Lorry has two along its length and is carrying lorry casing or tank body or crew module 1 on the left longeron 15 of vehicle frame, vehicle frame right vertical beam 16, two longerons at the chassis side rail of the parallel laying of same level face.The left longeron 15 of vehicle frame, vehicle frame right vertical beam 16 rear portions (segment distance) are laid three rear anti-crash entablatrances 11 that parallel, rear anti-crash center member 12, rear anti-crash cross sill 13, three rear anti-collision cross beams are in same vertical plane, and this vertical plane is vertical with the left longeron 15 of vehicle frame or vehicle frame right vertical beam 16.Take level ground as benchmark, rear anti-crash entablatrance 11 is higher than the left longeron 15 of vehicle frame or vehicle frame right vertical beam 16, and rear anti-crash center member 12 maintains an equal level with the left longeron 15 of vehicle frame or vehicle frame right vertical beam 16, and rear anti-crash cross sill 13 is lower than the left longeron 15 of vehicle frame or vehicle frame right vertical beam 16.The both sides that three rear anti-collision cross beams are rear anti-crash entablatrance 11, rear anti-crash center member 12, rear anti-crash cross sill 13 vertically connect left column 4, right column 14 by bolt respectively.The length of rear anti-crash entablatrance 11 is a bit larger tham lorry casing or tank body or crew module's 1 width.
Left outside crashproof cant beam 2, right outside crashproof cant beam 7 be upper angled backward, both front ends (or claiming the lower end) are captiveed joint by the rear portion of the left longeron 15 of overbolt and vehicle frame, vehicle frame right vertical beam 16 respectively, and both rear ends (or upper end) captives joint with the end at rear anti-crash entablatrance 11 two ends respectively.Crashproof cant beam outside about the vehicle tail left and right sides installs additional, purpose are in the situation that biasing is knocked into the back, and the left and right sides of the vehicle (front truck) that knocked into the back is protected.
Upper left energy-absorbing cant beam 3, upper right energy-absorbing cant beam 8 be upper angled backward, its inclination angle is greater than the inclination angle of left outside crashproof cant beam 2, right outside crashproof cant beam 7, both front ends (or claiming the lower end) are captiveed joint by the rear portion of the left longeron 15 of bolt and vehicle frame, vehicle frame right vertical beam 16 respectively, and both rear ends (or upper end) captives joint with rear anti-crash entablatrance 11 respectively.
The front end of left vertical energy-absorbing cant beam 5, right vertical energy-absorbing cant beam 9 is captiveed joint by the left longeron 15 of bolt and vehicle frame, vehicle frame right vertical beam 16 respectively, and both rear ends are connected with rear anti-crash center member 12 respectively.
Lower-left energy-absorbing cant beam 6, bottom right energy-absorbing cant beam 10 are downward-sloping, both front ends (or upper end) are captiveed joint by the left longeron 15 of bolt and vehicle frame, vehicle frame right vertical beam 16 respectively, captive joint with rear anti-crash cross sill 13 respectively in both rear ends (or claiming the lower end).
Can be according to the needs of technique, above-mentioned captive joint mode can partly or entirely adopt rivet or welding manner to connect.
In the design plan of the present utility model, the plane at lorry casing or tank body or crew module's 1 aft end face and rear anti-crash entablatrance 11, rear anti-crash center member 12, rear anti-crash cross sill 13 places has the safety collision space D.The value of safe spacing D is about 50cm, and this distance is optimized design according to factors such as vehicle tonnage, bearing goods character.The vehicle tonnage is higher, and the danger of bearing goods is larger, then suitably increases the value of safe spacing D.
When positive rear-end collision occurs when, the large plane that is formed by left column 4, right column 14 and rear anti-crash entablatrance 11, rear anti-crash center member 12, rear anti-crash cross sill 13, can effectively increase area of thrust surface, thereby greatly increase the area of thrust surface of vehicle (the rear car) that knock into the back, effectively bring into play the effect (intensity of general lorry front end operator's compartment is less) at its anterior crumple energy-absorbing position.Simultaneously, the common energy-absorbing function of upper left energy-absorbing cant beam 3, upper right energy-absorbing cant beam 8, left vertical energy-absorbing cant beam 5, right vertical energy-absorbing cant beam 9, lower-left energy-absorbing cant beam 6, bottom right energy-absorbing cant beam 10, also effectively absorb the energy of collision, greatly reduced the impact that collision causes.The design of safety collision space D, the serious consequence that can effectively protect lorry casing or tank body or crew module's 1 rear end to avoid the intrusion because of rear car to produce.
When the biasing rear-end collision occurs when, put with left avertence and to knock into the back as example, the plane that is formed by left column 4 and rear anti-crash entablatrance 11, rear anti-crash center member 12, rear anti-crash cross sill 13, can effectively increase area of thrust surface, thereby greatly increase the area of thrust surface of vehicle (the rear car) that knock into the back, effectively bring into play the effect (intensity of general lorry front end operator's compartment is less) at its anterior crumple energy-absorbing position.Simultaneously, the common energy-absorbing function of upper left energy-absorbing cant beam 3, left vertical energy-absorbing cant beam 5, lower-left energy-absorbing cant beam 6 has also effectively absorbed the energy that collides, and greatly reduces the impact that collision causes.Left outside crashproof cant beam 2 can increase resists the overbalance impulse force that offset collision brings, and effectively protects lorry casing or tank body or crew module's 1 left back end.Lorry casing or tank body or crew module's 1 left back end can be effectively protected in the design of safety collision space D, the serious consequence of avoiding the intrusion because of rear car to produce.
More than embodiment of the present utility model is had been described in detail; those of ordinary skill in the art will be appreciated that; the thought that provides according to the utility model; all will change on the concrete embodiment of the utility model and field of application, these changes also should be considered as protection domain of the present utility model.
