The invention relates to the technical field of braking devices, in particular to an auxiliary braking system applied to a sightseeing mini train, which comprises a base and wheels, the main braking unit is vertically arranged above the wheels, the main braking unit is hydraulically driven, the lower portion of the main braking unit can move in the height direction of the base, the main braking unit has a first braking mode and a second braking mode, in the first braking mode, the main braking unit continuously brakes the wheels, and in the second braking mode, the main braking unit continuously brakes the wheels. The main brake unit brakes the wheels intermittently; the auxiliary braking unit is arranged on the peripheral wall of the wheel, a braking part of the auxiliary braking unit is slidably arranged on the wheel in the radial direction of the wheel and can extend out of the peripheral wall of the wheel, the auxiliary braking unit is driven by hydraulic pressure, and the main braking unit activates the auxiliary braking unit in the second braking mode. The situation that the wheels are locked on the rail due to emergency braking is avoided, and the service life of the wheels and the rail is prolonged.
本发明涉及制动装置技术领域,具体是涉及一种应用于观光小火车的辅助制动系统,包括基座和轮子;主制动单元竖直设置在轮子的上方,主制动单元采用液压驱动,主制动单元的下部能沿基座的高度方向移动,主制动单元具有第一制动模式和第二制动模式,第一制动模式下,主制动单元持续对轮子进行制动,第二制动模式下,主制动单元间歇性对轮子进行制动;辅助制动单元设置在轮子的周壁上,辅助制动单元的制动部沿轮子的径向方向滑动设置在轮子上且能从轮子周壁处伸出,辅助制动单元由液压驱动,主制动单元在第二制动模式时将辅助制动单元激活。本发明避免了由于紧急制动轮子在轨道上出现抱死的情况,延长了轮子和轨道的使用寿命。
