The invention discloses a platform trailer adopting a hydraulic braking mechanism. The platform trailer is characterized in that the platform trailer comprises a traction mechanism, a brake mechanism,a vehicle frame, and a steering mechanism; the traction mechanism comprises a telescopic traction arm, a pull ring assembly and a limiting sleeve; the brake mechanism comprises a brake master cylinder, a brake oil can, a brake lower pump and a disc brake disc; the steering mechanism comprises a steering pull rod, a pivotal bearing, a front wheel rotating shaft and a rear wheel rotating shaft; theplatform trailer is mainly braked and decelerated by a tractor; the telescopic traction arm is loaded with a push force and is driven to move backwards, the pull ring assembly is driven to move backwards, a cylindrical spiral compression spring is compressed, an adjusting rod pushes the brake oil can backwards, and high-pressure oil drives the brake lower pump to work through a brake oil pipe, sothat the disc brake disc acts, brake is conducted, and a set of closed-loop thrust system is formed. Decelerating and braking can be effectively achieved, and vehicle and cargo safety is guaranteed.

    本发明公开了一种采用液压制动机构的平板拖车,其特征在于:它包括牵引机构、制动机构、车架和转向机构,牵引机构包括伸缩式牵引臂、拉环组件和限位套,制动机构包括制动总泵、刹车油壶、刹车下泵和碟刹盘,转向机构包括转向拉杆、回转轴承、前轮转轴和后轮转轴,该平板拖车主要通过牵引车制动减速,给伸缩式牵引臂一个推力并使之向后移,拉环组件随之向后,压缩圆柱螺旋压缩弹簧,调整杆向后推压刹车油壶,高压油经刹车油管驱动刹车下泵工作,使碟刹盘动作,进而刹车制动,形成一套闭环推力系统。可以有效减速制动,保证车辆及货物安全。
