After adopting aforementioned improved, transom beam can be assembled by the L shaped crossbeam of two volume less, because the small volume of part does not need large-scale forming mould, has reduced manufacture difficulty and cost of manufacture, simultaneously, the structure of pulling the connecting bore position is converted into double-decker by original single layer structure, has improved the structural strength of pulling the connecting bore position, makes the load-carrying capacity of transom beam obtain enhancing, improve vehicle performance, guaranteed the structural stability between tractor truck and the trailer.
In order further to improve the structural strength of pulling the connecting bore position on the transom beam, the present invention has also done following improvement: be provided with external reinforcing plate for car on the lateral surface at the place, position, overlapping portion of entablatrance and cross sill, external reinforcing plate for car is the plate-like structure that cross-sectional plane takes the shape of the letter U, external reinforcing plate for car is with entablatrance and cross sill double team, be provided with the first connecting bore on the external reinforcing plate for car, the first connecting bore with pull the connecting bore uniform cross section and overlap each other.External reinforcing plate for car with entablatrance and cross sill double team interior, further improved the connective stability between entablatrance and the cross sill, simultaneously, the setting of external reinforcing plate for car also is further converted to three-layer structure so that pull the structure of connecting bore position, and the structure intensity of pulling the connecting bore position is further got a promotion.
In order further to improve the structural strength of pulling the connecting bore position on the transom beam, also can interior brace panel be set at transom beam, concrete scheme is: be provided with interior brace panel on the medial surface at the place, position, overlapping portion of entablatrance and cross sill, interior brace panel is the plate-like structure that cross-sectional plane takes the shape of the letter U, the lateral surface of interior brace panel contacts entirely with the medial surface of transom beam, be provided with the second connecting bore on the interior brace panel, the second connecting bore with pull the connecting bore uniform cross section and overlap each other.Interior brace panel and external reinforcing plate for car can adopt or independent the setting simultaneously, when only in interior brace panel and external reinforcing plate for car, selecting one when arranging, can make the structure of pulling the connecting bore position form three-layer structure, when interior brace panel and external reinforcing plate for car use simultaneously, can make the structure of pulling the connecting bore position form the four-layer structure body.
Same as the prior art, transom beam of the present invention still adopts existing connection mode to be connected with longeron, and concrete connection mode is: the transom beam two ends respectively by left link span be connected link span and be connected with the chassis side rail of both sides; Described left link span is comprised of two blocks of wing plates and connecting panel; Two blocks of wing plates are arranged at respectively the two ends of connecting panel, and two blocks of wing plates are parallel to each other; Two blocks of wing plates and connecting panel are integral structure, and two blocks of wing plates and the formed structure of connecting panel are the plate-like structure that cross-sectional plane takes the shape of the letter U; The medial surface of two blocks of wing plates is connected with downside with the upper side of transom beam end respectively; The lateral surface of connecting panel is connected with the medial surface of chassis side rail; Described right link span structure and left link span are symmetrical.
In order to strengthen the Joint strenght between transom beam and the chassis side rail, the present invention has done following improvement: described wing plate cross-sectional plane is that trapezoidal, trapezoidal upper base width is more than or equal to the transom beam width; Described connecting panel width is more than or equal to the trapezoidal width of going to the bottom; The trapezoidal width of going to the bottom is greater than trapezoidal upper base width; Trapezoidal lower bottom is connected with connecting panel.On the wing plate with the width of transom beam junction less than with the width of longeron junction, this just can be with the Force decomposition of transom beam to larger plane of action, from reducing the application force in the unit area on the longeron, guarantee to strengthen the structural stability between transom beam and the chassis side rail.
With in the prior art in the same manner, the present invention also at place, the position, overlapping portion of entablatrance and cross sill, pull on the structure of the connecting bore left and right sides and respectively be provided with an auxiliary connecting bore, two auxiliary connecting bores and be connected connecting bore for being connected with the structure matching of pulling on the trailer.
Useful technique effect of the present invention is: reduced manufacture difficulty and the cost of manufacture of transom beam, improved the structural strength of transom beam.
