Support disconnected type fixed guide pin split brake for hub motor

Abstract

The invention discloses a support disconnected type fixed guide pin split brake for a hub motor. A brake disc, an upper pincer body and a lower pincer body are included, the opposite inner side facesof the upper pincer body and the lower pincer body are provided with friction plates, the two sides of the upper pincer body are provided guide pins vertical to a plane where the brake disc is located, a support separated from the brake disc is arranged outside the lower pincer body, the projection of the support in the axial direction of the brake disc is in a C shape, the direction of an openingclamped between the upper pincer body and the lower pincer body is opposite to the direction of an opening of the C-shaped support, and the guide pins are fixed to the support. The support disconnected type fixed guide pin split brake has the beneficial effects that the upper pincer body and the lower pincer body can be moved out in the radial direction of the brake disc on the premise that the support is not dismounted, the friction plates are conveniently replaced, and the assembling and maintaining efficiency of the hub motor brake is improved; and the split pincer bodies are adopted, theupper pincer body and the lower pincer body are connected through a connecting bolt, dismounting of the brake is facilitated, the size of a clamp can be better adjusted according to the change of thethickness of the brake disc.

Description

technical field [0001] The invention relates to the technical field of hub motors, in particular to a bracket disconnected fixed guide pin split brake for hub motors. Background technique [0002] The in-wheel motor technology is also known as the in-wheel motor technology. The in-wheel motor is one of the important directions for the development of new energy vehicles. It can integrate the power, transmission and braking systems into the wheel hub to simplify the structure of the vehicle. [0003] The braking structure in the hub motor is arranged inside the hub motor. For example, in the Chinese patent literature, the application number is CN2017108025710, and the publication date is an invention patent named "a motor brake structure" published on January 12, 2018. The application discloses a compact structure, good heat dissipation, Stable motor brake structure. It includes a motor, a brake ring and a caliper assembly. The motor includes a rotor part, a transmission sha...
