Description

Technical Field

[0001] The utility model belongs to the technical field of tie rod ball heads, and more specifically relates to a disassembly and assembly device for a tie rod ball head of an automobile. Background Art

[0002] The steering tie rod assembly is an important component of the automobile steering system and the basic connection structure for realizing the steering of the whole vehicle. It is an important component for connecting the steering drop arm with the front axle and the synchronous steering of the left and right tires.

[0003] After long-term use, the tie rod ball head will be worn out and needs to be repaired in time to ensure the normal operation of the car. Traditionally, the tie rod ball head is disassembled and assembled by manual prying, but manual prying usually causes damage to the ball head, resulting in economic losses. Later, equipment that can facilitate the disassembly and assembly of the ball head appeared on the market. For example, the patent publication number is: CN215660061U, and the patent name is a patent for a labor-saving disassembly and assembly tool for a car steering tie rod ball head. A labor-saving disassembly and assembly tool for a car steering tie rod ball head is disclosed, which relates to the technical field of automobile maintenance devices. The labor-saving disassembly and assembly tool of the automobile steering tie rod ball head includes two ball head bodies, two tie rod bodies, bolts and a bottom plate. A disassembly assembly is arranged on the top of the bottom plate. The disassembly assembly includes a cover plate, a screw rod, a first opening plate and a second opening plate. The screw rod passes through the bottom plate and is rotatably connected to the bottom plate. The screw rod is rotatably connected to the bottom of the cover plate. The thread directions of the two ends of the screw rod are set to be opposite. The first opening plate and the second opening plate are both arranged between the bottom plate and the cover plate. The screw rod passes through the first opening plate and the second opening plate and is threadedly connected to the first opening plate and the second opening plate. The labor-saving disassembly and assembly tool of the automobile steering tie rod ball head saves time and is easy to operate. At the same time, it will not cause damage to the tie rod body and the ball head body.

[0004] In the above patent, transmission is carried out through parts such as bevel gears and screw rods. In actual use, when the ball head is pried vigorously, the transmission meshing of the bevel gear is easily displaced or even damaged due to the influence of the force. At the same time, the connection of the screw rod is also easily displaced. The tool has many transmission parts and transmission failure is easy to occur. Therefore, a disassembly and assembly device for a car tie rod ball head is proposed. Utility Model Content
