Description
Technical field
This utility model belongs to cargo vehicle technical field, and specifically, more particularly to a kind of longeron of cargo vehicle is total
Into.
Background technology
At present, cargo vehicle longeron is made up of open " u "-shaped groove upward, and the top of " u "-shaped groove outwards turns down formation and turns over
Side.Existing longeron front end upwarps, when being collided, it is impossible to efficiently transmit energy from front to back, and energy-absorbing effect is bad, no
Beneficial to the raising of complete automobile collision passive security performance.
Utility model content
Technical problem to be solved in the utility model is that a kind of longeron of the good cargo vehicle of energy-absorbing effect of offer is total
Into.
The technical solution of the utility model is as follows：A kind of longeron assembly of cargo vehicle, including the longeron of " u "-shaped channel-shaped,
The open upper end of the longeron turns down to form the first flange in the opposite direction, as longeron is symmetrical set on car body
Have two, therefore in this patent description, with longeron side close to each other be interior, the side that is located remotely from each other be it is outer, it is described to indulge
Beam includes front straightway, top rake section, rear-inclined section and rear straightway from front to back, and the front straightway is along the longitudinal direction in straight
Line arranges that the rear end of front straightway is smooth with the front end of top rake section to be connected, outer rear tilted arrangement, institute before the top rake section
The front end of the rear end and rear-inclined section of stating top rake section smooths, interior rear outer incline arrangement, the rear-inclined before the rear-inclined section
The rear end of section is smooth with the front end of rear straightway to be connected, and the rear straightway is linearly arranged along the longitudinal direction, the rear straight line
The rear portion of section upwarps, and the bottom land of the rear straightway front portion, rear-inclined section, top rake section and front straightway is respectively positioned on same level
Face；The reinforcement before being fixedly arranged at the front end with of the front straightway, the front reinforcement are made up of the plate body that " u "-shaped bends, it is front plus
Part is open by force is fixedly connected on above front straightway front end down；It is fixed with the groove of the top rake section and rear-inclined section spacious
Reinforcement in mouth " u "-shaped channel-shaped upward, the rear end of the interior reinforcement extend to rear-inclined Duan Yuhou straightways and smooth and be connected
Position, leave spacing between the " u "-shaped groove inner bottom of the bottom of the interior reinforcement and longeron.
Using said structure, longeron is arranged to front straightway, top rake section, rear-inclined section and rear straightway, and straight after making
The rear end of line segment upwarps, and makes the bottom land of rear straightway front portion, rear-inclined section, top rake section and front straightway be respectively positioned on same level
