Description

Automobile thrust rod assembly

Technical Field

The utility model relates to an automobile distance rod assembly belongs to auto-parts technical field.

Background

The automobile thrust rod is mainly applied to a single-axle or double-rear-axle heavy automobile of a non-independent suspension of a truck or a passenger car, a frame and an axle are connected, the purpose of the automobile thrust rod is mainly to overcome the defect that a steel plate spring can only transmit vertical force and lateral force faces and can not transmit traction force, braking force and corresponding reaction moment, the existing thrust rod generally comprises a rod body, two ends of the rod body are provided with ball head shells, mandrels are arranged in the ball head shells, elastic bodies are arranged between the mandrels and the inner walls of the ball head shells, the existing mandrels and the ball head shells are difficult to assemble, the sealing performance of two end parts of the ball head shells is poor after the assembly, silt easily enters the ball head shells, internal abrasion is accelerated, the performance of the whole assembly is reduced, and the.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that a car distance rod assembly is provided, make things convenient for the installation of dabber and assembly back bulb shell both ends have good sealing performance, can solve the not enough of prior art.

The technical scheme of the utility model is that: the utility model provides an automobile distance rod assembly, includes the body of rod, and body of rod both ends have the bulb shell, and the appearance intracavity of bulb shell is equipped with the dabber, is equipped with the elastomer between dabber and the bulb shell inner wall, the opening that holds chamber one end is the shoulder hole, and the opening part of the other end is provided with the draw-in groove, be provided with the jump ring in the draw-in groove, spacing first bearing seal between elastomer and the shoulder hole, spacing second bearing seal that has between elastomer and the jump ring, first bearing seal all includes skeleton and the rubber body of cladding on the skeleton with the second bearing seal, the rubber body extends the lip mouth that forms and dabber contact to the skeleton inboard. During assembly, the first shaft seal is firstly packaged into the containing cavity, the core shaft and the elastomer are packaged into the containing cavity, the second shaft seal is finally packaged and is limited and fixed by the clamp spring, the lip of the first shaft seal and the lip of the second shaft seal are in contact with the core shaft, the sealing performance of two ends of an opening of the containing cavity is improved, silt cannot easily enter the ball head shell, internal abrasion is reduced, and the service life is prolonged.

The number of the lips is two, the two lips are arranged up and down, and a buffer groove is formed between the two lips. Set up two lips and increase sealed effect, the dashpot provides the space that a deformation takes place for lip deformation simultaneously, strengthens its and the follow-up nature of dabber, avoids causing wearing and tearing with the rigid contact of dabber.

Furthermore, lubricating oil is filled in the buffer groove. Reduce wearing and tearing, reinforcing dabber rotation flexibility.

And a wear-resistant layer is arranged at the contact position of the inner side of the lip opening and the mandrel. Further reducing abrasion and prolonging service life.

To sum up, the utility model provides a make things convenient for the installation of dabber and assembly back bulb shell both ends have good sealing performance's car distance rod assembly.

Shown in the figure: a rod body 1; a ball head housing 2; a mandrel 3; an elastic body 4; a stepped hole 5; a first shaft seal 6; a second shaft seal 7; a clamp spring 8; a skeleton 9; an upper lip 10; a lower lip 11; a buffer tank 12; and a wear resistant layer 13.

Detailed Description

The embodiment of the utility model provides a: the utility model provides an automobile distance rod assembly, including the body of

rod

1, 1 both ends of the body of rod have bulb shell 2, bulb shell 2 hold intracavity and be equipped with dabber 3, be equipped with elastomer 4 between dabber 3 and the 2 inner walls of bulb shell, the opening that holds chamber one end is shoulder hole 5, the opening part of the other end is provided with the draw-in groove, be provided with jump ring 8 in the draw-in groove, it has first bearing seal 6 to be spacing between elastomer 4 and the shoulder hole 5, it has second bearing seal 7 to be spacing between elastomer 4 and the jump ring 8, first bearing seal 6 all includes skeleton 9 and the cladding rubber body on skeleton 9 with second bearing seal 7, skeleton 9 is the metal component, the rubber body is to the inboard lip that extends formation and dabber 3 contacts. During assembly, the first shaft seal 6 is firstly arranged in the containing cavity, the core shaft 3 and the elastomer 4 are arranged in the containing cavity, the second shaft seal 7 is arranged at last and matched with the clamping groove through the clamping spring 8 for limiting and fixing, the lip openings of the first shaft seal 6 and the second shaft seal 7 are in contact with the core shaft 3, the sealing performance of two ends of an opening of the containing cavity is improved, silt cannot easily enter the ball head shell 2, internal abrasion is reduced, and the service life is prolonged.
