The invention provides a split-type timing sprocket shell for a plug-in hybrid electric vehicle detachable suspension bracket. A suspension bracket body is arranged on a sprocket shell body, and the sprocket shell body and the suspension bracket body are fixed by a suspension bracket bolt, and a front oil seal is arranged in a crankshaft extension hole in the lower part of the sprocket shell body;two electromagnet mounting holes are formed in the upper part of the sprocket shell body and are symmetrically distributed, and the hole diameters of the two electromagnet mounting holes are the same; two electromagnet bolt holes are formed in the periphery of each electromagnet mounting hole, and the centers of the two electromagnet bolt holes and the centers of the electromagnet mounting holesare on a straight line; and the crankshaft extension hole is formed in the lower part of the sprocket shell body, and the front oil seal for oil sealing of the front end of a crankshaft is arranged inthe crankshaft extension hole in a press-fitting mode through interference fit. According to the split-type timing sprocket shell for the plug-in hybrid electric vehicle detachable suspension bracket, the production cost is saved, the production cycle is shortened, the production efficiency is improved, the split-type timing sprocket shell is convenient and fast, the test efficiency and the testeffect are improved, a cylinder head cover and an oil pan are sealed well, and the split-type timing sprocket shell is applied in the technical field of vehicle engines.
