In order to achieve the above object, the utility model adopts the following technical solutions:

An improved front wheel assembly of a stroller, comprising a front hub assembly, a front hub bracket, and a front hub connecting bracket, a front hub assembly is arranged between the front hub bracket and the front hub connecting bracket, and the front hub assembly It consists of a front wheel hub, a front fork frame, and a fixed frame. The fixed frame is arranged in the middle of the front wheel hub bracket. The bottom of the fixed frame is fastened with a front fork frame. A positioning device is arranged inside, and a shock absorbing device is arranged on the upper part of the front fork.

Wherein, the positioning device includes a lower positioning rotary block and an upper positioning rotary block, the outer sleeve sleeve is connected after the transition between the lower positioning rotary block and the upper positioning rotary block, and the top of the upper positioning rotary block is provided with a vertical positioning Spring, lateral positioning spring, one end of the lateral positioning spring is provided with a limit block.

Wherein, the shock absorbing device includes a front fork lower plate and a front fork upper plate, the front fork lower plate is hinged with the front fork upper at an angle, and the front fork lower plate and the front fork upper plate A shock absorbing spring is provided, the bottom of the shock absorbing spring is fastened to the upper inner wall of the lower plate of the front fork frame, and the upper part of the shock absorbing spring is pushed against the inner wall of the upper plate of the front fork frame, and the angle of the shock absorbing spring is 90°.

Beneficial effects of the utility model: the utility model includes a front hub assembly, a front hub bracket, and a front hub connecting bracket, and a front hub assembly is arranged between the front hub bracket and the front hub connecting bracket, and the front hub assembly includes The front wheel hub, the front fork frame, and the fixed frame, the fixed frame is arranged in the middle part of the front wheel hub bracket, the front fork frame is buckled on the bottom of the fixed frame, the front wheel hub is connected to the bottom shaft of the front fork frame, and the fixed frame is internally arranged There is a positioning device, and the upper part of the front fork frame is provided with a shock absorbing device. The utility model provides a positioning device and a shock absorbing device in the front wheel hub assembly, thereby ensuring the shock absorbing effect and positioning effect of the baby carriage, and improving the driving performance of the baby carriage. stability and flexibility when turning.
