Double-trailing arm type steering independent suspension for electric bus driven by wheel-side motors

Abstract

The invention relates to a double-trailing arm type steering independent suspension for an electric bus driven by wheel-side motors. The double-trailing arm type steering independent suspension comprises a left suspension, a right suspension, steering linkages, a steering rocker arm, an angle sensor and a steering actuating cylinder. According to the double-trailing arm type steering independent suspension disclosed by the invention, drive motors are arranged at wheel positions of the bus; each drive motor is located on the side of an output shaft of each of speed reducers; each speed reducer is fixed to each of supporting arms; the output shaft of each speed reducer penetrates through a center hole of each supporting arm and is connected with each of wheel-side structures of the bus, and a wheel of each wheel-side structure is driven to rotate, so that the driving to the bus is realized; the supporting arms are designed with high load-bearing performance to replace a conventional supporting arm structure, so that a shock absorber and a steering mechanism can be directly connected with the supporting arms, the steering and the locking of the bus are facilitated, and beside, the purposes of increasing the interior space of the bus and reducing the height of a bus floor can be realized.

Description

[0001] Technical field: [0002] The invention relates to the technical field of suspensions for new energy passenger cars, in particular to a double trailing arm steering independent suspension for electric passenger cars driven by wheel side motors. [0003] Background technique: [0004] With the world's energy crisis and air pollution becoming more and more serious, people are paying more and more attention to the development of new energy vehicles. In my country, in order to promote the development of energy vehicles, the country has issued a series of policies and regulations. The development of new energy vehicles is unstoppable . [0005] In the field of passenger cars, electric passenger cars have also been developed accordingly. However, the existing electric passenger cars only change the traditional fuel-powered form into an electric form, and the overall structure of the passenger car has not been correspondingly developed. With the development of passenger car tech...

Problems solved by technology

However, the existing support arms for supporting the reducer and the drive motor have poor load-bearing and supporting capacity, and most of them can only support the drive motor, the reducer and the wheel structure connected with the reducer, and at most support the airbag assembly. The steering system can only be connected to the steering mechanism through additional parts. The steering force of the steering mechanism needs to be transmitted to the support arm through additional parts. The steering requires a large force and is inconvenient to operate.
