Abstract
The invention belongs to vehicle parts, it relates to a vehicle braking drum used in braking system of highway transportation vehicle. The vehicle braking drum includes a cylindrical matrix with inner hole. On the external cylinder of matrix uniform distribute several vertical grooves. The invention can do auxiliary heat dissipation on axle and braking parts, so as to improve operation reliability and service life of axle parts.
Description
Technical field
The invention belongs to vehicle component, relate to a kind of vehicle brake drum that in the braking system of highway transport vehicle, uses.
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 by this invention 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 invention 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 present invention 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 has strengthened the disturbance to air, 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 perspective view of the embodiment of the invention.
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 invention, 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.
