The invention discloses an energy absorption brake for an inclined shaft sports car protection device. The brake comprises a friction-type energy absorption component, a spring-type energy absorptioncomponent, an air cooling component and a water cooling component, the air cooling component comprises a heat dissipation fan, and the heat dissipation fan sleeves a first spline shaft; a protection cover is arranged outside the heat dissipation fan, and the protection cover is provided with an air inlet; the water cooling component comprises a heat conduction disk and a cooling disk, the heat conduction disk is arranged on the first spline shaft, and the cooling disk sleeves the heat conduction disk; a water storage cavity is formed in the cooling disk, and the water storage cavity is communicated with a water storage tank through a water inlet pipe and a water outlet pipe. According to the energy absorption brake for the inclined shaft sports car protection device, an inclined shaft sports car is braked through a friction sheet component and a ball lead screw spring component, the kinetic energy of the inclined shaft sports car is converted into friction intrinsic energy among friction sheets and elastic potential energy of springs in the ball lead screw spring component, meanwhile, braking is conducted for the second time through the spring-type energy absorption component, theair cooling component and the water cooling component can absorb the friction intrinsic energy among the friction sheets in time, and the situation is avoided that the braking effect of the friction sheets can be lowered due to the friction intrinsic energy.
