Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing:
[0022] like figure 1 The shown high-power hydraulic torque converter with an integrated guide wheel includes a pump wheel, a turbine 300 , a guide wheel 200 and a front cover 400 . The pump wheel and the front cover 400 are welded together to form an annular cavity, and the guide wheel 200 and the turbine 300 are sequentially embedded in the cavity. The turbine 300 and the guide wheel 200 are connected through the second bearing; the second bearing passes through the middle of the turbine 300 and the guide wheel 200 in turn. The turbine 300 and the front cover 400 are connected through a bearing three 500 ; the three bearings 500 are arranged between the front cover 400 and the turbine 300 .
[0023] like figure 2 As shown, the guide wheel 200 includes a guide wheel body 201 and a guide wheel core block 202 embedded in the middle of the guide wheel body 201 and cast int...

The invention relates to a large-power hydraulic torque converter with an overall type guide wheel. The large-power hydraulic torque converter comprises a pump wheel, a turbine, the guide wheel and afront cover. The pump wheel and the front cover form a cavity in an enclosing manner. The guide wheel and the turbine are sequentially embedded into and installed into the cavity. The pump wheel comprises a pump wheel shell, a tooth sleeve arranged on the outer side of the middle of the pump wheel shell, and a first bearing arranged in the middle cavity of the tooth sleeve in an embedded manner. The guide wheel comprises a guide wheel body and a guide wheel core block which is arranged in the middle of the guide wheel body in an embedded manner and integrally formed with the guide wheel body in a cast manner. According to the converter, the part type is reduced, the product is simplified, the strength of the guide wheel is further enhanced, the bearing is protected, and manufacturing and maintaining are convenient.
Description
technical field [0001] The invention relates to the technical field of hydraulic torque converters, in particular to a high-power hydraulic torque converter with integral guide wheels. Background technique [0002] At present, vehicles using high-power torque converters on the market generally go uphill with heavy loads, and the road conditions are more complicated, requiring frequent torque changes. Therefore, in some fields, in order to meet this transmission characteristic so that it can be better matched with some vehicles or construction machinery models, the guide wheel must remain stationary and need to be directly connected to the external oil pump sleeve and transmission housing fixed, so that the hydraulic torque converter can continuously maintain the torque conversion characteristics during operation. However, the structure of the guide wheel of the hydraulic torque converter on the market is assembled from several parts, the manufacturing process is relatively ...
