Abstract
The invention provides a kind of vehicle chassis annex support connection device, strut bar for a fixed vehicle chassis annex the inner is provided with the connector that can be connected and fixed with vehicle crossbeam, connector arranges an internal thread head in the inner of strut bar, the bolt of rear end plate that this internal thread head can pass with vehicle crossbeam fixing threaded hole coincide and spins, and set internal thread head is fixed in the horn-like tube head of strut bar the inner.By a kind of like this bracing frame of structure, tire mud guard is fixed on automotive frame by Absorbable organic halogens failure-free, integral structure is scientific and reasonable, manufacturing process and installation and maintenance very simple, the fixing traditional product of former employing base and multiple bolt can be substituted completely use, have lightweight, cost is low, reliable in quality, can reduce the distinguishing feature of productive costs.
Description
Technical field
The present invention relates to a kind of vehicle body fittings, specifically a kind of vehicle chassis annex support connection device.
Background technology
Vehicle chassis annex, be all through bracing frame and be fastened on vehicle crossbeam uses, traditional vehicle chassis annex adopts by supporter base to divide multiple bolt to be fixedly connected with automotive frame.There is many deficiencies in this traditional product structure: one is many with material, is unfavorable for automotive light weight technology demand for development; Two is that processing technology is complicated, and manufacturing cost is high; Three is that installation and maintenance is inconvenient.This traditional vehicle chassis annex supporting construction, cannot adapt to the technological advance requirement optimizing Integral automobile quality.
Summary of the invention
The object of the invention is to the problems effectively solving above-mentioned existence, a kind of vehicle chassis annex support connection device be provided, have lightweight, structure is simple, cost is low, the feature such as quick for installation, easy to maintenance.
The present invention includes automotive frame, the specific embodiments that technical scheme adopts is as follows:
Strut bar for a fixed vehicle chassis annex the inner is provided with the connector that can be connected and fixed with vehicle crossbeam.
In technique scheme: described connector arranges an internal thread head in the inner of strut bar, the bolt of rear end plate that this internal thread head can pass with vehicle crossbeam fixing threaded hole coincide and spins.
Set internal thread head is fixed in the horn-like tube head of strut bar the inner.
The present invention passes through technique scheme, the annex that can be connected with vehicle chassis to be spun fixing so a kind of structure by bolt of rear end plate by adopting internal thread head and automotive frame, be fixed on vehicle, the integral structure formed very science is simple, manufacturing expense reduces in a large number, weight reduces by 70%, and installation and maintenance is very convenient.Solve the complex structure of prior art existence, cost is high, materials are many, the problems such as unfavorable automotive light weight technology and installation and maintenance inconvenience, the needs of the technical progress of industry such as can substitute existing vehicle accessory bracing frame completely installs and uses, satisfied Automobile Transportation from now on.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the invention will be further described.
Accompanying drawing is structural representation of the present invention.
Detailed description of the invention
Shown in accompanying drawing embodiment: strut bar 1 the inner for fixed vehicle chassis annex is provided with the connector that can be connected and fixed with vehicle crossbeam 2.Connector arranges an internal thread head 4 in the inner of strut bar 1, and the bolt of rear end plate 5 that this internal thread head 4 can pass with vehicle crossbeam 2 fixing threaded hole coincide and spins.Set internal thread head 4 is fixed in the horn-like tube head 3 of strut bar 1 the inner.
During concrete enforcement, described strut bar 1 can select GB round steel pipe to produce, add and man-hour pipe is added hot-expanding pipe reducing and become bell mouth shape tube head 3, internal thread head 4 is built in tube head 3, reusable heat molding process is fixed riveting and is filled, the global shape of strut bar 1 can be arranged respectively by the requirement of automobile model, and the material of the round steel pipe of strut bar 1 and diameter can need to select materials by the configuration of vehicle.
