Description
Technical Field
The utility model belongs to the technical field of new energy automobile, especially, relate to a new energy automobile braking electron vacuum pump vibration isolation device.
Background
In recent years, with the development and popularization of new energy automobiles, an Electronic Vacuum Pump (EVP) has become a main vacuum source of an automobile vacuum power-assisted brake system. Noise generated when a hybrid electric vehicle and a pure electric vehicle work in an EVP mode under the working condition that a brake pedal is stepped on in an idling mode is paid more and more attention by customers, the noise is mainly transmitted into the vehicle through a vehicle body structure, and the position arrangement and the shock insulation structure form of the hybrid electric vehicle are the most main factors influencing the noise in the vehicle.
In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems: the EVP is arranged on the power assembly, and good vibration and noise reduction effects can be realized through the suspension of the power assembly. The EVP shock insulation design is particularly important when the power assembly cannot be fixed on a vehicle body longitudinal beam due to the limitation of the total arrangement space. The existing new energy vehicle EVP basically adopts a primary shock insulation structure, but 1-order and harmonic-order noises of EVPs of different types and brands have obvious difference, so that even if the noise response size in the vehicle in the same shock insulation structure is also greatly different, the larger the noise amplitude of the vehicle body is, the larger the noise response in the vehicle is.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an effective noise reduction transmission is provided, the new energy automobile braking electronic vacuum pump vibration isolation device of the big problem partially of EVP noise in the car can be solved.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a new energy automobile braking electronic vacuum pump vibration isolation device comprises:
an electronic vacuum pump;
the electronic vacuum pump is connected with the shock insulation pad connecting support;
the first rubber pad is arranged between the electronic vacuum pump and the connecting part of the shock insulation pad connecting support;
the shock insulation cushion connecting bracket is connected with the vehicle body connecting bracket;
and the second rubber pad is arranged between the connecting part of the vehicle body connecting support and the shock insulation pad connecting support.
And a U-shaped groove is formed in the first rubber pad, and a bolt penetrates through the U-shaped groove to be connected with the electronic vacuum pump and the shock insulation pad connecting support.
The shock insulation cushion connecting support is characterized in that the middle part of the shock insulation cushion connecting support is close to the electronic vacuum pump, and two ends of the shock insulation cushion connecting support are connected with two ends of the vehicle body connecting support.
The end part of the shock insulation cushion connecting support is clamped with the second rubber cushion.
The vehicle body connecting bracket is provided with a projection welding nut matched with the bolt; and the shock insulation connecting bracket is provided with a projection welding nut matched with the bolt.
The hardness of the first rubber pad and the second rubber pad is lower than 50HA, and each rubber pad is provided with a shaft sleeve.
One of the technical scheme has the advantages or beneficial effects that the EVP vibration isolation rate can be increased to more than 30%, noise transmission is effectively reduced, and the problem of large EVP noise in the vehicle can be thoroughly solved.
