An all-round steering system for electric vehicles based on in-wheel motors

Abstract

The invention discloses a hub motor-based electric automobile omni-directional steering system. The system comprises a central control system, a frame, a steering wheel and left front, right front, left rear and right rear wheels of the frame, and is characterized in that the frame is connected with a hub motor through a suspension seat which is fixedly arranged on a hub motor stator, wherein a rotor of the hub motor is fixedly connected with hubs of the wheels and is provided with a brake pad with brake calipers; the wheels all cooperate to finish steering motion through an independent steering mechanism and a linkage steering mechanism connected with the suspension seat. The electric vehicle using the omni-directional steering system can realize zero radius steering and cross running, the steering flexibility of the vehicle is good, the operation such as parking is easier, and the energy and the urban parking space are saved.

Description

technical field [0001] The invention relates to an electric vehicle omnidirectional steering system based on a hub motor. Background technique [0002] As of the end of 2013, the number of automobiles in my country has exceeded 137 million. The demand for oil has increased significantly, and the dependence on foreign oil has gradually increased. The country is facing more and more severe challenges in energy security. The level is more than 10% lower, and the rapid industrialization has led to aggravated pollution. Many major large and medium-sized cities in the country have successively experienced smog weather, which has seriously affected the production and life of the people. In order to solve the energy and environmental problems we are facing, the country has established a medium and long-term development plan for the development of new energy vehicles. At the same time, the increase in car ownership has led to road congestion and tight parking spaces. However, due to ...

Problems solved by technology

At the same time, the increase in car ownership has led to road congestion and tight parking spaces. However, due to the existence of steering bars in traditional cars, the steering angle of the front wheels is limited between -35°-+35°, and the steering flexibility is relatively low. Poor, the shifting parking operation is more difficult, the space required to complete the parking is larger, and the time is longer, resulting in a certain waste of energy and waste of urban parking space
