Embodiment 1

[0064] For the above issues, see Figure 3-Figure 6 As shown, this embodiment provides a timing link assembly, including a shaft 3, a timing link 4 and a gear part 7, and the gear part 7 is used to drive the camshaft through gear meshing, wherein: the shaft 3 The first end of the shaft is fixedly connected with the fixed connecting rod assembly 2 or the shaft 3 is integrally formed with the fixed connecting rod; for in-line engines, see figure 2 As shown, the fixed connecting rod assembly 2 in the in-line engine adopts the above structure; the specific shaft rod 3 is fixedly connected with the first connecting rod 1' or the second connecting rod 2', and the shaft rod 3 is perpendicular to the first connecting rod. 1' or second link 2' set. The first end of the timing connecting rod 4 is rotatably connected with the second end of the shaft rod 3 (for example, the two are connected by a bearing), and the second end is connected with the gear part 7 in a driving manner; the sha...

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 transmission 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 with the second fixed connecting rod assembly, and the second fixed connecting rod assembly is connected with The shaft rod 3 is fixedly connected. The horizontally opposed engine in this embodiment uses the timing connecting rod assembly in the first embodiment, so the second fixed connecting rod assembly, the shaft 3 and the timing connecting rod assembly can also be synchronized in motion, thereby making the piston The reciprocating motion of the camshaft works in synchronization with the opening and...

Embodiment 4

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

[0084] Taking a four-stroke four-cylinder engine as an example (the principle of an even-numbered cylinder 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 bidirectional transmission gear 70, wherein: the two ends of the connecting rod group A50 are respectively fixedly connected with a piston A10 and a piston B20, Both ends of the connecting rod group B60 are respectively fixed with a piston C30 and a piston D40 (wherein, A, B, C, and D...

Abstract

The invention provides a timing connecting rod assembly and a horizontally opposed engine, which solves the problem that the reciprocating motion of the piston and the opening and closing of the intake valve and the exhaust valve controlled by the camshaft cannot work in synchronization. The timing connecting rod assembly includes a shaft rod, a timing connecting rod and a gear part, the gear part is used for gear meshing transmission with the camshaft, and the first end of the shaft rod is fixedly connected with the fixed connecting rod assembly; One end is rotatably connected with the second end of the shaft rod, and the second end is connected with the gear part; when the shaft rod reciprocates linearly with the fixed connecting rod assembly, it can drive the second end of the timing connecting rod to make a circular motion, and then Drive the gear part to rotate. The fixed connecting rod assembly and the shaft move synchronously in a straight line. When the piston stops moving, it is convenient for the shaft to stop moving in time, so as to prevent the centrifugal force from generating large inertia in the rotating motion and causing the movement to be out of synchronization, thereby making the reciprocating motion of the piston and the camshaft control progress. The opening and closing of the valve and exhaust valve work in synchrony.

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 piston group, connecting rod group, crankshaft, flywheel group and other components. The reciprocating motion of the piston is transformed into the rotational 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 group 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 rotational movement of the crankshaft drives the camshaft to rotate through the timing belt or timing ...
