Description

Technical Field

[0001] The utility model relates to the technical field of automobile stabilizer bars, in particular to a reinforced automobile stabilizer bar. Background Art

[0002] The car stabilizer bar, also known as the lateral stabilizer bar or anti-roll bar, is an important component of the car suspension system. Its main function is to prevent the car body from excessive tilting when turning. By increasing the stiffness of the suspension system and reducing the left and right independent movement of the suspension, the stability and handling of the vehicle are improved. The stabilizer bar is usually made of spring steel and is "U" shaped. It is placed horizontally at the front and rear end of the car. The two ends are connected to the suspension guide arm through rubber pads or ball pins, and the middle part is hinged to the body or frame through rubber bushings.

[0003] The automobile stabilizer bar consists of a connecting rod made of spring steel, a bushing for connecting to the vehicle frame, a bracket for connecting to the suspension ball stud, and an anti-skid ring. The traditional stabilizer bar is fixed directly to the end of the connecting rod by bolts through the bracket. In this connection method, the bolt connection position bears all lateral forces. After long-term use, the bolts are easily damaged or stripped due to the strong lateral shear force. Therefore, it is urgent to design a reinforced automobile stabilizer bar to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a reinforced automobile stabilizer bar, in which a bracket reinforcement arm is added at the position of the bracket connecting seat, which is used to cover and sleeve the steel rod bracket. The force that the bracket is subjected to when the suspension is steering or rebounding can be directly transmitted to the spring steel rod through the bracket reinforcement arm, thereby reducing the oblique shear force borne by the screw at the bracket connecting seat, thereby improving the connection strength between the bracket and the spring steel rod, and improving the service life of the stabilizer bar and the force transmission stability.

[0005] The utility model provides a reinforced automobile stabilizer bar:

[0006] It includes a spring steel rod, both ends of which are integrally connected to a bracket connecting seat, a steel rod bracket is fixed to one side of the bracket connecting seat by a nut, and the bottom end of the bracket connecting seat is provided with a bracket reinforcement arm that is wrapped around the outer wall of the steel rod bracket, and an elastic top block is provided on the inner side of the top end of the bracket reinforcement arm close to the steel rod bracket for limiting sliding, the outer surface of the elastic top block is in contact with the outer surface of the steel rod bracket, and a guard arm frame is provided on the outside of the elastic top block, the guard arm frame is fit and sleeved on the outer surface of the steel rod bracket, and both ends of the guard arm frame are fixed to the outer wall of the bracket reinforcement arm.

[0007] Preferably, a bracket sleeve rod is fixed to the position where the bracket connecting seat is connected to the steel rod bracket, one end of the steel rod bracket connected to the bracket connecting seat is sleeved on the outside of the bracket sleeve rod, and a threaded fixing nut is sleeved on the outside of the end of the bracket sleeve rod away from the bracket connecting seat, and the side surface of the fixing nut is in contact with the outer surface of the steel rod bracket. The bracket sleeve rod and the fixing nut are used to connect the steel rod bracket, so that the stabilizing bar can be replaced with steel rod brackets of different lengths and sizes according to its own needs during actual use, thereby improving the scope of application of the device.

[0008] Preferably, a threaded hole parallel to the bracket sleeve rod is opened on the outer wall of the bracket reinforcement arm near the bracket sleeve rod, and a nut anti-slip rod is passed through the inner side of the threaded hole, and the nut anti-slip rod is threadedly screwed to the threaded hole, and one end of the nut anti-slip rod is located inside the threaded hole and is located on the outside of the side of the fixing nut facing away from the steel rod bracket. The threaded hole parallel to the bracket sleeve rod opened on the outside of the bracket reinforcement arm can allow the nut anti-slip rod to be passed through the inside, and the end of the nut anti-slip rod is extended to the outside of the bracket sleeve rod to prevent the fixing nut connected to the outside of the bracket sleeve rod from falling off, thereby avoiding the fixing nut and the bracket sleeve rod from falling off when loosening, and allowing the fixing nut to abut against the nut anti-slip rod when loosening, thereby improving the safety of use between the steel rod bracket and the bracket connecting seat.

[0009] It should be noted that the reason why there is a certain distance between the nut anti-slip rod and the bracket sleeve rod is to prevent the bracket reinforcement arm from bending due to thrust or lateral force, causing the nut anti-slip rod to collide with the bracket sleeve rod, causing vibration and affecting the fixing nut, thereby improving the connection tightness between the fixing nut and the bracket sleeve rod.

[0010] Preferably, a rebound groove is provided at the position where the bracket reinforcement arm is connected to the elastic top block, and a limiting block is fixed at one end of the elastic top block located inside the rebound groove, and the side surface of the limiting block slides on the inner surface of the rebound groove.

