為了使本實用新型所解決的技術問題、技術方案及有益效果更加清楚明白,以下結合附圖及實施方式,對本實用新型進行進一步詳細說明。應當理解,此處所描述的具體實施方式僅僅用以解釋本實用新型,並不用於限定本實用新型。
如第2圖和第3圖所示,本實用新型一種實施方式的轉向橫拉杆,包括:冷拉管1、兩個球頭2、兩個卡箍3和兩個分別使兩個卡箍3緊縮的緊固件,每個球頭2包括設有外螺紋的第二轉軸201,所述冷拉管1的每一端都設有與所述外螺紋相適配的第一螺紋孔101和沿冷拉管1的軸向延伸的壓緊槽102,所述兩個第二轉軸201通過內外螺紋的配合分別安裝到兩個第一螺紋孔101中,兩個卡箍3分別套設在冷拉管1的兩端並通過所述緊固件壓緊冷拉管1,其中,所述冷拉管1上還設有與所述壓緊槽102數量相等的定位凹陷部103,各定位凹陷部103分別與各壓緊槽102相交,所述兩個緊固件分別卡在兩個定位凹陷部103中。
優選地,各定位凹陷部103分別與各壓緊槽102垂直相交。
卡箍是一種現有部件,通常用來夾緊需要被夾緊的部件。本實施方式中,每個緊固件包括螺栓4和螺母5,每個卡箍3上設有一個非閉合圓孔301和兩個同軸的安裝孔302,兩個安裝孔302都是光孔。使用時,卡箍3套設在冷拉管1上,螺栓4穿過兩個安裝孔302,螺母5套設在螺栓4的位於兩個安裝孔302之外的部分上,擰緊螺母5,非閉合圓孔301收縮變小,夾緊冷拉管1,使冷拉管1與第二轉軸201之間的結合更緊密,避免在車輛運行的過程中冷拉管1與第二轉軸201相對轉動,避免第二轉軸201從冷拉管1中脫出。在另外的實施方式中,可以將兩個安裝孔302中的一個設置為光孔,另一個設置為螺紋孔,這樣就不用設置螺母,螺栓4穿過兩個安裝孔302,擰緊螺栓4即可使非閉合圓孔301收縮變小。為了增強螺栓4和螺母5之間的緊固效果,還設有彈性墊圈6,彈性墊圈6套設在螺栓4上並位於螺母5和卡箍3之間。
優選地,所述螺栓4的軸線與冷拉管1的軸線垂直。這樣可以使冷拉管1的受力效果更好,使冷拉管1與第二轉軸201之間的結合更緊密。
所述定位凹陷部103的作用是使螺栓4能卡入其中,以此實現螺栓4和卡箍3在冷拉管1上的定位,因此,無論定位凹陷部103的形狀如何,只要能使螺栓4卡入其中即可。優選地,從所述螺栓4的軸向看,所述定位凹陷部103的輪廓為圓弧,這樣是為了方便定位凹陷部103的加工,加工時,可用銑刀直接加工出定位凹陷部103,工藝簡單,不需要特殊的加工設備。
優選地,所述圓弧的半徑大於或等於所述螺栓4的卡在定位凹陷部103中的部分的半徑。這樣是為了使螺栓4更好地卡入定位凹陷部103中。
冷拉管1的每一端的壓緊槽102可設置一個,也可設置多個,當然,若壓緊槽102較多,則相應的,定位凹陷部103也較多,這樣會影響冷拉管1的強度,因此,壓緊槽102不宜過多。優選地,冷拉管1的每一端設有兩個壓緊槽102,每一端的兩個壓緊槽102位於冷拉管1的圓周方向上相隔180度的位置,由於壓緊槽102為兩個,定位凹陷部103也為兩個,且兩個定位凹陷部103在冷拉管1圓周方向上的分佈較均勻,因此壓緊槽102和定位凹陷部103不會對冷拉管1的強度造成很大影響,即冷拉管1仍然有較好的強度,同時,由於定位凹陷部103有兩個,因此每個卡箍3在冷拉管1圓周方向上有兩個安裝位置,當卡箍3在一個安裝位置上與其他部件(如左轉向梯形臂或右轉向梯形臂)產生干涉時,可將卡箍3移到另一個安裝位置以避免與其他部件的干涉。
以上所述僅為本實用新型的較佳實施方式而已,並不用以限制本實用新型,凡在本實用新型的精神和原則之內所作的任何修改、等同替換和改進等,均應包含在本實用新型的保護範圍之內。
In order to make the technical problems, technical solutions and beneficial effects of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in FIG. 2 and FIG. 3, the steering tie rod of one embodiment of the present invention comprises: a cold drawn tube 1, two ball heads 2, two clamps 3 and two respectively for two clamps 3 a tightening fastener, each ball head 2 comprising a second rotating shaft 201 provided with an external thread, each end of the cold drawing tube 1 being provided with a first threaded hole 101 adapted to the external thread and along the cold An axially extending pressing groove 102 of the pull tube 1 , the two second rotating shafts 201 are respectively mounted into the two first threaded holes 101 by the cooperation of the internal and external threads, and the two clamps 3 are respectively sleeved on the cold drawing tube The two ends of the first and the fasteners 1 are pressed by the fasteners, wherein the cold-drawn tube 1 is further provided with a positioning recess 103 equal to the number of the pressing grooves 102, and the positioning recesses 103 are respectively Intersecting with each of the pressing grooves 102, the two fasteners are respectively caught in the two positioning recesses 103.
