Problems solved by technology

[0003] In view of this, the present invention provides a radio-driven active suspension device, which is used to reduce the volume of the existing electromagnetic suspension, improve the structural form and energy transmission form of the existing electromagnetic active suspension, and improve its life and reliability. At the same time, the wireless energy transmission technology can be used to reduce the volume of its own energy storage device and improve the problem that the actuator cannot meet the actual use requirements at the maximum stroke and maximum output power.

Embodiment 1

[0023] Embodiment 1. A radio-driven suspension device includes a housing, an energy supply module 9, a tubular coil 4 located inside the housing, a permanent magnet 5, a ferromagnetic cylinder 6, a wireless receiving module 8, a wireless transmitting module 10, and a Actuator push rod 12, electronic control module 14, drive module 15, limit block 16, rectifier 17, coil fixing bracket 21, and vehicle body attitude sensor 20 located outside the housing.

[0024] The energized coil 4 , the rectifier module 17 and the wireless receiving module 8 are connected in sequence through wires and fixed together on the coil fixing bracket 21 , and the coil fixing bracket 21 protrudes out of the casing by being fixedly connected with an actuator push rod 12 .

[0025] Inside the ferromagnetic cylinder 6 there is a space for accommodating the reciprocating movement of the coil fixing bracket 21, and the permanent magnet 5 and the wireless transmission module 10 are jointly fixed on the inner ...

Embodiment 2

[0033] Such as figure 1 As shown, the upper suspension ring 1 is hinged with the vehicle body part, and the lower suspension ring 13 is hinged with the wheel part after being hinged with the actuator push rod. The buffer blocks 3 and 16 are the upper and lower dead center buffer devices for avoiding the overstretching or compression of the suspension, respectively. A permanent magnet 5 and a wireless transmission device 10 are embedded inside to form an internal permanent magnetic field and perform wireless transmission of electric energy. The high power density battery of the electric energy supply unit 9 is installed inside the shock absorber lower shell 18 to realize an integrated design. The control and driving part mainly includes the electronic control unit 14 and the driving device 15. The electronic control unit 14 can communicate with the ECU of the whole vehicle through CAN communication, receive the vehicle body posture information obtained by the vehicle body postu...

Abstract

The invention discloses an active suspension device driven by wireless. According to the specific structure of the device, an energization coil, a rectification module and a wireless receiving moduleare connected through wires in sequence and fixed on a coil fixing support, and the coil fixing support is fixedly connected with an actuator push rod and extends out of a shell; a space which allowsthe coil fixing support to move back and forth is formed in the a ferromagnetic cylinder, and a permanent magnet and a wireless sending module are connected through a wire and fixed on the inner wallsof the space; the wireless sending module is connected with a driving module and an energy supplying module through a wire in sequence; an electronic control module is connected with the energy supplying module through a wire and controls the energy supplying module to give out given energy signals; the electronic control module conducts communication with the external portion through a CAN bus;the wireless receiving module and the wireless sending module conduct energy transmission in a wireless transmission mode. The active suspension device driven by wireless is used for reducing the sizeof an existing electromagnetic suspension rack and improving the structural mode and energy transmission mode of an existing electromagnetic active suspension rack.

Description

technical field [0001] The invention belongs to the field of vehicle chassis control and relates to a radio-driven active suspension device. Background technique [0002] With the development of vehicle electrification, electromagnetic active suspension has received extensive attention. At present, most electromagnetic suspensions use magnetorheological or electrorheological fluids to exhibit different characteristics in different strength electromagnetic fields to adjust damping or stiffness. Chinese patent CN 104309438 invented a multi-functional suspension based on magnetorheological fluids based on this principle Suspension of vehicles under working conditions; a few use energized coils to adjust the vehicle attitude and body height under different magnetic fields, but usually the coils are used as the mover part and the permanent magnet is used as the stator part. A coil-based active suspension electromagnetic actuator invented by Chinese patent CN 101863210 and a moto...
