ABS actuator device unit for a cargo cycle and a cargo cycle provided with such device

Cargo cycle, in particular cargo bicycle with an electric motor for pedal assistance, comprising:

• a front wheel unit, with single or double wheel, carried by a front fork of the cycle,
• a frame, including a steering tube in which there is rotatably mounted a handlebar shaft connected to the handlebar of the cycle,
• a front extension of the frame of the cycle, which rotatably supports a shaft of the front fork of the cycle around an axis spaced forward with respect to the rotation axis of the handlebar of the cycle,
• a luggage compartment container mounted on the front extension of the frame, and
• a steering linkage which connects the handlebar shaft with the shaft of the front fork,
• wherein said cycle comprises a front hydraulic braking system including:
• a front disc brake associated with the front wheel and including a brake caliper provided with an actuator hydraulic cylinder,
• a master hydraulic cylinder associated with a lever for actuating the front brake, which-when actuated-transfers pressurised fluid to the actuator hydraulic cylinder of the brake caliper,
• an ABS hydraulic actuator device, interposed in the hydraulic connection between the master hydraulic cylinder and the actuator hydraulic cylinder of the brake caliper and which can be activated to reduce the pressure of the fluid supplied to the actuator hydraulic cylinder when, following an actuation of the aforementioned brake lever, a tendency to locking the front wheel unit is detected, and
• an electronic control unit configured and programmed to activate said ABS hydraulic actuator device when-following the actuation of the aforementioned brake lever-said electronic control unit detects a tendency to locking the front wheel unit based on the information sent to said electronic control unit by one or more sensors;
• and
• said braking system configured on the basis of a condition in which the luggage compartment container is fully loaded, and the ABS hydraulic actuator device configured on the basis of a condition in which the luggage compartment container is empty;
• said ABS hydraulic actuator device is mounted on said luggage compartment container;
• wherein said electronic control unit is mounted adjacent to said ABS hydraulic actuator device;
• the ABS hydraulic actuator device and/or the electronic control unit are mounted on a support plate provided with a covering casting which protects said actuator device and said electronic control unit, such that in a condition of maximum lateral inclination of the cycle, said ABS actuator device and the electronic control unit are spaced from the ground and protected from an impact with the ground.
