Problems solved by technology

However, because the fixed position of the balance shaft is limited by the structure of the engine, it cannot be arranged in the cylinder block
The existing balance shaft arrangement is usually arranged in a way that occupies the inherent space of other systems, but this arrangement increases the volume of the engine, which is not conducive to the optimization of the space in the vehicle engine compartment

Embodiment Construction

[0030] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementations described here are only used to illustrate and explain the present disclosure, not to limit the present disclosure.

[0031] In this disclosure, unless stated to the contrary, the used orientation words such as "up and down" generally refer to the corresponding up and down directions in the installed state, and "inside and outside" refer to the relative to the contour of the component itself. inside and outside. It should be noted here that the above orientation words are only used to explain and illustrate the present disclosure, and are not used to limit.

[0032] The present disclosure intends to fix the balance shaft in the oil pan to make full use of the space in the oil pan. While arranging the balance shaft structure to balance the vibration of the engine, it does not increase th...

Abstract

The invention relates to a balancing shaft device and an engine. The balancing shaft device (2) is used for being arranged in an oil sump of the engine, and comprises a balancing shaft (21), a plurality pairs of eccentric blocks (22) and an oil and gas stabilizer (23), wherein the multiple pairs of eccentric blocks (22) are arranged on the balancing shaft (21). The oil and gas stabilizer (23) is prepared from a light material, the oil and gas stabilizer (23) and the eccentric blocks (22) are jointly formed into a structure with a rotary outer periphery, and the rotary outer periphery rotates around the axis of the balancing shaft (21). The balancing shaft device is suitable for being arranged in an inner cavity of the oil sump so that the available space of the engine can be sufficiently utilized, and the size of the engine is not enlarged while the damping effect is achieved.

Description

technical field [0001] The present disclosure relates to the field of engines, in particular, to a balance shaft device and an engine. Background technique [0002] In traditional vehicles, due to the limited space in the engine compartment, it is necessary to optimize the space in the engine compartment to maximize the utilization rate. [0003] For a three-cylinder engine, it is usually necessary to increase the balance shaft structure to balance the vibration problem of the engine. However, because the fixed position of the balance shaft is limited by the structure of the engine, it cannot be arranged in the cylinder block. The existing arrangement of balance shafts is usually arranged in a way that occupies the inherent space of other systems, but this arrangement increases the volume of the engine, which is not conducive to the optimization of the space in the vehicle engine compartment. Contents of the invention [0004] The purpose of the present disclosure is to ...
