Low-floor chassis platform integrating hub motor

Abstract

The invention discloses a low-floor chassis platform integrating a hub motor. The low-floor chassis platform comprises a lower vehicle body, a low-voltage control element, a wheel assembly, Macphersonsuspensions, a multi-connecting rod and a transverse leaf spring independent suspension, wherein a front suspension and a rear suspension of the lower vehicle body are independently controlled, and atransmission shaft and a differential mechanism are not arranged between the front suspension and the rear suspension; the Macpherson suspensions are arranged on the front suspension of the lower vehicle body, and a transverse stabilizer rod is installed to be matched with the Macpherson suspensions; the transverse stabilizer rod spans between the Macpherson suspensions on wheels on the two sidesof the front suspension; the wheel edges of the front suspension integrate a traditional caliper and a disc brake; the front part of the lower vehicle body is a chassis platform front cabin space forintegrating and installing the low-voltage control element; and the middle rear part comprises a high-voltage control element. According to the low-floor chassis platform, the weight of the whole platform is effectively reduced, the height of a chassis is reduced, the weight of a whole vehicle is effectively reduced, the system efficiency is improved, the loading volume is increased, the loadingratio of the whole vehicle is improved, meanwhile, better bearing capacity can be obtained, and the expansion performance is high.

Description

technical field [0001] The invention relates to a chassis structure in the field of new energy vehicles, in particular to a low-floor chassis platform integrated with hub motors for new energy commercial vehicles. Background technique [0002] With the rapid development of the domestic new energy vehicle industry, electric commercial vehicles for urban distribution have received widespread attention. However, most of the electric commercial vehicles currently on the market are modified on the basis of traditional gasoline vehicles or diesel vehicles. The central motor is used to replace the engine. The weight of the vehicle is heavy, the ground clearance of the chassis is high, and the load capacity and loading space are limited. High energy consumption cannot meet the needs of the logistics industry for large loading space, high load-to-weight ratio and long battery life of vehicles. [0003] With the development of direct drive technology for distributed drive hub motors,...
