Abstract
The invention discloses a big bent arm comprising a connection arm, wherein one end of the connection arm is a hole groove part; upper and lower sides of the hole groove part are provided with circular blind holes and a thin wall is arranged between the upper and lower circular blind holes; the other end of the connection arm is a bowl-shaped groove part and the bowl-shaped groove part is provided with a bowl-shaped groove, wherein the connection arm, the hole groove part and the bowl-shaped groove part are molded by primarily forging; and the axes of the circular blind holes on the hole groove part are vertical to that of the bowl-shaped groove on the bowl-shaped groove part. The big bent arm provided by the invention is rational in structure, convenient for processing and manufacturing, reliable in use, high in cost performance and the like.
Description
Technical field
The present invention relates to a kind of car chassis parts, relate in particular to a kind of big curved boom.
Background technology
The chassis effect is supporting, installation automotive engine and each parts thereof, assembly, forms the moulded of automobile, and accepts the power of driving engine, makes automobile produce motion, guarantees cruising.The chassis is made up of transmission system, running device, steering system and brake system four parts.Big curved boom is a safety component wherein, and structure design of these parts itself and crudy directly influence the supporting and the transmission performance on chassis.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this invention is to provide a kind of big curved boom, have rational in infrastructure, make things convenient for processing and manufacturing, use reliable, cost performance advantages of higher.
In order to reach above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of big curved boom comprises a connecting arm, and connecting arm one end is a hole slot portion; The upper and lower surface of hole slot portion is circular blind hole; Be thin-walled between two circular blind holes up and down, the connecting arm other end is the bowl-type slot part, and the bowl-type slot part is provided with a bowl-type groove; Wherein, said connecting arm, hole slot portion and forging molding of bowl-type slot part; The axis of the circular blind hole of said hole slot portion and the axis of bowl-type slot part bowl-type groove are perpendicular.
As preferably, the line of centers of said connecting arm forms vault in the stage casing, and with perpendicular plane, this vault plane in form Z-shaped distortion.
As preferably, said connecting arm is formed with reinforced rib at crooked position.
The present invention has been owing to adopted above technical scheme, have rational in infrastructure, make things convenient for processing and manufacturing, use reliable, cost performance advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Do a detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Embodiment 1:
A kind of big curved boom as shown in Figure 1; Comprise a connecting arm 1, connecting arm 1 one ends are hole slot portion 2, and the upper and lower surface of hole slot portion 2 is circular blind hole; Be thin-walled 22 between two circular blind holes up and down; Connecting arm 1 other end is a bowl-type slot part 3, and bowl-type slot part 3 is provided with a bowl-type groove, said connecting arm 1, hole slot portion 2 and 3 forging moldings of bowl-type slot part.Thin-walled 22 is got through when mounted, convenient like this manufacturing and installation.The bowl-type groove is used to be provided with sensor.
In the present embodiment; As shown in Figure 2, the line of centers 11 of said connecting arm 1 forms vault in the stage casing, and with perpendicular plane, this vault plane in form Z-shaped distortion (as shown in Figure 1); Rational in infrastructurely so limited space, chassis be can make full use of, supporting and transmission effect guaranteed.Said connecting arm 1 is formed with reinforced rib at crooked position, to guarantee the supporting Joint strenght.The axis 21 of said hole slot portion 2 circular blind holes is perpendicular with the axis 31 of bowl-type slot part 3 bowl-type grooves.
