Abstract
The invention relates to a novel rubber spherical pin for a thrusting rod of a heavy-duty truck, which comprises a pin axle 1, an asbestos gasket 2, an end cover 5, a rubber coating 4, an inner casting 3 and a jam nut 6, which is characterized in that the end cover 5, the rubber coating 4 and the inner casting 3 are vulcanized into an integrated vulcanization composite part, the asbestos gasket 2 and the pin axle 1 are arranged in the inner casting 3, the two ends of the pin axle 1 burkes threads which are arranged on the two ends of the pin axle 1 through the jam nut 6 to prevent the jam nut 6 from falling back, the pin axle 1 is controlled to move in the axial direction, and the pin axle 1 rotates in 360 degrees under a certain twisting moment along the peripheral direction in the vulcanization composite part. The novel rubber spherical pin solves the assembly problem of the thrusting rod, thereby reducing the assembly cost of the thrusting rod. Through improving the structure, the force condition of the rubber spherical pin is improved, and the service life of the thrusting rod is prolonged.
Description
Technical field
The invention belongs to track bar with sphere pin part, particularly a kind of heavy-duty car thrusting rod rubber spherical face pin.
Background technique
Use in the bar sphere pin part in heavy-duty car thrust, rubber sphere pin has obtained using comparatively widely on the heavy-duty car track bar because of characteristics such as its distinctive buffering, damping, weatherability.But the problem that existing rubber sphere pin exists bearing pin along the circumferential direction not rotate freely has brought difficulty for the assembling of track bar, and working life is short, the assembly cost height.
Therefore, domestic each heavy-duty car factory all is being restricted in the use of rubber-like track bar in varying degrees at present, fails to throw on assembly line on a large scale.
Summary of the invention
The new structure that the purpose of this invention is to provide a kind of rubber sphere pin makes the bearing pin of sphere pin become and can along the circumferential direction rotate arbitrarily, with the stress of improvement rubber sphere pin and the assembling condition of distance rod assembly.Thereby improve the working life of track bar, reduce the assembly cost of track bar.
Rubber sphere pin involved in the present invention, form by bearing pin 1, asbestos washer 2, end cap 5, rubber sleeve 4, inner sleeve 3, fastening screw nut 6, end cap 5, rubber sleeve 4, inner sleeve 3 are by being sulfided into as a whole sulfuration component, asbestos washer 2, bearing pin 1 are assemblied in the inner sleeve 3, realizing bearing pin in the circumferencial direction effect of rotation arbitrarily, fastening screw nut 6 with bearing pin 1 and tightly at the two ends of inner sleeve 3 to guarantee that bearing pin 1 can not axial float; Asbestos washer 2 is assemblied in effective seal on fastening screw nut 6 interior edge faces and has lived undesirable substances such as lubricant oil between inner sleeve 3 and the bearing pin 1 and outside dust, silt; With the thread damage at bearing pin 1 two ends, tip upside down on the end face of fastening screw nut, to reach the purpose that fastening screw nut in use can not fall back.
Because end cap 5, rubber sleeve 4, inner sleeve 3 are by the as a whole sulfuration component of sulfuration, bearing pin 1 is assemblied in the hole of inner sleeve 3, when bearing pin 1 is subjected to along the circumferential direction warping force, bearing pin 1 can rotate in inner sleeve 3, has so just alleviated bearing pin 1 360 ° of rotations arbitrarily under certain warping force distance along the circumferential direction in the sulfuration component greatly.
End cap, rubber, inner sleeve are as a whole by sulfuration, and bearing pin is assemblied in the hole of inner sleeve, and when bearing pin was subjected to along the circumferential direction warping force, bearing pin can rotate in inner sleeve, has so just alleviated the suffered shearing force of rubber greatly.And present rubber sphere pin adopts is that end cap, rubber, bearing pin sulfuration is as a whole, and when bearing pin was subjected to along the circumferential direction warping force, bearing pin will direct pull rubber, makes rubber be subjected to very big shearing force, and the damage of rubber will be accelerated.
When the assembling of track bar, must guarantee that the flat side's in bearing pin two ends plane and vehicle frame plane be close to.Rubber sphere pin involved in the present invention since bearing pin along the circumferential direction arbitrarily the rotation, so can easily achieve the above object, and present rubber sphere pin since bearing pin can not along the circumferential direction rotate arbitrarily, so be difficult to satisfy the matching requirements of track bar.
Technique effect of the present invention is: by the improvement of structure, the bearing pin of rubber sphere pin is become and can along the circumferential direction rotate arbitrarily, thoroughly solved the assembly problem of track bar, reduced the assembly cost of track bar; By improving of structure the force-bearing situation of rubber sphere pin, prolonged working life of track bar.
