Abstract

An oil bath type air filter bracket, comprising: a connecting bracket and a front bracket and a rear bracket respectively fixed at both ends of the connecting bracket, the connecting bracket is fixed on the vehicle longitudinal beam through several longitudinal beam connecting plates using bolts III and nuts II, The front bracket, rear bracket and connecting bracket form a U-shaped structure. The distance between the front bracket and the rear bracket matches the width of the air filter. The air filter is inserted between the front bracket and the rear bracket. It is fixed on the front bracket and the rear bracket by bolt II and nut I. By fixing the air filter between the U-shaped structure formed by the front bracket, the rear bracket and the connecting bracket, a cantilever connection and fixing structure is formed, the air filter is not easy to vibrate and deform, and its service life is improved. Without changing the material and meeting the functional requirements, the weight of the bracket itself can be reduced as much as possible.

Description

An oil bath type air filter bracket

technical field

The utility model relates to an oil bath type air filter bracket.

Background technique

Existing automobile oil-bath type air filter (abbreviated as air filter) support consists of a longitudinal beam support, a drawstring, a fixed pin, and a tension pin. Since the material of the air filter housing is PP+GF30%, the housing is easily deformed when tightened. This product is mainly used for dump trucks. When the vehicle is driving on uneven roads, the existing bracket will cause the air filter to vibrate. It is easy to cause cracks on the upper shell of the air filter (connection with the bracket), causing its function to fail.

Contents of the invention

In order to overcome the deficiencies of the above technologies, the utility model provides an oil-bath air filter bracket with compact appearance, small space occupation, low self-weight, good rigidity and strength, and is not easy to deform and vibrate the air filter when fastened.

The technical solution adopted by the utility model to overcome its technical problems is:

An oil bath type air filter bracket, comprising: a connecting bracket and a front bracket and a rear bracket respectively fixed at both ends of the connecting bracket, the connecting bracket is fixed on the vehicle longitudinal beam through several longitudinal beam connecting plates using bolts III and nuts II, The front bracket, the rear bracket and the connecting bracket form a U-shaped structure, the distance between the front bracket and the rear bracket matches the width of the air filter, the air filter is inserted between the front bracket and the rear bracket, and its front and rear sides are respectively It is fixed on the front bracket and the rear bracket by bolt I and by bolt II and nut I.

In order to reduce noise and improve the life of the air filter, a number of rubber pads fixed on the connecting bracket are arranged between the connecting bracket and the air filter.

In order to improve the strength, the connecting bracket is an L-shaped bending structure.

In order to improve the strength, the above-mentioned front bracket and rear bracket are respectively L-shaped bending structures.

The beneficial effect of the utility model is: by fixing the air filter between the U-shaped structure formed by the front bracket, the rear bracket and the connecting bracket, a cantilever connection and fixing structure is formed, the air filter is not easy to vibrate and deform, and its service life is improved. Without changing the material and meeting the functional requirements, the weight of the bracket itself can be reduced as much as possible. Since the connecting bracket is connected to the vehicle longitudinal beam through several longitudinal beam connecting plates, multi-point positioning is adopted, which greatly increases the distance between the bracket and the vehicle. The firm connection of the longitudinal beam further reduces the vibration and noise of the support.

detailed description

Below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 the utility model is described further.

An oil bath type air filter bracket, comprising: a connecting bracket 1 and a front bracket 2 and a rear bracket 3 respectively fixed to both ends of the connecting bracket 1, the connecting bracket 1 is fixed to the automobile through several longitudinal beam connecting plates 5 with bolts III10 and nuts II11 On the longitudinal beam 6, the front bracket 2, the rear bracket 3 and the connecting bracket 1 form a U-shaped structure, the distance between the front bracket 2 and the rear bracket 3 matches the width of the air filter, and the air filter is inserted into the front bracket 2 and the rear bracket 3 Between them, the front and rear sides are respectively fixed on the front bracket 2 and the rear bracket 3 by bolts I7, bolts II8 and nuts I9. By fixing the air filter between the U-shaped structure formed by the front support 2, the rear support 3 and the connecting support 1, a cantilever connection and fixing structure is formed, the air filter is not easy to vibrate and deform, and its service life is improved. Without changing the material and meeting the functional requirements, the weight of the bracket itself can be reduced as much as possible. Since the connecting bracket 1 is connected to the vehicle longitudinal beam 6 through several longitudinal beam connecting plates 5, multi-point positioning is adopted, which greatly increases the weight of the bracket itself. The strong connection between the bracket and the longitudinal beam of the vehicle further reduces the vibration and noise of the bracket.

Several rubber pads 4 fixed on the connecting bracket 1 may be arranged between the connecting bracket 1 and the air filter. The rubber pad 4 can play a role of shock absorption to reduce noise, and can effectively improve the service life of the air filter at the same time.

Further, the connecting bracket 1 is an L-shaped bending structure, and the front bracket 2 and the rear bracket 3 are respectively an L-shaped bending structure. The L-shaped bending structure can not only ensure good strength, but also meet the advantages of light weight, thus further improving the reliability of the use of the oil bath air filter bracket.
