Abstract
The invention relates to a hydraulic torque converter. The hydraulic torque converter comprises a pump impeller hub, a guide wheel base and a ball bearing, wherein the pump impeller hub comprises a first end surface and a second end surface which are crossed; an oil inlet channel is arranged between the first end surface and the guide wheel base; an oil outlet channel is arranged between the second end surface and the ball bearing; the oil inlet channel is communicated with one end of the oil outlet channel; the other end of the oil outlet channel is communicated with a bearing inner hole of the ball bearing; a guide end surface is arranged at the part where the first end surface and the second end surface are connected; an included angle of 30 degrees plus (minus) 3 degrees is formed between the guide end surface and the first end surface; and an included angle of 65 degrees plus (minus) 5 degrees is formed between the second end surface and the first end surface. For solving the technical problems of high oil temperature, high oil consumption and poor reliability in the conventional hydraulic torque converter, the hydraulic torque converter disclosed by the invention improves oil liquid circulation and improves product reliability.
Description
Technical field
The present invention relates to a kind of fluid torque converter, mainly be applicable to various forms of fluid torque converters.
Background technique
The high phenomenon of torque-converters oil temperature often appears in existing fluid torque converter.
In conjunction with hydraudynamic drive technology and hot conduction technique, find after the internal structure of the existing part cargo shipment machine torque-converters of analysis, exist serious lacking to limit in the former design, cause product reliability poor, complete-vehicle oil consumption is high.Concrete condition is as follows:
The high phenomenon of the failure of oil temperature in use often appears in conventional fluid torque converter.Conventional face of fluid torque converter hub inboard is wheel stand, as shown in Figure 1 and Figure 2, supports with ball bearing between the two, and the wheel stand inboard is turbine shaft.Be the filler opening of torque-converters oil duct between pump impeller hub and the wheel stand wherein, before the ball bearing of flowing through, oil duct is the right angle type oil duct, and bearing is had direct impact, has greatly hindered the circulation of torque-converters transmission oil.After the circulation of transmission oil was hindered, the inner amount of heat that produces of torque-converters can not in time be delivered to radiator and dispel the heat, and causes torque-converters even temp. of gear-shifting box to raise.
Summary of the invention
Existing fluid torque converter oil temperature is high, oil consumption is high in order to solve, the technical problem of poor reliability, a kind of fluid torque converter of the present invention.
Technical solution of the present invention:
A kind of fluid torque converter, comprise pump impeller hub 1, wheel stand 2 and ball bearing 3, described pump impeller hub 1 comprises two the first crossing end faces 11 and the second end face 12, be provided with oil inlet passage 13 between described the first end face 11 and the wheel stand 2, be provided with oil discharge passage 14 between described the second end face 12 and the ball bearing 3, one end of described oil inlet passage 13 and oil discharge passage 14 communicates, the other end of described oil discharge passage 14 communicates with the brearing bore of ball bearing 3, its special way is: the joint of described the first end face 11 and the second end face 12 is provided with water conservancy diversion end face 111, the angle of described water conservancy diversion end face 111 and 11 one-tenth 30 ° ± 3 ° of the first end faces, described the second end face 12 becomes 65 ° ± 5 ° angles with the first end face.
The angle of above-mentioned water conservancy diversion end face 111 and 11 one-tenth 30 ° of the first end faces, described the second end face 12 becomes 65 ° of angles with the first end face.
The advantage that the present invention has:
1, the present invention has overcome intrinsic deficiency with the pump impeller hub of fluid torque converter from structure, has improved the oil circulation of fluid torque converter, has improved product reliability.
2, face of fluid torque converter hub of the present invention, inner oil channel structure is made an adjustment, keeping on the constant basis of front ball bearing structure, joint at the first end face 11 and the second end face 12 is provided with water conservancy diversion end face 111, the angle of water conservancy diversion end face 111 and 11 one-tenth 30 ° ± 3 ° of the first end faces, the second end face 12 becomes 65 ° ± 5 ° angles with the first end face, eliminated the obstruction of ball bearing to the torque-converters oil inlet passage, guaranteed the unimpeded of torque-converters internal oil passages, reduced the temperature of fluid torque converter, also solved simultaneously because oil temperature is high and caused series of standards part problem of aging, greatly reduced the rate of fault of product, can increase substantially product working life.
