Put in the both sides of longitudinal centre line, so that the connection between steering assembly and subframe body 21 is more solid and reliable.
As shown in Fig. 2 can be set on the lateral surface of one end of hollow installation portion 12 on two trailing arms of collision prevention girders 11
Indent reinforcement structure 14 is equipped with, so as to be effectively improved the intensity of collision prevention girders 11, and causes that swing arm there are enough spaces,
Gap of the swing arm at limit of sports record position and between collision prevention girders 11 is increased, swing arm is greatly reduced and is occurred with collision prevention girders 11
The risk of interference；Lightening hole can be provided with subframe body 21 such that it is able to substantially reduce weight, and at the design initial stage,
Subframe body can be met by increasing the thickness of indent reinforcement structure 14 or any adjustment weakness according to analysis result
21 intensity and rigidity.
Auxiliary frame structure of the invention, its collision prevention girders 11 are rolled, high using the U-shape structure of integral type by high strength steel plate
The welding of frequency solder technology, bending machine bending, hydraulic expanding type are formed, and ultimately form integral structure.Subframe body 21 can be
The integral structure of aluminium alloy casting.Due to being welded with stabiliser bar assembly peace between the upper and lower plate of subframe in the prior art
Dress project-welding nut, steering assembly installation bolt sleeve pipe and suspension installation bolt sleeve pipe；For stabiliser bar mounting structure, using convex
Weldering nut is welded and fixed with subframe upper plate, so as to destroy the flatness of crab bolt installation place on subframe so that spiral shell
There is empty tight phenomenon in bolt, vehicle is in bad working environments condition downward driving, it may appear that Bolt Torque wear-out failure, enters after torque is urgent
And influence vehicle security；For steering assembly installation bolt sleeve structure, spot welding is carried out using sleeve pipe and subframe upper plate
It is connected, equally destroys the flatness of subframe upper plate, subframe lower plate cannot be fixed with sleeve pipe by welding manner, only
Can realize connecting by frock, installation accuracy herein is poor, influences the installation accuracy of steering gear, and bolt passes through two-layer metal plate
Part and sleeve pipe can realize connection, and this just needs to provide larger power consumption and metal plate and casing deformation, only small part power
For stationary deflector assembly, torque decay is easily caused.And stabiliser bar assembly of the invention installs sleeve pipe 25, steering assembly peace
Mounting surface in tubing 26, swing arm back bush fixed plate 23, engine mounting mounting bracket 22 passes through process for machining reality
It is existing so that the flatness precision of the mounting surface is greatly improved, and is solved flatness at the welding of sheet metal parts in the prior art and is not reached
The problem of design requirement, and then the empty tight and torque attenuation problem of Bolt Torque is solved, and improve the rigidity and peace of installation place
Dress precision, improves vehicle performance and security.
Collision prevention girders of the invention 11 are contrasted with existing scheme, and being welded by six pieces of original metal plate punching parts, it is whole to be optimized for
Body formula structure, reduces mould development quantity, eliminates the exploitation of complicated welding tooling, shortens the construction cycle, saved into
This, reduces its assembly weight, reduces fuel consumption and vehicle comfortableness；Meanwhile, solve batch production welding uniformity
Unmanageable problem, improves the quality of product.The auxiliary frame structure that the present invention is provided is welded to connect without any, passes through
Process for machining is molded, and substantially increases assembly precision, solves installation accuracy difference or torque decay that sheet metal component Zona transformans comes
The problems such as, meanwhile, welding tooling is saved, solve the problems, such as to weld the weld cracking that uniformity difference causes, improve auxiliary frame structure
Bulk strength and rigidity.
The above is only the preferred embodiment of the present invention, it should be pointed out that these embodiments are merely to illustrate this
Invention rather than limitation the scope of the present invention, and, after present disclosure has been read, relevant technical staff in the field
Various changes or modification can be made to the present invention, these equivalent form of values equally fall into the application appended claims and limited
Scope.
