The standing stand of the two-wheeled locomotive mounted on the power unit is improved. [Prior art] In a two-wheeled locomotive, a person who mounts a standing bracket on a power unit, for example, disclosed in Japanese Patent Laid-Open No. 5-2 4 6 3 5 9 is known [Content of the Invention] (Problem) Installing a stand bracket on the power unit, for example, can be integrated with the crank case of the engine to support the stand bracket, which is more cost effective than the case where the stand bracket is welded to the frame to support the hub. advantageous. However, when the standing device is installed on the power unit, the weight of the standing frame will affect the load of the rear bumper, that is, the load under the spring will increase. Therefore, when the standing device is installed on the power unit, it is strongly required that the standing frame be lightweight. The present invention has been made in view of this situation, and an object thereof is to make a station stand of a two-wheeled locomotive which can reduce the weight of the stand stand as much as possible and can be simply mounted on a power plant. (Means for solving the problem) 312 / Invention specification (Supplement) / 92-07 / 92112832 Change to support the safety and security in total, and to stand on the stand 200307618 In order to achieve the above purpose, the present invention is based on: the engine; and the shaft connection Rear wheel speed changer; the front of the power casing formed in this way forms a pair of left and right hanger arms, which are rotatably connected to the frame by horizontal hanger arms, etc. A rear bumper that cushions the device from shaking up and down. In this car, on the left and right pair of hanger arms, the base of the pair of hanger arms is formed at a greater interval than the pair of bearing parts supported on the pivot of the bracket arms. A pair of left and right standing bracket support wheels are connected to each other through the support shaft to rotate between the standing upright position and the storage position. This is its first special feature, and the aforementioned casings and pivots correspond to each other. The crank case 10 and the second pivot in the present example described later. According to this first feature, since the left and right hanger arms are integrally formed on the housing by a large distance between the left and right bearing portions of the pivot, the support of the power unit can be improved by the pivot, and the power unit can be given. I often shake my posture from above and below for a good ride. In addition, on the two hanger arms, since a pair of left and right standing stand supports are supported by a support shaft, it is not necessary to form a stand stand support wheel on the case to simplify the shape of the case, which can be further sought. The cost of casting is reduced. In particular, the rigid bases of the left and right hanger arms of the left and right standing bracket support wheels are formed side by side at a narrower distance than the two bearings. Therefore, the bases of the standing supports supported by the hubs supported by these stands can be used. The end is made narrower 312 / Invention Specification (Supplement) / 92-07 / 92112832. The pivot of the casing placed on the output causes the two turbines of this force device to be narrowed (boss) by these suspensions. Sign. Obviously, the implementation force is obtained by the rigidity of the power pack, and the good body can be formed with the holding wheel valley and the hub, which can be facilitated. The hub is spaced by the width of the stand bracket, and 6 200307618 can reduce the weight of the stand bracket. Quantification. Therefore, the load on the rear bumper can be reduced and the riding feeling can be improved. Furthermore, in addition to the first feature of the present invention, the hub of the standing stand supported by the support shaft is arranged between a pair of standing stand supporting bosses. This is the second feature. According to the characteristics of this brother, since the protruding surface of the standing bracket is arranged between the left and right standing bracket support bosses, it can be used as a short protruding surface, and the weight of the standing bracket can be further reduced. At the same time, The protruding surface can be easily positioned between the two supporting brackets of the standing bracket, and the two supporting brackets of the standing bracket can have good assemblability. In addition, in addition to the first or second feature of the present invention, a standing plate is provided with a reinforcing plate connecting the protruding surface and the left and right support feet, and a stand stand is formed on the hanger arm to abut against the reinforcing plate. The position stopper is the third feature. According to this third feature, the reinforcing plate connecting the protruding surface and the support foot can be used as a stopper plate that also serves as a standard stand-up stand, and the structure of the stand stand can be simplified. Furthermore, in addition to any one of the features of the first to third aspects of the present invention, the hanger arms on the left and right sides are formed in a narrow and narrow figure shape from the bearing portion toward the base portion at intervals on both sides in plan view. According to this fourth feature, the left and right hanger arms can increase the mutual rigidity in the lateral direction by the connecting pivot. At the same time, because the left and right standing brackets support the hub are formed on the narrow base between the two hanger arms, it is possible to Lighten the standing stand and achieve strong support. 7 312 / Invention Specification (Supplement) / 92-07 / 92112832 200307618 [Embodiment] The following describes an embodiment of the present invention with reference to an embodiment of the present invention shown in the drawings.

