Description

Stress structure for mounting suspension and tunnel-shaped inner frame and outer frame at top of vehicle

The technical field is as follows: the invention relates to a vehicle integral structure, in particular to a stress structure for mounting a suspension and a tunnel-shaped inner frame and a tunnel-shaped outer frame on the top of a vehicle.

Background art: the automobile is a special moving machine, because the transverse gravity center of the vehicle is easy to swing left and right when the vehicle turns or runs straight to hit the direction suddenly due to the complexity of the road, the control technology of the driver, the structural difference of the vehicle and other factors, the light passenger can feel uncomfortable to the passenger, the stability and the safety of the automobile control can be affected seriously to cause traffic accidents, and the factors which cause the transverse gravity center to swing left and right in the running process of the vehicle mainly comprise the control technology of the driver, road condition factors and automobile suspension, tire faults and suspension support structures: the driver control technology mainly comprises the steps that goods or personnel are loaded in an unbalanced manner, the loaded goods are not firmly fixed and roll, or the horizontal fluctuation of liquid causes the left and right swinging of a vehicle body when a driver balances the transverse gravity center by adopting a steering wheel, the transverse gravity center deviates to one side due to insufficient tire air pressure of one side, the vehicle does not decelerate when turning, or the vehicle body shakes violently due to the centrifugal force generated in the sharp turning direction when the vehicle is at a high speed, and the higher the swing of the vehicle body is, the larger the swing is; road conditions mainly comprise that the transverse gravity center swings left and right due to the fact that the road surface is uneven, and the transverse gravity center of a vehicle is out of control due to the fact that wheels slip due to ice, snow, mud and slippery roads and curved roads; the automobile suspension and tire faults mainly include faults or damages of elastic elements of an automobile suspension system, faults or damages of a hydraulic system, damages of tires or insufficient air pressure and the like; the influence of the suspension support structure on the lateral gravity center of the vehicle body mainly comprises the following aspects from the aspect of elastic support mechanical characteristics:

firstly, the suspension is a general term of all elastic elements, the controllability and the comfort can not be considered simultaneously in the prior art, for example, when the rigidity strength of a suspension system is low, the user can sit comfortably, but the elasticity is good, so that the stability of a supporting vehicle body is poor, the swing amplitude of the upper part of the vehicle body is increased, and the controllability is poor, therefore, the vehicle body of a plurality of cars is often reduced to be very low in order to meet the requirements of the stability and the comfort of the vehicle, the gravity center of the car is reduced and the suspension rigidity is soft, the gravity center of the vehicle is reduced and the elasticity is soft, so that the stability, the average vehicle speed, the controllability and the comfort of the vehicle are improved well, but the height space in the rear car is reduced, so that the body of the person sitting in half and lying in a half is uncomfortable after sitting for a long time, and the person is difficult to get on or off the car due to the low vehicle body, and particularly the old people are more prominent, does not conform to the ergonomic design criteria of various human postures, such as space size and the like; when the suspension is positioned at the bottom of the vehicle body, the geometric shape of the vehicle body and the volume-to-weight densities of the upper part and the lower part of the vehicle body have correlation influence on the stability of the gravity center of the whole vehicle, through data analysis of various side-turning vehicle traffic accidents, the side-turning proportion in a low vehicle type is lower, the side-turning proportion in a vehicle type with a higher vehicle body is higher, which shows that the stability of the vehicle running in various environments is closely related to the geometric shape of the whole vehicle, the stability of the gravity center of the vehicle body is better when the height of the vehicle body is lower, and the stability of the gravity center of the vehicle body is worse when the vehicle is higher and the width is narrower, so that the principle of one inch swing of a bottom building and 1 meter swing of a 30-floor can be consistent when the building encounters an earthquake; secondly, the composition of the density of substances at each part of the vehicle is closely related to the stability of the center of gravity, and the structure of the joint of the body and the chassis of the car is compact and the gap at the bottom is less under normal conditions; the middle part of the combination of the body and the chassis of the large and medium-sized vehicle has a loose structure, the gap of the middle part is more, when the vehicle is unloaded, the weight-volume ratio of the body and the chassis is almost equal, when the vehicle is fully loaded, the weight of the upper part of the body is obviously heavier than that of the chassis, the upper part is heavier than the lower part, and the lower part is lighter.

