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 stabilizer bar bushing 2 and the stabilizer bar bracket 3, the stabilizer bar bushing 2 is made of rubber material, and the stabilizer bar bracket 3 has a groove 31 for the stabilizer bar bushing 2 to snap into , The bottom of the stabilizer bar bushing 2 has a limit protrusion, and the groove 31 has a limit hole matching the limit protrusion, and the stabilizer bar bracket 3 is fixedly connected with the sub-frame through the connecting bolt 10 . As a preferred solution, the stabilizer bar bracket 3 and the stabilizer bar bushing 2 are respectively installed at both ends of the stabilizer bar body 1 , and the stabilizer bar body 1 has a stop plate 11 for positioning the stabilizer bar bushing 2 . By positioning the two ends of the stabilizer bar body 1, it is more conducive to the transmission of the torsional deformation of the stabilizer bar body 1, and avoids the excessive deformation of the two ends of the stabilizer bar body 1 resulting in bevel gear one 7 and bevel gear two 8 Unable to engage properly. In the actual production and manufacturing process, the stabilizer bar can also be made of other elastic metal materials.
[0031] like figure 2 and image 3As shown, the two ends of the stabilizer bar body 1 are respectively facing the lower swing arm assembly 6 at both ends of the sub-frame, and the bevel gears 1 and 7 are respectively arranged at both ends of the stabilizer bar body 1 and are aligned with the stabilizer bar body 1 axially and circumferentially. In this embodiment, the bevel gear-7 has a center hole, and the bevel gear-7 is sleeved on the stabilizer bar body 1 through the center hole. The center hole of the bevel gear-7 is processed with internal splines, and the stabilizer bar body 1 External splines are processed at both ends of the bevel gear 1, and the bevel gear 7 is connected with the stabilizer bar body 1 through the spline for circumferential positioning; the bevel gear 1 7 has a pin hole 1 opened in the radial direction, and the outer peripheral surface of the stabilizer bar body 1 There is a pin hole 2 corresponding to the position and shape of the pin hole 1, and the bevel gear 7 is inserted into the pin hole 1 and the pin hole 2 through the positioning pin to be axially positioned with the stabilizer bar body 1 .
[0032] like image 3 and Figure 4 As shown, the connecting sleeve 61 is located at the position corresponding to the two ends of the lower swing arm assembly 6 and the stabilizer bar body 1, and the connecting sleeve 61 is arranged horizontally and perpendicular to the stabilizer bar body 1. The arm assembly 6 adopts a one-piece structure. The second bevel gear 8 has a central hole, and the second bevel gear 8 is sleeved on the connecting sleeve 61 through the central hole. The mounting bolt 9 is axially positioned with the connecting sleeve 61. By positioning the bevel gear 2 8 on the ready-made connecting sleeve 61 on the lower swing arm assembly 6, the installation requirements of the bevel gear 2 8 are met, the power transmission effect is good, and the structure of the lower swing arm assembly 6 is not required. A redesign saves production costs. Such an arrangement makes the stabilizer bar device of the automobile not only able to be installed in a specially designed suspension system, but also suitable for refitting an existing suspension system, and has good versatility.
[0033] like figure 2 and Figure 5 As shown, the first bevel gear 7 and the second bevel gear 8 at the corresponding positions are meshed, and the transmission ratio of the first bevel gear 7 and the second bevel gear 8 can be selected according to actual needs. The swinging trend of the lower swing arm assembly 6 and the torsion trend of the stabilizer bar body 1 can be transmitted to each other through the cooperation of the first bevel gear 7 and the second bevel gear 8, so that the force between the lower swing arms on both sides of the vehicle body can be better transmitted to each other , Play the role of balancing the body on both sides.
[0034] The working principle of the stabilizer bar device of this car is: when the wheels on both sides of the vehicle body move vertically at the same time, the lower swing arm assembly 6 on both sides of the vehicle body swings synchronously and drives the bevel gear 2 8 to reversely rotate the same angle, and the two ends of the stabilizer bar body 1 The bevel gear-7 rotates synchronously, and the stabilizer bar body 1 rotates freely in the stabilizer bar bushing 2 without affecting the balance of the vehicle body. When the wheels on both sides of the vehicle body bounce in the opposite direction, the lower swing arm assembly 6 on both sides of the vehicle body swings in the opposite direction to drive the bevel gear 2 8 to rotate in the same direction, and the bevel gear 1 7 at both ends of the stabilizer bar body 1 rotates in the opposite direction, so that the stabilizer bar body 1 The torsion is generated to transmit the force from the lower swing arm assembly 6 on the side with greater stress to the lower swing arm assembly 6 on the side with less stress, realizing lateral stiffness compensation. Make the car maintain a better balance when turning or one side of the wheel hits an obstacle, and prevent the car from rolling over.

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.
