Abstract
The utility model relates to a torque converter's fender ring, keep off the die casting that the ring is the ring structure, keep off the outer lane of ring and be the flange form, the outer lane is equipped with the L shape location breach that three even circumference distributes, and the hole that keeps off the ring is two sections step holes, and the diameter in first step hole is greater than second step hole diameter, first step hole side is equipped with the U-shaped oil groove that three even circumference distributes, the oil groove is the non-processing groove, and the biggest appearance of oil groove is greater than the external diameter in first step hole, and the degree of depth of oil groove is greater than first step hole height, and the bottom surface of oil groove is arranged in second step hole lateral wall. The utility model has the advantages that: the baffle ring with the structure is adopted, wherein the U-shaped oil groove serving as an oil way is a die casting part, and replaces a machining oil hole in an original structure, so that a subsequent machining process is omitted, the machining cost is saved, and the production efficiency is improved.
Description
Technical Field
The utility model belongs to the technical field of the car, in particular to torque converter's fender ring.
Background
The baffle ring is a part for fixing the one-way clutch in the hydraulic torque converter, the baffle ring and the one-way clutch are arranged between an inner ring and an outer ring on a turbine shaft, the baffle ring is arranged on two sides of the one-way clutch, the traditional baffle ring structure is that 3 oil holes which are uniformly distributed on the periphery are drilled on the baffle ring, when the torque converter supplies oil, hydraulic transmission oil enters the one-way clutch from one side of a pump wheel shell through a rear baffle ring oil hole and then flows out from a front baffle ring oil hole, so that the one-way clutch is kept in a lubricating state all the time during working. The existing baffle ring needs to be drilled through a machining center after turning, if the structure of the baffle ring is improved, an oil way is taken out when the baffle ring is subjected to die casting, so that the subsequent machining procedure can be omitted, the cost is saved, and the production efficiency is improved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's is not enough, reduces the processing cost, improves production efficiency, provides a torque converter's fender ring.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a baffle ring of a hydraulic torque converter is a die casting with a circular ring structure, the outer ring of the baffle ring is in a flange shape, and the outer ring is provided with three L-shaped positioning notches which are uniformly distributed; the inner hole of the baffle ring is two sections of step holes, and the diameter of the first step hole is larger than that of the second step hole; the side surface of the first step hole is provided with three U-shaped oil grooves which are evenly distributed in the circumferential direction, the oil grooves are non-machined grooves, the maximum appearance of each oil groove is larger than the outer diameter of the corresponding first step hole, the depth of each oil groove is larger than the height of the corresponding first step hole, and the bottom surface of each oil groove is located in the side wall of the corresponding second step hole.
The utility model has the advantages that: the baffle ring with the structure is adopted, wherein the U-shaped oil groove serving as an oil way is a die casting part, and replaces a machining oil hole in an original structure, so that a subsequent machining process is omitted, the machining cost is saved, and the production efficiency is improved.

In the figure: 1-outer ring, 2-positioning gap, 3-first step hole, 4-second step hole, 5-oil groove, 6-turbine shaft, 7-rear retaining ring, 8-inner ring, 9-one-way clutch, 10-outer ring, 11-front retaining ring and 12-oil hole.
Detailed Description
The technical solution of the present invention is further described in detail below with reference to the following embodiments and the accompanying drawings:
referring to fig. 3 and 4, for the original retainer ring structure, 3 oil holes 12 are circumferentially and uniformly distributed at the flange edge of the retainer ring, and the oil holes 12 are processing holes.
Referring to fig. 1 and 2, the baffle ring of the hydraulic torque converter is a die casting with a circular ring structure, an outer ring 1 of the baffle ring is in a flange shape, the outer ring 1 is provided with three L-shaped positioning notches 2 which are uniformly distributed circumferentially, an inner hole of the baffle ring is a two-section step hole, and the diameter of a first step hole 3 is larger than that of a second step hole 4; the side of the first step hole 3 is provided with three U-shaped oil grooves 5 which are evenly distributed circumferentially, the oil grooves 5 are non-machined grooves, the maximum appearance of the oil grooves 5 is larger than the diameter of the first step hole 3, the depth of the oil grooves 5 is larger than the height of the first step hole 3, and the bottom surface of the oil grooves 5 is positioned in the side wall of the second step hole 4.
The working principle is as follows:
as shown in fig. 5, a front retainer 11, a rear retainer 7, and a one-way clutch 9 are provided between an inner ring 8 and an outer ring 10 on the turbine shaft 6, the front retainer 11 is installed on the left side of the one-way clutch 9, and the rear retainer 7 is installed on the right side of the one-way clutch 9. When the hydraulic torque converter supplies oil, hydraulic transmission oil enters the one-way clutch 9 from one side of the pump wheel shell through the oil groove 5 of the rear gear ring 7 and then flows out from the oil groove 5 of the front gear ring 11, so that the one-way clutch 9 is kept in a lubricating state all the time during working.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the principles of the invention, and it is intended to cover all such changes and modifications as fall within the scope of the invention.
