Description

Technical Field

[0001] The utility model belongs to the technical field of automotive parts and relates to a lower fixing clamp block. Background Art

[0002] In order to achieve the steering of an automobile, a steering system is provided in the automobile, which includes a steering gear, a steering shaft, a tie rod, a stabilizer bar, a steering arm, etc. One end of the stabilizer bar is connected to the front axle through a fixing bracket, and the other end of the stabilizer bar is connected to the vehicle frame through a suspension arm assembly. The fixing bracket is also called a lower fixing clamp block. The longitudinal and transverse components of the automobile steering system must maintain spatial stability, otherwise interference will occur, resulting in the inability of the two front wheels to synchronously steer and travel in the same direction. The lower fixing clamp block is to ensure that the space between the longitudinal and transverse components of the front axle of the automobile is in a stable and reliable position, so as to ensure that the two front wheels of the automobile steer and travel in the same direction at the same pace.

[0003] For example, a kind of fixing bracket for a transverse stabilizer bar disclosed in the Chinese patent literature [Application No.: CN201621403545.8, Publication No.: CN206579437 U] includes a transverse component and two longitudinal components. The fixing bracket is integrally Π-shaped; both ends of the transverse component are provided with first through holes for installing U-shaped bolts, and second through holes are provided on both longitudinal components. The two second through holes are coaxially arranged, and the axis of the second through hole is perpendicular to the axis of the first through hole. During installation, the transverse component is fixed to the front axle by using a U-shaped bolt and the first through hole, and the longitudinal component is connected to the suspension arm assembly by using a bolt and the second through hole. When the steering system works, the stress at the connection between the transverse and longitudinal components of the fixing bracket is the greatest, and cracks, deformation or even fracture are likely to occur. When the structure of the fixing bracket changes or is damaged, it will affect the consistency of the steering pace and driving direction of the two front wheels. Summary of the Utility Model

[0004] The purpose of the present utility model is to propose a lower fixing clamp block for the above problems existing in the prior art, and the technical problem to be solved is how to improve the structural stability of the lower fixing clamp block.

[0005] The purpose of the present utility model can be achieved by the following technical solutions:

[0006] A lower fixing clamp block includes two sleeves and a cross beam connected between the two sleeves. Both ends of the cross beam are connected with longitudinal arms. The two longitudinal arms face the same direction and are respectively connected to the two sleeves. The feature is that each outer side surface of the longitudinal arm has an inclined surface extending to the corresponding sleeve. The distance between the inclined surface and the inner side surface of the longitudinal arm on the same longitudinal arm gradually increases along the direction approaching the cross beam. Each inclined surface has a protruding convex plate, and each convex plate is connected to the corresponding sleeve.

[0007] The side of each longitudinal arm facing away from the other longitudinal arm is the outer side of the longitudinal arm, the side of each longitudinal arm facing the other longitudinal arm is the inner side of the longitudinal arm, and the other two sides of each longitudinal arm are the front side and the back side of the longitudinal arm respectively. The width of the longitudinal arm is the distance between the outer side and the inner side of the longitudinal arm, and the thickness of the longitudinal arm is the distance between the front side and the back side of the longitudinal arm. The two sleeves and the cross beam form the transverse components of the lower fixing clamp.

[0008] The setting of the inclined surface increases the width of the longitudinal arm near one end of the cross beam, improving the structural strength of the connection end between the longitudinal arm and the transverse component; the setting of the convex plate forms a support between the inclined surface and the sleeve, improving the structural strength of the connection between the longitudinal arm and the transverse component. Therefore, the structural stability of the present lower fixing clamp is improved.

[0009] In the above-mentioned lower fixing clamp, the outer side of each convex plate is tangent to the outer side of the corresponding sleeve. This can reduce the stress mutation at the connection between the convex plate and the sleeve, which is beneficial to improving the structural stability of the lower fixing clamp.

[0010] In the above-mentioned lower fixing clamp, there is an arc transition between each inclined surface and the outer side of the corresponding sleeve. This can reduce the stress mutation at the connection between the inclined surface and the sleeve, which is beneficial to improving the structural stability of the lower fixing clamp.

[0011] In the above-mentioned lower fixing clamp, one end of each convex plate facing away from the sleeve is connected to the outer side of the corresponding longitudinal arm. This can increase the structural strength of the convex plate, thereby improving the structural stability of the lower fixing clamp.

