(Ql. 29522) The invention disclosed herein relates to a process for securing two members together.
More particularly, the invention relates to a process for fixedly locating a member in a bore.
An object of the invention is to provide a process for securing a member to the wall of a wheel cylinder.
Another object of the invention is to provide a process for securing an element to the wall of a bore of a body member wherein pressure is applied to one face of the element to expand or swedge the outer periphery of the element into engagement with the wall while the element is supported by support means other than that forming the finished assembly.
A still further object of the invention is to provide a process for securing an element to the wall of a bore within a body member wherein pressure is applied to one face of the element to expand or swedge the outer periphery of the element into engagement with the wall while the other face of the element is supported about its outer periphery by a stationary ram and at its central portion by a yieldable take-up ram.
Other objects and features of the invention will become apparent from a consideration of the following description, which proceeds with reference to the accompanying drawings, wherein:
FIGURE 1 illustrates a battle member secured to the wall of a bore of a wheel cylinder;
FIGURE 2 illustrates a plan view of the bafiie member;
FIGURE 3 illustrates a section taken on line 3-3 of FlGURE 2;
FIGURE 4 illustrates the position of the rams and bafide member prior to application of pressure to secure the bafi'ie member to the wall of the bore of a wheel cylinder; and
FIGURE 5 illustrates the position of the rams and baffle member after pressure has been applied to secure the baffle member to the wall of the bore of the wheel cylinder.
With reference to FIGURE 1, there is illustrated a bafiie member lil secured into a groove 11 of a wall 12 of a bore in a wheel cylinder housing 14. The purpose of the baffle member is to retard movement or" the secondary shoe toward the anchor pin to eliminate noise or clunk. The battle member 19 is located between the inlet port 39 of the wheel cylinder housing 14 and the piston 13 which is to be connected to a secondary shoe (not shown). The battle has a small opening 26 therein which allows passage of oil from the chamber 15 to the chamber 17 and conversely. Upon application of the brake, oil will first pass from chamber 15 to chamber 1", to spread the shoes and as the secondary shoe is forced toward the anchor pin the bathe will act as a dashpot slowing the passage of oil from chamber i? to chamber 15 and therefore the movement of piston 13 toward the center and movement of the secondary shoe toward the anchor pin. The invention relates to a process for securing the well known assembly of the baffle it and the wheel cylinder housing 14 together.
The bathe member 1% illustrated in FIGURES 2 and 3, has a central portion 16 axially ofiset from the outer periphery 13. A notch 23 is impressed in the bafile mem- 3,l5,3l Ratented Dec. 1, 1964 her for registering with a corresponding notch 22 of a take-up ram 24 thereby locating the battle member 10 radially relative to the take-up ram 24. The opening 26 is located on the annular surface 28 of the bafile member.
With reference to FIGURE 5, there is provided a stationary ram 39 surrounding a movable take-up ram 24 which is supported by a member of resilient material 34. A bracket 31; is connected to base 42 and is so shaped that the wheel cylinder housing 14 may be placed over the stationary and take-up rams in one radial position only and located axially with respect to the stationary ram. The boss 38 has been shown in simplified form omitting the inlet 4% and a bleed port for the purposes of clarity. The base 42 is mounted to a stationary structure.
in performing the process of securing the bafiile member ill to the groove 11 of the wheel cylinder housing 14, the baflle member 16 is placed on the take-up ram 24 and the stationary ram 36 with the notch 20 of the bafiie member being matched with the notch 22 of the take-up ram 24. The bafiie member it will have its inner face 44 of the central portion 16 and its inner face d6 of the annular surface 23 engaging the take-up ram 24 and will have the inner face 43 of its outer periphery 18 engaging the stationary ram 30. The wheel cylinder housing is then inserted over the stationary ram 30, take-up ram 24 and the bathe member 10 or another way of positioning the bafile and cylinder housing on the take-up and stationary rams would be to place the wheel cylinder housing over the stationary and take-up rams 30 and 24 respectively, and then insert the baffle member 16 through the opening 52 and place it on the stationary and take-up rams. The outer periphery 18 of the bafiie member will talte a position contiguous the groove 11 of the wall 12 and the opening 26 will be oriented correctly with respect to the wheel cylinder housing 14 due to the notch fitting Zil, 22 of the bathe plate and the take-up ram and the radial and axial positioning of the wheel cylinder housing by the bracket 36. A driving ram 50 is inserted through the opening 52 of the housing 14 and brought into engagement with the baflie member 19. FIGURE 4 illustrates the positions of the bathe member, driving ram, take-up ram, stationary ram and groove prior to the application of pressure to the driving ram 5%.
When pressure P is applied to the driving ram 59, the driving ram 59 presses the central and annular surface 16 and 25 of the battle member against the take-up ram 24 compressing the resilient member 34 and at the same time applies force against the outer periphery 13 of the bafiie member against the stationary ram 30 thereby expanding or swedging the outer periphery 18 into the annular groove 11 of the wall 12, as illustrated in FEGURE 5. It should be noted that the sole support for the bafile member during the application of force by the driving ram 5d are the driving and take-up rams which do not form any part of the wheel cylinder housing, or in other Words do not form any part of the member to which the battle member is secured.
It should be noted that this process need not necessarily be used in conjunction with a groove such as groove 11 of the housing 14 but could be used for swedgin g the outer periphery of the baffle member into a frictional fit with the wall of the bore 12. Furthermore, while the process has been demonstrated connection with fixedly locating a bathe to a wheel cylinder, the process disclosed may be used where any member is to be secured to the bore of any body member.
It is intended that such revisions and variations of the invention, which incorporate the herein disclosed principles, as are reasonably to be expected on the part of those skilled in the art will be included within the scope of the following claims.
