Abstract

The invention provides a double wishbone independent suspension used for a wheel hub motor, and relates to the technical field of automobile parts. The double wishbone independent suspension comprisesan upper wishbone and a lower wishbone which are arranged in parallel at an interval, wherein one end of the upper wishbone and one end of the lower wishbone are connected to the upper and lower endsof a steering knuckle through a T-shaped pivot mechanism respectively; the other ends of the upper wishbone and the lower wishbone are connected onto a rigid arm through pivots respectively; the rigid arm is fixedly connected onto a car body; and the steering knuckle is connected with a wheel hub connecting shaft and a steering transmission mechanism. The T-shaped pivot mechanism comprises a transverse shaft and a vertical shaft connected to the middle part of the transverse shaft in an included angle of 80 to 90 degrees with the transverse shaft, the upper wishbone is rotatably connected onto the transverse shaft in a sleeving mode, and the steering knuckle is rotatably connected onto the vertical shaft in the sleeving mode. The double wishbone independent suspension solves the problem that a double wishbone independent suspension in the prior art cannot serve as a drive axle of the wheel hub motor.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a double-wishbone independent suspension for hub motors. Background technique [0002] In-wheel motor technology is also called in-wheel motor technology. Its biggest feature is the integration of power, transmission and braking devices into the wheel hub, which can greatly simplify the mechanical parts of the car. For traditional vehicles, clutches, transmissions, drive shafts, The differential and even the transfer case are essential, and these components are not only heavy, making the structure of the vehicle more complicated, but also have the problems of regular maintenance and failure rate, but the in-wheel motor is a good solution To solve this problem, in addition to a simpler structure, vehicles driven by in-wheel motors can achieve better space utilization, and the transmission efficiency is also much higher. [0003] The existing double-wishbone independent suspens...
