However, the arrangement of the BSG gear train is not considered when the prior gear train is designed and developed, the BSG gear train is worse than the traditional gear train in use working condition, the requirement on the arrangement space of the front end is larger, and the space which can be exerted on the gear train arrangement is smaller under the condition that the original parts of the engine are not changed.
The existing 48V BSG wheel train is divided into a single-layer wheel train design and a double-layer wheel train design, the single-layer BSG wheel train is generally transformed on the basis of the existing engine non-BSG wheel train, the universality of other parts of the wheel train and the non-BSG wheel train can be considered on the basis of not changing the existing engine parts, and meanwhile, the problem that the axial size of the engine brought by the double-layer wheel train design is increased can be avoided. However, because of the limitation of the layout space, the wrap angle of the conventional single-layer BSG gear train is generally controlled to be smaller, the wrap angle of a tension pulley is generally about 60-70 degrees, and the compensation capability of the tension pulley on the length change of the belt is not high, so that the initial design tension of the belt is higher, the service life of a gear train bearing and the service life of the belt are not favorable, and the friction work of the gear train is not reduced. Meanwhile, under the extreme working conditions of BSG (basic starter generator) such as low-temperature environment and insufficient battery power of 48V, when the engine needs to be started by a 12V starter, the two-way tensioner is easy to collide with a limit stop to generate abnormal sound due to an excessively small wrap angle.
Disclosure of Invention
In view of the above, the present invention provides an accessory gear train of a BSG hybrid engine, which increases a tensioner wrap angle by adjusting a gear train layout.
The invention provides an accessory wheel train of a BSG (Belt-driven generator) hybrid engine, which comprises a poly V-belt, a BSG motor, a two-way tensioner, a first idle wheel, a water pump, an air-conditioning compressor, a crankshaft and a second idle wheel, wherein the two-way tensioner is arranged on the BSG motor, a motor belt pulley is arranged on the BSG motor, a water pump belt pulley is arranged on the water pump, an air-conditioning compressor belt pulley is arranged on the air-conditioning compressor, a crankshaft belt pulley is arranged on the crankshaft, the poly V-belt sequentially bypasses the motor belt pulley, the first idle wheel, the water pump belt pulley, the air-conditioning compressor belt pulley, the crankshaft belt pulley and the second idle wheel to form a closed loop belt, and the first idle wheel is arranged on the inner side of the poly V-belt.
According to one embodiment of the invention, the bidirectional tensioner comprises two tension pulleys, the two tension pulleys are respectively pressed on the outer edge of the motor pulley, and the part of the V-ribbed belt entering and leaving the motor pulley is pressed between the tension pulleys and the motor pulley.
According to one embodiment of the invention, the water pump pulley is arranged on the outer side of the V-ribbed belt.
According to one embodiment of the present invention, the motor pulley, the air conditioner compressor pulley, and the crank pulley are disposed inside the v-ribbed belt.
According to one embodiment of the invention, the second idler pulley is pressed against the outer side of the v-ribbed belt.
According to one embodiment of the invention, the second idler pulley is located between the crankshaft pulley and the motor pulley.
According to one embodiment of the present invention, a center line connecting the motor pulley, the air conditioner compressor pulley, and the crank pulley forms a triangle.
According to an embodiment of the present invention, the axis of the water pump pulley is located inside a line connecting the axis of the air conditioner compressor pulley and the axis of the motor pulley, and the axis of the first idle pulley is located outside a line connecting the axis of the air conditioner compressor pulley and the axis of the motor pulley.
According to the accessory wheel train of the BSG hybrid power engine, the wheel train layout is adjusted, so that the idler wheel close to one side of the bidirectional tensioner expands the wrap angle of the tension wheel, the compensation capacity of the tension wheel on the length change of a belt is improved, the initial design tension of the belt is reduced, the service lives of a wheel train bearing and the belt are prolonged, and the friction work of the wheel train is reduced; meanwhile, the wrap angle of the two-way tensioner is increased, the swing amplitude of the two-way tensioner is reduced when the tension of a belt is compensated, and the problem that when an engine needs to be started by a 12V starter under the extreme BSG working condition such as a low-temperature environment and the electricity of a 48V battery is insufficient, the abnormal sound is generated because the wrap angle of a tension pulley is too small, the swing amplitude of the two-way tensioner is too large and easily collides with a limit stop block is solved.