[0012] In the above-mentioned lower fixing clamp, the front side and the back side of each longitudinal arm are both flat and parallel. This can make the longitudinal arm evenly arranged in terms of thickness, thereby avoiding the formation of weak structural points at the longitudinal arm near the transverse component, ensuring the structural strength of the connection between the longitudinal arm and the transverse component, and being beneficial to improving the structural stability of the lower fixing clamp.

[0013] In the above-mentioned lower fixing clamp, the wall thickness of each sleeve near the cross beam is greater than the wall thickness of the sleeve away from the cross beam. This can ensure the structural strength of the connection between the cross beam and the sleeve, which is beneficial to improving the structural stability of the lower fixing clamp.

[0014] In the above-mentioned lower fixing clamp, the cross beam has a protruding rib, and both ends of the rib are respectively connected to the two longitudinal arms. The rib not only functions as a reinforcing rib to improve the structural strength of the cross beam, but also can further improve the structural strength of the connection between the cross beam and the longitudinal beam, thereby improving the structural stability of the lower fixing clamp.

[0015] Compared with the prior art, the present utility model has the following advantages:

[0016] An inclined surface is provided on the outer side surface of the longitudinal arm, increasing the width at the connection between the longitudinal arm and the transverse member, enhancing the structural strength of the longitudinal arm. Meanwhile, a convex plate is provided on the inclined surface, forming a support between the inclined surface and the sleeve, improving the structural strength at the connection between the longitudinal arm and the transverse member, thereby enhancing the structural stability of the lower fixing clamp block.

[0022] As Figure 1 shown, a lower fixing clamp block includes two sleeves 1 and a cross beam 2 connected between the two sleeves 1. Vertical longitudinal arms 3 are connected to both ends of the cross beam 2. The two longitudinal arms 3 face the same direction and are respectively connected to the two sleeves 1. The inner hole of the sleeve 1 is perpendicular to the cross beam 2 and perpendicular to the longitudinal arm 3. The wall thickness of each sleeve 1 near the cross beam 2 is greater than the wall thickness of the sleeve 1 away from the cross beam 2. The side of each longitudinal arm 3 facing away from the other longitudinal arm 3 is the outer side surface of the longitudinal arm 3, the side of each longitudinal arm 3 facing the other longitudinal arm 3 is the inner side surface of the longitudinal arm 3, and the other two sides of each longitudinal arm 3 are the front and back surfaces of the longitudinal arm 3 respectively. The thickness of the longitudinal arm 3 is the distance between the front and back surfaces of the longitudinal arm 3, and the width of the longitudinal arm 3 is the distance between the outer side surface and the inner side surface of the longitudinal arm 3. The wall thickness of the sleeve 1 is the distance between the outer side surface and the inner side surface of the sleeve 1. The two sleeves 1 and the cross beam 2 form the transverse member of the lower fixing clamp block. The lower fixing clamp block is integrally cast from a metal material and is a symmetric structure.

[0023] Combined with Figure 2 and Figure 3As shown, an inclined surface 3a extending to the corresponding sleeve 1 is provided on the outer side surface of each longitudinal arm 3. On the same longitudinal arm 3, the distance between the inclined surface 3a and the inner side surface of the longitudinal arm 3 gradually increases along the direction close to the cross beam 2. An arc transition is provided between each inclined surface 3a and the outer side surface of the corresponding sleeve 1. A protruding convex plate 4 is provided on each inclined surface 3a, and each convex plate 4 is connected to the corresponding sleeve 1. The outer side surface of each convex plate 4 is tangent to the outer side surface of the corresponding sleeve 1. One end of each convex plate 4 facing away from the sleeve 1 is connected to the outer side surface of the corresponding longitudinal arm 3. The front and back surfaces of each longitudinal arm 3 are both flat and parallel, so that the longitudinal arm 3 is uniformly arranged in thickness. A protruding rib 5 is provided on the cross beam 2, and both ends of the rib 5 are respectively connected to the two longitudinal arms 3. A through hole 3b is provided on each longitudinal arm 3, and the through hole 3b is located below the convex plate 4, and the two through holes 3b are coaxially arranged.

[0024] The setting of the inclined surface 3a increases the width of the longitudinal arm 3 near the cross beam 2, improving the structural strength of the end of the longitudinal arm 3 connected to the transverse member; the setting of the convex plate 4 forms a support between the inclined surface 3a and the sleeve 1, improving the structural strength of the connection between the longitudinal arm 3 and the transverse member. Therefore, the lower fixing clamp block improves the stability of the structure.
