Abstract
Description
Technical Field
[0001] This disclosure relates to motorized graders. More specifically, this disclosure relates to a ring assembly for an implement of a motorized grader, an implement assembly for a motorized grader, and a mounting assembly for an implement of a motorized grader. Background Technology
[0002] Graders can be used for the construction and maintenance of various surfaces such as roads. These graders can be used to cut, spread, and level materials such as soil, gravel, and snow. To perform these tasks, graders include implements also known as plows. The implements are supported and positioned on the grader by various components including drawbars and ring assemblies.
[0003] The ring assembly includes a ring, a pair of side arms connected to the ring at opposite ends, and a pair of tool brackets. The tool brackets are removably connected to a corresponding side arm of the pair of side arms, and to a tool. Conventionally, each tool bracket is connected to its corresponding side arm via a pin. Specifically, the tool bracket is connected to its corresponding side arm via a single shear pin joint. Such a single shear pin joint exhibits limited durability and load-bearing capacity, which can cause damage to the side arms, tool brackets, and / or pins, and may reduce the lifespan of such components. During operation, the pin is subjected to significant shear loads due to this single shear pin joint, leading to shear failure of the pin. Failure of the pin, side arm, or tool bracket can increase maintenance costs and downtime associated with grader machinery.
[0004] GB561271A describes a bulldozer or side-shovel bulldozer in which the blade is carried by a frame and pivots to a subframe of a tractor's crawler track. When traversing uneven ground, the subframe is swaying relative to the tractor, and the position of the frame is controlled by a crank or rocker arm supported on the tractor, and preferably adjusted by a hydraulic cylinder. The swaying movement of the track subframe is compensated about the blade by a pivoting support, which is pivoted about each subframe and carries the corresponding crank and cylinder pivots. This support also pivots to a connecting rod that pivots to the tractor frame. Each support may include a yoke structure bridging the top of the corresponding subframe and includes V-shaped side plates welded to a channel member supporting the pivot. Summary of the Invention

[0017] In all the accompanying drawings, the same reference numerals will be used as much as possible to denote the same or similar parts.
[0018] refer to Figure 1 The image shows a perspective view of a motorized grader 100. The motorized grader 100 can be used to cut / dig the work surface and / or move snow, debris, etc., during the leveling process prior to road construction, without any limitations.
[0019] Motorized grader 100 includes a frame 102. Frame 102 defines a front end 104 and a rear end 106. Furthermore, motorized grader 100 includes two pairs of rear wheels 108 disposed near the rear end 106 and a pair of front wheels 110 disposed near the front end 104. The front wheels 110 and rear wheels 108 allow motorized grader 100 to move.
[0020] The frame 102 supports various components of the motor grader 100, such as a power source (not shown), operator's cab 114, front wheels 110, and rear wheels 108, all housed within the housing 112. The power source can be an engine, such as an internal combustion engine, a battery system, or a fuel cell. The power source provides output power to the various components of the motor grader 100 for their operation. Furthermore, the motor grader 100 includes an operator's cab 114. The motor grader 100 also includes a drawbar 116 connected to the frame 102. The drawbar 116 is connected to the frame 102 at its end 118 via a ball joint (not shown), allowing the drawbar 116 to pivot relative to the frame 102.
[0021] Now for reference Figure 2 The drawbar 116 includes one or more drawbar beams 120 and an annular mounting portion 122. The annular mounting portion 122 is circular in shape. Figure 2 In the illustrated example, the tow bar 116 includes two tow bar beams 120, but it should be understood that the tow bar 116 may include any suitable number of tow bar beams 120, or any other suitable configuration known to those skilled in the art. The tow bar 116 may include additional elements (not shown herein) that facilitate connection of the tow bar 116 to other components of the motorized grader 100 (see [link to documentation]). Figure 1 ).
[0022] The motorized grader 100 also includes an implement assembly 124. The implement assembly 124 is connected to a drawbar 116. The implement assembly 124 includes a ring assembly 126 for an implement 128 of the motorized grader 100. The implement assembly 124 also includes an implement 128 removably connected to the ring assembly 126. The implement 128 may include a blade or a plowshare. The implement 128 can be used to perform operations such as leveling or snow removal.
