The invention relates to the technical field of special vehicles, and discloses a semitrailer suspension structure which comprises a frame, a first axle and a second axle, the first axle is provided with a first friction wheel, the frame is hinged to a turnover frame, the turnover frame is provided with a rotatable second friction wheel and a rotatable third friction wheel, and the second friction wheel is provided with a second friction wheel. The first friction wheel, the second friction wheel and the third friction wheel abut against each other in sequence, the frame is hinged to a first hydraulic cylinder, a piston rod of the first hydraulic cylinder is hinged to the turnover frame, and the second axle is provided with a fourth friction wheel. Compared with the prior art, the invention has the following advantages and effects: the inertia of the rotating first axle is originally selected and utilized, the braking friction force is applied to the second axle, the second axle is braked and stopped, meanwhile, the speed reduction of the first axle is also realized, the auxiliary braking effect is achieved, and the brake can be started when the original brake fails or fails or breaks down and is emergently braked; and the driving safety is effectively ensured.

    本发明涉及专用车技术领域,公开了一种半挂车悬架结构,包括车架、第一车轴、第二车轴,所述第一车轴设有有第一摩擦轮,所述车架铰接有翻转架,所述翻转架设有可转动的第二摩擦轮、第三摩擦轮,所述第一摩擦轮、所述第二摩擦轮、所述第三摩擦轮依次抵紧,所述车架铰接有第一液压缸,所述第一液压缸活塞杆与所述翻转架相铰接,所述第二车轴设有第四摩擦轮。本发明具有以下优点和效果:本发明独创性地选择利用旋转的第一车轴的惯性,对第二车轴施加制动摩擦力,对第二车轴进行制动、刹停,同时也对第一车轴实现降速,起到辅助刹车作用,在原刹车失效或失灵、故障以及紧急制动时可以启动,有效保证行车安全。
