Variable resistance manual brake control device

Abstract

The invention discloses a variable resistance hand control brake maneuvering device which comprises a base, an upper end cover and a sliding resistor. One end of the upper end cover is hinged to the base. The sliding resistor comprises a sliding resistor disc, a sliding resistor block and a rotating pointer. The sliding resistor disc is fixedly mounted on the base, one end of the rotating pointer is fixedly connected to the upper end cover, and the sliding resistor block is fixedly connected to the other end of the rotating pointer. The sliding resistor block is arranged on the sliding resistor disc in a sliding contact mode, and the output voltage signal of the sliding resistor is the braking intension signal of a brake control unit. According to the variable resistance hand control brake maneuvering device, fingers are used for controlling, a braking intension sensing function is achieved, the phenomenon of mistakenly stepping an accelerator pedal in the emergency braking process can be effectively prevented, the structure is simple, control is light and convenient, sensitive response is achieved, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to a variable resistance type manual brake control device, which belongs to the technical field of vehicle brakes. Background technique [0002] At present, the electric vehicle industry at home and abroad is in the stage of gradually moving towards industrialization. Usually, the existing fuel vehicles are partially modified and barely matched, resulting in problems such as increased vehicle weight, imperfect structural layout, and interference in the performance of various subsystems. The electrified chassis is composed of a brake-by-wire system, electric steering system, and electronically controlled suspension system. The entire chassis is controlled electronically, and the signal is transmitted through the CAN bus, which is coordinated and controlled by the vehicle controller. It is the development direction of the electric vehicle chassis. . [0003] The braking system is an important part of the automobile chassis, which i...

Problems solved by technology

However, the resistance piece of the double variable resistor is installed on the upper casing, and the sliding piece is fixed on the button, which is inconvenient to install, and because the button will deviate from the central axis and the displacement of the button is too small, it will affect the use of the double variable resistor.
