The invention provides a four-way adjusting mechanism for a steering column. The four-way adjusting mechanism comprises an upper tubular column, a lower tubular column, a guide rail, a locking nut, an adjusting handle, a moveable cam, a locking cam, a handle shaft and a supporting bracket, wherein the guide rail is fixed on an outer wall of the upper tubular column and is provided with two brackets with long holes; the supporting bracket comprises a first lateral plate and a second lateral plate used for holding the brackets; adjusting slots are formed in the first lateral plate and the second lateral plate; the locking nut, the adjusting handle, the moveable cam and the locking cam are arranged on the outer side of the second lateral plate of the supporting bracket; the moveable cam can rotate under the driving of the adjusting handle; a buffering limiting block, a spring and a buffering supporting block are arranged between the first lateral plate and the second lateral plate of the supporting bracket; the buffering limiting block is connected with the locking cam; the spring is located between the buffering limiting block and the buffering supporting block; the handle shaft penetrates through the supporting bracket, the guide rail, the buffering supporting block, the spring, the locking cam, the moveable cam and the adjusting handle and then is connected with the locking nut.
Description
technical field [0001] The invention relates to the technical field of automobiles, and in particular to a four-way adjustment mechanism for a steering column. Background technique [0002] The steering column is an important part of the steering system of the car, and it is the steering mechanism used to connect the steering wheel and the steering gear. The steering column usually has an adjustment system for length adjustment or inclination adjustment of the steering column. However, when the length of the steering column is adjusted, there will be some small gaps between the components of the steering column adjustment system due to the influence of fitting tolerances and manufacturing tolerances. These small gaps are easily overlooked because they do not affect the basic performance and function of the steering column. However, when the adjustment system is in an adjustable state, the driver's manual adjustment of the length of the steering column will cause friction a...
