Problems solved by technology

[0002] Most of the existing electric buses are refitted. Since the power supply assembly is installed between the front axle and the rear axle and under the floor, the position of the rear suspension device must be raised. Due to the limitation of the floor height, the passenger door is generally Three-step steps increase the time required for passengers to get on and off the bus and reduce transportation efficiency

Abstract

The present invention relates to a trolley wireless electric bus back-suspension device, belonging to the field of vehicle front-suspension device structure technology. It is characterized by that its rear spring assembly is fixed on the spring bracket, its rear shock absorber assembly is placed between frame assembly and rear spring assembly, so that the mounting height of back-suspension device can be lowered.

Description

1. Technical field: [0001] The invention relates to a rear suspension device of a trackless wireless electric bus, and belongs to the technical field of vehicle front suspension device structures. 2. Background technology: [0002] Most of the existing electric buses are refitted. Since the power supply assembly is arranged between the front axle and the rear axle and under the floor, the position of the rear suspension device must be raised. Due to the limitation of the floor height, the passenger door is generally The three-step step increases the time it takes for passengers to get on and off the bus and reduces transportation efficiency. 3. Content of the Invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and to provide a rear suspension of a trackless wireless electric bus that can move the power supply assembly backwards, reduce the floor height of the passenger area, and realize the second-leve...
