Detailed Description
The present invention is described in detail below with reference to the attached drawings:
example one
As shown in fig. 1, 2, and 3, the adjustable connection device for a manual tensioning wheel includes a first plate 1 and a second plate 2, the first plate 1 and the second plate 2 are arranged in parallel at intervals according to an interval offset distance required for installation of a vehicle type to be matched, and are integrally connected through a third plate 3 (namely, a stepped bending structure is formed by stamping a flat plate), a first installation hole 11 for installation on an engine bracket or a vehicle frame and an arc hole 12 coaxial with the first installation hole 11 are machined on the first plate 1, a shape line of the arc hole 12 in this embodiment is an arc with a central angle of 36 degrees (in other preferred embodiments, other angle values meeting actual requirements), and a second installation hole 21 for installation of a tensioning wheel is machined on the second plate 2. When the manual tension wheel is installed on the air conditioner transmission pair, the manual tension wheel can be rotatably fixed on a component such as an engine bracket or a frame and the like through the first installation hole 11 by the installation bolt, then the adjustable connecting device is arranged on an engine bracket or a frame through an adjusting bolt or a nut pair and the like which pass through the arc hole 12, the position and the phase angle of the whole adjustable connecting device can be determined through the arrangement of the two points, meanwhile, a tension pulley is pre-installed on the second installation hole 21, the belt of the air conditioner transmission auxiliary gear train is tensioned through the integral position and phase angle of the adjustable connecting device during installation, and after the belt is lengthened and loosened, the adjusting bolt or the nut pair penetrating through the arc hole 12 can be unscrewed, the phase position of the adjusting bolt or the nut pair can be manually adjusted (the adjusting bolt rotates around the mounting bolt in the first mounting hole 11, the adjusting range is the circle center angle of the arc hole 12-shaped line), and the adjusting bolt or the nut pair is screwed again after the belt is tensioned again, so that the tension of the belt can meet the designed tensioning requirement again.
In this embodiment, the side of the third plate 3 is integrally connected with a fourth plate 4 formed by stamping and bending, the upper end of the fourth plate 4 includes a supporting surface 41 connected to the lower surface of the first plate 1, and the supporting surface 41 is parallel to the lower side of the first plate 1 and supports the first plate 1.
In the present embodiment, the extending direction of the supporting surface 41 is parallel to the chord of the circular arc locus of the arc hole 12 in the normal view toward the lower surface of the first plate 1. On one hand, a better stress bearing structure can be provided, namely, the stress structure (distance) of the supporting surface 41 from the first mounting hole 11 and the arc hole 12 is uniform; on the other hand, since there may be an empty space (neutral) between the first mounting hole 11 and the arc hole 12 for the purpose of being disposed on the engine mount or the vehicle frame, this arrangement can minimize the problem of interference in this empty/neutral position at the time of rotational adjustment.
In this embodiment, the fourth plate 4 is tapered from its lower end to its upper end, and its inclined oblique side is located on the opposite side of the junction of the fourth plate 4 and the third plate 3, thereby further reducing the weight while having good support performance.
In this embodiment, the joints between the first plate 1, the second plate 2, the third plate 3 and the fourth plate 4 are all arc joints to reduce stress concentration and improve bearing capacity, and these arc joints can be directly formed by a stamping die. Preferably, according to required size and different intensity, set up between 5~20mm their fillet radius and select as required.
In this embodiment, a bent reinforcing ridge 31 is formed at the circular arc connection between the second plate 2 and the third plate 3, and is orthogonal to the circular arc connection. Because the second plate 2 has the working requirement of bearing the manual tension pulley, the simple stamping bending connection may impact the second plate 2 to make it skew when bearing some lateral component force caused by the swinging of the belt, the arrangement of the reinforcing ridge 31 can effectively prevent the occurrence of such deformation, ensure the position stability of the second plate 2, and also ensure that the tension effect of the manual tension pulley can be effectively maintained.
In this embodiment, the second plate 2 further comprises a square light hole 22 (which may have other geometric shapes in other embodiments as long as the load-bearing capacity of the second plate 2 is not affected) formed by punching or cutting.
Example two
The technical solution described in the second embodiment is similar to that of the first embodiment, and the difference is that:
in this embodiment, the support surface 41 is fixedly connected to the lower surface of the first plate 1 by welding. Thereby further improving its supporting effect.
Meanwhile, as shown in fig. 2, in the present embodiment, the arc hole 12 includes a through portion 121 penetrating the first plate 1 and a counterbore portion 122 sunk from the upper surface of the first plate 1, and the contour of the counterbore portion 122 is a concentric isometric enlargement of the contour of the through portion 121. The position of the head of the adjusting bolt or the adjusting nut can be limited by the counter bore part 122 after the adjusting bolt or the adjusting nut is installed, so that the stability of the locking state after locking is improved, namely the working stability of the manual tension wheel after manual adjustment is improved.
The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the various modifications and improvements made by the ordinary person in the art without departing from the design concept of the present invention all fall into the protection scope of the present invention.