[0023] refer to Figure 3A The ring assembly 126 includes a ring 130. The ring assembly 126 also includes one or more mounting components 200, 201 to connect the ring 130 to the tool 128 (see [link]). Figure 2 Specifically, the annular assembly 126 includes a first mounting assembly 200 disposed on a first side 131 of the annular 130 and a second mounting assembly 201 disposed on a second side 132 of the annular 130. The mounting assembly 200 may be interchangeably referred to as "first mounting assembly 200" hereinafter. The mounting assembly 201 may be interchangeably referred to as "second mounting assembly 201" hereinafter. The first mounting assembly 200 and the second mounting assembly 201 are similar to each other in construction and function, and are symmetrical about the vertical axis A1.
[0024] Each of one or more mounting components 200, 201 includes a first bracket 202 coupled to an annulus 130. Each first bracket 202 is fixedly coupled to the annulus 130 at a first side 131 and a second side 132, respectively. In an example, each first bracket 202 is fixedly coupled to the annulus 130 by welding. However, any other joining technique besides welding may be used to fix the first bracket 202 to the annulus 130. The first bracket 202 defines a first distal end 204 and a second distal end 206, the second distal end being spaced apart from the first distal end 204 along the first bracket 202. The first distal end 204 is disposed adjacent to the annulus 130, and the second distal end 206 is disposed distal to the annulus 130. Specifically, the first bracket 202 is coupled to the annulus 130 near the first distal end 204.
[0025] Now for reference Figure 3A and 3B The first bracket 202 includes a first arm 208, a second arm 210 axially spaced from the first arm 208, and a third arm 212 connecting the first arm 208 and the second arm 210. The first bracket 202 also includes a fourth arm 213, which is spaced from the third arm 212 and connects the first arm 208 and the second arm 210. Figure 3A and 3B As shown, the first bracket 202 has a box-shaped cross-section along at least a portion of the first bracket 202. In other words, the first arm 208, the second arm 210, the third arm 212, and the fourth arm 213 together form a box-shaped cross-section. Furthermore, the second arm 210, the third arm 212, and the fourth arm 213 extend only along a portion of the first bracket 202. The second arm 210 extends from the second distal end 206 toward the first distal end 204. Furthermore, the first arm 208 extends from the first distal end 204 to the second distal end 206. The third arm 212 and the fourth arm 213 can be fixedly connected to the first arm 208 and the second arm 210, for example, by welding. Alternatively, the first arm 208, the second arm 210, the third arm 212, and the fourth arm 213 can be integral with each other.
[0026] In other instances, the first bracket 202 may include a C-shaped cross-section. In such instances, the first bracket 202 may omit the fourth arm 213 and include only the first arm 208, the second arm 210, and the third arm 212.
[0027] Refer again Figure 3A The first bracket 202 also includes a first bushing 214 coupled to the first arm 208. The first bushing 214 may be fixedly coupled to the first arm 208, for example, by welding. Alternatively, the first bushing 214 and the first arm 208 may be integral with each other. The first bushing 214 is disposed near the second distal end 206 of the first bracket 202. A portion of the first bushing 214 is received within the first arm 208 (in...). Figure 6(best visible in the middle), and the remainder of the first bushing 214 extends axially outward from the first arm 208. It should be noted that the first bushing 214 and the third arm 212 extend from the opposing surfaces of the first arm 208.
[0028] The first bracket 202 also includes a second bushing 216 coupled to the second arm 210. The second bushing 216 and the first bushing 214 are aligned with each other. The second bushing 216 can be fixedly coupled to the second arm 210, for example, by welding. Alternatively, the second bushing 216 and the second arm 210 can be integral with each other. The second bushing 216 is disposed near the second distal end 206 of the first bracket 202. A portion of the second bushing 216 is received within the second arm 210 (in... Figure 6 (best visible in the middle), and the remainder of the second bushing 216 extends axially outward from the second arm 210. It should be noted that the second bushing 216 and the third arm 212 extend from the opposing surfaces of the second arm 210.
[0029] refer to Figure 4A and 4B Each of one or more mounting components 200, 201 further includes a second bracket 218 removably coupled to the first bracket 202. The second bracket 218 is coupled to the tool 128. The second bracket 218 includes various elements that allow the second bracket 218 to be coupled to the tool 128. The second bracket 218 includes a body 220. The body 220 is a single integral element defining the first member 222, the second member 224, and the third member 226.
[0030] like Figure 4B As shown, each second bracket 218 has a substantially triangular profile. A first member 222 and a second member 224 extend at an angle to each other from a first vertex portion 228 of the body 220. Additionally, a third member 226 extends at an angle to the first member 222 from a second vertex portion 230 to connect the second member 224 at the third vertex portion 232, thus giving the second bracket 218 a substantially triangular profile. The first member 222 of the second bracket 218 includes a pair of portions 219 axially spaced apart from each other to accommodate a cylinder body 240 therebetween. Figure 5 (As shown in the figure). Similarly, the second member 224 of the second bracket 218 may also include a pair of portions (not shown herein) axially spaced apart from each other to accommodate the cylinder 240 therebetween. It should be noted that the second bracket 218 may have any other design or profile as required.
