Problems solved by technology

If the two ends of the axle are double wheels, the wheelbase is the distance between the two center planes of the double wheels, and the distance between the skateboards on both sides of the existing sideslip detection platform cannot be adjusted according to different wheelbases, causing the car to move when entering the vehicle. It is easy to find that the side skateboards are not located on the driving path of the front wheels when arriving at the testing platform. At this time, it is necessary to manually adjust the orientation of the car or the position between the skateboards on both sides, which is difficult to adjust and takes a long time, which affects the accuracy of the test results. At the same time, the existing side skateboards cannot be accurately positioned, so that the front wheels of the car cannot run at the center of the side skateboards, and it is easy for the front wheels of the car to run on both sides of the side skateboards. When the force is applied on one side, a certain amount of side slip will be generated, resulting in inaccurate sideslip distance, which will cause a large difference between the measured side slip value and the actual side slip value; because the car enters from different directions, the car body will be different. The angle of inclination, the existing technology is to manually drive the vehicle to adjust it, and then drive it into the side slip detection platform for detection. Manual alignment requires multiple adjustments, and the space in the detection area is limited, resulting in the vehicle not being able to completely adjust. Positive, which in turn affects the detection of the side slip of the steering wheel of the car, resulting in a large error in the detected data

Embodiment 1

[0060] Embodiment one: if figure 1 and Figure 4 Shown, drive mechanism 24 comprises screw mandrel 30, electromagnet 31, magnet 32, push rod 44, screw mandrel seat 45, motor 46 and mounting plate 47, and mounting plate 47 is fixed on the frame 1, and screw mandrel seat 45 is fixed on On the top of the mounting plate 47, the screw mandrel 30 is rotatably connected with the screw mandrel seat 45 through the bearing, the screw mandrel 30 is vertically arranged with the left side slide plate 21, the push rod 44 is threadedly connected with the screw mandrel 30, and the push rod 44 is "L" type, Push rod 44 is arranged in parallel with screw mandrel 30, and the bottom of push rod 44 contacts with mounting plate 47, and the end of push rod 44 away from screw mandrel seat 45 is fixed with electromagnet 31, and motor 46 is fixed on the mounting plate 47, and the motor 46 The output shaft is connected to one end of the screw mandrel 30, and the side of the left slide plate 21 and the r...

Embodiment 2

[0070] The working process of the driving mechanism 24 in the second embodiment is as follows: start the motor 46, and the motor 46 drives the screw mandrel 30 to rotate. Since the push rod 44 is in contact with the mounting plate 47, the rotation degree of freedom of the push rod 44 is limited, so that the screw mandrel 30 and push rod 44 form a screw nut pair, so that push rod 44 moves along the length direction of screw rod 30; forward rotation motor 46 drives push rod 44 to move forward through screw rod 30, and drives conical connecting block 49 to approach wedge-shaped Block 48 moves, and when the tapered surface of conical connection block 49 contacts with wedge-shaped surface one 52, due to the guiding action of wedge-shaped surface one 52, under the effect of force applied continuously by conical connection block 49, wedge-shaped block 48 is made close to magnet 32 Setting, the connecting spring 57 is compressed, when the tapered connecting block 49 passes through the ...

Abstract

The invention discloses an automobile sideslip detection table with an automatic positioning function and a detection method. The detection table comprises a rack, a sideslip detection assembly, a sensing assembly and an automobile straightening assembly, the automobile straightening assembly, the sensing assembly and the sideslip detection assembly are sequentially arranged on the rack from frontto back, and the sideslip detection assembly is connected with the automobile straightening assembly through a positioning sliding mechanism. An automobile drives onto the rack, when the front wheelsof the automobile are sensed by a photoelectric switch, the automobile stops, then the automobile is straightened through the automobile straightening assembly so that the front and rear wheels of the automobile drive in perpendicular to a left sliding plate and a right sliding plate, meanwhile, the positioning sliding mechanism drives the sideslip detection assembly to move for preliminary positioning, then the sideslip detection assembly is accurately positioned, and after positioning is completed, the front wheels of the automobile drive into the sideslip detection assembly to complete detection of sideslip of the front wheels of the automobile, so that sideslip detection of the automobile is more accurate.

Description

technical field [0001] The invention relates to the field of vehicle side-slip detection, in particular to a detection method of a vehicle side-slip detection platform with an automatic positioning function. Background technique [0002] The detection of the side slip of the steering wheel of the automobile is one of the important contents to ensure the safe operation of the automobile. The sideslip mentioned in this manual refers to the sideslip of the steering wheel of the car, not the overall side slip of the car when braking. Front wheel side slip refers to the mismatch between the toe and camber of the front wheels (the lateral force generated by the camber and the lateral force generated by the toe are unbalanced), causing the car to deviate left or right when driving in a straight line Phenomenon. It reflects the stability of the car in a straight line. At this time, while the steering wheel rolls forward, it will also produce a phenomenon of lateral slip, which is...
