Abstract

The invention discloses a drive-by-wire four-wheeled steering and driving integrated suspension system which comprises a servo motor, a support, a worm and gear speed reducer, a damping spring, a damper, a damper supporting rod, a main pin (including an upper portion and a lower portion), a braking disc, a brake caliper, an upper foldable arm, a lower foldable arm, a supporting fork frame, a copper gasket, a rubber limiting block, a wheel turning angle sensor, a single chip microcomputer and a CAN bus system. The brake caliper is fixedly connected to the supporting fork frame, and the brakingdisc is fixedly connected to a hub and rotates together with wheels. The servo motor fixed to the support is connected with a worm, and the worm is meshed with a worm wheel. The damping spring is located between the upper portion and the lower portion of the main pin, and the upper portion and the lower portion of the main pin are connected through an upper supporting rod, the upper foldable arm,the lower foldable arm and a lower supporting rod of the bypass damper and the supporting fork frame. The damper is connected with an upper supporting rod and the lower supporting rod of the damper through a rotary pair. The drive-by-wire four-wheeled steering and driving integrated suspension system has the advantages that a steering mechanism does not occupy additional space while drive-by-wirefour-wheeled independent steering is achieved, and meanwhile steering errors are decreased to the most degree.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a suspension system integrated with wire-controlled four-wheel steering and drive. Background technique [0002] The rise of new energy vehicles, mainly electric vehicles, provides new ideas for solving the oil crisis and environmental pollution problems. In recent years, the development of in-wheel motors and steering-by-wire technology has attracted great attention. Compared with the previous generation of electric power steering system, the steering-by-wire system has better operational stability. Since the steering wheel and the steering wheel do not need to be connected by a mechanical mechanism, on the one hand, it gets rid of some installation and positioning restrictions of the steering system itself, and on the other hand, it also gets rid of the motion interference between the steering system and other systems, and also reduces The quality of the ...
