Problems solved by technology

[0004] At present, the transmission devices of the engine to realize the timing system control are: gear timing transmission, chain timing transmission, belt timing transmission and electronic control transmission system. Since the engine gas distribution system is far from the crankshaft, the gear timing transmission The size is too large, the weight is heavy, and the manufacturing cost is high. It is gradually replaced by the chain timing drive and the belt timing drive. However, the chain timing drive and the belt timing drive are noisy and have a short service life.
Due to the complex structure and high cost of the electronic control transmission system, it has not been widely used.

Embodiment 1

[0063] This embodiment is a timing drive system, such as figure 1 and figure 2 As shown, the timing transmission system includes a bevel gear set 100 , through which the engine crankshaft can be simultaneously drive-connected with the intake camshaft 142 and the exhaust camshaft 152 . It should be noted that the bevel gear set 100 has a variety of structural forms or components. The difference between the bevel gear set 100 and the existing timing transmission system is that the bevel gear set 100 has the ability of long-distance transmission and can have the same lifespan as the engine. That is, by adjusting the length of the transmission shaft in the bevel gear set 100, the long-distance free power transmission between the engine crankshaft and the intake camshaft 142 and the exhaust camshaft 152 can be realized, avoiding the problem of large size of the traditional gear timing transmission system, The structure is compact and the weight is light; the problems of easy wear...

Embodiment 2

[0073] This embodiment is an engine, such as figure 1 and figure 2 As shown, this embodiment includes the timing transmission system described in the above embodiments, and the same parts thereof will not be repeated here.

[0074] Specifically, the engine further includes: a casing and an engine main body installed inside the casing. The engine main body is the power part of the engine, and has engine cylinders, a crankshaft, an intake camshaft 142 and an exhaust camshaft 152 .

[0075] Further, wherein, the crankshaft is connected to the engine output shaft 111, the intake camshaft 142 is equipped with an intake camshaft column gear 141, and the exhaust camshaft 152 is equipped with an exhaust camshaft column gear 151 . Furthermore, the problem of large size of the traditional gear timing transmission system is avoided, and the structure is compact and light in weight; the problems of easy wear of the belt and high cost of use in the belt timing transmission are avoided....

Embodiment 3

[0077] This embodiment is an engine, such as image 3 and Figure 4 As shown, this embodiment adds forward and reverse functions on the basis of the engine proposed in Embodiment 2, and the same parts will not be repeated here.

[0078] Specifically, between the crankshaft and the intake camshaft 142 and the exhaust camshaft 152, a forward and reverse bevel gear set and a forward and reverse switch are arranged; the crankshaft is provided with a crankshaft centering adjustment device 113 , for realizing the centering of the crankshaft, so that the piston of the engine cylinder is at the top dead center or the bottom dead center.

[0079] Further preferably, as Figure 9 As shown, the centering adjustment device includes a centering mark sensor 114 and a centering controller 115 . Wherein, the centering mark sensor 114 is installed on the output shaft 111 of the engine. The centering controller 115 is installed inside the housing, corresponding to the centering mark sensor ...

Abstract

The patent of the present invention discloses a timing transmission system, an engine and a motor vehicle. The timing transmission system includes a bevel gear set, and the crankshaft of the engine can be simultaneously connected to an intake camshaft and an exhaust camshaft through the bevel gear set. The bevel gear set includes: engine output shaft and engine output bevel gear; first drive shaft bevel gear, second drive shaft bevel gear and several drive shafts; intake camshaft spur gear and exhaust camshaft spur gear; transfer shaft, The transfer shaft column gear and the transfer shaft bevel gear, the transfer shaft column gear and the transfer shaft bevel gear are installed at both ends of the transfer shaft, the transfer shaft bevel gear is meshed with the second drive shaft bevel gear, The column gear can mesh with the intake camshaft column gear and the exhaust camshaft column gear at the same time. The invention realizes the purpose of compact structure, light weight and long service life of the device with the timing transmission system by installing a bevel gear set between the engine crankshaft and the intake camshaft and exhaust camshaft.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a timing transmission system, an engine and a motor vehicle. Background technique [0002] At present, the reversing function of the vehicle system is mainly realized through the gearbox or other reversing devices, such as the patent No. CN101224700B "Hybrid Vehicle Transmission System with Mechanical Reversal Function", which also realizes mechanical reversing through the planetary gear transmission outside the engine , and did not realize the engine reverse function. In addition to some vehicles with two-stroke engines, there are only a small number of vehicles that realize the reversing function by reversing the engine, such as the patent No. CN101293476B "Hybrid Power System with Reversing Engine", by installing an electronic controller on the crankshaft to control the camshaft Rotate, and then control the gas distribution valve to realize the engine reverse function. [00...
