Abstract
The utility model discloses a car part, and in particular discloses a hinge assembly for a sliding door. The hinge assembly comprises a middle hinge seat, a roller support, a bearing roller, and a guiding roller, wherein the bearing roller and the guiding roller are mounted on the roller support, the roller support and the middle hinge seat are hinged with each other through a hinge shaft, a noise reduction shaft sleeve is sleeved outside the hinge shaft, a torsional spring is sleeved outside the noise reduction shaft sleeve, one end of the torsional spring is fixed on the middle hinge seat, and the other end of the torsional spring is fixed on the roller support. As the torsional spring of the hinge assembly structure for the sliding door in the prior art is directly wound on the hinge shaft, friction is easily generated between the torsional spring and the hinge shaft when the torsional spring and the hinge shaft relatively rotate, cacophony is generated in the process, and the above technical shortcomings are solved by adopting the hinge assembly disclosed by the utility model. When the angle between the middle hinge seat and the roller support of the hinge assembly disclosed by the utility model is changed for relative rotation movement, the friction is not directly generated between the torsional spring and the hinge shaft, so that the generation of cacophony can be effectively prevented, and the application performance of the hinge assembly can be effectively improved.
Description
Technical field
The utility model relates to hinge assembly in a kind of auto parts machinery, particularly sliding door.
Background technology
Body hinge is the parts that car door is connected with car body, the weight of body hinge carrying car door on the one hand, and body hinge is as car door opening or the hinge of closing on the other hand.Because sliding door can reduce the space of vehicle-body width direction when opening, thereby be widely used in the vehicles such as station wagon, minicar, between car door and car body, general three of the upper, middle and lower hinge that adopts is connected, and in sliding door wherein, hinge mainly plays load-bearing and guiding.
In existing sliding door hinge mainly by hinge seat, rolling wheel support, load-bearing roller and guide roller form, load-bearing roller and guide roller are arranged on rolling wheel support, between rolling wheel support and middle hinge seat, by hinge axis, be hinged, be wound with torsion spring on hinge axis, middle hinge seat is connected with car door, car body is provided with guide rail, load-bearing roller and guide roller are stuck in guide rail and can roll along it, openly in Chinese patent literature, provide hinge in a kind of sliding door of automobile as what the patent No. was 201220405501.4, comprise middle hinge seat, rolling wheel support, load-bearing roller and guide roller, load-bearing roller and guide roller are arranged on rolling wheel support, between rolling wheel support and middle hinge seat, by hinge axis, be hinged, be wound with torsion spring on hinge axis, middle hinge seat is the integral type structure, middle hinge seat is provided with " U type " lug protruded to a side, lug is provided with the through hole of two correspondences, lug is positioned at hinged seat on rolling wheel support suitable with it, hinge axis is through the through hole on hinged seat and lug, it is little that it has a volume, be convenient to install and the low characteristics of cost.But in said structure, torsion spring directly is wound on hinge axis, torsion spring and hinge axis all adopt metal material usually simultaneously, therefore angle occurs between the two changes, during operation for the relative rotation, easily produce friction between torsion spring and hinge axis, and send ear-piercing noise, have a strong impact on its functional performance.
The utility model content
The purpose of this utility model is that hinge assembly in a kind of sliding door of high functional performance is provided in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, hinge assembly in the designed sliding door of the utility model, comprise middle hinge seat, rolling wheel support, load-bearing roller and guide roller, load-bearing roller and guide roller are arranged on rolling wheel support, between rolling wheel support and middle hinge seat, by hinge axis, be hinged, described hinge axis is socketed with the noise reduction axle sleeve outward, and the preferred nylon of the material of described noise reduction axle sleeve forms nylon sleeve; Also be socketed with torsion spring on the noise reduction axle sleeve, one of this torsion spring is fixed on middle hinge seat, and its other end is fixed on rolling wheel support.
For the cost of production of hinge seat in reducing and rolling wheel support, the utility model provides the middle hinge seat of hinge assembly in sliding door and rolling wheel support to be the integrated punching molding structure.
Hinge assembly in the sliding door that the utility model obtains, in its structure, hinge axis is socketed with the noise reduction axle sleeve outward, torsion spring set is connected on outside above-mentioned noise reduction axle sleeve, therefore in, the angle variation occurs between the two in hinge seat and rolling wheel support, during operation for the relative rotation, torsion spring can directly not produce friction with hinge axis, therefore can effectively avoid the generation of noise, effectively promotes its functional performance; Middle hinge seat of the present utility model and rolling wheel support are the integrated punching molding structure simultaneously, so cost of production is low.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides hinge assembly in sliding door;
Fig. 2 is the partial sectional view at A-A place in Fig. 1.
In figure: middle hinge seat 1, rolling wheel support 2, hinge axis 3, torsion spring 4, noise reduction axle sleeve 5, load-bearing roller 6, guide roller 7.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As depicted in figs. 1 and 2, hinge assembly in the sliding door that the present embodiment provides, comprise middle hinge seat 1, rolling wheel support 2, load-bearing roller 6 and guide roller 7, middle hinge seat 1 and rolling wheel support 2 wherein are the integrated punching moulding, load-bearing roller 6 and guide roller 7 are arranged on rolling wheel support 2, between rolling wheel support 2 and middle hinge seat 1, by hinge axis 3, be hinged, be socketed with the noise reduction axle sleeve 5 that material is nylon outside described hinge axis 3, also be socketed with torsion spring 4 on above-mentioned noise reduction axle sleeve 5, one of this torsion spring 4 is fixed on middle hinge seat 1, its other end is fixed on rolling wheel support 2.
