Background technology
The automobile door hinge linkage that the prior art field is commonly used, comprise the carriage A that is installed on the car hold body, be installed in the carriage B on the body and be arranged on carriage A and carriage B between hinge axis, car door is the rotation that certain angle is done in the axle center with the hinge axis.This body hinge structure is widely used in various arrangements for automotive doors and connects.For the car door of extraordinary heavy-duty car, for example panzer, anti-riot car etc., its car door adopts special steel manufacturing, and car door is big and weigh, the body hinge of employing said structure, following bad phenomenon can occur: 1. hinge strength deficiency, door sealing are not tight; 2. adopt common body hinge can cause door to droop.
Summary of the invention
In order to overcome the above-mentioned defective that the prior art field exists, the purpose of this utility model is, a kind of heavy goods vehicles door hinge is provided, and tight and door droops problem because of the not enough door sealing that causes of hinge strength to have solved extraordinary heavy duty vehicle door.
The heavy goods vehicles door hinge that the utility model provides, it comprises hinge arms, roller, elastic positioning machine structure, described elastic positioning machine structure comprises slip yoke, spring, sliding shoe, and described roller is arranged between the slip yoke of hinge arms and elastic mechanism, and spring is arranged between sliding shoe and the slip yoke; Hinge arms one end is arranged on the car door by holder, and the other end is connected with the hinges fixing reservation by hinge axis, and hinge arms can be around hinge axis; Described elastic positioning machine structure is fixedly installed in the hinges fixing reservation, and the hinges fixing reservation is fixedly installed on the body of car cabin.The end face that described hinge arms is connected with roller is provided with several arc grooves.Be provided with axle sleeve between the connecting hole of described hinge axis and hinge arms.It also comprises the adjusting bolt, and this adjusting bolt is arranged on sliding shoe one side of elastic positioning machine structure, regulates bolt and can come adjustment dynamics size by regulating sliding shoe.
When opening car door, the hinge arms of band arc groove promotes roller and moves, and roller drives slip yoke and moves, and makes length of spring compressed, and when the hinge arms of band arc groove turned to certain angle, arc groove and roller matched, and at this moment car door is in an open position.
The heavy goods vehicles door hinge that the utility model provides, its beneficial effect are, this heavy goods vehicles door hinge novel structure, reasonable in design, reliable in structure.Solved rationally and effectively car door in use seal, the door droop tight problem, guarantee cabin body good airproof performance, driver and conductor's personal safety under special circumstances.
