The shortcomings that body vertical stiffness and intensity are weak, and welding efficiency is low, are easily deformed, and technique is cumbersome.
(2) technical solution
In order to solve the above-mentioned technical problem, the utility model provides a kind of vehicle body bottom frame side bar, including side bar and threshold, institute
It states side bar and the integral structure that threshold is cold roll forming, is connected between the side bar and threshold by junction.
Wherein, the threshold has lug boss.
Wherein, horizontal distance of the lug boss apart from the junction is 30 centimetres.
Wherein, a length of 67.5 centimetres of the lug boss, a height of 35 centimetres.
Wherein, the corner between the junction and the side bar is the fillet of 9 centimetres of radius；The junction and institute
State the fillet that the corner between threshold is 9 centimetres of radius；The corner of the lug boss is the fillet of 9 centimetres of radius.
Wherein, the angle between the threshold and the junction is 83.5 °.
Wherein, the thickness of the side bar is 4 centimetres.
Wherein, the vertical height of the junction is 160 centimetres.
Invention additionally discloses a kind of railcar, the vehicle body bottom frame side bar including the utility model.
(3) advantageous effect
A kind of vehicle body bottom frame side bar and its railcar provided by the utility model, utilize the side bar and threshold of cold roll forming
Integral mechanism, improve the whole vertical stiffness and intensity of side bar by being welded and fixed with threshold instead of side bar in the prior art；

It can be the connection inside two elements.For the ordinary skill in the art, can above-mentioned art be understood with concrete condition
Concrete meaning of the language in the utility model.
As shown in Figure 1, the utility model discloses a kind of vehicle body bottom frame side bar, including side bar 1 and threshold 2, the side bar 1 with
Threshold 2 is the integral structure of cold roll forming, is connected between the side bar 1 and threshold 2 by junction 3.
Specifically, using roll-forming technology on integral structure, transverse curvature is carried out, side bar 1 and threshold 2 is made
Section section bar is connected between the two using junction 3.Substitute is in the prior art separate structure, and weld by side bar and threshold
Way together.
A kind of vehicle body bottom frame side bar provided by the utility model, using the side bar of cold roll forming and the integral mechanism of threshold,
Instead of side bar in the prior art the whole vertical stiffness and intensity of side bar are improved by being welded and fixed with threshold；Reduce welding
Amount, reduces welding deformation；Improve the feasibility of technique.
Wherein, the threshold 2 has lug boss.
Wherein, horizontal distance of the lug boss apart from the junction 3 is 30 centimetres.
Wherein, a length of 67.5 centimetres of the lug boss, a height of 35 centimetres.
Wherein, the corner between the junction 3 and the side bar 1 is the fillet of 9 centimetres of radius；The junction 3
Corner between the lug boss is the fillet of 9 centimetres of radius；The corner of the lug boss is the circle of 9 centimetres of radius
Angle, convenient for cold roll forming.
Wherein, the angle between the threshold 2 and the junction 3 is 83.5 °
Wherein, the thickness of the side bar 1 is 4 centimetres.
Wherein, the vertical height of the junction 3 is 160 centimetres.
Invention additionally discloses a kind of railcar, the vehicle body bottom frame side bar including the utility model.
A kind of vehicle body bottom frame side bar and its railcar provided by the utility model, utilize the side bar and threshold of cold roll forming
Integral mechanism, improve the whole vertical stiffness and intensity of side bar by being welded and fixed with threshold instead of side bar in the prior art；
Reduce welding capacity, reduce welding deformation；Improve the feasibility of technique.
