Description
Technical Field
The utility model belongs to the technical field of the automobile shock attenuation technique and specifically relates to a steering wheel syntonizer for optimizing NVH performance is related to.
Background
With the rapid development of the automobile industry, the NVH (vibration, noise, comfort) performance of vehicles is receiving more and more extensive attention. The steering wheel is in direct contact with a driver, and the driver is easily fatigued when the vibration of the steering wheel is too large, so the NVH performance of the steering wheel becomes one of important indexes for evaluating the comfort of a vehicle. Therefore, the NVH performance of the steering wheel is optimized, and the method has important significance for improving the quality of the whole vehicle.
Disclosure of Invention
The utility model provides a steering wheel syntonizer for optimizing NVH performance can take following technical scheme:
a steering wheel syntonizer for optimizing NVH performance, include buffering resonance portion, counter weight portion and the bearing portion that connects gradually through the vulcanization mode.
The buffer resonance part is a rubber block formed by vulcanization injection molding.
The counterweight part is a cast iron block, the upper part of the cast iron block is provided with a mounting groove matched with the rubber block, and two ends of the bottom surface of the mounting groove are provided with accommodating cavities extending downwards.
The bearing part is a metal plate with two ends covered on the containing cavity, a rubber vulcanization injection hole communicated with the containing cavity is formed in the metal plate, two lugs are arranged on the side face of the metal plate, and a mounting hole used for being connected with a steering wheel is formed in each lug.

The utility model provides a steering wheel syntonizer for optimizing NVH performance, simple structure, small in size, easily manufacturing, low cost, simple to operate can show the steering wheel vibration that causes to the automobile body such as reduction engine mounting system, transmission system, exhaust system.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an exploded view of fig. 1.
Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 and 2, the steering wheel resonator for optimizing NVH performance includes a buffering resonance part 1, a counterweight part 2 and a bearing part 3 which are connected in sequence by a vulcanization mode.
Wherein, the buffer resonance part 1 is a rubber block formed by vulcanization injection molding. The counterweight part 2 is a cast iron block, the upper part of the counterweight part is provided with a mounting groove 2.1 matched with the rubber block, and two ends of the bottom surface of the mounting groove 2.1 are provided with accommodating cavities 2.2 extending downwards, so that the counterweight part is easy to manufacture and has lower cost. The damping resonance part 1 can be easily attached above the weight part 2 by means of vulcanization.
The bearing part 3 is a metal plate with two ends covered on the containing cavity 2.2, a rubber vulcanization injection hole 3.2 communicated with the containing cavity 2.2 is arranged on the metal plate 3.1, two lugs 3.3 are arranged on the side surface of the metal plate 3.1, and a mounting hole 3.4 used for connecting a steering wheel is arranged on the lug 3.3. During manufacturing, vulcanized rubber is injected into the accommodating cavity 2.2 through the rubber vulcanization injection hole 3.2, so that the counterweight part 2 and the bearing part 3 can be connected together. In addition, the middle part of the metal plate 3.1 is also provided with a technical lightening hole 3.5. The metal plate 3.1 has high strength and good installation stability.
Will the utility model discloses install the back on the steering wheel, it can fully absorb passes through suspension system, automobile body or frame by the excitation source engine and will vibrate the vibrations that reach the steering wheel to and pass through the vibrations that tire, knuckle, steering linkage etc. will vibrate the vibrations that reach the steering wheel by the excitation source road surface, improve steering wheel NVH performance, improve driver's the comfort level of controlling.
