The beneficial effect of the utility model is: online 100% inspection of the routed power of internal turn axial compression; The size of absorbing impact impact energy can regulate and detect when the product Assembling Production; Can accurately set the size of crumple power and energy-absorbing, when collision happens, the accekeration during energy absorption device generation crumple is just more definite like this; Can alleviate the suffered injury of chaufeur better, have the crash protection function;
Anti-drop function: after the collision, prevent to pound behind the chaufeur knee after steering column from coming off and damage
Angular adjustment return function: after carrying out angular adjustment, use regulating spring, can utilize spring force to make steering column self-return (initial condition);
Regulating mechanism self-locking (locking functions): use self lock nut, the end face needle roller thrust bearing can prevent that locking mechanism locking back is loosening;
Anti-theft feature: 6 antitheft locked grooves are arranged, can rotate very at bearing circle and lock behind the low-angle.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the utility model mounting bracket parts cutaway views;
Fig. 3 is the utility model regulating mechanism parts cutaway views;
Fig. 4 is the birds-eye view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
As shown in Figure 1, said steering shaft section is made up of castellated shaft 25, splined sleeve 1, spring clip 30.The steering torque of the main direction of transfer dish of these parts; Wherein be pressed into spring clip 30 between splined sleeve 1 and the castellated shaft 25; Spring clip 30 is the main axial crumple energy-absorbing functions that rise, and the chaufeur health is passed to the axial component of the pressure of bearing circle when auto against, through the crumple of the interior external diameter friction force generation between spring clip 30 and splined sleeve 1 and the castellated shaft 25; Thereby the absorption axial force alleviates the chaufeur injury.Wherein vital part is a spring clip 30, and this is a kind of custom-designed tolerance ring structure, the destructive force when its friction force through surfaces externally and internally and splined sleeve 1 and castellated shaft 25 comes the accuracy control collision, and distortion absorbs energy.Carry out on-line monitoring to being pressed into power during these parts press-fiting assembling, system can report to the police (thereby guarantee energy-absorbing accuracy) when being pressed into the power nonconformity.
As shown in Figure 1, said tube column parts are welded by tube column 19 and mounting bracket parts, combined switch support 21, and radical function is to support steering shaft section, and steering shaft section can freely be rotated, thereby transmit steering torque.Said mounting bracket parts (seeing Fig. 1,2) are made up of mounting bracket 3, lower bracket 23, buffering stand 22, installation conduit 16, jointed shaft left side packing ring 17, the right packing ring 18 of jointed shaft; Wherein, The mounting bracket parts are that other part press-fits, is welded into the mounting bracket parts with mounting bracket 3 through mounting bracket 3 and the left end cylindrical weld together of keeping a grip on body 19.Combined switch support 21 with keep a grip on body 19 right side weld togethers, combined switch support 21 have 6 the antitheft locked grooves, can rotate very at bearing circle and lock behind the low-angle.Keeping a grip on body component and steering shaft section links together through antifriction-bearing box 6 and needle bearing 2 and O type circle 5, shaft block ring 7.Wherein needle bearing 2 is at the left end hole place that keeps a grip on body 19, through being pressed into, and with lining cement and keep a grip on the inside face of body 19 and the outside face of splined sleeve 2 bonds together.Antifriction-bearing box 6 is to press to locate in the right hole of keeping a grip on body 19 with the axle bumper part, mainly is to be fixed together with castellated shaft 25 keeping a grip on body 19.Keep a grip on body component and steering shaft section like this and just connect into an integral body through the needle bearing 2 of left end and the antifriction-bearing box 6 of right-hand member; Keeping a grip on body component is installed on the automobile through the mounting bracket parts; Castellated shaft 25 is connected with bearing circle, and can rotate transfer torque through bearing.
Like Fig. 1,3, shown in 4.Said regulating mechanism parts are that regulating support 4 is to link together with fixed support 24 through pivot pin 8, wire harness bracket 20, handle body 31, taper knob 32, regulating spring 29, pivot pin cover 10, adjusting cam 11, flat gasket 13, needle roller thrust bearing 14, self lock nut 15 through fixed support 24 and the middle part cylindrical weld together of keeping a grip on body 19.In assembling during handle body 31, through 31 lockings of tension-compression sensor on-line monitoring handle with adjustment force when unclamping, can easy adjustment when regulating steering wheel position to guarantee chaufeur.The radical function of regulating spring 29 is after carrying out angular adjustment, uses regulating spring, can utilize spring force to make steering column self-return (initial condition), uses self lock nut 15, and the end face needle roller thrust bearing can prevent that locking mechanism locking back is loosening.The regulating mechanism radical function be regulate the vehicle steering angle with highly to adapt to the chaufeur of different heights.
