Problems solved by technology

[0003] At present, the most commonly used scheme of the wheel-side reduction device is a standard one-stage planetary gear reduction device or a two-stage planetary gear reduction device, which adopts a one-stage deceleration form or a two-stage deceleration form, but it has the following problems: The radial space of the one-stage planetary gear reducer is too large, and the two-stage planetary gear reducer has low efficiency, heavy weight, and high cost, making it difficult to meet the requirements of the wheel-side planetary gear reducer for Formula E racing cars.

Abstract

The invention relates to a wheel edge planetary gear speed reducer for an electric formula racing car. The wheel edge planetary gear speed reducer for the electric formula racing car comprises a planetary gear mechanism, a double-web planet carrier mechanism and a gear box mechanism. According to the wheel edge planetary gear speed reducer for the electric formula racing car, the form of planetarygear sets arranged in series is used to replace the form of a single planetary row or a plurality of planetary rows in the prior art, so that the structure of the speed reducer is simplified, and therequirement on a large speed ratio of the speed reducer in a limited wheel edge installation space of the electric formula racing car is realized.

Description

technical field [0001] The invention relates to a wheel-side planetary gear reduction device for an electric formula racing car, which includes a planetary gear mechanism, a double-web planetary frame mechanism and a gear box mechanism, and replaces the previous single planetary row or multi-planetary row with the form of a row planetary gear set The form simplifies the structure of the deceleration device, and realizes the demand for a large speed ratio of the deceleration device in the limited wheel-side installation space of the electric formula car. Background technique [0002] According to the system structure, the electric formula car can be mainly divided into: centralized drive and distributed drive. For the centralized drive form, there are defects such as excessive motor backup power, low efficiency, and heavy weight. For the distributed drive form of the four-wheel side motor, it has high efficiency, light weight, can independently distribute the four-wheel torq...
