Description
Technical field
The present invention relates to automobile manufacturing field, particularly one cross-country battlebus lightweight back axle fixed support.
Background technology
Along with " energy-conserving and environment-protective " more and more become the topic of extensive concern, lightweight is also widely applied to general-utility car field, can also have outstanding fuel-economizing performance while raising is handling.The oil consumption of automobile depends primarily on the discharge capacity of driving engine and the total mass of automobile, under maintenance Integral automobile quality, performance and the constant prerequisite even optimized of cost, reduce automobile own wt can improve horsepower output, reduce noise, promote handling, reliability, improve the speed of a motor vehicle, reduce oil consumption, reduce discharge amount of exhaust gas, promote safety.Have research numerical monitor, if vehicle complete vehicle weight reduces by 10%, fuel efficiency can improve 6%-8%; If rolling resistance reduces 10%, fuel efficiency can improve 3%; If the driving efficiency of the device such as vehicle bridge, change-speed box improves 10%, fuel efficiency can improve 7%.Auto body accounts for 30% of automobile total mass, under no-load condition, and the oil consumption of about 70% is used on body quality.Therefore, vehicle body lightens all of great advantage for the fuel economy of car load, wagon control stability, crash survivability.
Back axle, just refers to the rear drive shaft component part that vehicle power transmits.It is made up of two half-bridges, can implement half-bridge differential motion.Meanwhile, it is also used to support wheel and the device being connected rear wheel.If the vehicle that propons drives, so back axle is only just follow-up bridge, only plays the effect of carrying.If propons is not drive axle, so back axle is exactly drive axle, at this time also plays to drive and slow down except carrying effect to also have the effect of differential, if four wheel drive, generally before back axle, be also furnished with a part-time case.Back axle is divided into overall bridge and half-bridge.Dependent suspension joined by overall bridge, and as plate spring suspension brackets, half-bridge joins independent suspension, as McPherson strut.
For in cross-country commander's battlebus for back axle being fixed on the fixed support of after-frame, because it is for fixing and support back axle and use, therefore its Thickness Ratio is thicker, and overall weight is heavier, can reach 48kg.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cross-country battlebus lightweight back axle fixed support, on the basis ensureing fixed support intensity, can reduce support bracket fastened overall weight.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of cross-country battlebus lightweight back axle fixed support, and its innovative point is: comprise a fixed support main body, and this fixed support main body is made up of jointly back axle linkage section and after-frame linkage section;
Described back axle linkage section comprises a rear axle connecting plate, this rear axle connecting plate is rectangle shape, and there is in the side of this rear axle connecting plate the U-shaped opening A of an appearance back axle embedding, upperly at rear axle connecting plate be also symmetrically distributed with two groups of bolt hole groups with the two ends of U-shaped opening A, often organize bolt hole group and jointly form along U-shaped opening A long axis direction well-distributed bolt hole by three;
Described after-frame linkage section comprises and is arranged on rear axle connecting plate side and the after-frame connecting panel A connected successively from U-shaped opening A place, after-frame connecting panel B, after-frame connecting panel C and after-frame connecting panel D, and the length of after-frame connection version A is less than the length of after-frame connecting panel C, after-frame connecting panel A has a waist through hole A be connected with U-shaped opening A, after-frame connecting panel B and after-frame connecting panel D all have a U-shaped opening B, after-frame connecting panel C has a waist through hole B, the bottom of described after-frame connecting panel A and after-frame connecting panel C is connected to mount pad A, mount pad C, described mount pad A is rectangle shape, mount pad A has four along mount pad A long axis direction and the bolt hole of column distribution, mount pad C is echelon form, a bolt hole is distributed with in four corners of mount pad C, also there is at the medium position of mount pad C the bolt hole of three distributions in triangular shape simultaneously.
Further, described mount pad A has an arc groove A, arc groove C respectively with medium position mount pad C being positioned at a relative side.
Further, described fixed support entire body is made up of high-strength and high ductility iron base composite material.
The invention has the advantages that: in the present invention, on the basis ensureing fixing rack structure intensity, by changing support bracket fastened version, by opening U-shaped opening and waist through hole on after-frame linkage section, support bracket fastened overall weight is made to be relieved to 40.1kg by original 48kg, weight-loss ratio reaches 16.4%, thus reaches the object alleviating fixed support weight.
By the setting of arc groove A and arc groove C, can on the basis ensureing structural strength, actv. decreases the weight of mount pad, finally can alleviate the weight of support bracket fastened entirety; Fixed support entirety is made by high-strength and high ductility iron base composite material, support bracket fastened mechanical property can be improved more than 50%.
