Embodiment Construction

[0061] Such as Figure 1 to Figure 5 As shown, this example is mainly composed of a cover wheel assembly 1, a turbine assembly 2, a guide wheel assembly 3, and a pump wheel assembly 4; wherein: the power input end is composed of the cover wheel 1 and the pump wheel 4, and the power output end is passed by the turbine 2 Turbine shaft composition. The specific structural parameters of each working wheel are as follows:

[0062] The diameter of the circulating circle of the hydraulic torque converter φD is 340±4mm;

[0063] The average inlet and outlet radius of the middle streamline of each working wheel:

[0064] The average inlet radius ρ of the middle streamline of the impeller body B1 =92.7±2mm;

[0065] The average radius ρ of the outlet of the middle streamline of the impeller body B1 =158.5±2mm;

[0066] The average inlet radius ρ of the middle streamline of the turbine body T1 =158.5±2mm;

[0067] The average radius ρ of the outlet of the middle streamline of the...

Abstract

The invention relates to a hydraulic torque converter used for a low-rotating-speed road roller. The hydraulic torque converter comprises a turbine body, a pump wheel body and a guide wheel body. Through reasonable design of all parameters of the turbine body, the pump wheel body and the guide wheel body, the value of complete machine zero-speed pump wheel nominal torque Mbg0 per thousand revolutions is large, the highest efficiency is high, the high-efficiency area is wide, and therefore it is ensured that good fuel economy and heat balance can be achieved for the whole roller.

Description

technical field [0001] The invention relates to a hydraulic torque converter, which is suitable for road rollers with low-speed engines of 26 tons and above 30 tons. Background technique [0002] The existing hydraulic torque converter includes a turbine, a guide wheel and a pump wheel, and its zero-speed pump wheel thousand revolution nominal torque M bg0 The value is relatively small, and the torque ratio K 0 The value is relatively large, and the maximum efficiency value is relatively low, which is suitable for the loader matching the engine with high speed. The working condition of the road roller is relatively simple, and the engine requires full power to match the hydraulic torque converter, which is used in the traction condition of the whole vehicle. The road roller equipped with a low-speed engine puts forward higher performance requirements for the hydraulic torque converter. Nominal moment M bg0 The value should be as large as possible, the highest efficiency s...
