Detailed description of the invention
In order to make the utility model clearly understand, describe in detail this device below in conjunction with accompanying drawing, specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
As Fig. 1, shown in Fig. 3 and Fig. 4, a kind of compression anchor fitting for automobile front suspension spring that the utility model provides, comprise support body 9, the lower swing arm 11 with its corresponding matching is equipped with in the both sides of described support body 9, described lower swing arm 11 can rotate to an angle relative to corresponding support body 9, a flange 10 is equipped with in the front side of the fore sub frame of described support body 9 both sides, be provided with below described each lower swing arm 11 one with the cylinder 13 of its corresponding matching, clamping upper plate 1 on each described flange 10, the downside of described upper plate 1 is provided with the groove 1a coordinated that to step down with described corresponding flange 10, a projection 1b is provided with in described groove 1a, projection 1b and described flange 10 snap-fit engagement.The both sides of described upper plate 1 connect a clamping band 2 and a snapping band 3 respectively, and described clamping band 2 and snapping band 3 can adopt chain, steel rope or binding strap, and this device is all preferably chain.
Described clamping band 2 also connects the side of lower plate 4, opposite side hinged cooperation Connection Block 6 of described lower plate 4, and the upper side of described lower plate 4 is provided with a slot to make way 4a, and described slot to make way 4a steps down with described lower swing arm 11 and coordinates.Described Connection Block 6 is connected one and links up with 5, described hook 5 is the bolt that a front side is provided with hook 5a, is locked after hook 5 is connected with described Connection Block 6 by jam nut 8.Hook 5 mounts with described snapping band 3 and coordinates, and described lower plate 4 is arranged on downside and its force fit of described lower swing arm 11.
Shown in composition graphs 2, the side of described Connection Block 6 is provided with a U-type groove 6a, and opposite side is provided with a screw 6c, and U-type groove 6a is coordinated with described lower plate 4 is hinged by latch 7, Connection Block 6 freely can rotate in lower plate 4, and described hook 5 to be connected with screw 6c by screw thread and to coordinate.
Force Calculation
Described spring 12 is when compressive state, and the pressure that spring 12 produces is about 0.36 ton.The elastic force of spring is: power=spring stiffness (kg/mm) * amount of compression (mm)=240N/mm*15mm=3600N=3.6KN=0.36 ton.Consider that the elastic force of this spring is comparatively strong, the pre-allowance over design of gripping power need ensure 1 ton.
The structure of whole device comprises the tensile strength that upper plate, lower plate and chain need to ensure 2 tons, and the position of bulk strength weakness is at hook bolt place.
According to the tensile strength standard of bolt, the strong 4*4*3.14*400N/MM of tension of the bolt of common M8
2=20096N namely 2 tons, so the screw thread of the bolt of described hook 5 employing should be more than or equal to M8, because this bolt is non-standard, adopts modulating treatment process, reaches tensile strength and can be reached for 2 tons.
Control step and method:
A, described lower swing arm 11 to be rotated, spring 12 is put between corresponding upper arm 10 and lower swing arm 11.
B, cylinder 13 push up on described lower swing arm 11, and spring 12 was compressed to stroke.
C, the projection 1b of upper board 1 is put into flange 10.
D, lower plate 4 is walked around lower swing arm 11 aft hook 5 be articulated on snapping band 3.
The position of e, adjustment hook 5 makes the overall length of snapping band 3 and hook 5 equal the length of clamping band 2, to utilize the installation of car load.
F, loosen cylinder 13, make spring 12 be relaxed to upper plate 1 and lower plate 4 bears pressure.
The spring of g, automobile front suspension both sides is in compressive state simultaneously, and front suspension is transported to car load fitting line place.
H, align steering swivel and shock absorber attachment hole, and be screwed into bolt and assemble.
I, car load land, and rely on vehicle body deadweight, the chain of automobile front suspension is in relaxed state, and hook 5 can take off from snapping band 3, pulls down frock by hand from tire both sides.
