Abstract

The invention relates to a driven wheel mechanism and a vehicle. The driven wheel mechanism comprises a wheel carrier, a hub, an electromagnetic brake, a wire harness rotator, a steering motor and a main control processor, the rotation angle of the hub is fed back to the main control processor through an encoder arranged on the steering motor to calculate the steering angle and position of the hub. The electromagnetic brake and the wire harness rotator are both arranged in the wheel carrier; the electromagnetic brake comprises a base, a wire harness and a brake pad, a first gap is formed between the base and the brake pad, the first gap is a set value, the brake pad is installed on the hub, when the electromagnetic brake conducts braking, the friction plate in the base pops up and is tightly attached to the brake pad for mutual friction, and at the moment, the first gap is zero. When the electromagnetic brake stops braking, the first gap is recovered to the set value. The brake experience is good, and the safety can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of logistics handling, in particular to a driven wheel mechanism and a vehicle. Background technique [0002] Nowadays, in the field of industrial vehicles, new products are constantly being launched, and the driven wheel mechanisms used in vehicles with large tonnage, heavy loads, all-wheel braking, and multi-directional driving need to implement more and more functions, which are becoming more and more refined and Multi-purpose, such as additional braking function (industrial vehicles have a large tonnage, and under special application conditions, each wheel is required to have a braking function to meet the braking standards required by the national standard), front and rear left and right steering functions, and even It is the steering function of any angle and direction within 360°. In special cases, it may also require the steering function of unlimited rotation and unlimited number of turns; when the ...
