Abstract
The utility model relates to a novel front underrun protection device of a commercial vehicle. The novel front underrun protection device is composed of a front underrun protection cross beam welding assembly, connecting bolts, front underrun protection supports and a vehicle frame assembly. The novel front underrun protection device is characterized in that the front underrun protection supports are triangular; the tops of the front underrun protection support are fixedly connected with the front ends of steel beams on two sides of the vehicle frame assembly; the connecting bolts are arranged at the front ends of the front underrun protection supports; two ends of the front underrun protection cross beam welding assembly are fixedly connected with the ends of cross beams; front underrun protection connecting board welding assemblies are arranged at the positions, corresponding to the front underrun protection supports on two sides of the vehicle frame assembly, of the inner side of the front underrun protection cross beam welding assembly; nuts are welded on the front underrun protection connecting board welding assemblies; and the front underrun protection cross beam welding assembly is fixedly connected with the vehicle frame assembly through the connecting bolts. The front underrun protection supports are formed by the two groove-shaped cross beams in a stagger and butt welding mode, enough support is ensured when the cross beams are under strong impact, flexural performance of the cross beams can be increased in the premise of equal section width, and the ends welded at two sides of each cross beam can reduce damage of head-on impact to staff.
Description
Technical field
The utility model relates to a kind of novel commercial vehicle/comm..vehicle front underrun protection device, belongs to commercial vehicle/comm..vehicle passive security protective device field.
Background technology
Annual because of traffic accident takes place frequently, cause vehicle and personnel's loss huge.When especially between car and commercial vehicle/comm..vehicle head-on crash taking place, because of passenger-car chassis is low, car pierces the preceding bottom of commercial vehicle/comm..vehicle and causes car crash under enormous impact power.For guaranteeing occupant safety, reduce the injury that vehicle causes the occupant when bumping, improve the passive satety of vehicle, the preceding protective device with safeguard function is installed on car load is had extremely important property.
Summary of the invention
The purpose of this utility model provides a kind of novel commercial vehicle/comm..vehicle front underrun protection device, protective stent is formed by the staggered butt welding of two channel crossbars under before it, can guarantee that crossbeam has enough supports under intense impact, under the prerequisite of equal section width, can increase the anti-bending strength of crossbeam; The termination of crossbeam both sides welding reduces under the frontal impact injury to personnel.It can prevent that when vehicle frontal collision vehicle from piercing, and also can protect the occupant safety on other vehicle, has improved the car load passive satety.
The technical solution of the utility model is achieved in that a kind of novel commercial vehicle/comm..vehicle front underrun protection device, by the preceding crossbeam of protection down welding assembly, tie bolt, preceding protective stent down, frame assembly is formed, it is characterized in that: preceding protective stent is triangular in shape down, captive joint with the front end of frame assembly both sides girder steel in preceding protective stent top down, preceding protective stent front end down has tie bolt, the preceding crossbeam of protection down welding captive joint crossbeam termination, assembly two ends, there is the preceding connecting panel of protection down welding assembly the position of protective stent under before the inboard corresponding frame assembly both sides of the preceding crossbeam of protection down welding assembly, be welded with nut on the preceding connecting panel of the protection down welding assembly, the preceding crossbeam welding assembly that protects is down captiveed joint with frame assembly by tie bolt.
Good effect of the present utility model is that its preceding protective stent is down formed by the staggered butt welding of two channel crossbars, can guarantee that crossbeam has enough supports under intense impact, can increase the anti-bending strength of crossbeam under the prerequisite of equal section width; The termination of crossbeam both sides welding reduces under the frontal impact injury to personnel.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is a preceding protective stent constructional drawing down of the present utility model.
Fig. 3 is the preceding crossbeam of a protection down welding assembly structure chart of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: as Fig. 1,2, shown in 3, a kind of novel commercial vehicle/comm..vehicle front underrun protection device, by the preceding crossbeam of protection down welding assembly 1, tie bolt 2, preceding protective stent 3 down, frame assembly 4 is formed, it is characterized in that: preceding protective stent 3 is triangular in shape down, captive joint with the front end of frame assembly 4 both sides girder steels in preceding protective stent 3 tops down, preceding protective stent 3 front ends down have tie bolt 2, the preceding crossbeam of protection down welding captive joint crossbeam termination, assembly 1 two ends 6, there is the preceding connecting panel of protection down welding assembly 5 position of protective stent 3 under before inboard corresponding frame assembly 4 both sides of the preceding crossbeam of protection down welding assembly 1, be welded with nut on the preceding connecting panel of the protection down welding assembly 5, the preceding crossbeam welding assembly 1 that protects is down captiveed joint with frame assembly 4 by tie bolt 2.
As shown in Figure 1, by tie bolt 2 the preceding crossbeam of protection down welding assembly 1 is connected with preceding protective stent 3 down, preceding protective stent 3 down is connected with frame assembly 4 by bolt.
As shown in Figure 3, the preceding crossbeam of protection down welding assembly about 1 respectively is welded with crossbeam termination 6, and protect connecting panel welding assembly 5 down before about the inclined to one side medium position of the preceding crossbeam of protection down welding assembly 1 inboard, respectively being welded with, be welded with nut on the preceding connecting panel of the protection down welding assembly 5, preceding protective stent 3 down can pass through tie bolt 2 and be connected with the preceding connecting panel of protection down welding assembly 5.