The left and right hanger arms 17 and 17 are designed to obtain the distance L 1 between the two bearing portions 17 a and 17 a supported on the second pivot shaft 15 as much as possible, and can be integrally formed on the crank case 10, With the second pivot 15, the support rigidity of the power unit P can be improved, and the power unit P can be constantly shaken above and below the stable position, and a good riding feeling can be obtained. In particular, since the left and right hanger arms 17 are formed to be spaced apart from each other in plan view, they become narrow and slightly splayed from the bearing portions 17 a and 17 a toward the base. Therefore, the second pivot The state in which 15 is connected to the suspension ring 13 increases the mutual rigidity in the horizontal direction, and further strengthens the supporting rigidity of the power unit P. In addition, since the two hanger arms 17 and 17 are integrally formed with a pair of left and right standing bracket support hubs 19 and 19 that support the protruding surface 22 of the standing bracket 9 by a support shaft 25, the crank case 1 It is not necessary to form a standing bracket to support the hubs 19 and 19 on 0, but the shape of the crank case 10 can be simplified, which can further facilitate the casting and reduce the cost. Moreover, the left and right standing bracket support hubs 19, 19 are arranged at narrower intervals on the base portions of the left and right hanger arms 17 and 17 that are relatively stiffer than the interval L1 between the two bearing portions 17a and 17a. As a result, the base ends of the standing brackets 9 connected to the stand brackets 9 and 19 by the stand 11 312 / Invention Specification (Supplement) / 92-07 / 92112832 200307618 can be made smaller. Width, so that the standing support 9 can be lightweight and the standing support 9 can have strong supportability. At this time, especially the protruding surface 22 of the standing bracket 9 is arranged between the two standing bracket supporting hubs 19 and 19, so the short protruding surface 22 can be used, and the weight of the standing bracket 9 can be further reduced. At the same time, The protruding surface 22 can be easily positioned between the two standing bracket holding hubs 19 and 19, and the two standing support supporting hubs 19 and 19 have good assembly properties for the standing bracket 9. In the standing bracket 9, since the front reinforcing plate 23 connecting the protruding surface 22 and the supporting feet 21 2 1 abuts the standing stopper of the crank case 10, the standing position A of the standing bracket 9 is regulated. The reinforcing plate 23 can also serve as a stopper plate, and the structure of the standing bracket can be simplified. The present invention is not limited to the embodiments described above, and various design changes can be made without departing from the scope of the gist. (Effects of the Invention) According to the first feature of the present invention as described above, a pair of left and right hangers is formed on the front of the power unit outside the front portion of the power unit so that the engine; and the transmission with the rear wheels connected to the transmission shaft. The arms can be rotatably connected to the frame through a horizontal pivot, and a rear bumper can be installed between the frame and the power device to buffer the device from shaking up and down. In a locomotive, a pair of left and right standing brackets are integrally formed on the base of the left and right pair of hanger arms at a narrower interval than a pair of bearing portions supported by the pivots of the hanger arms. Support the hub, and wait for the stand bracket to support the stand by the support shaft to make the stand bracket in the upright position 312 / Invention Manual (Supplement) / 92-07 / 92112832 This position 12 200307618 and the storage position are supported by the housing of the frame device, which can give a good ride with a pivot hub, so that the formation cost of the housing is reduced. The right hanger arm is narrower and lighter than the hub stand. In addition, according to the standing bracket which is supported by the standing bracket between the front support wheels, the projection surface has a good group. According to the rotation of the standing reinforcing plate, the left and right sides of the shaft are lit, and the mouth is lit. Feeling when powering.

Easy to colocate, but loaded. The above-mentioned hanger arm of the present invention is provided with the aforementioned hanger arm. Therefore, the left and right bearing portions can be pivoted and are usually stable. The left and right sides of the two hanger brackets must be specially formed on the base further enabling the left and right standing height. It can be made into a narrow punch with load 2 characteristics. In addition to the stand of the stand, the protrusions can be used for a short period of time. It can be used to make the two standing supports 3 characteristics. In addition to the standard hanger arms that are connected to the protrusions, they can be spaced. It is integrated to increase the power of the device. It is supported by a pair of standing and standing brackets, and its scales are easy to support. The support wheels are connected by two widths than two axes, which can be burdensome. One standing bracket supports the protruding surface, while the two standing bracket frames support the hub on the first or the first side and the left and right abutment. This reinforcement can be obtained by the support force formed in the power unit by the best effort, which can be integrated into a bracket to support the wheel holding hub. , Can be made, and can make Yiwei 'stand brackets on the left bearing support the stand bracket to improve its riding feeling, because the stand brackets are arranged between the wheels In addition to the features of the stand-support bracket 2 between the hubs, the stand-up support 312 of the board between the feet / Invention Manual (Supplement) / 92-07 / 921〗 2832 13 200307618 The stand-up stopper of the stand position, therefore, The reinforcing plate connecting the protruding surface and the support foot can be turned into a stopper plate that also serves as a standard stand-up stand, and can simplify the structure of the stand stand. In addition, according to the fourth feature of the present invention, in addition to any of the first to third features, the hanger arms on the left and right are formed to be narrow from the bearing portion toward the base portion at an interval between the two in plan view. It is slightly splayed. Therefore, by connecting the left and right hanger arms and pivots, the rigidity in the horizontal direction can be increased. In addition, the left and right standing brackets are formed at the base of the two hanger arms to narrow the gap. , It can make the standing stand lighter and make the standing stand achieve strong support.
