Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a variable-rigidity rear stabilizer bar, in particular to a variable-rigidity rear stabilizer bar with a bracket assembly. Background Art
[0002] Automobile suspension is an important component to ensure the ride comfort of the car. In order to improve the comfort of the car, the vertical stiffness value of the existing automobile suspension is designed to be low. Although this increases the ride comfort, when the car turns, the centrifugal force will produce a larger body tilt angle, which affects the stability of the car. In order to improve this condition, stabilizer bars are added to the front and rear suspensions of the car, and the rear lateral stabilizer bar bushing of the car connects the stabilizer bar and the body.
[0003] For example, a lateral stabilizer bar structure for a passenger car with announcement number CN217099596U and announcement date 2022.08.02 includes: a hanger assembly, a lateral stabilizer bar with a U-shaped longitudinal cross-section, and a bushing clamping mechanism, both ends of the lateral stabilizer bar are connected to the hanger assembly, so that the upper and lower ends of the hanger assembly are respectively connected to the axle and the lateral stabilizer bar; the bushing clamping mechanism is installed on the lateral side of the lateral stabilizer bar, and the upper part of the bushing clamping mechanism is welded to the frame beam, which is used to stabilize the lateral stabilizer bar in operation.
[0004] In the above-mentioned and prior art, when installing the bracket assembly, it is necessary to forcefully pry the bracket assembly apart and then put it on the outside of the stabilizer bar, and only rely on the rebound of the bracket assembly to fit the stabilizer bar. After long-term use, a gap will appear between the bracket assembly and the stabilizer bar, which has a poor support effect on the stabilizer bar and is prone to wear of the bracket assembly and the stabilizer bar. Therefore, it is urgent to design a variable stiffness rear stabilizer bar with bracket assembly to solve the above-mentioned problems. Utility Model Content
[0005] The utility model aims to provide a variable-rigidity rear stabilizer bar with a bracket assembly to solve the above-mentioned deficiencies in the prior art.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A variable-stiffness rear stabilizer bar with bracket assembly, comprising a left rod, a middle rod, a right rod, a bracket and a connecting sleeve. The outer parts of the left rod, the middle rod and the right rod are all sleeved with bracket assemblies. The bracket assembly includes an inner ring, an outer frame and an assembly block. The inner ring is arranged on the inner wall of the top of the outer frame, and the outer walls of the left rod, the middle rod and the right rod are in contact with the inner walls of the inner ring and the assembly block. Limiting blocks are arranged on the outer walls of the inner ring and the assembly block, and limiting grooves are opened inside the outer frame. The limiting blocks are clamped inside the limiting grooves. A long-neck screw is threaded through the inside of the assembly block, and the long-neck screw is threaded and inserted into the inside of the inner ring. A stop block is arranged on the outer wall of the outer frame, and the stop block is in contact with the outer wall of the inner ring. Ear plates are arranged on the outer walls of both sides of the outer frame, and mounting bolts are threaded through the inside of the ear plates.
[0008] Furthermore, support rods are arranged on the outer walls of two of the outer frames and the bracket, and reinforcing rods are arranged on the outer walls of two adjacent outer frames.
[0009] Furthermore, an oil injection pipe is inserted into the top of the outer frame, and the oil injection pipe penetrates through the inside of the limiting block and the inner ring. A pipe cap is threaded and sleeved on the top end of the oil injection pipe.
[0010] Furthermore, arc-shaped blocks are integrally connected to one ends of the left rod and the right rod, and clamping blocks are arranged at both ends of the middle rod.
[0011] Furthermore, the two arc-shaped blocks are engaged with the two clamping blocks, and the connecting sleeve is threaded and sleeved on the outside of the arc-shaped blocks and the clamping blocks.
[0012] Furthermore, cylinders are arranged at both ends of the middle rod, and the cylinders are clamped between the two arc-shaped blocks.
[0013] Furthermore, connecting pieces are arranged at the other ends of the left rod and the right rod far from the middle rod, and connecting holes are opened inside the connecting pieces.
[0014] In the above technical solution, a variable stiffness rear stabilizer bar with a bracket assembly provided by the present utility model includes a bracket assembly, an inner ring, an outer frame, a limiting block, a limiting groove, a stop block, a long-neck screw, and an assembly block. The long-neck screw threadedly penetrates through the assembly block and then threads into the interior of the inner ring until the inner ring and the inner wall of the assembly block are both in contact with the outer walls of the left rod, the middle rod, or the right rod. Then, the outer frame is fixed at the required position. In this way, even after long-term use, there will be no gaps between the bracket assembly and the outer walls of the left rod, the middle rod, and the right rod, avoiding the problem that in the existing technology, only the resilience of the bracket assembly is relied on to fit the left rod, the middle rod, and the right rod, and gaps will appear between the bracket assembly and the stabilizer bar after long-term use, and the effect of supporting and fixing the left rod, the middle rod, and the right rod is better; (2) By providing a bracket, a support rod, and a reinforcing rod, the bracket and the support rod can support the left rod and the right rod, and the reinforcing rod can strengthen the firmness between the two bracket assemblies, making the strength of the entire variable stiffness rear stabilizer bar with a bracket assembly higher; (3) By providing an arc block, a mating block, a cylinder, and a connecting sleeve, after different arc blocks are mated with the cylinder and the mating block, the threaded connecting sleeve is then threadedly sleeved outside the arc block and the mating block, and the stabilizer bar can be assembled. Since multiple stabilizer bar assemblies with different rod diameters need to be prepared before the stabilizer bar assembly is calibrated for use during the calibration process, this results in a large number of samples and inconvenient storage and transportation. The variable stiffness rear stabilizer bar is a three-section combined type and can be calibrated with each other, which is more convenient; (4) By providing an oil injection pipe and a pipe cap, lubricating oil can be added between the inner ring and the left rod, the middle rod, or the right rod through the oil injection pipe, which can reduce the wear at the contact between the inner ring and the left rod, the middle rod, or the right rod.
