The invention relates to the technical field of
truck braking, in particular to a
truck wheel disc type braking device long in service life and resistant to abrasion and a manufacturing process thereof.The
truck wheel disc type braking device comprises a back plate and is characterized in that a silencing plate used for silencing in the braking process is installed on one side of the back plate, and a plurality of braking mechanisms are arranged on the back plate; the
brake mechanisms are fixedly connected with the back plate through fixing mechanisms, cooling mechanisms are arranged on the back plate, the silencing plate and the
brake mechanisms, a control mechanism is installed on one
brake mechanism, and the cooling mechanisms are connected with the control mechanism. Wherein one braking mechanism is provided with the buffering mechanism, when a driver steps on the brake pedal, the braking mechanisms abut against the discs at the positions of the wheels, braking is achieved, the control mechanism abuts against the discs while braking is conducted,
water leakage of the control mechanism is controlled, heat dissipation of the braking mechanisms is achieved, and loss of a brake
assembly is reduced.
