Embodiment Construction

[0010] exist figure 1 Among them, the steering gear 1, the output shaft 3, the drop arm sleeve 2, the drop arm 6, the washer 4, and the nut 5 are sequentially connected, the outer spline of the output shaft 3 is connected with the inner spline of the drop arm sleeve 2, and the drop arm sleeve 2 The outer splines are connected with the inner splines of the drop arm 6, and the difference between the number of teeth of the inner and outer splines of the drop arm sleeve 2 is 1 or more. When the angular position of the drop arm 6 needs to be adjusted, the drop arm cover 2 and the drop arm 6 can be rotated separately or simultaneously. The adjustment angle of the drop arm 6 is equal to the sum of the rotation angle of the drop arm cover 2 and the rotation angle of the drop arm 6. Turn 1 tooth in the opposite direction with the vertical arm 6, and the rotation angle of the vertical arm 6 is the adjustment accuracy of the vertical arm 6, which is much higher than the adjustment accura...

Abstract

The invention provides a connecting device of a steering gear plumbing arm. A steering gear, an output shaft, a plumbing arm sleeve, a plumbing arm, a gasket and a nut are sequentially connected; an outer spline of the output shaft is connected with an inner spline of the plumbing arm sleeve; an outer spline of the plumbing arm sleeve is connected with an inner spline of the plumbing arm; and the quantities of teeth of the inner and outer splines of the plumbing arm sleeve are different. When the position of the plumbing arm is adjusted, the plumbing arm sleeve and the plumbing arm can be respectively or simultaneously rotated; an adjusting angle of the plumbing arm is the sum of a rotary angle of the plumbing arm sleeve and a rotary angle of the plumbing arm; and when the plumbing arm sleeve and the plumbing arm are rotated for one tooth in an opposite direction, an adjusting precision of adjusting the plumbing arm is realized; and the adjusting precision is higher than the adjusting precision of rotating the previous plumbing arm.

Description

Technical field [0001] The invention relates to a connecting device of a steering gear drop arm. Background technique [0002] At present, the connection mode between the steering gear and the drop arm of the existing vehicle is that the inner spline on the drop arm is connected with the outer spline of the output shaft of the steering gear, and it is compressed by a nut. Since the position of the output shaft of the steering gear is already Make sure that the position of the drop arm cannot be adjusted by turning the output turn of the steering gear, only the relative position between the drop arm and the output shaft can be adjusted, and the drop arm is generally rotated by one or more spline teeth. Due to the connection strength requirements, the number of spline teeth is not many, generally between 20-40, so turning the vertical arm of one tooth will rotate about 10°. The position of the drop arm has a great influence on the driving performance of the vehicle, and the p...
