Problems solved by technology

However, due to the large space occupied by the deceleration mechanism, it is not possible to use twin tires and wheels commonly used in commercial vehicles, and it is difficult to install on the non-independent suspension of traditional commercial vehicles. It may also need to use custom-made rims, and the cost is also high.

Abstract

The invention discloses an electric wheel assembly, axle and vehicle suitable for twin-tire parallel loading wheels. The electric wheel assembly comprises wheels and a support shaft assembly, an innerrotor hub motor, a planetary gear reducer and a braking system. A planet carrier is connected with a wheel hub, the wheel hub connects a spoke and a wheel rim, a wheel support shaft passes through arotor sleeve, and hub bearings are arranged on the wheel support shaft to support the wheel hub and the whole wheel. The sun gear at one end of the rotor sleeve of the inner rotor hub motor is the power input of the planetary gear reducer, and the planet carrier is the power output. The planetary gear of planetary gear reducer adopts tower gear to realize larger transmission ratio under smaller axial length. The brake system adopts drum brake, the brake drum is connected with the rotor sleeve, and the braking force is amplified through the planetary gear reducer, which can reduce the braking force required by the brake system, and the electric motor can provide the electric braking force when braking. The electric wheel assembly can be used for the non-independent suspension of the commercial vehicle, and the cooling lubrication mode of the integrated cooling lubrication can be adopted to improve the performance.

Description

technical field [0001] The invention belongs to the technical field of electric drive of new energy vehicles, and in particular relates to an electric wheel assembly, an axle and a vehicle suitable for twin-tyre parallel mounted wheels. Background technique [0002] Traditional commercial vehicles generally adopt a centralized drive method, and their performance improvement is often limited by many aspects, such as: the transmission chain is long, and components such as drive shafts, transfer cases, and differentials are required, which affects the overall layout and lightweight , the overall low efficiency of the transmission system limits the number of driving axles, thus limiting the development of vehicles in the direction of super long and heavy load; a single engine provides power, and the power transmission is in a series transmission mode, resulting in poor reliability and fault tolerance ; The specific power is low and the power is limited. Therefore, the developme...
