Embodiment Construction

[0012] Such as figure 1 As shown, the driving axle for electric police cars, patrol cars and golf carts according to the present invention includes a speed reducer 7, a sleeve weldment 12 and a half shaft 16, and the speed reducer 7 is used for power conversion and passes through The bolt 8 is connected with the casing welding piece 12, and a washer 11 is provided between the reducer 7 and the casing welding piece 12 to adjust the gap between the two. The leaf spring seat 10 is used to bear the load of the whole vehicle and the leaf spring seat 10. There is a shock absorber bracket mounting hole on the upper punch to facilitate the installation of the whole vehicle. It has wider versatility through reasonable structural design. The other end of the drive axle is equipped with a half shaft 16 and a bearing 15 is installed on the outside to move the half shaft. The shaft 16 is supported on the sleeve weldment 12, the outer layer of the half shaft 16 is covered with a half shaft ...

Abstract

The invention discloses a drive axle for an electric police car, a patrol car and a golf cart. The drive axle comprises a decelerator, a sleeve seaming piece and a half axle; a half axle sleeve is sleeved on the outer layer of the half axle, the decelerator is connected with the sleeve seaming piece through a bolt, and a shaft I and a shaft II are arranged on two sides of the inner part of a decelerator box body of the decelerator in turn; the half axle sleeve is inserted into the decelerator box body; the outer side of the shaft I is connected with a shaft gear II and then connected with a flat key on the shaft II; and a plate spring seat is arranged on the outer side of the half axle sleeve and provided with a damper bracket mounting hole. The drive axle has the advantages that: the interior of the main decelerator is provided with a secondary expanded helical gear deceleration mechanism, and various speed ratios can be designed by adjusting the tooth number, modulus, helical angle and modification coefficient of a gear so as to meet the speed ratio requirements of various vehicle types; the drive axle furthest lowers the cost and reduces the resource waste at the same time of meeting different requirements; and the drive axle has the characteristics of no abnormal sound, low noise, compact appearance, strong generality and the like.

Description

technical field [0001] The invention relates to an electric vehicle drive axle mechanism, in particular to a drive axle used for electric police cars, patrol cars and golf carts. 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 object of the present invention is to provide a drive axle for electric police cars, patrol cars and golf carts with low noise, compact appearance, strong versatility, and can reduce waste of resources, so that the same box can be Assemble different gears and finally achieve the purpose of different speed ratios. [0004] To achieve the above object, the present invention is achieved throu...
