In a preferred embodiment of the present invention, the fixing base is composed of a bottom plate, a base, and a fixing base reinforcing plate, the bottom plate is perpendicular to the base, and the fixing base reinforcing plate is clamped and synchronously fixed on the base from both sides of the bottom plate.

In a preferred embodiment of the present invention, the force application base is composed of an extension rod, a force application base and a base reinforcing plate, the extension rod extends outwards from the force application base, and the base reinforcing plate is disposed between the extension rod and the force application base.

In a preferred embodiment of the present invention, at least 2 bosses are further disposed on the bottom plate, and the bosses allow a gap to be formed between the mounting plate and the bottom plate.

In a preferred embodiment of the present invention, the force applying base is further provided with a plurality of base fixing holes for fixing.

The beneficial effects of the utility model reside in that:

the utility model provides a car knuckle intensity and fatigue endurance test frock through mounting panel, fixing base, connecting rod, application of force seat simulation knuckle to hand piece work, simple structure and easy assembly to the realization is arranged by the supplier before whole car experiment by oneself and touches the endurance test result of knuckle, reduces the possibility that the car later stage takes place great design change of making.

Detailed Description

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, the longitudinal direction (X direction) "," lateral direction (Y direction) "," vertical direction (Z direction) "is the term of the space coordinate system in the automobile field, and the above description is a term of art known to those skilled in the art, so as to simplify the description of the present invention, and it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood, however, that the present application may be embodied in many different forms and is not limited to the embodiments described below. It is also to be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, like reference numbers indicate identical or functionally identical elements.

Referring to fig. 1 and 2, the automobile steering knuckle strength and fatigue endurance test tool mainly comprises: mounting plate 10, fixing base 20, connecting rod 30, application of force seat 40. The fixing base 20 fixes and stands the knuckle 1 on a laboratory bench (not shown). The force application seat 40 is fixed with the steering knuckle 1 through the connecting rod 30, and the action end of the experiment bench is connected with the force application seat 40 to simulate the action of an automobile balance rod, so that the connecting rod 30 transmits load to the steering knuckle 1 to carry out experiments.

Referring to fig. 3 and 4, the fixing base 20 is composed of a bottom plate 21, a base 22 and a fixing base reinforcing plate 23, the bottom plate is perpendicular to the base, and the fixing base 20 reinforcing plate is clamped from two sides of the bottom plate 21 and synchronously fixed on the base 22 to form the fixing base 20 under the triangular reinforced structure.
