Specifically, a first fixing shaft 209 is fixedly installed in a first avoidance hole 5 formed in the mounting frame 1, and a second fixing shaft 210 is fixedly installed in a second avoidance hole 6. First ends of the two first cantilevers 202 are rotatably connected to the first fixed shaft 209, and first ends of the two second cantilevers 204 are rotatably connected to the second fixed shaft 210. Two second cantilevers 204 are fixedly provided with damping connecting pieces 208, two ends of a damper 201 are respectively connected with the two damping connecting pieces 208, and the damper 201 is positioned in the third avoiding hole 7.

The connecting piece 3012 is fixedly mounted on the first cantilever 202 positioned at the left side, the brake block 3011 is arc-shaped, the arc center of the brake block 3011 is positioned at the swinging center of the first cantilever 202 around the mounting frame 1, so that the first cantilever 202 and the brake block 3011 swing around the same center, and the locking clamp body 303 is fixedly mounted on the mounting frame 1 through the fixing assembly 305. The locking pliers body 303 is in an inverted U shape, and the locking baffle 304 is fixedly connected to the inner side of the locking pliers body 303.

The steering mechanism 4 drives the two steering knuckles 205 to synchronously deflect through the steering mechanism 4.

Through adopting above-mentioned technical scheme, during the use, steering mechanism 4 drives two knuckle 205 and deflects in step to drive two front wheels deflection, the convenience turns. When braking, steering or bumping on the road, the swing speed of the first cantilever 202 is limited by the locking mechanism 3, so that the deflection of the deflection mechanism 2 is limited, the vehicle body is stabilized, and the inverted tricycle is prevented from turning on one's side. In addition, when the inverted tricycle is parked, the first cantilever 202 can be limited to swing through the locking mechanism 3, so that the deflection of the deflection mechanism 2 is limited, and the inverted tricycle is prevented from tilting sideways when parked. Because the locking mechanism 3 controls the swing of the first cantilever 202, the locking pump 306 drives one friction plate 307 to approach the other friction plate 307 to clamp the brake plate 3011, so that the brake plate 3011 can be subjected to continuous and stable resistance, the locking mechanism 3 can stably limit the swing of the first cantilever 202, the stability of the inverted tricycle in riding is further ensured, and the effect of preventing rollover is achieved.

3-5, In order to enhance the stability of the connection between the first cantilever 202 and the connecting piece 3012, further, on the basis of the above technical solution, the first cantilever 202 is provided with a positioning protrusion 203 and a first mounting hole, and the positioning protrusion 203 is a strip-shaped protrusion; the connecting piece 3012 is provided with a second mounting hole 3013 and a positioning hole 3014, and the positioning protrusion 203 is clamped in the positioning hole 3014. Preferably, the second mounting holes 3013 are arranged at intervals, and are sequentially arranged at the left end part, the middle part and the right end part of the connecting sheet 3012, and the first mounting holes and the second mounting holes 3013 are correspondingly arranged. The connecting piece 3012 is connected to the first cantilever 202 by a first mounting bolt 302, and a threaded section of the first mounting bolt 302 passes through the second mounting hole 3013 and is then threaded into the first mounting hole. Since the connection piece 3012 and the first suspension arm 202 are connected together by the three first mounting bolts 302 and the positioning protrusions 203 are engaged with the positioning holes 3014, the ability of the connection piece 3012 to resist deformation in the swinging direction of the first suspension arm 202 is enhanced, and thus the stability of the connection between the first suspension arm 202 and the connection piece 3012 is enhanced.

Due to the fact that the steering joint 4032 is added between the steering rocker 4031 and the swing arm 402, the installation position of the steering column on the frame can be properly adjusted, the steering column 401 and the swing arm 402 are beneficial to avoiding the internal structure of the frame, and the frame can be more flexible in structure.

Since the second rotating portion 406 is rotatably coupled to the inner side of the first connecting fork 4072 by the second rotating shaft 4076, the connecting joint 404 is not easily separated from the first connecting fork 4072, thereby enhancing the stability between the connecting joint 404 and the first connecting arm 407.

With continued reference to fig. 12, based on the above technical solution, further, the second connecting arm 408 includes an adjusting shaft 4081 and a second connecting sleeve 4082; one end of an adjusting shaft 4081 is arranged in the first connecting sleeve 4073 in a penetrating way, the adjusting shaft 4081 is in rotary connection with the first connecting sleeve 4073, specifically, one end of the adjusting shaft 4081 is arranged in the third bearing 4074 and is in rotary connection with the first connecting sleeve 4073 through the third bearing 4074; the other end of the adjusting shaft 4081 is arranged in the second connecting sleeve 4082 in a penetrating way, and the adjusting shaft 4081 is in threaded connection with the second connecting sleeve 4082; one end of the second connecting sleeve 4082, which is far away from the adjusting shaft 4081, is fixedly connected with a second connecting fork 4083, a third rotating shaft 4084 is arranged on the inner side of the second connecting fork 4083, and the third rotating shaft 4084 is rotationally connected with the steering head 409. In order to prevent the relative rotation of the adjustment shaft 4081 and the second connection sleeve 4082, a situation occurs in which the adjustment shaft 4081 is disengaged from the second connection sleeve 4082. Preferably, the adjusting shaft 4081 is screwed with a stop nut 4085, and the second connecting sleeve 4082 is abutted by the stop nut 4085.

By adopting the above technical scheme, because of the threaded connection between the second connecting sleeve 4082 and the adjusting shaft 4081, the length of the second connecting arm 408 can be adjusted by rotating the adjusting shaft 4081, thereby compensating for part processing errors, assembly errors and adjusting the toe-in. The first connecting sleeve 4073 and the adjusting shaft 4081 are rotationally connected to facilitate the rotation of the rotation shaft, and meanwhile, the front wheel and the first connecting arm 407 can relatively rotate when steering, so that the front wheel is more flexible when steering, and the front wheel is prevented from being blocked.

In order to facilitate screwing the adjusting shaft 4081 when adjusting the length of the second connecting arm 408, it is preferable that a hexagonal head 4086 is fixedly connected to the adjusting shaft 4081, and the hexagonal head 4086 is located between the retaining nut 4085 and the first connecting sleeve 4073. When the length of the second connecting arm 408 is adjusted, the hexagonal head 4086 is screwed by a tool such as a wrench, so that the adjusting shaft 4081 is screwed, a stable acting point is provided for the wrench tool, and the length of the second connecting arm 408 is convenient to adjust.

The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
