Problems solved by technology

[0003] Most of the current brake system experimental equipment directly uses the hydraulic station to provide hydraulic power for the brake pipeline. Although the pressure of the brake pipeline can be effectively controlled, there is no real and effective simulation of the process of depressing the brake pedal for braking. , it is impossible to collect and research parameters such as brake pedal force, pedal stroke, and real vehicle brake pedal, vacuum booster, and brake master cylinder

Abstract

The invention discloses a brake pedal force simulating device, which is characterized in that a cylinder with a control element is arranged on a rack; a piston rod of the cylinder is connected with a connector through screw thread; a synchronous plate extended to one side is fixedly connected to the connector; a pressure sensor is arranged at the front end of the connector, and the pressure sensor is propped against a brake pedal arranged on the rack in a direction of treading the brake pedal by using a roller at the front end of the pressure sensor; and a popup displacement sensor parallel to the piston rod is arranged on one side of the cylinder, and a contact of the popup displacement sensor is propped against the synchronous plate. The brake pedal force simulating device serving as an automobile braking system test device can realize simulation of a process of treading the brake pedal, and has the advantages of simple structure, convenient arrangement, accurate control and high automation degree.

Description

technical field [0001] The invention belongs to automobile bench test equipment, more specifically, a pedal force simulation device for realizing the action of stepping on the brake pedal in the test of the automobile brake system. Background technique [0002] The automobile braking system is an important link to ensure the safety of vehicles and personnel. In modern automobile testing, the performance test of the braking system is particularly important. More and more tests involve the control and simulation of the braking process, as well as the brake pedal force. , brake travel, brake line pressure and other data collection. [0003] Most of the current brake system experimental equipment directly uses the hydraulic station to provide hydraulic power for the brake pipeline. Although the pressure of the brake pipeline can be effectively controlled, there is no real and effective simulation of the process of depressing the brake pedal for braking. , It is impossible to co...
