Embodiment Construction
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. like Figure 1-4 As shown, a rapid speed measuring device for an encoder for a tractor mainly includes: an encoder shield 1, an encoder speed measuring assembly 2, a bearing seat 3, and a suction cup assembly 4. The encoder shield 1 is coaxial with the bearing seat 3. The encoder shield 1 is fixed on the bearing seat 3 by six inner hexagonal screws 8 evenly distributed around the circumference, and is installed outside the encoder speed measuring assembly 2. The encoder 13 rotates and rotates to protect the encoder 13 from damage. The encoder speed measuring assembly 2 is connected with the bearing seat 3 and the suction cup assembly 4 in sequence. The encoder speed measuring assembly 2 mainly plays the role of speed measuring in the test, and the suction cup assembly 4 mainly acts as a fixing device in the test. One end of the circular hole of the sucti...

The invention discloses a rapid encoder speed measurement device and method for tractors. The device comprises an encoder protection cover, an encoder speed measurement assembly, a bearing pedestal and a sucking disk assembly, wherein the encoder protection cover is coaxial with the bearing pedestal, fixed on the bearing pedestal through an inner hexagonal screw and mounted at the outer part of the encoder speed measurement assembly; the encoder speed measurement assembly is connected with the bearing pedestal and the sucking disk assembly in sequence; the end, with a circular hole, of the sucking disk assembly is fixed on the encoder speed measurement assembly through a sucking disk locking plate; and the other end of the sucking disk assembly is sleeved in an axle end of a measured tractor wheel and adsorbed on the measured tractor wheel through four magnets. Compared with other speed measurement devices and methods, the speed measurement device and method provided by the invention have the advantages that the data obtained by an encoder is more correct and the accuracy of test data is improved. Therefore, the speed measurement device has the characteristics of being compact in structure, convenient to dismount, low in hardware cost and high in test precision, and is particularly suitable for outdoor test conditions or complete tractors or other vehicles.
Description
technical field [0001] The invention belongs to the field of complete tractor testing equipment, and relates to a speed measuring device for tractors, in particular to a fast speed measuring device and a speed measuring method for encoders used for tractors. Background technique [0002] As we all know, the speed of the tractor is a key test data during the whole tractor test process. Therefore, there are many test occasions that need to obtain the wheel speed of the tractor. Regarding vehicle speed measurement, the commonly used methods currently mainly include radar speed measurement or image acquisition and processing speed measurement, but both of them have higher test costs and higher requirements for the test environment. The test data is greatly affected by the environment and are not suitable for tractors with harsh operating conditions. Speedometer. At present, there are many ways to measure the speed of a tractor. The most common way is to stick a piece of reflec...
