Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0014] a kind of like figure 1 The shown electric vehicle high and low shift reducer includes an input shaft 1, an output shaft 2, and an intermediate shaft 3, and a first input gear 4 and a second input gear 5 are arranged empty on the input shaft 1. A third intermediate gear 6 and a fourth intermediate gear 7 are fixedly sleeved on the intermediate shaft 3, and a fifth output gear 8 meshing with the fourth intermediate gear 7 is fixedly sleeved on the output shaft 2. The input shaft 1 is provided with a shift fork mechanism 9 for making the first input gear 4 and the second input gear 5 respectively mesh with the third intermediate gear 6 and the fourth intermediate gear 7 to generate power transmission.

[0015] In the present invention, different combined power transmissions between the first input gear 4 and the second input gear 5 ...

Abstract

The invention discloses a high-low gear conversion decelerator for an electric vehicle, comprising an input shaft, an output shaft and an intermediate shaft, wherein a first input gear and a second input gear hollowly sleeve the input shaft; a third intermediate gear and a fourth intermediate gear fixedly sleeve the intermediate shaft; a fifth output gear, which is meshed with the fourth intermediate gear, fixedly sleeves the output shaft; a forking mechanism, which is used for enabling the first input gear and the second input gear to be independently correspondingly meshed with the third intermediate gear and the fourth intermediate gear so as to generate power transmission, is arranged on the input shaft. The high-low gear conversion decelerator realizes the high-low gear power conversion through different power transmission ratios of the input gears and the intermediate gears, thereby meeting the condition that the electric vehicle to normally travel under identical battery performance and different working conditions, and improving the driving ability of the electric vehicle.

Description

technical field [0001] The present invention relates to a speed reducer, in particular to a speed reducer that can be used in electric vehicles to switch between high and low speed units, and can be applied to direct motor-type electric car drive axles for cargo, electric police booth car drive axles, electric Visit the sightseeing driving bridge and so on. Background technique [0002] Due to its advantages of environmental protection, energy saving and cleanliness, electric vehicles have developed rapidly in recent years. [0003] The current fixed speed ratio of the electric vehicle reducer cannot meet the normal driving of the electric vehicle under different working conditions. Therefore, it is necessary to design a new high-low gear conversion reducer for the electric vehicle to improve the existing situation. Contents of the invention [0004] In view of the deficiencies in the above-mentioned prior art, the present invention aims to provide a high-low gear convers...
