A wheel rim structure and system for improving crash performance

Abstract

The invention discloses a wheel rim structure and system for improving collision performance, which comprises a coaxially arranged hub bearing, a brake disc and a rim, the hub bearing is fixedly connected to the brake disc, the rim and the The hub bearing is fixedly connected by explosive bolts, the brake disc is provided with a through hole through which the explosive bolt passes, and a spring is connected between the brake disc and the hub bearing. The invention enables the tires to come out automatically during the collision process of the vehicle, which reduces the deformation of the A-pillar, the intrusion of the cockpit, and the lateral displacement of the steering wheel. At the same time, there is a spring connection between the tire and the hub bearing to ensure that no damage is caused to surrounding vehicles and pedestrians after the car comes out.

Description

technical field [0001] The invention discloses a wheel edge structure and system, belongs to the technical field of wheels, and specifically discloses a wheel edge structure and system for improving collision performance. Background technique [0002] After the vehicle collides, the wheels are "squeezed" into the cockpit by the front barrier as a rigid body. The cockpit is deformed, the driver is impacted and squeezed, and the driver and passengers are injured. At the same time, the wheels cannot autonomously avoid the collision, and the vehicle may also drive the steering column to move or deform, resulting in lateral displacement of the steering wheel. The direct result is that in the event of a collision, the airbag ejected from the steering wheel of the vehicle cannot produce a positive impact on the head of the occupant on the seat. Contact will cause the occupant to lean forward too much, or the head will directly hit the hard structure inside the car, which will caus...

Cause the cockpit to deform, causing the driver to be impacted and squeezed, causing damage to the driver and passengers

At the same time, the wheels cannot autonomously avoid the collision, and the vehicle may also drive the steering column to move or deform, resulting in lateral displacement of the steering wheel. The direct result is that in the event of a collision, the airbag ejected from the steering wheel of the vehicle cannot produce a positive impact on the head of the occupant on the seat. Contact will cause the occupant to lean forward too much, or the head will directly hit the hard structure inside the car, which will cause greater damage to the occupants in the car
