Abstract
The utility model provides a self -adaptation rear defence drilling rod device and this commercial car for commercial car, its can through the self -adaptation autoregulation of mechanism realize rear defence drilling rod height the regulation since the rear defence drilling rod of commercial car can not adjust, and the rear defence drilling rod is liftoff can not be too high, it influences whole car departure angle because of the rear defence drilling rod often to make for the trafficability variation. Especially, great type of the carrying cargo vehicle of rear overhang length is more outstanding. Both can satisfy rear defence drilling rod terrain clearance's requirement through this self -adaptation rear defence drilling rod mechanism, can improve whole car departure angle and trafficability characteristic through the self -adaptive control again. Self -adaptation rear defence drilling rod device includes the backup pad, prevents the drilling rod assembly, sells axle, slotted nut, split pin, goes up the backup pad, prevents that the drilling rod assembly links together through round pin axle, slotted nut, split pin, will go up the backup pad again and fix on the frame, has constituted self -adaptation rear defence drilling rod. Realize through the motion of preventing the spout of drilling rod assembly on last backup pad is followed to the round pin axle that the rear defence bores the regulation of height.
Description
Technical field
The utility model relates to a kind of commercial car self adaptation rear defence drilling rod, belongs to field, commercial vehicle/comm..vehicle chassis.
Background technology
The rear defence drilling rod of commercial car, as the vitals of vehicle passive security, is installed on automobile chassis frame afterbody, and because of the consideration of security reason, the height that rear defence drilling rod is installed can not be liftoff too high.Then the terrain clearance of anti-drilling rod affects again the size of vehicle departure angle, affects further the crossing ability of vehicle, and the impact for the longer loading class vehicle of rear overhang is particularly outstanding.In order to solve this contradiction, each main engine plants often need the rear defence drilling rod designing multiple different setting height(from bottom), even sacrifice the crossing ability of vehicle, reach the security requirement meeting rear defence drilling rod.If there is a kind of commercial car self adaptation rear defence drilling rod, by the Automatic adjusument of rear defence drilling rod, while meeting security requirement, the crossing ability of vehicle can not be affected again.As long as such main engine plants design several rear defence drilling rod, the requirement of various just can be adapted to.So main engine plants' product all has certain competitive edge from safety with by aspect of performance.
Utility model content
For deficiency of the prior art, the utility model aims to provide a kind of commercial automotive self-adapting rear defence boring rod set and this commercial vehicle/comm..vehicle, and while meeting the security requirement of vehicle regulation, what improve again vehicle greatly passes through performance.
In order to solve the problem, the technical solution of the utility model is:
A kind of commercial automotive self-adapting rear defence boring rod set, is characterized in that, comprise upper backup pad 2, anti-drilling rod assembly 3, bearing pin 4, fluted nut 5, spring cotter 6;
Two upper backup pads 2 are individually fixed on vehicle frame 1, and upper backup pad 2 is provided with chute, and bearing pin 4 can move in chute, are linked together by anti-drilling rod assembly 3 by bearing pin 4, fluted nut 5, spring cotter 6 with upper backup pad 2;
Anti-drilling rod assembly 3 can around bearing pin 4 along the runner movement on upper backup pad 2.
Further, anti-drilling rod assembly 3 comprises anti-drilling rod and lower supporting plate, and two lower supporting plates connect anti-drilling rod respectively, and lower supporting plate and upper backup pad are fitted at least partly, pass through pinned connection between upper backup pad, lower supporting plate.
Further, by two anti-drilling rod assemblies of pinned connection and vehicle frame between each upper and lower stay bearing plate, wherein first bearing pin is rotationally connected fixing, another bearing pin in chute slidably, the deep-slotted chip breaker that chute shape is is the center of circle with the first bearing pin.
Further, two upper backup pads are bolted on vehicle frame 1 respectively.
Further, anti-drilling rod assembly 3 is welded by anti-drilling rod and lower supporting plate.
Further, upper backup pad 2, lower supporting plate make by high strength steel and form.
Further, described chute is waist shaped hole structure.
A kind of commercial vehicle/comm..vehicle, adopts above-mentioned a kind of commercial car self adaptation rear defence boring rod set.
The utility model device realizes the adjustment of rear anti-drilling height around bearing pin along moving of the chute on upper backup pad by anti-drilling rod assembly.
