Abstract

The utility model provides a holding wheel mechanism and a safety car with the same. The holding wheel mechanism comprises boosting seats, returning seats and lower pressing seats, wherein the boosting seats and the returning seats are arranged in front and back of wheels; the lower pressing seats are positioned above the wheels; the boosting seats are connected with the returning seats through an upper transmission component and a lower transmission component; a spring is arranged on the lower transmission component; and the lower pressing seats are hinged with the boosting seats and the returning seats through hinging components. The holding wheel mechanism is arranged on all wheels of the car. Through the adoption of the holding wheel mechanism and the safety car with the same, the impacting force produced by the impacting can be effectively reduced by being buffered and absorbed through a group of springs, and then the level force and the inclination force which are lengthways transmitted to the front or/and back are converted into forces which are oppositely pressed and vertically downwards acted and then acted on the wheels, so that the high capacity on bearing and pressure resisting of charging tyres of wheels is fully utilized, the impacting force is transmitted to the ground, and the vehicle body structure can be prevented from being crushed, deformed and damaged under the impacting force, and as a result, the driver and the passenger in the car can be effectively protected, and the three safety effects on impacting resisting, car protecting and people protecting can be achieved. The holding wheel mechanism and the safety car are applicable to various current cars, particularly can solve the problem that various car-over-engine buses and trucks are poor in safety in impacting due to the lacking of an energy absorbing deforming area.

Description

Wheel holding mechanism and with the accident-free vehicle of this wheel holding mechanism

Technical field

The utility model relates to a kind of wheel holding mechanism, and the safety vehicle with wheel holding mechanism is provided, and belongs to automobile component and Automobile Design and Manufacturing technical field.

Background technology

Automotive safety is divided into active safety and passive security, and passive security claims again collision safety.Active safety is handling closely related with driving, and passive security is then closely related with the structure design of automobile self, and passive security plays a major role in automotive safety simultaneously.The safeguard construction of existing automobile can be divided in body structure and the car driver and crew and protect structure such as safety strap, safety air bag, safe steering swivel system, safety seat etc.; body structure can cushion and energy-absorbing; play a major role in lowering impact power, driver and crew protect structure to play the secondary role of protection in the car.According to the America and Europe statistics of various car accidents is shown, front hitting at most, rear-end collision takes second place, and side is hit and is taken second place.So impinge upon before and after longitudinally the most common in the accident (＞60%-70%).With regard to the most general existing three box car structure, have following characteristics: middle vehicle body is that the crew module is harder, and bodyshell rigidity is larger, and the front and back vehicle body is that machinery space, boot compartment are softer, and rigidity is less, and certain toughness is arranged.When being subject to clashing into, by the compressive deformation of front and back vehicle body, absorb as much as possible the impact energy of bump, to lower the impact damage to the crew module.But this to only depend on the conquassation distortion of the forward and backward vehicle body of automobile such as machinery space, boot compartment be that the form that car is ruined is come buffering energy-absorbing, the energy of its snubber is extremely limited, as: with the celebrated European Euro-NCAP of the strictest testing standard in the whole world, the full test speed per hour that obtains the highest 5 asterisk standards in its new car head-on crash (40%ODB) test is no more than 64km/h(America and Japan therewith roughly the same), so its safe effect only limits to the low-medium speed collision.Along with the fast development of express highway, the greatly increase of automobile driving speed, the auto against speed per hour also significantly improves, so the limitation of prior art highlights day by day and can't essence solve.Etesian a large amount of " car crash " automobile collision accident examples in the current whole world have proved absolutely this point.Therefore, for the defective of existing automotive body structure, must research and develop new safe vehicle body structure and satisfy modern traffic safety.
