Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0043] The chassis provided by the embodiments of the present application can be applied to vehicles with low speed and light weight. For example, it can be applied to some low-speed logistics vehicles, which can be manned logistics vehicles or unmanned logistics vehicles. It can also be applied to some toy cars, which include remote control cars that can be held in hand, and toy cars that can be driven by people (for example, small motorcycles and toy cars driven by children, toy trains driven by staff, etc.). It can also be applied to some small tricycles and small mopeds.

[0044] The embodiment of the present application provides a chassis, which includes a travel assembly with a braking function, and the travel assembly inc...

Abstract

The invention relates to a chassis and a vehicle, and belongs to the technical field of vehicles. The chassis comprises an advancing assembly with a braking function, and the advancing assembly comprises a hub motor, a steering knuckle, a braking worm gear, a braking worm and a braking motor, wherein the hub motor comprises a rotor and a stator, the braking worm gear is fixed on the rotor, and thestator is fixed on the steering knuckle; the brake worm is rotatably connected with the steering knuckle, the brake worm wheel is meshed with the brake worm, the brake worm wheel and the brake worm meet a self-locking condition, and the brake motor is used for controlling the rotation of the brake worm. By the application, the technical problem that the brake device is more complex in structure,so that the manufacturing cost of the brake device is higher, can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a chassis and a vehicle. Background technique [0002] Vehicle braking is divided into two types: driving brake and parking brake. Among them, driving brake refers to controlling the vehicle to gradually decelerate while the vehicle is running, and parking brake refers to preventing the vehicle from slipping when the vehicle is parked. car. For some large vehicles, such as cars and trucks, due to their large mass and speed, their braking is more difficult. Generally, special service braking devices are used to achieve service braking, and special parking brakes are used. The two sets of service brake devices and the parking brake device are separated from each other, and the structure is relatively complicated. [0003] With the development of the logistics industry, more and more logistics vehicles have appeared, and these logistics vehicles often have lower speed a...
