Abstract
The utility model pertains to an automobile part which relates to a brake drum of vehicle which is adopted in the brake system of highway transport vehicle. The brake drum of vehicle comprises a cylindrical base with an internal hole while a plurality of longitudinal grooves is evenly disposed on the outside cylindrical surface of the base. The utility model can assist in heat radiating for the car axle and the braking part, thereby improving the operational reliability and the service life of the car axle parts.
Description
Technical field
The utility model belongs to vehicle component, relates to a kind of vehicle brake drum that uses in the braking system of highway transport vehicle.
Background technique
Employed brake drum is generally a cylindrical structural that has endoporus in the braking system of existing highway haulage vehicle.Can produce higher heat at vehicle driving and braking process middle (center) bearing and drag friction parts, if heat can not in time distribute, may and bring working life the operational reliability of each parts does not influence.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly can carry out auxiliary heat dissipation to axletree and brake member, thus can improve the axletree parts operational reliability and working life vehicle brake drum.
Vehicle brake drum of the present utility model includes a columniform matrix that has endoporus, is evenly distributed with a plurality of grooves longitudinally on the external cylindrical surface of matrix.In addition, also have a plurality of breach at the end face of matrix and the intersection of external cylindrical surface.
The utility model is owing to be provided with breach and groove on the matrix end face of brake drum and external cylindrical surface, thereby the brake drum rotation time can produce stronger air-flow, thereby the heat that brake member and bearing are produced is effectively distributed, and has improved the operational reliability of axletree and the working life of parts.
Description of drawings
Fig. 1 is the utility model embodiment's a perspective view.
Embodiment
As shown in the figure, be evenly distributed with many grooves 2 longitudinally on the external cylindrical surface of the matrix 1 of vehicle brake drum of the present utility model, at the intersection of the end face edge of matrix and external cylindrical surface a plurality of breach 3 that distribute.
Claims (2)
1, a kind of vehicle brake drum includes a columniform matrix (1) that has endoporus, it is characterized in that: be evenly distributed with a plurality of grooves longitudinally (2) on the external cylindrical surface of matrix.
2, vehicle brake drum according to claim 1 is characterized in that: have a plurality of breach (3) at the end face of matrix and the intersection of external cylindrical surface.
