In order to prevent the adjustment work from being easily performed by a general fastener adjusting tool, the present invention does not use the eccentric bolt to connect the trailing arm 100 and the longitudinal beam 300, but uses a general fastener 500, such as a general bolt, to connect, so that the pallet 110 cannot be moved by rotating the fastener 500 when only the general fastener adjusting tool is used. Therefore, the utility model discloses an adjustment tool 200 realizes above-mentioned adjustment work: firstly, the sleeve 220 can be sleeved on the outer side of the fastener 500, at this time, the fastener 500 is not completely screwed, then the pushing member 230 is driven to move relative to the sleeve 220, the pushing member 230 applies a pushing force to the stress plate 120, and the stress plate 120 drives the supporting plate 110 to move along the length direction of the elongated hole 130 after receiving the pushing force, so that the supporting plate 110 moves. Therefore, the utility model discloses a chassis suspension must adopt the utility model discloses specific adjustment tool 200 just can adjust the aforesaid of trailing arm 100, and only need provide this adjustment tool 200 to the 4S shop that the host computer factory corresponds, can make other vapour shops except 4S shop unable to adjust trailing arm 100 to prevent that non-professional 4S shop from leading to tire wearing and tearing, eating the problem of child because of the misadjustment.

In order to make the supporting plate 110 move accurately along the length direction of the elongated hole 130 without rotating and changing the moving direction under the driving of external force, the number of the elongated holes 130 is at least two and parallel to each other, so that under the condition that the fasteners 500 are all arranged in at least two elongated holes 130, the external force applied to the supporting plate 110 can be driven by the external force to move accurately along the length direction of the elongated hole 130 as long as the external force is not completely perpendicular to the length direction of the elongated hole 130, in other words, the elongated holes 130 act like a guide rail, and the fasteners 500 act like a slider, the guide rail is driven to move relative to the slider under the condition that the slider is fixed.

In some vehicle models, the mounting bracket 400 is mounted on the lower surface of the side member 300, which occupies the longitudinal space of the vehicle, and thus requires the trunk space of the vehicle to be compressed to achieve the minimum ground clearance requirement of the chassis, while the trunk space is too small to meet the requirements of consumers. To this end, in an embodiment of the present invention, the longitudinal beam 300 includes a recess, the mounting bracket 400 includes a bracket main body 410 and a mounting surface 420 connected to the bracket main body 410, the bracket main body 410 is disposed in the recess such that the mounting surface 420 is located in the recess, and the plurality of fastening caps 430 are fixedly disposed on the mounting surface 420. It should be noted that the mounting surface 420 being in the recess means that the mounting surface 420 does not protrude from the opening of the recess, and therefore, the mounting surface 420 may be completely in the recess or flush with the opening of the recess. Because the mounting surface 420 is located in the recess, the mounting bracket 400 does not occupy the longitudinal space of the vehicle, thereby eliminating the need to compress the trunk space of the vehicle.

In the prior art, when the vehicle is running, the contact surface between the trailing arm and the mounting surface of the mounting bracket is substantially parallel to the ground, so when the vehicle brakes, the braking force in the horizontal direction can directly act on the trailing arm, so that the trailing arm is easily dislocated relative to the mounting surface. Specifically, an acute angle θ formed between the mounting surface 420 and the horizontal plane is 10 to 30 °. Therefore, the horizontal braking force F does not completely act on the contact surface between the pallet 110 and the mounting surface 420, and the acting force F parallel to the contact surface is F × Cos θ, that is, the acting force F is smaller than the horizontal braking force F, that is, the force received by the contact surface between the pallet 110 and the mounting surface 420 is reduced, so that the pallet 110 is less likely to be dislocated with respect to the mounting surface 420, and the mounting is more reliable.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
