Description

Technical Field

[0001] The invention relates to the technical field of angle detection, and in particular to a device for detecting the rotation angle of a steering drive axle. Background Art

[0002] The steering drive axle is a key component in the automobile transmission system that integrates steering and driving functions. It is located at the front of the vehicle and is mainly composed of the main reducer, differential, half shaft, steering knuckle, wheel hub, etc. When it is working, the engine power is transmitted to the main reducer through the transmission and drive shaft to reduce speed and increase torque, then to the differential, and then transmitted to the wheel by the half shaft to drive the vehicle; at the same time, the driver turns the steering wheel, and the steering force is transmitted to the steering knuckle through the steering rod to turn the wheel. It is widely used in front-wheel drive cars, light buses and some off-road vehicles, etc., and has the characteristics of flexible steering and efficient driving.

[0003] A patent application with application number CN201910146057.5 discloses a rotation angle detection device for a rotating shaft, including a laser emitting device, a bonding device and a processing and display device. The laser emitting device generates a laser beam and adjusts it to circularly polarized light. The bonding device includes a first prism and a second prism symmetrically installed. The mirror surface of the first prism is perpendicular to the mirror surface of the second prism, and one side of the first prism contacts one side of the second prism. The bonding device is fixed on the object to be measured and the connection line between the first prism and the second prism is on the same straight line as the rotation axis of the object to be measured. Circularly polarized light enters the bonding device, and after being reflected by the first prism and the second prism, elliptically polarized light is output and enters the processing and display device. The processing and display device adjusts the elliptically polarized light to linearly polarized light and filters it, and measures the intensity difference between the s light and the p light based on the filtered linearly polarized light, and determines the rotation angle of the object to be measured based on the intensity difference.

[0004] After the production of the steering drive axle is completed, the produced products will be tested to ensure that the deflection angle of the steering drive axle will not have too large an error. However, the detection method of existing equipment mostly uses the deflection angle of the steering drive axle rotation point to detect, which is different from the actual rotation angle of the tire in actual use of the equipment. This leads to a large deviation between the test results of the equipment and actual use, which reduces the detection effect of the equipment. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a steering drive axle rotation angle detection device to solve the problems raised in the above background technology.

When the output end of the steering drive axle is embedded in the embedding hole, the elastic pressure plate fits tightly on the bolt extended from the steering drive axle. In this way, when the equipment detects the deflection angle of the steering drive axle, the deflection reaction lag caused by insufficient friction can be effectively avoided, thereby ensuring the accuracy of the equipment's angle detection and preventing large errors.

[0018] 3. The present invention sets a central component to apply additional force to the U-shaped plate when it deflects left and right, thereby simulating the influence of the friction between the tire and the ground on the steering angle when the steering drive axle is actually used. This simulation method can highly restore the real state of the steering drive axle in actual application, thereby ensuring the accuracy of equipment detection.

[0019] 4. The present invention sets a locking mechanism to determine the deflection state of the U-shaped plate 1 by constraining the movable block when the equipment is not testing.