[0031] like Figure 4A and Figure 5As shown, each of the one or more mounting components 200, 201 further includes a fastener 234 that removably connects the first bracket 202 to the second bracket 218 via a first arm 208 and a second arm 210. The first bracket 202 is removably connected to the second bracket 218 near a third apex portion 232. Furthermore, the first bracket 202 is connected to the second bracket 218 via the fastener 234, such that the second bracket 218 pivots / hinges relative to the first bracket 202 about axis A2. By means of the hinge of the second bracket 218 relative to the first bracket 202, the second bracket 218 can at least partially facilitate the tool 128 relative to the frame 102 (see [link to documentation]) during leveling operations. Figure 1 ( ) or the tilt of the working surface. Fastener 234 is referred to herein as pin 234. Fastener 234 may be interchangeably referred to as "pin 234" hereinafter. In addition, pin 234 includes body portion 236 ( Figure 6 (shown in the image) and head portion 238 ( Figure 6 (as shown in the image).
[0032] like Figure 5 As shown, each of the one or more mounting assemblies 200, 201 further includes a cylinder 240, which is coupled to a first bracket 202 at a first end (not shown herein) and to a second bracket 218 at a second end 242. During operation of the motorized grader 100 (see...), Figure 1 During this period, 128 pieces of equipment (see...) Figure 2 and Figure 4A The implement 128 can be moved to many positions. For example, by sliding the implement 128 laterally (using cylinder 240), the implement 128 can move toward the left or right side of the motorized grader 100. Furthermore, the ring assembly 126 includes a plate 246 fixedly connected to the ring 130 and each first bracket 202. In an example, the plate 246 can be fixedly connected to the ring 130 and each first bracket 202 by welding.
[0033] Now for reference Figure 6 The first bracket 202 defines a first through hole 248 and a second through hole 250. Specifically, a first bushing 214 defines the first through hole 248, and a second bushing 216 defines the second through hole 250. Furthermore, a second bracket 218 defines a third through hole 252. The third through hole 252 is defined proximal to the third apex portion 232. Moreover, each of the first through hole 248, the second through hole 250, and the third through hole 252 is aligned with each other to receive a fastener 234.
[0034] like Figure 6As shown, when fastener 234 is connected to the first bracket 202 and the second bracket 218, a portion of the second bracket 218 is axially disposed between the first arm 208 and the second arm 210. Specifically, the third apex portion 232 is at least partially disposed between the first arm 208 and the second arm 210. Furthermore, when fastener 234 is connected to the first bracket 202 and the second bracket 218, fastener 234 is at least partially disposed in the first bushing 214. Furthermore, when fastener 234 is connected to the first bracket 202 and the second bracket 218, fastener 234 is at least partially disposed in the second bushing 216. Furthermore, when fastener 234 is connected to the first bracket 202 and the second bracket 218, the head portion 238 of pin 234 is disposed adjacent to the first bushing 214.
[0035] Each of one or more mounting assemblies 200, 201 further includes a first bearing 254 radially disposed between the first bushing 214 and the fastener 234. The first bearing 254 is received within a first through hole 248.

Specifically, the second bracket 218 is removably coupled to each of the first arm 208 and the second arm 210 via a double shear pin joint. Such a double shear pin joint increases the durability of the joint between the first bracket 202 and the second bracket 218.
[0039] Furthermore, the design of the first bracket 202, which allows for the connection of the first bracket 202 and the second bracket 218, can increase the load-bearing capacity and service life of the joint between the first bracket 202 and the second bracket 218. Additionally, the design of the first bracket 202 and the second bracket 218 as described herein can reduce the probability of joint failure between the first bracket 202 and the second bracket 218, which in turn can reduce the maintenance and repair costs associated with the motorized grader 100.
[0040] The first bracket 202 described herein includes a sub-assembly box structure that can protect the cylinder 240 by improving load distribution in the annular assembly 126. Furthermore, the double shear pin joint provided by the mounting assemblies 200, 201 of this disclosure is easy to manufacture, can be cost-effectively incorporated, and can eliminate bending of the fastener 234 by improving the load-bearing capacity of the joint between the first bracket 202 and the second bracket 218. The mounting assemblies 200, 201 of this disclosure can also improve the uptime of the motorized grader 100.
