Embodiment 1

[0064] For the above problems, see Figure 3-Figure 6 As shown, a timing link assembly is provided in this embodiment, including a shaft 3, a timing link 4 and a gear part 7, and the gear part 7 is used for transmission with the camshaft through gear engagement, wherein: the shaft 3 The first end of the fixed connecting rod assembly 2 is fixedly connected or the shaft rod 3 is integrally formed with the fixed connecting rod; for an in-line engine, see figure 2 As shown, the fixed connecting rod assembly 2 in the in-line engine adopts the above-mentioned structure; the specific shaft 3 is fixedly connected with the first connecting rod 1' or the second connecting rod 2', and the shaft 3 is perpendicular to the above-mentioned first connecting rod 1' or second link 2' setting. The first end of the timing link 4 is rotationally connected to the second end of the shaft 3 (for example, the two are connected by a bearing), and the second end is connected to the gear part 7 in tran...

Embodiment 3

[0081] The difference between this embodiment and the above-mentioned second embodiment is that in the second embodiment the pistons are located on the same side of the output shaft, and in this embodiment the pistons are distributed on both sides of the output drive shaft 90 . A horizontally opposed engine in this embodiment includes a piston, a second fixed connecting rod assembly and the above-mentioned timing connecting rod assembly, the piston is fixedly connected to the second fixed connecting rod assembly, and the second fixed connecting rod assembly is connected to the The shaft rod 3 is fixedly connected. Because the horizontally opposed engine in this embodiment adopts the timing connecting rod assembly in Embodiment 1, it can also make the second fixed connecting rod assembly, the shaft rod 3 and the timing connecting rod assembly move synchronously, and then make the piston The reciprocating motion of the camshaft works synchronously with the opening and closing of...

Embodiment 4

[0083] Since the arrangement of the piston in this embodiment is different from that in the second embodiment, the first fixed connecting rod assembly in the second embodiment (such as figure 2 The structure shown in ) is no longer suitable for this embodiment, so another second fixed connecting rod assembly suitable for horizontally opposed engines is provided in this embodiment.

[0084] Take the four-stroke four-cylinder engine as an example (the principle of the engine with even-numbered cylinders such as six-cylinder and eight-cylinder is the same), such as Figure 7-Figure 13 As shown, the second fixed connecting rod assembly in this embodiment includes a connecting rod group A50, a connecting rod group B60 and a two-way transmission gear 70, wherein: both ends of the connecting rod group A50 are fixedly connected with a piston A10 and a piston B20, Both ends of the connecting rod group B60 are fixed with piston C30 and piston D40 (wherein, A, B, C, D are arranged accor...

Abstract

The invention provides a timing connecting rod assembly and a horizontally opposed engine. The problem that reciprocating motion of a piston and opening and closing of an intake valve and an exhaust valve controlled by a cam shaft cannot be synchronously matched for work is solved. The timing connecting rod assembly comprises a shaft rod, a timing connecting rod and a gear part, wherein the gear part is used for being in meshing transmission with the cam shaft through a gear, and the first end of the shaft rod is fixedly connected with the fixed connecting rod assembly; the first end of the timing connecting rod is rotatably connected with the second end of the shaft rod, and the second end is in transmission connection with the gear part; and when the shaft rod does reciprocating rectilinear motion along with the fixed connecting rod assembly, the shaft rod can drive the second end of the timing connecting rod to do circular motion so as to further drive the gear part to rotate. The fixed connecting rod assembly and the shaft rod synchronously and linearly move, the shaft rod can conveniently stop moving in time when the piston stops moving, asynchronous movement caused by large inertia generated by centrifugal force in rotary movement is prevented, and then reciprocating movement of the piston and opening and closing of an intake valve and an exhaust valve controlled by a cam shaft are synchronously matched for work.

Description

technical field [0001] The invention relates to the technical field of engine transmission structures, in particular to a timing connecting rod assembly and a horizontally opposed engine. Background technique [0002] In the existing engine transmission structure, the crank-connecting rod mechanism is the main moving part, which is composed of a piston group, a connecting rod group, a crankshaft, a flywheel group and other parts. The reciprocating motion of the piston is transformed into the rotary motion of the crankshaft through the connecting rod. The connecting rod and the crankshaft are connected in rotation, and the crankshaft drives the rotation of the flywheel at the same time, and then transmits the power to the gearbox and so on. [0003] Usually the other end of the crankshaft is connected to the camshaft through a timing chain or a timing belt. The active rotation of the crankshaft drives the camshaft to rotate through the timing belt or timing chain, and the cam...
