Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive rack with anti-slip teeth. Background Technology

[0002] A rack is a special type of gear with teeth distributed on a bar-shaped body. Racks are also divided into spur racks and helical racks, which are paired with spur gears and helical gears respectively. The main function of a car rack is to transmit the power of the steering gear to the steering tie rod, thereby realizing the vehicle's steering function.

[0003] However, the existing technology has the following drawbacks:

[0004] When a rack and pinion are used in pairs, the angle at the contact point between the rack and pinion changes when the car is turning. The smooth surface of the rack may cause the pinion to slip, affecting the transmission and making it impossible for the car to turn, thus affecting the car's driving. Utility Model Content

[0005] The purpose of this invention is to provide an automotive rack with anti-slip teeth to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car rack with anti-slip serrations, comprising a fixed base and a rack body. The fixed base includes two fixing blocks and two connecting rods. A first slot is provided in the middle of one side of the top of the fixed base, and a threaded hole is provided in the middle of the bottom inner wall of the first slot. A connecting plate is provided in the middle of both ends of the rack body. A threaded through hole is provided in the middle of the end of the connecting plate away from the rack body. The connecting plate is engaged and installed inside the first slot. A plurality of protruding teeth are evenly provided on the outer side of the rack body. A plurality of first anti-slip ridges are evenly provided on the outer walls of both sides of the protruding teeth. A plurality of second anti-slip ridges are evenly provided on the outer side of the rack body, and the second anti-slip ridges are located between two adjacent protruding teeth.

[0007] The above technical solution has multiple first anti-slip ridges and second anti-slip ridges evenly distributed on the outer wall of the rack body, which can prevent the gear and rack body from slipping during rotation, ensure that the two fit tightly together, and achieve good transmission effect.

[0008] The first anti-slip ridge cross-sectional shape and the second anti-slip ridge cross-sectional shape are both isosceles trapezoids that are narrower at the top and wider at the bottom, and the side cross-sectional shape of the convex tooth is an isosceles trapezoid.

[0009] In the above technical solution, the second anti-slip ridge is annularly wrapped around the outside of the rack body, and the surfaces of the first and second anti-slip ridges are rough.

[0010] The threaded through hole and the threaded hole are provided in correspondence, and screws are installed sequentially inside them. The two corners of the connecting plate away from the rack body are rounded and chamfered. The cross-sectional shape of the connecting plate is a rounded rectangle.

[0011] The above technical solution uses a rack body that is fixedly connected to a base via connecting plates at both ends, ensuring a secure installation and preventing it from falling off.

[0012] Each of the two fixing blocks has a second slot at the middle of one end. The two ends of the connecting rod are engaged and installed inside the second slot. A rubber pad is adhered to the inner wall of the second slot. A fixing plate is provided at the middle of the three sides of both ends of the connecting rod. One side of the fixing plate is in close contact with the side of the fixing block near the connecting rod, and the two are fixedly connected by fastening bolts.

[0013] The above technical solution features a separate design for the connecting rod and the fixing block, which are detachable. The specifications of the connecting rod can be adjusted according to different lengths and models of rack bodies.

[0014] The fixing block has a mounting hole in the middle of the side away from the connecting rod. A rotating connector is embedded in the mounting hole, and the inner cylinder of the rotating connector is fixedly installed with the connector.

[0015] In the above technical solution, the outer wall of the outer cylinder of the rotating connector is fixedly connected to the inner wall of the mounting hole, and the inner cylinder of the rotating connector is rotatably connected to the outer cylinder.

[0016] The connector includes a mounting base, one end of which is fixedly mounted with a limiting plate. Both the mounting base and the limiting plate are engaged inside the rotating connector and are fixedly connected to the inner wall of the inner cylinder of the rotating connector.

[0017] The above technical solution uses a limiting plate to prevent the connecting part from falling off due to the disconnection between the connecting part and the inner cylinder of the rotating connecting part, thus serving a limiting function.

[0018] Both ends of the mounting base away from the limiting plate are fixedly installed with clamps. A through hole is opened in the middle of both clamps. Both the mounting base and the limiting plate are cylinders. The cross-sectional diameter of the limiting plate is larger than the cross-sectional diameter of the mounting base, and the length of the mounting base is larger than the length of the limiting plate.

[0019] By adopting the above technical solution, the connecting parts at both ends of the fixed base facilitate the fixed connection between the rack body and the car frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The outer wall of the rack body and the outer wall of the rack are respectively provided with a first anti-slip ridge and a second anti-slip ridge, which play an anti-slip role, ensure a tight connection between the rack body and the gear, avoid slippage during transmission, affect vehicle driving, and improve safety performance.
