Description
Technical field
The utility model relates to a kind of left steering jaw.
Background technology
The jaw that turns to of present domestic heavy motor vehicle generally adopts cross assemble, the jaw that turns to of the type can guarantee the normal operation of automobile when the payload ratings goods, and has certain safety factor, but for heavy motor vehicle, sometimes have overload, in the time of in this state operation, will cause safety factor to descend, cause sometimes the distortion, the fracture that turn to jaw.Therefore, need a kind of improved jaw that turns to, so that automobile still has higher safety factor in the lower time of state of overload.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of novel left steering jaw to be provided, and the utility model is to be achieved through the following technical solutions above-mentioned purpose:
A kind of left steering jaw, comprise axis hole (4), upper ear (1), lower ear (2), with axle connecting portion (3), described upper ear (1) is positioned at the top of axis hole (4), lower ear (2) is positioned at the bottom of axis hole (4), described upper ear (1) has upper earhole (1-1), lower ear (2) has lower earhole (2-2), the aperture of described upper earhole (1-1) and lower earhole (2-2) is 40mm, the thickness of described upper ear (1) is 39mm, the thickness of lower ear (2) is 48mm, and the sidepiece of described axis hole (4) has knock hole (5), and the distance L of the centerline hole of described upper earhole (1-1) and lower earhole (2-2) and axle connecting portion (3) end face is 285mm.
The beneficial effects of the utility model:
Left steering jaw of the present utility model, have certain thickness upper ear and lower ear, and the distance of the centerline hole of upper earhole and lower earhole and axle connecting portion end face, so that this twist moment that turns to jaw to bear in the time of work reduces, so that intensity improves, strengthen greatly safety factor, promoted the driving safety performance of automobile.
