Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] see figure 1 , a starter generator system with a two-stage forward and reverse transmission device includes a starter generator 1, a planetary carrier 2, a planetary gear 3, an inner ring gear 4, a sun gear 5, a sun gear shaft gear 6, an engine output shaft gear 7, Engine output shaft pinion 8, engine 9, connecting shaft gear 10, coupling sleeve pinion gear 11, coupling sleeve 12, coupling sleeve bull gear 13, coupling shaft 14, disc brake 15, band brake 16.

[0023] Single-row planetary gear transmission, disc brake, band brake, sun gear shaft gear, connecting shaft, connecting shaft gear, coupling sleeve, coupling sleeve pinion gear and coupling sleeve large gear form a two-stage forward and reverse transmission device. The two-stage forward and reverse transmission device is located between the starter generator and the engine, and can transmit pow...

Abstract

The invention discloses a starting power generation system with a two-stage forward and reverse speed changing device, belonging to the technical field of automobile electrical appliances, comprisinga starting generator, a single-row star gear transmission, a disc brake, a belt brake, a sun axle gear, a connecting shaft, a connecting shaft gear, a coupling sleeve, a coupling sleeve pinion and a coupling sleeve bull gear, etc. In the vehicle starting stage, the engine starting speed is low, and the two-stage transmission device can make the starting generator start the engine smoothly and efficiently. In the power generation stage, the engine ring gear speed is high, and there is an increasing transmission ratio between the ring gear and the output shaft, which will make the output shaft speed abnormally high. The two-stage speed changing device can make the starting generator work normally even when the engine ring gear speed is high.

Description

technical field [0001] The invention relates to an automobile starter generator, in particular to a starter generator system with a two-stage forward and reverse transmission device, which belongs to the technical field of automobile electric appliances. Background technique [0002] In the past, a starter and a generator were installed on a car, and the two work independently of each other. After the starting process is completed, the starter is idle. This will inevitably cause the starter to not work most of the time but occupy the limited space of the car, increasing The weight of the car is reduced, so the starter-generator integration technology is needed to overcome this shortcoming. [0003] In the vehicle starting stage, the engine starting speed is low, but a large starting torque is required; in the vehicle running stage, the engine ring gear rotates at a high speed, and the output shaft connected to the ring gear rotates at a higher speed. If the output shaft of ...
