Description

A new kingpin caster angle adjustment mechanism with limit function for automobiles

technical field

The utility model relates to a kingpin caster angle adjustment mechanism, in particular to a new kingpin caster angle adjustment mechanism with a position limiting function for automobiles.

Background technique

The thrust rod is mainly used in the rear independent suspension of off-road vehicles, one end of which is connected to the body, and the other end is connected to the suspension. Due to the weight of the vehicle body, the assembled thrust rod is subject to the preload tension, so it is difficult to adjust it. Carry out disassembly and replacement.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a novel caster angle adjustment mechanism with a position-limiting function that is reasonable in structure and used for automobiles.

This novel kingpin caster angle adjustment mechanism with limit function for automobiles includes an upper support assembly and an adjustment plate, two first waist-shaped holes are respectively opened on both sides of the adjustment plate, and the two The first waist-shaped hole forms a symmetrical structure on both sides of the upper support assembly, and a second waist-shaped hole is opened at the center of the adjustment plate. The upper end of the upper support assembly matches the second waist-shaped hole, and can The second waist-shaped hole moves in the long side direction; the first waist-shaped hole is respectively equipped with bolts and supporting nuts and washers, and the bolts can only be moved along the long sides of the waist-shaped hole in the first waist-shaped hole. The bottom of the gasket is provided with a bump structure, and the adjustment plate is respectively provided with key grooves that can cooperate with the bump structure along the two long sides of the first waist-shaped hole.

As a preference: the key grooves are multiple evenly distributed on the two long sides of the first waist-shaped hole, and the distance between adjacent key grooves is 5mm.

As a preference: three installation through holes for fixing with the vehicle body are opened in the circumferential direction of the outer periphery of the adjustment plate.

The beneficial effect of the utility model is: the caster angle of the kingpin can be adjusted precisely through the mechanism, and the upper support has a limit function after assembly, preventing the upper support from moving after the mounting nut is loosened. The keyway acts as a limit constraint on the bump structure, preventing the nut from loosening during the movement of the vehicle, causing the installation position of the upper support to move along the direction of the waist hole.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further. Although the utility model will be described in conjunction with preferred embodiments, it should be understood that it does not mean that the utility model is limited to the embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.

As shown in Fig. 1 to Fig. 4, the novel kingpin caster angle adjustment mechanism that is used for the automobile of the present embodiment has limit function, has three through holes 14 in the circumferential direction of the adjustment plate 4, and the adjustment plate 4 is installed by bolts. Fix on the body, Figure 2, Figure 3.

The mounting holes 14 of the upper support assembly 1 on both sides of the adjustment plate 4 are designed as waist-shaped holes, and the bolts 18 can move along the waist-shaped holes 119 to drive the upper support assembly 1 to move along the waist-shaped holes 220 .

The upper surface of the adjustment plate 4 is provided with evenly distributed key grooves 13, and the lower surface of the gasket 3 is designed as a bump structure 17, and the bump structure 17 and the key groove 13 cooperate with each other.

When adjusting the inclination angle of the kingpin, loosen the nut 2, move the gasket 3 upwards, so that the protrusion structure 17 is released from the keyway 13, and turn the gasket 3 so that the protrusion structure 17 is perpendicular to the keyway 13, so as to prevent the upper support from moving When the assembly 1 is assembled, the protrusion structure 17 falls into the key groove 13 to hinder the movement of the gasket 3 . The distance between each keyway 13 is 5mm. According to the measured actual inclination value, calculate the distance that the upper support needs to move, and then divide it by 5mm, which is the number of keyways to be moved at the current position, and then install on both sides. The bolts 18 move the same keyway respectively, so that the accurate measurement of the caster angle of the kingpin can be realized. Finally, the washer 3 is rotated so that the protrusion structure 17 and the keyway 13 fit together, and the nut 2 is tightened for fixing. The keyway 13 acts as a limit constraint on the protrusion structure 17 to prevent the nut 2 from loosening during the movement of the vehicle, causing the installation position of the upper support to move along the waist-shaped hole.
