Abstract

The invention discloses a heavy truck door hinge which comprises a truck body part and a truck door part. The truck body part and the truck door part are connected through a pin. The truck body part comprises a truck body connecting base; a support is arranged on the truck body connecting base, an arched gear block is arranged at one side of the support, and an S-shaped spring is arranged on the support. The truck door part comprises a door connecting base; a connecting arm is arranged on the door connecting base, and a rotational lug is connected to the other end of the connecting arm, and isconnected with the support through a pin. One end of the S-shaped spring is fixed to the support, and other end of the S-shaped spring is arranged under the pin; a sectorial connecting plate which isin synchronous rotation with the rotational lug is arranged at the outer side of the support at one end of the pin; a plurality of rotating gear shafts are arranged under the sectorial connecting plate in a parallel manner, and are in contact with the S-shaped spring. The heavy truck door hinge has reasonable structure and is firm and durable; with limitation of a gear limit structure and the gear block at the maximum opening position, the heavy truck door can be closed and opened easily and conveniently and is easy to control.

Description

technical field [0001] The invention relates to the technical field of hinge structures, in particular to heavy truck door hinges. Background technique [0002] Because the doors of heavy-duty trucks are heavy, the torsional force of the hinges needs to be relatively large to withstand large torsional forces and open and close the doors smoothly. The hinges of existing heavy-duty trucks have simple structure, insufficient strength, and no gear position limiting structure, etc., which makes it difficult to control the door switch and requires a lot of strength to control. Contents of the invention [0003] The purpose of the present invention is to provide a heavy truck door hinge with a stable and firm structure, which is equipped with a gear limit structure and a gear block limit of the maximum door opening position, so that the door switch is light and easy to control. [0004] In order to achieve the above object, the present invention provides a door hinge for a heavy...
