From during be conditioned support and clamp and stretch, and effectively absorb vehicle collision energy.
As preferred：The part being located in described adjusting bracket in described steel band is provided with bending, this bending undulate.Adopt
Use above structure, effectively increase the damping action to steel band for the adjusting bracket, steel band can be stretched in separation process by adjusting bracket,
Thus inhaling vehicle in a large number to receive collision energy.
As preferred：Described adjusting bracket and steel band mounting blocks are connected using injection.Using above structure, make adjusting bracket
Steel band mounting blocks can be departed from during the crumple of upper pillar and lower pillar, effectively absorb vehicle collision energy simultaneously.
As preferred：Described cannelure is coaxially disposed with described main shaft.Using above structure it is ensured that outside to main shaft and main shaft
The locking active force equilibrium of pipe.
As preferred：Described cannelure has two circles, and each injection part has two protuberances, in described main shaft outer tube
It is provided with four corresponding spacing holes, this spacing hole one group of axis both sides being symmetricly set on main shaft outer tube two-by-two.Adopt with
Upper structure, had both been easy to injection assembling, had realized to main shaft and the more structurally sound locking of main shaft outer tube again.
As preferred：Described main shaft and main shaft outer tube are coordinated by spline slide.Using above structure, structure is practical, can
Lean on, it is easy to accomplish, with low cost.
Compared with prior art, the beneficial effects of the utility model are：
The injection collapse type electric boosting steering system steering gear being provided using this utility model, structure novel it is easy to real
Now, the injection part of countershaft assembly and the steel band of dependency structure and steering column and dependency structure, substantially increase steering gear
Crumple energy-absorbing ability, thus improve the safety of automobile, protection driver avoid in vehicle collisions or subtract
Few injury, has high practicality.
