Description
本創作係關於一種用於具兩前輪載具之轉向機構，尤指一種可控制載具之兩前輪轉向之轉向機構。This creation relates to a steering mechanism for two front wheel vehicles, and more particularly to a steering mechanism that can control the steering of two front wheels of the vehicle.
目前所見之機動載具均為前後輪之設置型態，然為不同的用途，即有一前輪、一後輪標準型態之機動載具，或適用於特殊地形之二前輪、二後輪之機動載具，然鑑於一前輪、一後輪之機動載具於暫停時，須以腳著地的方式來支撐，即有業者進一步開發出二前輪、一後輪之機動載具。The mobile vehicles currently seen are all front and rear wheel settings, but for different purposes, that is, a front wheel, a rear wheel standard type of mobile vehicle, or two special front and two rear wheels Vehicles, however, in view of the suspension of a front wheel and a rear wheel, they must be supported by foot and land, that is, the manufacturer has further developed the second and the rear wheel of the mobile vehicle.
而上述屬二前輪之兩種型態之機動載具，與一前輪的機動載具，設計上最大的差別，在於載具轉向或傾時，其靈活性不如一前輪的機動載具，因此業者莫不致力於轉向機構及傾斜機構之研發，以期使兩前輪之機動載具控制更加順暢及靈活。The biggest difference between the two types of mobile vehicles of the two front wheels and the mobile vehicle of the front wheel is that the vehicle is not as flexible as a front wheel mobile vehicle when the vehicle is turning or tilting. We are not committed to the development of steering mechanisms and tilting mechanisms, in order to make the control of the mobile vehicles of the two front wheels more smooth and flexible.
其中轉向機構設計上最大的考量，在兩前輪的連動性，若無法使兩前輪保持於特定的連動關係，勢必使載具難以操控，因此以往所見之轉向機構係於轉向桿前端樞設一轉向架座，轉向架座兩端分別樞設於兩側前輪的懸吊機構上端處，藉此使轉向桿、轉向機構、轉向架座及兩前輪保持於連動狀態，當控制轉向桿轉動時，即同時帶動兩前輪轉向。Among them, the biggest consideration in the design of the steering mechanism, in the linkage of the two front wheels, if the two front wheels can not maintain a specific linkage relationship, it is bound to make the vehicle difficult to control, so the steering mechanism seen in the past is pivoted at the front end of the steering rod. The pedestal, the two ends of the bogie seat are respectively pivoted at the upper ends of the suspension mechanisms of the front wheels on both sides, thereby keeping the steering rod, the steering mechanism, the bogie seat and the two front wheels in a linked state, when the control steering lever is rotated, At the same time, the two front wheels are turned.
惟，兩前輪除了藉由懸吊機構與轉向桿所傳動之各機構銜接外，兩前輪係分別與地面接觸，因此兩前輪分別與地面的關係，也會影響兩前輪機動載具之轉向，因此在轉向桿直接操控轉向機構時，若兩前輪與地面的相對狀況不同，而傳達不同的反作用力時，在傳統的轉向架座本身為剛性設計的情況下，會導致轉向桿難以靈活地控制轉向。However, the two front wheels are connected to the ground by the suspension mechanism, and the two front wheels are respectively in contact with the ground. Therefore, the relationship between the two front wheels and the ground also affects the steering of the two front turbine moving vehicles. When the steering rod directly controls the steering mechanism, if the two front wheels are different from the ground and convey different reaction forces, the traditional steering frame itself is rigid and the steering rod is difficult to flexibly control the steering. .
為此，即有業者研發出一種轉向機構，其係於轉向架座上設置一樞轉裝置，該樞轉裝置於轉向架座之中央處形成球狀孔，於球狀孔處配設一支撐桿，該支撐桿與轉向桿樞接，且支撐桿與球狀孔間係以球形面接觸，使轉向架座與支撐桿間形成正交的轉動軸線，藉以增加轉向角度以提升操控性，並能吸收衝擊力。To this end, a manufacturer has developed a steering mechanism that is provided with a pivoting device on the bogie mount. The pivoting device forms a spherical hole at the center of the bogie mount and a support at the spherical hole. a lever, the support rod is pivotally connected to the steering rod, and the support rod and the spherical hole are in contact with the spherical surface, so that an orthogonal rotation axis is formed between the bogie seat and the support rod, thereby increasing the steering angle to improve the handling property, and Can absorb impact.
然前述之轉向機構，其轉向架座除了中央與支撐桿間呈萬向的樞接狀態外，轉向架座本身仍是剛性構件，並仍是以兩端分別與兩前輪懸吊機構樞接，因此，兩前輪分別傳達之反作用力，仍受限於轉向架座的剛性傳達，而無法適時地分別抵消，因此，並無法達到預期的功效。However, in the foregoing steering mechanism, the bogie seat is in the form of a universal joint between the center and the support rod, and the bogie seat itself is still a rigid member, and is still pivotally connected to the two front wheel suspension mechanisms at both ends. Therefore, the reaction forces transmitted by the two front wheels are still limited by the rigidity of the bogie seat, and cannot be offset in time, so that the expected effect cannot be achieved.
