Abstract

The invention relates to a variable-crumple-force crumpling mechanism for a steering column. An outer sleeve of the steering column has an inner tube and an outer tube which are arranged coaxially andare non-rotatable relative to each other, and the outer tube at least partially encircles the inner tube on the outside. The crumpling mechanism comprises a solenoid valve with an extendable bolt, acrumple guide box fixed at the end part of the outer tube, a crumple stop block being fixed on the inner tube and being embedded into a crumple opening formed in the end part of the outer tube in an interference fit manner, a plurality of crumple pieces and spacers, wherein the plurality of crumple pieces and the spacers are sequentially and alternately arranged. The solenoid valve is fixed on thecrumple guide box; the plug pin is configured to be capable of being inserted into a plug pin hole; the crumple pieces and the spacers have the same shapes and are respectively provided with throughholes with the same shapes as the plug pin hole at the positions aligned with the plug pin hole in the crumple guide box, and the plug pin can be actuated by a magnetic force generated by the solenoidvalve and extends towards the through holes of the crumple pieces and the spacers.

Description

technical field [0001] The invention relates to a vehicle steering system used in the field of automobile industry, in particular to a collapsing mechanism with variable collapsing force for a steering column of a vehicle. Background technique [0002] A vehicle steering system is a combination of components used to change or maintain a vehicle's direction of travel or reverse. One of the important components is the steering column, which is arranged between the steering wheel and the body of the vehicle, and its main function is to transmit the steering force applied by the driver to the steering drive shaft and then to the steering column. to change the direction of travel of the vehicle. The steering column mainly includes an outer sleeve and a steering shaft arranged coaxially. Wherein, the outer sleeve is fastened on the vehicle body; the steering shaft passes through the outer sleeve and is rotatably supported on the inner wall of the outer sleeve, one end of the ste...