Preferably, each of the positioning recesses 103 respectively intersects each of the pressing grooves 102 perpendicularly.
Clamps are an existing component that is commonly used to grip components that need to be clamped. In this embodiment, each of the fasteners includes a bolt 4 and a nut 5, and each of the clamps 3 is provided with a non-closed circular hole 301 and two coaxial mounting holes 302. Both of the mounting holes 302 are optical holes. In use, the clamp 3 is sleeved on the cold drawing tube 1, the bolt 4 passes through the two mounting holes 302, and the nut 5 is sleeved on the portion of the bolt 4 outside the two mounting holes 302, and the nut 5 is tightened. The closed circular hole 301 shrinks and becomes smaller, and the cold drawing tube 1 is clamped to make the combination between the cold drawing tube 1 and the second rotating shaft 201 tighter, so as to avoid relative rotation between the cold drawing tube 1 and the second rotating shaft 201 during the running of the vehicle. The second rotating shaft 201 is prevented from coming out of the cold drawing tube 1. In another embodiment, one of the two mounting holes 302 may be provided as a light hole, and the other may be provided as a threaded hole, so that no nut is provided, the bolt 4 passes through the two mounting holes 302, and the bolt 4 can be tightened. The contraction of the non-closed circular hole 301 is made smaller. In order to enhance the fastening effect between the bolt 4 and the nut 5, a resilient washer 6 is also provided, which is sleeved on the bolt 4 and located between the nut 5 and the clamp 3.
Preferably, the axis of the bolt 4 is perpendicular to the axis of the cold drawn tube 1. This makes the force of the cold drawing tube 1 better, and the bonding between the cold drawing tube 1 and the second rotating shaft 201 is closer.
The positioning recess 103 functions to enable the bolt 4 to be engaged therein, thereby realizing the positioning of the bolt 4 and the clamp 3 on the cold drawing tube 1, and therefore, regardless of the shape of the positioning recess 103, the bolt can be made 4 can be inserted into it. Preferably, the contour of the positioning recess 103 is a circular arc when viewed from the axial direction of the bolt 4, so that the positioning of the recessed portion 103 can be directly processed by the milling cutter during processing. The process is simple and does not require special processing equipment.
Preferably, the radius of the circular arc is greater than or equal to the radius of the portion of the bolt 4 that is caught in the positioning recess 103. This is to make the bolt 4 better fit into the positioning recess 103.
The pressing groove 102 at each end of the cold drawing tube 1 may be provided one or more. Of course, if there are more pressing grooves 102, correspondingly, there are more positioning concave portions 103, which may affect the cold drawing tube. The strength of 1 is therefore not suitable for the pressing groove 102. Preferably, each end of the cold drawing tube 1 is provided with two pressing grooves 102, and the two pressing grooves 102 at each end are located 180 degrees apart in the circumferential direction of the cold drawing tube 1, since the pressing groove 102 is two There are also two positioning recesses 103, and the two positioning recesses 103 are evenly distributed in the circumferential direction of the cold drawn tube 1, so that the pressing groove 102 and the positioning recess 103 do not affect the strength of the cold drawn tube 1. A great influence is exerted, that is, the cold drawn tube 1 still has better strength. At the same time, since there are two positioning recesses 103, each of the clamps 3 has two mounting positions in the circumferential direction of the cold drawn tube 1, when the card When the hoop 3 interferes with other components (such as a left turn trapezoidal arm or a right turn trapezoidal arm) in one mounting position, the clamp 3 can be moved to another mounting position to avoid interference with other components.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention.
