Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0022] like figure 1 , figure 2 As shown, the present invention is constructed by parts such as connecting rod 1, connecting rod cover 3, first connecting rod bolt 4, second connecting rod bolt 4', upper bearing bush 6 and lower bearing bush 7. Wherein, the connecting rod 1 is formed by forging aluminum alloy. The small lower end of connecting rod 1 upper end is big, offers piston pin hole 2 at the small head of connecting rod 1, and this piston pin hole 2 is used for piercing piston pin, and connecting rod is connected with piston. There is an annular oil collecting groove 18 at the middle part of the inner wall of the piston pin hole 2, and an upper lubricating hole 19 is opened at the top of the small end of the connecting rod 1 . The upper port of the upper lubricating hole 19 is located on the top surface of the small head of the connecting rod 1 , a...

Abstract

The invention discloses a connecting rod assembly for a high rotation speed petrol engine. An upper oil collection groove (9) is arranged in the inner wall of a first arc-shaped groove of a large head of a connecting rod (1), and a first oil inlet (10) is arranged in an upper beating metal (6) and penetrates through the inner surface and the outer surface of the upper beating metal (6). A lower oil collection groove (11) is arranged in the inner wall of a second arc-shaped groove of a connecting rod cover (3), and a second oil inlet (12) is arranged in a lower beating metal (7) and penetrates through the inner surface and the outer surface of the lower beating metal (7). The lower oil collection groove (11) is communicated with an oil inlet groove (14) arranged on the top face of an oil shed block (8) through an oil duct (13). Under the condition that performance and lubricating methods of a petrol engine are not changed, a one-way lubrication oil-taking method is changed into a two-way oil-taking method, and therefore a connecting rod assembly lubrication problem of the high rotation speed petrol engine is solved thoroughly, and quantized design demands of engines are met at the same time.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a connecting rod assembly of a high-speed gasoline engine. Background technique [0002] The connecting rod assembly is an important part of the engine crank linkage mechanism. It is generally composed of connecting rods, connecting rod covers, connecting rod bolts and bearing bushes. The small end of the connecting rod is connected to the piston pin, and the large end of the connecting rod is connected The connecting rod bolt is fixed, and a crank pin hole is formed between the big end of the connecting rod and the connecting rod cover, which is used to connect with the crank pin, and a bearing bush is arranged in the mounting hole, and the bearing bush is selected according to the size of the engine. The function of the connecting rod assembly is to transmit the force received by the piston to the crankshaft, so that the reciprocating motion of the piston is convert...
