1results about How to "Guaranteed braking performance" patented technology

The utility model discloses a heavy truck rear axle rear brake dust cover, including dust cover body, is set up with two circumferential equidistance distribution's reserved slot on the dust cover body, and two reserved slots are fixedly connected with the through frame and the heat dissipation frame respectively in respectively, is provided with passive flow guide module on the through frame, passive flow guide module includes static plate, and static plate is located the outside of through frame, and the inside wall fixed connection of static plate's outside and dust cover body. The utility model discloses a heavy truck rear axle rear brake dust cover has can make device utilize the inertia on counterweight when heavy truck is braking and open the grating plate to guide the airflow to enter dust cover body again and export from the heat dissipation frame mode, and the heat of the brake is produced and is waited, thereby effectively reduced the heat of the brake in dust cover body, ensured the heat accumulation of heavy truck brake, avoided heat exhaustion, guaranteed the brake performance of heavy truck, improved the effect of the travel safety of heavy truck.
