Embodiment Construction

[0012] Such as figure 1 As shown, the semi-floating drive axle for electric sightseeing cars and electric trucks according to the present invention includes a speed reducer 8, an axle housing 6 and a half shaft 7, and the speed reducer 8 is used for power conversion and is connected by bolts 9 is connected with the axle housing 6, and the leaf spring seat 10 is welded on both sides of the axle housing 6. The leaf spring seat 10 is used to bear the load of the whole vehicle and the shock absorber bracket mounting hole is punched on the leaf spring seat 10 to facilitate the installation of the whole vehicle. Installation, through reasonable structural design to make it more versatile, the bearing 13 installed on the outer end of the half shaft 7 can support the half shaft 7 on the axle housing 6; the outer retaining ring 11 is pressed on the bearing 13 , an oil seal 12 is provided on the outer side of the outer retaining ring 11 to seal the drive axle part, which can protect imp...

Abstract

The invention discloses a semi-floating drive axle for an electric sightseeing vehicle and an electric cargo truck, which comprises a reducer, an axle case and an axle shaft, wherein the reducer is connected with the axle case through a bolt; a shaft I and a shaft II are arranged on two sides in a reducer box of the reducer in turn; the outer end of the shaft II is meshed with a bull wheel and the bull wheel drives a differential shell on one side to rotate; the outer side of the shaft I is connected with a shaft gear II and then connected with a key on the shaft II; and plate spring bases are welded on two sides of the axle case and are provided with damper support mounting holes. The semi-floating drive axle has the advantages that: a two-stage helical gear reducing mechanism is arranged in a main reducer, and various speed ratios are designed by adjusting the tooth number, modulus, helical angles and modification coefficients of gears so as to meet the requirements on speed ratios of various vehicles; and under the condition of using the same reducer box, the various speed ratios can be realized by replacing gears, and under the condition of using the same axle case, the matching with various steel plate springs is realized by replacing the plate spring bases.

Description

technical field [0001] The invention relates to an electric vehicle drive axle mechanism, in particular to a semi-floating drive axle for electric sightseeing cars and electric trucks. Background technique [0002] At present, the types of new energy vehicles produced and sold on the market are complex and have a wide range of uses, so the requirements for drive axles are also ever-changing, and most drive axles have a single speed ratio and a fixed structure, and one axle can only adapt to one or two models. A great waste. Contents of the invention [0003] In view of the above defects, the purpose of the present invention is to provide a semi-floating drive axle for electric sightseeing cars and electric trucks with low noise, compact appearance, strong versatility, and capable of reducing waste of resources, so that the same type of tank can The body can be assembled with different gears and finally achieve the purpose of different speed ratios. [0004] To achieve th...
