Abstract

The invention relates to an anti-collision and anti-theft steering column for a vehicle, which comprises an upper steering shaft, an aluminum bracket, a nylon supporting sleeve, a precise positioning ring, a steering wheel, a universal joint fork, a steering gear fork and a spider, wherein the upper steering shaft is mounted in the aluminum bracket by two bearings, the steering gear fork is connected with a lower transmission shaft, the steering wheel is fixed on the upper end of the upper steering shaft by a spline and a nut, the lower end of the upper steering shaft is connected with the universal joint fork by a spline and a bolt, the universal joint fork is connected with the steering gear fork by a spider assembly, and the steering gear fork is connected with a lower steering shaft assembly by a spline to drive a steering gear to rotate. The invention has the advantages of simple structure and convenient operation.

Description

A kind of automobile-used anticollision anti-theft steering column

Technical field:

The present invention relates to a kind of automobile steering pipe post, particularly relate to a kind of vehicle anticollision steering column.Be widely used in various trucies, the anticollision dress steering column of passenger vehicle.

Technical background:

At present domestic at commercial vehicle/comm..vehicle, particularly truck on the passenger vehicle, also not yet has a kind of anticollision steering column of protecting driver safety so far, and this structure is a kind of brand-new steering column.

Summary of the invention:

The invention solves domestic on commercial vehicle/comm..vehicle the unsolved anticollision steering column of protecting driver safety so far, it is achieved in that a kind of automobile-used anticollision anti-theft steering column, it comprises steering shaft, aluminum frame, the nylon supporting sleeve, bearing, lock tube, the precise placement ring, Compress Spring, back-up ring, bearing circle, joint yoke, deflector distributary center cross forms, and it is characterized in that: upper steering shaft is installed in the aluminum frame by two steering shafts, and wherein a bearing is fixed on the steering shaft with the nylon supporting sleeve, the another bearing supports with Compress Spring, axial restraint; Described deflector fork connects lower drive shaft, aluminum frame is fixed on the vehicle body by the blanked part support, bearing circle has spline and nut to be fixed on the upper end of steering handwheel, bearing seat is installed in the endoporus of aluminum frame, the axial location of upper steering shaft is next spacing by the nylon supporting sleeve with pawl of fluting, lock tube is installed in the middle part of upper steering shaft by the precise placement ring, and the another bearing is to come spacing by the step on the upper steering shaft and Compress Spring; Upper steering shaft lower end is connected with joint yoke by spline and bolt, and described joint yoke is connected with the deflector fork by cross assemble, and the deflector fork links to each other with lower drive shaft by spline again, drives steering wheel and rotates.

The present invention is simple in structure, and is easy to use.

Description of drawings, Fig. 1 are structural representations of the present invention;

Deflector fork 4, center cross 5, joint yoke 6, back-up ring 10, packing ring 11, Compress Spring 12, bearing 14, lock tube 16, precise placement ring 17, back-up ring 18, aluminum frame 19, bearing 21, nylon supporting sleeve 23, bearing circle 24, nut 26, upper steering shaft 27,

The specific embodiment: the present invention is further described below in conjunction with accompanying drawing

A kind of automobile-used anticollision steering tube of the present invention, it is by bearing circle 24, upper steering shaft 27, nut 26, nylon supporting sleeve 23, bearing 21, lock tube 16, precise placement ring 17, bearing 14, Compress Spring 12, back-up ring 12, packing ring 11, joint yoke 2. cross assembles 5, deflector fork 4, aluminum frame 19 forms, and it is characterized in that: upper steering shaft is installed in the aluminum frame by two bearings, wherein a bearing is fixed on the steering shaft with the nylon supporting sleeve, and the another bearing supports with Compress Spring, and is axially fixed; Described deflector fork connects lower drive shaft, aluminum frame is fixed on the vehicle body by the blanked part support, bearing circle has spline and nut to be fixed on the upper end of steering handwheel, bearing seat is installed in the endoporus of aluminum frame, the axial location of upper steering shaft is next spacing by the nylon supporting sleeve with pawl of fluting, lock tube is installed in the middle part of upper steering shaft by the precise placement ring, and the another bearing is to come spacing by the step on the upper steering shaft and Compress Spring; Upper steering shaft lower end is connected with joint yoke by spline and bolt, and described joint yoke is connected with the deflector fork by cross assemble, and the deflector fork links to each other with lower drive shaft by spline again, drives steering wheel and rotates.During implementation, when car body is collided, the driver has a force of inertia forward, he removes at first first to oppress bearing circle, when bearing circle is subject to a downward power, it passes to upper steering shaft 27 with power, if upper steering shaft 27 will move down, at first the nylon supporting sleeve 23 of restriction bearing to be smashed, thus axle and bearing generation slippage, upper steering shaft 27 again with the tension force effect of Compress Spring 12 under, steering shaft is moved down rapidly, move down thereby drive bearing circle, increased the distance between driver and the bearing circle, being that the driver is unlikely is inflicted heavy losses on.Thereby protection driver's safety, lock tube and precise placement ring have been anti-theft functions, after car locks; dead bolt is stuck in the lock tube, and bearing circle can't rotate, the auto theft of robber's phase; will cut off by dead bolt, can drive, and this bassinet structure steering column; lock tube 16 is to be connected by precise placement ring 17 with upper steering shaft 27; the power of transmitting torque is through accurate Calculation, and unconventional welding, it is under powerful External Force Acting; lock tube and upper steering shaft just can skid, therefore can't twist off dead bolt.Therefore, robber's auto theft is at very large resistance rotation bearing circle always, is difficult to control direction, thereby plays anti-theft function.
