Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a connection structure for a semi-separable steering rack tie rod. Background Technology

[0002] In the structure of an automotive steering system, the rack and tie rod ball joint are directly assembled together via threaded holes. During the production and assembly process, the rack and tie rod ball joint have high tightening torque requirements, and there is a possibility that the rack and tie rod ball joint may not be properly tightened.

[0003] Therefore, it is necessary to design a semi-separable steering rack tie rod connection structure to simplify and reduce the assembly difficulty of the rack and tie rod ball seat, and solve the problem of incomplete tightening that may occur during the assembly process. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a semi-separable steering rack tie rod connection structure to simplify and reduce the assembly difficulty of the rack and tie rod ball seat, and solve the problem of inadequate tightening that may occur during the assembly process.

[0005] To achieve the above objectives, this utility model provides a semi-separable steering rack and pinion connection structure, including a rack, a tie rod ball seat, and fasteners. A positioning groove is provided in the center of the tail of the rack, and a boss is provided on one side of the tail. A positioning block is provided at the head of the tie rod ball seat, with the end of the positioning block inserted into the positioning groove. The other side of the tail of the rack is inserted into the notch at the end of the positioning block. A horizontally arranged guide plane is provided at the connection between the positioning block and the tie rod ball seat. The guide plane and the end face of the tie rod ball seat respectively abut against the two sides of the boss. After passing through the positioning block, the fastener is fixed to the boss.

[0006] The fasteners include bolts and pins.

[0007] The axial direction of the fastener is perpendicular to the axial direction of the rack.

[0008] The positioning block and the pull rod ball seat are an integral structure.

[0009] The boss and rack are an integral structure.

[0010] Compared with the prior art, this utility model achieves planar guidance and positioning through the cooperation of rack and pinion and tie rod ball seat, and fixes rack and pinion and tie rod ball seat through connector, which simplifies the installation process, reduces assembly difficulty, and facilitates subsequent disassembly and maintenance. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] The present invention will now be further described with reference to the accompanying drawings.

[0013] See Figure 1 This utility model is a semi-separable steering rack and pinion connection structure, including a rack, a tie rod ball seat, and fasteners. The rack 1 has a positioning groove 11 in the center of its tail and a boss 12 on one side of its tail. The tie rod ball seat 2 has a positioning block 21 at its head. The end of the positioning block 21 is inserted into the positioning groove 11, and the other side of the tail of the rack 1 is inserted into the notch at the end of the positioning block 21. A horizontally arranged guide plane 211 is provided at the connection between the positioning block 21 and the tie rod ball seat 2. The guide plane 211 and the end face of the tie rod ball seat 2 respectively abut against the two sides of the boss 12. After the fastener 3 passes through the positioning block 21, it is fixed to the boss 12.

[0014] Fastener 3 includes bolts and pins.

[0015] To ensure the connection between the positioning block 21 and the boss 12, the axial direction of the fastener 3 is perpendicular to the axial direction of the rack 1.

[0016] To ensure connection strength, the positioning block 21 and the tie rod ball seat 2 are integral structures. The boss 12 and the rack 1 are integral structures.

[0017] During installation, the rack 1 and the tie rod ball seat 2 are guided by a guide plane 211. After the positioning block 21 at the head of the tie rod ball seat 2 is fully inserted into the positioning groove 11 of the rack 1, the tie rod ball seat 2 is pushed forward until the notch of the positioning block 21 abuts against the rack 1, thus completing the positioning in directions other than the axial direction of the rack 1. After the fastener 3 is inserted and the positioning block 21 is fixed to the boss 12, the positioning in the axial direction of the rack is completed. This invention reduces the assembly requirements of the rack 1 and the tie rod ball seat 2. The tie rod ball seat 2 is not limited by installation tools; only the tools are needed to install the final positioning fastener 3, greatly reducing the assembly difficulty.

[0018] This invention achieves planar guidance and positioning through the cooperation of a rack and pinion and a tie rod ball seat. The rack and pinion are fixed together by a connector, which simplifies the installation process, reduces the assembly difficulty, and facilitates subsequent disassembly and maintenance.
