Embodiment Construction

[0026] The structure diagram of the present invention is as Figure 6 Shown: mainly includes left steering knuckle 2, left steering rod 4, left dust jacket 6, left push rod 21, left pin shaft 20, shaft 7, steering gear housing 8, right pin shaft 16, right push rod 15, Right dust jacket 9, right steering rod 11, right steering knuckle 13, cam 17 (comprising ring gear 23), steering input shaft 18 (can be processed as one with pinion 19), pinion 19 and other parts are formed.

[0027] combine Figure 6 , Figure 7 , Figure 8 , Figure 11 , The center of the cam 17 is machined to form an inner ring gear 23, which meshes with the pinion 19, and the center of the inner ring gear is rotatably connected to the steering gear housing 8 through the shaft 7. On the end face of the cam 17, an annular groove 22 is engraved on the periphery of the ring gear 23, which includes a section of left side curved groove 221 and a section of right side curved groove 222 (such as Figure 7 As sh...

Abstract

The invention discloses an automobile steering device which comprises a let steering pull rod, a right steering pull rod, a steering device shell body, a steering input shaft, a pinion, a left handspike, a right handspike and a cam, wherein, the center of the cam is provided with a ring gear whose center is rotatablely connected with the steering device shell body, and the periphery of the ring gear is provided with a left cam slot and a right cam slot. One end of the left handspike is provided with a left pin roll inserted in the left cam slot, and the other end of the handspike is hinged with the left steering pull rod; and one end of the right handspike is provided with a pin roll inserted in the right cam slot, and the other end of the handspike is hinged with the right steering pull rod. The invention makes use of a cam mechanism to cause rotation angles of the left steering wheel and the right steering wheel meet the Ackermann curve in real time, each wheel of the steering device carries out pure rolling movement when an automobile steers, and the abnormal abrasion is reduced when tyres steer, thus enhancing the life of the tyres greatly. The variable transmission ratio is realized, and the operation stability and the security are enhanced.

Description

technical field [0001] The invention relates to a mechanical automobile steering gear. Background technique [0002] The steering gear is one of the important assemblies on the car. Its main function is to change or maintain the driving direction of the car. Its performance is one of the important symbols to measure the stability of the car's handling. At present, the main structural forms used in practice are recirculating ball type and rack-and-pinion type, and the rack-and-pinion steering gear is because of its simple structure, lightness, and high operating sensitivity. It is used in various light passenger (cargo) vehicles, cars, It has been widely used in SUV and other types of cars. Usually, when the car turns left, the steering wheel on the left is called the inner wheel, and the steering wheel on the right is called the outer wheel; correspondingly, when the car turns right, the steering wheel on the right is called the inner wheel. It is the inner wheel, and the ...
