The invention discloses a brake integrating parking braking and service braking functions. The brake comprises a box body, a transmission shaft, a belleville spring, a service braking piston, a parking braking piston, a first pressing disc, a second pressing disc, a plurality of outer friction plates and a plurality of inner friction plates; the box body comprises a front end cover, a shell and arear end cover; a first mounting hole and a second mounting hole are formed in the side wall of the shell; pressure oil conveying assemblies are mounted on the first mounting hole and the second mounting hole correspondingly; pressure oil channels are formed in the pressure oil conveying assemblies; one pressure oil passage is communicated with the first mounting hole to form a parking brake release pressure oil passage; and the other pressure oil passage is communicated with the second mounting hole to form a service brake pressure oil passage. According to the technical scheme, the parking brake release pressure oil passage and the service brake pressure oil passage are both arranged on the side wall of the shell, so that the manufacturing difficulty and the assembly precision of the shell and the end cover are effectively reduced.

    本发明公开了一种集成驻车制动和行车制动功能的制动器,包括箱体、传动轴、蝶形弹簧、行车制动活塞、驻车制动活塞、第一压盘、第二压盘、若干外摩擦片和若干内摩擦片;所述箱体包括前端盖、壳体和后端盖,所述壳体的侧壁上设有第一安装孔和第二安装孔,所述第一安装孔和第二安装孔上均安装有压力油输送组件,所述压力油输送组件内设有压力油道,一压力油道连通第一安装孔以形成驻车制动释放压力油道,另一压力油道连通第二安装孔以形成行车制动压力油道;本技术方案将驻车制动释放压力油道和行车制动压力油道均设置在壳体侧壁上,从而有效的降低了壳体与端盖的制造难度以及装配精度。
