Abstract
The utility model relates to a novel cover wheel of a hydraulic torque converter, which belongs to the technical field of parts of a rotary fluid transmission device. The novel cover wheel comprises an end lid and a cover shell which are riveted with each other, wherein the cover shell is provided with reinforcing ribs; and a circle of tiny element rest is formed on the combined surface of the cover shell and a pump wheel. The novel cover wheel of a hydraulic torque converter comprises the end lid and the cover shell which are riveted, and the reinforcing ribs are additionally arranged on the cover shell, so that the product strength is improved. An O-shaped seal ring is replaced by the circle of tiny element rest formed on the combined surface of the cover wheel for sealing. The novel cover wheel of a hydraulic torque converter satisfies the requirements for various technical indexes, reduces impurities caused by butter to improve the product cleanliness, prolongs the service life of transmission oil, lowers the rejection ratio of the product and decreases the cost of production.
Description
Technical field
The utility model belongs to the component technical field of rotating fluid transmission device, is specifically related to a kind of novel hubcap of fluid torque converter.
Background technique
In the prior art, fluid torque converter is generally linked to each other with motor by hubcap by the revolving part pump impeller, carries out static seal with the O RunddichtringO between pump impeller and hubcap.Assembling uses butter that the O RunddichtringO is bonded in the hubcap seal groove when putting the O RunddichtringO, then is placed on the pump impeller, uses Bolt Connection.When carrying out cleanliness testing, find that the impurity weight that is caused by butter reaches more than 100 milligrams, make the turbidity test of product not reach requirement, easily make the transmission oil premature aging in the fluid torque converter simultaneously.In addition, hubcap adopts the cast inblock of HT300 cast iron, Heavy Weight, and reject rate is high.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defective of mentioning and deficiency, and provide a kind of novel hubcap of fluid torque converter, traditional fluid torque converter hubcap and hubcap and pump impeller end face seal are improved, made hubcap weight saving, the sealing of hubcap and pump impeller is more reliable simultaneously.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of novel hubcap of fluid torque converter, hubcap is formed by end cap and the riveted joint of case two-part, is provided with stiffening rib on the described case, and described case is provided with the small convex tendon of a circle at the junction plane with pump impeller.
The cross section of described convex tendon is isosceles trapezoid, and its base angle is 45 °, and height is 0.08mm, and the top is 0.1mm.
Described stiffening rib is arranged on the case around the equidistant circular row of running shaft.
Described stiffening rib is 8.
Compare with the hubcap of traditional fluid torque converter, the utility model product is formed by end cap and the riveted joint of case two-part, and has set up stiffening rib at case, has improved the intensity of product.Between the junction plane of hubcap and pump impeller, the junction plane of employing on hubcap arranges the small convex tendon of a circle and replaces the sealing of O RunddichtringO, when reaching all technical requirement, reduced the impurity that is caused by butter, the turbidity test of product have been improved, prolong the working life of transmission oil, and reduced the reject rate of product, reduced cost of production.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the utility model product;
Fig. 2 is convex tendon cross section, A place enlarged view among Fig. 1;
Among the figure: 1-end cap, 2-case, 21-stiffening rib, 22-convex tendon, 3-pump impeller, 4-nut, 5-compression spring, 6-flat gasket, 7-bolt, 8-rivet.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, because the continuous high and client of price of steel product is more and more higher to the requirement of turbidity test, the utility model improves the hubcap of fluid torque converter and the sealing of hubcap and pump impeller end face.Hubcap is formed by the case that strengthening rib is arranged 2 two-part riveted joint that end cap 1 and steel plate stretching form, and is provided with rivet 8 on the junction plane of end cap 1 and case 2.Original hubcap adopts the cast inblock of HT300 cast iron, 16 kilograms of net weight, and reject rate is high, now changes the steel part riveted joint into, and its net weight only has 9 kilograms, and all technical all reaches former technical requirements.Riveted joint has been avoided the impact of welding stress for product structure than welding.
Seal en-hancement for hubcap and pump impeller 3 end faces is to set up the small convex tendon 22 of a circle at the junction plane of hubcap and pump impeller 3.Connect with bolt 7, nut 4, spring washer 5, flat gasket 6 with the flange of pump impeller 3 in hubcap like this, the convex tendon 22 on the hubcap is because of stressed and pump impeller 3 junction plane close contacts and imbed, and substitutes the sealing of O RunddichtringO.Through test, under the 1MPa water pressure, pressurize 10 minutes and ne-leakage reaches all technical requirement fully.
As shown in Figure 2, the cross section of the convex tendon 22 that one on the junction plane of hubcap and pump impeller 3 circle is small is isosceles trapezoid, and as preferably, its base angle is 45 °, and height is 0.08mm, and upper base is 0.1mm.
Described stiffening rib 21 is arranged on the case 2 around the equidistant circular row of running shaft, and stressed even, stiffening effect is remarkable.It is one-body molded when stiffening rib 21 is the product punching press.As preferably, described stiffening rib 21 is 8.
The utility model is illustrated according to embodiment, and under the prerequisite that does not break away from the utility model principle, this product can also be made some distortion and improvement.Should be pointed out that all employings are equal to the technological scheme that the modes such as replacement or equivalent transformation obtain, and all drop in the protection domain of the present utility model.
