Embodiment Construction
[0024] CJC elastic side bearing is the key component of C80E heavy-duty truck. After the completion of the vehicle, the vertical compression of the CJC elastic side bearing is an important parameter affecting the running stability of the vehicle, and the assembly quality of the CJC elastic side bearing is a key factor affecting the vertical compression of the side bearing.
[0025] Based on the above analysis, see figure 1 and figure 2 , The embodiment of the present invention provides a CJC-type elastic side support side panel fixing device 2 , including: a beam 22 , a first longitudinal beam 21 , a second longitudinal beam 23 and a handle 24 . The length of the cross beam 22 is slightly smaller than the distance between the left and right two CJC type elastic side bearing plates placed in the CJC type elastic side bearing seat. One end of the first longitudinal beam 21 is vertically fixed on one end of the cross beam 22, and the first The longitudinal beam 21 is used to f...

The invention relates to the technical field of rail transit, in particular to a CJC type elastic side bearing side plate fixing device and a CJC type elastic side bearing press fitting method. The CJC type elastic side bearing side plate fixing device comprises a cross beam, a first longitudinal beam and a second longitudinal beam, wherein one end of the first longitudinal beam is fixedly arranged at one end of the cross beam; one end of the second longitudinal beam is fixedly arranged at the other end of the cross beam. According to the CJC type elastic side bearing press fitting method, a CJC type elastic side bearing side plate is temporarily fixed by using the CJC type elastic side bearing side plate fixing device, and press fitting of an entire CJC type elastic side bearing is realized. According to the CJC type elastic side bearing side plate fixing device and the CJC type elastic side bearing press fitting method, the entire press fitting process of the CJC type elastic side bearing is simple and quick. Meanwhile, the CJC elastic side bearing is accurate in positioning, and the press fitting quality of the CJC type elastic side bearing is guaranteed, so that a railway vehicle can operate stably.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a CJC type elastic side bearing side plate fixing device and a CJC type elastic side bearing pressure mounting method. Background technique [0002] CJC elastic side bearing is the key component of C80E heavy-duty truck. After the completion of the vehicle, the vertical compression of the CJC elastic side bearing is an important parameter affecting the running stability of the vehicle, and the assembly quality of the CJC elastic side bearing is a key factor affecting the vertical compression of the side bearing. The existing railway freight car elastic side bearing pressure installation technology is mainly applicable to the JC and BD type elastic side bearing pressure installation technology, and the CJC elastic side bearing is quite different from the JC and BD type side bearing structures, and the CJC elastic side bearing The left and right side plates are separated from...
