Problems solved by technology

[0011] The disadvantage of this type of transmission is that the engine, gearbox and pedal crankshaft are installed in the gearbox at the same time
This complicates both the design and modernization of the transition from conventional bicycles to e-bikes

Embodiment 1

[0066] A better implementation of the electric bicycle transmission is as follows:

[0067] Inside the gearbox (1), the input shaft (2) is geared to the intermediate shaft (9).

[0068] The first and second parts of the mechanical transmission are located between the intermediate shaft (9) and the output shaft (5).

[0069] The second disc-shaped member (7) and the third disc-shaped member (8) of the first part of the mechanical transmission are compressed and mounted on the intermediate shaft (9) and the output shaft (5) respectively. The shaft-mounted element of the second disc member (7) or third disc member (8) is the first overrunning clutch (11), which only transmits the direction of rotation from the intermediate shaft (9) to the output shaft (5). to achieve figure 1 , the third disc member (8) is installed on the first overrunning clutch (11), and the second disc member (7) is fixed on the intermediate shaft (9).

[0070] The fourth disc-shaped member (12) and the f...

Embodiment 2

[0094] Example 2 is similar to Example 1. But it is different from Embodiment 1 in that the second overrunning clutch (14) and the sixth disc member (25) are connected with the output shaft (5).

[0095] The second overrunning clutch (14) is uncontrollable. On the contrary, for more comfortable use of the bicycle when the engine is idling, a sixth disc member (25) is mounted on the output shaft (5) of a lockable overrunning clutch. In the locked state, the overrunning clutch acts as a positive connection, and in the unlocked state, the overrunning clutch only transfers the direction of rotation from the output shaft (5) to the sixth disc member (25). At the same time, the corresponding control element of the lockable overrunning clutch is mounted on the bicycle handlebar as a reset lever. When the reset lever is pressed, the overrunning clutch is locked and the engine can be started by depressing the pedal. When the reset lever is released, the overrunning clutch is unlocke...

Embodiment 3

[0098] Example 3 is similar to Example 1. The difference is that the second overrunning clutch (14) and the first disc member (6) are connected with the pedal disc member (15).

[0099] The second overrunning clutch (14) is uncontrollable. On the contrary, in order to use the bicycle comfortably when the engine is idling, the first disc member (6) is fixed on the pedal disc member (15) by a lockable clutch (20) ( figure 2 ). In the locked state, the clutch (20) acts as a solid connection, and in the unlocked state acts as a one-way clutch, transmitting only the direction of rotation from the first disc member (6) to the pedal disc member (15). In this case, the corresponding control element of the clutch (20), located on the handlebar of the bicycle, is a reset lever. When the lever is pressed and held, the clutch (20) is locked and the engine can be started by pedaling. When the lever is released, the clutch (20) is unlocked.

[0100] In special cases, a clutch (20) can...

Abstract

The invention relates to the field of wheeled vehicles which are human-powered and are additionally equipped with an internal combustion engine. A transmission has two purposes. The first is to transmit power from the engine to a pedal disc element, from which power is transmitted to a wheel. The second is to transmit power in a reverse direction to the engine for starting same. A motorized bicycle transmission comprises a mechanical transmission including a reduction gear and a first disc element on a crankshaft axis of the pedals. The mechanical transmission comprises two parallel sections.The first section transmits power with a first transmission ratio only in a direction from the input shaft of the reduction gear to the first disc element. The second section transmits power with another transmission ratio only in a direction from the first disc element to the input shaft of the reduction gear. Simplification of the installation of a transmission when motorizing a bicycle is achieved by the invention. The description of the invention comprises a plurality of embodiment examples.

Description

technical field [0001] The technical solution claimed in the present invention relates to the field of wheeled vehicles, which are driven by human power and an internal combustion engine. Speed ​​changer of the present invention has two big effects: [0002] —Pedal disc member that transmits the rotational motion of the engine to the pedal drive, and transmits the power to the wheels. [0003] - Reverse transmission of the rotational movement (from the pedal disc member or pedal crankshaft to the engine), starting the engine. Background technique [0004] For example, the known electric bicycle transmission (European Patent Publication No. ЕР0378397В1 IPC В62М23 / 02, В62М 7 / 02, 1995) is a belt drive that transmits power from an internal combustion engine to a gearbox. The constant transmission ratio of the gearbox is in the range of 3:143:1 (15:1 is the best), compresses 4 shafts, and fixes them with gears and sprockets. The centrifugal clutch is mounted on the input shaft...
