Description
Technical field
The present invention relates to auto parts and components field, particularly relate to a kind of steel-plate main arm.
Background technology
Traditional principal arm adopts cold-rolling steel shaping making or aluminum alloy forged usually, because cold-rolling steel intensity is lower, thus weight is larger, and the parameter of tire can only be regulated by eccentric bolt, although aluminum alloy forged attractive in appearance but hollow owing to not being swaged into, weight can not significantly decline, and these two kinds all need to drop into larger mould, in batches greatly, costly, the racing car of improper small lot multi items.
Summary of the invention
The present invention is intended to solve the deficiencies in the prior art, provides a kind of steel-plate main arm, solves the contradiction between traditional principal arm intensity, weight, cost, is particularly suitable for the performance-oriented racing car of small lot customization.
For realizing above-mentioned technical purpose, the present invention by the following technical solutions, a kind of steel-plate main arm, comprise ball-bearing casing cover, lower bend pipe and upper U-board, upper U-board is located at the top of lower bend pipe, ball-bearing casing is set in the two ends of lower bend pipe, and the middle part of described upper U-board is provided with and twoly subtracts installation main body, the middle part of principal arm by interior L-square, outer bevel board, damping installation sleeve and tiltedly shrouding be arranged symmetrically with composition damping part.
As preferably, described two subtracting installs that main body panel beating is assembled to be welded.
As preferably, described interior L-square, outer bevel board, damping installation sleeve and tiltedly shrouding be arranged symmetrically with composition cross section parts triangular in shape.
As preferably, outer bevel board is located at above oblique shrouding, and described damping installation sleeve runs through oblique shrouding and interior L-square fixes damping part.
As preferably, described damping part is fixed on the top of the both sides of U-board, lower bend pipe.
As preferably, described principal arm adopts cold-rolling steel and solid drawn pipe to make.
As preferably, described ball-bearing casing cover is located at the two ends of U-board simultaneously.
A kind of steel-plate main arm structure of the present invention adopts cold-rolling steel and solid drawn pipe to make, strong light-weight, and can flexural deformation and absorb energy when heavy overload, principal arm and vehicle frame adopt ball-bearing casing to be connected, two subtracting installs that main body panel beating is assembled to be welded, by interior L-square, outer bevel board, damping installation sleeve, oblique shrouding is arranged symmetrically with composition cross section parts triangular in shape, intensity is high, reasonable stress, damping mounting center line is in the bottom of the two ball-bearing casing lines of centres, stabilized conditions can be kept in use procedure, accommodate the main arm structure in double leval jib suspension, load-carrying capacity is strong.
