Embodiment 1

[0042] Please refer to figure 1 , figure 1 The specific structure of the reverse gear 10 provided in Embodiment 1 is shown.

[0043] Please refer to figure 1 The reverse gear 10 includes a casing 100, a rear end cover 101, a spline shaft 110, a reverse bevel gear 120, a forward bevel gear 130, a clutch 140, a shift fork 150, an axial limiter 160, a second A bearing 170 , a second bearing 180 , a third bearing 190 and a shift positioning part 200 .

[0044]Among them, the reverse bevel gear 120, the forward bevel gear 130, the clutch 140, the shift fork part 150, the axial limit part 160, the first bearing 170, the second bearing 180, the third bearing 190 and the shift positioning part 200 It is arranged in the case 100. One end of the spline shaft 110 is located inside the housing 100 , and the other end is located outside the housing 100 . The casing 100 is closed by a rear end cover 101 . The axial limiting portion 160 is used to limit the relative position of the spl...

Embodiment 2

[0068] Please refer to Figure 5 , Figure 5 The specific structure of the three-wheeled motorcycle 20 provided by this embodiment is shown.

[0069] The three-wheeled motorcycle 20 has the reverse gear 10 provided in the above-mentioned embodiment 1. The three-wheeled motorcycle 20 is provided with the reverse gear 10 to realize the backward or forward movement of the locomotive, which can solve the damage to the reverse gear 10 casing and the early wear and tear of the gears. The problem of solving the problem increases the service life of the reverse gear 10, and avoids the danger brought to the three-wheeled motorcycle 20 and the user due to the failure of the reverse gear 10.

Abstract

The invention discloses a reverse gear device and a motor tricycle and relates to the field of reverse gear devices. The reverse gear device comprises a shell, a spline shaft, a reverse gear bevel gear, a forward gear bevel gear, a clutch, a gear shifting fork part and an axial limiting part. The clutch is matched with a spline of the spline shaft and is located between the reverse gear bevel gear and the forward gear bevel gear. The gear shifting fork part is rotationally arranged in the shell so as to drive the clutch to be selectively matched with the reverse gear bevel gear or the forward gear bevel gear. The axial limiting part is arranged between the spline shaft and the shell and is used for limiting the axial movement of the spline shaft. The reverse gear device can solve the problem that the reverse gear device axially moves in the shell due to axial force of the spline shaft, and consequently the shell is punctured and is damaged, the installation precision and the transmission rigidity of the gears in the reverse gear device are improved, the problem that the gears of the reverse gear device are abraded in the early stage is solved, the service life of the reverse gear device is prolonged, and the risk brought to locomotives and users due to failure of the reverse gear device is avoided.

Description

technical field [0001] The invention relates to the field of reverse gears, in particular to a reverse gear and a three-wheeled motorcycle. Background technique [0002] The three-wheel motorcycle not only needs to move forward, but also may need to move backward, so that the three-wheel motorcycle can flexibly adjust the position of the body, so the three-wheel motorcycle is provided with a reverse gear, through The reverse gear is used to realize the forward and backward switching of the three-wheeled motorcycle. The housing of the reverse gear is often damaged by the spline shaft, and the early wear and tear of the gears in the reverse gear causes the reverse gear to fail, which brings danger to the three-wheeled motorcycle and the user. Contents of the invention [0003] The first object of the present invention is to provide a reverse gear, which can prevent the spline shaft from moving axially in the casing due to the axial force, thereby puncturing the casing and c...
