Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in figures 1-8, a kind of car steering wheel anti-collision energy absorption device, it comprises steering handwheel 1, one end and the steering handwheel 1 of Steering gear 2 are fixedly linked, the other end and steering column 4 form key by spline 18 and are connected, axially stop block 3 and Steering gear 2 form to slide and scalablely coordinate and be fixedly connected with one end of steering column 4, the other end of steering column 4 is connected with input shaft universal-joint 5, one end of transmission shaft 6 is connected with input shaft universal-joint 5, the other end is connected with output shaft universal-joint 7, and described Steering gear 2 is processed with tooth bar 21.The moment of torsion of steering handwheel 1 can be transferred on output shaft universal-joint 7 by Steering gear 2, steering column 4, input shaft universal-joint 5 and transmission shaft 6 by above-mentioned connection.
As Fig. 2-3, further, described axially stop block 3 comprises box cover 8 and casing lower cover 9, gear wheel shaft 17 is installed between box cover 8 and casing lower cover 9, gear wheel shaft 17 is processed with gear 15 and ratchet 14, gear wheel shaft 17 two ends are arranged on box cover 8 respectively by bearing 13 and casing lower cover 9 matches on the bearing seat of formation, and roller bearing end cap 11 is fixedly linked with box cover 8 and casing lower cover 9 by bolt of cover 12 simultaneously.Can limit the axial location of Steering gear 2 by arranging axially stop block 3, thus facilitate the adjustment of steering handwheel 1 height, can ensure that Steering gear 2 axially moves down along it under pressure simultaneously, thus reduce the height of steering handwheel 1.
Further, be provided with lock pin 10 in the knock hole of described box cover 8, lock pin 10 outer cover is equipped with spring 19, and the end of lock pin 10 has been threaded connection handle 20, and lock pin 10 matches with ratchet 14, realizes the position and lock of gear wheel shaft 17.Can be locked ratchet 14 by lock pin 10, and then the position of Steering gear 2 is locked.
Further, one end that described Steering gear 2 matches with steering column 4 is processed with centre hole, and centre hole internal sleeve is equipped with recoil spring 16, and Steering gear 2 and steering column 4 form bearing fit.Can play buffer action to Steering gear 2 by recoil spring 16, under generation effect of impact, Steering gear 2 moves downward thus recoil spring 16 will be played buffering object by compression, prevents chaufeur from directly striking on steering handwheel 1.
Further, described gear 15 forms gear transmission with tooth bar 21 and coordinates.When Steering gear 2 moves along its axis direction, rotated by driven gear 15, and then driven gear axle 17 rotates, simultaneously after ratchet 14 is locked, gear 15 will coordinate with tooth bar 21, and then positions Steering gear 2.
Further, described transmission shaft 6 simultaneously and form double universal joint pin cardan joint driving device between input shaft universal-joint 5 and output shaft universal-joint 7.
Employing utility model works principle is:
This patent is a kind of car steering wheel anti-collision energy absorption device, and Steering gear 2 is connected by spline 18 with steering column 4, transmits the moment that steering handwheel applies.The gear 15 of axially stop block 3 inside engages with the tooth bar 21 on Steering gear 2, and gear 15 is coaxial with ratchet 14, and rotation direction is identical.Lock pin 10 coordinates with ratchet 14, can make ratchet 14 unidirectional rotation by moving radially along ratchet 14 of lock pin 10, thus driven gear 15 unidirectional rotation.Gear 15 unidirectional rotation just makes Steering gear 2 to move downward.Recoil spring 16 is had between Steering gear 2 and steering column 4, the impact kinetic energy that steering handwheel 1 causes can be clashed into by chaufeur in cushioning automobile crash process, and axially stop block 3 stops Steering gear 2 upward movement, thus chaufeur can be stoped to collide the secondary injury that in the process of steering handwheel 1, Steering gear 2 resilience causes chaufeur.Steering handwheel 1 can be allowed fast to return to initial position by stirring lock pin 10, thus the height of steering handwheel 1 can be regulated.
Above-described embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
