Description

Technical Field

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

[0002] The suspension system is the general term for all force-transmitting connection devices between the frame and axles or wheels of a car. Its function is to transmit the forces and torques acting between the wheels and the frame, to cushion the impact forces transmitted to the frame or body by uneven roads, and to attenuate the vibrations caused thereby, to ensure that the car can run smoothly.

[0003] For example, Chinese patent literature discloses an automobile cantilever assembly [application number: 201320227672.7; authorization announcement number: CN203211034U], which includes a main body bracket, a bushing and a ball pin assembly, the main body bracket is provided with a ball head hole and a bushing hole; the ball pin assembly includes a ball pin, a ball pin seat and a ball pin dust cover, the ball pin includes a ball head and a rod, the ball head is arranged in the ball pin seat, the ball pin seat is provided with a blind hole for accommodating the ball head, and the bottom end surface of the blind hole is hemispherical; a card slot is provided on the side wall of the blind hole, an elastic cover plate is provided on the upper end of the card slot, the elastic cover plate is provided with a through hole for the ball head to pass through, and the elastic cover plate is carded in the card slot.

[0004] The above-mentioned automobile suspension arm assembly is relatively convenient to assemble, but its dustproof effect is poor, the dust cover is easy to loosen after long-term use, and its two ends are easy to separate from the rod and the ball pin seat, causing dust and rainwater to enter the ball pin seat and the ball head, affecting the service life of the suspension arm, and it is impossible to add lubricant between the ball pin seat and the ball head that have been used for a long time, resulting in incomplete lubrication between the ball pin seat and the ball head, and the basic conditions for normal use of the ball head cannot be guaranteed. Summary of the invention

[0005] The utility model aims to solve the above problems existing in the prior art and provides an automobile cantilever assembly with good dustproof effect, lubrication and long service life.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an automobile cantilever assembly, including a main body bracket, a bushing is rotatably embedded and connected to the left side of the front side of the main body bracket through a bearing, a ball pin seat is fixedly embedded and connected through the right side of the surface of the main body bracket, a ball head is rotatably connected to the inner wall of the ball pin seat, a rod is welded to the top of the ball head, a dustproof mechanism is installed between the ball pin seat and the rod, and a lubrication mechanism is installed at the bottom of the ball pin seat.

[0007] The automobile cantilever assembly is equipped with a dustproof mechanism and a lubricating mechanism on the traditional automobile cantilever assembly. The dustproof mechanism prevents the dustproof rubber sleeve from being easily loosened after long-term use, and the two ends thereof are not easily separated from the rod and the ball pin seat, so that dust and rainwater will not enter the ball pin seat and the ball head, thereby improving the service life of the suspension arm. The lubricating mechanism can add lubricant between the ball pin seat and the ball head that have been used for a long time, so that the ball pin seat and the ball head are fully lubricated, thereby effectively ensuring the basic conditions for the normal use of the ball head.

When the connecting rope is in use, the dustproof rubber sleeve is first sleeved on the surface of the rod and the ball pin seat, and the connecting rope is pulled to move. Under the action of the short block limit, one end of the connecting rope moves in the short block. After it cannot move, the fixing bolt is rotated to make one end of the connecting rope closely contact with the surface of the connecting rope, thereby firmly fixing the connecting rope and the dustproof rubber sleeve on the surface of the rod and the ball pin seat.

[0009] In the above-mentioned automobile cantilever assembly, springs are fixedly connected to the inside of both ends of the dustproof rubber sleeve, and the number of the springs is several. In actual use, under the action of the spring elastic force, the protruding parts of the inner walls of the two ends of the dustproof rubber sleeve are stably stuck in the arc grooves on the rod and the ball pin seat to form an effective seal.

[0010] In the above-mentioned automobile cantilever assembly, the lubricating mechanism includes a lubricating oil cylinder, the right side of the lubricating oil cylinder is connected with a bend pipe, the end of the bend pipe away from the lubricating oil cylinder is connected with the bottom of the ball pin seat, the left side of the lubricating oil cylinder is fixedly connected with an electric telescopic rod, the output end of the electric telescopic rod passes through the lubricating oil cylinder and is fixedly connected with a piston, and the surface of the bend pipe close to one end of the lubricating oil cylinder is installed with an electric control valve. When the lubricating oil cylinder is actually used, it controls the extension of the electric telescopic rod and the opening of the electric control valve. The extension of the electric telescopic rod pushes the piston to move, so that the lubricating oil in the lubricating oil cylinder is transported to the ball pin seat through the bend pipe, lubricating the ball pin seat and the ball head, and reducing friction loss.

[0011] In the above-mentioned automobile cantilever assembly, a connecting rod is provided through the bottom of the right side of the lubricating oil cylinder, one end of the connecting rod is fixedly connected to the right side of the piston, the other end of the connecting rod is fixedly connected to a feedback block, a fixed block is provided on the surface of the connecting rod, the top of the fixed block is fixedly connected to the right side of the bottom of the lubricating oil cylinder, and a distance sensor is embedded and fixedly connected to the left side of the fixed block. In actual use, the movement of the piston drives the movement of the connecting rod and the feedback block, and the distance sensor monitors the distance between it and the feedback block, effectively feeding back the amount of lubricating oil in the lubricating oil cylinder and controlling the amount of lubricating oil added each time.

[0012] In the above-mentioned automobile cantilever assembly, the top of the lubricating oil cylinder is fixedly connected to a fixing frame, the top of the fixing frame is fixedly connected to the surface of the main support, and a sealing sleeve is provided between the connecting rod and the lubricating oil cylinder, and the sealing sleeve is sleeved on the surface of the connecting rod. In actual manufacturing, the outer surface of the sealing sleeve is fixedly connected to the surface of the lubricating oil cylinder, and the connecting rod and the lubricating oil cylinder are sealed to effectively prevent leakage of lubricating oil.

[0013] In the above-mentioned automobile cantilever assembly, the surfaces of the rod and the ball pin seat are both provided with arc grooves, and the arc grooves are adapted to the inner walls of the two ends of the dustproof rubber sleeve. In actual use, the protruding parts of the inner walls of the two ends of the dustproof rubber sleeve are stably stuck in the arc grooves on the rod and the ball pin seat, forming an effective seal.

[0014] Compared with the prior art, the advantages of the automobile suspension arm assembly are as follows: the dustproof rubber sleeve is not easy to loosen after long-term use, and its two ends are not easy to separate from the rod and the ball pin seat, so that dust and rainwater will not enter the ball pin seat and the ball head, thereby improving the service life of the suspension arm, and lubricant can be added between the ball pin seat and the ball head that have been used for a long time, so that the ball pin seat and the ball head are fully lubricated, effectively ensuring the basic conditions for the normal use of the ball head and prolonging the service life.
