The invention relates to a transmission brake integrated device for a vehicle, and belongs to the technical field of vehicles. The device comprises a brake positioned in a rim, and a speed reducer, wherein one side of the rim is provided with an open end disk which is fixedly connected with an output flange; friction plates which are distributed at intervals are arranged at one end of the brake close to the end disk; brake discs are arranged between adjacent friction plates; an oil cylinder block is arranged on one side of a friction pair constructed by the friction plates and the brake discs; a travel braking oil cylinder and a parking braking oil cylinder are arranged in the oil cylinder block; a travel piston and a parking piston are arranged in the travel braking oil cylinder and the parking braking oil cylinder respectively; parking springs containing a return mechanism are distributed at intervals along the outer circumference of the parking piston; the speed reducer extends into a cavity in the middle part of the oil cylinder from the open end of the rim; an output shaft on the middle part of the speed reducer is fixedly connected with an output flange; a shell and a brake shell are fixedly connected with a frame. On the premise of ensuring the original functions, the structure can be as compact as possible, and the research and development demands of novel vehicles with narrow structural spaces can be met practically.
