Improved clamping structure for vehicle steering pipe string

Abstract

The invention relates to the technical field of automotive component manufacturing, in particular to an improved clamping structure for a vehicle steering pipe string. The improved clamping structure for the vehicle steering pipe string comprises an upper pipe string, a U-shaped frame and a handle spring, wherein the U-shaped frame is arranged in a sleeving manner outside the upper pipe string, and the handle spring penetrates the upper pipe string and the U-shaped frame from one side of the upper pipe string; an axial spring rack is arranged at the penetrating end of the handle spring in a sleeving manner, and an axial rack is fixed in front of the axial spring rack; a right radial soft retainer is arranged in front of the axial rack, a radial spring rack is arranged on the right radial soft retainer in a sleeving manner, a radial rack is arranged on the radial spring rack in a sticking manner, and a tightening nut is arranged in front of the radial rack; and both ends of the radial spring rack and the U-shaped frame are fixed by a laser welding manner. According to the improved clamping structure disclosed by the invention, the axial spring rack and the radial spring rack are adopted, so that when a handle is locked, the occurrence of a tooth-to-tooth phenomenon is avoided and deformation potential is accumulated at the same time because of deformability of the spring; and when the handle is released, the deformation potential is released and the engaged racks are bounced off, so that a driver can achieve a smooth adjustment. The improved clamping structure disclosed by the invention is simple in structure, practical, convenient, and low in processing cost.

Description

technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an improved automobile steering column clamping structure. Background technique [0002] The steering column of automobiles often adopts a rack meshing structure to improve the holding force of the steering column, and the rack structure has the advantages of good economy. However, the rack structure will produce the following two problems: first, tooth to tooth, when the rack is in a state of incomplete meshing, such as figure 1 As shown, the handle cannot be locked at this position, that is, it cannot be guaranteed that the handle can be locked at any position. The operator needs to manually adjust each time until the rack is fully engaged to lock the handle; second, when the handle is released, the engaged rack If it cannot be completely separated, the adjustment force of the steering column will become larger, the adjustment will not be smooth, and the...

However, the rack structure will produce the following two problems: first, tooth to tooth, when the rack is in a state of incomplete meshing, such as figure 1 As shown, the handle cannot be locked at this position, that is, it cannot be guaranteed that the handle can be locked at any position. The operator needs to manually adjust each time until the rack is fully engaged to lock the handle; second, when the handle is released, the engaged rack If they cannot be completely separated, the adjustment force of the steering column will become larger, the adjustment will not be smooth, and the adjustment noise will be generated.
