Specifically, the steering column 132 is provided with a steering handle 1322 by the steering column 132 rotatably coupled to the main bracket 110, so that the steering column 132 is rotated relative to the main bracket 110 by the steering handle 1322. When the steering column 132 is rotated, the steering arm 134 provided to the steering column 132 swings around the steering column 132. The steering arm 134 is connected to the first pull arm 137 and the second pull arm 138 through the steering adjustment member 136, and when the steering arm 134 swings, the first pull arm 137 and the second pull arm 138 are driven to deflect, so that the front wheels 112 on both sides of the main frame 110 synchronously move and change direction along with the swing of the steering arm 134.

Specifically, the first pull arm 137 can adjust the length of the first adjusting pull rod 1374 through the first connecting arm 1372 and the first adjusting pull rod 1374 which are connected with each other in the assembling process, so as to adjust the length of the whole first pull arm 137, and facilitate adjusting the toe-in of the front wheel 112, thereby realizing adjustment of the assembling tolerance. Similarly, the second arm 138 is connected to the second connecting arm 1382 and the second adjusting link 1384, so that the length of the second adjusting link 1384 can be adjusted during the assembling process, thereby adjusting the length of the whole second arm 138, and facilitating the adjustment of the toe-in of the front wheel 112, so as to adjust the assembling tolerance.

As shown in fig. 5 and 6, the first and second adjusting tie rods 1374 and 1384 are connected to the knuckle 160 through the ball head assembly 139, respectively, at an eccentric position of the knuckle 160. By adopting the above mode, the steering knuckle 160 is favorably ensured to be reliably connected with the first adjusting pull rod 1374 and the second adjusting pull rod 1384 respectively, so that the locking is avoided, and the connection stability is favorably ensured. In addition, the connection is arranged at the eccentric position of the steering knuckle 160, so that more labor is saved in the steering process.

The locking mechanism 140 may take a disc brake-like form to simultaneously lock the first and second locking tabs 176, 178. When the swing arm 170 is not required to be fixed relative to the main support 110, the locking mechanism 140 operates to lock the first and second locking pieces 176 and 178. When it is desired to rotate the swing arm 170 relative to the main support 110, the locking mechanism 140 releases the locking action of the first and second locking pieces 176 and 178.

As shown in fig. 1 and 7, the damper mechanism 120 includes a first damper 122 and a second damper 124 that are disposed opposite to each other, the first damper 122 being connected to the first connecting portion 172 and the left lower rocker arm 1542, respectively, and the second damper 124 being connected to the second connecting portion 174 and the right lower rocker arm 1544, respectively.

Specifically, when the first damper 122 is connected to the first connecting portion 172 and the left lower rocker arm 1542, the first damper 122 passes through the left upper rocker arm 1522 and forms a desired connection relationship with the left lower rocker arm 1542, wherein the first damper 122 can be connected to the reinforcing arm 156 on the left lower rocker arm 1542, and the reinforcing arm 156 can be provided with a connecting lug plate for facilitating connection. It will be appreciated that the first damper 122 has a certain relative movement with the first connecting portion 172 and the left lower rocker arm 1542, and in order to ensure the stability of the connection, the two ends of the first damper 122 are rotatably connected with the first connecting portion 172 and the left lower rocker arm 1542, respectively. Similarly, when the second damper 124 is connected to the second connecting portion 174 and the right lower rocker arm 1544, the second damper 124 passes through the right upper rocker arm 1524 to form a desired connection with the right lower rocker arm 1544, wherein the second damper 124 can be connected to the reinforcing arm 156 of the right lower rocker arm 1544, and the reinforcing arm 156 can be provided with a connecting lug for facilitating the connection. To ensure the stability of the connection, both ends of the second damper 124 are rotatably connected to the second connecting portion 174 and the right lower rocker arm 1544, respectively. The first damper 122 and the second damper 124 may be in the form of compression springs disposed on the telescopic rod, so as to ensure the connection stability and play a role in damping and buffering the impact force.

As shown in fig. 8, the knuckle 160 is connected to the front wheel 112 through a hub assembly 180, the hub assembly 180 includes a hub 182, a mounting plate 184 and a rotating shaft 186, the rotating shaft 186 is rotatably connected to the knuckle 160, the mounting plate 184 and the hub 182 are respectively sleeved on the rotating shaft 186, the hub 182 and the mounting plate 184 are relatively fixed, and a fastening member 187 is disposed at one end of the rotating shaft 186, to which the hub 182 is connected, so that the hub 182 and the rotating shaft 186 are fixedly connected; the steering knuckle 160 is further provided with a disc brake caliper 164, and the mounting disc 184 is provided with a disc brake disc 188 which is matched with the disc brake caliper 164 to brake or brake the front wheel 112.

Specifically, the rotating shaft 186 is rotatably connected to the knuckle 160, the mounting plate 184 and the hub 182 are respectively sleeved on the rotating shaft 186, the hub 182 and the mounting plate 184 are relatively fixed, and when the fastening member 187 disposed at the end of the rotating shaft 186 connected to the hub 182 abuts against the hub 182, the hub 182 is fixed relative to the rotating shaft 186. In this way, the hub 182 and the mounting plate 184 are fixed relative to the shaft 186 so as to rotate synchronously with the shaft 186. A bearing may be disposed between the rotating shaft 186 and the knuckle 160 to make the rotation between the rotating shaft 186 and the knuckle 160 smoother. The mounting plate 184 may be provided with a positioning pin to fix the mounting plate 184 and the hub 182 relatively, and the mounting plate 184 is provided with a disc brake 188 engaged with the disc brake caliper 164, so that the disc brake 188 rotates synchronously with the hub 182. When the disc brake caliper 164 provided on the knuckle 160 is actuated, the disc brake 188 is clamped, so that the disc brake 188 receives a rotational resistance, which is transmitted to the hub 182, thereby braking the front wheel 112, and when the disc brake caliper 164 is not actuated, the front wheel 112 is braked by contact with the front wheel 112, so that the front wheel 112 can normally rotate.
