Example Embodiment

[0028] Embodiment one:

[0029] The stabilizer bar device of the automobile is arranged between the auxiliary vehicle body and the lower swing arm assembly 6, and is used to realize the balance effect on both sides of the automobile body when the automobile is running or turning. like image 3 As shown, the lower swing arm assembly 6 has a mounting hole 1 62 and a mounting hole 2 63. The mounting hole 1 62 and the mounting hole 63 are respectively connected to the sub-frame through mounting screws. The lower swing arm assembly 6 can be connected to the sub-frame. swing. The stabilizer bar device of this automobile comprises stabilizer bar body 1, stabilizer bar bushing 2, stabilizer bar support 3, bevel gear one 7 and bevel gear two 8.

[0030] Specifically, as figure 2 and image 3 As shown, the stabilizer bar body 1 is a straight rod, and in this embodiment, the stabilizer bar is made of spring steel. The stabilizer bar body 1 is installed on the sub-frame through the ...

Example Embodiment

[0035] Embodiment two:

[0036] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the bevel gear 7 has a central hole, and the bevel gear 7 is sleeved on the stabilizer bar body 1 through the central hole. The center hole is provided with a card slot along the circumference, and the outer surface of the stabilizer bar body 1 has a buckle that matches the card slot. The bevel gear 7 passes the buckle and the card The groove fits with the axial positioning of the stabilizer bar body 1 . When assembling, the internal spline in the central hole of the bevel gear 7 cooperates with the external spline at the end of the stabilizer bar body 1. When the bevel gear 1 7 moves axially to the designed position, the buckle on the stabilizer bar body 1 snaps into place. In the draw-in groove on the bevel gear, the bevel gear one 7 and the stabilizer bar body 1 are positioned.

Abstract

The invention provides a stabilizer bar device of an automobile, and belongs to the technical field of automobiles. The stabilizer bar device solves the problems that an existing stabilizer bar device of the automobile is low in transmission efficiency and high in energy loss. The stabilizer bar device comprises a stabilizer bar body, a stabilizer bar support and a stabilizer bar lining, the stabilizer bar body is installed on an auxiliary frame through the stabilizer bar lining and the stabilizer bar support, the stabilizer bar body is a straight bar, the two ends of the stabilizer bar body directly face lower swing arm assemblies at the two ends of the auxiliary frame in position, bevel gears I are arranged at the two ends of the stabilizer bar body, the bevel gears I and the stabilizer bar body are positioned axially and circumferentially, the positions, corresponding to the two ends of the stabilizer bar body, of the lower swing arm assemblies are provided with connecting sleeves, the connecting sleeves are horizontally arranged and are perpendicular to the stabilizer bar body, each connecting sleeve is provided with a bevel gear II capable of being meshed with the bevel gear I at the corresponding position, and the bevel gears II and the connecting sleeves are positioned axially and circumferentially. The stabilizer bar device of the automobile is high in force transmission efficiency and good in balancing performance.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a stabilizer bar device for automobiles. Background technique [0002] The car stabilizer bar device is set between the sub-frame and the suspension of the car to balance the car body and prevent the car body from excessive lateral roll when turning. like figure 1 As shown, the common automobile stabilizer bar device uses the stabilizer bar connecting rod 4 to connect the stabilizer bar body 1 with the strut assembly. The stabilizer bar bushing 2 and the stabilizer bar bracket 3 are installed on the subframe. [0003] The shape of the existing stabilizer bar body is "U" shape, for example, a kind of car suspension stabilizer bar structure disclosed in Chinese patent [Patent No. Symmetrical curved shape, the end of which is provided with a stabilizer bar joint, the middle section is the middle straight part of the stabilizer bar, through which the middle straight part of the s...