[0011] Preferably, symmetrical reinforcing springs are fixed on both sides of the rebound groove, and the other end of the reinforcing spring is in contact with the outer surface of the limit block. The setting of the elastic top block can make the steel rod bracket always fit in with the connection position of the bracket reinforcement arm, avoiding the occurrence of gaps and slight collisions during the transmission of force. At the same time, when the steel rod bracket is subjected to force, it can still be transmitted through the bracket reinforcement arm, reducing its own load. (It should be noted that the installation of the elastic top block allows the use of steel rod brackets of various types and sizes on the top of the bracket reinforcement arm).

[0012] Preferably, two symmetrical sets of combination screws are provided at the position where the guard arm frame is connected to the bracket reinforcement arm, and the combination screws are threadedly fixed inside the bracket reinforcement arm. The guard arm frame is fixed with the combination screws, which can facilitate the connection operation of the steel rod bracket during installation, and allows the bracket reinforcement arm to be replaced with steel rod brackets of various sizes.

[0013] Compared with the related art, the reinforced automobile stabilizer bar provided by the present invention has the following beneficial effects:

[0014] The utility model adds a bracket reinforcement arm at the position of the bracket connecting seat, which can directly transmit the force that the bracket is subjected to when the suspension is turned or rebounded to the spring steel rod through the bracket reinforcement arm, reducing the oblique shear force borne by the screw at the position of the bracket connecting seat, thereby improving the connection strength between the bracket and the spring steel rod, and improving the service life of the stabilizer bar and the force transmission stability.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0022] Please see the attached Figures 1-4The embodiment of the present invention provides a reinforced automobile stabilizer bar, which comprises:

[0023] The spring steel rod 1 is made of spring steel and has super elastic force. The two ends of the spring steel rod 1 are integrally connected with a bracket connecting seat 2. The bracket connecting seat 2 can be used to connect with the bracket to bear the lateral force transmitted by the bracket to the spring steel rod 1, and at the same time bear the shear force between the bracket and the bracket when the bracket transmits the lateral force.

[0024] A bracket sleeve rod 7 is connected to one side of the bracket connecting seat 2, and a steel rod bracket 3 is sleeved on the outside of the bracket sleeve rod 7. A fixing nut 8 is sleeved on the end of the bracket sleeve rod 7, and the fixing nut 8 can fix the steel rod bracket 3 connected to the outside of the bracket sleeve rod 7.

[0025] A bracket reinforcement arm 4 is provided at the bottom of the bracket connecting seat 2. The bracket reinforcement arm 4 itself is designed to be hook-shaped and can be wrapped around the steel rod bracket 3 connected to the side of the bracket connecting seat 2. A guard arm frame 6 is connected to the top of the bracket reinforcement arm 4 close to the steel rod bracket 3. The guard arm frame 6 is fitted on the outer surface of the steel rod bracket 3. Through the fitting connection between the guard arm frame 6 and the steel rod bracket 3, when the steel rod bracket 3 is subjected to lateral force, the force can be first transmitted to the bracket reinforcement arm 4, and the bracket reinforcement arm 4 is used to directly transmit the force to the spring steel rod 1, thereby reducing the pressure on the bottom of the steel rod bracket 3 and the bracket connecting seat 2, thereby improving the connection strength between the bracket connecting seat 2 and the steel rod bracket 3 and increasing the service life.

[0026] There is an elastic top block 5 sliding on the inner side of the position where the bracket reinforcement arm 4 is connected to the guard arm frame 6. Through the setting of the elastic top block 5, when the spring steel rod 1 transmits reverse force to the steel rod bracket 3, the super elastic force of the elastic top block 5 can be used to transmit the force through the bracket reinforcement arm 4 to the upper part of the steel rod bracket 3, thereby reducing the pressure at the connection position between the bottom of the steel rod bracket 3 and the bracket connecting seat 2.

[0027] It should be noted that the reason why the arm guard frame 6 is not directly fixed to the steel rod bracket 3 in a completely fitted manner but the elastic top block 5 is used is that the position of the bracket reinforcement arm 4 can be equipped with steel rod brackets 3 of various shapes or sizes for installation and use.

[0028] Usage process:

[0029] Remove the fixing nut 8 on the outside of the bracket sleeve rod 7, sleeve one end of the steel rod bracket 3 on the outside of the bracket sleeve rod 7, and fix the steel rod bracket 3 with the fixing nut 8. Then sleeve the arm guard frame 6 on the top of the bracket reinforcement arm 4 on the outside of the steel rod bracket 3, and use the combination screw 14 to fix the arm guard frame 6 and the bracket reinforcement arm 4 to complete the sleeve connection between the steel rod bracket 3 and the bracket reinforcement arm 4. At this time, the outer surface of the steel rod bracket 3 will fit with the arm guard frame 6 and the elastic top block 5. When the steel rod bracket 3 is subjected to lateral force, it will be directly transmitted to the spring steel rod 1 through the bracket reinforcement arm 4.

[0030] It should be noted that the bracket reinforcement arm 4 is made of spring steel.

[0031] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0032] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
