Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary automobile steering adjustment tooling structure, in particular to a maximum steering angle adjustment device for automobile front wheels. Background Art
[0002] The maximum steering angle of the front wheels refers to the deviation angle when the front wheels turn left or right to the extreme position. The existing method of adjusting the maximum inner and outer steering angles of the front wheels of a car is: screw the left and right limit bolts of the front wheels directly into the limit holes of the front axle. Employees use their own experience to observe the exposed length of the bolts and the center position of the two front wheels to judge whether the deviation angle of the front wheels when turning left or right to the extreme position in the subsequent process steps meets the angle requirements of the previous process steps; a more precise angle measurement method is to jack up the front axle so that the front wheels are in a straight driving position, and put a piece of wood and white paper under the tire, then put the wooden ruler close to the outer edge of the tire, and use a pen to draw a straight line on the paper parallel to the front wheel, then turn the steering wheel to the left or right to the bottom, and then use the same method to draw a straight line intersecting with the first straight line. Finally, use a protractor to roughly measure the steering angle of the front wheels.
[0003] The above two methods of adjusting the offset angle of the maximum inner and outer steering angle of the front wheels of the car not only have large errors, but also are cumbersome to operate. It is not possible to directly observe whether the front wheels are in the center position during the steering angle adjustment process, which results in a large difference in the number of left and right turns of the steering wheel during the assembly process, which affects the stability, safety and handling of the vehicle, and also reduces the service life of the tires.

[0022] See also Figure 1 to Figure 2 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance.

[0023] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.
[0024] See also Figure 1The utility model provides a device for adjusting the maximum steering angle of the front wheels of a vehicle, which is used to observe whether the two front wheels of the vehicle are in the center position after the front wheels of the vehicle are turned to the extreme position, and comprises a steering gear locking component 1 and a front wheel locking component 2; after the front wheels of the vehicle are turned to the extreme position, the operator can use the steering gear locking component 1 to lock the output shaft of the steering gear 3, and then lock the front wheel locking component 2 at the limiting hole of the front axle 4, and an orientation observation piece 21 is installed on the front wheel locking component 2. In subsequent work, by observing the orientation observation piece 21 installed on the front wheel locking component 2, it is possible to accurately judge whether the front wheels are still in the center position, that is, to judge whether the offset angle of the front wheels when turning left or right to the extreme position in the subsequent process steps meets the angle requirement of the front wheels turning left or right to the extreme position in the previous process steps.
[0025] This avoids the problem in the background technology that the operator uses his own experience to observe the exposed length of the bolts and the center position of the two front wheels to judge whether the offset angle of the front wheel when turning to the left or right to the extreme position in the subsequent process step meets the angle requirement of the previous process step, or uses a protractor to roughly measure the steering angle of the front wheel, which leads to large errors, resulting in a large difference in the number of left and right turns of the steering wheel, affecting the stability, safety and handling of the vehicle; and also improves the service life of the tires.
[0026] In another embodiment, see Figure 2 The front wheel locking component 2 includes a clamping pair of arms 22 and a limiting bolt 23, and the orientation observation piece 21 is installed on the clamping pair of arms 22; the clamping pair of arms 22 clamps the two ends of the limiting hole of the front axle 4, and the limiting bolt 23 is screwed into the limiting hole of the front axle 4 from one side of the clamping pair of arms 22. The operator can quickly put the clamping pair of arms 22 on the two ends of the limiting hole of the front axle 4, and then screw in the limiting bolt 23, just like screwing in the assembly bolt normally, which is convenient for the operator's operation and ensures the operator's operating proficiency.
[0027] In another embodiment, see Figure 2 The orientation observation piece 21 is "T"-shaped, and the bottom end of the "T"-shaped orientation observation piece 21 is fixedly mounted on the top end of the clamping pair of arms 22, which can be welded or plugged in. The design of the bottom end of the "T"-shaped orientation observation piece 21 being fixedly mounted on the top end of the clamping pair of arms 22 not only obtains a simple-structured orientation observation piece 21, but also the upper horizontal arm of the "T"-shaped orientation observation piece 21 is also convenient for observation by operators.
[0028] In another embodiment, see Figure 2The orientation observation piece 21 is in a "cross" shape, and the bottom end of the "cross" shaped orientation observation piece 21 is fixedly mounted on the top end of the clamping pair of arms 22. This embodiment provides a structural form of the orientation observation piece 21 other than the "T" shape, and technicians can choose according to actual needs.
[0029] In another embodiment, see Figure 2 The outer end of the limiting bolt 23 is provided with a twist handle 24, so that the operator can quickly lock the front wheel locking component 2 at the limiting hole of the front axle 4, thereby improving the comfort of use of the device.
[0030] In another embodiment, see Figure 2 The steering gear locking component 1 includes a positioning plate 11 and a limiting shaft 12, on which a spline groove is provided, and the positioning plate 11 is mounted on the output shaft of the steering gear 3; the device is designed with a spline groove on the limiting shaft 12, and can use the spline structure on the common steering gear 3 to quickly insert the limiting shaft 12 from the side wall of the positioning plate 11, and use the spline groove on the limiting shaft 12 and the spline of the output shaft of the steering gear 3 to achieve the function of the steering gear locking component 1 locking the output shaft of the steering gear 3. Of course, if there is a spline groove on the output shaft of the steering gear 3, then the limiting shaft 12 is provided with a spline, which will not be repeated here.
[0031] In other embodiments, Figure 2 As shown, the positioning plate 11 includes a chassis 111 and a limiting plate 112. The bottom surface of the chassis 111 matches the end surface of the steering gear 3. The limiting plate 112 is fixedly mounted on the chassis 111. The limiting shaft 12 is inserted from the side wall of the limiting plate 112. The overall stability of the positioning plate 11 is enhanced through the design of the chassis 111 and the limiting plate 112.
[0032] In summary, the utility model is designed with the steering gear locking component 1 and the front wheel locking component 2. After the front wheel of the car is turned to the extreme position, the operator can use the steering gear locking component 1 to lock the output shaft of the steering gear 3, and then lock the front wheel locking component 2 at the limit hole of the front axle 4. In the subsequent work, by observing the azimuth observation component 21 installed on the front wheel locking component 2, it can be accurately judged whether the front wheel is still in the center position, that is, whether the offset angle when the front wheel turns left or right to the extreme position in the subsequent process steps meets the angle requirement of the front wheel turning left or right to the extreme position in the previous process steps. The utility model also has a design that the azimuth observation component 21 is "T"-shaped, and the bottom end of the "T"-shaped azimuth observation component 21 is fixedly installed on the top of the clamping arm 22, not only a simple azimuth observation component 21 is obtained, but also the upper cross arm of the "T"-shaped azimuth observation component 21 is also conducive to the observation of the operator.
