Problems solved by technology

[0002]At present, the brake box on the rear axle of the electric tricycle and the rear axle tube are generally connected by welding. Due to the large deformation of the brake box after welding, the inner wall of the brake box The gap between the shoe and the outer wall of the hub, between the shoe block and the inner wall of the hub is not uniform, the braking effect is poor when braking, and even interference will occur, and the motor will be damaged; in addition, because the rear axle of the tricycle The bearings at both ends are fixed between the driving axle shaft and the re

Example Embodiment

[0033] see figure 1 and other views, the electric tricycle rear axle assembly, which is composed of the drive half shaft 43, the rear axle tube assembly 48, the bearing 49, the brake box assembly 51, the shoe block group 53, the wheel hub 55 and the rim 56. A bearing 49 is sleeved on the bearing mating surface 2. The bearing 49 is installed in the flange bearing groove 14 of the rear axle tube assembly 48 and the brake box bearing groove 28 of the brake box assembly 51, and the half shaft keyway 5 of the drive half shaft 43 and the hub. In the hub keyway 38 of 55, the drive half-drive 43 and the hub 55 are connected into one through the flat key 44; the hub taper mating surface 4 of the drive axle 43 is matched with the drive axle taper mating surface 37 of the hub 55; in the rear axle tube The brake box assembly 51 is installed on the flange 12 of the rear axle tube assembly 48 through the connecting piece in the brake box fixing hole 13 on the flange 12 of the assembly 48...

Abstract

The invention relates to the field of assembly which is installed on an electric tricycle rear axle. A bearing (49) which is arranged on a shaft matching surface (2) of a driving half shaft (43) in a sleeved mode is installed in a flange bearing groove (14) of a rear axle tube assembly (48) and a switch box bearing groove (28) of a switch box assembly (51), the driving half shaft (43) is connected with a wheel hub (55) through a flat key (44), a wheel hub taper matching surface (4) of the driving half shaft (43) is matched with a driving half shaft taper matching surface (37) of the wheel hub (55), the flange (12) is connected with a switch box (17) through a connecting piece, a hoof block assembly (53) is arranged at the inner side of the wheel hub (55), and the wheel hub is connected with a rim (56). The electric tricycle rear axle assembly has the advantages of being capable of enabling a bearing to be sealed between the flange and the switch box and preventing water and dust from entering, long in service life and easy to replace.

Description

technical field [0001] The electric tricycle rear axle assembly relates to the rear axle assembly field for electric tricycles composed of a driving half shaft, a rear axle tube assembly, a bearing, a brake box assembly, a shoe block set, a wheel hub and a rim. Background technique [0002] At present, the brake box on the rear axle of the electric tricycle and the rear axle tube are generally connected by welding. Due to the large deformation of the brake box after welding, the inner ring wall of the brake box and the outer ring wall of the hub, the shoe block group and the inner ring of the hub The gap between the walls is uneven, the braking effect is poor when braking, and even the phenomenon of interference will occur, and the motor will be damaged; in addition, because the bearings at both ends of the rear axle of the tricycle are fixed on the driving half shaft and the rear axle with elastic rings Between the tubes, due to the gap between the inner ring wall of the br...
