Embodiment 1
[0037] A shear-compression composite elastic wheel for low-floor trams, such as figure 1 and figure 2As shown, it includes the wheel core 1a, the tire 2a, and the ground connection wire 5a installed on the wheel core 1a and the tire 2a. A U-shaped rubber layer 3a is installed between the wheel core 1a and the tire 2a. The U-shaped rubber The layer 3a is a continuous ring along the circumferential direction of the wheel, and the outer surface of the side wall of the wheel core 1a is provided with a mounting groove along the circumferential direction, and a pressure ring 4a is installed in the mounting groove, and the end surface of the pressure ring 4a is provided with threaded holes. The pressure ring 4a is installed on the wheel core 2 through the threaded hole and the U-shaped rubber layer 3a through the first bolt 42a; 2-4 ejection threaded holes 41a are set on the pressure ring 4a, and the ejection threaded holes 41a are used for assembling and disassembling the ejector. ...
Embodiment 2
[0041] The preparation process of the wheel core and tire is the same, and the specific preparation process is as follows:
[0042] In the first step, the molten paraffin is injected into the mold coated with a release agent on the inner surface through a wax press machine, and then cooled and demolded to obtain a wax film. After the paraffin is injected, a wax film installation shaft is placed in the mold. Fixed on the installation shaft after paraffin demoulding;
[0043] In the second step, the wax film is installed on the continuous casting and demoulding production line through the installation shaft, and the mold shell is prepared by rotating on the production line. The four corners of the continuous demoulding production line are respectively equipped with an alkali cleaning cylinder, a self-transfer coating bearing Condensed gypsum slurry holding cylinder and hot water cooking tank, and between the lye cleaning cylinder and the self-transfer coating cylinder, between t...
Embodiment 3
[0051] Such as image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the continuous casting demoulding production line includes a carrier frame 1, four transmission gears 2 are installed on the top four corners of the carrier frame 1, and the four transmission gears 2 are connected by a transmission chain 3, and the outer sides of the transmission chain 3 are installed at equal angles. Four fixed bars 31, hydraulic cylinder 4 is installed on the bottom surface of fixed bar 31, the bottom of hydraulic cylinder 4 is equipped with elastic rotating seat 5, and the wax film installation shaft is installed on the bottom of elastic rotating seat 5;
[0052] The four corners of the surface of the bottom plate 11 of the carrier frame 1 are respectively placed with an lye cleaning cylinder, a self-transfer paint carrying cylinder, an adhesive gypsum slurry carrying cylinder and a hot water cooking tank, and are located between the lye cleaning cylinder and...
