Description
Technical field
This utility model relates to a kind of knuckle arm, particularly relates to a kind of automobile front axle knuckle arm, belongs to technical field of automobile.
Background technology
At present, knuckle arm is the important connection member on automobile front axle, and knuckle arm is bolted on knuckle, and knuckle arm needs have certain intensity.Traditional knuckle arm weight is relatively big, and knuckle arm does not carry out on the premise of proof strength effective loss of weight, and light-weight design is in poor shape, is unfavorable for alleviating the weight of knuckle arm itself and the weight of whole automobile front axle assembly.
Summary of the invention
The purpose of this utility model is bigger for existing automobile front axle knuckle arm weight, do not carry out effective loss of weight, light-weight design is in poor shape, it is unfavorable for alleviating defect and the deficiency of whole automobile front axle assembly weight, there is provided a kind of rational in infrastructure, knuckle arm has carried out on the premise of proof strength effective loss of weight, and light-weight design situation is good, is conducive to alleviating a kind of automobile front axle knuckle arm of whole automobile front axle assembly weight.
For achieving the above object, technical solution of the present utility model is: a kind of automobile front axle knuckle arm, including knuckle arm body, installing hole is offered on knuckle arm body, the outer face of installing hole is installed surface, and the inner side end of installing hole is stationary plane, and described knuckle arm body offers lightening grooves on the inner surface of installing hole one end, the degree of depth of lightening grooves is the 1/5-3/5 of knuckle arm body thickness, the 1/2-3/4 that a width of arm of lightening grooves is wide.
Described lightening grooves inner surface between two installing holes extends in the middle part of the outer surface of knuckle arm body.
It is provided with curved boom position on described knuckle arm body.
The beneficial effects of the utility model are:
1. this utility model offers lightening grooves at the outer surface of the side of knuckle arm body, lightening grooves extends in the middle part of the outer surface of knuckle arm body, and the depth and width selected by lightening grooves book can carry out effective loss of weight to knuckle arm on the premise of proof strength.
2. this utility model is rational in infrastructure, uses this light-weight design to not only save material, and is conducive to alleviating the weight of knuckle arm itself and the weight of whole automobile front axle assembly, and then promotes the performance of vehicle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side schematic view of the present utility model.
Fig. 3 is the left view of Fig. 2.
In figure: knuckle arm body 1, installing hole 2, installed surface 3, stationary plane 4, curved boom position 5, lightening grooves 6, loss of weight groove width d, arm width D.
Detailed description of the invention
Illustrate with detailed description of the invention, this utility model to be described in further detail below in conjunction with accompanying drawing.
See Fig. 1 to Fig. 3, a kind of automobile front axle knuckle arm of the present utility model, including knuckle arm body 1, installing hole 2 is offered on knuckle arm body 1, the outer face of installing hole 2 is installed surface 3, and the inner side end of installing hole 2 is stationary plane 4, it is characterised in that: described knuckle arm body 1 offers lightening grooves 6 on the inner surface of installing hole 2 one end, the degree of depth of lightening grooves 6 is the 1/5-3/5 of knuckle arm body 1 thickness, and loss of weight groove width d is the 1/2-3/4 of arm width D.
The described lightening grooves 6 inner surface between two installing holes 2 extends in the middle part of the outer surface of knuckle arm body 1.
It is provided with curved boom position 5 on described knuckle arm body 1.
As shown in Figure 1, offering installing hole 2 on knuckle arm body 1, the outer face of installing hole 2 is installed surface 3, and the inner side end of installing hole 2 is stationary plane 4, installed surface 3 is close to knuckle, and utilizes bolt to pass through installing hole 2 to be fixed on knuckle by knuckle arm body 1.Being additionally provided with curved boom position 5 on knuckle arm body 1, knuckle arm is easy to connect steering linkage.
This utility model is in order to alleviate the weight of workpiece, reach the purpose of light-weight design, offering lightening grooves 6 on the inner surface of installing hole 2 one end at knuckle arm body 1, the lightening grooves 6 inner surface between two installing holes 2 extends in the middle part of the outer surface of knuckle arm body 1.The inner surface of knuckle arm body 1 i.e. knuckle arm install after surface downward, after knuckle arm body 1 is installed, lightening grooves 6 is positioned at bottom rather than is positioned at upper surface upward, so can avoid groove internal water accumulation.
The degree of depth of lightening grooves 6 is the 1/5-3/5 of knuckle arm body 1 thickness, loss of weight groove width d is the 1/2-3/4 of arm width D, using this depth and width knuckle arm can carry out on the premise of proof strength effective loss of weight, loss of weight amount of the present utility model can arrive the 8%-15% of knuckle arm gross weight.This light-weight design not only saves material, and is conducive to alleviating the weight of knuckle arm itself and the weight of whole automobile front axle assembly, and then promotes the performance of vehicle.
