Embodiment Construction
[0070] The present invention is described in detail below in conjunction with accompanying drawing:
[0071] refer to Figure 1-4 , the described Hall effect type automobile wheel speed detection device with a buffer is mainly composed of an L-shaped connecting rod A, a code disc mechanism assembly B, a wheel speed detection mechanism assembly C, a buffer D and an upper fixing mechanism assembly Into E composition. The lower part of the Hall effect type automobile wheel speed detection device with a buffer is fixedly installed on the wheel hub of the tested vehicle I through the adapter assembly III and the nut to realize the code disc 5 Synchronous operation with the wheels; the strong magnet 13 in the upper fixing mechanism assembly E is adsorbed on the car body to realize the upper fixing of the wheel speed detection device.
[0072] refer to Figure 1-3 , the adapter assembly III is composed of three sets of adapter nuts a with the same structure, the adapter nut a is a...

The invention discloses a Hall effect type automobile wheel speed detecting device with a buffer. The Hall effect type automobile wheel speed detecting device mainly comprises an L-shaped connecting rod, a coded disc mechanism assembly, a wheel speed detecting mechanism assembly, the buffer and an upper fixing mechanism assembly; the coded disc mechanism assembly on the lower portion of the wheel speed detecting device is fixedly mounted on a hub of a detected automobile I by a connecting device III, so that a coded disc and a wheel rotate synchronously; and a strong magnet in the upper fixing mechanism assembly is attracted onto an automobile body, so that the upper portion of the wheel speed detecting device is fixed. A coded disc structure with mounting holes radially arranged at unequal angles can be quickly and conveniently mounted on the hub of the automobile and is applicable to different types of automobiles with different quantities of nuts, and pulse signal testing holes which are uniformly distributed are arranged on the edge of the coded disc, so that the wheel speed is directly measured; and a vertical buffering mechanism in the device eliminates influences of vertical vibration to the wheel speed detecting device when the automobile runs, and the Hall effect type automobile wheel speed detecting device is low in cost, convenient to install and high in test precision and universality.
Description
technical field [0001] The invention relates to a detection system applied in the field of automobiles, in particular to a Hall effect type automobile wheel speed detection device with a buffer. Background technique [0002] Wheel speed is one of the important test parameters when the vehicle is tested on the road, which is of great significance to the evaluation of vehicle performance. At present, the independent wheel speed test device has disadvantages such as poor versatility and large external influence during the road test, and foreign equipment is expensive, which restricts the test of wheel speed parameters to a certain extent. [0003] After searching, (1) patent publication number: CN101339199A; invention name: electromagnetic wheel speed sensor and its installation method; publication date: January 7, 2009; application date: August 1, 2008. This patent proposes an electromagnetic vehicle wheel speed sensor. The ring gear is fixed on the wheel hub and rotates with...
