Abstract
The utility model provides a light truck frame assembly, including longeron and connect behind first crossbeam, second crossbeam, the engine between two longerons suspension crossbeam, transmission shaft suspension crossbeam, back suspension front beam, back suspension rear frame crossbeam, tail crossbeam, its characterized in that: the engine rear suspension cross beam and the transmission shaft suspension cross beam are of a crocodile mouth-shaped structure and comprise a cross beam upper piece and a cross beam lower piece, the top of the cross beam lower piece is connected with the cross beam upper piece, and two ends of the cross beam upper piece and the cross beam lower piece are connecting edges connected with the longitudinal beam; the connecting edge of the upper piece of the cross beam is connected with the upper part of the longitudinal beam, and the connecting edge of the lower piece of the inverted U-shaped cross beam is connected with the lower part of the longitudinal beam. The front and rear beams of the rear suspension adopt channel beams and are connected with the longitudinal beam through wing edge type structural plates.
Description
Technical field
The utility model relates to a kind of light truck frame assembly, belongs to a kind of of automobile chassis frame system.
Background technology
Light truck adopts the variable section longeron to be connected with the Duo Gen crossbeam and the local frame assembly that pastes brace panel more on the market, this frame assembly causes because of beam structure and layout are unreasonable that vehicle frame serious cracking, car load vibration are excessive, operator's compartment and container are crooked, brace panel too much causes the vehicle frame quality to lay particular stress on, it is too much that the variable section longeron drops into mould, problems such as it is many to cause bicycle frame assembly cost height, change wheelbase vehicle vehicle frame to inject capital into, and the manufacturing cycle is long.
Summary of the invention
The purpose of this utility model designs a kind of real lightweight, raising cost performance, improves the light truck frame assembly of load.
The technical solution of the utility model: light truck frame assembly of the present utility model comprises longeron and is connected first crossbeam, second crossbeam, back suspension device of engine crossbeam, transmission shaft between two longerons suspend crossbeam, rear suspension front cross rail, rear suspension after cross member, transom beam, its back suspension device of engine crossbeam and the transmission shaft crossbeam that suspends adopts crocodile mouth shape structure, comprise sheet under crossbeam last slice and a few font crossbeams, the top of sheet is connected with crossbeam last slice under a few font crossbeams, and the two ends of sheet are and longeron bonded assembly connection side under crossbeam last slice and a few font crossbeams; The connection side of crossbeam last slice is connected with the top of longeron, and the connection side of sheet is connected with the bottom of longeron under a few font crossbeams.
The forward and backward crossbeam of rear suspension adopts channel-section rail and is connected with longeron by wing limit formula structural slab.
Advantage of the present utility model:
Vehicle frame of the present utility model is in light weight, and is simple in structure, easy for installation, safe and reliable, and load-carrying capacity is strong, spreads out few cost performance height that disappears, the intensity height, and the bending resistance resistance to shear is strong, and torsional stiffness is good.On light truck, realize to adopt the straight longeron of uniform cross section of proprietary material DL510 longeron steel, seven alternate layouts of channel crossbar crocodile mouth shape crossbeam, all exploitations of the trapezium structure frame assemblys of riveted joint of beam in length and breadth, reach the frame assembly lightweight, manufacturing cycle weak point, optimality price ratio, the purpose that load-carrying capacity is strong.

The specific embodiment
As Fig. 1: light truck frame assembly of the present utility model comprises longeron 3 and is connected first crossbeam 1, second crossbeam 2, back suspension device of engine crossbeam 4, transmission shaft between two longerons suspend crossbeam 5, rear suspension front cross rail 6, rear suspension after cross member 7, transom beam 8.
Suspend crossbeam 5 of back suspension device of engine crossbeam 4 and transmission shaft adopts crocodile mouth shape structures.
Following back suspension device of engine crossbeam 4 specifies the suspend structure of crossbeam 5 of back suspension device of engine crossbeam 4 and transmission shaft for example:
As Fig. 2, Fig. 3, Fig. 4, Fig. 5, back suspension device of engine crossbeam 4 comprises sheet 4b under crossbeam last slice 4a and a few font crossbeam, the top 4b1 of sheet 4b and crossbeam last slice riveted joint under a few font crossbeams, the two ends of sheet are and longeron bonded assembly connection side under crossbeam last slice and a few font crossbeams; The connection side 4a1 of crossbeam last slice 4a and the riveted joint of the top of longeron 3, the bottom of the connection side 4b2 of sheet 4b and longeron 3 riveted joint under a few font crossbeams.The vibrating effect of this structural damping driving engine is good, and the structure of sheet 4b can be assembled the change speed gear box of various width between centerss under a few font crossbeams of while, is convenient to pipe line arrangement;
Longeron adopts proprietary material DL510 EQL-27 longeron steel, is the straight longeron of uniform cross section flute profile, shortens the manufacturing cycle, reduces and spreads out the cost that disappears, and bending strength is big, is beneficial to pipe line arrangement;
First crossbeam and second crossbeam adopt channel-section rail, satisfy reverse with the bending strength performance under do not adopt the longeron brace panel;
Rear suspension front cross rail 6, rear suspension after cross member 7 adopt channel-section rail and are connected with longeron 3 by wing limit formula structural slab, and torsional stiffness is good, is convenient to pipe line arrangement.
As Fig. 6: 6a is wing limit formula structural slab.
Crossbeam is connected fabrication tool and frock less investment with the riveted joint of the longeron edge of a wing.
Claims (2)
1. light truck frame assembly, comprise longeron and be connected first crossbeam, second crossbeam, back suspension device of engine crossbeam, transmission shaft between two longerons suspend crossbeam, rear suspension front cross rail, rear suspension after cross member, transom beam, it is characterized in that: back suspension device of engine crossbeam and the transmission shaft crossbeam that suspends adopts crocodile mouth shape structure, comprise sheet under crossbeam last slice and a few font crossbeams, the top of sheet is connected with crossbeam last slice under a few font crossbeams, and the two ends of sheet are and longeron bonded assembly connection side under crossbeam last slice and a few font crossbeams; The connection side of crossbeam last slice is connected with the top of longeron, and the connection side of sheet is connected with the bottom of longeron under a few font crossbeams.
