Abstract

The utility model relates to a safety steering device for automobiles, comprising a steering wheel, a steering shaft, a steering gear, etc. A spring casing tube is arranged between the steering shaft and the steering gear, and a pressure spring is arranged in the spring casing tube. One end of the spring casing tube is fixed to the steering wheel through the steering shaft, and the other end of the spring casing tube is fixed to a spline housing. A spline shaft is sheathed in the spline housing. One end of the spline shaft is fixed to the steering gear, and the other end of the spline shaft is connected with the pressure spring of the spring casing tube.

Description

A kind of secure side is to machine

The utility model relates to a kind of secure side to machine.

Chaufeur is driving a car when travelling, and changes the travel direction of automobile by the steering wheel rotation controlling party to machine, when contingency such as emergency brake and collision takes place, wound driver's phenomenon of bearing circle usually occurs.

The purpose of this utility model is to provide a kind of automotive safety direction machine, can effectively avoid wound driver's phenomenon of bearing circle to take place when emergency brake and contingency take place.

The purpose of this utility model is achieved in that the utility model comprises bearing circle, steering shaft and deflector etc., a pogo barrel is housed between steering shaft and deflector, stage clip is housed in the pogo barrel, one end of pogo barrel is captiveed joint with bearing circle by steering shaft, the other end of pogo barrel fixedly is equipped with a spline housing, hub splines is contained in the spline housing, and an end of castellated shaft is captiveed joint with deflector, and the other end of castellated shaft connects the stage clip in the pogo barrel.

Use the utility model, the operation of motor turning is finished in direction of passage dish, steering shaft, pogo barrel, spline housing, castellated shaft to deflector, contingencies such as emergency brake and collision are appearring, automobile stops suddenly, the driver answers back to when bearing circle owing to effect of inertia, press down stage clip, play buffer action, the driver's that can effectively avoid wounding phenomenon takes place.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is the utility model running condition scheme drawing.

Accompanying drawing 3 presses down the process scheme drawing for the utility model.

Accompanying drawing 4 is the utility model pressed status scheme drawing.

As shown in Figure 1, the utility model steering shaft 2 is sleeved in the sleeve pipe 3, between steering shaft 2 and the sleeve pipe 3 rubber bush 14 is housed, sleeve pipe 3 is sleeved on the fixed sleeving 4 on the fixed mount 5, and the clench nail 6 that is installed between sleeve pipe 3 and the fixed sleeving 4 can move along the slide opening on the sleeve pipe 3 13.

Shown in accompanying drawing 1,2, when automobile normal running, steering box keeps original function, when turning to, but the pogo barrel 7 that direction of passage dish 1, steering shaft 2 and steering shaft 2 are captiveed joint, power is delivered on the spline housing 10, spline housing 10 passes to deflector 12 by castellated shaft 11 with power again and realizes turning to of wheels.

When automobile meets accident accident, example emergency brake or collision, automobile stops suddenly, the driver is because the effect of force of inertia can be pressed to bearing circle 1 suddenly, this moment, bearing circle 1 meeting press down pogo barrel 7 by steering shaft 2, move axially between spline housing 10 and the castellated shaft 11, be that castellated shaft 11 presses down stage clip 8, stage clip 8 compressions, as accompanying drawing 3, shown in 4, this moment is because steering shaft 2 is by sleeve pipe 3, fixed sleeving 4, fixed mount 5 is fixed on the instrument carrier panel, and clench nail moves along slide opening 13 for 6 this moments, so the upper space of operator's compartment is constant, just bearing circle 1 vertically moves, maximum can move down 100 millimeters, can prevent effectively that steering shaft top from wearing driver's chest, plays the safety precaution effect.

The utility model is simple and reliable for structure, does not influence former steering system in-use performance again, provides useful guarantee to the life security of chaufeur.
