Embodiment approach

[0035] According to one embodiment, the locking mechanism 11 includes a locking part and a driving part. The locking part includes locking actuators 15A and 15B, a rocker arm 12 , a slider 13 and a guide rail 14 , and a linear displacement sensor (not shown) provided in the guide rail 14 . When the slider 13 moves to different positions, the linear displacement sensor will send different electrical signals to the brake controller 40. The brake controller 40 is calibrated in the early stage, and the electrical signals of different gears are calibrated. When the slider moves to the corresponding In the corresponding gear position, the brake controller 40 will send an opening command to the accumulator solenoid valve 24 or 27 .

[0036] The driving part includes an accumulator 30 , two oil inlet solenoid valves 24 and 27 , an oil drain valve 29 , oil inlet pipes 23 and 26 , and oil outlet pipes 25 and 28 . The connection relationship of these components will be described in deta...

Abstract

The invention relates to an electrical park brake used for a motor vehicle and a parking braking control method of the electrical park brake. The electrical park brake comprises a lock-up mechanism and a decelerating mechanism, wherein the lock-up mechanism comprises a rocker arm, a slider, a guide rail, a first locking actuator and a second locking actuator, the first locking actuator is providedwith a first lock-up pin, and the second locking actuator is provided with a second lock-up pin; the front end of the rocker arm is connected to the decelerating mechanism, the tail end of the rockerarm is connected with the slider, the slider can slide front and back in the guide rail under the action of the rocker arm, and the guide rail is provided with a first locking actuator and a second locking actuator. After the slider moves to a corresponding gear position in the guide rail, the first lock-up pin or the second lock-up pin can move so as to stop the slider from moving back. By meansof the electrical park brake, the space of a cab can be increased, more convenience is brought to parking, and parking is easier.

Description

technical field [0001] The invention relates to an electronic hand brake for a tractor and a parking brake control method thereof, which can be extended and applied to the technical field of automobile braking. Background technique [0002] Electronic handbrakes are widely used in passenger cars, but are rarely used on tractors. Its working principle is basically the same as that of mechanical handbrakes, but the control method is different. The previous mechanical handbrake lever has been changed to electronic button control. It is simpler and saves space in the cab. [0003] For example, Chinese patent CN105531166A discloses an electric braking device with a parking function that can prevent the danger of accidental disengagement of the parking brake when the brake pedal is operated in the state where the parking brake operation is completed. There are: a service brake control unit that activates the electric motor when there is an operation of the brake pedal; a parking ...
