Description
Technical Field
The utility model relates to a special auto-parts field says in detail a traction damping device of full trailer.
Background
As is known, a full trailer is a trailer with two or more axles, having one axle which can be steered, coupled to a towing vehicle by means of an angularly movable tow bar, which is vertically movable connected to the chassis, the tow bar being free from any vertical forces. The full trailer decelerates and accelerates in the process of advancing, so that the trailer body is greatly impacted, and the trailer body, particularly the traction frame part is damaged.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a traction damping device of a full trailer, which can absorb most kinetic energy and only use few part of the kinetic energy at other parts of the trailer body so as to protect the structure of the trailer body.
The utility model provides a technical scheme that its technical problem adopted is: the traction damping device of the full trailer is provided with a traction ring and is characterized in that the traction ring is fixed at one end of a traction rod, a hydraulic damping mounting seat is fixed at the other end of the traction rod, hydraulic damping is mounted on the hydraulic damping mounting seat, a front limiting plate and a rear limiting plate are sleeved on the traction rod, the front limiting plate is fixed on a shell, the rear limiting plate is fixed with the traction rod, the rear limiting plate can slide in the shell, the front limiting plate is fixed with the shell, a damping spiral spring is sleeved on the traction rod between the front limiting plate and the rear limiting plate, and the damping spiral spring is limited between the rear limiting plate and the front limiting plate.
The utility model has the advantages that the structure is simple, when the tractor decelerates or brakes, the device can absorb kinetic energy, and reduce the impact on the tractor body; the traction damping device has higher protection grade and can be used in severe environments such as low temperature, high humidity and the like; the damping traction device has the advantages of simple structure and process, easy processing, and high safety, reliability and maintainability.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an enlarged view of a portion a of fig. 1.
In the drawing, 1, a traction ring, 2, hydraulic damping, 3, a front limiting plate, 4, a rear limiting plate, 5, a damping spiral spring, 6, a hydraulic damping mounting seat, 7, a shell and 8, a traction rod are arranged.
Detailed Description
In the figure, the utility model discloses be equipped with traction ring 1, traction ring 1 fixes the one end at traction lever 8, traction lever 8 other end is fixed with hydraulic damping mount pad 6, install hydraulic damping 2 on the hydraulic damping mount pad 6, spacing board 3 and back spacing board 4 before the cover is equipped with on traction lever 8, preceding spacing board 3 is fixed on casing 7, back spacing board 4 is together fixed with traction lever 8, back spacing board 4 can slide in casing 7, preceding spacing board 3 is together fixed with casing 7, the cover is equipped with damping coil spring 5 on traction lever 8 between preceding spacing board 3 and the back spacing board 4, damping coil spring 5 is spacing between back spacing board 4 and preceding spacing board 3.
The utility model discloses traction ring 1 is connected with hydraulic damping 2 through hydraulic damping mount pad 6, and damping helical spring 5 is located between limiting plate 3 and the back limiting plate 4 before, and traction lever 8 penetrates damping helical spring 5. When the full trailer decelerates or brakes, the hydraulic damping damper 2 and the damping spiral spring 5 are compressed, and the kinetic energy is converted into heat to be dissipated into the atmosphere, so that the purposes of absorbing the kinetic energy and reducing the impact on other parts of the trailer body are achieved. After the deceleration or braking is finished, the hydraulic damping damper 2 and the damping spiral spring 5 are reset.
Claims (1)
