Problems solved by technology

[0002] Automobile electrification has been widely used in passenger cars (cars), especially in urban buses. Currently, the methods used are generally centralized drive, decentralized drive, and multi-wheel single-tire direct drive. , centralized drive is simply to replace the transmission engine with a motor, this method has a large power loss and short battery life; while the decentralized drive, multi-wheel single-tire drive mode, is to use the wheel side drive to integrate the motor reducer bracket Direct drive, and this method is only suitable for large buses over 10 meters. If small and medium-sized vehicles use multi-wheel drive, it will affect the design layout of the vehicle

Abstract

The invention discloses a hub speed reducer which comprises a hub (1). A fixing support (2) is fixedly arranged on one side of the hub (1), and a double-tyre steel rim (6) is fixedly arranged on the other side of the outer edge of the hub (1). A first reduction gear is fixedly arranged in the fixing support (2) and connected with a connecting shaft (4), a second reduction gear is arranged at the extending end of the connecting shaft (4), and an oil mist separator (7) is fixedly arranged at the upper end of the first reduction gear. The two reduction gears are arranged on the hub and the fixing support, and the double-tyre steel rim is fixedly arranged on the hub, so that the transverse space is saved; the oil mist separator and a water circulating structure are adopted, so that the lubricating effect and the cooling effect are improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of manufacturing high-speed gear transmission reducers, in particular to a hub reducer. Background technique [0002] Automobile electrification has been widely used in passenger cars (cars), especially in urban buses. Currently, the methods used are generally centralized drive, decentralized drive, and multi-wheel single-tire direct drive. , centralized drive is simply to replace the transmission engine with a motor, this method has a large power loss and short battery life; while the decentralized drive, multi-wheel single-tire drive mode, is to use the wheel side drive to integrate the motor reducer bracket Direct drive, and this method is only suitable for large buses over 10 meters, if the small and medium-sized vehicles use multi-wheel drive, it will affect the design layout of the vehicle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wheel hub...
