Abstract: The present disclosure relates to a reducer. The reducer includes a casing, an internal ring gear and an elastic cushion. The casing has an inner circumferential wall provided with a first limiting part. The internal ring gear is arranged in the casing and has an outer circumferential wall provided with a second limiting part. The first limiting part is fitted with the second limiting part to limit rotation of the internal ring gear. The elastic cushion has at least a portion located between the second limiting part and the inner circumferential wall of the casing and abutting against the second limiting part and the inner circumferential wall of the casing.

Abstract: A brake device and a winch having the same are provided. The brake device includes a brake sleeve, a torsion spring, a sealing member and a braking assembly. The torsion spring is fitted over the braking assembly, and the brake sleeve is fitted over the torsion spring. The braking assembly is configured to drive the torsion spring to move between an expanded position and a retracted position, so as to lock and release the brake sleeve. The sealing member is arranged between the brake sleeve and the braking assembly, so that a sealing cavity is defined between the brake sleeve and the braking assembly.

Abstract: A vehicle winch includes a motor assembly, a rope drum assembly, and a reducing gear assembly. The rope drum assembly defines a drum cavity extending in an axial direction of the rope drum assembly, and a part of the motor assembly is arranged in the drum cavity. The reducing gear assembly includes a primary planet gear train and a reducing gear train subassembly, the motor assembly, the primary planet gear train and the reducing gear train subassembly are sequentially arranged along the axial direction, the primary planet gear train is arranged in the drum cavity, and the primary planet gear train has an input end coupled to an output end of the motor assembly and an output end coupled to an input end of the reducing gear train subassembly, and the reducing gear train subassembly has an output end coupled to an input end of the rope drum assembly.
