Abstract
The utility model relates to a ball spline type steering transmission device for a vehicle, which is connected with a universal joint fork through a precise ball spline kinematic pair, both ends of the ball spline type steering transmission device are connected with the universal joint fork through a universal cross joint assembly, and the precise ball spline kinematic pair is composed of a double circle arc rolling path which is on a spline sleeve pipe, a double circle arc spline groove which is on a steering drive shaft, balls and a ball holder. One end of the ball spline type steering transmission device is connected with an upper steering column assembly, and the other end of the ball spline type steering transmission device is connected with a direction machine or an angle steering device. A ball spline type structure is adopted, the sliding resistance between the spline sleeve pipe and the steering drive shaft is decreased, and the high frequency resonance, the noise and the temperature rising are eliminated effectively.
Description
Technical field: the utility model relates to a kind of automobile steering transmission linkage, particularly relates to a kind of motor turning driving device bottom steering inner articulated shaft ball spline formula steering transmission linkage.
Technical background: at present, the steering transmission linkage of the various models that domestic automobile producer is disposed, its underpart steerage gear axle assembly partly is spline contact structure with the telescopic slide structure, that is to say that splined sleeve and steering inner articulated shaft are directly by spline fitted and slip, be pure slip when therefore working between splined sleeve and the steering inner articulated shaft, flexible resistance is big, and the spline wearing and tearing are big, cause to turn to and reverse gap increase.In order to overcome above defective, the purpose of this utility model will provide a kind of ball spline formula steering transmission linkage exactly, the utility model adopts ball spline formula structure, sliding force between splined sleeve and steering inner articulated shaft during work, rolling power is only arranged, and rolling power is very little, therefore greatly reduces to spend spline wearing and tearing between strong sleeve pipe and the steering inner articulated shaft, effectively abate the noise when simultaneously, guaranteeing work, temperature rise.This device is used to connect between column assy and the direction machine, also is used to connect between column assy and the angle deflector, and between angle deflector and the direction machine, works to transmit steering torque and adapt to flexible.
Summary of the invention: the purpose of this utility model is to realize like this, ball spline formula steering transmission linkage is made up of joint yoke assembly, splined sleeve, steerage gear spindle unit, it is characterized in that: all have the duplex circular ares profile race groove in the inwall both sides of described splined sleeve and the both sides on steering inner articulated shaft top, and ball is installed, and the two ends of ball are fixed by ball retainer; Spacing at steering inner articulated shaft spline part two ends with back-up ring; End at described splined sleeve is connected with the joint yoke assembly, and the other end links to each other with steering inner articulated shaft with skeleton with seal ring.Form accurate ball spline kinematic pair by ball between duplex circular ares profile race in the splined sleeve and the two circular arc splines on the steering inner articulated shaft, two ends are connected by joint yoke.In the forced stroke of regulation, ball rolls splined sleeve and steering inner articulated shaft is subjected to displacement, the needs of static state and dynamic distance between assurance automobile steering machine (vehicle frame) and the bearing circle (vehicle body), joint yoke assembly by these product two ends, make this device between vehicle frame and vehicle body, form a kind of flexibly jointed chain, can effectively eliminate X, the Y from vehicle frame, the three-dimensional vibrations of Z.Make automobile when running at high speed, effectively eliminate high frequency shake altogether, noise and temperature rise.
Description of drawings: Fig. 1 is a structural representation of the present utility model
1, joint yoke assembly 2, splined sleeve 3, back-up ring 4, ball retainer 5, ball 6, seal ring 7, skeleton 8, steering inner articulated shaft 9, joint yoke assembly
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:
In diagram, the utility model ball spline formula steering transmission linkage is made up of joint yoke assembly 1, splined sleeve 2, steering inner articulated shaft 8 parts, it is characterized in that: all have the duplex circular ares profile race groove in the inwall both sides of described splined sleeve 2 and the both sides on steering inner articulated shaft 8 tops, and ball 5 is installed, and the two ends of ball 5 are fixing by ball retainer 4; Spacing at steering inner articulated shaft 8 spline part two ends with back-up ring 3; End at described splined sleeve 2 is connected with joint yoke assembly 1, and the other end links to each other with steering inner articulated shaft 8 with skeleton 7 with seal ring 6.Splined sleeve internal tooth flute profile is a duplex circular ares profile race, and steering inner articulated shaft external tooth flute profile also is a duplex circular ares profile race, and inside and outside duplex circular ares profile race cooperates contact by ball, and ball is fixed by retainer, and is spacing by back-up ring at steering inner articulated shaft spline part two ends, prevents that ball from coming off.Splined sleeve and steering inner articulated shaft be by the ball transfer torque, adapts to the function of having only the fricton-tight power of rolling power when flexible and flexible to reach.The diagram ball is the normal operation travel position on the steering inner articulated shaft spline segment, when spending strong sleeve pipe and steering inner articulated shaft that a certain amount of relative displacement takes place, only there is rolling in ball, therefore has only rolling power, reduce the wearing and tearing of spending between strong sleeve pipe and the steering inner articulated shaft greatly, effectively eliminate shake, noise and temperature rise altogether.
