear on luxury cars and off-road vehicles, and some cars are also installed on the engine. Sub-frame, the traditional load-bearing body without sub-frame, its suspension is directly connected with the steel plate of the body, so the suspension rocker mechanism of the front and rear axles are all parts, not an assembly, after the birth of the sub-frame, front and rear The suspension can be assembled on the sub-frame first to form an axle assembly, and then this assembly is installed on the body together. The function of the sub-frame is to block vibration and noise and reduce its direct entry into the compartment, so most of them appear in luxury vehicles. On modern cars and off-road vehicles, some cars are equipped with a sub-frame for the engine. The suspension of the traditional load-bearing body without a sub-frame is directly connected to the steel plate of the body, so the suspension rocker mechanisms of the front and rear axles are scattered. After the birth of the sub-frame, the front and rear suspension can be assembled on the sub-frame to form an axle assembly, and then this assembly is installed on the body together. The current sub-frame installation bushing is Solid rubber, there is no slotted structure, and its structure has the following disadvantages: 1. When the vehicle is impacted in the front and rear directions during driving, because the rubber bushing is a solid all-rubber structure in the front and rear directions, the cushioning effect is poor, which affects the longitudinal comfort of the vehicle , 2. When the vehicle is subjected to lateral impact, because the rubber bushing is an all-rubber structure, the cushioning effect is poor, which affects the lateral comfort of the vehicle. Therefore, a new type of sub-frame mounting bush will surely have a good market prospect
