Abstract

A novel chassis of a carriage of a truck comprises a longitudinal beam with a variable cross section, a crossbeam, an iron brace, an angle iron support plate and side straps. A portion, which is positioned at a center shaft of a rear axle, of the longitudinal beam of the chassis of the carriage of the heavy-duty truck is heightened, local carrying capacity is increased, simultaneously, excessively large increase of the dead weight of the truck is avoided, and deformation of the longitudinal beam and cracking of a welded junction are prevented.

Description

Chassis, novel wagon compartment

Technical field

The utility model relates to the motor-vehicle chassis technology, especially chassis, novel wagon compartment.

Background technology

The load-carrying capacity on chassis, boxcar is directly connected to the transportation safety of vehicle, and the present vehicle of large cargo transportation on the highway is often owing to transship or the time overlength chassis, compartment takes place is snapped, is out of shape.Particularly upright curved under back axle center shaft position occurs, directly have influence on the vehicle load-carrying capacity, reduce Transport Safety.Often run into this situation, the car owner is compelled to change No. 25 I-beam sections and comes braced chassis intensity.But the compartment deadweight after the replacing has increased about 1000 kilograms of steel weight, strengthens compartment cost and operation cost, brings economical burden to the car owner.

Summary of the invention

In order to overcome heavy amount truck chassis overload or time overlength the chassis, compartment takes place and snap, be out of shape, the utility model provides chassis, a kind of novel wagon compartment.Adopt the variable section longeron, reach and strengthen longeron local load-carrying capacity and resistance to deformation intensity, reduce the purpose of dead weight of vehicle.

The technical scheme that the utility model solves its problem is to be made up of variable section longeron, crossbeam, support iron, angle bar stay bearing plate, sideband, and two variable section longerons adopt manganese steel plate to manufacture I-beam section, and two narrow sections height are 160 centimetres before and after the longeron; The middle part is protruding, highly is 260 centimetres, and the boss rear and front end is a ramped shaped; Crossbeam is processed by channel-section steel, and crossbeam is gone up planar alignment according to truck box chassis each item purposes for two narrow sections in variable section longeron front and back, and the crossbeam bottom surface is gone up the plane with two narrow sections of variable section longeron front and back and cooperated solid welding; Support iron and be made up of big support iron, ramuscule support iron, support iron greatly and adopt the plate iron flanging to process set square, ramuscule support iron cuts into the right angle equilateral triangle by square steel and processes; The ramuscule of each crossbeam points of engagement of two narrow sections support iron is made up of two blocks of horizontal ramuscule support iron and two blocks of vertical ramuscule support iron before and after the variable section longeron, and two blocks of horizontal ramuscule support iron cooperate solid welding with variable section longeron riser and crossbeam lower surface respectively, and two blocks of vertical ramuscule support iron cooperate solid welding with variable section longeron upper surface and crossbeam two side; Four crossbeams that cooperate with variable section longeron intermediate projections position are identical; With wherein one be example, crossbeam is truncated into three sections, a middle segment length; Two sections at two ends are shorter; Middle long beam surface upper and variable section longeron flush, long crossbeam two ends, centre cooperate solid welding with two variable section longeron boss variable section longeron risers, support iron greatly and cooperate with variable section longeron riser and middle long crossbeam lower surface cooperation solid welding; Angle bar supports the backboard wall and cooperates solid welding with crossbeam groove inwall and I-beam section riser; Two sections identical main beam transverses, with one section be example, main beam transverse one end cooperates solid welding with variable section longeron riser; The big iron that supports cooperates with variable section longeron riser and main beam transverse lower surface cooperation solid welding; Angle bar supports the backboard wall and cooperates solid welding with crossbeam groove inwall and variable section longeron riser, and sideband is processed by channel-section steel, and two sidebands cooperate solid welding with every crossbeam two ends.

The beneficial effect of the utility model is: the longeron height is widened in the back axle center shaft position of chassis member in heavy amount boxcar, does not increase too many dead weight of vehicle when strengthening local load-carrying capacity, has prevented the appearance that longeron distortion, weld bond split.
