Abstract

Problem to be solved in the utility model is: provide the drum brake brake block that a kind of structure is more stable, comprise body, described body is made up of some supporting networks, between described supporting network and upper and lower surface be equipped with friction material; What described body surface was uneven is distributed with increasing abrasive particle, and described body is provided with some through mounting holes.Beneficial effect is: by adopting the utility model, and brake block is more prone to ensure the stable of its structure, adds safety coefficient simultaneously.

Description

Drum brake brake block

Technical field

The utility model relates to automobile brake technical field, particularly relates to a kind of drum brake brake block.

Background technique

Drum brake is also block brake, is to compress on the brake wheel to realize brake by brake slipper.Drum brake is the braking system of Earlier designs, and the design of its brake drum has just been used on carriage, until just start in automotive industry extensive use about nineteen twenty for 1902.The main flow of drum brake is internal tensional type, drum brake utilizes brake transmission mechanism to make brake shoe be pressed on inside brake drum by brake strip, thus generation braking force, make wheel decelerates as required or stop in the shortest distance, to guarantee traffic safety, and ensure that automobile parking reliably can not automatic sliding.In nearly 30 years, drum brake has progressively exited and has made way for disk type braker on car field.But because cost compare is low, still use in some economic class cars, be mainly used in the smaller trailing wheel of brake load and parking braking, heavily block at some and still adopt drum brake with field of agricultural machinery.

The brake block used in drum brake in prior art often adopts and meets material and make, in continuous turning or this place needing even braking of down slope, its brake block is often easily overheated, and then generation deformation, this deformation will be fixed up after the cooling period, affect the braking quality in follow-up use, affect safety.

Model utility content

Problem to be solved in the utility model is: provide the drum brake brake block that a kind of structure is more stable.

The technical solution of the utility model is as follows: a kind of drum brake brake block, comprises body, and described body is made up of some supporting networks, between described supporting network and upper and lower surface be equipped with friction material; What described body surface was uneven is distributed with increasing abrasive particle, and described body is provided with some through mounting holes.

Further, described supporting network is that aramid fibre is composited high strength rack.

Further, described friction material is that ceramic fiber, molybdenum dioxide and antimony sulphide are composited.

The beneficial effects of the utility model are: by adopting the utility model, and brake block is more prone to ensure the stable of its structure, adds safety coefficient simultaneously.

Wherein: 1, body, 2, increase abrasive particle,

3, mounting hole, 4, supporting network,

5, friction material.

Embodiment

Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.

As shown in Figure 1 and Figure 2, a kind of drum brake brake block, high strength aramid fibre " material for antiballistic protective clothing " is adopted to be combined into high strength supporting network 4, strengthen the toughness of brake block product, prevent product be full of cracks in the presence of a harsh environment, fall the phenomenons such as block, brokeback, fragmentation, for safety traffic provides safeguard.Add and increase abrasive particle 2, improve Wear Resistance energy, significantly promote than conventional brake block wear-resisting property, have longer working life.The friction material 5 that the complex fiber material adopting ceramic fiber, molybdenum dioxide and antimony sulphide to be composited is made, pursues the perfection balance of the performances such as braking effect, wear-resisting property, impact strength and protection antithesis, has better performance than Single Fiber.

Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
