Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile manufacturing, and specifically to a combined measuring device for assembling the steering angle of an automobile steering drive front axle assembly. BACKGROUND

[0002] When designing a complete vehicle, the steering angle of the steering drive front axle assembly is required to be between 34-41 degrees. If the steering angle is too small, the steering is not in place, and the vehicle needs to be turned frequently while turning, especially when turning sharply, the vehicle cannot turn, and it needs to be reversed several times to finally turn, and sometimes safety accidents such as rollover occur. If the steering angle is too large, when the steering reaches the maximum steering angle, some parts of the wheel end assembly collide with each other, causing damage to the parts. Therefore, when assembling the axle, the steering angle needs to be adjusted according to the technical requirements, and after adjustment, the value of the steering angle needs to be kept fixed. If the steering angle is not adjusted accurately, the error is too large, which will bring serious safety hazards to the vehicle.

[0003] At present, the most common way to solve the above problems is to use expensive laser equipment or self-made measuring tools with complex structure.
