A kind of cargo vehicle door-hinge device
Technical field
The present invention relates to door hinge device, particularly a kind of cargo vehicle door-hinge device.
Background technology
Automotive door hinge is an important device of arrangements for automotive doors, and whether its structure is reasonable, not only has influence on the appearance and modeling of automobile, but also has influence on the performance and the application life of arrangements for automotive doors.At present the used hinge of cargo vehicle car door mainly contains two types: 1, adopt external, though simple in structure and low in cost, the hinge that exposes has influenced the appearance and modeling of automobile; Though 2 adopt built-inly, can not influence the appearance and modeling of automobile, complex structure, cost is higher.
Summary of the invention
The present invention proposes a kind of cargo vehicle body hinge, and it can overcome the problems referred to above.
This cargo vehicle door-hinge device provided by the invention, it is characterized in that mainly forming by hinge fixed bearing, hinge through bearing, door pillar cover of upholstery, pivot and axle sleeve, the hinge fixed bearing is installed on the car door column, the pre-buried nut that is welded with on the car door column, the hinge fixed bearing firmly is connected with the car door column by bolt and spring washer; The hinge through bearing is installed on the door frame, the pre-buried nut that is welded with on door frame, and the hinge through bearing firmly is connected with door frame by bolt and spring washer.
Described hinge fixed bearing forms with the cast steel manufacturing, the hinge through bearing also forms with the cast steel manufacturing, hinge fixed bearing shaft hole two ends are separately installed with axle sleeve, pivot is hinged by axle sleeve with hinge fixed bearing and hinge through bearing, with the axle sleeve of copper alloy manufacturing with have higher wear resistance after the pivot of steel cooperates.
Each two hinge means of car door use and car door column are hinged, place within car door pillar trim cover and the car door door face board, can not influence the appearance and modeling of automobile.
This cargo vehicle door-hinge device provided by the invention, itself has position limiting structure door hinge device, can guarantee when door opening degree is 72 ° spacingly, and the opening angle of car door is bigger, and the turnover car door is comparatively convenient.The hinge fixed bearing can firmly be connected with the car door column with bolt and spring washer easily, and the hinge through bearing can firmly be connected with door frame with bolt and spring washer easily.Each two hinge means of car door use and car door column are hinged, and whole apparatus structure is simple, easy accessibility, critical piece forms with the cast steel manufacturing, has higher intensity, and not only cost of production is low, and have long application life, can be widely used in cargo vehicle.

Fig. 1 is a general structure front view of the present invention.
Fig. 2 is a general structure vertical view of the present invention.
Fig. 3 is that the A-A sectional view among Fig. 2 is hinge fixed bearing and hinge through bearing syndeton schematic diagram.
Each label is in Fig. 1~3: 1-car door column, 2-bolt, 3-spring washer, 4-hinge fixed bearing, 5-hinge through bearing, 6-car door assembly, 7-car door pillar trim cover, 8-pivot, 9-axle sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, the parts relevant with body hinge: car door column 1, car door assembly 6 and the 7 usefulness double dot dash lines of pillar trim cover are represented, do transparence and handle.The hinge fixed bearing 4 of cast steel manufacturing is installed on the car door column 1, and the outside is equipped with pillar trim cover 7, and three bolts 2 of hinge fixed bearing 4 usefulness and spring washer 3 firmly are connected with car door column 1.The hinge through bearing 5 of cast steel manufacturing is installed on car door assembly 6 doorframes, the pre-buried nut that is welded with on car door assembly 6 doorframes, and hinge through bearing 5 can firmly be connected with car door assembly 6 with bolt 2 and spring washer 3 easily.Whole hinge means places within door skin and the pillar trim cover, and the car door crack between a door and its frame less be 6mm, can not influence the automobile appearance moulding.Each two hinge means of car door use and car door column 1 are hinged, and whole apparatus structure is simple, easy accessibility, critical piece forms with the cast steel manufacturing, has higher intensity, and not only cost of production is low, and have long application life, can be widely used in cargo vehicle.
As shown in Figure 2, itself has position limiting structure door-hinge device, when being 72 ° of car door openings in diagram double dot dash line position, when turning to the a1 position, a face of hinge through bearing 5 collides with the b face of hinge fixed bearing 4, thereby the maximum opening angle of restriction car door assembly 6 is 72 °, in the car door opening process, promptly the car door opening angle can not move interference with adjacent component less than each parts of each position car door assembly 6 of 72 °.In a word, the opening angle of car door is bigger, and the turnover car door is comparatively convenient.
As shown in Figure 3, the parts car door assembly 6 usefulness double dot dash lines relevant with body hinge are represented, do transparence and handle.It is hinged by axle sleeve 9 with hinge fixed bearing 4 and hinge through bearing 5 that 9, one pivots 8 of two axle sleeves have been installed at hinge fixed bearing 4 shaft hole two ends, and axle sleeve 9 copper alloy manufacturing and has higher wear resistance after the pivot 8 of steel cooperates.The pre-buried nut that is welded with on car door assembly 6 doorframes, hinge through bearing 5 can firmly be connected with car door assembly 6 with bolt 2 and spring washer 3 easily.
