Automobile wheel pulse collecting device and automobile

Abstract

The invention provides an automobile wheel pulse collecting device and an automobile. One end of an encoder assembly is fixedly connected with an automobile wheel so that an automobile running parameter can be collected, and the other end of the encoder assembly is connected to an automobile body connection piece through a connection assembly. The connection assembly comprises a connection rod, a first universal ball joint and a second universal ball joint. The first universal ball joint is arranged at the first end of the connection rod. The second universal ball joint is arranged at the second end of the connection rod. The first universal ball joint is connected with the encoder assembly. The second universal ball joint is connected with the automobile body connection piece. The two ends of the connection rod are provided with the first universal ball joint and the second universal ball joint correspondingly, so that the connection rod is capable of rotating on an X axis, a Y axis and a Z axis, and when the automobile is driven on a special road segment, the situation that the automobile wheel pulse collecting device is deformed due to the fact that force is applied in a certain direction can be avoided; and accordingly, the stability of the automobile wheel pulse collecting device is improved, and normal working of the automobile wheel pulse collecting device is ensured.

Description

technical field [0001] The invention relates to mechanical technology, in particular to an automobile wheel pulse acquisition device and an automobile. Background technique [0002] Statistics of vehicle driving parameters, such as statistics of vehicle driving distance and vehicle speed, have important reference value for vehicle life estimation, safety performance estimation and maintenance time determination. [0003] The vehicle wheel pulse acquisition device includes a clamp, a connecting rod and an encoder assembly. The encoder assembly is fixedly connected to the vehicle wheel to count the driving parameters of the vehicle. The clamp is mounted on the body, and the clamp and the encoder assembly are connected through the connecting rod. The connecting rod comprising a first part and a second part, wherein the first end of the first part is rotatably connected to the body clamp, the second end of the first part is rotatably connected to the first end of the second part...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned automobile wheel pulse acquisition device cannot meet the requirements of long-term continuous operation, and the stability of the automobile wheel pulse acquisition device is not strong. When the vehicle is running on a special road section, the Z-axis accepts the deformation of the entire automobile wheel pulse acquisition device. Serious cases may fall off on site, affecting the normal work of the car wheel pulse device
