Embodiment 2

[0043] This embodiment discloses an electric wheel, which is equipped with the multifunctional parking brake described in Embodiment 1, the multifunctional parking brake is installed between the steering knuckle 29 and the steering knuckle support mechanism 30, and the outer shell of the parking device and the The steering knuckle is fixedly connected, so that the entire multi-functional parking brake occupies the inner space of the wheel suspension, and integrates ABS and central inflation and deflation functions, which will not increase the width of the wheel and the vehicle. It is compact in structure and easy to maintain. It is suitable for use Use in heavy vehicles driven by electric wheels.

[0044] Such as Figure 3-Figure 5 As shown, one end of the air pipe communicates with the first air chamber, and the other end passes through the motor shaft 23 and communicates with the second air chamber 26 of the rim end cap 25 arranged on the electric wheel rim 24, and the end o...

Abstract

The invention relates to a multifunctional parking brake and an electric wheel. The multifunctional parking brake comprises a shell, wherein a first end tooth disc and a second end tooth disc are arranged in the shell, an ABS gear ring is fixed to the first end tooth disc, an ABS sensor is arranged on the shell, the ABS gear ring can be connected with a motor shaft, and the second end tooth disc is connected with a driving assembly, and can make contact with or be separated from the first end tooth disc under the action of the driving assembly; one end of the shell is provided with a first airchamber, the first air chamber is communicated with one end of an air pipe, the air pipe is detachably fixed to the shell in a sealed mode, and the other end of the air pipe penetrates through the shell and is used for being connected with an inflating valve. According to the parking brake, the ABS and the central inflating and deflating functions are integrated, so compact structure arrangementof the electric wheel is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric wheels, in particular to a multifunctional parking brake and electric wheels. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The electric wheel technology is also called the built-in motor technology in the wheel. The motor is also called the hub motor. The biggest feature is that the power device, the transmission device and the braking device are all integrated into the wheel hub, which greatly simplifies the mechanical part of the electric vehicle. Compared with other driving forms, it has many advantages such as short transmission chain, high transmission efficiency and flexible layout. The obvious advantages of electric vehicles using electric wheel technology in terms of overall vehicle layout, dynamic performance and control have attracted widespread attention ...
