Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and particularly relates to an adjustment arm cover plate assembly. Background Art

[0002] Commercial vehicles face complex road conditions, with many muddy, sandy, dusty, long slopes, bends, wading, and high-amplitude sections, which place stringent requirements on the sealing performance of the adjusting arm. The cover assembly is the key seal of the adjusting arm, and its sealing requirements are particularly critical.

[0003] The current adjustment arm cover plate usually adopts a single-layer sealing component, which has a general sealing effect and cannot meet customers' increasingly higher sealing performance requirements. In addition, during long-term use, the sealing component needs to be replaced frequently, the operation process is relatively complicated, and unnecessary manpower is wasted. Summary of the invention

[0004] The utility model aims to provide an adjustment arm cover plate assembly with good sealing performance in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an adjustment arm cover plate assembly, including an arm body, an outer ring at the top of the arm body is penetrated by a mounting hole, a gear ring is installed at the bottom of the arm body, an O-ring is filled between the top of the gear ring and the bottom of the arm body, a cover plate is installed at the top of the arm body, a sealing ring is fixedly installed on the inner ring of the cover plate, and a sealing gasket is filled between the cover plate and the top of the arm body.

[0006] In actual application, the gear ring and the sealing ring are fitted and sealed to meet the locking torque requirements, improve the installation stability of the cover assembly, and further enhance the sealing effect. Through the use of sealing gaskets, the cover installation point can be effectively sealed to improve the sealing effect.

[0007] In the above-mentioned adjustment arm cover plate assembly, the number of the mounting holes is seven, and the shape of the mounting holes is hexagonal, and a positioning hole is opened at the center of the top of the cover plate.

[0008] In the above-mentioned adjustment arm cover plate assembly, the bottom of the sealing ring is in contact with the bottom of the gear ring, and the outer ring of the sealing ring is in contact with the inner ring of the arm body.

[0009] In the above-mentioned adjustment arm cover plate assembly, the gear ring and the cover plate are in a covering state, and the bottom of the cover plate is tightly fitted with the top of the arm body. In practical application, the use of the cover plate can effectively seal the connection between the arm body and the accessories, and the installation is stable and easy to assemble.

[0010] In the above-mentioned adjusting arm cover assembly, an oil storage cylinder is installed through the front side of the top of the arm body, a sealing cover is provided on the top threaded sleeve of the surface of the oil storage cylinder, and the bottom of the oil storage cylinder passes through the arm body and is connected to an oil pipeline.

[0011] In the above-mentioned adjustment arm cover assembly, the oil delivery pipe is in an inclined state, and the oil outlet end of the oil delivery pipe faces the outer ring of the gear ring. In practical applications, the oil delivery pipe can be sealed by using a sealing cover to prevent dust from entering, and the lubricating oil can be transported by using the oil delivery pipe and the oil storage cylinder, so that the staff can easily apply the lubricating oil.

[0012] Compared with the prior art, the advantages of the present adjusting arm cover assembly are: the gear ring and the sealing ring are fitted together to meet the conventional locking torque requirements, the installation stability of the cover assembly is improved, the sealing effect is further enhanced, and the cover is doubly sealed by the sealing ring and the O-ring, so there is no need to frequently replace the sealing assembly, and the sealing requirements can be met.
