Mounting hole, upper arm connecting hole is provided with knuckle upper arm.
The outer face corner of the knuckle body offers back-plate mounting hole, the outer face of knuckle body respectively
On be further opened with caging bolt mounting hole.
The brake air chamber bracket mounting hole of installation brake air chamber bracket is offered on the knuckle body.
The knuckle underarm is integrated using forging type with knuckle Ontology integration, on knuckle body, knuckle
Arm and knuckle underarm are formed using austempered ductile iron casting.
The lower end of the stub mounting hole is provided with the master pin closure installation position of installation master pin closure.
The beneficial effects of the utility model are：
1. the utility model eliminates underarm connecting bolt by together with knuckle underarm and knuckle body effective integration
And locking nut, and forging type machine-shaping is employed, the bulk strength of knuckle is ensure that, while knuckle axle journal is interior
Portion is arranged to hollow structure, is effectively reduced the overall weight of knuckle.
2. the utility model is simple in construction, reduce connecting portion, fault rate is reduced, and is simplified by forging type
Manufacturing process, the bulk strength of knuckle is improved, hollow structure alleviates overall weight used by knuckle axle journal, accords with
Close the requirement of automotive light weight technology.