The suspension is a connecting device for all force transfer between a wheel and an axle and a vehicle body, when an elastic element supports an object, the supported object is easy to swing due to the elastic action, the higher the gravity center is, the larger the swing amplitude is, and when the supported object is superposed by various complex forces in the motion process of the vehicle, the swing and the swing amplitude are aggravated, wherein the connection mode or the stress point of the suspension and the vehicle frame or the bearing type vehicle body has the following effects on the dynamic mechanical property of the vehicle: 1. The swinging of the supported vehicle body makes the transverse gravity center of the vehicle body unstable, so that the grip force and the braking force of the wheels on the weightlessness side are deteriorated, and the simultaneous out-of-control of the braking and the direction can be caused; 2. the swinging of the supported vehicle body makes the vehicle body uncomfortable to sit when the transverse gravity center of the vehicle body is unstable, and passengers feel uncomfortable or feel carsickness and other adverse reactions because the vehicle body swings left and right at times during driving; 3. the swing of the supported vehicle body ensures that the transverse gravity center of the vehicle body is unstable, and the direction and the brake are out of control easily when the vehicle body encounters wet and slippery road surfaces or transverse wind power; 4. the swinging of the supported vehicle body ensures that the transverse gravity center of the vehicle body is unstable and influences the average running speed, and when the vehicle turns or encounters a wet slippery road surface, the transverse gravity center of the vehicle body is unstable and easily generates centrifugal force to incline to one side so as to be forced to decelerate and reduce the average speed; 5. the swinging of the supported vehicle body ensures that the transverse gravity center of the vehicle body is unstable and the vehicle frame or a suspension device is easily damaged when the vehicle body encounters impact force; certain adverse effects are produced on the safety and service life of the vehicle.

In the prior art, wheels on two sides are generally as wide as a vehicle body, a road surface is a supporting base for the weight of the whole vehicle, and the levelness of the road surface has a correlation influence on the gravity center of the whole vehicle and the levelness of the top of the vehicle body; the wheels are the supporting bases of the suspension, the suspension is the supporting base of the vehicle body, and the wheels support the vehicle body on different vertical lines; the connection mode makes the space above the left and right wheels easily generate elastic deformation due to large gap when the vehicle is heavily loaded, and is one of the inducements of vehicle swing and rollover, people who do not know the vehicle structure can see that the wheel supports completely cover the vehicle body, but the vehicle type supported by the suspension is retracted by half of the total width, so that the supporting surface of the suspension to the vehicle body is narrowed, most vehicles do not actually obtain strong support on the whole section of the vehicle body from the outside of the vehicle frame to the above wheels, and the structure presses the wheels to generate elastic deformation to make the side wheels and the suspension incline to the side when the suspension is heavily loaded due to the fact that the space outside the section does not have substantial support to press the wheels to incline to make the side wheels and the suspension generate elastic deformation to aggravate the vehicle body, the wheel and the elastic element on the other side enable the support to be rapidly increased under the action of the air pressure of the tire and the elastic force of the elastic element, so that the gravity center of the upper part of the automobile body is inclined to the lower side of the support, the gravity centers on the two sides are not balanced to generate the lateral gravity center deviation of the automobile, the gravity center deviation is continuously superposed with the acceleration of the centrifugal force along with the deepening of the turn, so that the average support of the front wheel and the rear wheel on the two sides is gradually changed into the front wheel and the rear wheel support on one side, at the moment, the huge body of the automobile is easy to shake and swing under the support of the wheels at one side, so that the edge of the wheel is only contacted with the ground under the condition that the gravity center passes through the central line of the wheel at one side again seriously, therefore, when the upper part of the vehicle body swings violently left and right, the braking and the instantaneous failure of the direction are possibly caused, the transient chain reaction sometimes makes the operator have no time or control at all, and causes traffic accidents such as vehicle runaway or vehicle rollover directly.

In the prior art, the vertical stress angle between the suspension and the wheel and the stress angle of the transverse support of the axle in part of the independent suspension structure can cause the tire to be stressed by load when the suspension is compressed, so that the transverse support of the axle is lengthened to extrude the tire outwards, and the transverse support is shortened to cause the tire to move inwards when the suspension is contracted, so that when the tire fluctuates up and down due to heavy load, no load, uneven road surface or other reasons in the driving process of the vehicle, the tire and the road surface can repeatedly move inwards and outwards and transversely and the linear motion of the wheel is crossed with each other to form the curvilinear motion of the tire and the road surface when the vehicle drives, and the abrasion speed of the tire is increased.

When a traffic accident occurs, the vehicle is often called as a road killer, the stability and the safety of vehicle driving are key technologies in the fields of vehicle design, manufacture and application, and relate to the life and property safety and economic benefits of people, China is a large population country in the world, along with the continuous improvement of economic and living levels, the ownership of motor vehicles and non-motor vehicles is continuously increased, but the traffic safety problem is increasingly highlighted, tens of thousands of lives are swallowed by the traffic accident every year, mental injuries and economic losses which are difficult to be worn out are brought to the nation and people, and nowadays of the continuous development of science and technology, the weak links of automobile structures and the disaster causing laws of vehicles are scientifically known, and disasters and risks caused by automobile traffic accidents are practically and effectively relieved and prevented. In spite of the frequent occurrence of traffic accidents, most of the traffic accidents are related to the structural defect that the stressed supporting structure of the suspension is not scientific enough and the pressure-bearing and impact-resisting structure of the car body does not meet the safety requirement, namely the so-called 'meat wrapped by paper'.
