  一後輪懸吊避震機構60(如第一、三、四圖所示),係於固定左、右後輪4的後輪架40上方,分別連接有一液壓阻尼器61(即後輪避震器),該液壓阻尼器61的另一作用端與車架2樞接,且二液壓阻尼器61的液壓油管相通,避震作用力相互傳遞互補,藉此將左、右後輪4懸吊定位及具避震效果。
  一控制左、右前輪3轉向的前輪轉向機構70,如第三、四、六圖所示,係具有一彎狀搖板71,該搖板71的中間與車架2樞接,頂面與控制機車轉向的機車把手20之轉向軸21固接,俾該搖板71可隨把手20的轉向而在原地左、右擺動;具二方向連桿72,每一支方向連桿72的一端與該搖板71的一端樞接,另一端與同側的前輪架30樞接,俾機車把手20轉向時,可控制搖板71以樞接點為軸心同步轉向,續而連動二方向連桿72驅動左右前輪架30、左右前輪3同步轉向。
  當將上述構件依序組合後,即如第一~三圖所示,搭配引擎驅動可控制左、右輪轉速不同的差速器,俾當左、右前輪3及後輪4行駛在顛簸路面作動如第七圖所示,若其中一輪遇到高突路面,該輪會順著路面往上將上方的避震器51壓縮(如第八圖所示);若輪子滾過的高突路面高度大於避震器51的避震壓力,則如第九圖所示,該輪的避震器51會將扁擔架52樞接端往上頂,該扁擔架52的另一相對端則下移,微下壓另一前輪的避震器51,致兩前輪3能同時著地;而左、右後輪4經過高突路,亦如左、右前輪3一樣,液壓阻尼器61可對後輪4產生避震效果,使後輪4保持著地,而且,二液壓阻尼器61油路互通,亦如該扁擔架52般,具有避震壓力傳遞互補的效果。
  當機車把手20轉向控制時(如的六圖所示),機車把手20的轉向軸21會連動搖板71隨著把手20的轉向而原地移動,搖板71擺動,二方向連桿72會同步驅動左、右前輪3同步轉向,如第十、十一圖所示。
  由上列的說明可知,本發明因車輪懸吊裝置5的前輪懸吊避震機構50及後輪懸吊避震機構60之設置,致左、右側的前、後輪3、4可因所經過的不同路況而作獨立上、下位移及著地。而且前輪轉向機構70的設置,使左、右前輪3可同步轉向外,復可左、右輪同步轉向並各別獨立上下位移,使四輪速克達機車於不同路況皆可保持四輪著地,以保持操控的靈活、安全性。
  綜觀上述,本發明不僅具發明性且具產業利用性,誠已符合發明專利要件,依法提出發明專利申請,謹請惠予核准。
The following is an explanation of the technical means for achieving the above objects and effects, and the following embodiments are described below with reference to the drawings.
Referring to the first to fourth figures, the four-wheel speed locomotive 1 has left and right front wheels 3 at the front end of the frame 2, and left and right rear wheels 4 at the rear end. A wheel suspension device 5 for fixing a wheel, comprising:
A front wheel suspension suspension mechanism 50 (shown as shown in the first, second, and fifth figures) is attached to the left and right front wheel frames 30 respectively connected to the left and right front wheels 3, and each of the pivots has a vertically disposed front wheel avoidance mechanism. The other end of the two front wheel suspensions 51 is connected to one end of a flat stretcher 52. The middle of the flat stretcher 52 is pivotally connected to the frame 2, and the left stretcher 52 is disposed to the left. The right front wheel 3 is suspended and the shock-absorbing forces of the two front wheel shock absorbers 51 are mutually complementary, so that the left and right front wheels 3 have a shock-absorbing and shock-absorbing effect.
A rear wheel suspension suspension mechanism 60 (shown in Figures 1, 3, and 4) is attached to the rear wheel frame 40 of the fixed left and right rear wheels 4, and is respectively connected with a hydraulic damper 61 (ie, rear wheel avoidance) The other end of the hydraulic damper 61 is pivotally connected to the frame 2, and the hydraulic oil pipes of the two hydraulic dampers 61 are connected, and the suspension force is mutually transmitted and complemented, thereby suspending the left and right rear wheels 4 Hang positioning and shock absorber effect.
A front wheel steering mechanism 70 for controlling the steering of the left and right front wheels 3, as shown in the third, fourth, and sixth figures, has a curved rocking plate 71, and the middle of the rocking plate 71 is pivotally connected to the frame 2, and the top surface is The steering shaft 21 of the locomotive handle 20 for controlling the steering of the locomotive is fixed, and the rocking plate 71 can swing left and right in the same direction as the handle 20 is turned; there is a two-directional link 72, one end of each of the directional links 72 is One end of the rocking plate 71 is pivotally connected, and the other end is pivotally connected with the front wheel frame 30 on the same side. When the locomotive handle 20 is turned, the rocking plate 71 can be controlled to pivot with the pivot point as the axis, and the two-way link is continuously connected. 72 drives the left and right front wheel frames 30 and the left and right front wheels 3 to rotate synchronously.
When the above components are sequentially combined, as shown in the first to third figures, the engine drive can control the differentials with different left and right wheel speeds, and the left and right front wheels 3 and the rear wheel 4 travel on the bumpy road surface. As shown in the seventh figure, if one of the wheels encounters a high-bend road surface, the wheel will compress the upper shock absorber 51 along the road surface (as shown in the eighth figure); if the wheel rolls over the high-profile road surface If the height is greater than the shock pressure of the shock absorber 51, as shown in the ninth figure, the shock absorber 51 of the wheel will lift the pivotal end of the flat stretcher 52 upward, and the other opposite end of the flat stretcher 52 will move down. The lower shock absorber 51 of the other front wheel is pressed slightly, so that the two front wheels 3 can land at the same time; and the left and right rear wheels 4 pass through the high protruding road, like the left and right front wheels 3, and the hydraulic damper 61 can be rearward. The wheel 4 generates a shock absorbing effect, so that the rear wheel 4 is held to the ground, and the oil passages of the two hydraulic dampers 61 are intercommunicated, and as with the flat stretcher 52, the suspension pressure transmission is complementary.
When the locomotive handle 20 is turned to control (as shown in FIG. 6), the steering shaft 21 of the locomotive handle 20 will move the rocking plate 71 to move in place as the handle 20 is turned, the rocking plate 71 swings, and the two-direction link 72 will The left and right front wheels 3 are synchronously driven to synchronously turn, as shown in the tenth and eleventh figures.
As can be seen from the above description, the present invention is provided by the front wheel suspension suspension mechanism 50 and the rear wheel suspension suspension mechanism 60 of the wheel suspension device 5, so that the front and rear wheels 3 and 4 of the left and right sides can be used. Independent upper and lower displacements and landings are carried out under different road conditions. Moreover, the front wheel steering mechanism 70 is arranged such that the left and right front wheels 3 can be synchronously turned outside, and the left and right wheels can be synchronously steered and independently displaced up and down, so that the four-wheel speed keda locomotive can maintain four wheels in different road conditions. Ground to maintain flexibility and security.
Looking at the above, the present invention is not only inventive but also has industrial applicability. Cheng has already met the requirements for invention patents, and has filed an invention patent application according to law, and I would like to request approval.