鑑於現有轉向機構之問題，本創作者乃研發出本創作用於具兩前輪載具之轉向機構，本創作轉向機構之轉向架係為左右各一之設置，並以主樞接組件將左、右轉向架樞接呈連動狀態，而藉由主樞接組件與左、右轉向架之樞接座間之球面樞接關係，既可使轉向桿之轉向動作傳達至兩前輪處，可藉樞接處產生之些微變化，使轉向桿之操控不會受到影響，且當載具處於傾斜狀態時，此轉向機構不受載具之傾斜機構影響，仍可依循原操控之軌跡進行轉向，提供一實用之轉向機構。In view of the problem of the existing steering mechanism, the creator developed the steering mechanism for the two front wheel vehicles. The steering frame of the present steering mechanism is set to the left and right, and the main pivoting assembly will be left, The right bogie is pivotally connected, and the spherical pivotal relationship between the main pivoting assembly and the pivoting seats of the left and right bogies can convey the steering action of the steering rod to the two front wheels. Some slight changes in the pivoting position make the steering lever control unaffected, and when the vehicle is tilted, the steering mechanism is not affected by the tilting mechanism of the carrier, and can still be steered according to the original trajectory.

Therefore, as shown in FIG. 6, the right connecting frame 50 and the right connecting arm 221 are pivotally connected, wherein the outer side of the right connecting frame 50 is formed to extend up and down. The hollow sleeve 54 is provided with a bearing 541, 542 on the upper and lower sides of the sleeve 54. The other right engaging arm 221 correspondingly forms a coupling seat 222 having a middle hole, and the fixing screw 55 can be sequentially inserted into the bearing 541 and the sleeve from the upper end. 54, the bearing 542 and the adapter seat 222, and then the fixing screw 55 is locked and fixed by the nut 551, even if the outer side of the right adapter 50 is pivotally connected with the right connecting arm 221; please also refer to FIG. 8 , the right support bar 22 The right front wheel 71 and the left front wheel 81 are engaged with the bottom end of the left support rod 23 by the right suspension mechanism 70 and the left suspension mechanism 80, respectively.
故本創作之轉向機構於與轉向桿連動之定位架上，請配合參看圖1及圖2所示，藉由主樞接組件40銜接右轉向架43及左轉向架45，而右轉向架43與左轉向架45間又以對應之樞接座來樞接，因此整個轉向機構非呈剛性，兩側之轉向架間藉由主樞接組件40與兩側樞接座之樞接為球面的套接關係，而存在些微的作動餘隙度，因此，縱使兩側轉向架分別以銜接架，而與兩側支撐桿上所延伸之銜接臂樞設呈連動狀態，如圖8所示，但當旋轉轉向桿21而藉由轉向機構帶動右前輪71及左前輪81轉向時，如圖9及圖10所示，縱使右前輪71及左輪81因與地面的相對狀況不同，而傳達不同的反作用力時，傳達至主樞接組件40與右樞接座44、左樞接座46之樞接處，即可藉由二樞接座間之作動餘隙度而達到平衡，使轉向桿之操控靈活性不會受到影響。Therefore, the steering mechanism of the present invention is placed on the positioning frame interlocked with the steering rod. Please refer to FIG. 1 and FIG. 2, and the right pivot frame 43 and the left bogie 45 are connected by the main pivoting assembly 40, and the right turn is turned. The frame 43 and the left bogie 45 are pivotally connected by the corresponding pivoting seats, so that the entire steering mechanism is not rigid, and the bogies on both sides are pivoted by the main pivoting assembly 40 and the pivoting seats on both sides. Connected to the spherical socket relationship, there is a slight movement clearance, therefore, even if the two side bogies are respectively connected to the bracket, and the connecting arms extending on the two side support rods are pivoted together, as shown in Figure 8. As shown in the figure, when the steering lever 21 is rotated and the right front wheel 71 and the left front wheel 81 are turned by the steering mechanism, as shown in FIGS. 9 and 10, the right front wheel 71 and the left wheel 81 are different from each other due to the relative situation with the ground. When the different reaction forces are transmitted, the pivotal connection between the main pivoting assembly 40 and the right pivoting base 44 and the left pivoting seat 46 can be balanced by the actuating clearance between the two pivoting seats to make the steering The handling flexibility of the lever is not affected.
且因本創作之轉向機構非剛性之型態，故當機動載具處於傾斜狀態時，如圖11所示，本創作之轉向機構10不受機動載具之傾斜機構90影響，仍可依循原操控之軌跡進行轉向。And because the steering mechanism of the present invention is non-rigid, when the mobile vehicle is tilted, as shown in FIG. 11, the steering mechanism 10 of the present invention is not affected by the tilting mechanism 90 of the mobile vehicle, and can still follow the original The trajectory of the steering is turned.
因此，本創作之轉向機構將原剛性之轉向架以樞接型態之左轉向架及右轉向架來取代，藉由各樞接點之銜接關係，仍將轉向桿所傳達的轉向動作，正確地傳達至兩前輪處，故藉由兩側轉向架間之樞接處所產生之些微變化，而使轉向桿之操控不會受到影響，提供一更符合所需之轉向機構。Therefore, the steering mechanism of the present invention replaces the original rigid bogie with the pivotal left bogie and the right bogie, and the steering action conveyed by the steering rod is still achieved by the joint relationship of the pivot joints. It is correctly transmitted to the two front wheels, so that the steering of the steering lever is not affected by the slight changes caused by the pivotal joints between the bogies on both sides, providing a steering mechanism more suitable for the required.
