Problems solved by technology

In the electric car disclosed in this application, the front axle and the rear axle are divided into two circuits that are both related and independent. When any circuit breaks down, the normal operation of the other circuit will not be affected to ensure the reliability of braking. The trolley disclosed in the application only has a front brake circuit and a rear brake circuit, while the current trolley bus has a longer body and more axles because it needs to have a larger passenger capacity. The braking structure adopted by the tram in this application Not suitable for trolleybuses with more axles

Embodiment 1

[0076] A trolley bus, including a car body and a vehicle electronic control unit (vehicle ECU), which is provided with 6 axles, which are numbered from the front to the rear as the No. 1 axle to the No. 6 axle. The trolley bus can run in both directions. Both ends of the trolley bus are provided with a driving area and an instrument panel, the instrument panel is provided with an emergency brake switch, and the driving area is provided with an electric brake main valve and a parking brake control valve. The braking system of the trolley bus includes an air source subsystem and a ventilation pipeline subsystem, and also includes a brake control subsystem and an electrical system, and the wind source subsystem and the brake control subsystem pass through the ventilation pipeline sub-system system connection, the electrical system and the braking control subsystem are connected through a circuit.

[0077] The wind source subsystem meets the requirements of GB 7258-2012, that is, ...

Embodiment 2

[0081] The trolley bus braking system also includes an electronically controlled air suspension subsystem (ECAS), and the ECAS is connected to the wind source subsystem through pipelines and connected to the electrical system through circuits.

[0082] The electronically controlled air suspension subsystem includes an ECAS solenoid valve, an inductive height valve, a two-way one-way valve, an air intake valve, a pressure sensor and an air bag. ECAS solenoid valves are arranged on the No. 2 wheel shaft and the No. 5 wheel shaft, wherein the ECAS solenoid valve on the No. 2 wheel shaft is connected with the two-way one-way valve set on the No. The pressure sensor and the air bag on the No. 2 wheel shaft are connected through a pipeline to connect the pressure sensor and the air bag on the No. 2 wheel shaft, and the pressure sensor and the air bag on the No. 3 wheel shaft are connected through a line of pipelines; The ECAS solenoid valve is connected to the two-way one-way valve ...

Embodiment 3

[0085] The brake control subsystem includes an electric brake master valve, a dual-control relay valve, a two-way one-way valve, an emergency relay valve, a single-channel module, ABS and a brake.

[0086] The electric brake master valve has two independent air brake circuits, and the air outlet of each air brake circuit leads to a brake control pipeline, that is, the electric brake master valve leads to two independent air brake circuits. Brake control line. There are two electronically controlled brake master valves, which are respectively set in the driving areas at both ends of the trolley bus, and one of the electronically controlled brake master valves (No. The gas storage tank C01.01, C01.02 of the air outlet is connected, and another electronically controlled brake master valve (No. 2 electric control brake master valve) is connected to the air storage tank C06.01, C06. 02 Air outlet connection. There are dual-control relay valves on the No. 1 axle, No. 3 axle, No. 4...

Abstract

The invention provides a trolley bus braking system and a trolley bus. The trolley bus braking system comprises an air source subsystem, a ventilation pipeline subsystem, an electrical subsystem, an electrically controlled air suspension (ECAS) subsystem, and a braking control subsystem; the air source subsystem is connected with the ECAS subsystem and the braking control subsystem through the ventilation pipeline subsystem; the electrical subsystem is connected with the ECAS subsystem and the braking control subsystem through a circuit; the braking control subsystem is internally provided with single-channel modules; the single-channel modules comprise gas solenoid valves, exhaust solenoid valves, standby pressure valves, relay valves, pressure sensors and electronic control units, and are arranged on all axles of the trolley bus. The trolley bus adopts the trolley bus braking system. The trolley bus braking system is suitable for the trolley bus with the multiple axles, and thus thetrolley bus has better braking performance.

Description

technical field [0001] The invention relates to the field of trolley buses, in particular to a trolley bus braking system and a trolley bus. Background technique [0002] Trolley bus is a kind of road public transportation that is usually powered by overhead catenary, driven by motor, and does not rely on fixed rails. Trolley bus is known as "green bus", which has the advantages of energy saving, environmental protection, comfort and sanitation, cheap and flexible. The main function of the trolley bus is to carry passengers, and generally there is no independent right of way, and it is easily affected by other vehicles and pedestrians during operation. Therefore, it is necessary for the trolley bus to have good braking performance to ensure the safety of people inside and outside the car. [0003] The invention patent application with the application number 201810104956.4 discloses an electric car with high-efficiency braking, including a car body, the front axle brake and r...
