Abstract

The utility model discloses a compound brake pedal assembly. The compound brake pedal assembly comprises a pedal and a push rod, wherein the pedal is hinged on a bracket; a certain distance is kept between the end part of the push rod and the pedal; an electric brake component is arranged in the compound brake pedal assembly; a control element in the electric brake component is connected with the pedal and the bracket; and a potentiometer used for measuring the relative position between the pedal and the bracket is also arranged in the compound brake pedal assembly. In the compound brake pedal assembly, a simple structure is adopted, and regenerative braking using recovered braking energy is combined with the conventional frictional braking, so that the compound brake pedal assembly has the regenerative braking energy recovery function, and has the advantages of simple structure and convenience in operation and maintenance.

Description

A composite brake pedal assembly

technical field

The utility model relates to a brake device, in particular to a composite brake pedal assembly.

Background technique

Known brake pedal assembly, its structure comprises pedal, return spring, the pedal long arm that is connected with pedal and the support that is connected with automobile frame bottom plate, and described pedal long arm is rotatably connected on the support, returns Both ends of the spring are respectively connected to the bracket and the pedal, and a push rod is connected to the far-axis end of the long arm of the pedal, and the push rod is connected to the braking device. When the driver steps on the pedal, the long arm of the pedal will push the push rod to move, and the push rod will drive the brake device to move, so as to achieve the purpose of braking and deceleration. When the pedal is released, the pedal will reset under the action of the return spring.

From the perspective of energy conversion, the energy generated by the locomotive during braking is considerable. Therefore, systematic research on the related technologies of regenerative energy absorption and application on locomotives can increase the efficiency of regenerative energy recovery, while the existing However, this kind of brake pedal assembly cannot meet the energy recovery requirements. Although some brake pedals with the function of energy recovery have been developed, most of them have complex structures, short service life, and inconvenient maintenance, so they are difficult to be popularized. application.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a composite brake pedal assembly with energy recovery function, simple structure, and convenient operation and maintenance.

A composite brake pedal assembly, including a pedal and a push rod. The pedal is hinged on the bracket. The key point of its structure is that there is a distance between the end of the push rod and the pedal. An electric brake assembly is also arranged in the electric brake assembly, the control part in the electric brake assembly is connected with the pedal and the bracket, and a potentiometer for measuring the position of the pedal relative to the bracket is also arranged in the composite brake pedal assembly.

Add an electric brake assembly (that is, an electric brake) to the pneumatic brake device composed of a push rod, and make a distance between the end of the push rod and the pedal, so that when the pedal is stepped on, when the pedal is not in contact with the push rod When they are in contact with each other, the electric brake assembly first acts and brakes until the pedal contacts the push rod. When the pedal contacts the push rod, the pneumatic brake device mainly driven by the push rod will work.

The electric brake assembly includes a rocker and a roller arranged at one end of the rocker. The other end of the rocker is hinged to the bracket or to the pedal, and the roller is always in contact with the pedal or the bracket.

The potentiometer is either coaxial with the pedal rotating shaft, or arranged at an angle between the pedal and the bracket.

In summary, the utility model has the advantages of:

The utility model adopts a simple structure and combines regenerative braking for recovering braking energy with conventional friction braking, so that the composite brake pedal has the function of regenerative braking energy recovery, and it has a simple structure and is convenient for operation and maintenance. The advantages.
