Problems solved by technology

[0003] The structure of a three-wheeled motorcycle is very different from that of a low-speed car. A low-speed car requires a large load, and it has enough space for its transmission system. The advantage of a three-wheeled motorcycle is its compact structure, so its transmission system layout is very limited
But these two kinds of three-wheeled motorcycles have small speed range, low transmission efficiency, poor climbing ability, and cannot adjust the speed and torque properly according to road conditions and load conditions, thereby reducing the fuel economy and vehicle performance of the three-wheeled motorcycles. Carrying capacity

Embodiment Construction

[0017] A transmission device for a three-wheeled motorcycle with a reverse gear function, which includes a main transmission unit and an auxiliary transmission unit, and a universal coupling is arranged between the auxiliary transmission unit and the main transmission unit. The main transmission unit is a conventional transmission, usually with 4 or 5 forward gears.

[0018] figure 1 The detailed structure of the auxiliary transmission unit is shown. Such as figure 1 As shown, after the upper box body 1 and the lower box body 3 are combined, an auxiliary gearbox body is formed and two bearing installation holes are formed on the box body walls on the left and right sides, and the second bearing 13 is housed in the bearing installation holes.

[0019] The input shaft 2 is a gear shaft, and the gear on the input shaft 2 is a primary driving gear 29. The input shaft 2 is supported on the second bearing 13 on one side of the auxiliary transmission case, and the end of the input ...

Abstract

The invention discloses a speed changing device of a motor tricycle with gear reversing function, which comprises a main speed changing unit, an auxiliary speed changing unit and a driving device, wherein the auxiliary speed changing unit enables a gear reversing mechanism which realizes the gear reversing function to be arranged in the auxiliary speed changing unit, and the driving device is connected between the auxiliary speed changing unit and the main speed changing unit. Because the auxiliary speed changing unit is arranged, on the basis that original integral space is reasonably used, the speed range of the motor tricycle is greatly enhanced, thereby the economical efficiency of fuel and the whole carrying capacity of the motor tricycle are increased. Meanwhile, because the gear reversing mechanism and a mutual interlocking gear are arranged in the auxiliary speed changing unit, the space of an auxiliary gear box casing is fully used, the manufacturing cost is greatly decreased, the gear reversing demand is satisfied, and the stage changeover reliability is enhanced.

Description

technical field [0001] The invention relates to the technical field of three-wheeled motorcycles, in particular to a transmission device for three-wheeled motorcycles. Background technique [0002] Known three-wheel motorcycle, its total mass is generally below 750 kilograms, because its compact structure, turning radius are little, when using in narrow roadway, still have irreplaceable advantage. [0003] The structure of a three-wheeled motorcycle is very different from that of a low-speed car. A low-speed car requires a large load, and it has enough space for its transmission system. The advantage of a three-wheeled motorcycle is its compact structure, so its transmission system The layout is very limited. The power unit of the three-wheeled motorcycle usually adopts a single-cylinder gasoline engine or a multi-cylinder gasoline engine. The single-cylinder gasoline engine is integrated with the main gearbox. The two are collectively called the "engine". The power output...
