Abstract
The utility model belongs to a hydraulic element and in particular relates to a composite oil supply pump for a torque converter. The composite oil supply pump comprises a pump cover (5), a pump body (4), a driving gear (7), a driven gear (1), a driven shaft (3), a sealing framework (6) and a needle roller bearing (2), wherein a main pressure valve assembly (10), a main oil way outlet (5-2), a torque converter pressure valve assembly (9) and a torque converter oil inlet (5-4) are arranged on the pump cover (5); and a duplex metal composite bearing (8) is inlaid in an inner hole of the driving gear (7) and is arranged on a guide wheel shaft (5-1) which is integrally cast with the pump cover (5). According to the composite oil supply pump for the torque converter, the oil supply, the main pressure valve assembly and the torque converter pressure valve assembly are integrated, an integrated and multifunctional hydraulic power element is formed, and the composite oil supply pump is high in integration degree, compact in structure and zero in leakage.
Description
Technical field
The utility model belongs to hydraulic element, the compound oil feed pump of particularly a kind of torque-converters.
Background technique
Original bending moment oil feed pump is designed to the structural type of pump valve split, and oil circuit is arranged loaded down with trivial details, causes leakage point and fault point many, and has the shortcoming that energy loss is big, host work efficient is low, maintenance cost is high.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, and nothing is leaked, fault is few, the compound oil feed pump of the torque-converters of high working efficiency.
The technological scheme that the utility model technical solution problem adopts is: the compound oil feed pump of torque-converters comprises pump cover, the pump housing, driving gear, driven gear, driven shaft, sealing skeleton, needle bearing; Be characterized in that main pressure valve assembly, working connection outlet, torque converter pressure valve assembly and torque-converters filler opening all are arranged on the pump cover; Driving gear endoporus insert bimetal composite bearing, and be installed in pump cover guide wheel shaft cast in block on.
The beneficial effect of the utility model is: the compound oil feed pump of torque-converters integrates fuel feeding, main pressure valve assembly, torque converter pressure valve assembly, has formed integrated, multifunction hydraulic dynamical element, and integrated degree is high, and compact structure does not have and leaks.Overcome in the conventional construction because pump valve separates, element disperses, cause oil circuit to arrange loaded down with trivial details, leakage point and the fault point is many, energy loss greatly, host work efficient is low, maintenance cost is high shortcoming; Pressure surge in the time of can reducing torque-converters work and hydraulic systems vibration; Practice thrift principal pressure valve body, the torque converter pressure valve body of original structure, cancel external oil circuit, make torque-converters oil circuit layout more reasonable; Profile is more attractive in appearance, and has reduced manufacturing and assembly cost.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the compound oil feed pump structural drawing of torque-converters.
Fig. 2 is that figure cuts open in internal structure and office behind the dismounting pump housing of Fig. 1.
Among the figure, the 1-driven gear; The 2-needle bearing; The 3-driven shaft; The 4-pump housing; The 5-pump cover; The 5-1-guide wheel shaft; The outlet of 5-2-working connection; 5-3-oil feed pump filler opening; 5-4-torque-converters filler opening; 6-seals skeleton; The 7-driving gear; 8-bimetal composite bearing; 9-torque converter pressure valve assembly; 10-pressure valve assembly.
Embodiment
Embodiment; With reference to accompanying drawing 1,2; Connect with screw between the pump cover 5 of the compound oil feed pump of torque-converters and the pump housing 4; Guide wheel shaft 5-1 and pump cover 5 cast solids, main pressure valve assembly 10, working connection outlet 5-2, torque converter pressure valve assembly 9, torque-converters filler opening 5-4 and oil feed pump filler opening 5-3 all are arranged on the pump cover 5.Driving gear 7 endoporus insert bimetal composite bearings 8 are sleeved on the guide wheel shaft 5-1; Driving gear 7 is connected by meshing transmission with driven gear 1; Driven gear 1 is sleeved on the driven shaft 3; Driven shaft 3 is contained on the pump housing 4, between driven gear 1 and the driven shaft 3 needle bearing 2 is housed, and sealing skeleton 6 is housed between the pump housing 4 and the guide wheel shaft 5-1.
The compound oil feed pump working principle of torque-converters is: the pressure of main pressure valve assembly 10 control working connection outlet 5-2; Setting value guarantees the needed hydraulic working oil pressure of torque-converters control system; 9 controls of torque converter pressure valve assembly get into the hydraulic fluid pressure of torque-converters, and setting value guarantees inner required flow of lubrication of torque-converters and heat exchanger flow.
