The invention discloses a front suspension form of a four-wheel scooter, which relates to the technical field of scooters and comprises a suspension device, two ends of the upper part of the suspension device are fixedly connected with a scooter frame, and the lower part of the suspension device is connected with a front suspension swing arm; one end of the front dangling arm is connected with a tire, and the other end is hinged with a pull rod; a triangular arm is arranged at one end of the pull rod; the front suspension swing arm is movably connected with the front shock absorber through the pull rod, the end, away from the pull rod, of the front shock absorber is fixedly connected with the vehicle frame, driving force, braking force and lateral force of tires and the ground are transmitted to the vehicle frame, and when a vehicle jumps downwards, the front suspension swing arm rotates anticlockwise relative to the suspension device and can drive the pull rod to move upwards. When the vehicle jumps upwards, a spring and a damping block of the front shock absorber are pulled outwards at the same time (otherwise, when the vehicle jumps upwards), the excitation force from the ground is relieved through the front shock absorber, part of the excitation force transmitted to the vehicle frame is eliminated through the damping block, and therefore vibration of the vehicle frame is reduced, a human body feels more comfortable, and the driving experience is improved.

    本发明公开了一种四轮滑板车前悬架形式,涉及滑板车技术领域,包括悬置装置,悬置装置的上部两端与车架固定连接,悬置装置的下部连接有前悬摆臂;前悬摆臂的一端与轮胎连接,另一端铰接有拉杆;拉杆的一端设有三角臂;前悬摆臂通过拉杆与前减震器活动连接,前减震器远离拉杆的一端与车架固定连接,将轮胎与地面的驱动力和制动力、侧向力传递给车架,当车辆向下跳动时,前悬摆臂相对悬置装置逆时针转动,会带动拉杆向上动,同时向外拉动前减震器的弹簧和阻尼块(当车辆向上跳动时,则反之),通过前减震器减缓来自地面的激力,并通过阻尼块消除部分传递到车架的激力,从而使得车架震动减小,人体感受更舒适,提升了驾驶体验。
