Abstract
The invention discloses a rear guardrail device of a truck, and relates to the technical field of automobile manufacturing. The rear guardrail device comprises a frame longitudinal beam of the truck, a support and a rear cross beam, wherein the support is fixed to the frame longitudinal beam; the rear cross beam is connected with the support through a connecting rod; the rear cross beam is formed by a front guard plate, a rear guard plate and an elastic component arranged between the front guard plate and the rear guard plate. According to the rear guardrail device of the truck, disclosed by the invention, the problems that after an automobile is in rear-end collision with the truck, strike energy cannot be absorbed by a rear guardrail of the truck, and great loss is caused to the automobile are solved.
Description
Technical field
The present invention relates to field of automobile, especially a kind of rear protective guard device for truck.
Background technology
The chassis of the more general automobile in chassis of truck is high, and when automobile and truck knock into the back, often automobile can directly creep at the bottom of the car of truck, causes great personal injury and property damage; For this reason, country has put into effect truck rear protective guard national standard specially, requires that all trucies dispatched from the factory all will install the rear protective guard meeting national standard; The rear protective guard of the truck of general motor plant production is all the afterbody being fixedly mounted in truck at present, this rigidity is better, but shortcoming is that truck is once the truck that knocks into the back, huge Impact energy all acts on automobile head and tailstock of truck, the energy clashed into is not absorbed by the rear protective guard of truck, result is that automobile head is subject to fierce shock and causes heavy losses, the even injures and deaths of personnel.
Summary of the invention
The object of this invention is to provide a kind of truck rear protective guard device, it can solve after automobile and truck knock into the back, and Impact energy cannot be absorbed by truck rear protective guard, causes automobile to be subject to the problem of cataphoretic failure.
In order to solve the problem, the technical solution used in the present invention is:
This truck rear protective guard device, the chassis side rail comprising truck and the support be fixed on described chassis side rail, also comprise after cross member; Described after cross member is connected with described support by connecting rod; Described after cross member is made up of font lower shroud, rear backplate and the elastomeric element be arranged between described font lower shroud and rear backplate.
In above technical scheme, further scheme is: described font lower shroud and rear backplate are the bending plate be oppositely arranged, and are provided with connecting panel between described font lower shroud and rear backplate.
Further: described elastomeric element is spring.
Further: the raw parts of described bullet are rubber pad.
Further: described connecting rod is divided into connecting rod, middle connecting rod and lower link three groups, often group is two, and middle connecting rod is wherein arranged with described after cross member is vertical in horizontal surface.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, rear protecting crossbeam of the present invention takes twin beams to add the structure of spring, makes the existing certain rigidity of the rear protective guard of an arrangement truck have again suitable elasticity;
2, the present invention is when automobile generation rear-end collision, and after cross member can absorbing impact energy to greatest extent, and the loss that automobile is subject to is down to minimum.

Fig. 1 is front view of the present invention.
Fig. 2 is the cutaway view of Fig. 1 at A-A line.
Fig. 3 is the cutaway view of embodiment 2 at A-A line.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described: as shown in Fig. 1 ~ Fig. 2,
Embodiment one: this truck rear protective guard device, the chassis side rail 1 comprising truck and the support 2 be fixed on chassis side rail 1, also comprise after cross member 4; After cross member 4 is welded and fixed by connecting rod 3 and support 2, and connecting rod 3 is divided into connecting rod, middle connecting rod and lower link three groups, and often group is two, and middle connecting rod is wherein arranged with after cross member 4 is vertical in horizontal surface; Be provided with spring between font lower shroud 4-2, rear backplate 4-1, font lower shroud 4-2 and rear backplate 4-1 is the bending plate be oppositely arranged, and is provided with connecting panel 4-3 between font lower shroud 4-2 and rear backplate 4-1, and the thickness of slab of connecting panel 4-3 is less than the thickness of slab of font lower shroud 4-2, rear backplate 4-1.
Embodiment two: as shown in Figure 1, Figure 3, this truck rear protective guard device, between font lower shroud 4-2 and rear backplate 4-1, be provided with rubber pad 4-5 in the present embodiment, all the other are identical with embodiment one.
