GB/T 24936 Terminology of all-terrain vehicles3 Terms and definitionsThe terms and definitions defined in GB/T 24936 and the following apply to this document. 3.1 Controller A component directly operated by the driver to provide the energy required for braking or control to the energy transmission device. 3.2 Energy transmission device A combination of components that connect the functions of the controller and the brake. 3.3 Service brake system servicebrakesystem A braking system that slows down a moving vehicle. 3.4 Combined brake system; CBS A service brake system in which the brakes on all wheels are controlled by a single controller. 3.5 Emergency brake system secondary brake system A second service brake system installed on a vehicle equipped with a linked brake system. 3.6 Braking system that controls the brakes on all wheels. Note. The system is controlled by a single controller for two or more subsystems. Failure of any subsystem (such as system failure caused by hydraulic pipeline leakage) does not affect the Other subsystem functions. 3.7 enginedisconnected The engine is disconnected from the drive wheels. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 24926-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 24926-2024_English as soon as possible, and keep you informed of the progress.
