Embodiment Construction
[0019] Further explain in detail in conjunction with accompanying drawings;
[0020] As shown in Figures 2 and 4, the limit lifting mechanism 18 adopts a cylinder 27 lifting structure, and the cylinder body and the piston rod of the cylinder are fixedly connected with the attached frame 6 and the measuring platform 10 respectively; the limit lifting mechanism 18 can also adopt a hydraulic pressure Cylinder or screw rod lifting structure.
[0021] As shown in Figures 1 and 7, when used for independent suspension vehicle detection, two groups of measuring rollers 11 are equipped with two groups of identical structures on the outer ends of the end shafts 14 at the opposite inner ends and symmetrically installed with the central functional frame 16 respectively. The force sensing device 15 is composed of: according to the principle of being coaxial with the rotation axis z-z', the force receiving device 28, the pressure sensor 29, and the force receiving device 30 are sequentially...

The automobile steering wheel location detecting instrument belongs to the field of automobile performance detecting apparatus. The specific scheme includes setting independent steering wheel driving mechanism and force driving and measuring mechanism, locating the measuring cylinder in median between the main driving roller and the driven roller, fixing the measuring cylinder on measurement platform with elevating mechanism and limiting and elevating rails, simulating the contact between the steering wheel and ground with the measuring cylinder for dynamic simulating test, transmitting, and detecting and displaying the slip force with the force sensor and corresponding device. The beneficial effects of the present invention include practical detection, reasonable structure, etc. and the present invention is suitable for various kinds of automobile.
Description
technical field [0001] The invention belongs to the field of automobile performance detection devices, and relates to a dynamic detection instrument for steering wheel positioning of automobiles. Background technique [0002] Automobile steering wheel alignment is a general term for kingpin caster, kingpin inclination, steering wheel camber, and steering wheel toe. Steering wheel alignment refers to: kingpin caster angle, kingpin inclination angle, steering wheel camber angle, steering wheel front Beam (mm), for this, each car manufacturer of various models has regulations; kingpin caster and kingpin inclination can ensure that the steering wheel of the car has the ability to automatically return to the center, and can ensure the car's stable straight-line driving; Wheel camber and toe-in are mainly to ensure the safety, stability and economy of driving, especially to eliminate tire sideslip and reduce uneven wear. [0003] In the prior art, the detection of the alignment v...
